    This timely volume provides a comprehensive review of current technology for all ocean energies. It opens with an analysis of ocean thermal energy conversion (OTEC), with and without the use of an intermediate fluid. The historical and economic background is reviewed, and the geographical areas in which this energy could be utilized are pinpointed. The production of hydrogen as a side product, and environmental consequences of OTEC plants are considered. The competitiveness of OTEC with conventional sources of energy is analysed. Optimisation, current research and development potential are also examined. Separate chapters provide a detailed examination of other ocean energy sources. The possible harnessing of solar ponds, ocean currents, and power derived from salinity differences is considered. There is a fascinating study of marine winds, and the question of using the ocean tides as a source of energy is examined, focussing on a number of tidal power plant projects, including data gathered from China, Australia, Great Britain, Korea and the USSR. Wave energy extraction has excited recent interest and activity, with a number of experimental pilot plants being built in northern Europe. This topic is discussed at length in view of its greater chance of implementation. Finally, geothermal and biomass energy are considered, and an assessment of their future is given. The authors also distinguished between energy schemes which might be valuable in less-industrialized regions of the world, but uneconomical in the developed countries. A large number of illustrations support the text. This book will be of particular interest to energy economists, engineers, geologists and oceanographers, and to environmentalists and environmental engineers

    The Ocean Renewable Energy Group (OREG) is a collaboration between Canadian Industry, academia and government that provides leadership to advocate for and accelerate the development of a Canadian ocean renewable energy sector that can serve domestic needs and reach a global market. Approaches to ocean renewable energy were reviewed in this PowerPoint presentation. It was noted that no market leader in ocean renewable energy has emerged, but that the industry has the potential for a more rapid adoption curve than the wind power industry. The integration of ocean renewable energy with offshore wind power production was discussed, as well as hydrogen production, remote electrification, and the production of potable water through desalination. Various incentives and international demonstration projects were reviewed and the goals of OREG were outlined. The forming of strategic alliances with other global organizations was discussed, as well as OREG's plans to contribute to the education of sources of capital to facilitate the commercialization of Canadian technologies. It was noted that pilot plants are planned with BC Hydro in 2007. Issues concerning environmental assessments were discussed. It was suggested that as the cost of traditional generation rises, investment in ocean energy development may reduce risks to investors and ratepayers. Issues concerning funding were examined and the OREG strategy and action plan was reviewed. Research and development themes were outlined. It was suggested that British Columbia's ocean energy regime provides a unique competitive advantage, as did natural winds for Denmark in the early 1980s. Pioneer sites and the creation of a supportive climate were discussed, as well as issues concerning regulators and grid connection investment. A supply chain was outlined and details of various companies involved in ocean energy development were presented. refs., tabs., figs

    This annual evaluation is a synthesis of works published in 2006. Comparisons are presented between the wind power performances and European Commission White Paper and Biomass action plan objectives. The sector covers the energy exploitation of all energy flows specifically supplied by the seas and oceans. At present, most efforts in both research and development and in experimental implementation are concentrated on tidal currents and wave power. 90% of today worldwide ocean energy production is represented by a single site: the Rance Tidal Power Plant. Ocean energies must face up two challenges: progress has to be made in finalizing and perfecting technologies and costs must be brought under control. (A.L.B.)

    The earth, covered more than 70.8% by the ocean, receives most of its energy from the sun. Solar energy is transmitted through the atmosphere and efficiently collected and stored in the surface layer of the ocean, largely in the tropical zone. Some of the energy is re-emitted to the atmosphere to drive the hydrologic cycle and wind. The wind field returns some of the energy to the ocean in the form of waves and currents. The majority of the absorbed solar energy is stored in vertical thermal gradients near the surface layer of the ocean, most of which is in the tropical region. This thermal energy replenished each day by the sun in the tropical ocean represents a tremendous pollution-free energy resource for human civilization. Ocean Thermal Energy Conversion (OTEC) technology refers to a mechanical system that utilizes the natural temperature gradient that exists in the tropical ocean between the warm surface water and the deep cold water, to generate electricity and produce other economically valuable by-products. The science and engineering behind OTEC have been studied in the US since the mid-seventies, supported early by the U.S. Government and later by State and private industries. There are two general types of OTEC designs: closed-cycle plants utilize the evaporation of a working fluid, such as ammonia or propylene, to drive the turbine-generator, and open-cycle plants use steam from evaporated sea water to run the turbine. Another commonly known design, hybrid plants, is a combination of the two. OTEC requires relatively low operation and maintenance costs and no fossil fuel consumption. OTEC system possesses a formidable potential capacity for renewable energy and offers a significant elimination of greenhouse gases in producing power. In addition to electricity and drinking water, an OTEC system can produce many valuable by-products and side-utilizations, such as: hydrogen, air-conditioning, ice, aquaculture, and agriculture, etc. The potential of these

  10. Ocean zoning for conservation, fisheries and marine renewable energy: assessing trade-offs and co-location opportunities.

    2015-04-01

    Oceans, particularly coastal areas, are getting busier and within this increasingly human-dominated seascape, marine biodiversity continues to decline. Attempts to maintain and restore marine biodiversity are becoming more spatial, principally through the designation of marine protected areas (MPAs). MPAs compete for space with other uses, and the emergence of new industries, such as marine renewable energy generation, will increase competition for space. Decision makers require guidance on how to zone the ocean to conserve biodiversity, mitigate conflict and accommodate multiple uses. Here we used empirical data and freely available planning software to identified priority areas for multiple ocean zones, which incorporate goals for biodiversity conservation, two types of renewable energy, and three types of fishing. We developed an approached to evaluate trade-offs between industries and we investigated the impacts of co-locating some fishing activities within renewable energy sites. We observed non-linear trade-offs between industries. We also found that different subsectors within those industries experienced very different trade-off curves. Incorporating co-location resulted in significant reductions in cost to the fishing industry, including fisheries that were not co-located. Co-location also altered the optimal location of renewable energy zones with planning solutions. Our findings have broad implications for ocean zoning and marine spatial planning. In particular, they highlight the need to include industry subsectors when assessing trade-offs and they stress the importance of considering co-location opportunities from the outset. Our research reinforces the need for multi-industry ocean-zoning and demonstrates how it can be undertaken within the framework of strategic conservation planning. Copyright © 2015 Elsevier Ltd.

    Research progress is reported on developing Ocean Thermal Energy Conversion (OTEC) systems that will provide synthetic fuels (e.g., methanol), energy-intensive products such as ammonia (for fertilizers and chemicals), and aluminum. The work also includes assessment and design concepts for hybrid plants, such as geothermal-OTEC (GEOTEC) plants. Another effort that began in the spring of 1982 is a technical advisory role to DOE with respect to their management of the conceptual design activity of the two industry teams that are designing offshore OTEC pilot plants that could deliver power to Oahu, Hawaii. In addition, a program is underway in which tests of a different kind of ocean-energy device, a turbine that is air-driven as a result of wave action in a chamber, are being planned. This Quarterly Report summarizes the work on the various tasks as of 31 December 1982.

    Engineers' dreams and fossil energy replacement schemes can come true. Man has been tapping the energy of the sea to provide power for his industries for centuries. Tidal energy combined with that of waves and marine winds rank among those most successfully put the work. Large scale plants are capital intensive but smaller ones, particularly built in China, have proven profitable. Since the initiation of the St Malo project in France, similar projects have gone into active service where methods have been devised to cut down on costs, new types of turbines developed and cost competitiveness considerably improved. Tidal power has enormous potential. The book reviews recent progress in extracting power from the ocean, surveys the history of tidal power harnessing and updates a prior publication by the author.

  16. The sequestration switch. Removing industrial CO2 by direct ocean absorption

    International Nuclear Information System (INIS)

    Ametistova, Lioudmila; Briden, James; Twidell, John

    2002-01-01

    This review paper considers direct injection of industrial CO 2 emissions into the mid-water oceanic column below 500 m depth. Such a process is a potential candidate for switching atmospheric carbon emissions directly to long term sequestration, thereby relieving the intermediate atmospheric burden. Given sufficient research justification, the argument is that harmful impact in both the Atmosphere and the biologically rich upper marine layer could be reduced. The paper aims to estimate the role that active intervention, through direct ocean CO 2 storage, could play and to outline further research and assessment for the strategy to be a viable option for climate change mitigation. The attractiveness of direct ocean injection lies in its bypassing of the Atmosphere and upper marine region, its relative permanence, its practicability using existing technologies and its quantification. The difficulties relate to the uncertainty of some fundamental scientific issues, such as plume dynamics, lowered pH of the exposed waters and associated ecological impact, the significant energy penalty associated with the necessary engineering plant and the uncertain costs. Moreover, there are considerable uncertainties regarding related international marine law. Development of the process would require acceptance of the evidence for climate change, strict requirements for large industrial consumers of fossil fuel to reduce CO 2 emissions into the Atmosphere and scientific evidence for the overall beneficial impact of ocean sequestration

    2011-07-01

    The demand for modern energy is accelerating in the Western Indian Ocean (coastal East Africa). A mixture of different energy sources will by necessity be the option for the long-term future and the most adequate solutions naturally vary between locations. The vast coastlines and many islands of the region make ocean energy (OE) a relevant field to explore. With an early understanding of the resources strategic planning towards sustainable development is facilitate. Moreover, early awareness facilitates a respectful integration of new technologies in the fragile and for local people invaluable ecosystems. This study provides a first assessment of the frontier OE technologies and corresponding resources in the region. Five renewable Ocean Energy technologies have been reviewed and the physical resource abundance for respective energy source has been screened based on available literature and databases. The Western Indian Ocean is shared between nine African countries and two French departments. The studied countries are the Comoros, Kenya, Madagascar, Mauritius, Mayotte, Mozambique, the Seychelles, Tanzania, and Reunion. The energy situation is insufficient throughout the region, either as consequence of lacking domestic energy sources or rudimentary grid extension. The results indicate that ocean energy resources are abundant in much of the region, but different sources have potential in different areas. Several countries have favourable physical conditions for extracting energy from waves and from the temperature gradient between the surface and deep water. Wave power is a young but currently available technology which can be utilized for both large- and small-scale applications. Ocean Thermal Energy Conversion is a technology under development that, once proven, may be applicable for large-scale power production. The physical conditions for small-scale tidal barrage power, tidal stream power, and ocean current power are less pronounced but may be of interest at

  1. Early onset of industrial-era warming across the oceans and continents.

    The evolution of industrial-era warming across the continents and oceans provides a context for future climate change and is important for determining climate sensitivity and the processes that control regional warming. Here we use post-ad 1500 palaeoclimate records to show that sustained industrial-era warming of the tropical oceans first developed during the mid-nineteenth century and was nearly synchronous with Northern Hemisphere continental warming. The early onset of sustained, significant warming in palaeoclimate records and model simulations suggests that greenhouse forcing of industrial-era warming commenced as early as the mid-nineteenth century and included an enhanced equatorial ocean response mechanism. The development of Southern Hemisphere warming is delayed in reconstructions, but this apparent delay is not reproduced in climate simulations. Our findings imply that instrumental records are too short to comprehensively assess anthropogenic climate change and that, in some regions, about 180 years of industrial-era warming has already caused surface temperatures to emerge above pre-industrial values, even when taking natural variability into account.

    Ocean energy is a novel renewable energy resource being developed as part of the push towards a 'Blue Economy'. The literature on ocean energy has focused on technical, environmental, and, increasingly, social and political aspects. Legal and regulatory factors have received less attention, despite their importance in supporting this new technology and ensuring its sustainable development. In this Issue Brief, we set out some key legal challenges for the development of ocean energy technologies, structured around the following core themes of marine governance: (i) international law; (ii) environmental impacts; (iii) rights and ownership; (iv) consenting processes; and (v) management of marine space and resources.

    The Oceanic Platform of the Canary Islands (PLOCAN) is a Governmental Consortium aimed to build and operate an off-shore infrastructure to facilitate the deep sea research and speed up the technology associated. This Consortium is overseen by the Spanish Ministry of Science and Innovation and the Canarian Agency for Research and Innovation. The infrastructure consists of an oceanic platform located in an area with depths between 50-100 meters, close to the continental slope and four kilometers off the coast of Gran Canaria, in the archipelago of the Canary Islands. The process of construction will start during the first months of 2010 and is expected to be finished in mid-year 2011. PLOCAN serves five strategic lines: an integral observatory able to explore from the deep ocean to the atmosphere, an ocean technology testbed, a base for underwater vehicles, an innovation platform and a highly specialized training centre. Ocean energy is a suitable source to contribute the limited mix-energy conformed in the archipelago of the Canary Islands with a total population around 2 million people unequally distributed in seven islands. Islands of Gran Canaria and Tenerife support the 80% of the total population with 800.000 people each. PLOCAN will contribute to develop the ocean energy sector establishing a marine testbed allowing prototypes testing at sea under a meticulous monitoring network provided by the integral observatory, generating valuable information to developers. Reducing costs throughout an integral project management is an essential objective to be reach, providing services such as transportation, customs and administrative permits. Ocean surface for testing activities is around 8 km2 with a depth going from 50 to 100 meters, 4km off the coast. Selected areas for testing have off-shore wind power conditions around 500-600 W/m2 and wave power conditions around 6 kW/m in the East coast and 10 kW/m in the North coast.

    The IEA Policy Pathway publications provide details on how to implement specific recommendations drawn from the IEA 25 Energy Efficiency Policy Recommendations. This Policy Pathway, jointly produced by the International Energy Agency and the Institute for Industrial Productivity, develops the critical steps for policy makers implementing energy management programmes for industry. Optimising energy use in industry is essential to improve industrial competitiveness and achieve wider societal goals such as energy security, economic recovery and development, climate change mitigation and environmental protection. While there is significant potential to decrease energy consumption in this sector, opportunities to improve energy efficiency are still under-exploited. Energy management programmes have shown to be instrumental in addressing many of the barriers that inhibit wide-scale uptake of energy management in industry. The Policy Pathway builds on lessons learned from country experiences and provides actionable guidance on how to plan and design, implement, evaluate and monitor energy management programmes for industry.

    An industry's relationship of supply and demand with the energy sector can be a critical factor in the stability of its economic performance. Furthermore, the patterns of industry dependence on energy industries can be a major characteristic of entire industrial structure. This research evaluates industries' impact scores for their overall influence on other industries and vulnerability to supply and demand shocks from the energy sector. The study utilizes a sample of Korea's industrial input–output tables from 2010 to 2012. Using a chain of complementary methodologies, this study finds that among four clusters, energy, services, and raw materials are key members that can spread energy shocks to other industries. Therefore, governments need to prepare effective energy efficiency policies for these target industries. - Highlights: • We analyze an industry's impact score of its vulnerability to energy shock and inter-industrial effects. • We utilize the sample of input-output tables in Korea from 2010 to 2012. • We implement simulation, PCA, TOPSIS, cluster analysis about energy shock and industrial trades. • Subsectors of energy, services, raw material are subject to energy shock and influential to others. • These bridge industries can be targets that require policies for effective energy efficiency.

    Various studies in different countries have shown that significant energy-efficiency improvement opportunities exist in the industrial sector, many of which are cost-effective. These energy-efficiency options include both cross-cutting as well as sector-specific measures. However, industrial plants are not always aware of energy-efficiency improvement potentials. Conducting an energy audit is one of the first steps in identifying these potentials. Even so, many plants do not have the capacity to conduct an effective energy audit. In some countries, government policies and programs aim to assist industry to improve competitiveness through increased energy efficiency. However, usually only limited technical and financial resources for improving energy efficiency are available, especially for small and medium-sized enterprises. Information on energy auditing and practices should, therefore, be prepared and disseminated to industrial plants. This guidebook provides guidelines for energy auditors regarding the key elements for preparing for an energy audit, conducting an inventory and measuring energy use, analyzing energy bills, benchmarking, analyzing energy use patterns, identifying energy-efficiency opportunities, conducting cost-benefit analysis, preparing energy audit reports, and undertaking post-audit activities. The purpose of this guidebook is to assist energy auditors and engineers in the plant to conduct a well-structured and effective energy audit.

    Industry uses around half of the electricity consumed in Finland. In 1999, this amounted to 42.3 TWh and 420 PJ of fuel. Despite the continual improvements that have been made in energy efficiency, energy needs look set to continue growing at nearly 2% a year. Finnish industrial output rose by some 5.5% in 1999. In energy-intensive sectors such as pulp and paper, output rose by 3.4%, in the metal industry by 4%, and in the chemical industry by 3.1%. Growth across Finnish industry is largely focused on the electrical and electronics industries, however, where growth last year was 24.3% The Finnish forest products industry used a total of 26.1 TWh of electricity last year, up 1% on 1998. This small increase was the result of the industry's lower-than-average operating rate in the early part of the year The metal industry used 7.2 TWh of electricity, an increase of 5.8% on 1998. Usage in the chemical industry rose by 2% to 5.2 TWh. Usage by the rest of industry totalled 3.8 TWh, up 2.3% on 1998. All in all, industry's use of electricity rose by 2% in 1999 to 42,3 TWh. Increased demand on industry's main markets in Europe will serve to boost industrial output and export growth this year. This increased demand will be particularly felt in energy-intensive industries in the shape of an increased demand for electricity. Overall, electricity demand is expected to grow by 3% this year, 1% more than industry's longterm projected electricity usage growth figure of 2%. The structure of industry's fuel use in Finland has changed significantly over the last 25 years. Oil, for example, now accounts for only some 10% of fuel use compared to the 40% typical around the time of the first oil crisis. Oil has been replaced by biofuels, peat, and natural gas. The pulp and paper industry is the largest industrial user of renewable energy sources in Finland, and uses wood-related fuels to cover nearly 70% of its fuel needs

    The employment, economic and energetic situation in various industrial branches and their importance for industry as a whole is mapped for Nordic countries. Future Nordic energy projects can base their attempts to decrease energy costs per unit on this report. In food and stimulants industry, chemical, glass and ceramic industry over 90% energy is used for processing while in steel- and metal-industry the processing consumes only about 25%. Rentability of new investments in energy saving should be considered in these branches against investments in automation, new equipment etc. Common Nordic energy-saving projects can provide much better energy economy. For instance 4% of USA energy which had formerly been used in drying processes is drastically decreased and if the USA result can be transferred to Nordic conditions DKr 160 million can be save. Prospective common projects are process-types like drying, spray-drying, heat treatments of mineral proproducts, and evaporation.

    Highlights: • Analytical tool was applied to estimate the energy efficiency indicator of energy intensive industries in Taiwan. • The carbon dioxide emission intensity in selected energy-intensive industries is also evaluated in this study. • The obtained energy efficiency indicator can serve as a base case for comparison to the other regions in the world. • This analysis results can serve as a benchmark for selected energy-intensive industries. - Abstract: Taiwan imports approximately 97.9% of its primary energy as rapid economic development has significantly increased energy and electricity demands. Increased energy efficiency is necessary for industry to comply with energy-efficiency indicators and benchmarking. Benchmarking is applied in this work as an analytical tool to estimate the energy-efficiency indicators of major energy-intensive industries in Taiwan and then compare them to other regions of the world. In addition, the carbon dioxide emission intensity in the iron and steel, chemical, cement, textile and pulp and paper industries are evaluated in this study. In the iron and steel industry, the energy improvement potential of blast furnace–basic oxygen furnace (BF–BOF) based on BPT (best practice technology) is about 28%. Between 2007 and 2011, the average specific energy consumption (SEC) of styrene monomer (SM), purified terephthalic acid (PTA) and low-density polyethylene (LDPE) was 9.6 GJ/ton, 5.3 GJ/ton and 9.1 GJ/ton, respectively. The energy efficiency of pulping would be improved by 33% if BAT (best available technology) were applied. The analysis results can serve as a benchmark for these industries and as a base case for stimulating changes aimed at more efficient energy utilization

    China is undergoing rapid industrialization and urbanization, with consequent dramatic increase in energy demand. Given energy scarcity, environmental pollution, energy security and energy cost constraints, energy conservation will be the major strategy in China's transition to a low-carbon economy. Since the metallurgy industry is a main sector of energy consumption, the efficiency of energy conservation in this industry will affect the future prospects of energy savings. This paper analyzes the energy conservation potential of China's metallurgy industry. First, seemingly unrelated regression method is applied to investigate the relationship between energy relative price, R&D input, enterprise ownership structure, enterprise scale and energy intensity of the metallurgy industry. Then, based on the SUR results, we use the scenario analysis method to predict energy consumption and savings potential in the industry in different scenarios. This paper provides references for China's government and metallurgy industry in formulating relevant energy conservation policies. - Highlights: • Seemingly unrelated regression method is applied to analyze the energy intensity of metallurgy industry. • We use the scenario analysis method to predict energy consuming and energy saving of Chinese metallurgy industry. • Provide references for China's government and metallurgy industry in formulating relevant energy conservation policies.

    -viable fashion presents a variety of challenges. Beyond the technology itself (and, especially, the effects on the technology of the harsh oceanic environment), it is important to consider the possible environmental impacts of commercial-scale implementation of oceanic energy extraction. Further, because such implementation represents a completely new undertaking, the human resources required do not exist, so education and training programs are critical to eventual success. This project, establishing a national open-ocean energy laboratory, was designed to address each of these three challenges in a flexible framework allowing for adaptive management as the project proceeded. In particular: the technology challenge, including resource assessment, evolved during the project to recognize and address the need for a national testing facility in the ocean for small-scale prototype MRE systems developed by industry; the environmental challenge became formalized and expanded during the permitting process for such a testing facility; and the human resources/societal challenges, both in terms of the need for education and training and in terms of public acceptance of MRE, stimulated a robust outreach program far beyond that originally envisioned at SNMREC. While all of these activities at SNMREC are ongoing, a number of significant milestones (in addition to the contributions listed in the appendices) were achieved under the auspices of this award. These include: Planning and site selection for the first-phase test facility, offshore of Dania Beach, FL, including some equipment for the facility, submission of an Interim Policy Lease Application to the U.S. Department of Interior’s Bureau of Ocean Energy Management (BOEM), and completion of an Environmental Assessment by BOEM and a positive Consistency Determination by the State of Florida; Measurements using acoustic profilers of the current structure and variability in the vicinity of the site under a variety of weather conditions

    Scott, G C

    1976-01-01

    The forest industries, which contribute 10% of New Zealand's factory production and consume 25% of all industrial energy (including self-generated sources such as waste liquors and wood wastes), were closely investigated to determine the extent to which imported energy sources can be substituted by local sources and savings made in the specific energy consumption of the industry's products. Issues considered as fundamental to the study were conservation of the nation's fossil fuels; nuclear power should be considered only after full study of its implications; restraints on the growth of energy demands; a greater emphasis on renewable energy resources; and new energy-intensive industries must account for the environmental and social costs of providing the energy. The study was commenced in February 1975 and involved a series of visits to all the major plants and a few representative smaller plants. Energy balances for all the major plants were prepared and are published in the text of the report. The forest-based industries have developed from a large number of small scattered sawmills, drawing from indigenous resources into a few large industrial units which are capital-intensive and produce a wide variety of products serving the home and export markets. They fall into four categories, roughly as follows: large integrated units; intermediate-size integrated mills; sawmills and chip plants; and manufacturing.

    1994-04-01

    Japan is clearly the leader in ocean energy technologies. The United Kingdom also has had many ocean energy research projects, but unlike Japan, most of the British projects have not progressed from the feasibility study stage to the demonstration stage. Federally funded ocean energy research in the US was stopped because it was perceived the technologies could not compete with conventional sources of fuel. Despite the probable small market for ocean energy technologies, the short sighted viewpoint of the US government regarding funding of these technologies may be harmful to US economic competitiveness. The technologies may have important uses in other applications, such as offshore construction and oil and gas drilling. Discontinuing the research and development of these technologies may cause the US to lose knowledge and miss market opportunities. If the US wishes to maintain its knowledge base and a market presence for ocean energy technologies, it may wish to consider entering into a cooperative agreement with Japan and/or the United Kingdom. Cooperative agreements are beneficial not only for technology transfer but also for cost-sharing

    2015-04-01

    Energy consumption in the industry represents today 1/5 of France's end-use energy consumption. Gas and electricity are the most consumed and represent 2/3 of the overall. The 5 most energy consuming industries are the following: paper and cardboard industry, food industry, rubber, plastic and other non-metallic mineral products industry, metallurgy and chemical industry. The reduction of the industry's energy consumption is explained by the decline of production, but above all by the energy efficiency improvement of the sector. Technological innovations in production means have indeed led to reduce energy consumption

    2013-11-01

    Numerical simulations are performed to validate a non-dimensional dynamic scaling procedure that can be applied to subsurface and deeply moored systems, such as hydrokinetic ocean renewable energy devices. The prototype systems are moored in water 400 m deep and include: subsurface spherical buoys moored in a shear current and excited by waves; an ocean current turbine excited by waves; and a deeply submerged spherical buoy in a shear current excited by strong current fluctuations. The corresponding model systems, which are scaled based on relative water depths of 10 m and 40 m, are also studied. For each case examined, the response of the model system closely matches the scaled response of the corresponding full-sized prototype system. The results suggest that laboratory-scale testing of complete ocean current renewable energy systems moored in a current is possible. This work was supported by the U.S. Southeast National Marine Renewable Energy Center (SNMREC).

    2007-01-01

    As methodology the ex-post analysis deserves more attention as a device to calibrate energy sector models. This paper studies the impact of energy prices and taxes on energy efficiency and carbon emissions of ten industrial sectors in the three Scandinavian countries. A database with sector-specific energy prices and taxes has been established, which allows the analysis to take various price reductions and tax exemptions better into account. A translog factor demand system estimation for a cross industry pooled model is explored and fixed effects across industries and time is estimated. The findings here confirm recent analyses which indicate higher long-term elasticities for industries than normally assumed in Scandinavian energy-sector models. With the observations on differences in energy-intensities among sectors and countries the findings allow for some optimism as to the opportunities for further decoupling between trends in gross value added, carbon emissions and energy consumption

    1983-06-01

    Systematic responses by the Japanese government and industry to the successive oil crises of the 1970s are yielding remarkable results; instead of the most vulnerable and technologically-dependent energy system in the world, Japanese industry is emerging as one of the world's most energy-efficient and a major source of the most advanced energy technologies. By the end of the century, if best available prognoses on fusion power technology prove close to accurate, Japan's energy industry will have assumed a technological leadership akin to that of its steel industry today. Significant energy conservation has been achieved by concerted efforts to promote less energy-intensive industries and by advances in technology and equipment for reducing energy consumption in key industries. In 1980, the Japanese government set targets for the development of new energy sources for the coming decade, which, if realized, will contribute substantially to a three-fold increase in non-petroleum energy supply by 1990, and a further doubling of alternative energy supplies by the end of the century. By the year 2000, Japanese reliance on petroleum is expected to decline from 88% in 1977 to 74.9%.

    Over a period of two years the NAP's Special Interest Group Energy (SIG-E) has dedicated itself to studying the way in which the process industry and its supply chain has been dealing with energy as a theme. In the past it was strongly believed that many opportunities were left unused and that different forms of cooperation inside the chain should contribute to accelerated improvement of energy efficiency in the process industry. Sixteen companies that are actively involved in the entire value chain have scrutinised their daily situation wondering how to operate more successfully. With approximately one quarter of total energy consumption the Dutch process industry is a major player in reaching national energy and climate objectives by 2020. The objective (improve energy efficiency by 2% annually) is as ambitious as that 'business as usual' is insufficient. A drastic change in how matters are approached is thus essential. The question is how to proceed? By analysing energy projects, in-depth interviews with decision makers in the industry, through literature searches and by organising lectures inside and outside the sector, SlG-E has been able to develop a true picture of the mechanisms concerning energy-related investments. Two major points of interest have been energy-oriented tendering (demand side) and the market introduction of innovations (supply side). The main problems of 'how to do more in the energy domain' is: (a) the process industry is insufficiently familiar with the capabilities of the supply chain, and (b) the supply chain is insufficiently aware of the questions that exist in the process industry. Therefore, the links in the value chain understand each other poorly. The answer to this problem is compound and consists of more interaction between the process industry and the supply chain (machine constructors, engineering firms and consultancies, education and research). As for the process industry: (a) Make improved energy

    2013-10-03

    Increasing energy consumption and depleting reserves of fossil fuels have resulted in growing interest in alternative renewable energy from the ocean. Ocean currents are an alternative source of clean energy due to their inherent reliability, persistence and sustainability. General ocean circulations exist in the form of large rotating ocean gyres, and feature extremely rapid current flow in the western boundaries due to the Coriolis Effect. The Gulf Stream system is formed by the western boundary current of the North Atlantic Ocean that flows along the east coastline of the United States, and therefore is of particular interest as a potential energy resource for the United States.

    2018-01-01

    Full Text Available Optimal utilization of renewable energy resources needs energy storage capability in integration with the electric grid. Ocean compressed air energy storage (OCAES can provide promising large-scale energy storage. In OCAES, energy is stored in the form of compressed air under the ocean. Underwater energy storage results in a constant-pressure storage system which has potential to show high efficiency compared to constant-volume energy storage. Various OCAES concepts, namely, diabatic, adiabatic, and isothermal OCAES, are possible based on the handling of heat in the system. These OCAES concepts are assessed using energy and exergy analysis in this paper. Roundtrip efficiency of liquid piston based OCAES is also investigated using an experimental liquid piston compressor. Further, the potential of improved efficiency of liquid piston based OCAES with use of various heat transfer enhancement techniques is investigated. Results show that adiabatic OCAES shows improved efficiency over diabatic OCAES by storing thermal exergy in thermal energy storage and isothermal OCAES shows significantly higher efficiency over adiabatic and diabatic OCAES. Liquid piston based OCAES is estimated to show roundtrip efficiency of about 45% and use of heat transfer enhancement in liquid piston has potential to improve roundtrip efficiency of liquid piston based OCAES up to 62%.

    Data on energy use in the manufacturing process of the wood products industry in 1974 are tabulated. The forest industries contributed 10% of New Zealand's factory production and consumed 25% of all industrial energy (including that produced from self-generated sources such as waste heat liquors and wood wastes) in that year. An evaluation of the potential for savings in process heat systems in existing production levels is shown to be 3% in the short, medium, and long-term time periods. The industry has a high potential for fuel substitution in all sectors. The payback periods for the implementation of the conservation measures are indicated.

    As part of its Industries of the Future strategy, the Industrial Technologies Program within the U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy works with energy-intensive industries to improve efficiency, reduce waste, and increase productivity. These seven Industries of the Future (IOFs) – aluminum, chemicals, forest products, glass, metal casting, mining, and steel – rely on several other so-called “supporting industries” to supply materials and processes necessary to the products that the IOFs create. The supporting industries, in many cases, also provide great opportunities for realizing energy efficiency gains in IOF processes.

    Small islands face difficult challenges to guarantee energy, freshwater and food supply, and sustainable development. The urge to meet their needs, together with the mitigation and adaptation plans to address climate change, have led them to develop renewable energy systems, with a special interest in Ocean Thermal Energy Conversion (OTEC) in tropical islands. Deep Ocean Water (DOW) is a resource that can provide electricity (through OTEC in combination with warm surface water), low temperatures for refrigeration, and nutrients for food production. In this paper we propose an Ocean Technology Ecopark (OTEP) as an integral solution for small islands that consists of an OTEC plant, other alternative uses of DOW, and a Research and Development (R&D) center. We present an application of OTEP to San Andres, a Colombian island that meets all the necessary conditions for the implementation of OTEC technology, water desalinization, and a business model for DOW.

    The statistics present the industry's energy consumption and composition, and the development from 1973 to 2003. In this period the composition of the energy consumption has changed considerably: a decrease in the consumption of liquid fuels and an increase in the consumption of natural gas and electric power. The energy consumption in the Danish industry decreased with almost 9 % from 2001 to 2003. This relatively large decrease was mainly due to the closing down of a steel factory. In the wood industry the energy consumption decreased with 36 % from 2001 to 2003, while the energy consumption in the electronics industry increased. (ln)

    This paper assesses energy efficiency in Swedish industry. Using unique firm-level panel data covering the years 2001–2008, the efficiency estimates are obtained for firms in 14 industrial sectors by using data envelopment analysis (DEA). The analysis accounts for multi-output technologies where undesirable outputs are produced alongside with the desirable output. The results show that there was potential to improve energy efficiency in all the sectors and relatively large energy inefficiencies existed in small energy-use industries in the sample period. Also, we assess how the EU ETS, the carbon dioxide (CO_2) tax and the energy tax affect energy efficiency by conducting a second-stage regression analysis. To obtain consistent estimates for the regression model, we apply a modified, input-oriented version of the double bootstrap procedure of Simar and Wilson (2007). The results of the regression analysis reveal that the EU ETS and the CO_2 tax did not have significant influences on energy efficiency in the sample period. However, the energy tax had a positive relation with the energy efficiency. - Highlights: • We use DEA to estimate firm-level energy efficiency in Swedish industry. • We examine impacts of climate and energy policies on energy efficiency. • The analyzed policies are Swedish carbon and energy taxes and the EU ETS. • Carbon tax and EU ETS did not have significant influences on energy efficiency. • The energy tax had a positive relation with energy efficiency.

    1995-01-01

    Taxation of the energy industries is an issue of major importance for each energy sector. This has always been the situation for the primary fossil fuel sectors but, with corporatization and privatization, is now also an issue for the electricity supply industry. This article examines the most significant forms of taxation affecting the major industry sectors, namely secondary taxation, corporate taxation and, as a consequence of the corporatization and privatization of the electricity supply industry, surrogate taxation as it affects that industry. While essentially considering secondary taxation, the paper also reviews corporate and surrogate taxes. Tax exemptions for various energy sector activities such as mining operations, exploration and rehabilitation related activities are outlined. It is considered that there is insufficient evidence of the influence of taxation and other factors on electricity pricing. 2 tabs

    During 1995, the Department of Energy`s Solar Industrial (SI) Program worked to bring the benefits of solar energy to America`s industrial sector. Scientists and engineers within the program continued the basic research, applied engineering, and economic analyses that have been at the heart of the Program`s success since its inception in 1989. In 1995, all three of the SI Program`s primary areas of research and development--solar detoxification, advanced solar processes, and solar process heat--succeeded in increasing the contribution made by renewable and energy-efficient technologies to American industry`s sustainable energy future. The Solar Detoxification Program develops solar-based pollution control technologies for destroying hazardous environmental contaminants. The Advanced Solar Processes Program investigates industrial uses of highly concentrated solar energy. The Solar Process Heat Program conducts the investigations and analyses that help energy planners determine when solar heating technologies--like those that produce industrial-scale quantities of hot water, hot air, and steam--can be applied cost effectively. The remainder of this report highlights the research and development conducted within in each of these subprograms during 1995.

    Two articles address the possibility of exploiting a higher than 20 degrees temperature difference between ocean surfaces and 1 km deep waters to produce electricity. The first article describes the operation principle in closed cycle and briefly presents the open cycle approach. The global energetic assessment is discussed. The author analyses available thermal resources in relationship with the main ocean streams. He outlines that the design of an ocean thermal energy project requires the acquisition and knowledge of a lot of data, modelling and simulations. In the second article, the author notices that past experiments highlighted the difficulties of implementation of the concept. He notably evokes works performed by Georges Claude during the 1920's, projects elaborated at the end of the 20. century, the realisation of a mini OTEC (Ocean Thermal Energy Conversion) station in Hawaii, the OTEC-1 project, a Japanese project in Nauru, the test of a suspended cold water duct, the net power producing experiment in the USA. Perspectives and costs are finally briefly discussed, and recent and promising projects briefly evoked (notably that by DCNS and Akuo Energy in Martinique)

    The IEA Policy Pathway publications provide details on how to implement specific recommendations drawn from the IEA 25 Energy Efficiency Policy Recommendations. This Policy Pathway, jointly produced by the International Energy Agency and the Institute for Industrial Productivity, develops the critical steps for policy makers implementing energy management programmes for industry. Optimising energy use in industry is essential to improve industrial competitiveness and achieve wider societal goals such as energy security, economic recovery and development, climate change mitigation and environmental protection.While there is significant potential to decrease energy consumption in this sector, opportunities to improve energy efficiency are still under-exploited. Energy management programmes have shown to be instrumental in addressing many of the barriers that inhibit wide-scale uptake of energy management in industry. The Policy Pathway builds on lessons learned from country experiences and provides actionable guidance on how to plan and design, implement, evaluate and monitor energy management programmes for industry.

  18. Interpreting the implied meridional oceanic energy transport in AMIP

    Randall, D.A.; Gleckler, P.J.

    1993-09-01

    The Atmospheric Model Intercomparison Project (AMIP) was outlined in Paper No. CLIM VAR 2.3 (entitled open-quote The validation of ocean surface heat fluxes in AMIP') of these proceedings. Preliminary results of AMIP subproject No. 5 were also summarized. In particular, zonally averaged ocean surface heat fluxes resulting from various AMIP simulations were intercompared, and to the extent possible they were validated with uncertainties in observationally-based estimates of surface heat fluxes. The intercomparison is continued in this paper by examining the Oceanic Meridional Energy Transport (OMET) implied by the net surface heat fluxes of the AMIP simulations. As with the surface heat fluxes of the AMIP simulations. As with the surface heat fluxes, the perspective here will be very cursory. The annual mean implied ocean heat transport can be estimated by integrating the zonally averaged net ocean surface heat flux, N sfc , from one pole to the other. In AGCM simulations (and perhaps reality), the global mean N sfc is typically not in exact balance when averaged over one or more years. Because of this, an important assumption must be made about changes in the distribution of energy in the oceans. Otherwise, the integration will yield a non-zero transport at the endpoint of integration (pole) which is not physically realistic. Here the authors will only look at 10-year means of the AMIP runs, and for simplicity they assume that any long term imbalance in the global averaged N sfc will be sequestered (or released) over the global ocean. Tests have demonstrated that the treatment of how the global average energy imbalance is assumed to be distributed is important, especially when the long term imbalances are in excess of 10 W m -2 . However, this has not had a substantial impact on the qualitative features of the implied heat transport of the AMIP simulations examined thus far

    The energy situation in Egypt is characterized by a rather high energy demand, a high annual increase in energy consumption, inefficient utilization of energy, and heavily subsidized energy prices. Energy efficiency is therefore considered to be a matter of top priority, as it would lead to substantial savings. A national policy for efficient use of energy in industry has been outlined, including the establishment of an Industrial Energy Conservation Centre (IECC), the training and upgrading of energy management specialists, and the introduction of energy efficiency technologies in industrial plants. In this article the assistance that international organizations and donors can give to energy efficiency programmes is demonstrated. The results obtained so far are discussed and the lessons, findings and experience gained are outlined. (author). 1 tab

    The Alaskan and product market factors influencing industry locations in the state are discussed and a survey of the most energy intensive industries was made. Factors external to Alaska that would influence development and the cost of energy and labor in Alaska are analyzed. Industries that are likely to be drawn to Alaska because of its energy resources are analyzed in terms of: the cost of using Alaska energy resources in Alaska as opposed to the Lower 48; skill-adjusted wage and salary differentials between relevant Alaskan areas and the Lower 48; and basic plant and equipment and other operating cost differentials between relevant Alaskan areas and the Lower 48. Screening and evaluation of the aluminum metal industry, cement industry, chlor-alkali industry, lime industry, production of methanol from coal, petroleum refining, and production of petrochemicals and agrichemicals from North Slope natural gas for development are made.

    The current state and the future of the Dutch petrochemical industry are discussed. First, its current energy use, technology and its markets are analysed. Competitiveness of Dutch and Western European producers compared to foreign producers is shown. Main technological developments and other key issues (e.g. environmental issues) are discussed. Based on this analysis, a future scenario is derived for petrochemical industrial energy use for the period 2000-2015. This case study can be divided into an analysis of the current situation (Chapter 2-6) and alternatives for production and energy consumption of the Dutch petrochemical industry within its Western European context (Chapter 7-11). Chapter 2 analyses the current production structure and the historical developments. Chapter 3 discusses current technologies. Chapter 4 analyses markets for Dutch petrochemical products. Chapter 5 analyses the industry economics in the Netherlands in terms of costs and revenues. Chapter 6 provides information on institutional factors that influence industrial activities. Chapter 7 discusses global competition with special emphasis on competition for the European market. Chapter 8 analyses potential technology shifts. In Chapter 9, data from the preceding chapters on markets, competition, structure and technology are combined to compare competing production options. This is followed by a sensitivity analysis in Chapter 10. Based on a production volume forecast and the development of energy intensity of production, energy consumption of the Dutch petrochemical industry is forecast in Chapter 11. Finally, Chapter 12 provides conclusions and policy recommendations. 24 figs., 48 tabs., 103 refs., 2 appendices

    The rising costs of energy and the risks of uncertain energy supplies are increasingly familiar problems in industry. Bottom line profits and even the simple ability to operate can be affected by spiralling energy costs. An often overlooked alternative is the potential to turn industrial waste or residue into an energy source. On April 9 and 10, 1979, in Claremont, California, the Solar Energy Research Institute (SERI), the California Energy Commission (CEC), and the Western Solar Utilization Network (WSUN) held a workshop which provided industrial managers with current information on using residues and wastes as industrial energy sources. Successful industrial experiences were described by managers from the food processing and forest product industries, and direct combustion and low-Btu gasification equipment was described in detail. These speakers' presentations are contained in this document. Some major conclusions of the conference were: numerous current industrial applications of wastes and residues as fuels are economic and reliable; off-the-shelf technologies exist for converting biomass wastes and residues to energy; a variety of financial (tax credits) and institutional (PUC rate structures) incentives can help make these waste-to-energy projects more attractive to industry. However, many of these incentives are still being developed and their precise impact must be evaluated on a case-by-case basis.

    Societies before the Industrial Revolution were dependent on the annual cycle of plant photosynthesis for both heat and mechanical energy. The quantity of energy available each year was therefore limited, and economic growth was necessarily constrained. In the Industrial Revolution, energy usage increased massively and output rose accordingly. The energy source continued to be plant photosynthesis, but accumulated over a geological age in the form of coal. This poses a problem for the future. Fossil fuels are a depleting stock, whereas in pre-industrial time the energy source, though limited, was renewed each year.

    Renewable energy (RE) integration in the industry is already widespread worldwide. Beyond GHG emissions reduction, it brings direct operational, economical and non-financial benefits to industrial players in a changing energy environment. ENEA Consulting published the results of a study on the integration of RE in the industry conducted in partnership with Kerdos Energy for the International Energy Agency Renewable Energy Technology Deployment (IEA-RETD) who operates under the legal framework of the International Energy Agency. This study aims to provide inspiration and state-of-the-art applications of RE in the industry (identification of more than 200 projects worldwide), present best practices and key developments of such projects for industrial players (21 detailed case studies); and formulate policy recommendations for policy makers and provide lessons learned for industrial actors to make RE integration a widespread practice in the industry globally. Different integration schemes are possible, from simple and investment-light projects to more complex integration projects which can lead to core production processes adaptation. RE integration in industrial assets brings direct benefits to industrial players to better operate their assets, such as energy costs reduction and energy prices hedging, and improved energy supply reliability. Nevertheless, various barriers still hinder full RE development in the industry. However, industrial players and policy makers have a wide array of options to overcome them. Eight issues have been identified that can tilt an industrial actor towards or away from deploying RE production assets in its facilities. Thus, third party energy production schemes represent a significant opportunity for industrial players who lack the equity capital / cash needed to develop RE projects. Similarly, new shorter-term contractual schemes that fit better with industrial players' and third party energy producers' constraints are being developed

    The German shipping industry pays much attention to sustainability and efficiency. More strict international environmental requirements often encourage shipping companies to incite shipbuilders towards innovation. Yet some shipbuilders are consciously adopting a frontrunner's role in developing prototypes of energy efficient ships. In addition to the return of modern versions of sailing ships these projects also entail hydrogen, wind energy and new materials, but also exploring the ocean with satellites to gather detailed information used for optimizing the itinerary.

Naast de terugkeer van moderne versies van zeilschepen gaat het hierbij om projecten met waterstof, windenergie en nieuwe materialen, maar ook om het verkennen van de oceaan met satellieten om nauwkeurige gegevens te vergaren voor de optimalisatie van vaarroutes.

    Despite a long-term decline in the circus industry, Cirque du Soleil profitably increased revenue 22-fold over the last ten years by reinventing the circus. Rather than competing within the confines of the existing industry or trying to steal customers from rivals, Cirque developed uncontested market space that made the competition irrelevant. Cirque created what the authors call a blue ocean, a previously unknown market space. In blue oceans, demand is created rather than fought over. There is ample opportunity for growth that is both profitable and rapid. In red oceans--that is, in all the industries already existing--companies compete by grabbing for a greater share of limited demand. As the market space gets more crowded, prospects for profits and growth decline. Products turn into commodities, and increasing competition turns the water bloody. There are two ways to create blue oceans. One is to launch completely new industries, as eBay did with online auctions. But it's much more common for a blue ocean to be created from within a red ocean when a company expands the boundaries of an existing industry. In studying more than 150 blue ocean creations in over 30 industries, the authors observed that the traditional units of strategic analysis--company and industry--are of limited use in explaining how and why blue oceans are created. The most appropriate unit of analysis is the strategic move, the set of managerial actions and decisions involved in making a major market-creating business offering. Creating blue oceans builds brands. So powerful is blue ocean strategy, in fact, that a blue ocean strategic move can create brand equity that lasts for decades.

  9. Navigating a sea of values: Understanding public attitudes toward the ocean and ocean energy resources

    Lilley, Jonathan Charles

    In examining ocean values and beliefs, this study investigates the moral and ethical aspects of the relationships that exist between humans and the marine environment. In short, this dissertation explores what the American public thinks of the ocean. The study places a specific focus upon attitudes to ocean energy development. Using both qualitative and quantitative methods, this research: elicits mental models that exist in society regarding the ocean; unearths what philosophies underpin people's attitudes toward the ocean and offshore energy development; assesses whether these views have any bearing on pro-environmental behavior; and gauges support for offshore drilling and offshore wind development. Despite the fact that the ocean is frequently ranked as a second-tier environmental issue, Americans are concerned about the state of the marine environment. Additionally, the data show that lack of knowledge, rather than apathy, prevents people from undertaking pro-environmental action. With regard to philosophical beliefs, Americans hold slightly more nonanthropocentric than anthropocentric views toward the environment. Neither anthropocentrism nor nonanthropocentrism has any real impact on pro-environmental behavior, although nonanthropocentric attitudes reduce support for offshore wind. This research also uncovers two gaps between scientific and public perceptions of offshore wind power with respect to: 1) overall environmental effects; and 2) the size of the resource. Providing better information to the public in the first area may lead to a shift toward offshore wind support among opponents with nonanthropocentric attitudes, and in both areas, is likely to increase offshore wind support.

    1983-03-01

    Falling oil prices and conservation measures have reduced the economic impetus to develop new energy sources, thus decreasing the urgency for bringing solar conversion technologies to commercial readiness at an early date. However, the capability for solar to deliver thermal energy for industrial uses is proven. A year-round operation would be three times as effective as home heating, which is necessary only part of the year. Flat plate, parabolic trough, and solar tower power plant demonstration projects, though uneconomically operated, have revealed engineering factors necessary for successful use of solar-derived heat for industrial applications. Areas of concern have been categorized as technology comparisons, load temperatures, plant size, location, end-use, backup requirements, and storage costs. Tax incentives have, however, supported home heating and not industrial uses, and government subsidies have historically gone to conventional energy sources. Tax credit programs which could lead to a 20% market penetration by solar energy in the industrial sector by the year 2000 are presented.

    Industry contributes directly and indirectly (through consumed electricity) about 37% of the global greenhouse gas emissions, of which over 80% is from energy use. Total energy-related emissions, which were 9.9 GtCO2 in 2004, have grown by 65% since 1971. Even so, industry has almost continuously improved its energy efficiency over the past decades. In the near future, energy efficiency is potentially the most important and cost-effective means for mitigating greenhouse gas emissions from industry. This paper discusses the potential contribution of industrial energy efficiency technologies and policies to reduce energy use and greenhouse gas emissions to 2030.

    Full Text Available Harvesting marine renewable energy remains to be a prime focus of researchers across the globe both in environmental and in commercial perspectives. India is blessed with a long coastline, and the seas around Indian peninsula offer ample potential to tap various ocean energy forms. National Institute of Ocean Technology carries out research and various ocean energy technologies, out of which harnessing kinetic energy in seawater currents is one. This article presents the open sea trials recently carried out on National Institute of Ocean Technology’s cross-flow hydrokinetic ocean current turbine in South Andaman. The turbine was designed to generate 100 W electricity at 1.2 m/s current speed and was built in-house. The turbine was initially tested in a seawater channel and then was deployed in Macpherson Strait in Andaman. It was fitted below a floating platform designed especially for this purpose, and the performance of the turbine was continuously logged inside an on-board data acquisition system. The trials were successful and in line with computations.

    U.S. industry consumes approximately 37 percent of the nation's energy to produce 24 percent of the nation's GDP. Increasingly, industry is confronted with the challenge of moving toward a cleaner, more sustainable path of production and consumption, while increasing global competitiveness. Technology will be essential for meeting these challenges. At some point, businesses are faced with investment in new capital stock. At this decision point, new and emerging technologies compete for capital investment alongside more established or mature technologies. Understanding the dynamics of the decision-making process is important to perceive what drives technology change and the overall effect on industrial energy use. The assessment of emerging energy-efficient industrial technologies can be useful for: (1) identifying R&D projects; (2) identifying potential technologies for market transformation activities; (3) providing common information on technologies to a broad audience of policy-makers; and (4) offering new insights into technology development and energy efficiency potentials. With the support of PG&E Co., NYSERDA, DOE, EPA, NEEA, and the Iowa Energy Center, staff from LBNL and ACEEE produced this assessment of emerging energy-efficient industrial technologies. The goal was to collect information on a broad array of potentially significant emerging energy-efficient industrial technologies and carefully characterize a sub-group of approximately 50 key technologies. Our use of the term ''emerging'' denotes technologies that are both pre-commercial but near commercialization, and technologies that have already entered the market but have less than 5 percent of current market share. We also have chosen technologies that are energy-efficient (i.e., use less energy than existing technologies and practices to produce the same product), and may have additional ''non-energy benefits.'' These benefits are as important (if

    The food industry in Taiwan is labor intensive, the cost of raw materials is high, and there is much product diversification. Although this industry is primarily small and medium scale, it is a large user of electricity in Taiwan's manufacturing sector. The concentration of greenhouse gases (GHGs) from manufacturing activities and vehicle emissions has increased remarkably. Energy audits are a basic and direct means by which energy efficiency can be improved, energy consumption reduced, and carbon dioxide emissions inhibited. This work summarizes the energy saving potential of 76 firms and the energy savings implemented by 23 firms as determined by energy audit tracking and from the on-line energy declaration system in Taiwan's food industry. The results of this study can serve as a benchmark for developing a quantified list in terms of potential energy savings and opportunities for improving the efficiency of the food industry. - Highlights: ► This work summarizes the energy saving potential and the energy savings implemented in food industry. ► The results of this study can serve as a benchmark for developing a quantified list in terms of potential energy savings. ► The opportunities for improving the efficiency of the food industry can be a reference.

    Full Text Available In the intensifying condition of economic situation and increasing competitiveness in domestic and foreign markets, the most important way to develop competitive ability of an industrial company is to reduce energy costs in the production process. Insufficient level of the efficiency of energy resources usage affects an industrial company’s performance indicators and its investment attractiveness. A promising way of solving this matter is to develop and implement a strategy of rational energy consumption, which is aimed at the realization of company’s potential to optimize the consumption of electric energy by using internal and external resources in order to minimize energy costs. The strategy of rational energy consumption defines how an industrial company acquires electric energy and uses it to sustain the production. While developing and implementing the strategy, one should use a systemic and complex way and consider the following: peculiarities of electric energy and power as products; the structure of electric energy market and the possibilities of its consumers; peculiarities of price-formation on electric energy market; technical and technological, organizational and administrative, social and economic parameters of a company, characteristic features of its resource potential and production processes; the results of company’s energy efficiency audit and energy problems; company’s reserves that can increase its energy efficiency. An integral strategy of energy consumption includes a strategy for energy preservation and efficiency and a strategy for energy costs management. Both strategies are interrelated and serve for one purpose, which is minimizing the energy costs. This division helps simplify the analysis, search for alternatives and realization of energy management on operative, tactical and strategic levels, considering the regional and industry-specific peculiarities of an industrial company, its financial performance and

    Current and future energy demands, end uses, and cost used to characterize typical applications and resultant services in the industrial sector of the United States and 15 selected states are examined. A review and evaluation of existing industrial energy data bases was undertaken to assess their potential for supporting SERI research on: (1) market suitability analysis, (2) market development, (3) end-use matching, (3) industrial applications case studies, and (4) identification of cost and performance goals for solar systems and typical information requirements for industrial energy end use. In reviewing existing industrial energy data bases, the level of detail, disaggregation, and primary sources of information were examined. The focus was on fuels and electric energy used for heat and power purchased by the manufacturing subsector and listed by 2-, 3-, and 4-digit SIC, primary fuel, and end use. Projections of state level energy prices to 1990 are developed using the energy intensity approach. The effects of federal and state industrial energy conservation programs on future industrial sector demands were assessed. Future end-use energy requirements were developed for each 4-digit SIC industry and were grouped as follows: (1) hot water, (2) steam (212 to 300/sup 0/F, each 100/sup 0/F interval from 300 to 1000/sup 0/F, and greater than 1000/sup 0/F), and (3) hot air (100/sup 0/F intervals). Volume I details the activities performed in this effort.

    Full Text Available Environmental friendly renewable energy plays an indispensable role in energy industry development. Foreign direct investment (FDI in advanced renewable energy technology spillover is promising to improve technological capability and promote China’s energy industry performance growth. In this paper, the impacts of FDI renewable energy technology spillover on China’s energy industry performance are analyzed based on theoretical and empirical studies. Firstly, three hypotheses are proposed to illustrate the relationships between FDI renewable energy technology spillover and three energy industry performances including economic, environmental, and innovative performances. To verify the hypotheses, techniques including factor analysis and data envelopment analysis (DEA are employed to quantify the FDI renewable energy technology spillover and the energy industry performance of China, respectively. Furthermore, a panel data regression model is proposed to measure the impacts of FDI renewable energy technology spillover on China’s energy industry performance. Finally, energy industries of 30 different provinces in China based on the yearbook data from 2005 to 2011 are comparatively analyzed for evaluating the impacts through the empirical research. The results demonstrate that FDI renewable energy technology spillover has positive impacts on China’s energy industry performance. It can also be found that the technology spillover effects are more obvious in economic and technological developed regions. Finally, four suggestions are provided to enhance energy industry performance and promote renewable energy technology spillover in China.

German industry suffers not only from high wage and on-cost but high, energy costs as well. Waste disposal problems and impending taxes on wages are the cause of these difficulties. The EC believes that competition between energy supplies may help to reduce energy costs. This report deals with cost-efficient energy supply for the German industry and books at the background of this scenario. This industry puts forward its wishes and demands to politicians and energy economy. Representatives of energy suppliers discuss energy supplies, demand, availability, safety of supplies, competitiveness, quality and environmental aspects. The influence of energy costs and environmental taxation on the industrial and economic future of Germany and the situation in the Eastern States of Germany are a further subject of discussion. The views of the EC commission, the industry and the energy suppliers on energy transports across the EC are discussed as well. (orig./UA) [de

    A voluntary industrial energy-conservation program was initiated and now includes 50 trade organizations representing over 3,000 companies. Their current reporting system is an effort to respond to the Energy Policy and Conservation Act requirements, as now modified by the National Energy Conservation Policy Act. DOE's Office of Industrial Programs held six workshops in various key locations between November 1978 and February 1979 to enable energy managers to develop ideas and make suggestions that would improve the current and future energy-reporting programs. This report is a summary of the wide range of recommendations that the workshop participants offered as a means of meeting the NECPA requirements and the criticism of the current reporting program. It also reflects industry's views on potential approaches to future reporting. (MCW)

    1984-08-01

    The New Industrial Park Energy Supply (NIPES) concept allows the use of coal by small as well as large industrial users. The NIPES concept consists of a system of Energy Supply Stations groups of cogeneration plants) and steam transmission lines that supplies process heat and electricity to multiple existing and/or new users in an industrial park(s) setting. The Energy Supply Stations grow along with the industrial park(s) as new industries are attracted by a reliable reasonably priced energy source. The growth of the Energy Supply Stations over a period of years allows the introduction of new energy sources and technologies as they become established. This report describes the generic NIPES concept and the results of the evaluation of a specific NIPES system for the Lake Charles, Louisiana, area. A ten-year process steam load growth scenario is developed including both new and existing industrial users. During the initial years of the growth scenario, process steam is supplied to the industrial users by several coal-fired plants. Later, as the process steam load develops, a two-unit nuclear plant is integrated into the specific NIPES system. An evaluation is also performed for a NIPES system consisting of all coal-fired plants. The specific NIPES system is compared to: (1) individual user owned oil-fired facilities for existing industrial users; and (2) individual user owned coal-fired facilities for new industrial plants. A financial analysis is performed to determine the total economic advantages associated with the NIPES system: savings in a steam costs for industrial users, potential return on investment for investors

    About 37% of the primary energy consumed both in the U.S. and globally is used by the industrial sector. A variety of energy efficiency policies and programs have been implemented throughout the world in an effort to improve the energy efficiency of this sector. This report provides an overview of these policies and programs in twelve industrialized nations and the European Union (EU). We focus on energy efficiency products and services that are available to industrial consumers, such as reports, guidebooks, case studies, fact sheets, profiles, tools, demonstrations, roadmaps and benchmarking. We also focus on the mechanisms to communicate the availability and features of these products and services and to disseminate them to the industrial consumers who can use them. Communication channels include customer information centers and websites, conferences and trade shows, workshops and other training mechanisms, financial assistance programs, negotiated agreements, newsletters, publicity, assessments, tax and subsidy schemes and working groups. In total, over 30 types of industrial sector energy efficiency products, services and delivery channels have been identified in the countries studied. Overall, we found that the United States has a large variety of programs and offers industry a number of supporting programs for improving industrial energy efficiency. However, there are some products and services found in other industrialized countries that are not currently used in the U.S., including benchmarking programs, demonstration of commercialized technologies and provision of energy awareness promotion materials to companies. Delivery mechanisms found in other industrialized countries that are not employed in the U.S. include negotiated agreements, public disclosure and national-level tax abatement for energy-efficient technologies.

    1979-06-01

    Ocean Thermal Energy Conversion (OTEC), an attractive alternative to traditional energy sources, is still in the early stages of development. To facilitate OTEC commercialization, it is essential that a legal and institutional framework be designed now so as to resolve uncertainties related to OTEC development, primarily involving jurisdictional, regulatory, and environmental issues. The jurisdictional issues raised by OTEC use are dependent upon the site of an OTEC facility and its configuration; i.e., whether the plant is a semipermanent fixture located offshore or a migrating plant ship that provides a source of energy for industry at sea. These issues primarily involve the division of authority between the Federal Government and the individual coastal states. The regulatory issues raised are largely speculative: they involve the adaptation of existing mechanisms to OTEC operation. Finally, the environmental issues raised center around compliance with the National Environmental Policy Act (NEPA) as well as international agreements. 288 references.

  9. Measuring industrial energy savings

    International Nuclear Information System (INIS)

    Kelly Kissock, J.; Eger, Carl

    2008-01-01

    Accurate measurement of energy savings from industrial energy efficiency projects can reduce uncertainty about the efficacy of the projects, guide the selection of future projects, improve future estimates of expected savings, promote financing of energy efficiency projects through shared-savings agreements, and improve utilization of capital resources. Many efforts to measure industrial energy savings, or simply track progress toward efficiency goals, have had difficulty incorporating changing weather and production, which are frequently major drivers of plant energy use. This paper presents a general method for measuring plant-wide industrial energy savings that takes into account changing weather and production between the pre and post-retrofit periods. In addition, the method can disaggregate savings into components, which provides additional resolution for understanding the effectiveness of individual projects when several projects are implemented together. The method uses multivariable piece-wise regression models to characterize baseline energy use, and disaggregates savings by taking the total derivative of the energy use equation. Although the method incorporates search techniques, multi-variable least-squares regression and calculus, it is easily implemented using data analysis software, and can use readily available temperature, production and utility billing data. This is important, since more complicated methods may be too complex for widespread use. The method is demonstrated using case studies of actual energy assessments. The case studies demonstrate the importance of adjusting for weather and production between the pre- and post-retrofit periods, how plant-wide savings can be disaggregated to evaluate the effectiveness of individual retrofits, how the method can identify the time-dependence of savings, and limitations of engineering models when used to estimate future savings

    A study is made to show the current technological levels in Japan and other nations regarding the conversion of tidal current or ocean current energy to electric power and to determine the latent energy quantities and energy-related characteristics of tidal and ocean currents. In Japan, relatively large-scale experiments made so far mostly used one of the following three types of devices: Savonius-wheel type, Darrieus-wheel type, and cross-flow-wheel type. Field experiments of tidal energy conversion have been performed at the Naruto and Kurushima Straits. The energy in the Kuroshio current is estimated at about 170 billion kWh per year. Ocean current energy does not undergo large seasonal variations. The total energy in major straits and channels in the Inland Sea and other sea areas to the west is estimated at about 124 billion kWh per year. Tidal current energy shows large seasonal variations, but it is possible to predict the changes. A survey is made to determine energy-related characteristics of a tidal current at Chichino-seto, Kagoshima Prefecture. At Chichino-seto, the flow velocity ranges from 0 to 2.2m/s, with a latent tidal current energy of about 70 kW, of which about 20 kW can actually be utilized.

    A survey was conducted to find the level of energy consumption in the food manufacturing industry, which is the food processing industry excluding meat, dairy, and brewing. Data were used from 74 factories. The manufacturing industry was divided into 14 industry groups and the 4 major energy consumers were found to be fruit and vegetable processing, sugar refining, animal feed production, and bread and pastry baking. The present report summarizes results from the survey. It determined the following: the sources of energy used by the insu industry and the annual consumption of each energy form; the consumption of fuel and electricity in the production of the various manufactured food products; the minimum practical energy requirement for processing the various food products; and the potential for conservation and the methods for achieving savings.

  14. The impact of energy prices on industrial energy efficiency and productivity

    International Nuclear Information System (INIS)

    Boyd, G.A.

    1993-01-01

    Energy prices moved into the forefront of concern in the mid and late seventies when two oil price shocks drove up energy prices dramatically. The analysis of the subsequent increase in industrial energy efficiency, i.e., decline in energy use per unit of industrial output, has filled volumes of government and private studies. Despite the volumes of analysis, there remains no consensus on the magnitude of the effect of energy prices on industrial energy efficiency or the effect of the change in energy prices on productivity. This paper examines some sources of the controversy to initiate a dialog between policy makers, analysts, and the energy consumers and producers

  15. Energy and economic growth in industrializing countries

    Energy Technology Data Exchange (ETDEWEB)

    Samouilidis, J E; Mitropoulos, C S

    1984-07-01

    This paper investigates some aspects of the interrelated paths of economic growth and energy demand, in the case of an industrializing economy, through the use of numerous econometric models. Translog functions have helped establish that income and price elasticities of energy, two critical parameters in the energy-economy interaction, exhibit falling trends with time. The value share of the industrial sector is strongly associated with both energy demand and energy intensity. Any increase in the former will lead to amplified increases in the latter, rendering the continuation of past trends in industrial expansion questionable under conditions of high energy costs. Substitution among capital, labor and energy does take place, though to a limited extent, as indicated by the aggregate measure of energy/non-energy substitution elasticity. All findings appear to suggest that energy policymaking, in an industrializing country like Greece, will be of low effectiveness until certain structural changes in the economy are realized.

    The European renewable energy industry has the potential to be a world leader. This has been achieved within the European region for specific technologies, through a set of policy activities at a national and regional level, driven primarily by employment, energy self-sufficiency and industrial competitiveness. Using the experience gained in recent years, European industry has the opportunity to continue to expand its horizons on a worldwide level. Through the use of the SAFIRE rational energy model, an assessment has been made of the future penetration of renewable energy within Europe and the effects on these socio-economic factors. In conjunction with these outputs, assessments of the worldwide markets for wind, photovoltaics, solar thermal plant and biomass have been assessed. A case study of the Danish wind industry is used as a prime example of a success story from which the learning opportunities are replicated to other industries, so that the European renewable energy industry can achieve its potential.

    The knitting industry includes organizations concerned with hosiery, other weft knitted goods and warp-knitting and in some cases also with subsequent dyeing and finishing of knitted goods. In 1976, the industry had 116,000 employees located at approximately 600 sites, mostly in the East Midlands. The total energy consumption of the industry in 1976 was estimated to be 12,180 TJ. Sites with dyeing and finishing interests could save 15% of their energy. The major sources of savings (6%) are by recovering process heat which is currently wasted and from better process control. Other significant savings (5%) are possible from better control, maintenance and insulation of boilers and pipes. Attention to better housekeeping, to controlling draughts and to space heating generally could account for a further 3.5% saving in energy. Sites without dyeing and finishing interests could save 13% of the total energy used by this group. The most important opportunities are better control of space heating (5.5%) and better control and insulation of boilers, pipes and services (5%). These sites have fewer opportunities to recover heat from processes (2%) than where dyeing and finishing takes place but opportunities do exist.

    With about 71% of the earth's surface covered with oceans, could 'blue coal' constitute our biggest and surest source of energy? Some day, perhaps. But there's still much to do. There are four major categories of these energies: - tidal power; - wave power; - marine current power; - ocean thermal energy conversion, linked to the circulation of water bodies of different temperatures. Two other types of energies may be added to these: algae power, which is more of a specific form of marine agriculture, and osmotic power, which takes advantage of salinity. With its 24 turbines and installed generating capacity of 240 MW, the venerable Rance tidal power plant on the northern coast of Brittany is still both the oldest and most powerful in the world today. But like all dams, the Rance dam has affected the balance of the ecosystem, including silting up of the estuary and impacts on fish and bird life. These concerns have the British, among others, hesitating to launch an ambitious project for a giant tidal power plant with 216 turbines and 8.6 GW of installed generating capacity in Severn, Scotland. Wave energy yet to be demonstrated Powering an electric generator with the movement of the waves is an attractive idea and there is no lack of projects, but many will be left behind on the strand. There are two ways to capture the energy of the waves. Oscillating systems are one of them. Equipped with pneumatic or hydraulic cylinders and installed on buoys, these wave-activated systems transmit their energy to a generator. Other cylinder systems installed on manmade dikes are activated by the undertow. There are also ocean swell capture systems below the sea floor that send drive land-based turbines. All of these concepts are under development, but none has truly been demonstrated. A marine transposition of onshore and offshore wind turbines, marine current turbines are more conventional. Since water is 800 times denser than air, weak currents (about 3 meters per second) are

    This paper examines how energy efficiency fails in the building industry based on many years of research into the integration of energy efficiency in the construction of buildings and sustainable architecture in Norway. It argues that energy-efficient construction has been seriously restrained by three interrelated problems: (1) deficiencies in public policy to stimulate energy efficiency, (2) limited governmental efforts to regulate the building industry, and (3) a conservative building industry. The paper concludes that innovation and implementation of new, energy-efficient technologies in the building industry requires new policies, better regulations and reformed practices in the industry itself

    The aim of this study is to achieve greater output by examining the existing way of coordinating the determined attempts of Steam Industries in South Africa to successfully reach a sustainable industrial development by using energy source adequately in a more competent way. Furthermore into the study we look at obstacles that prevent and those that leads to maximum utilization of energy management measures and also highlights the effects of implementing cheap available energy source in South Africa. The investigation and analysis have shown that energy is not well managed in Steam Industries and that the use of energy is minimized and not fully utilized due to poor management and lack of knowledge. Another detection was that lack of government structured and strategic measures of implementing and motivating the use of energy effectively. The effective and rational use of available power by Steam Industries in South Africa is a key player in developing a sustainable industrial development. The use of energy efficiency management strategies has contributed an increase in economic and improve environmentally friendly in the industrial sector. The slow pace adoption of energy saving and cost effective management programmes are negatively impacting on the benefits to Steam Industries in South Africa. In conclusion the study finds that the economy can be boosted by implementing energy efficiency management programmes and environmentally friendly. These will also stabilize the negative impact of energy raising prices.

  8. Indicators for industrial energy efficiency in India

    India accounts for 4.5% of industrial energy use worldwide. This share is projected to increase as the economy expands rapidly. The level of industrial energy efficiency in India varies widely. Certain sectors, such as cement, are relatively efficient, while others, such as pulp and paper, are relatively inefficient. Future energy efficiency efforts should focus on direct reduced iron, pulp and paper and small-scale cement kilns because the potentials for improvement are important in both percentage and absolute terms. Under business as usual, industrial energy use is projected to rise faster than total final energy use. A strong focus on energy efficiency can reduce this growth, but CO 2 emissions will still rise substantially. If more substantial CO 2 emissions reductions are to be achieved then energy efficiency will need to be combined with measures that reduce the carbon intensity of the industrial fuel mix.

    The ocean can be a strategic alternative for obtaining energy supplies, both from ocean waves as from sea currents and tides. Among these features, the power generation projects based on ocean currents are still under development. Generating energy from ocean can have great impact on the Brazilian energy grid, since Brazil has a vast coastline, with more than 9,000 km long, with potential for generating energy from ocean currents not fully estimated. This article presents a preliminary determination of the energy potential for power generation from ocean currents along the coast of Rio Grande do Sul, the southernmost state of Brazil, and also presents notes that contribute to the characterization of the system of ocean currents in the region. The data used were obtained in two areas near Tramandai, allowing the determination of velocities and directions of the currents on a seasonal basis. The maximum speeds obtained rarely exceed 0.750 m/s, while the average speeds do not exceed 0.200 m/s. A relationship with the prevailing winds in the region was identified. Unfortunately, the results do not allow optimism about the power generation from ocean currents on the southern coast of Brazil, at least over the continental shelf.

    A new challenge to reduce energy usage has emerged in Swedish industry because of increasing energy costs. Energy usage in the Swedish powder coating industry is about 525 GWh annually. This industry has a long and successful record of working towards reduced environmental impact. However, they have not given priority to energy saving investments. Electricity and LPG, for which end-user prices are predicted to increase by as much as 50 - 60% by 2020, are the main energy carriers used in the plants. This paper presents the results of two detailed industrial energy audits conducted with the aim of quantifying the energy efficiency potential for the Swedish powder coating industry. Energy auditing and pinch analysis methods were used to identify possible energy housekeeping measures and heat exchanging opportunities. The biggest users of energy within the plants are the cure oven, drying oven and pre-treatment units. The energy use reduction by the housekeeping measures is 8 - 19% and by thermal heat recovery an additional 8 - 13%. These measures result in an average energy cost saving of 25% and reduction of carbon dioxide emissions of 30%. The results indicate that the powder coating industry has a total energy efficiency potential of at least 20%

    Industrial operations in the United States account for some 37% of the nation's consumptions of energy. It has been estimated that this figure will increase to 50% by 1990 unless appropriate industrial energy conservation measures are adopted. However, such measures are difficult to implement in spite of the potential of various existing, emerging, and advanced technologies that can be applied to the problem. Specifically, the application of many industrial energy conservation measures entails high economic, technological, and institutional risks and uncertainties that constrain industries from adopting such measures. Accordingly, in 1975 the federal government started a program designed to mitigate these risks and uncertainties via government-industry partnership arrangements in the interests of national energy conservation. An important element of this program is the Industrial Energy Conservation Program in the Federal Department of Energy (DOE). In June 1980, DOE asked the National Materials Advisory Board, a unit of the National Academy of Sciences-National Research Council, to form a study committee to assess the effectiveness of the Industrial Energy Conservation Program. The committee concluded that federal support embodied in the DOE program, present and planned, is important to conserving additional industrial energy. However, the committee also concluded that the program needs various improvements in project selection and management and in transfer of results to industry. The committee's findings and recommendations and the results of the deliberation of the committee's three panels, a special report on heat and power, and a report on the visit by four members of the committee to Japan are presented.

    Industrial Gases Companies have been mastering Hydrogen production, distribution, safe handling and applications for several decades for a wide range of gas applications. This unique industrial background positioned these companies to play a key role in the emerging Hydrogen Energy market, which can rely, at early stage of development, on already existing infrastructure, logistics and technical know-how. Nevertheless, it is important to acknowledge that Hydrogen Energy raised specific challenges which are not totally addressed by industrial gas activities. The main difference is obviously in the final customer profile, which differs significantly from the qualified professional our industry is used to serve. A non professional end-user, operating with Hydrogen at home or on board of his family car, has to be served with intrinsically safe and user-friendly solutions that exceed by far the industrial specifications already in place. Another significant challenge is that we will need breakthroughs both in terms of products and infrastructure, with development time frame that may require several decades. The aim of this presentation is to review how a company like Air Liquide, worldwide leader already operating more than 200 large hydrogen production sites, is approaching this new Hydrogen Energy market, all along the complete supply chain from production to end-users. Our contributions to the analysis, understanding and deployment of this new Energy market, will be illustrated by the presentation of Air Liquide internal development's as well as our participation in several national and European projects.

    The U.S. chemical industry is the largest in the world, and responsible for about 11% of the U.S. industrial production measured as value added. It consumes approximately 20% of total industrial energy consumption in the U.S. (1994), and contributes in similar proportions to U.S. greenhouse gas emissions. Surprisingly, there is not much information on energy use and energy intensity in the chemical industry available in the public domain. This report provides detailed information on energy use and energy intensity for the major groups of energy-intensive chemical products. Ethylene production is the major product in terms of production volume of the petrochemical industry. The petrochemical industry (SIC 2869) produces a wide variety of products. However, most energy is used for a small number of intermediate compounds, of which ethylene is the most important one. Based on a detailed assessment we estimate fuel use for ethylene manufacture at 520 PJ (LHV), excluding feedstock use. Energy intensity is estimated at 26 GJ/tonne ethylene (LHV), excluding feedstocks.The nitrogenous fertilizer production is a very energy intensive industry, producing a variety of fertilizers and other nitrogen-compounds. Ammonia is the most important intermediate chemical compound, used as basis for almost all products. Fuel use is estimated at 268 PJ (excluding feedstocks) while 368 PJ natural gas is used as feedstock. Electricity consumption is estimated at 14 PJ. We estimate the energy intensity of ammonia manufacture at 39.3 GJ/tonne (including feedstocks, HHV) and 140 kWh/tonne, resulting in a specific primary energy consumption of 40.9 GJ/tonne (HHV), equivalent to 37.1 GJ/tonne (LHV). Excluding natural gas use for feedstocks the primary energy consumption is estimated at 16.7 GJ/tonne (LHV). The third most important product from an energy perspective is the production of chlorine and caustic soda. Chlorine is produced through electrolysis of a salt-solution. Chlorine production is

    Since 1989, the U.S. Department of Energy has sponsored the Energy Efficient Industrialized Housing research program (EEIH) to improve the energy efficiency of industrialized housing. Two research centers share responsibility for this program: The Center for Housing Innovation at the University of Oregon and the Florida Solar Energy Center, a research institute of the University of Central Florida. Additional funding is provided through the participation of private industry, state governments and utilities. The program is guided by a steering committee comprised of industry and government representatives. This report summarizes Fiscal Year (FY) 1990 activities and progress, and proposed activities for FY 1991 in Task 2.1 Design for Energy Efficiency. This task establishes a vision of energy conservation opportunities in critical regions, market segments, climate zones and manufacturing strategies significant to industrialized housing in the 21st Century. In early FY 1990, four problem statements were developed to define future housing demand scenarios inclusive of issues of energy efficiency, housing design and manufacturing. Literature surveys were completed to assess seven areas of influence for industrialized housing and energy conservation in the future. Fifty-five future trends were identified in computing and design process; manufacturing process; construction materials, components and systems; energy and environment; demographic context; economic context; and planning policy and regulatory context.

  16. Productivity benefits of industrial energy efficiency measures

    2004-08-30

    We review the relationship between energy efficiency improvement measures and productivity in industry. We review over 70 industrial case studies from widely available published databases, followed by an analysis of the representation of productivity benefits in energy modeling. We propose a method to include productivity benefits in the economic assessment of the potential for energy efficiency improvement. The case-study review suggests that energy efficiency investments can provide a significant boost to overall productivity within industry. If this relationship holds, the description of energy-efficient technologies as opportunities for larger productivity improvements has significant implications for conventional economic assessments. The paper explores the implications this change in perspective on the evaluation of energy-efficient technologies for a study of the iron and steel industry in the US. This examination shows that including productivity benefits explicitly in the modeling parameters would double the cost-effective potential for energy efficiency improvement, compared to an analysis excluding those benefits. We provide suggestions for future research in this important area.

    This state-of-science review sets out to provide an indicative assessment of enabling technologies for reducing UK industrial energy demand and carbon emissions to 2050. In the short term, i.e. the period that will rely on current or existing technologies, the road map and priorities are clear. A variety of available technologies will lead to energy demand reduction in industrial processes, boiler operation, compressed air usage, electric motor efficiency, heating and lighting, and ancillary uses such as transport. The prospects for the commercial exploitation of innovative technologies by the middle of the 21st century are more speculative. Emphasis is therefore placed on the range of technology assessment methods that are likely to provide policy makers with a guide to progress in the development of high-temperature processes, improved materials, process integration and intensification, and improved industrial process control and monitoring. Key among the appraisal methods applicable to the energy sector is thermodynamic analysis, making use of energy, exergy and 'exergoeconomic' techniques. Technical and economic barriers will limit the improvement potential to perhaps a 30% cut in industrial energy use, which would make a significant contribution to reducing energy demand and carbon emissions in UK industry. Non-technological drivers for, and barriers to, the take-up of innovative, low-carbon energy technologies for industry are also outlined

    This study develops and examines physical energy intensity indicators in five industrial sub-sectors-iron and steel, aluminum, textiles, paper, and cement-and investigates mitigation options for energy related CO 2 emissions (during 1991-2005). Decomposition analysis has been employed to separate the structural effect (share of different products in the sector) from pure intensity effect (efficiency increase through technical improvement) for each industry. The results show that the combined effect (considering both structural and intensity effects together) on both iron and steel and paper and pulp industries is negative while it is positive for aluminum and textiles. The intensity effect for all the industries, barring textiles, is negative showing improvement in energy efficiency; iron and steel in particular, has seen a decrease of 134 PJ in energy consumption owing to improvements in efficiency. However, energy intensity in textiles has risen by 47 PJ due to increased mechanization. Structural effect is positive in aluminum and iron and steel industries indicating a movement towards higher energy-intensive products. In the case of aluminum, positive structural effect dominates over negative intensive effect whereas negative intensive effect dominates iron and steel industry. The paper helps in designing policies for improving productivity and reduce energy consumption in India's manufacturing sector. - Highlights: → The study develops physical energy intensity indicators in industrial sub-sectors of India. → It identifies technological and other options for reduction in energy consumption. → The study quantifies savings in energy as well as CO 2 emissions. → The indicators are useful in examining structural changes.

    The need for alternative sources of energy has never been more urgent than it is today. At the very time International Energy Agency estimates that demand will increase 30% by 2030, fossil fuels (oil, gas and coal) are beginning to dwindle, as the need to counter global warming imposes limits on CO 2 emissions. In this context, DCNS has entered a new field of innovation and development: ocean energy. Having included marine renewable energy as an intrinsic part of its strategic growth plan, DCNS is the only industrial company in the world to invest in all four key technologies in this sector: - the tidal energy generated using underwater turbines known as 'tidal turbines',' which convert the energy of marine tidal streams into electricity; - the ocean thermal energy conversion (OTEC) technology that exploits the difference of temperature between the warm surface water of tropical oceans and the cold water found in the ocean depths to generate electrical power 24 hours a day, 35 days a year; - the offshore wind energy generated by offshore floating wind turbines; - the wave energy technology which operates on the principle of recovering energy from the ocean swell. With 400 years of expertise in shipbuilding and its in-depth understanding of the marine environment, DCNS is committed to playing a major role in the development of this new ocean industry.

    Highlights: ► We analyze the energy and exergy utilizations of the Jordanian SMEs industries. ► We developed an energy balance for the Jordanian SMEs industries. ► The low efficiencies values suggest that many opportunities for better industrial energy utilizations still exist. - Abstract: This study presents detailed analysis of the energy and exergy utilizations of the Jordanian Small-Medium Enterprises (SMEs) by considering the flows of energy and exergy through the main end uses in the Jordanian industrial sector. To achieve this purpose, a survey covering 180 facilities was conducted and energy consumption data was gathered to establish detailed end-use balance for the Jordanian industrial sector. The energy end-use balance provides a starting point to estimate the site and embodied energy and exergy efficiencies. The average site energy and exergy efficiencies of the Jordanian SMEs industries sector are estimated as 78.3% and 37.9% respectively, while the embodied energy and exergy efficiencies are estimated as 58.9% and 21.2% respectively. The low efficiencies values suggest that many opportunities for better industrial energy utilizations still exist.

    The most extensive action targeting the adoption of energy efficiency measures in small- and medium-sized manufacturing industries in Sweden over the past 15 years was project Highland. This paper presents an evaluation of the first part of this local industrial energy programme, which shows an adoption rate of more than 40% when both measures that have already been implemented and measures that are planned to be implemented are included. A comparison between this programme and another major ongoing programme for the Swedish energy-intensive industry indicates that the approach used in project Highland aimed at small- and medium-sized industries is an effective way to increase energy efficiency in the Swedish industry. The major barriers to energy efficiency among the firms were related to the low priority of the energy efficiency issue

    Problems of the regional energy supply industry touching directly the energy supply utilities (e.g. territorial reform, power prices) are discussed. In a survey on the overall energy situation in the FRG as seen by energy supply utilities, the following conclusions are drawn: 1) The electricity supply industry is in the favourite position to make the required structural changes by utilizing primary energy for generating electric power. It offers - via electric energy - an effective opportunity for substituting oil. 2) The electricity supply industry alone will be in a position to use nuclear energy during the next few decades. A decision in favour of nuclear energy must not be at disposal to make oneself momentarily politically popular. This indispensable decision results exclusively from our responsibility for the future of our national economy and thus our society. (orig./HP) [de

    The effects of energy devices on fish populations are not well-understood, and studying the interactions of fish with tidal and instream turbines is challenging. To address this problem, we have evaluated algorithms to automatically detect fish in underwater video and propose a semi-automated method for ocean and river energy device ecological monitoring. The key contributions of this work are the demonstration of a background subtraction algorithm (ViBE) that detected 87% of human-identified fish events and is suitable for use in a real-time system to reduce data volume, and the demonstration of a statistical model to classify detections as fish or not fish that achieved a correct classification rate of 85% overall and 92% for detections larger than 5 pixels. Specific recommendations for underwater video acquisition to better facilitate automated processing are given. The recommendations will help energy developers put effective monitoring systems in place, and could lead to a standard approach that simplifies the monitoring effort and advances the scientific understanding of the ecological impacts of ocean and river energy devices.

    Although it is widely recognized that reducing freshwater consumption is of critical importance, generating interest in industrial water reduction programs can be hindered for a variety of reasons. These include the low cost of water, greater focus on water use in other sectors such as the agriculture and residential sectors, high levels of unbilled and/or unregulated self-supplied water use in industry, and lack of water metering and tracking capabilities at industrial facilities. However, there are many additional components to the resource savings associated with reducing site water use beyond the water savings alone, such as reductions in energy consumption, greenhouse gas emissions, treatment chemicals, and impact on the local watershed. Understanding and quantifying these additional resource savings can expand the community of businesses, NGOs, government agencies, and researchers with a vested interest in water reduction. This paper will develop a methodology for evaluating the embedded energy consumption associated with water use at an industrial facility. The methodology developed will use available data and references to evaluate the energy consumption associated with water supply and wastewater treatment outside of a facility’s fence line for various water sources. It will also include a framework for evaluating the energy consumption associated with water use within a facility’s fence line. The methodology will develop a more complete picture of the total resource savings associated with water reduction efforts and allow industrial water reduction programs to assess the energy and CO2 savings associated with their efforts.

    2010-09-29

    The textile industry is one of the most complicated manufacturing industries because it is a fragmented and heterogeneous sector dominated by small and medium enterprises (SMEs). Energy is one of the main cost factors in the textile industry. Especially in times of high energy price volatility, improving energy efficiency should be a primary concern for textile plants. There are various energy-efficiency opportunities that exist in every textile plant, many of which are cost-effective. However, even cost-effective options often are not implemented in textile plants mostly because of limited information on how to implement energy-efficiency measures, especially given the fact that a majority of textile plants are categorized as SMEs and hence they have limited resources to acquire this information. Know-how on energy-efficiency technologies and practices should, therefore, be prepared and disseminated to textile plants. This guidebook provides information on energy-efficiency technologies and measures applicable to the textile industry. The guidebook includes case studies from textile plants around the world and includes energy savings and cost information when available. First, the guidebook gives a brief overview of the textile industry around the world, with an explanation of major textile processes. An analysis of the type and the share of energy used in different textile processes is also included in the guidebook. Subsequently, energy-efficiency improvement opportunities available within some of the major textile sub-sectors are given with a brief explanation of each measure. The conclusion includes a short section dedicated to highlighting a few emerging technologies in the textile industry as well as the potential for the use of renewable energy in the textile industry.

    This paper studied effects of yen appreciation on the Japanese economy and changes in energy demand when assuming the medium-term yen appreciation trend, and subjects in the energy industry. The paper also refers to the trend of the Asian material industry largely influencing the energy supply/demand, the risk hedge problem of the exchange, and international cooperation and business development of the energy industry. The energy industry is extremely high in public interest and is rice of the industry. Therefore, the development of the business has focused on the domestic market. However, such a recognition is forced to be changed by waves of the worldwide deregulation. Discussions on foreign/domestic price differences caused by high yen and a series of deregulation policy in the energy industry affected thereby may be concrete signs. The subject in the energy industry under the yen appreciation is that the energy industry will be close to common sense in general industrial circles and change to an industry which is strong and internationally competitive enough to brave the exchange variation. 101 refs., 104 figs., 31 tabs.

  13. Ocean thermal-energy conversion

    1983-03-01

    Ocean thermal-energy conversion (OTEC) is a novel 'alternative' energy technology that has created much interest in a number of countries; namely, the USA, Japan, France, Sweden, Holland, India and most recently, the UK. In particular, the first three of these have had programmes to develop the required technology. However, most interest has been centred in the USA, where the current hiatus in Federal funding provides a timely opportunity to assess progress. This paper offers a survey of the prevailing position there; outlining the outstanding technical and associated problems, and likely future developments. Non-USA programmes are only mentioned to contrast them with the American position. At present, it does not appear that OTEC plants will be commercially viable on a widespread basis even in the tropics. This is particularly true of the larger plants (400 MWe, MWe = megawatts of electrical energy, the final output of a power station) towards which the American programme is ultimately geared. There does seem to be a strong possibility that small OTEC plants, around 40 MWe or less, can be commercial in certain circumstances. This would be possible when one or, preferably, more of the following conditions are met: (i) where a land-based rather than 'at sea' plant is possible, (ii) where alternative energy supplies are at a premium, i.e. islands or regions without indigenous energy supplies, and (iii) where conditions are such that an OTEC plant could operate in conjunction with either or both an aquaculture or desalination plant.

  14. Energy management in the Canadian airline industry

    1982-09-01

    The purpose of this report was to outline the current status of the Canadian airline industry's energy performance and to outline energy management programs undertaken within the industry. The study also provides an aviation energy management information base developed through a comprehensive computer bibliographical review. A survey of the industry was undertaken, the results of which are incorporated in this report. The Canadian airline industry has recognized the importance of energy management and considerable measures have been introduced to become more energy efficient. The largest single contributor to improved productivity is the acquisition of energy efficient aircraft. Larger airlines in particular have implemented a number of conservation techniques to reduce fuel consumption. However, both large and small airlines would further benefit through incorporating techniques and programs described in the annotated bibliography in this study. Rising fuel prices and economic uncertainties will be contributing factors to a smaller average annual growth in fuel consumption during the 1980s. The lower consumption levels will also be a result of continuing energy conservation awareness, new technology improvements, and improvements in air traffic control. 98 refs., 4 figs., 6 tabs.

    2013-09-15

    Increasing energy consumption and depleting reserves of fossil fuels have resulted in growing interest in alternative renewable energy from the ocean. Ocean currents are an alternative source of clean energy due to their inherent reliability, persistence and sustainability. General ocean circulations exist in the form of large rotating ocean gyres, and feature extremely rapid current flow in the western boundaries due to the Coriolis Effect. The Gulf Stream system is formed by the western boundary current of the North Atlantic Ocean that flows along the east coastline of the United States, and therefore is of particular interest as a potential energy resource for the United States. This project created a national database of ocean current energy resources to help advance awareness and market penetration in ocean current energy resource assessment. The database, consisting of joint velocity magnitude and direction probability histograms, was created from data created by seven years of numerical model simulations. The accuracy of the database was evaluated by ORNL?s independent validation effort documented in a separate report. Estimates of the total theoretical power resource contained in the ocean currents were calculated utilizing two separate approaches. Firstly, the theoretical energy balance in the Gulf Stream system was examined using the two-dimensional ocean circulation equations based on the assumptions of the Stommel model for subtropical gyres with the quasi-geostrophic balance between pressure gradient, Coriolis force, wind stress and friction driving the circulation. Parameters including water depth, natural dissipation rate and wind stress are calibrated in the model so that the model can reproduce reasonable flow properties including volume flux and energy flux. To represent flow dissipation due to turbines additional turbine drag coefficient is formulated and included in the model. Secondly, to determine the reasonableness of the total power

    The pulp and paper industry is highly energy intensive. In view of the spiralling fuel prices and rising power costs, there is an urgent need to conserve energy through better management of various operations in the industry, from the optimal utilization of the forest residues to the shipment of the final product. The total energy concept, e.g., energy generation, distribution and utilization in Indian paper industry is discussed. The need for an energy audit is emphasized and the formats of energy reporting forms are included. Short and long term measures to be enforced to achieve energy savings in the pulp and paper mills are outlined. Some important energy conservation approaches are also discussed. Factors affecting energy efficiency in a pulp and paper mill are reviewed. Some areas where sustained R and D efforts should be focused to make the paper industry nearly self-sufficient in energy generation and utilization are also given. It is essential to have a National Energy Policy clearly defining achievable targets of energy conservation for industry. The Indian paper industry could advantageously form its own committee to review the operation of the various mills in the country and come out with concrete solutions for higher energy efficiency and more effective conservation of energy.

    Turkey is one of a number of countries who still lack a national management standard for energy. Industrial energy consumption accounts for 42% of Turkey's total energy consumption. With the help of a questionnaire and analytical framework, this paper investigates Industrial Energy Management Practice in Turkey and highlights significant bottlenecks and shortcomings of energy intensive industries in terms of energy management application. The survey was carried out as a multiple case study of the Turkish iron, steel, cement, paper, ceramics and textile industries. Outcomes of the questionnaire are evaluated according to the analytical framework which covers company characteristics, regulations, external relations of the companies and internal organizational conditions. After analyzing these elements on the basis of a minimum requirement list, it was found that only 22% of the surveyed companies actually practice corporate energy management in Turkey. The main barriers to proper energy management implementation were identified as lack of synergy between the stakeholders, the extent and scope of energy manager courses, and inadequate awareness of and lack of financial support for energy management activities. As a guideline to overcome present obstacles, a set of policy options are offered: strengthening and restructuring of legal and institutional frameworks, promotion of energy efficiency, education, training and capacity building and facilitating implementation of the international energy management standard ISO 50001. -- Highlights: ► Developing an analytical scheme to assess degree of Energy Management Application. ► Investigation of Energy Management Practices in Turkish Energy Intensive Industries. ► Analysis of challenges which hinder full implementation of energy management in Turkey. ► Presenting a set of essential policy options thought for all stakeholders.

    This paper combines engineering and social science approaches to enhance our understanding of industrial energy efficiency and broaden our perspective on policy making in Europe. Sustainable development demands new strategies, solutions, and policy-making approaches. Numerous studies of energy efficiency potential state that cost-effective energy efficiency technologies in industry are not always implemented for various reasons, such as lack of information, procedural impediments, and routines not favoring energy efficiency. Another reason for the efficiency gap is the existence of particular values, unsupportive of energy efficiency, in the dominant networks of a branch of trade. Analysis indicates that different sectors of rather closed communities have established their own tacit knowledge, perceived truths, and routines concerning energy efficiency measures. Actors in different industrial sectors highlight different barriers to energy efficiency and why cost-effective energy efficiency measures are not being implemented. The identified barriers can be problematized in relation to the social context to understand their existence and how to resolve them.

    Industrial energy management systems, which comprise software solutions, upfront services, and ongoing monitoring and management, enable industrial companies to actively manage their energy consumption and energy procurement activities. Energy management systems are usually tailored to the specific industrial needs but may offer limited functionalities, mostly as a result of different identified gaps (process simplifications, improper measurement points, a lack of motivation, etc.). A survey was conducted in order to analyse the gaps and use of energy management systems in Slovenian industry. The results of the survey presented in this paper demonstrate that the use of energy management systems in industry is recognised as a potential competitive advantage by most of the addressed companies. Furthermore, motivation was highlighted as an important prerequisite for process and structural improvements and reported to be thus far insufficiently addressed. Furthermore, the importance of strong cooperation with actors at different levels of industry, namely the executive and shop floor levels, is addressed. In the conclusion, possibilities for new opportunities in the exploitation of energy efficiency through the use of industrial energy management systems are discussed. - Highlights: • Investigating gaps and evaluation of EMS use in Slovenian industry. • Analysis based on the developed self-assessment tool 3EMT. • Existing EMS do not include all the requirements for the industrial operations. • Constructive cooperation between all stakeholders is of crucial importance.

    A stochastic optimization methodology is formulated for computing energy-optimal paths from among time-optimal paths of autonomous vehicles navigating in a dynamic flow field. To set up the energy optimization, the relative vehicle speed and headings are considered to be stochastic, and new stochastic Dynamically Orthogonal (DO) level-set equations that govern their stochastic time-optimal reachability fronts are derived. Their solution provides the distribution of time-optimal reachability fronts and corresponding distribution of time-optimal paths. An optimization is then performed on the vehicle's energy-time joint distribution to select the energy-optimal paths for each arrival time, among all stochastic time-optimal paths for that arrival time. The accuracy and efficiency of the DO level-set equations for solving the governing stochastic level-set reachability fronts are quantitatively assessed, including comparisons with independent semi-analytical solutions. Energy-optimal missions are studied in wind-driven barotropic quasi-geostrophic double-gyre circulations, and in realistic data-assimilative re-analyses of multiscale coastal ocean flows. The latter re-analyses are obtained from multi-resolution 2-way nested primitive-equation simulations of tidal-to-mesoscale dynamics in the Middle Atlantic Bight and Shelbreak Front region. The effects of tidal currents, strong wind events, coastal jets, and shelfbreak fronts on the energy-optimal paths are illustrated and quantified. Results showcase the opportunities for longer-duration missions that intelligently utilize the ocean environment to save energy, rigorously integrating ocean forecasting with optimal control of autonomous vehicles.

    Steam systems are a part of almost every major industrial process today. Thirty-seven percent of the fossil fuel burned in US industry is burned to produce steam. In this paper we will establish baseline energy consumption for steam systems. Based on a detailed analysis of boiler energy use we estimate current energy use in boilers in U.S. industry at 6.1 Quads (6.4 EJ), emitting almost 66 MtC in CO(sub 2) emissions. We will discuss fuels used and boiler size distribution. We also describe potential savings measures, and estimate the economic energy savings potential in U.S. industry (i.e. having payback period of 3 years or less). We estimate the nationwide economic potential, based on the evaluation of 16 individual measures in steam generation and distribution. The analysis excludes the efficient use of steam and increased heat recovery. Based on the analysis we estimate the economic potential at 18-20% of total boiler energy use, resulting in energy savings approximately 1120-1190 TBtu ( 1180-1260 PJ). This results in a reduction of CO(sub 2) emissions equivalent to 12-13 MtC

    The goal of direct drive ocean wave energy extraction system is to convert ocean wave energy into electricity. The problem explored in this paper is the design and optimal control for the direct drive ocean wave energy extraction system. An optimal control method based on internal model proportion integration differentiation (IM-PID) is proposed in this paper though most of ocean wave energy extraction systems are optimized by the structure, weight, and material. With this control method, the heavy speed of outer heavy buoy of the energy extraction system is in resonance with incident wave, and the system efficiency is largely improved. Validity of the proposed optimal control method is verified in both regular and irregular ocean waves, and it is shown that IM-PID control method is optimal in that it maximizes the energy conversion efficiency. In addition, the anti-interference ability of IM-PID control method has been assessed, and the results show that the IM-PID control method has good robustness, high precision, and strong anti-interference ability.

    Wind turbines continuously remove kinetic energy from the lower troposphere, thereby reducing the wind speed near hub height. The rate of electricity generation in large wind farms containing multiple wind arrays is, therefore, constrained by the rate of kinetic energy replenishment from the atmosphere above. In recent years, a growing body of research argues that the rate of generated power is limited to around 1.5 W m -2 within large wind farms. However, in this study, we show that considerably higher power generation rates may be sustainable over some open ocean areas. In particular, the North Atlantic is identified as a region where the downward transport of kinetic energy may sustain extraction rates of 6 W m -2 and above over large areas in the annual mean. Furthermore, our results indicate that the surface heat flux from the oceans to the atmosphere may play an important role in creating regions where sustained high rates of downward transport of kinetic energy and thus, high rates of kinetic energy extraction may be geophysical possible. While no commercial-scale deep water wind farms yet exist, our results suggest that such technologies, if they became technically and economically feasible, could potentially provide civilization-scale power.

    Industry accounts for about one-third of global energy demand. Most of that energy is used to produce raw materials: chemicals, iron and steel, non-metallic minerals, pulp and paper and non-ferrous metals. Just how efficiently is this energy put to work? This question was on the minds of the G8 leaders at their summit in Gleneagles in 2005, when they set a 'Plan of Action for Climate Change, Clean Energy and Sustainable Development'. They called upon the International Energy Agency to provide information and advice in a number of areas including special attention to the industrial sector. Tracking Industrial Energy Efficiency and CO2 Emissions responds to the G8 request. This major new analysis shows how industrial energy efficiency has improved dramatically over the last 25 years. Yet important opportunities for additional gains remain, which is evident when the efficiencies of different countries are compared. This analysis identifies the leaders and the laggards. It explains clearly a complex issue for non-experts. With new statistics, groundbreaking methodologies, thorough analysis and advice, and substantial industry consultation, this publication equips decision makers in the public and private sectors with the essential information that is needed to reshape energy use in manufacturing in a more sustainable manner.

    This report examines several different measures of industrial output for use in constructing estimates of industrial energy efficiency and discusses some reasons for differences between the measures. Estimates of volume-based measures of output, as well as 3 value-based measures of output (value of production, value of shipments, and value added), are evaluated for 15 separate 4-digit industries. Volatility, simple growth rate, and trend growth rate estimates are made for each industry and each measure of output. Correlations are made between the volume- and value-based measures of output. Historical energy use data are collected for 5 of the industries for making energy- intensity estimates. Growth rates in energy use, energy intensity, and correlations between volume- and value-based measures of energy intensity are computed. There is large variability in growth trend estimates both long term and from year to year. While there is a high correlation between volume- and value-based measures of output for a few industries, typically the correlation is low, and this is exacerbated for estimates of energy intensity. Analysis revealed reasons for these low correlations. It appears that substantial work must be done before reliable measures of trends in the energy efficiency of industry can be accurately characterized.

    The vertical thermal energy potential in the ocean is a massive renewable energy resource that is growing due to anthropogenic warming of the surface and near-surface ocean. The conversion of this thermal energy to useful forms via Ocean Thermal Energy Conversion (OTEC) has been demonstrated over the past century, albeit at small scales. Because OTEC removes heat from the surface ocean, this could help directly counter ongoing, deleterious ocean/atmosphere warming. The only other climate intervention that could do this is solar radiation "geoengineering". Conventional OTEC requires energy intensive, vertical movement of seawater resulting in ocean and atmospheric chemistry alteration, but this can be avoided via more energy efficient, vertical closed-cycle heating and cooling of working fluid like CO2 or NH3. An energy carrier such as H2 is required to transport energy optimally extracted far offshore, and methods of electrochemically generating H2 while also consuming CO2 and converting it to ocean alkalinity have been demonstrated. The addition of such alkalinity to the ocean would provide vast, stable, carbon storage, while also helping chemically counter the effects of ocean acidification. The process might currently be profitable given the >$100/tonne CO2 credit offered by California's Low Carbon Fuel Standard for transportation fuels like H2. Negative-Emissions OTEC, NEOTEC, thus can potentially provide constant, cost effective, high capacity, negative-emissions energy while: a) reducing surface ocean heat load, b) reducing thermal ocean expansion and sea-level rise, c) utilizing a very large, natural marine carbon storage reservoir, and d) helping mitigate ocean acidification. The technology also avoids the biophysical and land use limitations posed by negative emissions methods that rely on terrestrial biology, such as afforestation and BECCS. NEOTEC and other marine-based, renewable energy and CO2 removal approaches could therefore greatly increase the

  1. Anomaly transform methods based on total energy and ocean heat content norms for generating ocean dynamic disturbances for ensemble climate forecasts

    2017-08-01

    In our study we use the anomaly transform, a special case of ensemble transform method, in which a selected set of initial oceanic anomalies in space, time and variables are defined and orthogonalized. The resulting orthogonal perturbation patterns are designed such that they pick up typical balanced anomaly structures in space and time and between variables. The metric used to set up the eigen problem is taken either as the weighted total energy with its zonal, meridional kinetic and available potential energy terms having equal contributions, or the weighted ocean heat content in which a disturbance is applied only to the initial temperature fields. The choices of a reference state for defining the initial anomalies are such that either perturbations on seasonal timescales and or on interannual timescales are constructed. These project a-priori only the slow modes of the ocean physical processes, such that the disturbances grow mainly in the Western Boundary Currents, in the Antarctic Circumpolar Current and the El Nino Southern Oscillation regions. An additional set of initial conditions is designed to fit in a least square sense data from global ocean reanalysis. Applying the AT produced sets of disturbances to oceanic initial conditions initialized by observations of the MPIOM-ESM coupled model on T63L47/GR15 resolution, four ensemble and one hind-cast experiments were performed. The weighted total energy norm is used to monitor the amplitudes and rates of the fastest growing error modes. The results showed minor dependence of the instabilities or error growth on the selected metric but considerable change due to the magnitude of the scaling amplitudes of the perturbation patterns. In contrast to similar atmospheric applications, we find an energy conversion from kinetic to available potential energy, which suggests a different source of uncertainty generation in the ocean than in the atmosphere mainly associated with changes in the density field.

But the eager contest and the powerful desire for more profits beside the human interest for welfare and development closed all minds about the expected severe destuctive impacts on our earth planet. Also, we have to remember that the majority of the African, Asian and Latin American countries are still in the first stage of their development and if they will be left to generate all their demand of energy by the conventional machine e.g (Fossil Fuel, Biofuel and Nuclear Fuel), then our Earth planet will confront an endless and ceasless severe destructive impacts due to the encroach of the released hot Carbon Doxide and hot vapours of Acids which will never forgive any fruitful aspect in our Earth Planet from destruction. 1. Importance of the New Project. Building the Extra cheap, clean Power plants with safe and smooth Operation in addition to the long life time in service for generating enough and plentiful electric energy the sustainable renwable resources will invigorate the foresaking of all Nuclear, Fossil and Biofuel power plants to avoide the nuclear hazards and stop releasing the hot carbon doxide, hot acids for the recovery of our ill environment. Also, the main sustainable, renewable, and cheap resources for generating the bulky capacity of the electric energy in our project are the Sun and the Oceans in addition to all Seas Surrounding all Continents in our Earth planet. Therefore, our recourses are so much enormous plentiful, clean, and renewable. 2. .Generation of Electricity from Solar Energy by Photovoltiac Cells (PVCs) or Concentrated Solar Power (CSP).

    The air-sea exchange of heat, gas and momentum plays an important role for the Earth's weather and global climate. The exchange processes between ocean and atmosphere are influenced by the prevailing surface ocean dynamics. This surface ocean is a highly turbulent region where there is enhanced production of turbulent kinetic energy (TKE). The dissipation rate of TKE (ɛ) in the surface ocean is an important process for governing the depth of both the mixing and mixed layers, which are important length-scales for many aspects of ocean research. However, there exist very limited observations of ɛ under open ocean conditions and consequently our understanding of how to model the dissipation profile is very limited. The approaches to model profiles of ɛ that exist, differ by orders of magnitude depending on their underlying theoretical assumption and included physical processes. Therefore, scaling ɛ is not straight forward and requires open ocean measurements of ɛ to validate the respective scaling laws. This validated scaling of ɛ, is for example required to produce accurate mixed layer depths in global climate models. Errors in the depth of the ocean surface boundary layer can lead to biases in sea surface temperature. Here, we present open ocean measurements of ɛ from the Air-Sea Interaction Profiler (ASIP) collected during several cruises in different ocean basins. ASIP is an autonomous upwardly rising microstructure profiler allowing undisturbed profiling up to the ocean surface. These direct measurements of ɛ under various types of atmospheric and oceanic conditions along with measurements of atmospheric fluxes and wave conditions allow us to make a unique assessment of several scaling approaches based on wind, wave and buoyancy forcing. This will allow us to best assess the most appropriate ɛ-based parameterisation for air-sea exchange.

    Cleanrooms, critical to a wide range of industries, universities, and government facilities, are extremely energy intensive. Consequently, energy represents a significant operating cost for these facilities. Improving energy efficiency in cleanrooms will yield dramatic productivity improvement. But more importantly to the industries which rely on cleanrooms, base load reduction will also improve reliability. The number of cleanrooms in the US is growing and the cleanroom environmental systems' energy use is increasing due to increases in total square footage and trends toward more energy intensive, higher cleanliness applications. In California, many industries important to the State's economy utilize cleanrooms. In California these industries utilize over 150 cleanrooms with a total of 4.2 million sq. ft. (McIlvaine). Energy intensive high tech buildings offer an attractive incentive for large base load energy reduction. Opportunities for energy efficiency improvement exist in virtually all operating cleanrooms as well as in new designs. To understand the opportunities and their potential impact, Pacific Gas and Electric Company sponsored a project to benchmark energy use in cleanrooms in the electronics (high-tech) and biotechnology industries. Both of these industries are heavily dependent intensive cleanroom environments for research and manufacturing. In California these two industries account for approximately 3.6 million sq. ft. of cleanroom (McIlvaine, 1996) and 4349 GWh/yr. (Sartor et al. 1999). Little comparative energy information on cleanroom environmental systems was previously available. Benchmarking energy use allows direct comparisons leading to identification of best practices, efficiency innovations, and highlighting previously masked design or operational problems

    This paper describes the research, design, construction and prototype testing process of a novel ocean energy direct drive permanent magnet linear generator buoy. The buoy employs the vertical component of the motion of ocean waves to power a linear generator. The generator consists of a permanent magnet field system (mounted on the central translator shaft) and an armature, in which the power is generated (mounted on the buoy). The translator shaft is anchored to the sea floor, and the buoy/floater moves armature coils relative to the permanent magnet translator to induce voltages. The electrical and mechanical structures of the buoy generator are provided, along with performance characteristics, including voltage, current and developed power. (author)

    Integrating energy production and energy consumption to produce a total energy system within an energy industrial center which would result in more power production from a given energy source and less pollution of the environment is discussed. Strong governmental support would be required for the crash drilling program necessary to implement these concepts. Cooperation among the federal agencies, power producers, and private industry would be essential in avoiding redundant and fruitless projects, and in exploiting most efficiently our geothermal resources.

    Growing concern in Taiwan has arisen about energy consumption and its adverse environmental impact. The current situation of energy conservation in high energy-consuming industries in Taiwan, including the iron and steel, chemical, cement, pulp and paper, textiles and electric/electrical industries has been presented. Since the energy consumption of the top 100 energy users (T100) comprised over 50% of total industry energy consumption, focusing energy consumption reduction efforts on T100 energy users can achieve significant results. This study conducted on-site energy audits of 314 firms in Taiwan during 2000-2004, and identified potential electricity savings of 1,022,656 MWH, fuel oil savings of 174,643 kiloliters (KL), steam coal savings of 98,620 ton, and natural gas (NG) savings of 10,430 kilo cubic meters. The total potential energy saving thus was 489,505 KL of crude oil equivalent (KLOE), representing a reduction of 1,447,841 ton in the carbon dioxide emissions, equivalent to the annual carbon dioxide absorption capacity of a 39,131-ha plantation forest

    Energy is required to maintain physiological homeostasis in response to environmental change. Although responses to environmental stressors frequently are assumed to involve high metabolic costs, the biochemical bases of actual energy demands are rarely quantified. We studied the impact of a near-future scenario of ocean acidification [800 µatm partial pressure of CO2 (pCO2)] during the development and growth of an important model organism in developmental and environmental biology, the sea urchin Strongylocentrotus purpuratus. Size, metabolic rate, biochemical content, and gene expression were not different in larvae growing under control and seawater acidification treatments. Measurements limited to those levels of biological analysis did not reveal the biochemical mechanisms of response to ocean acidification that occurred at the cellular level. In vivo rates of protein synthesis and ion transport increased ∼50% under acidification. Importantly, the in vivo physiological increases in ion transport were not predicted from total enzyme activity or gene expression. Under acidification, the increased rates of protein synthesis and ion transport that were sustained in growing larvae collectively accounted for the majority of available ATP (84%). In contrast, embryos and prefeeding and unfed larvae in control treatments allocated on average only 40% of ATP to these same two processes. Understanding the biochemical strategies for accommodating increases in metabolic energy demand and their biological limitations can serve as a quantitative basis for assessing sublethal effects of global change. Variation in the ability to allocate ATP differentially among essential functions may be a key basis of resilience to ocean acidification and other compounding environmental stressors.

  15. On the dynamics of a novel ocean wave energy converter

    KAUST Repository

    Orazov, B.

    2010-11-01

    Buoy-type ocean wave energy converters are designed to exhibit resonant responses when subject to excitation by ocean waves. A novel excitation scheme is proposed which has the potential to improve the energy harvesting capabilities of these converters. The scheme uses the incident waves to modulate the mass of the device in a manner which amplifies its resonant response. To illustrate the novel excitation scheme, a simple one-degree of freedom model is developed for the wave energy converter. This model has the form of a switched linear system. After the stability regime of this system has been established, the model is then used to show that the excitation scheme improves the power harvesting capabilities by 2565 percent even when amplitude restrictions are present. It is also demonstrated that the sensitivity of the device\\'s power harvesting capabilities to changes in damping becomes much smaller when the novel excitation scheme is used. © 2010 Elsevier Ltd.

  16. Energy conservation in the primary aluminum and chlor-alkali industries

    Energy Technology Data Exchange (ETDEWEB)

    1980-10-01

    The primary aluminum and chlor-alkali industries together use nearly 13% of the electrical energy consumed by US industry. As part of its mission to promote energy conservation in basic US industries, the DOE surveys the present technological status of the major electrochemical industries and evaluates promising technological innovations that may lead to reduced energy requirements. This study provides technical and economic analyses in support of a government program of research and development in advanced electrolytic technology. This program is intended to supplement the development efforts directed toward energy savings by private industry. Sections II and III of this report cover aluminum and chlorine production processes only, since these two industries represent over 90% of the electrical energy requirements of all electrolytic industries in the United States. Section IV examines barriers to accelerated research and development by the electrolytic industries, and makes suggestions for government actions to overcome these barriers.

    Research on conditions to develop new innovations within emerging renewable energy industries is often done with a national focus. However, recent research on international entrepreneurship has revealed that firms operate on international levels very early in their life time. Thus, based on former research on international entrepreneurship and case examples, we build the propositions that firms in the marine energy industry use internationalization as a strategy to overcome industry barriers. Our primary source of data is a unique dataset from a global survey of all the companies in the marine energy industry who are aiming to commercialize a wave or tidal energy device. This paper is organized in two steps: first we identified the most challenging industry barriers perceived by companies. Second we use these to form propositions which we assess through empirical data. The two most challenging barriers perceived by the companies are need for capital and need for supportive political schemes. Our findings reveal that internationalization certainly is a common strategy to access capital and attractive support schemes in foreign countries. The early internationalization has implications for researchers, managers and policy makers. - Research highlights: → Industry barriers identified as access to capital and supportive political schemes. → International entrepreneurship is used to overcome industry barriers. → Start-ups in emerging energy industries 'shop' national support schemes. → Future research to provide policy advice should adapt to the international reality. → Research based on a worldwide survey of wave and tidal energy device developers.

    In volume 8/1986 of this periodical, Brazil's moving away from the program for the building and expansion of a national nuclear power industry had been reported on back of foreign currencies and urgently necessary saving measures of the public means influence not only the construction of nuclear power plants, they also decay instruments in other areas of energy industry. In the area of electric power, some nationalisations have already taken place and in petroleum supply, the need for imports is increasing again. Furthermore, there is reason to believe that some of the energy-political solutions which Brazil had chosen as answers to the petroleum price shocks of 1973/74 and 1979/80 are likely to lead to some considerable problems in the near future. In the middle of these crises in which Brazil's energy industry has been for some time now, there is nonetheless one spectacular event. Brazil's President, Mr. Jose Sarney, announced the command of the nuclear cycle by means of national technology. (orig.) [de

    With economic development and the change of industrial structure, industrial relocation is an inevitable trend. In the process of industrial relocation, environmental externality and social cost could occur due to market failure and government failure. Little attention has been paid to this issue. In this paper, we address it with a theoretical analysis and an empirical investigation on the relationship between China's industrial relocation in the early 1990s and energy consumption which is the primary source of CO 2 emission, an environmental externality that causes increasing concerns. The macro-policy analysis suggests that there would be a positive link between China's industrial relocation in the early 1990s and energy saving (and environmental externalities reduction). Using fixed-effect regression model and simulation method, we provide an empirical support to this argument. In order to further reduce environmental externalities and social cost in the process of industrial relocation, we provide policy suggestions as follows: First, strengthen the evaluation of environmental benefits/costs; Second, pay more attention to the coordinated social-economic development; Third, avoid long-lived investment in high-carbon infrastructure in areas with industries moved in; Fourth, address employment issue in the areas with industries moved out. - Research highlights: → Little attention has been paid to the linkage between industrial relocation and environmental externality. → Our macro-policy analysis suggests that there would be a positive link between China's industrial relocation in the early 1990s and energy saving (and environmental externalities reduction). → Using fixed-effect regression model and simulation method, we find a positive link between China's industrial relocation in the early 1990s and energy saving. → Policy suggestions to further reduce environmental externalities and social cost in the process of industrial relocation are discussed.

    Industry utilizes very complex systems, consisting of equipment and their human interface, which are organized to meet the production needs of the business. Effective and sustainable energy efficiency programs in an industrial setting require a systems approach to optimize the integrated whole while meeting primary business requirements. Companies that treat energy as a manageable resource and integrate their energy program into their management practices have an organizational context to continually seek opportunities for optimizing their energy use. The purpose of an energy management system standard is to provide guidance for industrial and commercial facilities to integrate energy efficiency into their management practices, including fine-tuning production processes and improving the energy efficiency of industrial systems. The International Organization for Standardization (ISO) has identified energy management as one of its top five priorities for standards development. The new ISO 50001 will establish an international framework for industrial, commercial, or institutional facilities, or entire companies, to manage their energy, including procurement and use. This standard is expected to achieve major, long-term increases in energy efficiency (20percent or more) in industrial, commercial, and institutional facilities and to reduce greenhouse gas (GHG) emissions worldwide.This paper describes the impetus for the international standard, its purpose, scope and significance, and development progress to date. A comparative overview of existing energy management standards is provided, as well as a discussion of capacity-building needs for skilled individuals to assist organizations in adopting the standard. Finally, opportunities and challenges are presented for implementing ISO 50001 in emerging economies and developing countries.

    This paper analyzes China's policy approach to renewable energies and assesses how effectively China has met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy. First we briefly discuss the interactions between these two policies. Then we outline China's key renewable energy and renewable industrial policies and find that China's government has well recognized the need for this policy interaction. After that, we study the achievements and problems in China's wind and solar PV sector during 2005–2012 and argue that China's policy approach to renewable energies has placed priority first on developing a renewable energy manufacturing industry and only second on renewable energy itself, and it has not effectively met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy. Lastly, we make an in-depth analysis of the three ideas underlying this policy approach, that is, the green development idea, the low-carbon leadership idea and indigenous innovation idea. We conclude that Chinas' policy approach to renewable energies needs to enhance the interactions between renewable energy policy and renewable energy industrial policy. The paper contributes to a deeper understanding of China's policy strategy toward renewable energies. -- Highlights: •Interactions between renewable energy policy and renewable energy industrial policy are discussed. •China's key renewable energy and renewable energy industrial policies are outlined. •Two empirical cases illustrate China's policy approach to renewable energies. •We argue that China needs to enhance the interactions between the two policies. •Three ideas underlie China's policy approach to renewable energies

    Usenius, A.

    1982-12-01

    The energy research project of the mechanical forest industry studied the energy consumption in 1979 and the possibilities to save energy in the sawmill, plywood, particleboard, fibreboard, joinery, wooden houses, gluelam and impregnation industries. The energy consumption per product unit is on the minimum level in sawmilling, 1.38 GJ/m/sup 3/, and on the maximum level in fibreboard manufacturing, 9.98 GJ/t. In plywood production, 6.95 GJ/m/sup 3/, the energy consumption is about double compared with the consumption in particleboard production, 3.40 GJ/m/sup 3/. The main part of the energy is heat. In the drying process about 70-85% of the total energy is used in individual processes. Over a half, 53.9%, of the total energy consumption, 23 169 TJ, is used in sawmill industry. The proportion of plywood industry is 19.2%, of particleboard industry 12.2% and of fibreboard industry 7.2%. The proportion of the processing industry is 7.5%; the main part is used in joinery industry. The fuel consumption in transportation of wooden raw materials was 2 260 TJ and in transportation of products 4 800 TJ. In fibreboard industry it is possible to save energy by leading the waste steam from defibratory into chip silos for preheating of the chips. In veneer and chip drying it is possible to save energy by using higher moisture content of the drying air and by utilizing the drying capacity as well as possible. In kiln drying of timber the changing of drying circumstances can in some cases save 50-150 FIM per 1 cbm of dried timber.

  16. EU energy-intensive industries and emissions trading: losers becoming winners?

    Energy Technology Data Exchange (ETDEWEB)

    Wettestad, Joergen

    2008-11-15

    The EU Emissions Trading System (ETS) initially treated power producers and energy-intensive industries similarly, despite clear structural differences between these industries regarding pass through of costs and vulnerability to global competition. Hence, the energy-intensive industries could be seen as losing out in the internal distribution. In the January 2008 proposal for a reformed ETS post-2012, a differentiated system was proposed where the energy-intensive industries come out relatively much better. What is the explanation for the change taking place? Although power producers still have a dominant position in the system, the increasing consensus about windfall profits has weakened their standing. Conversely, the energy-intensive industries have become better organised and more active. This balance shift is first and foremost noticeable in several important EU-level stake holder consultation processes. Energy-intensive industries have, however, also successfully utilised the national pathway to exert influence on Brussels policy-making. Finally, growing fear of lax global climate policies and related carbon leakage has strengthened the case of these industries further. The latter dimension indicates that although energy-intensive industries have managed to reduce internal distribution anomalies, external challenges remain. (author). 9 refs

    The industrial sector is the second largest consumer of energy in Malaysia. In this energy audit, the most important parameters that have been collected are as follows: power rating and operation time of energy-consuming equipments/machineries; fossil fuel and other sources of energy use; production figure; peak and off-peak tariff usage behavior and power factor. These data were then analyzed to investigate the breakdown of end-use equipments/machineries energy use, the peak and off-peak usage behavior, power factor trend and specific energy use. The results of the energy audit showed that the highest electrical energy-using equipment was an electric motor followed by pumps and air compressors. The specific energy use has been estimated and compared with four Indonesian industries and it was found that three Malaysian industries were more efficient than the Indonesian counterpart. The study also found that about 64% electrical energy was used in peak hours by the industries and the average power factor ranged from 0.88 to 0.92. The study also estimated energy and bill savings using highly efficient electrical motors along with the payback period. (author)

    Shi, G.-M.; Bi Jun; Wang Jinnan

    2010-01-01

    Data envelopment analysis (DEA) has recently become a popular method in measuring energy efficiency at the macro-economy level. However, previous studies are limited in that they failed to consider the issues of undesirable outputs and minimisation of energy consumption. Thus, this study considers both factors in measuring Chinese industrial energy efficiency and investigates the maximum energy-saving potential in 28 administrative regions in China. The results show that industries in the east area have the best average energy efficiency for the period 2000-2006, followed by the central area. Further, after comparing the industrial energy overall efficiency, pure technical efficiency (IEPTE), and scale efficiency of the 28 administrative regions examined, the study finds that in most regions of this study, the two main reasons causing the wastage of a large amount of energy during the industrial production process are that the industrial structure of most regions still relies on the massive use of energy in order to support the industrial-based economy and the IEPTE is too low. Based on these findings, this paper correspondingly proposes some policies to improve regional industrial energy efficiency.

    Effects extended to industrial areas by new energy development were analyzed by using the industrial relation table. Technological development of new energies can mass-produce energy without being restricted by energy resource availability, and retaining manufacturing facilities can exhibit energy reserve function with security. The technologies may be suitable for local energy supply. In the aspects of industrial policies and people's living, demands on diversification and improvement of the people's living may be responded, levels of scientific technologies may be enhanced, and contribution to improving the industrial structure may be expected. The energy industry includes a large number of related industries and has vast related areas. A large number of technology induced effects can be expected in the course of research and development. A market of huge size may be estimated in the future, by which level elevation of the industrial structure would be supported. Early promotion of the new energy development is an urgent assignment for the 1980's. In order to achieve this goal, it is necessary to promote research and development, proliferation and practical application, for which the physical strength of the present Japan must be utilized to its maximum in making human and fund investments. Expansion and improvement in the industrialization infrastructures are also important, whereas the government's subsidies must be increased, and vitality in the private sector must be incorporated into organized force.

    The Ocean Thermal Extractable Energy Visualization (OTEEV) project focuses on assessing the Maximum Practicably Extractable Energy (MPEE) from the world's ocean thermal resources. MPEE is defined as being sustainable and technically feasible, given today's state-of-the-art ocean energy technology. Under this project the OTEEV team developed a comprehensive Geospatial Information System (GIS) dataset and software tool, and used the tool to provide a meaningful assessment of MPEE from the global and domestic U.S. ocean thermal resources. The OTEEV project leverages existing NREL renewable energy GIS technologies and integrates extractable energy estimated from quality-controlled data and projected optimal achievable energy conversion rates. Input data are synthesized from a broad range of existing in-situ measurements and ground-truthed numerical models with temporal and spatial resolutions sufficient to reflect the local resource. Energy production rates are calculated for regions based on conversion rates estimated for current technology, local energy density of the resource, and sustainable resource extraction. Plant spacing and maximum production rates are then estimated based on a default plant size and transmission mechanisms. The resulting data are organized, displayed, and accessed using a multi-layered GIS mapping tool, http://maps.nrel.gov/mhk_atlas with a user-friendly graphical user interface.

    Full Text Available The Smart Grid vision imposes a new approach towards energy supply that is more affordable, reliable and sustainable. The core of this new vision is the use of advanced technology to monitor power system dynamics in real time and identify system in stability. In order to implement strategic vision for energy management, it is possible to identify three main areas of investigation such as smart generation, smart grid and smart customer. Focusing on the latter topic, in this paper we present an application specifically designed to monitor an industrial site with particular attention to power consumption. This solution is a real time analysis tool, able to produce useful results to have a strategic approach in the energy market and to provide statistic analysis useful for the future choices of the industrial company. The application is based on a three layers architecture. The technological layer uses a Wireless Sensor Network (WSN to acquire data from the electrical substations. The middleware layer faces the integration problems by processing the raw data. The application layer manages the data acquired from the sensors. This WSN based architecture represents an interesting example of a low cost and non-invasive monitoring application to keep the energy consumption of an industrial site under control. Some of the added value features of the proposed solution are the routing network protocol, selected in order to have an high availability of the WSN, and the use of the WhereX middleware, able to easily implement integration among the different architectural parts.

    With the rapid economic development, energy consumption of China has been the second place in the world next to the USA. Usually, measuring energy consumption intensity or efficiency applies heat unit which is joule per gross domestic production (GDP) or coal equivalent per GDP. However, this measuring approach is only oriented by the conversion coefficient of heat combustion which does not match the real value of the materials during their formation in the ecological system. This study applied emergy analysis to evaluate the energy consumption intensity to fill this gap. Emergy analysis is considered as a bridge between ecological system and economic system, which can evaluate the contribution of ecological products and services as well as the load placed on environmental systems. In this study, emergy indicator for performing energy consumption intensity of primary energy was proposed. Industrial production is assumed as the main contributor of energy consumption compared to primary and tertiary industries. Therefore, this study validated this method by investigating the two industrial case studies which were Dalian Economic Development Area (DEDA) and Fuzhou economic and technological area (FETA), to comparatively study on their energy consumption intensity between the different kinds of industrial systems and investigate the reasons behind the differences. The results show that primary energy consumption (PEC) of DEDA was much higher than that of FETA during 2006 to 2010 and its primary energy consumption ratio (PECR) to total emergy involvement had a dramatically decline from year 2006 to 2010. In the same time, nonrenewable energy of PEC in DEDA was also much higher than that in FETA. The reason was that industrial structure of DEDA was mainly formed by heavy industries like petro-chemistry industry, manufacturing industries, and high energy-intensive industries. However, FETA was formed by electronic business, food industry, and light industries. Although

    Geothermal energy is widely used in Iceland for space heating swimming pools and snow melting systems as well as for greenhouses and soil heating and aquaculture. Its contribution to the standard of living in Iceland is very substantial. The industrial applications are, however, fewer today than anticipated twenty years ago. This paper considers some of the socio-economic reasons for that. Although geothermal energy is generally a cost competitive source of energy, it is site limited and does not by itself provide sufficient economic incentive to attract manufacturing or process industries. This generally requires another, locally available production factor offering further competitive advantage to justify greenfield investments. World economic slow-downs, and structural problems in many process industries after the energy crisis of the seventies have reduced interest for investments in energy intensify industries world wide. While public sector initiative motivated by technological possibilities was instrumental for developing geothermal resources in the past, time has now come for private sector initiative, led by market interest, to identify and exploit opportunities for using geothermal energy for industrial purposes. National and local governments must, however, provide the appropriate incentives to stimulate such developments

    This report for the Swiss Federal Office of Energy (SFOE) presents the results of a study made on drying processes used in industry and possible ways of promoting investment in measures to increase the efficient use of energy. The energy consumption of dehydration and drying processes used in industry is examined and the savings potential for these processes estimated. Examples of the processes investigated are given and figures for the energy consumption for dehydration and drying processes in several different industrial sectors are quoted. The report then examines, on the one hand, the factors that hem innovations in this area and, on the other, those that promote them. Further, the report looks into which reasons are responsible for the realisation or non-realisation of technically and economically viable solutions for improving the energy-efficiency of the dehydration and drying processes.

    Effects extended to industrial areas by new energy development were analyzed by using the industrial relation table. Technological development of new energies can mass-produce energy without being restricted by energy resource availability, and retaining manufacturing facilities can exhibit energy reserve function with security. The technologies may be suitable for local energy supply. In the aspects of industrial policies and people's living, demands on diversification and improvement of the people's living may be responded, levels of scientific technologies may be enhanced, and contribution to improving the industrial structure may be expected. The energy industry includes a large number of related industries and has vast related areas. A large number of technology induced effects can be expected in the course of research and development. A market of huge size may be estimated in the future, by which level elevation of the industrial structure would be supported. Early promotion of the new energy development is an urgent assignment for the 1980's. In order to achieve this goal, it is necessary to promote research and development, proliferation and practical application, for which the physical strength of the present Japan must be utilized to its maximum in making human and fund investments. Expansion and improvement in the industrialization infrastructures are also important, whereas the government's subsidies must be increased, and vitality in the private sector must be incorporated into organized force.

    This chapter presents an overview of current hydro, ocean, wave and tidal initiatives. Large hydro remains one of the lowest-cost generating technologies, although environmental constraints, resettlement impacts and the limited availability of sites have restricted further growth in many countries. Large hydro supplied 16 % of global electricity in 2004, down from 19 % a decade ago. Large hydro capacity totalled about 720 GW worldwide in 2004 and has grown historically at slightly more than 2 % annually. China installed nearly 8 GW of large hydro in 2004, taking the country to number one in terms of installed capacity (74 GW). With the completion of the Three Gorges Dam, China will add some 18.2 GW of hydro capacity in 2009. The socio-economic benefits of hydro include improved flood control and water supply. The socio-economic benefits of hydro include improved flood control and water supply. The socio-economic cost of hydro includes displacements and submergence. Further hydro can improve peak-capacity management. Ocean currents, some of which runs close to European coasts, carry a lot of kinetic energy. Part of this energy can be captured by sub-marine windmills and converted into electricity. These are more compact than the wind turbines used on land, simply because water is much denser than air. The main European countries with useful current power potential are France and the UK. Ocean tides are driven by the gravitational pull of the moon. With one high tide every 12 hours, a tidal power plant can operate for only four or five hours per cycle, so power from a single plant is intermittent. A suitably-designed tidal plant can, however, operate as a pimped storage system, using electricity during periods of low demand to store energy that can be recovered later. The only large, modern example of a tidal power plant is the 240 MW La Rance plant, built in France in the 1960s, which represents 91 % of the world tidal power capacity. Wave energy can be seen as

    Mining in British Columbia is the second largest industrial electricity consumer. This presentation highlighted methods to help the mining industry reduce their energy requirements by limiting waste and improving efficiency. The measures are aimed at optimizing energy-use and efficiency in mining and processing and identifying opportunities and methods of improving this efficiency. Energy conservation in comminution and beneficiation is a primary focus of research activities at the University of British Columbia (UBC). The objective is to reduce energy usage in metal mines by 20 per cent overall. Open pit copper, gold and molybdenum mines are being targeted. Projects underway at UBC were outlined, with particular reference to energy usage, recovery and alternative energy sources; preconcentration; reducing energy usage from comminution in sorting, high pressure grinding rolls and high speed stirred mills; Hydromet; other energy efficient technologies such as control and flotation; and carbon dioxide sequestration. Studies were conducted at various mining facilities, including mines in Sudbury, Ontario. tabs., figs.

    Europe''s energy-intensive industries have banded together to attack the European Commission''s latest proposal for a carbon-energy tax. Instead of passing a new directive--which the commission has been trying to do for five years--it now wants to expand existing duties on mineral oils to cover coal, natural gas, and electricity. The commission also aims to increase the mineral oil duties. Energy-intensive industries--including producers of chemicals, cars, cement, lime, iron, steel, and other metals--say the plans would destroy their competitiveness. They say they are improving energy efficiency voluntarily and urge the commission to focus on liberalizing Europe''s gas and electricity markets, which would reduce prices

    The U.S. glass industry is comprised of four primary industry segments--flat glass, container glass, specialty glass, and fiberglass--which together consume $1.6 billion in energy annually. On average, energy costs in the U.S. glass industry account for around 14 percent of total glass production costs. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There is a variety of opportunities available at individual plants in the U.S. glass industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, system, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the U.S. glass industry is provided along with a description of the major process steps in glass manufacturing. Expected savings in energy and energy-related costs are given for many energy efficiency measures, based on case study data from real-world applications in glass production facilities and related industries worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers in the U.S. glass industry reduce energy consumption in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of the measures--as well on as their applicability to different production practices--is needed to assess potential implementation of selected technologies at individual plants.

    Highlights: • A methodology to estimate ORC industrial heat recovery potential is defined. • Heat recovery applications for different industrial processes are shown. • Cement, steel, glass and oil and gas applications are considered in EU27. • Savings in electricity costs and greenhouse gases are quantified. - Abstract: Organic Rankine Cycle (ORC) is a technology with important opportunities in heat recovery from energy intensive industrial processes. This paper represents the first comprehensive estimate of ORC units that can be installed in cement, steel, glass and oil and gas industries in the 27 countries of the European Union based on an accurate methodology related to real plants in operation or under construction. An evaluation of energy savings, depending on the number of operating hours per year and of the consequent decrease in CO 2 emission and electricity expenditure, is also provided. The study, carried out in the framework of an European research project on heat recovery in energy intensive industries, found that, in the most convenient considered scenario, up to about 20,000 GW h of thermal energy per year can be recovered and 7.6 M ton of CO 2 can be saved by the application of ORC technology to the investigated and most promising industrial sectors

  7. Sustainable desalination using ocean thermocline energy

    The conventional desalination processes are not only energy intensive but also environment un-friendly. They are operating far from thermodynamic limit, 10–12%, making them un-sustainable for future water supplies. An innovative desalination processes are required to meet future sustainable desalination goal and COP21 goal. In this paper, we proposed a multi-effect desalination system operated with ocean thermocline energy, thermal energy harnessed from seawater temperature gradient. It can exploit low temperature differential between surface hot water temperature and deep-sea cold-water temperature to produce fresh water. Detailed theoretical model was developed and simulation was conducted in FORTRAN using international mathematical and statistical library (IMSL). We presented four different cases with deep-sea cold water temperature varies from 5 to 13°C and MED stages varies from 3 to 6. It shows that the proposed cycle can achieve highest level of universal performance ratio, UPR = 158, achieving about 18.8% of the ideal limit. With the major energy input emanated from the renewable solar, the proposed cycle is truly a “green desalination” method of low global warming potential (GWP), best suited for tropical coastal shores having bathymetry depths up to 300m or more.

  8. New approaches for improving energy efficiency in the Brazilian industry

    Full Text Available The Brazilian government has been promoting energy efficiency measures for industry since the eighties but with very limited returns, as shown in this paper. The governments of some other countries dedicated much more effort and funds for this area and reached excellent results. The institutional arrangements and types of programmes adopted in these countries are briefly evaluated in the paper and provide valuable insights for several proposals put forward here to make more effective the Brazilian government actions directed to overcome market barriers and improve energy efficiency in the local industry. The proposed measures include the creation of Industrial Assessment Centres and an executive agency charged with the coordination of all energy efficiency programmes run by the Federal government. A large share of the Brazilian industry energy consumption comes from energy-intensive industrial branches. According to a recent survey, most of them have substantial energy conservation potentials. To materialize a fair amount of them, voluntary targets concerning energy efficiency gains should start to be negotiated between the Government and associations representing these industrial branches. Credit facilities and tax exemptions for energy-efficient equipment’s should be provided to stimulate the interest of the entrepreneurs and the setting-up of bolder targets.

  10. Geophysical Potential for Wind Energy over the Open Oceans

    2017-12-01

    Wind turbines continuously remove kinetic energy from the lower troposphere thereby reducing the wind speed near hub height. The rate of electricity generation in large wind farms containing multiple wind arrays is therefore constrained by the rate of kinetic energy replenishment from the atmosphere above. In particular, this study focuses on the maximum sustained transport of kinetic energy through the troposphere to the lowest hundreds of meters above the surface. In recent years, a growing body of research argues that the rate of generated power is limited to around 1.5 Wm-2 within large wind farms. However, in this study we demonstrate that considerably higher power generation rates may be sustainable over some open ocean areas in giant wind farms. We find that in the North Atlantic maximum extraction rates of up to 6.7 Wm-2 may be sustained by the atmosphere in the annual mean over giant wind farm areas approaching the size of Greenland. In contrast, only a third of this rate is sustained on land for areas of equivalent size. Our simulations indicate a fundamental difference in response of the troposphere and its vertical kinetic energy flux to giant near-surface wind farms. We find that the surface heat flux from the oceans to the atmosphere may play an important role in creating regions where large sustained rates of downward transport of kinetic energy and thus rates of kinetic energy extraction may be geophysically possible. While no commercial-scale deep-water wind turbines yet exist, our results suggest that such technologies, if they became technically and economically feasible, could potentially provide civilization-scale power.

    Greening of industry is a prominent topic on the European agenda and has received a new impetus with the Kyoto process, where the European Union and its member states are facing new obligations. Due to its role as a major infrastructure sector and due to its extensive emissions, the electricity sector has become a focal industry in this context. These same factors, as well as the large public ownership has, in fact, traditionally placed energy in a central public political focus. The energy and electricity sector hence exemplify the intertwined nature of economics and politics in sector developments, where technology choices and capacity expansions have numerous motivations and diverse interests to please. This report discusses ''green'' innovation in the energy industry. By selecting some of the most advanced examples of breakthrough for new green technologies in Europe, it explores the basic elements of successful greening of industry. To account for the fact that product innovation- and diffusion-processes are embedded in a complex politico-economic setting, we have developed an analytical framework, incorporating both economic, political and societal elements and the interplay between them. More specifically, environmentally oriented innovation is seen as evolving out of the interplay between: 1) a technical-commercial core (major market agents, i.e. the renewable energy supply industry, associated complementary industries and consumers); 2) the political-administrative system; and 3) the societal basis, referring to existing societal customs, norms, and modes of social organisation. Drawing on Porter's (1990) analysis of business clusters, we have termed our focus ''green energy-industrial cluster'' emergence and growth. We have taken Porter's attempt to break out of a limited market analysis into a broader strategic focus one step further, where the political and institutional dimensions are more explicitly included. This implies that we see the emergence of

    2011-01-01

    The study evaluates the energy saving potential of the Chinese steel industry by studying its potential future energy efficiency gap. In order to predict the future energy efficiency gap, a multivariate regression model combined with risk analysis is developed to estimate future energy intensity of China's steel industry. It is found that R and D intensity, energy saving investment, labor productivity and industry concentration are all important variables that affect energy intensity. We assess the possible measures as to how China's steel industry can narrow the energy efficiency gap with Japan by means of scenario analysis. Using Japan's current energy efficiency level as baseline, the energy saving potential of China's steel industry is more than 200 million ton coal equivalent in 2008, and it would fall to zero in 2020. However, if greater efforts were made to conserve energy, it would be possible to narrow down the energy efficiency gap between China and Japan by around 2015. Finally, using the results of the scenario analysis, future policy priorities for energy conservation in China's steel industry are assessed in this paper. - Highlights: → The energy saving potential of the Chinese steel industry is evaluated. → A multivariate regression model combined with risk analysis is developed. → R and D, energy saving investment, labor, and structure affect energy intensity.→ The energy saving potential of China's steel industry would fall to zero in 2020.→ Future policy for energy conservation in China's steel industry are assessed.

    This paper tries to assess the relationship between disaggregate energy consumption and industrial output in South Africa by undertaking a cointegration analysis using annual data from 1980 to 2005. We also investigate the causal relationships between the various disaggregate forms of energy consumption and industrial production. Our results imply that industrial production and employment are long-run forcing variables for electricity consumption. Applying the [Toda, H.Y., Yamamoto, T., 1995. Statistical inference in vector autoregressions with possibly integrated processes. Journal of Econometrics 66, 225-250] technique to Granger-causality, we find bi-directional causality between oil consumption and industrial production. For the other forms of energy consumption, there is evidence in support of the energy neutrality hypothesis. There is also evidence of causality between employment and electricity consumption as well as coal consumption causing employment.

    In the worldwide practice, the geothermal energy application, as an alternative energy resource, can be of great importance. This is especially case in the countries where exceptional natural geothermal potential exists. Despite using geothermal energy for both greenhouses heating and balneology, the one can be successfully implemented in the heat requiring industrial processes. This kind of use always provides greater annual heat loading factor, since the industrial processes are not seasonal (or not the greater part of them). The quality of the geothermal resources that are available in Europe, dictates the use within the low-temperature range technological processes. However, these processes are significantly engaged in different groups of processing industries. But, beside this fact the industrial application of geothermal energy is at the beginning in the Europe. (Original)

    The small- and meso-scale ocean response to wind parks has not been investigated in the southern North Sea until now with the help of high-resolution numerical modelling. Obstacles such as e.g. wind turbine piles may influence the ocean current system and produce turbulent kinetic energy which could affect sediment dynamics in the surrounding area. Two setups of the unstructured-grid model SCHISM (Semi-implicit Cross-scale Hydroscience Integrated System Model) have been developed for an idealized channel including a surface piercing cylindrical obstacle representing the pile and a more realistic test case including four exemplary piles. Experiments using a constant flow around the obstacles and a rotating M2 tidal wave are carried out. The resulting current and turbulence patterns are investigated to estimate the influence of the obstacles on the surrounding ocean dynamics. We demonstrate that using an unstructured ocean model provides the opportunity to embed a high-resolution representation of a wind park turbine pile system into a coarser North Sea setup, which is needed in order to perform a seamless investigation of the resulting geophysical processes.

    The U.S. Department of Energy (US DOE) has mobilized its National Laboratories to address the broad range of environmental effects of ocean and river energy development. The National Laboratories are using a risk-based approach to set priorities among environmental effects, and to direct research activities. Case studies will be constructed to determine the most significant environmental effects of ocean energy harvest for tidal systems in temperate estuaries, for wave energy installations in temperate coastal areas, wave installations in sub-tropical waters, and riverine energy installations in large rivers. In addition, the National Laboratories are investigating the effects of energy removal from waves, tides and river currents using numerical modeling studies. Laboratory and field research is also underway to understand the effects of electromagnetic fields (EMF), acoustic noise, toxicity from anti-biofouling coatings, effects on benthic habitats, and physical interactions with tidal and wave devices on marine and freshwater organisms and ecosystems. Outreach and interactions with stakeholders allow the National Laboratories to understand and mitigate for use conflicts and to provide useful information for marine spatial planning at the national and regional level.

    Already 35 years are going to elapse since atomic energy industry was founded in Japan, and the positive development has been carried out in the nuclear power generation mainly with light water reactors as the base energy, as the result, now both the result of electric power generation and the technology have reached the highest level in the world. These are due to the accumulation of efforts, the preponderant assignment of able men and the positive investment for the research and development of the atomic energy industry. However, since 1985, the slowdown of power reactor development, the practical use of new type power reactors such as fast breeder reactors and the establishment of nuclear fuel cycle such as uranium enrichment and fuel reprocessing have been the new situation to be dealt with. In order to properly and flexibly cope with such change of situation, the healthy development of the atomic energy industry so as to secure the market on a certain scale and develop the business with responsibility is indispensable. The outlay of electric power industry related to atomic energy, the development of atomic energy market and the sales of mining and manufacturing industries, the trend of research and development and personnel, and the perspective and subjects of hereafter are reported.

  7. Ocean thermal energy conversion: Perspective and status

    Science.gov (United States)

    Thomas, Anthony; Hillis, David L.

    The use of the thermal gradient between the warm surface waters and the deep cold waters of tropical oceans was first proposed by J. A. d'Arsonval in 1881 and tried unsuccessfully by George Claude in 1930. Interest in Ocean Thermal Energy Conversion (OTEC) and other renewable energy sources revived in the 1970s as a result of oil embargoes. At that time, the emphasis was on large floating plants miles from shore producing 250 to 400 MW for maintained grids. When the problems of such plants became better understood and the price of oil reversed its upward trend, the emphasis shifted to smaller (10 MW) shore based plants on tropical islands. Such plants would be especially attractive if they produce fresh water as a by-product. During the past 15 years, major progress has been made in converting OTEC unknowns into knowns. Mini-OTEC proved the closed cycle concept. Cost effective heat exchanger concepts were identified. An effective biofouling control technique was discovered. Aluminum was determined to be promising for OTEC heat exchangers. Heat transfer augmentation techniques were identified, which promised a reduction on heat exchanger size and cost. Fresh water was produced by an OTEC open cycle flash evaporator, using the heat energy in the seawater itself. The current R and D emphasis is on the design and construction of a test facility to demonstrate the technical feasibility of the open cycle process. The 10 MW shore-based, closed cycle plant can be built with today's technology; with the incorporation of a flash evaporator, it will produce fresh water as well as electrical power; both valuable commodities on many tropical islands. The open cycle process has unknowns that require solution before the technical feasibility can be demonstrated. The economic viability of either cycle depends on reducing the capital costs of OTEC plants and on future trends in the costs of conventional energy sources.

    This paper tries to assess the relationship between disaggregate energy consumption and industrial output in South Africa by undertaking a cointegration analysis using annual data from 1980 to 2005. We also investigate the causal relationships between the various disaggregate forms of energy consumption and industrial production. Our results imply that industrial production and employment are long-run forcing variables for electricity consumption. Applying the [Toda, H.Y., Yamamoto, T., 1995. Statistical inference in vector autoregressions with possibly integrated processes. Journal of Econometrics 66, 225-250] technique to Granger-causality, we find bi-directional causality between oil consumption and industrial production. For the other forms of energy consumption, there is evidence in support of the energy neutrality hypothesis. There is also evidence of causality between employment and electricity consumption as well as coal consumption causing employment. (author)

    The use of energy in the industrial sectors of nations with both industrialized and developing economies will continue to be, a major source of greenhouse gas (GHG) emissions, particularly carbon dioxide. The patterns of industrial-sector energy use--energy provided primarily by the combustion of fossil fuels-have shifted both within the between countries in recent decades. Projections of future energy use and carbon-dioxide (CO 2 ) emissions suggest continued shifts in these patterns, as industrial production in developed countries stabilizes and declines, while industrial output in the developing world continues to expand. This expansion of industrial-sector activity and CO 2 emissions in developing countries presents both a challenge and an opportunity. To seize this opportunity and contribute to international efforts to mitigate global climate change, the United National Industrial Development Organization (UNIDO) recently initiated a two-phase effort to help improve the efficiency of energy-intensive industries (iron and steel, chemicals, refining, paper and pulp, and cement) in developing countries. As part of the Phase I, the authors reviewed industrial sector scenarios and to initiated development of a software-based toolkit for identifying and assessing GHG mitigating technologies. This toolkit, called IDENTIFY, is comprised of a technology inventory and a companion economic analysis tool. In addition, UNIDO commissioned institutions in India, South Africa, and Argentina to review energy use patterns and savings opportunities in selected industries across nine developing countries, and contribute to the development of the IDENTIFY toolkit. UNIDO is now preparing to launch Phase 2, which will focus on full development and dissemination of the IDENTIFY toolkit through seminars and case studies around the world. This paper describes Phase 1 of the UNIDO project

    2009-01-01

    The industrial sector is the largest user of energy in Malaysia. Industrial motors account for a major segment of total industrial energy use. Since motors are the principle energy users, different energy savings strategies have been applied to reduce their energy consumption and associated emissions released into the atmosphere. These strategies include using highly efficient motors, variable speed drive (VSD), and capacitor banks to improve the power factor. It has been estimated that there can be a total energy savings of 1765, 2703 and 3605 MWh by utilizing energy-efficient motors for 50%, 75% and 100% loads, respectively. It was also found that for different motor loads, an estimated US$115,936 US$173,019 and US$230,693 can be saved in anticipated energy costs. Similarly, it is hypothesized that a significant amount of energy can be saved using VSD and capacitor banks to reduce speed and improve the power factor, thus cutting energy costs. Moreover, a substantial reduction in the amount of emissions can be effected together with the associated energy savings for different energy savings strategies. In addition, the payback period for different energy savings strategies has been found to be reasonable in some cases.

  18. Opportunity Analysis for Recovering Energy from Industrial Waste Heat and Emissions

    United States industry consumed 32.5 Quads (34,300 PJ) of energy during 2003, which was 33.1% of total U.S. energy consumption (EIA 2003 Annual Energy Review). The U.S. industrial complex yields valuable goods and products. Through its manufacturing processes as well as its abundant energy consumption, it supports a multi-trillion dollar contribution to the gross domestic product and provides millions of jobs in the U.S. each year. Industry also yields waste products directly through its manufacturing processes and indirectly through its energy consumption. These waste products come in two forms, chemical and thermal. Both forms of waste have residual energy values that are not routinely recovered. Recovering and reusing these waste products may represent a significant opportunity to improve the energy efficiency of the U.S. industrial complex. This report was prepared for the U.S. Department of Energy Industrial Technologies Program (DOE-ITP). It analyzes the opportunity to recover chemical emissions and thermal emissions from U.S. industry. It also analyzes the barriers and pathways to more effectively capitalize on these opportunities. A primary part of this analysis was to characterize the quantity and energy value of the emissions. For example, in 2001, the industrial sector emitted 19% of the U.S. greenhouse gases (GHG) through its industrial processes and emitted 11% of GHG through electricity purchased from off-site utilities. Therefore, industry (not including agriculture) was directly and indirectly responsible for emitting 30% of the U.S. GHG. These emissions were mainly comprised of carbon dioxide (CO2), but also contained a wide-variety of CH4 (methane), CO (carbon monoxide), H2 (hydrogen), NMVOC (non-methane volatile organic compound), and other chemicals. As part of this study, we conducted a survey of publicly available literature to determine the amount of energy embedded in the emissions and to identify technology opportunities to capture and

    The ceramic industry occupies a prominent place in the Brazilian industrial context, representing about 1.0% in the GDP composition. On the other hand, it represent about 1.9% of all energy consumed in the country, and 5.8% of the energy consumed in the Brazilian industrial sector in 2014. Regarding the power consumption by the ceramic industry, most is derived from renewable sources (firewood), followed by use of fossil fuels, mainly natural gas (NG). This study was conducted to quantify the energy consumption in the production of ceramic tiles (CT), by means of experimental data obtained directly in the industry and at every step of the manufacturing process. The step of firing and sintering has the highest energy consumption, with approximately 56% of the total energy consumed. In sequence, have the atomization steps with 30% and the drying with 14%, of total energy consumption in the production of ceramic tiles, arising from the use of NG. In addition, it showed that the production of ceramic tiles by wet process has energy consumption four times the dry production process, due to the atomization step.

    1980-01-01

    A generally mushroom-shaped, open cycle OTEC system and distilled water producer which has a skirt-conduit structure extending from the enlarged portion of the mushroom to the ocean. The enlarged part of the mushroom houses a toroidal casing flash evaporator which produces steam which expands through a vertical rotor turbine, partially situated in the center of the blossom portion and partially situated in the mushroom's stem portion. Upon expansion through the turbine, the motive steam enters a shell and tube condenser annularly disposed about the rotor axis and axially situated beneath the turbine in the stem portion. Relatively warm ocean water is circulated up through the radially outer skirt-conduit structure entering the evaporator through a radially outer portion thereof, flashing a portion thereof into motive steam, and draining the unflashed portion from the evaporator through a radially inner skirt-conduit structure. Relatively cold cooling water enters the annular condenser through the radially inner edge and travels radially outwardly into a channel situated along the radially outer edge of the condenser. The channel is also included in the radially inner skirt-conduit structure. The cooling water is segregated from the potable, motive steam condensate which can be used for human consumption or other processes requiring high purity water. The expansion energy of the motive steam is partially converted into rotational mechanical energy of the turbine rotor when the steam is expanded through the shaft attached blades. Such mechanical energy drives a generator also included in the enlarged mushroom portion for producing electrical energy. Such power generation equipment arrangement provides a compact power system from which additional benefits may be obtained by fabricating the enclosing equipment, housings and component casings from low density materials, such as prestressed concrete, to permit those casings and housings to also function as a floating

  4. Thoughts on why in CESM a more poleward TOA energy imbalance favors more ocean-centric energy transport and weaker ITCZ shift responses

    Science.gov (United States)

    Yu, S.; Pritchard, M. S.

    2017-12-01

    The role of different location of top-of-atmosphere (TOA) solar forcing to the annual-mean, zonal-mean ITCZ location is examined in a dynamic ocean coupled Community Earth System Model. We observe a damped ITCZ shift response that is now a familiar response of coupled GCMs, but a new finding is that the damping efficiency is increases monotonically as the latitudinal location of forcing is moved poleward. More Poleward forcing cases exhibit weaker shifts of the annual-mean ITCZ position consistent with a more ocean-centric cross-equatorial energy partitioning response to the forcing, which is in turn linked to changes in ocean circulation, not thermodynamic structure. The ocean's dynamic response is partly due to Ekman-driven shallow overturning circulation responses, as expected from a recent theory, but also contains a significant Atlantic meridional overturning circulation (AMOC) component--which is in some sense surprising given that it is activated even in near-tropical forcing experiments. Further analysis of the interhemispheric energy budget reveals the surface heating feedback response provides a useful framework for interpreting the cross-equatorial energy transport partitioning between atmosphere and ocean. Overall, the results of this study may help explain the mixed results of the degree of ITCZ shift response to interhemispheric asymmetric forcing documented in coupled GCMs in recent years. Furthermore, the sensitive AMOC response motivates expanding current coupled theoretical frameworks on meridional energy transport partitioning to include effects beyond Ekman transport.

    Energy is the most important cost factor in the U.S petrochemical industry, defined in this guide as the chemical industry sectors producing large volume basic and intermediate organic chemicals as well as large volume plastics. The sector spent about $10 billion on fuels and electricity in 2004. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. petrochemical industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy efficient technologies that can be implemented at the component, process, facility, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the petrochemical industry is provided along with a description of the major process technologies used within the industry. Next, a wide variety of energy efficiency measures are described. Many measure descriptions include expected savings in energy and energy-related costs, based on case study data from real-world applications in the petrochemical and related industries worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers in the U.S. petrochemical industry reduce energy consumption in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of all measures--and on their applicability to different production practices--is needed to assess their cost effectiveness at individual plants.

    Tonkin, S.L.

    1999-01-01

    Various issues regarding U.S. wholesale energy marketing were discussed with particular emphasis on how energy marketing is changing industries in North America. In 1998, the energy industry reported a growth in revenue of 26 per cent despite declining natural gas prices. It was emphasized that several major competitive issues need to be addressed by industry competitors in order to operate in this unpredictable market. These issues include profitability, market volatility and mergers and acquisitions. This paper presented a list of the top 10 North American Energy marketers in 1998. Although the number of marketers in the energy sector continues to grow, it is expected that the numbers will decline significantly within three years. This will be due mostly to the continuation of major mergers and acquisitions. It was concluded that in general, energy marketing may become an even more attractive industry because of increasing operating margins. 5 tabs., 2 figs

  9. Modeling the effects of involvement and attitudes on energy industry pursuit intentions: A systems analysis of the university-industry environment

    Gross, Jordan M.

    The energy industry's struggle to attract and retain qualified employees continues to threaten the nation's economy, global competitiveness, and national security. Given the nationwide skills and labor shortage in the energy industry, this study was conducted in response to a need to identify causes of person-environment fit and its effects on engineering students' intentions to work in the energy industry after graduation. Structural equation modeling was used to examine the relationships between student inputs, environmental factors, and career-related outcomes. Two models were compared using data collected from 381 undergraduate engineering students from across the country. Results suggest that students who gained knowledge about professions in the energy industry from participating in an internship or co-op at an energy-related company perceived greater fit with the goals and values of the energy industry. In addition, this study found that students who perceive high levels of fit with the energy industry also have high industry attraction, which directly affects their energy industry pursuit intentions. Overall, this research indicates that high quality internships have the potential to increase students' perceived industry fit, which is closely tied to their career intentions. Outcomes of this study are expected to provide stakeholders with new insights to improve practices within the university-industry environment that will educate, promote, and sustain a strong energy workforce for years to come.

    The study computes and analyses the sources of the change of energy intensity of the manufacturing industries in Thailand during the period (1991–2011) using the decomposition method. The Logarithmic Mean Divisia Index is computed and the results show that the energy intensity in the period (1991–2000) increased greatly from the increased energy intensity of each industry. In the more recent period (2000–2011) the energy intensity declined a little. However the decline was mainly from the structural change effect with negligible contribution from decreased energy intensity of each industry. The findings imply the need to balance industrial restructuring policies with efforts to reduce energy intensity for a sustainable economic development. Besides, there is much room for individual industries to improve their energy efficiency. Policies on restructuring energy prices and other non-price related measures should be devised to induce individual industries, particularly the highly energy intensive ones, to reduce their energy intensity. - Highlights: • Decomposing change of energy intensity of Thai manufacturing industries, 1991–2011. • 1991–2000 energy intensity rose due to increased energy intensity of each industry. • 2000–2011 energy intensity declined due mainly to the structural change effect. • Need to balance industrial restructuring policies to reduce energy intensity

Projections of future energy use and carbon-dioxide (CO{sub 2}) emissions suggest continued shifts in these patterns, as industrial production in developed countries stabilizes and declines, while industrial output in the developing world continues to expand. This expansion of industrial-sector activity and CO{sub 2} emissions in developing countries presents both a challenge and an opportunity. To seize this opportunity and contribute to international efforts to mitigate global climate change, the United National Industrial Development Organization (UNIDO) recently initiated a two-phase effort to help improve the efficiency of energy-intensive industries (iron and steel, chemicals, refining, paper and pulp, and cement) in developing countries. As part of the Phase I, the authors reviewed industrial sector scenarios and to initiated development of a software-based toolkit for identifying and assessing GHG mitigating technologies. This toolkit, called IDENTIFY, is comprised of a technology inventory and a companion economic analysis tool. In addition, UNIDO commissioned institutions in India, South Africa, and Argentina to review energy use patterns and savings opportunities in selected industries across nine developing countries, and contribute to the development of the IDENTIFY toolkit. UNIDO is now preparing to launch Phase 2, which will focus on full development and dissemination of the IDENTIFY toolkit through seminars and case studies around the world. This paper describes Phase 1 of the UNIDO project.

  12. Cyber Attacks: A New Threat to the Energy Industry

    The Network and Information Security (NIS) Directive has been adopted on July 6, 2016 by the European Parliament, three years after the initial proposal by the European Commission. It paves the way for a much needed common cyber security strategy within the EU. This Edito explains the reasons why the energy industry is particularly vulnerable to cyber- attacks, and what tools this new directive brings about to protect European critical infrastructures. In about two decades, the energy industry has been deeply transformed by the digital revolution, which penetrated companies' commercial, administrative and financial branches, but also their industrial systems. From the optimization of electric grids to the precision of oil drilling, information and communication technologies (ICT) are now essential to every stage of energy production, transport and distribution processes. Data mining and analysis are increasingly considered as the energy sector's new 'black gold', and generate new activities just like the platform Predix, designed by General Electric to help energy companies (among others) collect and analyze industrial data. This silent revolution offers countless economic opportunities and paves the way for a better resource distribution and use. But it also puts physical energy infrastructures at risk

    The Russian energy industry by totality of politic, social and economic circumstances has entered into the sharpest crisis. Development of energy industry has practically ceased, it has appeared a decline in electricity , oil and coal production. However it has been accumulated a vast intact potential for energy conservation and the change of energy consuming equipment in USSR by the best models of the world could reduce the present annual consumption by about 500 millions.tonnes of coal equivalent

    It is pointed out that New Zealand industry has been identified as putting little effort into energy conservation. An energy conservation campaign in industry to increase efficiency and reduce wastage could have major benefits for New Zealand as a whole. Little progress in implementing energy conservation techniques in industry is apparent at present. Business decisions are in the main motivated by profits. Because of the low place of energy in industry's costs of production, seen as a single factor, it hardly rates greater priority over other established production costs. A need to integrate energy costs and material costs is apparent. The need for education is obvious, now, with cheap and limitless energy no longer existing.

    2010-10-06

    The U.S. Department of Energy (US DOE) has mobilized its National Laboratories to address the broad range of environmental effects of ocean and river energy development. The National Laboratories are using a risk-based approach to set priorities among environmental effects, and to direct research activities. Case studies will be constructed to determine the most significant environmental effects of ocean energy harvest for tidal systems in temperate estuaries, for wave energy installations in temperate coastal areas, wave installations in sub-tropical waters, and riverine energy installations in large rivers. In addition, the National Laboratories are investigating the effects of energy removal from waves, tides and river currents using numerical modeling studies. Laboratory and field research is also underway to understand the effects of electromagnetic fields (EMF), acoustic noise, toxicity from anti-biofouling coatings, effects on benthic habitats, and physical interactions with tidal and wave devices on marine and freshwater organisms and ecosystems. Outreach and interactions with stakeholders allow the National Laboratories to understand and mitigate for use conflicts and to provide useful information for marine spatial planning at the national and regional level.

  17. Graphene for energy solutions and its industrialization

    Wei, Di; Kivioja, Jani

    2013-10-01

    Graphene attracts intensive interest globally across academia and industry since the award of the Nobel Prize in Physics 2010. Within the last half decade, there has been an explosion in the number of scientific publications, patents and industry projects involved in this topic. On the other hand, energy is one of the biggest challenges of this century and related to the global sustainable economy. There are many reviews on graphene and its applications in various devices, however, few of the review articles connect the intrinsic properties of graphene with its energy. The IUPAC definition of graphene refers to a single carbon layer of graphite structure and its related superlative properties. A lot of scientific results on graphene published to date are actually dealing with multi-layer graphenes or reduced graphenes from insulating graphene oxides (GO) which contain defects and contaminants from the reactions and do not possess some of the intrinsic physical properties of pristine graphene. In this review, the focus is on the most recent advances in the study of pure graphene properties and novel energy solutions based on these properties. It also includes graphene metrology and analysis of both intellectual property and the value chain for the existing and forthcoming graphene industry that may cause a new `industry revolution' with the strong and determined support of governments and industries across the European Union, U. S., Asia and many other countries in the world.

    2004-12-01

    Ocean wave activity is a major enviromental forcing agent of the ice-rich sediments that comprise large sections of the arctic coastal margins. While it is instructive to possess information about the wind regimes in these regions, direct application to geomorphological and engineering needs requires knowledge of the resultant wave-energy regimes. Wave energy information has been calculated at the regional scale using adjusted reanalysis model windfield data. Calculations at this scale are not designed to account for local-scale coastline/bathymetric irregularities and variability. Results will be presented for the circumpolar zones specified by the Arctic Coastal Dynamics Project.

    This report investigates the state of the US textile industry in terms of energy consumption and conservation. Specific objectives were: To update and verify energy and materials consumption data at the various process levels in 1984; to determine the potential energy savings attainable with current (1984), state-of-the-art, and future production practices and technologies (2010); and to identify new areas of research and development opportunity that will enable these potential future savings to be achieved. Results of this study concluded that in the year 2010, there is a potential to save between 34% and 53% of the energy used in current production practices, dependent on the projected technology mix. RandD needs and opportunities were identified for the industry in three categories: process modification, basic research, and improved housekeeping practices that reduce energy consumption. Potential RandD candidates for DOE involvement with the private sector were assessed and selected from the identified list.

  3. Do urbanization and industrialization affect energy intensity in developing countries?

    Sadorsky, Perry

    2013-01-01

    Against a backdrop of concerns about climate change, peak oil, and energy security issues, reducing energy intensity is often advocated as a way to at least partially mitigate these impacts. This study uses recently developed heterogeneous panel regression techniques like mean group estimators and common correlated effects estimators to model the impact that income, urbanization and industrialization has on energy intensity for a panel of 76 developing countries. In the long-run, a 1% increase in income reduces energy intensity by − 0.45% to − 0.35%. Long-run industrialization elasticities are in the range 0.07 to 0.12. The impact of urbanization on energy intensity is mixed. In specifications where the estimated coefficient on urbanization is statistically significant, it is slightly larger than unity. The implications of these results for energy policy are discussed. - Highlights: ► The impact of urbanization and industrialization on energy intensity is modeled. ► Use recently developed heterogeneous panel regression techniques ► The model is tested on a panel of developing countries. ► Income has a negative impact on energy intensity. ► Industrialization has a positive impact on energy intensity

  4. The forest products industry at an energy/climate crossroads

    2010-01-01

    Transformational energy and climate policies are being debated worldwide that could have significant impact upon the future of the forest products industry. Because woody biomass can produce alternative transportation fuels, low-carbon electricity, and numerous other 'green' products in addition to traditional paper and lumber commodities, the future use of forest resources is highly uncertain. Using the National Energy Modeling System (NEMS), this paper assesses the future of the forest products industry under three possible U.S. policy scenarios: (1) a national renewable electricity standard, (2) a national policy of carbon constraints, and (3) incentives for industrial energy efficiency. In addition, we discuss how these policy scenarios might interface with the recently strengthened U.S. renewable fuels standards. The principal focus is on how forest products including residues might be utilized under different policy scenarios, and what such market shifts might mean for electricity and biomass prices, as well as energy consumption and carbon emissions. The results underscore the value of incentivizing energy efficiency in a portfolio of energy and climate policies in order to moderate electricity and biomass price escalation while strengthening energy security and reducing CO 2 emissions. - Research highlights: →Transformational energy and climate policies such as a national renewable electricity standard, a national policy of carbon constraints, and incentives for industrial energy efficiency could have significant impact upon the future of the forest products industry. →Each policy scenario reduces CO 2 emissions over time, compared to the business-as-usual forecast, with the carbon constrained policy producing the largest decline. As a package, the three policies together could cut CO 2 emissions from the electricity sector by an estimated 41% by 2030. →This study underscores the value of incentivizing energy efficiency in a portfolio of energy and

    Castelli, V.J. (ed.)

    1979-05-01

    Of the many foreseeable problems confronting economical ocean thermal energy conversion operation, two major items are the deterioration of the structural and functional components, which prevents efficient operation, and the biofouling of the surfaces, which adds excess weight to the floating ocean platform. The techniques required for effective long-term control of deterioration and corrosion have been investigated actively for many years, and successful solutions for most situations have been developed. For the most part, these solutions can be directly transferred to the ocean thermal energy conversion plant. The majority of problems in these areas are expected to be associated with scale-up and will require some advanced development due to the immensity of the ocean thermal energy conversion platform. Current antifouling control systems are not effective for long-term fouling prevention. Commercially available antifouling coatings are limited to a 3-year service life in temperate waters, and even shorter in tropical waters. However, underwater cleaning techniques and some fouling-control systems presently being used by conventional power plants may find utility on an ocean thermal energy conversion plant. In addition, some recent major advances in long-term antifouling coatings sponsored by the Navy may be applicable to ocean thermal energy conversion. 132 references.

  7. How Can China Lighten Up? Urbanization, Industrialization and Energy Demand Scenarios

    Energy Technology Data Exchange (ETDEWEB)

    Aden, Nathaniel T.; Zheng, Nina; Fridley, David G.

    2009-07-01

    Urbanization has re-shaped China's economy, society, and energy system. Between 1990 and 2007 China added 290 million new urban residents, bringing the total urbanization rate to 45%. This population adjustment spurred energy demand for construction of new buildings and infrastructure, as well as additional residential use as rural biomass was replaced with urban commercial energy services. Primary energy demand grew at an average annual rate of 10% between 2000 and 2007. Urbanization's effect on energy demand was compounded by the boom in domestic infrastructure investment, and in the export trade following World Trade Organization (WTO) accession in 2001. Industry energy consumption was most directly affected by this acceleration. Whereas industry comprised 32% of 2007 U.S. energy use, it accounted for 75% of China's 2007 energy consumption. Five sub-sectors accounted for 78% of China's industry energy use in 2007: iron and steel, energy extraction and processing, chemicals, cement, and non-ferrous metals. Ferrous metals alone accounted for 25% of industry and 18% of total primary energy use. The rapid growth of heavy industry has led China to become by far the world's largest producer of steel, cement, aluminum, and other energy-intensive commodities. However, the energy efficiency of heavy industrial production continues to lag world best practice levels. This study uses scenario analysis to quantify the impact of urbanization and trade on industrial and residential energy consumption from 2000 to 2025. The BAU scenario assumed 67% urbanization, frozen export amounts of heavy industrial products, and achievement of world best practices by 2025. The China Lightens Up (CLU) scenario assumed 55% urbanization, zero net exports of heavy industrial products, and more aggressive efficiency improvements by 2025. The five dominant industry sub-sectors were modeled in both scenarios using a LEAP energy end-use accounting model. The results of

    With its GDP growing at an average rate of 9.8% for the last seventeen years, China has the world's fastest growing economy. This rapid pace of growth and industrialization has caused economic strain because fuel production cannot keep pace with demand, If China allows this situation to continue, significant oil imports will be necessary. In 1993, the industrial sector contributed 56% to China's GDP and consumed 61% of the total final energy. The industrial sector will remain the largest energy consumer in China well into the next century. According to China's Ninth Five-Year Plan (1996--2000), China will strengthen its ability to develop new products and will use technological advancement to promote industrial development. The Plan calls for special attention in four major areas: microelectronics technology, digital technology, software technology, and network technology. Given China's emphasis on developing light industries and on improving industrial sector energy efficiency, it is important to study the future energy demand of the industrial sector. Two scenarios for future energy requirements are studied through the year 2015: a Business As Usual (BASU) scenario and an Energy Efficient (EE) scenario. The study evaluates China's current economic reform policies and energy efficiency policies. The results of this evaluation are used to assign appropriate growth rates to industrial GDP and the industrial energy intensity for both scenarios. Results from the two scenarios are compared and analyzed

    Results of field studies of underwater dynamic noise energy flux directivity at two wind speeds, 6 m/s and 12 m/s, in the 400 Hz to 700 Hz frequency band in the deep open ocean are presented. The measurements were made by a freely drifting telemetric combined system at 500 m depth. Statistical characteristics of the horizontal and vertical dynamic noise energy flux directivity are considered as functions of wind speed and direction. Correlation between the horizontal dynamic noise energy flux direction and that of the wind was determined; a mechanism of the horizontal dynamic noise energy flux generation is related to the initial noise field scattering on ocean surface waves.

    Climate change mitigation, if intelligently undertaken, can stimulate economic growth. The main tools available for this task are energy efficiency, renewable energy, and clean energy technologies and services, which are collectively known as sustainable energy. To unleash this potential, the US and other governments need the full cooperation of the sustainable energy industry. This industry knows more than most other about turning energy-related pollution prevention into profits. If engaged, they can help: (1) Identify the economic benefits of greenhouse gas mitigation; (2) Identify barriers to the implementation of greenhouse gas mitigation projects; (3) Develop policies and measures to overcome these barriers; and (4) Implement greenhouse gas mitigation projects. 7 refs.

    Global awareness on energy security and climate change has created much interest in assessing economy-wide energy efficiency performance. A number of previous studies have contributed to evaluate energy efficiency performance using different analytical techniques among which data envelopment analysis (DEA) has recently received increasing attention. Most of DEA-related energy efficiency studies do not consider undesirable outputs such as CO 2 emissions in their modeling framework, which may lead to biased energy efficiency values. Within a joint production framework of desirable and undesirable outputs, in this paper we construct both static and dynamic energy efficiency performance indexes for measuring industrial energy efficiency performance by using several environmental DEA models with CO 2 emissions. The dynamic energy efficiency performance indexes have further been decomposed into two contributing components. We finally apply the indexes proposed to assess the industrial energy efficiency performance of different provinces in China over time. Our empirical study shows that the energy efficiency improvement in China's industrial sector was mainly driven by technological improvement. - Highlights: ► China's industrial energy efficiency is evaluated by DEA models with CO 2 emissions. ► China's industrial energy efficiency improved by 5.6% annually since 1997. ► Industrial energy efficiency improvement in China was mainly driven by technological improvement.

    The mission of the Office of Industrial Technologies (OIT), within the Office of Energy Efficiency and Renewable Energy, is to develop and deploy advanced energy efficiency, renewable energy, and pollution-prevention technologies, through partnerships with industry, government, and non-governmental organizations. OIT's objectives have evolved and broadened over nearly two decades, continually responding to a changing energy situation and shifting national priorities. Today, the key focus of the OIT programs is the Industries of the Future approach. This strategy of close collaboration with industry catalyzes and facilitates technology development and transfer efforts in seven manufacturing industries that together account for over 80% of the energy used and over 80% of the wastes produced by the manufacturing sector. In this approach senior level industry groups develop a future vision of their industry and a technology roadmap to attain the vision. DOE helps facilitate this process and partners with industry to identify and pursue an advanced technology R and D portfolio. The seven industries are aluminum, chemicals, forest products, glass, metalcasting, petroleum refining, and steel. In managing all its activities, OIT draws upon program support provided primarily by national Laboratories, universities, and private-sector research organizations throughout the country that have the diverse and specialized expertise needed to develop advanced industrial technologies. Approximately 78 industrial technologies developed with Office of Industrial Technology (OIT) support have successfully entered commercial markets. These technologies have saved a cumulative total of almost 900 trillion Btu, representing a new production cost savings of over $1.8 billion. These dollar savings represent the net total value of all energy saved by technologies developed with OIT support minus the net cost to industry of using the technologies (including capital costs, operating and

    Over the last 40 years, the fermentation industry has provided facility planners, plant operators and environmental engineers with a wide range of residuals management challenges and resource/energy recovery opportunities. In response, the industry has helped pioneer the use of a number of innovative resource and energy recovery technologies. Production of animal feed supplements, composts, fertilizers, soil amendments, commercial baking additives and microbial protein materials have all been detailed in the literature. In many such cases, recovery of by-products significantly reduces the need for treatment and disposal facilities. Stable, reliable anaerobic biological treatment processes have also been developed to recover significant amounts of energy in the form of methane gas. Alternatively, dewatered or condensed organic fermentation industry residuals have been used as fuels for incineration-based energy recovery systems. The sale or use of recovered by-products and/or energy can be used to offset required processing costs and provide a technically and environmentally viable alternative to traditional treatment and disposal strategies. This review examines resource recovery options currently used or proposed for fermentation industry residuals and the conditions necessary for their successful application. (author).

    Conclusion: The job of the Energy Industry Law is to secure for the government the necessary influence without endangering the private enterprise structure of the power supply industry. The Energy Industry Law has achieved satisfactory results. For it is in no way obvious that a different system would have achieved lower prices or a level of capacity more exactly tuned to sales. The powers of objection and prohibition contained in Sect. 4 of the Energy Industry Law are limited to (all) circumstances which influence the reliability and cheapness of supply. These powers should not be used to promote a nuclear power phaseout, introduce renewable energy sources, promote the protection of the environment, to counter the demand for cheapness of supply, to enforce power-heat cogeneration and to enforce decentralisation.

    The industrial sector is responsible for a significant share of global energy use and carbon dioxide (CO 2 ) emissions. Energy efficiency is commonly seen as the most cost-effective, least-polluting, and most readily-accessible industrial energy saving option available in the industrial sector worldwide. Capturing the full extent of these potential end-use energy efficiency improvements rapidly is essential if the world is to be on a path to stabilise greenhouse gas (GHG) concentrations to a level that would prevent dangerous anthropogenic interference with the climate system. In the International Energy Agency (IEA) 450 parts per million stabilisation scenario, over a quarter of all energy efficiency gains need to come from the industrial sector by 2050, largely by changing the pattern of industrial energy use. The reduction potential estimated by IEA and the Intergovernmental Panel on Climate Change (IPCC) for five energy-intensive industrial sub-sectors ranges from about 10 to 40 per cent, depending upon the sector. There is significant potential to reduce, at low or no cost, the amount of energy used to manufacture most commodities. Many policies and programmes - at a national level - have already demonstrated significant improvements in industrial energy efficiency. The associate reduction in energy needs often also improves economic competitiveness as well as mitigates GHG emissions. However, at an international level, approaches such as the Clean Development Mechanism (CDM) are not yet delivering the expected energy efficiency improvements. Existing and effective industrial energy efficiency policies and measures could be replicated at a global level. Key elements of those policies and measures include increasing facility management attention to the issue of energy efficiency; promoting the dissemination of information, practice, and tools; increasing the auditing and implementation capacity; and developing the market for industrial energy efficiency

    Constraining photosynthetic energy conversion efficiency in nature is challenging. In principle, two yield measurements must be made simultaneously: photochemistry, fluorescence and/or thermal dissipation. We constructed two different, extremely sensitive and precise active fluorometers: one measures the quantum yield of photochemistry from changes in variable fluorescence, the other measures fluorescence lifetimes in the picosecond time domain. By deploying the pair of instruments on eight transoceanic cruises over six years, we obtained over 200 000 measurements of fluorescence yields and lifetimes from surface waters in five ocean basins. Our results revealed that the average quantum yield of photochemistry was approximately 0.35 while the average quantum yield of fluorescence was approximately 0.07. Thus, closure on the energy budget suggests that, on average, approximately 58% of the photons absorbed by phytoplankton in the world oceans are dissipated as heat. This extraordinary inefficiency is associated with the paucity of nutrients in the upper ocean, especially dissolved inorganic nitrogen and iron. Our results strongly suggest that, in nature, most of the time, most of the phytoplankton community operates at approximately half of its maximal photosynthetic energy conversion efficiency because nutrients limit the synthesis or function of essential components in the photosynthetic apparatus.This article is part of the themed issue 'Enhancing photosynthesis in crop plants: targets for improvement'. © 2017 The Author(s).

  19. Nuclear dual-purpose plants for industrial energy

    Klepper, O.H.

    1976-01-01

    One of the major obstacles to extensive application of nuclear power to industrial heat is the difference between the relatively small energy requirements of individual industrial plants and the large thermal capacity of current power reactors. A practical way of overcoming this obstacle would be to operate a centrally located dual-purpose power plant that would furnish process steam to a cluster of industrial plants, in addition to generating electrical power. The present study indicates that even relatively remote industrial plants could be served by the power plant, since it might be possible to convey steam economically as much as ten miles or more. A survey of five major industries indicates a major potential market for industrial steam from large nuclear power stations

    The energy-utilization over a 10-year period (1994-2003) has been analysed for the South African industrial sector, which consumes more primary energy than any other sector of the economy. Four principal sub-sectors, namely iron and steel, chemical and petrochemical, mining and quarrying, and non-ferrous metals/non-metallic minerals were considered in this study. Primary-energy utilization data were used to calculate the weighted mean energy and exergy efficiencies for the sub-sectors and then overall values for the industrial sector were obtained. The results indicate that exergy efficiency is considerably lower than energy efficiency in all the sub-sectors, particularly in mining and quarrying processes, for which the values were approximately 83% and 16%, respectively. The performance of exergy utilization in the industrial sector can be improved by introducing various conservation strategies. Results from this study were compared with those for other countries

    This report presents an econometric analysis of industrial companies demand for energy. The effect of energy taxes, energy agreements and subsidies to investments in energy efficiency, which have been applied as policy instruments in Denmark since 1993, is also quantified. The econometric analysis is based on an extensive database, which contains information on industrial companies consumption of energy and their value added in a number of years covering the period 1983 to 1997 (information from the years 1983, 1985, 1988, 1990, 1993, 1995, 1996 and 1997 is included). The database has been constructed by combining information from different registers in Statistics Denmark. The database contains information on the majority of all existing industrial companies with more than 20 employees (from 1995 to 1997 primary data on energy consumption were only collected for half the industrial companies with 20-50 employees). The database has a panel (longitudinal) nature, where each industrial company can be followed over time. This makes it possible to compare energy consumption in companies before and after they have been given a subsidy to invest in energy efficiency or entered an energy agreement with the Danish Energy Agency. The econometric analysis utilises the panel nature of the data by relying on so-called fixed effect estimators. (EHS)

    This market survey for Germany is on the subject of renewable energy and energy efficient constructing and housing improvement. In order to meet sectoral or thematic information needs of Dutch exporting industries and investing companies, the EVD facilitates the realisation of up-to-date market surveys on promising markets in selected countries. The requested study is very relevant for the Dutch exporting industry, as the German building and construction market is of increasing importance to the Dutch building, installation and equipment building sector. Moreover the German market is a European innovator on renewable energy (RE) and energy efficient (EE) homes or even so-called 'passive' houses. The developments in the German market can guide the Dutch industry in the development of their export strategies. The main target groups for the market surveys are small- and medium-sized enterprises (SMEs) in the Netherlands. Interesting groups among these SMEs are those enterprises that start their business on a foreign market [nl

    Nuclear power and solar photovoltaic energy conversion often compete for policy support that governs economic viability. This paper compares current subsidization of the nuclear industry with providing equivalent support to manufacturing photovoltaic modules. Current U.S. indirect nuclear insurance subsidies are reviewed and the power, energy and financial outcomes of this indirect subsidy are compared to equivalent amounts for indirect subsidies (loan guarantees) for photovoltaic manufacturing using a model that holds economic values constant for clarity. The preliminary analysis indicates that if only this one relatively ignored indirect subsidy for nuclear power was diverted to photovoltaic manufacturing, it would result in more installed power and more energy produced by mid-century. By 2110 cumulative electricity output of solar would provide an additional 48,600 TWh over nuclear worth $5.3 trillion. The results clearly show that not only does the indirect insurance liability subsidy play a significant factor for nuclear industry, but also how the transfer of such an indirect subsidy from the nuclear to photovoltaic industry would result in more energy over the life cycle of the technologies. - Highlights: → The indirect insurance liability subsidy has been quantified over the life cycle of the U.S. nuclear fleet. → It was found to play a significant factor in the economics of the nuclear industry. → A transfer of such an indirect subsidy from the nuclear to photovoltaic industry would result in significantly more energy over the life cycle of the technologies.

    There are a large number of energy resource in Kalimantan such as coal, oil, CBM, gas and nuclear. While the electricity consumption still low. That condition caused by the bad energy planning. The aim of the study are to know the number and the ability of energy resource to supply the energy demand that support the growth of Kalimantan industry. The methodology are collecting and processing data through calculation using MESSAGE Program. The result is energy resource in Kalimantan can support Kalimantan energy independence and industry growth in Kalimantan. The coal resource is 34,814 million ton consumption 835 million ton, gas resource is 31,814 BSCF consumption 3,281 BSCF, Oil resource is 920 MMSTB consumption 4406 MMSTB, CBM resource is 210 TCF consumption 2.1 TCF, U 3 O 8 resource is 12,409 ton consumption zero. Whereas for hydro and biomass, the resource are 256 and 138 MWyr, the maximum consumption 185 and 126 MWyr every year. Oil consumption will exceed the resource so need import from other island or replaced by others energy that have large resource such as gas, CBM, or coal. Potency to make cleaner environment can be done by used nuclear energy. (author)

    Conservation supply curves are a common tool in economic analysis. As such, they provide an important opportunity to include a non-linear representation of technology and technological change in economy-wide models. Because supply curves are closely related to production isoquants, we explore the possibility of using bottom-up technology assessments to inform top-down representations of energy models of the U.S. economy. Based on a recent report by LBNL and ACEEE on emerging industrial technologies within the United States, we have constructed a supply curve for 54 such technologies for the year 2015. Each of the selected technologies has been assessed with respect to energy efficiency characteristics, likely energy savings by 2015, economics, and environmental performance, as well as needs for further development or implementation of the technology. The technical potential for primary energy savings of the 54 identified technologies is equal to 3.54 Quads, or 8.4 percent of the assume d2015 industrial energy consumption. Based on the supply curve, assuming a discount rate of 15 percent and 2015 prices as forecasted in the Annual Energy Outlook2002, we estimate the economic potential to be 2.66 Quads - or 6.3 percent of the assumed forecast consumption for 2015. In addition, we further estimate how much these industrial technologies might contribute to standard reference case projections, and how much additional energy savings might be available assuming a different mix of policies and incentives. Finally, we review the prospects for integrating the findings of this and similar studies into standard economic models. Although further work needs to be completed to provide the necessary link between supply curves and production isoquants, it is hoped that this link will be a useful starting point for discussion with developers of energy-economic models.

    China's energy supply becomes more serious nowadays and the development of bio-energy becomes a major trend. Large oil companies have superb technology, rich experience and outstanding talent, as well as better sales channels for energy products, which can make full use of their own advantages to achieve the efficient complementary of exist energy and bio-energy. Therefore, large oil companies have the advantages of developing bio-energy. Bio-energy development in China is in the initial stage. There exist some problems such as available land, raw material supply, conversion technologies and policy guarantee, which restrict bio-energy from industrialized development. According to the above key issues, this article proposes suggestions and methods, such as planting energy plant in the marginal barren land to guarantee the supply of bio-energy raw materials, cultivation of professional personnel, building market for bio-energy counting on large oil companies' rich experience and market resources about oil industry, etc, aimed to speed up the industrialized process of bio-energy development in China.

    The reserves of fossil fuels which currently respond to the major part of world energy requirements are being running out very fast. Because it is forecasted that reserves of some fossil fuels like oil and natural gas will come to an end in the second half of this century, exploiting all energy resources in an efficient manner has great importance. Throughout the world where the energy demand grows continuously but the resources decrease gradually, many types of programs are implemented to provide efficient energy use. In Turkey, although there have been some efforts in last two decades, the importance of the issue could not be undersood yet. Turkey'sgeneral energy policy still focuses on supply security and finding ways to meet the growing demand, rather than decreasing the demand by energy efficiency. In this study, the possible opportunities and benefits that Turkey would gain by energy efficiency is pointed out. The studies about energy efficiency which have been conducted in the world and Turkey are examined. The measurement that can be taken in the sectors such as industry, power plants, buildings, transportation and the utilities of these measures for energy economy are indicated. The successful practices of energy efficiency studies in various countries, the state of some countries which pioneer efficiency implementations. Turkey's situation in energy in the light of basic indicators such as energy consumption per capita and enrgy intensity, the energy efficiency studies that have been done and should be done in various sectors of Turkey are also discussed in this thesis. Turkish industry's energy comsumption is analyzed as a seperate chapter by taking into consideration energy efficiency, energy intensity and energy resources. The general energy consumption and energy intensity tendencies of main manufacturing industries between 1995 and 2002 are explored and resource utilization ratios are investigated. This chapter provides to find out what kind of

    The industrial boilers in China are featured by large quantity, wide distribution, high energy consumption and heavy environmental pollution, which are key problems faced by energy conservation and environmental protection in China. Meanwhile, industrial boilers are important equipment for national economy and people’s daily life, and energy conservation gets through all segments from type selection, purchase, installation and acceptance to fuel management, operation, maintenance and service. China began to implement such national mandatory standards and regulations for industrial boiler as GB24500-2009 The Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades of Industrial Boilers and TSG G002-2010 Supervision Regulation on Energy-Saving Technology for Boilers since 2009, which obviously promote the development of energy conservation of industrial boilers, but there are also some problems with the rapid development of technologies for energy conservation of industrial boilers. In this paper, the implementation of energy efficiency standards for industrial boilers in China and the significance are analyzed based on survey data, and some suggestions are proposed for the energy efficiency standards for industrial boilers.

    Typically, industrial waste treatment costs a large amount of capital, and creates environmental concerns as well. A sound alternative for treating these industrial wastes is anaerobic digestion. This technique reduces environmental pollution, and recovers renewable energy from the organic fraction of those selected industrial wastes, mostly in the form of biogas (methane). By applying anaerobic technique, selected industrial wastes could be converted from cash negative materials into economic energy feed stocks. In this study, three kinds of industrial wastes (paper mill wastes, brown grease, and corn-ethanol thin stillage) were selected, their performance in the anaerobic digestion system was studied and their applicability was investigated as well. A pilot-scale system, including anaerobic section (homogenization, pre-digestion, and anaerobic digestion) and aerobic section (activated sludge) was applied to the selected waste streams. The investigation of selected waste streams was in a gradually progressive order. For paper mill effluents, since those effluents contain a large amount of recalcitrant or toxic compounds, the anaerobic-aerobic system was used to check its treatability, including organic removal efficiency, substrate utilization rate, and methane yield. The results showed the selected effluents were anaerobically treatable. For brown grease, as it is already well known as a treatable substrate, a high rate anaerobic digester were applied to check the economic effect of this substrate, including methane yield and substrate utilization rate. These data from pilot-scale experiment have the potential to be applied to full-scale plant. For thin stillage, anaerobic digestion system has been incorporated to the traditional ethanol making process as a gate-to-gate process. The performance of anaerobic digester was applied to the gate-to-gate life-cycle analysis to estimate the energy saving and industrial cost saving in a typical ethanol plant.

    The implementation of electric energy substitution by enterprises plays an important role in promoting the development of energy conservation and emission reduction in china. In order to explore alternative energy potential of industrial enterprises, to simulate and analyze the process of industrial enterprises, identify high energy consumption process and equipment, give priority to alternative energy technologies, and determine the enterprise electric energy substitution potential predictive value, this paper constructs the evaluation model of the influence factors of the electric energy substitution potential of industrial enterprises, and uses the combined weight method to determine the weight value of the evaluation factors to calculate the target value of the electric energy substitution potential. Taking the iron and steel industry as an example, this method is used to excavate the potential. The results show that the method can effectively tap the potential of the electric power industry

    Global maps of the maximum bottom concentration, thickness, and integrated particle mass in benthic nepheloid layers are published here to support collaborations to understand deep ocean sediment dynamics, linkage with upper ocean dynamics, and assessing the potential for scavenging of adsorption-prone elements near the deep ocean seafloor. Mapping the intensity of benthic particle concentrations from natural oceanic processes also provides a baseline that will aid in quantifying the industrial impact of current and future deep-sea mining. Benthic nepheloid layers have been mapped using 6,392 full-depth profiles made during 64 cruises using our transmissometers mounted on CTDs in multiple national/international programs including WOCE, SAVE, JGOFS, CLIVAR-Repeat Hydrography, and GO-SHIP during the last four decades. Intense benthic nepheloid layers are found in areas where eddy kinetic energy in overlying waters, mean kinetic energy 50 m above bottom (mab), and energy dissipation in the bottom boundary layer are near the highest values in the ocean. Areas of intense benthic nepheloid layers include the Western North Atlantic, Argentine Basin in the South Atlantic, parts of the Southern Ocean and areas around South Africa. Benthic nepheloid layers are weak or absent in most of the Pacific, Indian, and Atlantic basins away from continental margins. High surface eddy kinetic energy is associated with the Kuroshio Current east of Japan. Data south of the Kuroshio show weak nepheloid layers, but no transmissometer data exist beneath the Kuroshio, a deficiency that should be remedied to increase understanding of eddy dynamics in un-sampled and under-sampled oceanic areas.

    Given China's heavy reliance on fuel energy and the dominance of its industrial sector in the economy, improving energy efficiency remains one of the practical means for the country to decrease energy intensity and to fulfill its commitment made at the Copenhagen Climate Change Conference to achieve a 40-45 percent reduction in CO 2 emission intensity by 2020. This study investigates the impact of exports on industrial energy intensity to explore the possibility of reducing energy intensity through greater exports. A panel varying-coefficient regression model with a dataset of China's 20 industrial sub-sectors over 1999-2007 suggests that in general, greater exports aggravate energy intensity of the industrial sector and that great divergences exist in the impact of exports on energy intensity across sub-sectors. A panel threshold model further estimates the thresholds for the major determinants of energy intensity: exports, input in technological innovations, and Foreign Direct Investment (FDI) intensity. Given the great differences in specific sub-sector characteristics and the changing roles played by different factors across sub-sectors, there is no general export policy that would work for all sub-sectors in reducing sub-sector energy intensity. Instead, policies and measures aiming to encourage more efficient use of energy should take into full consideration the characteristics and situations of individual sub-sectors. - Research highlights: → We examine the impact of exports on industrial energy intensity in China. → Greater exports increase industrial energy intensity as a whole. → Divergences exist in the impact of exports on energy intensity across sub-sectors. → China should discard policies encouraging exports at the cost of energy efficiency. → Export policy to reduce energy intensity should cater to sub-sector characteristics.

    Ocean heat content (OHC) change contributes substantially to global sea level rise, also is a key metric of the ocean/global energy budget, so it is a vital task for the climate research community to estimate historical OHC. While there are large uncertainties regarding its value, here we review the OHC calculation by using the historical global subsurface temperature dataset, and discuss the sources of its uncertainty. The presentation briefly introduces how to correct to the systematic biases in expendable bathythermograph (XBT) data, a alternative way of filling data gaps (which is main focus of this talk), and how to choose a proper climatology. A new reconstruction of historical upper (0-700 m) OHC change will be presented, which is the Institute of Atmospheric Physics (IAP) version of historical upper OHC assessment. The authors also want to highlight the impact of observation system change on OHC calculation, which could lead to bias in OHC estimates. Furthermore, we will compare the updated observational-based estimates on ocean heat content change since 1970s with CMIP5 results. This comparison shows good agreement, increasing the confidence of the climate models in representing the climate history.

    Energy efficiency in industry plays key roles in improving energy security, environmental sustainability and economic performance. It is particularly important in strategies to mitigate climate change. The evidence of great potential for cost-effective efficiency-derived reductions in industrial energy use and greenhouse gas (GHG) emissions have prompted governments to implement numerous policies and measures aimed at improving their manufacturing industries' energy efficiency. What can be learned from these many and varied initiatives? This paper provides foundation for policy analysis for enhancing energy efficiency and conservation in industry, by surveying more than 300 policies, encompassing about 570 measures, implemented by governments in IEA countries, Brazil, China, India, Mexico, Russia and South Africa. It outlines the measures' main features, their incidence of use, and their connections with specific technical actions and key stakeholders (i.e., how and where measures affect the energy efficiency of industry). It also examines the key features underlying the measures' success: (1) potential to reduce energy use and CO 2 emissions cost-efficiently; (2) ease of policy development, execution and assessment and (3) ancillary societal effects. - Highlights: → Provides foundation for policy analysis for energy efficiency in industry. → Surveys more than 300 policies and their trends, of mainly IEA countries. → Outlines measures' features, incidence of use, technical actions and stakeholders. → Examines the key features underlying the measures' success.

  18. Accounting for asymmetric price responses and underlying energy demand trends in OECD industrial energy demand

    2014-01-01

    This paper explores the way technical progress and improvements in energy efficiency are captured when modelling OECD industrial energy demand. The industrial sectors of the developed world involve a number of different practices and processes utilising a range of different technologies. Consequently, given the derived demand nature of energy, it is vital when modelling industrial energy demand that the impact of technical progress is appropriately captured. However, the energy economics literature does not give a clear guide on how this can be achieved; one strand suggests that technical progress is ‘endogenous’ via asymmetric price responses whereas another strand suggests that it is ‘exogenous’. More recently, it has been suggested that potentially there is a role for both ‘endogenous’ technical progress and ‘exogenous’ technical progress and consequently the general model should be specified accordingly. This paper therefore attempts to model OECD industrial energy demand using annual time series data over the period 1962–2010 for 15 OECD countries. Using the Structural Time Series Model framework, the general specifications allow for both asymmetric price responses (for technical progress to impact endogenously) and an underlying energy demand trend (for technical progress and other factors to impact exogenously, but in a non-linear way). The results show that almost all of the preferred models for OECD industrial energy demand incorporate both a stochastic underlying energy demand trend and asymmetric price responses. This gives estimated long-run income elasticities in the range of 0.34 to 0.96; estimated long-run price-maximum elasticities in the range of − 0.06 to − 1.22; estimated long-run price-recovery elasticities in the range of 0.00 to − 0.27; and estimated long-run price-cut elasticities in the range of 0.00 to − 0.18. Furthermore, the analysis suggests that when modelling industrial energy demand there is a place for

    Full Text Available In the last decades, the Brazilian government has put many public policies in place in order to create a favourable environment to promote energy efficiency and clean energy. In this paper we discuss the use of research and development financing support by the clean energy industry in Brazil. To do so, we carried out an empirical research analysing secondary data from legislation, literature case studies, and public and industry reports in order to determine if the companies of the clean energy industry have public financial support to research and development. Our ongoing research shows that, despite incentives to stimulate the dissemination of clean energy, the participation of some of the clean energy is very small (especially solar. We believe that the contributions of this study will assist policy makers, and the whole industry, to improve clean energy research and development investments in Brazil.

    In consequence of the national industrial development, it is necessary to supply a lot of energy. This paper presented a discussion about the option of supplying nuclear processed heat as alternative energy sources for industry especially in Java island. The electrical energy requirement can be estimated rising. The stock and the requirement of energy in Indonesia is unbalance. If the oil production rate is constant, such as that of today, it can be estimated that the oil stock would be over in 20 years. The country is trying to difertify its source of energy and reduce its dependence on oil. High Temperature Reactor (HTR) produces electric and also heat at various temperature in the form of steam and gas. Heat processes from a high temperature reactor, could be used in industry for supplying heat for coal hidroforming, gasification of coal, metal annealing, petrochemical hydrogenation, distillation, purification of petrochemicals, evaporation, water heat, etc. (author). 8 refs, 1 fig., 5 tabs

    2007-01-01

    'The Use of Nuclear Power for Peaceful Purposes' is a key topic in energy policy which produces a split of opinions in Germany, and which the policy of the Grand Coalition seeks to bypass. The Federation of German Industries (BDI) wants to achieve a sensible way of handling this source of energy because, after all, we are facing the challenge of having to secure economic development and prosperity and, at the same time, reduce global CO 2 emissions. If this is to be achieved, industry and politics together must build a bridge into a future with less CO 2 . That bridge would be supported on 4 pillars: - a global strategy of CO 2 reduction, - energy efficiency, - a broad energy mix, - energy research and development. In these efforts, industry and the BDI consider nuclear power an indispensable part of a viable climate and energy policy. Next to lignite, nuclear power offers electricity generation at the lowest cost, and promotes climate protection through CO 2 -free generation. As far as energy efficiency and a broad energy mix are concerned, the potentials for technical development play an important role. This is an area in which German industry can develop future markets for itself by being a leader in technology. Energy research should advance the development of existing technologies and open up new options. In this way, energy research contributes to high technologies in Germany. For nuclear power, it must be ensured that German scientists are able to participate in promising developments of new reactors in the same way in which this is the case in the development and construction of ITER, the international fusion reactor, in France.

    Highlights: • Decision-making process of the industry and the environment are evaluated in a game theoretic approach. • Industry and environment are considered as two players to find optimal strategies in governing energy policy. • Industry plays its renewable energy usage strategy. • Environment prefers to execute its protection reflex strategy for survivability and sustainability. • The industry’s insistence on the use of fossil fuels will forward strategy for the environment of uncertainty. - Abstract: Intensive energy consuming industrial sectors are the most important actors on global climate change which natural habitat and the environment faced. In this study, by the scope of energy management, decision-making process of the industry and the environment are evaluated in a game theoretic approach. Industry and environment are considered as two players which have conflicting objectives and try to find optimal strategies in governing energy policy. According to concept of study, while industry tries to maintain the sustainability of production with the strategies of fossil fuel, renewable energies, energy recovery and nuclear energy usage, environment exhibits reactive approach to ensure its sustainability. In the flow of study, players’ strategies are analyzed by using Multi-Criteria Decision Making (MCDM) methods and by calculating performance efficiency values of strategies, game payoff matrix is obtained. Finally, optimal strategies are found for both industry and environment in orienting their energy policy and results are evaluated. According to results of the payoff matrix, the equilibrium point is the cell (2, 1) with the values of 0.5324 and 0.5619. This implies that the environment develops protective reflexes for sustainable nature in case of using renewable energy in industry

    Past energy-consumption trends and future energy-conservation opportunities are investigated for the nation's iron and steel industry. It is estimated that, in 1980, the industry directly consumed approximately 2.46 x 10/sup 15/ Btu of energy (roughly 3% of total US energy consumption) to produce 111 million tons of raw steel and to ship 84 million tons of steel products. Direct plus indirect consumption is estimated to be about 3.1 x 10/sup 15/ Btu. Of the set of conservation technologies identified, most are judged to be ready for commercialization if and when the industry's capital formation and profitability problems are solved and the gradual predicted increase in energy prices reduces the payback periods to acceptable levels.

    Full Text Available Wave and current energy can be harnessed in the East China Sea and South China Sea; however, both areas are subject to high frequencies of typhoon events. To improve the safety of the ocean energy conversion device, a Floating Ocean Energy Conversion Device (FOECD with a single mooring system is proposed, which can be towed to avoid severe ocean conditions or for regular maintenance. In this paper, the structure of the FOECD is introduced, and it includes a catamaran platform, an oscillating buoy part, a current turbine blade, hydraulic energy storage and an electrical generation part. The numerical study models the large catamaran platform as a single, large buoy, while the four floating buoys were modeled simply as small buoys. Theoretical models on wave energy power capture and efficiency were established. To improve the suitability of the buoy for use in the FOECD and its power harvesting capability, a numerical simulation of the four buoy geometries was undertaken. The shape profiles examined in this paper are cylindrical, turbinate (V-shaped and U-shaped cone with cylinder, and combined cylinder-hemisphere buoys. Simulation results reveal that the suitability of a turbinate buoy is the best of the four types. Further simulation models were carried out by adjusting the tip radius of the turbinate buoy. Three performance criteria including suitability, power harvesting capability and energy capture efficiency were analyzed. It reveals that the turbinate buoy has almost the same power harvesting capabilities and energy capture efficiency, while its suitability is far better than that of a cylindrical buoy.

    2013-04-02

    A combination of declining costs and policy measures motivated by greenhouse gas (GHG) emissions reduction and energy security have driven rapid growth in the global installed capacity of solar photovoltaics (PV). This paper develops a number of unique data sets, namely the following: calculation of distribution of global capacity factor for PV deployment; meta-analysis of energy consumption in PV system manufacture and deployment; and documentation of reduction in energetic costs of PV system production. These data are used as input into a new net energy analysis of the global PV industry, as opposed to device level analysis. In addition, the paper introduces a new concept: a model tracking energetic costs of manufacturing and installing PV systems, including balance of system (BOS) components. The model is used to forecast electrical energy requirements to scale up the PV industry and determine the electricity balance of the global PV industry to 2020. Results suggest that the industry was a net consumer of electricity as recently as 2010. However, there is a >50% that in 2012 the PV industry is a net electricity provider and will "pay back" the electrical energy required for its early growth before 2020. Further reducing energetic costs of PV deployment will enable more rapid growth of the PV industry. There is also great potential to increase the capacity factor of PV deployment. These conclusions have a number of implications for R&D and deployment, including the following: monitoring of the energy embodied within PV systems; designing more efficient and durable systems; and deploying PV systems in locations that will achieve high capacity factors.

    Highlights: • A long-term equilibrium relationship of energy demand in China’s petroleum refining industry is established. • The sectoral energy conservation potential is evaluated by using scenarios analysis. • Energy prices, enterprise scale, R and D investment and ownership structure affect electricity intensity. • Future policy for energy conservation in China’s petroleum refining industry is suggested. - Abstract: China is currently the second largest petroleum refining country in the world due to rapid growth in recent years. Because the petroleum refining industry is energy-intensive, the rapid growth in petroleum refining and development caused massive energy consumption. China’s urbanization process will guarantee sustained growth of the industry for a long time. Therefore, it is necessary to study the energy conservation potential of the petroleum industry. This paper estimates the energy conservation potential of the industry by applying a cointegration model to investigate the long-run equilibrium relationship between energy consumption and some factors such as energy price, enterprise scale, R and D investment and ownership structure. The results show that R and D investment has the greatest reduction impact on energy intensity, and the growth of market participants (i.e. the decline of the share of state-owned companies) can improve energy efficiency of this industry. Under the advanced energy-saving scenario, the accumulated energy conservation potential will reach 230.18 million tons of coal equivalent (tce). Finally, we provide some targeted policy recommendations for industrial energy conservation

    Tertiary industry has been developed in recent years. And it is very important to find the factors influenced the energy-related carbon emissions in tertiary industry. A decomposition model of energy-related carbon emissions for China is set up by adopting logarithmic mean weight Divisia method based on the identity of carbon emissions. The model is adopted to analyze the influence of energy structure, energy efficiency, tertiary industry structure and economic output to energy-related carbon emissions in China from 2000 to 2009. Results show that the contribution rate of economic output and energy structure to energy-related carbon emissions increases year by year. Either is the contribution rate of energy efficiency or the tertiary industry restraining to energy-related carbon emissions. However, the restrain effect is weakening.

    2005-01-01

    The JAERI FEL has first discovered the new FEL lasing of 255fs ultra fast pulse, 6-9% high efficiency, 1GW high peak power, a few kilowatts average power, and wide tunability of medium and far infrared wavelength regions at the same time. Using the new lasing and energy-recovery linac technology, we could extend a more powerful and more efficient free-electron laser (FEL) than 10kW and 25%, respectively, for nuclear energy industries, and others. In order to realize such a tunable, highly-efficient, high average power, high peak power and ultra-short pulse FEL, we need the efficient and powerful FEL driven by the JAERI compact, stand alone and zero boil-off super-conducting RF linac with an energy-recovery geometry. Our discussions on the FEL will cover the application of non-thermal peeling, cutting, and drilling to prevent cold-worked stress-corrosion cracking failures in nuclear energy and other heavy industries.

    2007-01-01

    Hybrid photovoltaic/thermal (PV/T) systems consist of PV modules and heat extraction units mounted together. These systems can simultaneously provide electrical and thermal energy, thus achieving a higher energy conversion rate of the absorbed solar radiation than plain photovoltaics. Industries show high demand of energy for both heat and electricity and the hybrid PV/T systems could be used in order to meet this requirement. In this paper the application aspects in the industry of PV/T systems with water heat extraction is presented. The systems are analyzed with TRNSYS program for three locations Nicosia, Athens and Madison that are located at different latitudes. The system comprises 300 m 2 of hybrid PV/T collectors producing both electricity and thermal energy and a 10 m 3 water storage tank. The work includes the study of an industrial process heat system operated at two load supply temperatures of 60 deg. C and 80 deg. C. The results show that the electrical production of the system, employing polycrystalline solar cells, is more than the amorphous ones but the solar thermal contribution is slightly lower. A non-hybrid PV system produces about 25% more electrical energy but the present system covers also, depending on the location, a large percentage of the thermal energy requirement of the industry considered. The economic viability of the systems is proven, as positive life cycle savings are obtained in the case of hybrid systems and the savings are increased for higher load temperature applications. Additionally, although amorphous silicon panels are much less efficient than the polycrystalline ones, better economic figures are obtained due to their lower initial cost, i.e., they have better cost/benefit ratio

    The structure of the industrial sector is a factor of major importance in analyzing the evolution of energy intensity or in setting-up realistic development scenarios. A positive influence on the energy intensity value is expected for Romania from the process of restructuring the industry sector towards low energy consumption products. In order to reach this target though, suitable end comprehensive strategies have to become operational without delay, promoting energy efficiency and modern technologies at a nation-wide scale. The benefits of such strategies extend from improvement of the security of supply through environmental protection and reduction of unemployment. (Author)

    The focus of this ongoing work is the utilisation of general non hazardous industrial and commercial waste as an energy or fuel source. Whereas much of the existing experience in energy from waste (EFW) is related to municipal solid wastes (MSW), there is very little direct experience with these other waste streams and the shortage of reliable information in this field is notoriously lacking. It is important to have a good understanding of the private waste contracting industry (pwci) in order to establish the conditions under which energy from waste technologies may play an economically and technically feasible role within that industry's development. The Non Fossil Fuel Obligation (NFFO) has encouraged entrepreneurial interest through premium payments for electricity generated from renewable sources. (author)

    The Ocean Thermal Energy Conversion (OTEC) Life Cycle Cost Assessment (OLCCA) is a study performed by members of the Lockheed Martin (LM) OTEC Team under funding from the Department of Energy (DOE), Award No. DE-EE0002663, dated 01/01/2010. OLCCA objectives are to estimate procurement, operations and maintenance, and overhaul costs for two types of OTEC plants: -Plants moored to the sea floor where the electricity produced by the OTEC plant is directly connected to the grid ashore via a marine power cable (Grid Connected OTEC plants) -Open-ocean grazing OTEC plant-ships producing an energy carrier that is transported to designated ports (Energy Carrier OTEC plants) Costs are developed using the concept of levelized cost of energy established by DOE for use in comparing electricity costs from various generating systems. One area of system costs that had not been developed in detail prior to this analysis was the operations and sustainment (O&S) cost for both types of OTEC plants. Procurement costs, generally referred to as capital expense and O&S costs (operations and maintenance (O&M) costs plus overhaul and replacement costs), are assessed over the 30 year operational life of the plants and an annual annuity calculated to achieve a levelized cost (constant across entire plant life). Dividing this levelized cost by the average annual energy production results in a levelized cost of electricity, or LCOE, for the OTEC plants. Technical and production efficiency enhancements that could result in a lower value of the OTEC LCOE were also explored. The thermal OTEC resource for Oahu, Hawaii and projected build out plan were developed. The estimate of the OTEC resource and LCOE values for the planned OTEC systems enable this information to be displayed as energy supplied versus levelized cost of the supplied energy; this curve is referred to as an Energy Supply Curve. The Oahu Energy Supply Curve represents initial OTEC deployment starting in 2018 and demonstrates the

    Full Text Available Industrial structure is one of the main factors that determine energy consumption. Based on China’s energy consumption in 2015 and the goals in 13th Five-Year Plan for Economic and Social Development of the People’s Republic of China (The 13th Five-Year Plan, this paper established an input–output fuzzy multi-objective optimization model to estimate the potential impacts of China’s industrial structure on energy consumption in 2015. Results showed that adjustments to industrial structure could save energy by 19% (1129.17 million ton standard coal equivalent (Mtce. Second, China’s equipment manufacturing industry has a large potential to save energy. Third, the development of several high energy intensive and high carbon intensive sectors needs to be strictly controlled, including Sector 25 (electricity, heat production, and supply industry, Sector 11 (manufacture of paper and stationery, printing, and Sector 14 (non-metallic mineral products industry. Fourth, the territory industry in China has a great potential for energy saving, while its internal structure still needs to be upgraded. Finally, we provide policy suggestions that may be adopted to reduce energy consumption by adjusting China’s industrial structure.

  1. Addressing industrial competitiveness concerns in the 2030 EU Climate and Energy Package

    Sartor, Oliver; Colombier, Michel; Spencer, Thomas

    2014-01-01

    In the current sombre economic context, the issue of industrial competitiveness has become highly salient. Europe's industrial challenges need to be understood to be addressed. Europe like other major economies has gone through the resource intensive phase of building its capital stock. At Europe's level of development, high incomes tend to be spent on high value added services and manufactures. These factors mean that Europe's industry has been undergoing a long-term transition since the early 70's. In addition, European industry has been hit by a deep cyclical downturn as a result of the crisis. This long-term structural trend and current conjectural situation have nothing to do with energy policy. However, it would be wrong to suggest that energy prices do not play a role for certain industries. For a few highly energy and trade intensive industries, energy prices are a significant factor of comparative advantage. These industries will need protection in the 2030 climate and energy package, especially if a meaningful CO 2 price is to emerge. The current mechanisms to address competitiveness involve a number of drawbacks, notably the distortions and windfall profits that they entail due to variations of production levels from the historical reference used for free allocation. They also do not effectively address electricity intensive industries. Finding a solution to these issues is important for negotiating a meaningful future framework. Options that could be considered include moving to output based allocation for energy intensive, trade exposed industries, or considering temporary opt-outs for these industries. Given the potential risks around temporary opt-outs, output based allocation could be a way forward, combined with a much tighter focus on the energy intensive, trade exposed industries and a harmonized system for dealing with electricity intensive industries.

    Korean energy industry is experiencing a radical paradigm shift. Vertically integrated monopoly is being dismantled while state-owned energy companies are privatized. The industry is in transition from extensive government control to more flexible and market-oriented operation. Along with the task of successfully implementing these structural changes, Korea is now faced with challenges of addressing energy security with the decentralized supply system. This paper discusses ongoing efforts to transform electric power and natural gas industries in Korea, and then explores possible schemes for regional energy cooperation that will enhance efficiency and supply security

    The technological expertise within the Canadian service industry has turned the industry into a multi-billion dollar business in less than two decades. The Petroleum Services Association of Canada (PSAC) was initially formed in 1981 to combat the government's National Energy Program (NEP) which, although designed to protect Canadian resources and companies against foreign incursions, ended up hurting just about everyone in the industry. PSAC's current mandate is to represent companies involved in the oil and gas service, supply and manufacturing industry when dealing with federal and provincial governments, regulatory agencies and energy producers. PSAC has helped develop a set of safety standards for Canadian well testers. PSAC also created a spin-off organization called Petro-Trade which is geared to help the Canadian service industry sell its experience and expertise to the international marketplace. A similar organization that serves the Canadian petroleum sector is the Newfoundland Ocean Industries Association (NOIA). It was established in the early days of East Coast offshore exploration to help service and producing companies have a voice in the region's energy industry. The NOIA focuses on the energy industry in Newfoundland, the Maritime provinces, the rest of Canada, and other countries such as the United States and Norway. 2 figs

  5. Some new conceptions in the approach to harnessing tidal energy

    Science.gov (United States)

    Gorlov, A. M.

    A method of converting ocean tide energy into compressed air energy for subsequent conversion to electrical and other forms of industrial energy is presented. The tidal energy is converted to compressed air energy by means of specialized chambers which are put on the ocean bed. Ocean water from the dammed region passes through the chamber where it works as a natural piston compressing air in the upper part of the closure. The compressed air can be expanded through high speed compact gas turbines or any type of reciprocating engine. The flexible reinforced plastic barrier should be substantially cheaper than a conventional rigid dam and can be designed so that by means of special floats it becomes a self-supported and self-regulated weightless structural system which can dam a large shallow space of ocean without having to be connected to special bays.

    This study evaluates the energy efficiency trends of five energy-intensive industries in 23 European Union (EU) countries over the period 2000–2009. In particular, the performance of the construction, electricity, manufacturing, mining and quarrying, and transport sectors is examined. The analysis is based on Data Envelopment Analysis (DEA) combined with the Malmquist Productivity Index (MPI), which allows for distinctions between efficiency and technology changes over time. At the second stage of the analysis, cross-classified multilevel modelling is applied to analyse the main drivers behind efficiency performance using a number of sector and country characteristics. Based on DEA results, an overall improvement in efficiency is observed in all sectors over the period. The decomposition of the MPI indicates that technology change is primarily responsible for the improvements achieved in most sectors. The results obtained by the cross-classified model show, among other things, that the high electricity prices, energy taxes, and market share of the largest generator in the electricity market have a negative effect on industrial energy efficiency. - Highlights: • Analysis of energy efficiency and trends of industrial sectors in EU. • Combination of non-parametric frontier models and multilevel explanatory analysis. • Examination of the drivers of energy efficiency. • Industrial energy efficiency performance is mainly driven by technological improvement.

    Industrial boiler is one of the most energy-consuming equipments in china, the annual consumption of energy accounts for about one-third of the national energy consumption. Industrial boilers in service at present have several severe problems such as small capacity, low efficiency, high energy consumption and causing severe pollution on environment. In recent years, our country in the big scope, long time serious fog weather, with coal-fired industrial boilers is closely related to the regional characteristics of high strength and low emissions [1]. The energy-efficient and emission-reducing of industry boiler is of great significance to improve China’s energy usage efficiency and environmental protection. Difference in thermal equilibrium theory is widely used in boiler design, exergy analysis method is established on the basis of the first law and second law of thermodynamics, by studying the cycle of the effect of energy conversion and utilization, to analyze its influencing factors, to reveal the exergy loss of location, distribution and size, find out the weak links, and a method of mining system of the boiler energy saving potential. Exergy analysis method is used for layer combustion boiler efficiency and pollutant emission characteristics analysis and evaluation, and can more objectively and accurately the energy conserving potential of the mining system of the boiler, find out the weak link of energy consumption, and improve equipment performance to improve the industrial boiler environmental friendliness.

  14. Energy Efficiency Improvement and Cost Saving Oportunities for the Concrete Industry

    The U.S. concrete industry is the main consumer of U.S.-produced cement. The manufacturing of ready mixed concrete accounts for more than 75% of the U.S. concrete production following the manufacturing of precast concrete and masonry units. The most significant expenditure is the cost of materials accounting for more than 50% of total concrete production costs - cement only accounts for nearly 24%. In 2009, energy costs of the U.S. concrete industry were over $610 million. Hence, energy efficiency improvements along with efficient use of materials without negatively affecting product quality and yield, especially in times of increased fuel and material costs, can significantly reduce production costs and increase competitiveness. The Energy Guide starts with an overview of the U.S. concrete industry’s structure and energy use, a description of the various manufacturing processes, and identification of the major energy consuming areas in the different industry segments. This is followed by a description of general and process related energy- and cost-efficiency measures applicable to the concrete industry. Specific energy and cost savings and a typical payback period are included based on literature and case studies, when available. The Energy Guide intends to provide information on cost reduction opportunities to energy and plant managers in the U.S. concrete industry. Every cost saving opportunity should be assessed carefully prior to implementation in individual plants, as the economics and the potential energy and material savings may differ.

    As petroleum-based fuels grow increasingly scarce and costly, nuclear energy may become an important alternative source of industrial energy. Initial applications would most likely include a mix of fossil-fired and nuclear sources of process energy. A means for determining the overall reliability of these mixed systems is a fundamental aspect of demonstrating their feasibility to potential industrial users. Reliability data from nuclear and fossil-fired plants are presented, and several methods of applying these data for calculating the reliability of reasonably complex industrial energy supply systems are given. Reliability estimates made under a number of simplifying assumptions indicate that multiple nuclear units or a combination of nuclear and fossil-fired plants could provide adequate reliability to meet industrial requirements for continuity of service

    In Saudi Arabia, industrial fuel prices are administered below international prices and firms make decisions based on low energy prices, increasing domestic energy demand. This analysis explores alternative policies designed to induce a transition to a more efficient energy system by immediately deregulating industrial fuel prices, gradually deregulating fuel prices, and introducing investment credits or feed-in tariffs. It uses a dynamic multi-sector, mixed-complementarity model. Continuing existing policies results in a power system still fueled completely by hydrocarbons. The alternative policies result in a transition to a more efficient energy system where nuclear and renewable technologies become cost-effective and produce 70% of the electricity in 2032. Introducing the alternative policies can reduce the consumption of oil and natural gas by up to 2 million barrels of oil equivalent per day in 2032, with cumulative savings between 6.3 and 9.6 billion barrels of oil equivalent. The energy system sees a net economic gain up to half a trillion 2014 USD from increased oil exports, even with investments in nuclear and renewables. The results are robust to alternative assumptions regarding the value of oil saved and the growth in end-use energy demand. - Highlights: • We model the effect of reforming fuel prices to industrial sectors in Saudi Arabia. • Alternate policies can lower oil and gas use by up to two million boe/day in 2032. • Large economic gains could be achieved by reforming industrial fuel prices. • Some pricing policies manage transition without compromising the economic gain. • Saudi Arabia can maintain large crude oil export capacity by 2032.

    1994-01-01

    During the decade of the 1980s the California biomass energy industry grew from a few isolated facilities located mostly at pulp mills into the largest biomass energy industry in the world. Currently, more than fifty biomass powered electricity generating facilities provide the state with some 850 Megawatts (MW) of generating capacity, most of it interconnected to the state's electric utility systems. Each year, more than ten million tons of wood and agricultural wastes in the state are converted into fuel, rather than being disposed of using conventional, environmentally costly methods like open burning and landfill burial. As the 1980s began, the California biomass energy industry was in a nascent state. Optimism was blooming within the wood-products and agricultural sectors of California, who foresaw an opportunity to turn costly wastes into profits. At the same time, the independent energy industry itself was being launched. Interest in biomass energy development was spreading to the engineering and construction industries and the financial community as well. A great variety of firms and individuals were engaged in the development of biomass power plants and biomass fuel sources. The second half of the 1980s saw the fruits of the developmental activity that began in the first half of the decade. Biomass energy facilities were entering construction and coming on-line in increasing numbers, and the demand for biomass fuels was increasing in step. As the decade was coming to an end, biomass fuel supplies were hard put to meet the demand, yet a huge number of new facilities entered operation in 1990. This extreme growth spurt of new generating capacity caused a fuel crisis and a shake-out in the industry just as it was entering full-scale operation. The Crisis of Success had been reached. More recently an equilibrium has been achieved in which fuel prices are at levels that produce adequate supplies, while allowing profitable operations at the power plants

    Industry consumes about 40 percent of the total primary energy used in the United States. Natural gas and oil, the major industrial fuels, are becoming scarce and expensive; therefore, there is a critical national need to develop alternative sources of industrial energy based on the more plentiful domestic fuels--coal and nuclear. This report gives the results of a comparative assessment of nuclear- and coal-based industrial energy systems which includes technical, environmental, economic, and resource aspects of industrial energy supply. The nuclear options examined were large commercial nuclear power plants (light-water reactors or high-temperature gas-cooled reactors) and a small [approximately 300-MW(t)] special-purpose pressurized-water reactor for industrial applications. Coal-based systems selected for study were those that appear capable of meeting environmental standards, especially with respect to sulfur dioxide; these are (1) conventional firing using either low- or high-sulfur coal with stack-gas scrubbing equipment, (2) fluidized-bed combustion using high-sulfur coal, (3) low- and intermediate-Btu gas, (4) high-Btu pipeline-quality gas, (5) solvent-refined coal, (6) liquid boiler fuels, and (7) methanol from coal. Results of the study indicated that both nuclear and coal fuel can alleviate the industrial energy deficit resulting from the decline in availability of natural gas and oil. However, because of its broader range of application and relative ease of implementation, coal is expected to be the more important substitute industrial fuel over the next 15 years. In the longer term, nuclear fuels could assume a major role for supplying industrial steam. (U.S.)

    The lack of a system for benchmarking industrial plant energy efficiency represents a major obstacle to improving efficiency. While estimates are sometimes available for specific technologies, the efficiency of one plant versus another could only be captured by benchmarking the energy efficiency of the whole plant and not by looking at its components. This paper presents an approach used by ENERGY STAR to implement manufacturing plant energy benchmarking for the cement industry. Using plant-level data and statistical analysis, we control for factors that influence energy use that are not efficiency, per se. What remains is an estimate of the distribution of energy use that is not accounted for by these factors, i.e., intra-plant energy efficiency. By comparing two separate analyses conducted at different points in time, we can see how this distribution has changed. While aggregate data can be used to estimate an average rate of improvement in terms of total industry energy use and production, such an estimate would be misleading as it may give the impression that all plants have made the same improvements. The picture that emerges from our plant-level statistical analysis is more subtle; the most energy-intensive plants have closed or been completely replaced and poor performing plants have made efficiency gains, reducing the gap between themselves and the top performers, whom have changed only slightly. Our estimate is a 13 % change in total source energy, equivalent to an annual reduction of 5.4 billion/kg of energy-related carbon dioxide emissions.

    Industrial districts show characteristics that can be exploited by developing plant solutions studied for their special configuration and not simply extended from single unit models. In the paper a waste-to-energy plant for the chair industrial district in Friuli Venezia Giulia (North Eastern Italy) is described. It has been designed directly involving the University of Udine and can be considered an example of how technology innovation can be promoted by universities, especially in the case of small firms which have limited R and D resources. It is shown how industrial refuse becomes a chance of competitive advantage for the whole district due to its energy recovery in a plant unique for the type of waste processed. Input, combustion, energy recovery and cleaning sections are described in details, underlining innovative approaches and solutions [it

    Energy conservation and environmental protection is the basic policy of China, and is an important part of ecological civilization construction. The industrial boilers in China are featured by large quantity, wide distribution, high energy consumption and heavy environmental pollution, which are key problems faced by energy conservation and environmental protection in China. Meanwhile, industrial boilers are important equipment for national economy and people’s daily life, and energy conservation gets through all segments from type selection, purchase, installation and acceptance to fuel management, operation, maintenance and service. China began to implement such national mandatory standards and regulations for industrial boiler as GB24500-2009 The Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades of Industrial Boilers and TSG G002-2010 Supervision Regulation on Energy-Saving Technology for Boilers since 2009, which obviously promote the development of energy conservation of industrial boilers, but there are also some problems with the rapid development of technologies for energy conservation of industrial boilers. In this paper, the implementation of energy efficiency standards for industrial boilers in China and the significance are analyzed based on survey data, and some suggestions are proposed for the energy efficiency standards for industrial boilers.

    2016-01-01

    The Compressed Air Sector accounts for a mean 10% worldwide electricity consumption, which ensures about its importance, when energy saving and CO_2 emissions reduction are in question. Since the compressors alone account for 15% overall industry electricity consumption, it appears vital to pay attention to machine performances. The paper presents an overview of present compressor technology and focuses on saving directions for screw and sliding vanes machines, according to data provided by the Compressed Air and Gas Institute and PNEUROP. Data were processed to obtain consistency with fixed reference pressures and organized as a function of main operating parameters. Each sub-term, contributing to the overall efficiency (adiabatic, volumetric, mechanical, electric, organic), was considered separately: the analysis showed that the thermodynamic improvement during compression achievable by splitting the compression in two stages, with a lower compression ratio, opens the way to significantly reduce the energy specific consumption. - Highlights: • Compressors technology overview in industrial compressed air systems. • Market compressors efficiency baseline definition. • Energy breakdown and evaluation of main efficiency terms. • Assessment of air cooling-related energy saving potential. • Energy specific consumption reduction through dual stage compression.

    In the last few years, rare earth materials (REM) prices have experienced a strong increase due to geopolitical and sustainability issues. Financial markets could already have factored in concerns about shortages of REM supplies into clean energy companies’ valuations. We use a multifactor market model for the period January 2006 to September 2012 to analyze the impact of REM price trends – specifically dysprosium and neodymium – on six clean energy indices (NYSE–BNEF) tracking the world's most important companies in the clean energy sector. The results show that during period of price increase, there is a negative relationships between REM price changes and the stock market performance of some clean energy indices. The European clean energy index is also negatively affected, and this effect could be relevant to policy makers, considering that Europe is implementing some relevant policy actions to support the development of the clean energy industry. - Highlights: • Clean energy is an industry with a double-digit growth market rate in the last years. • Rare earth materials are a key component in the development process of this industry. • Recently REMs’ prices have skyrocketed and the clean energy industry is in turmoil. • We analyze the effect of REMs price on the stock market performances of clean industry. • We find negative relation between REMs price increase and stock market performances

    Abstracts: The Korean government adopted “green growth” in 2008 as an environmentally friendly growth strategy. The energy efficiency of Korea, however, is still relatively low due to the large portion of energy intensive industry (EII) in its manufacturing sector. To improve energy efficiency in Korea, from an EII perspective a new approach has to be taken because restructuring entire industries would take too much time and be too costly. This study aims to emphasize the importance of innovation and analyze the effects of R&D on product and process innovations in EII in Korea. The Probit model is adopted to estimate the effects of eight determinants in the Korea Innovation Survey 2008 data. The results of this study demonstrate that one of the most important determinants, the R&D personnel ratio, has a strong positive effect on both product and process innovation, while another determinant, R&D intensity, only has a strong and positive effect on process innovation in EII. Because of the resulting innovation, energy policies should be enacted to enhance energy efficiency. Thus, the Korean government should keep providing incentives for firms in EII to invest more financial and human resources in their R&D activities. -- Highlights: •We analyze determinants on two innovations in energy intensive industry (EII). •The R&D personnel ratio is effective in product innovation in EII. •Both R&D intensity and R&D personnel are effective in process innovation in EII. •In less EII, R&D variables have positive effects on product and process innovations. •The Korean government should strongly support R&D to improve energy efficiency

    In this paper, Advanced Process Control strategies aimed at energy efficiency achievement and improvement in cement and steel industry are proposed. A flexible and smart control structure constituted by several functional modules and blocks has been developed. The designed control strategy is based on Model Predictive Control techniques, formulated on linear models. Two industrial control solutions have been developed, oriented to energy efficiency and process control improvement in cement industry clinker rotary kilns (clinker production phase) and in steel industry billets reheating furnaces. Tailored customization procedures for the design of ad hoc control systems have been executed, based on the specific needs and specifications of the analysed processes. The installation of the developed controllers on cement and steel plants produced significant benefits in terms of process control which resulted in working closer to the imposed operating limits. With respect to the previous control systems, based on local controllers and/or operators manual conduction, more profitable configurations of the crucial process variables have been provided.

    United States energy policies aim at cutting down dependence on foreign oil in two ways: by energy conservation and by finding new domestic supplies. The study investigates how the first goal can be achieved in the industrial sector (manufacturing) of the economy, which accounts for about 40% (about 7.3 million barrels per day) of the total energy consumption in the US. It is noted that industry is able to conserve as much as 25 to 30% of its energy consumption by adopting simple conservation measures and energy-efficient technologies. These technologies can be implemented without major alterations of the original equipment. The schools of thought on innovative processes are discussed; these will serve as the conceptual and methodological base of the project. (MCW)

    Energy consumption data in the food products industry were collected by a postal survey and by factory energy surveys. Average levels of energy consumption were evaluated for various product types, sugar refining was found to require 4.0 MJ/kg, fat and oil processing 8.5 MJ/kg, pasta product manufacture 4.3 MJ/kg, instant coffee production 48 MJ/kg, roasting of coffee beans 2.2 MJ/kg, vinegar production 3.3 MJ/litre, compressed yeast production 5.4 MJ/kg, sandwich spread preparation 5.3 MJ/kg, drying of products with initial moisture contents below 30% 8.2 MJ/kg, drying of products with initial moisture contents of 70 to 90% 39 MJ/kg and dry mixing of powders 0.46 MJ/kg. Data were also obtained for a variety of other minor products. For any particular product, differences in energy use that occurred between factories could largely be explained by differences in types of factory services and processes. Some data were available for equivalent US industries and in general, the New Zealand industy uses either a similar amount of or less energy than these United States industries. Possible areas for energy conservation in the industry are discussed.

    Full Text Available Energy consumption during waste water treatment is a very important factor affecting food industry plants. Apart from highly efficient treatment of dairy and meat sewage, a low energy consumption is required in order to lower its costs. During the research period parameters of raw and treated sewage were tested (BOD, COD, N-total, P-total. Also, the energy consumption from selected processes as well as total consumption were measured. Indicators of energy consumption per m3 and removed load were calculated. It was found that biological treatment and aeration played the main role in energy consumption in both objects. It was respectively 40 and 47% for Bielmlek and JBB plants. The second biggest energy consuming stage of treatment in both objects was sludge processing. Energy required to process excessive sludge equaled 30% of the total energy usage in both plants. Energy consumption factors related to hydraulic flow gave results in the range from 2,05 to 3,3 kWhm-3 and from 2,72 to 3,23 kWhm-3 for Bielmlek and JBB plants respectively. The research will be continued in order to optimize energy consumption while retaining high efficiency treatment in food industry WWTPs. Finally a mathematical model will be prepared for optimizing energy consumption in food industry WWTPs.

    An in-depth report on energy consumption in the New Zealand dairy industry for 1974--75 shows that a reduction in fuel consumption per unit of production has occurred when compared with two previous surveys (1954--55 and 1964--65). The increase in thermal efficiency of dairy processing was due mainly to the use of hot water heating systems in milk-treatment stations, the increased capacity of butter and cheese factories, increased thermal efficiency in skim milk drying and casein manufacture, increased efficiency in boiler plants, and higher drying air temperature achieved with the use of indirect oil- and gas-fired air heaters and liquid-phase air heating systems. Total energy consumed by the industry by type is tabulated. Recommendations to the industry following the survey are listed. (MCW)

    The U.S. dairy processing industry—defined in this Energy Guide as facilities engaged in the conversion of raw milk to consumable dairy products—consumes around $1.5 billion worth of purchased fuels and electricity per year. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. dairy processing industry to reduce energy consumption and greenhouse gas emissions in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, facility, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the U.S. dairy processing industry is provided along with a description of the major process technologies used within the industry. Next, a wide variety of energy efficiency measures applicable to dairy processing plants are described. Many measure descriptions include expected savings in energy and energy-related costs, based on case study data from real-world applications in dairy processing facilities and related industries worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. Given the importance of water in dairy processing, a summary of basic, proven measures for improving water efficiency are also provided. The information in this Energy Guide is intended to help energy and plant managers in the U.S. dairy processing industry reduce energy and water consumption in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of all measures—as well as on their applicability to different production practices—is needed to assess their cost effectiveness at individual plants.

  4. Application of energy conservation technologies in Indian industries

    The quadrupling of oil prices in 1973 signaled the beginning of a crises period for the oil importing countries. It hampered the economic growth of developed and developing countries alike. The pace of industrialization slowed down, recession set in and the oil importing developing nations found their balance of payment situation steadily going worse. The second increase of oil prices in 1979 further compounded the problems. It did seem that the problem of economic growth and increasing debt burden was intractable as far as developing nations were concerned. Behind this turmoil were the faint stirrings of alternative actions that sought to wean the world from its oil and fossil fuel dominated economies. These alternatives ranged from harnessing renewable energy sources, such as solar, wind and biomass to implementing end-use energy efficiency strategies. A major lesson of the oil crunch era was that energy efficiency is tangible resource by itself that competes economically with contemporary energy supply options. In addition to this, four major national priorities, viz, economic competitiveness, utilization of scare capital for development, environmental quality and energy security through oil dependence provided an urgent rationale for saving energy. While conservation consciousness has already taken roots in Pakistan industry, it needs to be nurtured and gains need to be consolidated. The need of the hour is to take stock of the situation elsewhere, particularly in similar geographical and socio-economic situations, and plan for an energy efficient tomorrow. This article attempts to delineate the notable developments that have taken place in the application of energy conservation technologies in the Indian industries. These efforts have had a salutary effect on the Indian value added sector which was saddled with old plant and machinery designed in the era of cheap energy. (author)

    Since Taiwan lacks sufficient self-produced energy, increasing energy efficiency and energy savings are essential aspects of Taiwan's energy policy. This work summarizes the energy savings implemented by 303 firms in Taiwan's textile industry from the on-line Energy Declaration System in 2008. It was found that the total implemented energy savings amounted to 46,074 ton of oil equivalent (TOE). The energy saving was equivalent to 94,614 MWh of electricity, 23,686 kl of fuel oil and 4887 ton of fuel coal. It represented a potential reduction of 143,669 ton in carbon dioxide emissions, equivalent to the annual carbon dioxide absorption capacity of a 3848 ha plantation forest. This study summarizes energy-saving measures for energy users and identifies the areas for making energy saving to provide an energy efficiency baseline.

  8. Industrial Energy Management Decision Making for Improved Energy Efficiency—Strategic System Perspectives and Situated Action in Combination

    2015-06-01

    Full Text Available Improved industrial energy efficiency is a cornerstone in climate change mitigation. Research results suggest that there is still major untapped potential for improved industrial energy efficiency. The major model used to explain the discrepancy between optimal level of energy efficiency and the current level is the barrier model, e.g., different barriers to energy efficiency inhibit adoption of cost-effective measures. The measures outlined in research and policy action plans are almost exclusively technology-oriented, but great potential for energy efficiency improvements is also found in operational measures. Both technology and operational measures are combined in successful energy management practices. Most research in the field of energy management is grounded in engineering science, and theoretical models on how energy management in industry is carried out are scarce. One way to further develop and improve energy management, both theoretically as well as practically, is to explore how a socio-technical perspective can contribute to this understanding. In this article we will further elaborate this potential of cross-pollinating these fields. The aim of this paper is to relate energy management to two theoretical models, situated action and transaction analysis. We conclude that the current model for energy management systems, the input-output model, is insufficient for understanding in-house industrial energy management practices. By the incorporation of situated action and transaction analysis to the currently used input-output model, an enhanced understanding of the complexity of energy management is gained. It is not possible to find a single energy management solution suitable for any industrial company, but rather the idea is to find a reflexive model that can be adjusted from time to time. An idea for such a reflexive model would contain the structural elements from energy management models with consideration for decisions being

    1997-01-01

    The iron and steel industry, which accounts for between two and three percent of all energy consumed in this country, is also striving to improve its energy efficiency. The amount of energy required to produce a ton of steel has decreased by more than 40% since 1975. This reduction has been accomplished in part through adoption of more energy-efficient and productive processing steps. However, the capital to invest in new technologies is increasingly limited, especially as the costs of environmental control continue to rise. Other than foreign competition, the biggest challenge facing the industry today is compliance with environmental regulations. The Clean Air Act and the Resource Conservation and Recovery Act have had significant impacts on the industry. Since 1970, the industry has invested approximately $6 billion in pollution control systems. The industry spent approximately $230 million in both 1993 and 1994 on capital expenditures for pollution abatement. In a typical year, 15% of the industry's capital investments go to environmental projects. The industry faces even more challenges in the future as new, more stringent regulations are enacted. Topics covered here are: market trends and statistics; energy and materials consumption; and an environmental overview

    Assumptions regarding the magnitude and direction ofenergy-related technological change have long beenrecognized as criticaldeterminants of the outputs and policy conclusions derived fromintegrated assessment models. Particularly in the case of developingcountries, however, empirical analysis of technological change has laggedbehind simulation modeling. This paper presents estimates of sectoralproductivity trends and energy-augmenting technological change forseveral energy-intensive industries in India and South Korea, and, forcomparison, the United States. The key findings are substantialheterogeneity among both industries and countries, and a number of casesof declining energy efficiency. The results are subject to certaintechnical qualifications both in regards to the methodology and to thedirect comparison to integrated assessment parameterizations.Nevertheless, they highlight the importance of closer attention to theempirical basis for common modeling assumptions.

    China is currently in the process of industrialization and urbanization, which is the key stage of transition from a low-income country to a middle-income country and requires large amount of energy. The process will not end until 2020, so China's primary energy demand will keep high growth in the mid-term. Although each country is unique considering its particular history and background, all countries are sharing some common rules in energy demand for economic development. Based on the comparison with developed countries, here, we report some rules in the process of industrialization and urbanization as follows: (1) urbanization always goes along with industrialization; (2) the higher economic growth is, the higher energy demand is; (3) economic globalization makes it possible to shorten the time of industrialization, but the shorter the transition phase is, the faster energy demand grows; (4) the change of energy intensity presents as an “inverted U” curve, but whose shape can be changed for different energy policy. The above rules are very important for the Chinese government in framing its energy policy. - Highlights: ► China's energy demand will maintain high growth in mid-term. ► Urbanization always goes along with industrialization. ► Higher economic growth needs more energy. ► The energy intensity presents as an “inverted U” curve.

  12. Impact of energy on industrial growth

    The equation of growth relates the growth of output Q to the growth of the production factors capital K, labor L, and energy flow E. It can be solved in zero order approximation with respect to time, if one assumes that the characteristic properties of the industrial system are not changed by human creativity and that the economy is far from its thermodynamic limits to growth. Then Q must be a unique function of K, L and E. The integral of the equation of growth with the calculated, factor-dependent elasticities of production yields the production function q.e*exp/left brace/a/sub o/(2-(l+e)/k)+a/sub o/c/sub t/(l/e-1)/right brace/, with q, k, l and e being the relative values of Q, K, L, and E; a/sub o/ and c/sub t/ are the two free parameters of the theory. For given factor inputs, the GNP and the output of the industrial sector of West Germany and the output of the sector ''Industries'' of the United States are calculated for the years 1960-78. Deviations of theory from reality are generally less than 5%. The influence of energy prices on factor inputs and growth is discussed.

  13. Annual electricity consumption forecasting by neural network in high energy consuming industrial sectors

    2008-01-01

    This paper presents an artificial neural network (ANN) approach for annual electricity consumption in high energy consumption industrial sectors. Chemicals, basic metals and non-metal minerals industries are defined as high energy consuming industries. It is claimed that, due to high fluctuations of energy consumption in high energy consumption industries, conventional regression models do not forecast energy consumption correctly and precisely. Although ANNs have been typically used to forecast short term consumptions, this paper shows that it is a more precise approach to forecast annual consumption in such industries. Furthermore, the ANN approach based on a supervised multi-layer perceptron (MLP) is used to show it can estimate the annual consumption with less error. Actual data from high energy consuming (intensive) industries in Iran from 1979 to 2003 is used to illustrate the applicability of the ANN approach. This study shows the advantage of the ANN approach through analysis of variance (ANOVA). Furthermore, the ANN forecast is compared with actual data and the conventional regression model through ANOVA to show its superiority. This is the first study to present an algorithm based on the ANN and ANOVA for forecasting long term electricity consumption in high energy consuming industries

    In Slovenia the actual fast growth of greenhouse emissions will require substantial efforts to fulfil the target set in Kyoto. The end-use emissions in the in the industrial sectors represented one third of the total CO 2 emissions in the country in 1996. The cost-effective potential in the sector for CO 2 emission reduction is significant. In the paper, the most important ongoing energy efficiency activities in the industrial sector are presented: information and awareness building, energy advising to larger industrial consumers, energy audition programme, demonstration programme of energy efficiency technologies, financial incentives for energy efficiency investment and the energy efficiency investment fund. A CO 2 tax has been in force since 1997. The results of an evaluation of energy efficiency strategies in industry in the frame of the project 'Integrated resource planning for the energy efficiency in Slovenia' are discussed from the viewpoint of greenhouse gases reduction targets set by Slovenia, and a brief information on the ongoing and expected post Kyoto activities and studies is given. The most important points of the future GHG reduction strategy related to industrial sector in Slovenia will be focused on intensified energy efficiency programme, increased combined heat and power production (CHP), and the effects of incentives through the CO 2 tax.

    The trade-off between risk and rate-of-return in investment evaluations is crucial in assessing the commercial potential of future energy-conservation technologies. The focus of the Industrial Conservation Program at ERDA is to reduce the perceived risks of a given technology to the extent that the private sector will adopt the technology within the normal course of its business operations. These perceived risks may emanate from technical, institutional, or commercial uncertainties, or in many cases they may result merely from a company's or industry's lack of previous experience with a particular technology. Regardless of the source of the risk surrounding a project, the uncertainty it poses to the private sector will serve to inhibit decisions to invest. This study evaluates the treatment of risk in capital investments in certain energy-intensive industries which are the primary targets of ERDA's Industrial Conservation Program. These risks evaluation considerations were placed within a context that includes capital budgeting practices and procedures, organizational considerations, and basic rate-of-return evaluation procedures in the targeted energy-intensive industries (petroleum, chemicals, paper, textiles, cement, food processing, aluminum, steel, glass, and agriculture).

    In 2010, wind energy coverage in Spain increased by 16%, making the country the world's fourth largest producer in a fast-developing industry that is also a source of employment. Occupational skin diseases in this field have received little attention. The present study aims to describe the main characteristics of skin diseases affecting workers in the wind energy industry and the allergens involved. We performed a descriptive, observational study of workers from the wind energy industry with suspected contact dermatitis who were referred to the occupational dermatology clinic of the National School of Occupational Medicine (Escuela Nacional de Medicina del Trabajo) between 2009 and 2011. We took both a clinical history and an occupational history, and patients underwent a physical examination and patch testing with the materials used in their work. We studied 10 workers (8 men, 2 women), with a mean age of 33.7 years. The main finding was dermatitis, which affected the face, eyelids, forearms, and hands. Sensitization to epoxy resins was detected in 4 workers, 1 of whom was also sensitized to epoxy curing agents. One worker was sensitized to bisphenol F resin but had a negative result with epoxy resin from the standard series. In the 5 remaining cases, the final diagnosis was irritant contact dermatitis due to fiberglass. Occupational skin diseases are increasingly common in the wind energy industry. The main allergens are epoxy resins. Fiberglass tends to produce irritation. Copyright © 2012 Elsevier España, S.L. and AEDV. All rights reserved.

  18. Changes in the poleward energy flux by the atmosphere and ocean as a possible cause for ice ages

    Energy Technology Data Exchange (ETDEWEB)

    Newell, R E

    1974-01-01

    It is proposed that the two preferred modes of temperature and circulation of the atmosphere which occurred over the past 100,000 yr correspond to two modes of partitioning of the poleward energy flux between the atmosphere and ocean. At present the ocean carries an appreciable fraction of the transport, for example about three-eighths at 30/sup 0/N. In the cold mode it is suggested that the ocean carries less, and the atmosphere more, than at present. During the formation of the ice, at 50,000 BP, for example, the overall flux is expected to be slightly lower than at present and during melting, at 16,000 BP, slightly higher. The transition between the modes is seen as a natural imbalance in the atmosphere-ocean energy budget with a gradual warming of the ocean during an Ice Age eventually culminating in its termination. At the present the imbalance is thought to correspond to a natural cooling of the ocean, which will lead to the next Ice Age. The magnitude of temperature changes in the polar regions differ between the hemispheres in the same way as present seasonal changes, being larger in the northern than in the southern hemisphere. Overall the atmospheric energy cycle was more intense during the Ice Ages than now. Observational tests are proposed by which predictions from the present arguments may be compared with deductions about the environment of the past. Data used for the present state of the atmospheric general circulation are the latest global data available and contain no known major uncertainties. However, data for the oceanic circulation and energy budget are less well known for the present and almost unknown for the past. Hence the proposed imbalances must be treated as part of a speculative hypothesis, but one which eventually may be subject to observational test as no solar variability is invoked.

  20. Wind energy input into the upper ocean over a lengthening open water season

    2017-12-01

    Wind energy input into the ocean has important consequences for upper ocean mixing, heat and gas exchange, and air-sea momentum transfer. In the Arctic, the open water season is increasing and extending further into the fall storm season, allowing for more wind energy input into the water column. The rate at which the delayed freeze-up timing extends into fall storm season is an important metric to evaluate because the expanding overlap between the open water period and storm season could contribute a significant amount of wind energy into the water column in a relatively short period of time. We have shown that time-integrated wind speeds over open water in the Chukchi Sea and southern Beaufort region have increased since 1979 through 2014. An integrated wind energy input value is calculated for each year in this domain over the open water season, as well as for periods over partial concentrations of ice cover. Spatial variation of this integrated wind energy is shown along the Alaskan coastline, which can have implications for different rates of coastal erosion. Spatial correlation between average wind speed over open water and open water season length from 1979-2014 show positive values in the southern Beaufort, but negative values in the northern Chukchi. This suggests possible differences in the role of the ocean on open water season length depending on region. We speculate that the warm Pacific water outflow plays a more dominant role in extending the open water season length in the northern Chukchi when compared to the southern Beaufort, and might help explain why we can show there is a relatively longer open water season length there. The negative and positive correlations in wind speeds over open water and open water season length might also be explained by oceanic changes tending to operate on longer timescales than the atmosphere. Seasonal timescales of wind events such as regional differences in overlap of the extended open water season due to regional

    2001-01-01

    For this study, we identified about 175 emerging energy-efficient technologies in industry, of which we characterized 54 in detail. While many profiles of individual emerging technologies are available, few reports have attempted to impose a standardized approach to the evaluation of the technologies. This study provides a way to review technologies in an independent manner, based on information on energy savings, economic, non-energy benefits, major market barriers, likelihood of success, and suggested next steps to accelerate deployment of each of the analyzed technologies. There are many interesting lessons to be learned from further investigation of technologies identified in our preliminary screening analysis. The detailed assessments of the 54 technologies are useful to evaluate claims made by developers, as well as to evaluate market potentials for the United States or specific regions. In this report we show that many new technologies are ready to enter the market place, or are currently under development, demonstrating that the United States is not running out of technologies to improve energy efficiency and economic and environmental performance, and will not run out in the future. The study shows that many of the technologies have important non-energy benefits, ranging from reduced environmental impact to improved productivity. Several technologies have reduced capital costs compared to the current technology used by those industries. Non-energy benefits such as these are frequently a motivating factor in bringing technologies such as these to market. Further evaluation of the profiled technologies is still needed. In particular, further quantifying the non-energy benefits based on the experience from technology users in the field is important. Interactive effects and inter-technology competition have not been accounted for and ideally should be included in any type of integrated technology scenario, for it may help to better evaluate market

  4. Waste energy recovery in the industry in the ECE region

    International Nuclear Information System (INIS)

    1985-01-01

    In the ECE region industry accounts for about 44 per cent of total final energy consumption, 50-55 per cent of which is ''lost''. Since the early 1970s the efficiency of energy use has improved by 5 or 6 percentage points. The potential for further cost-effective savings is estimated at 10 to 20 percentage points, depending on the type of industrial activity, kind of waste energy, availability of outlets, investment strategies, awareness of the significantly improved technical possibilities and degree of co-operation between energy specialists and production engineers, equipment manufacturers, and industrial sectors at the national and international levels. The present publication argues the case for secondary energy recovery (SER) by end-users and international co-operation in technical, economic, environmental and methodological fields. It is based on data compiled by the secretariat of the Economic Commission for Europe on 1 June 1984 and given general distribution. Refs, figs and tabs

    Hoffman, H. W.; Kedl, R. J.; Duscha, R. A.

    1978-01-01

    The potential is examined for waste heat recovery and reuse through thermal energy storage in five specific industrial categories: (1) primary aluminum, (2) cement, (3) food processing, (4) paper and pulp, and (5) iron and steel. Preliminary results from Phase 1 feasibility studies suggest energy savings through fossil fuel displacement approaching 0.1 quad/yr in the 1985 period. Early implementation of recovery technologies with minimal development appears likely in the food processing and paper and pulp industries; development of the other three categories, though equally desirable, will probably require a greater investment in time and dollars.

    Herrero Sola, Antonio Vanderley; Mota, Caroline Maria de Miranda; Kovaleski, Joao Luiz

    2011-01-01

    In the last years, several policies have been proposed by governments and global institutions in order to improve the efficient use of energy in industries worldwide. However, projects in industrial motor systems require new approach, mainly in decision making area, considering the organizational barriers for energy efficiency. Despite the wide application, multicriteria methods remain unexplored in industrial motor systems until now. This paper proposes a multicriteria model using the PROMETHEE II method, with the aim of ranking alternatives for induction motors replacement. A comparative analysis of the model, applied to a Brazilian industry, has shown that multicriteria analysis presents better performance on energy saving as well as return on investments than single criterion. The paper strongly recommends the dissemination of multicriteria decision aiding as a policy to support the decision makers in industries and to improve energy efficiency in electric motor systems. - Highlights: → Lack of decision model in industrial motor system is the main motivation of the research. → A multicriteria model based on PROMETHEE method is proposed with the aim of supporting the decision makers in industries. → The model can contribute to transpose some barriers within the industries, improving the energy efficiency in industrial motor system.

    In the last years, several policies have been proposed by governments and global institutions in order to improve the efficient use of energy in industries worldwide. However, projects in industrial motor systems require new approach, mainly in decision making area, considering the organizational barriers for energy efficiency. Despite the wide application, multicriteria methods remain unexplored in industrial motor systems until now. This paper proposes a multicriteria model using the PROMETHEE II method, with the aim of ranking alternatives for induction motors replacement. A comparative analysis of the model, applied to a Brazilian industry, has shown that multicriteria analysis presents better performance on energy saving as well as return on investments than single criterion. The paper strongly recommends the dissemination of multicriteria decision aiding as a policy to support the decision makers in industries and to improve energy efficiency in electric motor systems. - Highlights: > Lack of decision model in industrial motor system is the main motivation of the research. > A multicriteria model based on PROMETHEE method is proposed with the aim of supporting the decision makers in industries. > The model can contribute to transpose some barriers within the industries, improving the energy efficiency in industrial motor system.

    Full Text Available Voluntary environmental management systems (EMS based on the international standard ISO 14001 have become widespread globally in recent years. The purpose of this study is to assess the impact of voluntary management systems on energy efficiency in the Swedish manufacturing industry by means of objective industrial energy data derived from mandatory annual environmental reports. The study focuses on changes in energy efficiency over a period of 12 years and includes both ISO 14001-certified companies and non-certified companies. Consideration is given to energy improvement efforts in the companies before the adoption of ISO 14001. The analysis has been carried out using statistical methods for two different industrial energy parameters: electricity and fossil fuel consumption. The results indicate that ISO 14001 adoption and certification has increased energy efficiency regarding the use of fossil fuel. In contrast, no effect of the management systems has been found concerning the use of electricity. The mixed results of this study are only partly in line with the results of previous studies based on perceptions of company representatives.

    The energy sector in Europe is going through a dynamic evolution that sees the introduction and development of renewable energy and the re-emergence of a wave energy industry. Although wave energy is currently not economically competitive with mature technologies such as wind energy, the wave energy world-wide resource of 2 TW has a potential contribution in the electricity market of 2000TWh/year. Denmark, Ireland, Portugal, Norway and the UK have been analysed in terms of wave energy resources, renewable energy market structure and political and economic support for the introduction of wave energy into the marketplace. The results have been used together with Ocean Power Delivery Ltd to develop an initial market survey for the wave energy converter Pelamis. (au)

  14. How to promote energy conservation in China’s chemical industry

    Lin, Boqiang; Long, Houyin

    2014-01-01

    Fossil fuel consumption in China’s chemical industry accounted for 19.7% of the total industrial fossil fuel consumption, and the industry has become the second highest energy intensive sector in the country. Therefore, it is extremely urgent and important to study the problems related to fossil fuel consumption in the industry. This paper adopts the factor decomposition and the EG co-integration methods to investigate the influencing factors of fossil energy consumption and measure the saving potential of fossil fuel. The paper concludes that the influencing factors can be divided into positive driving factors (labor productivity effect and sector scale effect) and negative driving factors (energy intensity effect and energy structure effect). Among them, labor productivity and energy intensity are the main factors affecting fossil fuel demand. The largest saving potentials of fossil fuels are predicted to be 23.3 Mtce in 2015 and 70.6 Mtce in 2020 under the middle scenario and 46.8 Mtce in 2015 and 100.5 Mtce in 2020 under the ideal scenario, respectively. Finally, this paper provides some policy implications on fossil fuel conservation. - Highlights: • Labor productivity and energy intensity are crucial driving factors. • The relationship among variables is co-integrated. • The result of the EG co-integration is the same as that of LMDI. • ECM displays the short-term fluctuation of fossil fuel consumption. • Under the scenario analysis, there is a huge energy saving potential

    Many energy-intensive process industries have complex material flows, which have a strong effect on the overall energy intensity of the final product (OEIF). This problem, however, has only been recognised qualitatively due to the lack of quantitative analysis methods. This paper presents an in-depth quantitative analysis of the effect of material flows on energy intensity in process industries. Based on the concept of a standard material flow diagram (SMFD), as used in steel manufacturing, the SMFD for a generic process industry was first developed. Then material flow scenarios were addressed in a practical material flow diagram (PMFD) using the characteristics of practical process industries. The effect of each material flow deviating from a SMFD on the OEIF was analysed. The steps involved in analysing the effect of material flows in a PMFD on its energy intensity are also discussed in detail. Finally, using 1999 statistical data from the Chinese Zhenzhou alumina refinery plant, the PMFD and SMFD for this plant were constructed as a case study. The effect of material flows on the overall energy intensity of alumina (OEIA) was thus analysed quantitatively. To decrease OEIA, the process variations which decrease the product ratios could be employed in all except in multi-supplied fraction cases. In these cases, the fractions from the stream with lower energy intensities should be increased. (author)

    Boyd, G.; Fisher, R.; Hanson, D.; Ross, M.

    1989-01-01

    It has been recognized in a variety of studies that energy demand by industry has been effected not only by the changing energy intensity of the various sectors of industry, but also by the composition of industrial sector. A previous study group of the Energy Modeling Forum (EMF-8) found that sectoral shift, i.e., the relative decline in the energy intensive sectors of industry, has contributed at least one third of the decline in aggregate manufacturing energy intensity since the early 1970s. The specific types of energy use may also be important, however. For example, the effect of shifts in production by electricity intensive sectors has been shown to be somewhat different than that for fossil fuel

    Honma, Satoshi; Hu, Jin-Li

    2014-01-01

    Highlights: • This study compares Japan with other developed countries for energy efficiency at the industry level. • We compute the total-factor energy efficiency (TFEE) for industries in 14 developed countries in 1995–2005. • Energy conservation can be further optimized in Japan’s industry sector. • Japan experienced a slight decrease in the weighted TFEE from 0.986 in 1995 to 0.927 in 2005. • Japan should adapt energy conservation technologies from the primary benchmark countries: Germany, UK, and USA. - Abstract: Japan’s energy security is more vulnerable today than it was before the Fukushima Daiichi nuclear power plant accident in March 2011. To alleviate its energy vulnerability, Japan has no choice but to improve energy efficiency. To aid in this improvement, this study compares Japan’s energy efficiency at the industry level with that of other developed countries. We compute the total-factor energy efficiency (TFEE) of industries in 14 developed countries for 1995–2005 using data envelopment analysis. We use four inputs: labor, capital stock, energy, and non-energy intermediate inputs. Value added is the only relevant output. Results indicate that Japan can further optimize energy conservation because it experienced only a marginal decrease in the weighted TFEE, from 0.986 in 1995 to 0.927 in 2005. To improve inefficient industries, Japan should adapt energy conservation technologies from benchmark countries such as Germany, the United Kingdom, and the United States

    International Nuclear Information System (INIS)

    1997-01-01

    This report documents the objectives, analytical approach, and development of the National Energy Modeling System (NEMS) Industrial Demand Model. The report catalogues and describes model assumptions, computational methodology, parameter estimation techniques, and model source code. This document serves three purposes. First, it is a reference document providing a detailed description of the NEMS Industrial Model for model analysts, users, and the public. Second, this report meets the legal requirement of the Energy Information Administration (EIA) to provide adequate documentation in support of its models. Third, it facilitates continuity in model development by providing documentation from which energy analysts can undertake model enhancements, data updates, and parameter refinements as future projects. The NEMS Industrial Demand Model is a dynamic accounting model, bringing together the disparate industries and uses of energy in those industries, and putting them together in an understandable and cohesive framework. The Industrial Model generates mid-term (up to the year 2015) forecasts of industrial sector energy demand as a component of the NEMS integrated forecasting system. From the NEMS system, the Industrial Model receives fuel prices, employment data, and the value of industrial output. Based on the values of these variables, the Industrial Model passes back to the NEMS system estimates of consumption by fuel types

  19. Limits to leapfrogging in energy technologies? Evidence from the Chinese automobile industry

    International Nuclear Information System (INIS)

    Gallagher, Kelly Sims

    2006-01-01

    Limits to leapfrogging in energy technologies? One of the most attractive notions in the field of sustainable energy development is the concept of energy-technology 'leapfrogging'. Leapfrogging through international technology transfer can be especially problematic because often developing countries do not have the technological capabilities to produce or integrate the advanced energy technologies themselves. Until they have acquired the capabilities to produce the advanced technologies themselves, most late-industrializing countries buy their new technologies from industrialized countries, usually through licensing or joint-venture arrangements. Empirical case studies of the three main Sino-US passenger-car joint ventures reveal that until the late 1990s, little energy or environmental leapfrogging occurred in the Chinese automobile industry as the result of the introduction of US automotive technology. An improvement in Chinese capabilities and more stringent Chinese energy and environmental policies are needed to induce energy leapfrogging in the Chinese automobile industry. Foreign firms also have a social responsibility to contribute to China's sustainable industrial development. In order to realize the promise of the leapfrogging, the limits to leapfrogging must be identified and acknowledged so that strategies can be devised to surmount the barriers to the introduction of advanced energy technologies in developing countries

    Feijoo, Maria L.; Hernandez, Jose M.; Franco, Juan F.

    2002-01-01

    This paper uses a stochastic frontier production function model to analyze the energy efficiency of Spanish industry. We used minimum cost input demand equations as the reference in order to calculate the demand for electricity, gas and other fuels. On this basis, we found that there is no inherent conflict between the objectives of achieving productive efficiency and reducing energy consumption. Indeed, it is possible to reduce the industrial emissions of CO 2 by up to 29.4% by means of a bottom-up energy efficiency policy. However, if the government wants firms to reduce their emissions even further, then it would be necessary to implement some form of energy regulatory policy. In this respect, we estimate the cost of reducing CO 2 emissions by 20%

    1998-01-01

    Today I want to make two key points about the U.S. nuclear energy industry. First, key policy issues are beginning to converge in a way that is very positive for our industry - and for society as a whole. And Second, the industry has worked hard to prepare for the future - and we are ready to make the most of these positive developments. Nuclear energy's prospects are the brightest they have been at any time in history. The plan identifies the building blocks that must be in place before utilities start building the next generation of nuclear plants. One, we wanted to improve the efficiency and reliability of our operating nuclear plants. Two, we wanted to establish a regulatory framework for license renewal. Three, we wanted to develop a more efficient licensing process for new plants. In closing, I am confident that the 21st century will bring a renaissance for nuclear energy-in the United States and around the world. The U.S. nuclear energy industry has a renewed vitality and sense of mission today. We've worked hard preparing for the future- and we will continue to be strong players in worldwide energy policy development in the 21st century. (Cho, G. S.)

    1981-05-01

    Several issues are analyzed on the effects that government subsidies and other incentives have on the use of solar energy in industry, as well as on other capital-intensive alternative energy supplies. Discounted cash flow analysis is used to compare tax deductions for fuel expenses with tax credits for capital investments for energy. The result is a simple expression for tax equity. The effects that market penetration of solar energy has on conventional energy prices are analyzed with a free market model. It is shown that net costs of a subsidy program to the society can be significantly reduced by price. Several government loan guarantee concepts are evaluated as incentives that may not require direct outlays of government funds; their relative effectiveness in achieving loan leverage through project financing, and their cost and practicality, are discussed.

  5. A calibrated energy end-use model for the U.S. chemical industry

    Ozalp, N.; Hyman, B.

    2005-01-01

    The chemical industry is the second largest energy user after the petroleum industry in the United States. This paper provided a model for onsite steam and power generation in the chemical industry, as well as an end-use of the industrial gas manufacturing sector. The onsite steam and power generation model included the actual conversion efficiencies of prime movers in the sector. The energy end-use model also allocated combustible fuel and renewable energy inputs among generic end-uses including intermediate conversions through onsite power and steam generation. The model was presented in the form of a graphical depiction of energy flows. Results indicate that 35 per cent of the energy output from boilers is used for power generation, whereas 45 per cent goes directly to end-uses and 20 per cent to waste heat tanks for recovery in the chemical industry. The end-use model for the industrial gas manufacturing sector revealed that 42 per cent of the fuel input goes to onsite steam and power generation, whereas 58 per cent goes directly to end-uses. Among the end-uses, machine drive was the biggest energy user. It was suggested that the model is applicable to all other industries and is consistent with U.S. Department of Energy data for 1998. When used in conjunction with similar models for other years, it can be used to identify changes and trends in energy utilization at the prime mover level of detail. An analysis of the economic impact of energy losses can be based on the results of this model. Cascading of waste heat from high temperature processes to low temperature processes could be integrated into the model. 20 refs., 4 tabs., 8 figs

    Graphical abstract: Major cities in eight economy-geography regions of China. - Highlights: • Industrial energy and emissions efficiency were evaluated for China’s major cities. • Shadow prices of CO 2 emissions were estimated for China’s major cities. • Efficiency increase potentials on energy utilization and CO 2 emissions are 19% and 17%. • N-shaped EKC exists between levels of CO 2 emissions efficiency and income. • Average industrial CO 2 emissions abatement cost for China’s major cities is 45 US$. - Abstract: Evaluating the energy and emissions efficiency, measuring the energy saving and emissions reduction potential, and estimating the carbon price in China at the regional level are considered a crucial way to identify the regional efficiency levels and efficiency promotion potentials, as well as to explore the marginal abatement costs of carbon emissions in China. This study applies a newly developed Data Envelopment Analysis (DEA) based method to evaluate the regional energy and emissions efficiencies and the energy saving and emissions reduction potentials of the industrial sector of 30 Chinese major cities during 2006–2010. In addition, the CO 2 shadow prices, i.e., the marginal abatement costs of CO 2 emissions from industrial sector of these cities are estimated during the same period. The main findings are: (i) The coast area cities have the highest total factor industrial energy and emissions efficiency, but efficiency of the west area cities are lowest, and there is statistically significant efficiency difference between these cities. (ii) Economically well-developed cities evidence higher efficiency, and there is still obviously unbalanced and inequitable growth in the nationwide industrial development of China. (iii) Fortunately, the energy utilization and CO 2 emissions efficiency gaps among different Chinese cities were decreasing since 2006, and the problem of inequitable nationwide development has started to mitigate.

    2013-01-01

    Steam systems consume approximately one third of energy applied at US industrial facilities. To reduce energy consumption, steam system energy assessments have been conducted on a wide range of industry types over the course of 5 years through the Energy Savings Assessment (ESA) program administered by the US Department of Energy (US DOE). ESA energy assessments result in energy efficiency measure recommendations that are given potential energy and energy cost savings and potential implementation cost values. Saving and cost metrics that measure the impact recommended measures will have at facilities, described as percentages of facility baseline energy and energy cost, are developed from ESA data and used in analyses. Developed savings and cost metrics are examined along with implementation and rejection rates of recommended steam system energy efficiency measures. Based on analyses, implementation of steam system energy efficiency measures is driven primarily by cost metrics: payback period and measure implementation cost as a percentage of facility baseline energy cost (implementation cost percentage). Stated reasons for rejecting recommended measures are primarily based upon economic concerns. Additionally, implementation rates of measures are not only functions of savings and cost metrics, but time as well. - Highlights: ► We examine uptake/rejection of industrial steam system energy efficiency measures. ► We examine metrics that correspond to uptake/rejection of recommended measures. ► We examine barriers hindering steam system energy efficiency measure implementation. ► Uptake/rejection of steam measures is linked to potential cost metrics. ► Increased uptake of measures and uptake of more costly measures increases with time

    Countries with large stock of fissile material and producing large quantity of nuclear pure 235 U and 239 Pu are able to allocate part of the stock to non military research. For countries with low stock of fissile material, all the stock is allocated to military research. An economical and technical solution has to be find to dedicate a part of fissile material to non military research and develop the atomic energy industry. It stated the industrial and economical problems and in particular the choice between the use of enriched fuel with high refining cost or depleted fuel with low production cost. It discusses of four possible utilizations of the natural resources: reactors functioning with pure fissile material ( 235 U or 239 Pu) or concentrated material ( 235 U mixed with small quantities of 238 U after an incomplete isotopic separation), breeder reactors functioning with enriched material mixed with 238 U or Thorium placed in an appropriate spatial distribution to allow neutrons beam to activate 238 U or Thorium with the regeneration of fissile material in 239 Pu, reactors using natural uranium or low enriched uranium can also produce Plutonium with less efficiency than breeder reactors and the last solution being the use of natural uranium with the only scope of energy production and no production of secondary fissile material. The first class using pure fissile material has a low energy efficiency and is used only by large fissile material stock countries to accumulate energy in small size fuel for nuclear engines researches for submarines and warships. The advantage of the second class of reactors, breeder reactors, is that they produce energy and plutonium. Two type of breeder reactor are considered: breeder reactor using pure fissile material and 238 U or breeder reactor using the promising mixture of pure fissile material and Thorium. Different projects are in phase of development in United States, England and Scotland. The third class of reactor using

    The United States railroad industry plays a key role in transporting materials to support our industrial economy. One of the oldest industries in the US, the railroads have developed over 150 years into their present physical and operational configuration. Energy conservation proposals to change industry facilities, equipment, or operating practices must be evaluated in terms of their cost impact. A current, comprehensive and accurate data baseline of railroad economic activity and energy consumption is presented. Descriptions of the history of railroad construction in the US and current equipment, facilities, and operation practices follow. Economic models that relate cost and energy of railroad service to the volume of railroad output and to physical and operational parameters are provided. The analyses and descriptions should provide not only an analytical baseline for evaluating the impact of proposed conservation measures, but they should also provide a measure of understanding of the system and its operations to analysts and policy makers who are involved in proposing, analyzing, and implementing such changes.

    A survey of the key issues associated with the development in the Chinese iron and steel industry and current situations of energy consumption are described in this paper. The apparent production of crude steel in China expanded to 418.78 million tonnes in 2006, which was about 34% share of the world steel production. The iron and steel industry in China is still one of the major high energy consumption and high pollution industries, which accounts for the consumption of about 15.2% of the national total energy, and generation of 14% of the national total wastewater and waste gas and 6% of the total solid waste materials. The average energy consumption per unit of steel is about 20% higher than that of other advanced countries due to its low energy utilization efficiency. However, the energy efficiency of the iron and steel industry in China has made significant improvement in the past few years and significant energy savings will be achieved in the future by optimizing end-use energy utilization. Finally, some measures for the industry in terms of the economic policy of China's 11th five-year plan are also presented.

    Presently, the industrial sector is responsible for 21% of energy consumption in Morocco. Fully aware about the challenge of reducing energy consumption and related CO_2 emissions by industries, Moroccan authorities have legislated under the new law (n° 47-09 related to energy efficiency) the obligation of energy audit in Moroccan industries. In such a context, this paper is a Level II energy audit (conforming to ASHRAE classification) performed for an industrial site based in Fez (Morocco) specialized in producing and commercializing cattle feed. A detailed analysis of the characteristics of the energy use has identified a mismanagement of the electrical energy. Through the improvement of the DPF (displacement power factor) to a value of 0.98, it was shown that the factory can save about 52758.74 US$ annually. An improvement of energy efficiency of the interior lighting was also performed. The proposed action concerned the voltage regulation and has the potential of reducing 13.6% of the lighting energy consumption with the mitigation of approximately 27 533 of CO_2/year. Furthermore, harmonic treatment by installing passive filters for VSD (variable speed drives) was carried out. The energy savings related to the harmonic treatment were evaluated to be 26 760 kWh/year. - Highlights: • Detailed analysis of energy use in an industrial site in Morocco. • New method of improving energy efficiency for the interior lighting. • Harmonic treatment using a simulation program. • Economic and environmental evaluation of proposed actions.

    This research program addresses the need to increase the energy efficiency of industrialized housing. Two research centers have responsibility for the program: the Center for Housing Innovation at the University of Oregon and the Florida Solar Energy Center, a research institute of the University of Central Florida. The two organizations provide complementary architectural, systems engineering, and industrial engineering capabilities. In 1989 we worked on these tasks: (1) the formation of a steering committee, (2) the development of a multiyear research plan, (3) analysis of the US industrialized housing industry, (4) assessment of foreign technology, (5) assessment of industrial applications, (6) analysis of computerized design and evaluation tools, and (7) assessment of energy performance of baseline and advanced industrialized housing concepts. The current research program, under the guidance of a steering committee composed of industry and government representatives, focuses on three interdependent concerns -- (1) energy, (2) industrial process, and (3) housing design. Building homes in a factory offers the opportunity to increase energy efficiency through the use of new materials and processes, and to increase the value of these homes by improving the quality of their construction. Housing design strives to ensure that these technically advanced homes are marketable and will meet the needs of the people who will live in them.

    This paper investigates the effect of disaggregate energy consumption on industrial output in the United States. Most of the related research utilizes aggregate data which may not indicate the relative strength or explanatory power of various energy inputs on output. We use monthly data and employ the generalized variance decomposition approach to assess the relative impacts of energy and employment on real output. Our results suggest that unexpected shocks to coal, natural gas and fossil fuel energy sources have the highest impacts on the variation of output, while several renewable sources exhibit considerable explanatory power as well. However, none of the energy sources explain more of the forecast error variance of industrial output than employment

    Highlights: ► We evaluate energy efficiency under framework of total factor energy efficiency. ► We focus on industry sector of China. ► We use statistical data of industrial enterprises above designated size. ► Energy efficiencies among regions in China are obvious because of technological differences. ► Large scale of investment should be stopped especially in central and western regions. -- Abstract: The rapid growth of the Chinese economy has resulted in great pressure on energy consumption, especially the energy intensive sector – the industrial sector. To achieve sustainable development, China has to consider how to promote energy efficiency to meet the demand of Chinese rapid economic growth, as the energy efficiency of China is relatively low. Meanwhile, the appeal of energy saving and emission reduction has been made by the Chinese central government. Therefore, it is important to evaluate the energy efficiency of industrial sector in China and to assess efficiency development probabilities. The framework of total factor energy efficiency index is adopted to determine the discrepancy of energy efficiency in Chinese industrial sector based on the provincial statistical data of industrial enterprises above designated size in 30 provinces from 2005 to 2009, with gross industrial output as the output value and energy consumption, average remaining balance of capital assets and average amount of working force as the input values. Besides, in considerate of the regional divide of China, namely eastern, central, and western, and economic development differences in each region, energy efficiency of each region is also analysed in this paper. The results show that there is room for China to improve its energy efficiency, especially western provinces which have large amount of energy input excess. Generally speaking, insufficient technological investment and fail of reaching best scale of manufacture are two factors preventing China from energy

  2. The patterns of energy use in the chemical industry

    Steinmeyer, D.

    1997-01-01

    This paper was sculpted from a report commissioned by the Department of Energy to assess the impact of proposed energy taxes on energy use by the US chemical industry. The discussion of energy taxes is eliminated here, however the broader discussion of the impact of energy prices on energy use is retained. The US chemical industry is currently the world leader by many important measures, such as technology contributions and employment. This leadership traces to a slate of advantages: science base, low cost energy, large market and economic/political stability. The focus of this paper is on the patterns of energy use: (1) There is an optimum economic trade of capital against energy. Industry optimizes this trade to lower its costs. For the large volume chemicals which dominate energy use, this tradable capital cost exceeds energy cost by a factor of 1.5. (2) The capital/energy trade follows clearly defined rules. The basic rules are rooted in thermodynamics. (3) An increase in energy prices would result in a drop in process energy use: a doubling of process energy prices would cut process energy use by approximately 1/3 but the capital cost would be in excess of $100 billion if driven into a short time span, such as 5 years. This is because of the long useful lifetime of capital facilities. (4) Process energy is about half the total energy use, with feedstock being the balance. Feedstock use is much less sensitive to price. Restated, the doubling of energy price will result in roughly a 1/6 reduction in total energy use. (5) Technology progress will also reduce energy use. This reduction is distinct from the impact of energy price. Technological progress will be at least as important in reducing energy use as will energy pricing, for the foreseeable future. (6) Technology progress can be sorted into two themes: (a) Learning curve improvements, which are almost inherent in the production process and the nature of competition; and (b) Breakthroughs that happen in a

    Industrial demand accounts for about 30% of total final energy demand in Thailand, which experienced rapid increases in energy demand. This paper analyzes the changes in industrial energy intensities over a period of 20 years (1981-2000) and identifies the factors affecting the energy consumption using logarithmic mean Divisia decomposition technique. It is found that Thai industry has passed through four different phases of growth and energy consumption has closely followed the industrial growth pattern. Energy intensity of Thai industry decreased from 17.6 toe/million baht (constant 1988 prices) in 1981 to 15.8 toe/million baht (1988 prices) in 2000. Non-metallic mineral industry is the most intensive industry followed by basic metal, food and beverage, chemical and paper industries. The factor analysis indicates that both the structural effect and intensity effect contributed to a decline of aggregate intensity by 8% during 1981-1986 but in the rest of the periods, the two effects acted in opposite directions and thereby reducing the overall effect on aggregate intensity. Food and beverages, non-metallic mineral and chemical industries had significantly influenced the changes in aggregate intensity at sectoral level

    A survey was carried out to make available the information base that can collect, put into order and provide quickly and accurately the energy related information based on global environment problems in the Pacific Ocean region. Fiscal 1998 has performed a substituting energy demand and supply analysis in the Pacific Ocean region by adding the 1996 data, in addition to collection of the normal energy data. For the purpose of analyzing the petroleum substituting energy demand and supply in the Pacific Ocean region, data were collected from 17 countries for fiscal 1997 and the quarterly data for 1998. Retroactive data collection was also continued. The growth rate of primary energy supply in the Pacific Ocean region is 1.8% in average in the 1980's, and 3.8% in the 1990's. In contrast, the growth rate of petroleum substituting energies is 6.4% in the 80's and 6.2% in the former half of the 90's, being far higher than the growth rate of the primary energy supply. The share of the petroleum substituting energies accounting for in the primary energy supply has increased from 6.7% in 1980 to 12.1% in 1996. As the breakdown, nuclear power accounts for overwhelmingly large, followed by geothermal energy and new energies. (NEDO)

    'The Use of Nuclear Power for Peaceful Purposes' is a key topic in energy policy which produces a split of opinions in Germany, and which the policy of the Grand Coalition seeks to bypass. The Federation of German Industries (BDI) wants to achieve a sensible way of handling this source of energy because, after all, we are facing the challenge of having to secure economic development and prosperity and, at the same time, reduce global CO{sub 2} emissions. If this is to be achieved, industry and politics together must build a bridge into a future with less CO{sub 2}. That bridge would be supported on 4 pillars: - a global strategy of CO{sub 2} reduction, - energy efficiency, - a broad energy mix, - energy research and development. In these efforts, industry and the BDI consider nuclear power an indispensable part of a viable climate and energy policy. Next to lignite, nuclear power offers electricity generation at the lowest cost, and promotes climate protection through CO{sub 2}-free generation. As far as energy efficiency and a broad energy mix are concerned, the potentials for technical development play an important role. This is an area in which German industry can develop future markets for itself by being a leader in technology. Energy research should advance the development of existing technologies and open up new options. In this way, energy research contributes to high technologies in Germany. For nuclear power, it must be ensured that German scientists are able to participate in promising developments of new reactors in the same way in which this is the case in the development and construction of ITER, the international fusion reactor, in France.

    In summer 2002 The Algemene Energieraad (General Energy Council) of The Netherlands has commissioned a research study to investigate the strategic behaviour of major European energy companies and the major governmental institutions in charge of regulating them. In total 18 electricity and gas companies and 9 governmental public institutions were analyzed. The aim of this research was to explore how the microeconomic view of analysing company and government strategy can contribute to understanding the likely future path of the energy industry, and what follows from that for the regulatory agenda and company strategy development. The is structured in seven chapters. The first chapter will first outline what the challenges for the European energy industry are. Most of the challenges result in the need for high investments and considerable changes in operating systems and business models. Against these challenges, the second chapter outlines what the expectations are of the industry. The public goods to be delivered by the industry is in the main to deliver high quality products at low prices and minimized environmental impact, in order to promote the conditions for economic growth of the European economy. Chapter 3 then describes the typical behaviour of the energy companies, being mostly engaged in a strategic conduct that is autonomy-oriented, short term and emergent planning with an international focus. Chapter 4 explains how the challenges and expectations could be better met with a strategic behaviour of companies that are network-oriented, long term deliberate planners and with a local focus. Chapter 5 explains that the observed strategic behaviour leads to an industrial structure that is geared towards maintaining static competition and avoiding innovation. Chapter 6 shows, how the current regulatory regime of the industry may reinforce this static competition even further. Chapter 7 finally concludes with alternative course of actions how the regulatory

    The energy crisis did abound before the Arab oil embargo, so says Leo Blatz, but that action did bring the crisis to the fore. This action further brought about a change in attitudes. In this interview, Mr. Blatz commented on the reasons for the crisis, wastefulness in energy consumption; cost to the U.S. to import oil; reinstatement of coal usage; renewable energy source development and the time lag in this area; reasons for the lack of understanding; profits in industry; ways to solve problems between lifestyle and energy consumption; reserving petroleum supplies for much needed petrochemicals; environmental impacts; and where the responsibility lies. He says industry is tagged as the polluter, but ''industry is nothing but a collection of human beings.'' (MCW)

    Assumptions regarding the magnitude and direction of energy-related technological change have long been recognized as critical determinants of the outputs and policy conclusions derived from integrated assessment models. Particularly in the case of developing countries, however, empirical analysis of technological change has lagged behind simulation modeling. This paper presents estimates of sectoral productivity trends and energy-augmenting technological change for several energy-intensive industries in India and South Korea, and, for comparison, the United States. The key findings are substantial heterogeneity among both industries and countries, and a number of cases of declining energy efficiency. The results are subject to certain technical qualifications both in regards to the methodology and to the direct comparison to integrated assessment parameterizations. Nevertheless, they highlight the importance of closer attention to the empirical basis for common modeling assumptions

  9. Energy efficiency in industry and transportation

    Ruscoe, J.

    1990-01-01

    The discussion of energy issues has changed since the 1970s as improvements have been made in energy efficiency. The present capacity for surplus energy production in economically advanced countries reflects a decrease in energy requirements as well as new production sources. At the same time, the energy crisis can be seen as having discouraged improvements in energy efficiency because of its negative impact on growth. And the centrally planned economies remain highly inefficient energy users. Economic growth encourages the use of new technologies which are likely to be less energy-intensive than those they replace. Permanent gains in energy efficiency are derived from structural changes in the economy and from the introduction of energy-efficient technologies. This article addresses the prospect of increased energy conservation, particularly in industry (the end-use which consumes the most energy) and transportation. Although investments in projects to promote energy conservation are more cost-effective and environment-friendly than investments in energy supply, there is still widespread support for the latter. Developing countries naturally give preference to quantitative growth, with an increasing consumption of energy, but in these countries, too, more efficient use of energy could greatly reduce demand. The policies of international development agencies which still favour increasing energy supply over conservation need to change. Awareness of the need to reduce energy demand is, however, growing worldwide. (author)

    This paper reviews the literature concerning the energy saving and outlines the importance of energy efficiency, particularly in three the most important areas: buildings, industry and transportation. Improving energy efficiency plays a crucial role in minimizing the societal and environmental impacts of economic growth and offers a powerful tool for achieving sustainable development by reducing the need for investment in new infrastructure, by cutting fuel costs, and by increasing competitiveness for businesses and welfare for consumers. It creates environmental benefits through reduced emissions of greenhouse gases and local air pollutants. It can offer social benefits in the form of increased energy security (through reduced dependence on fossil fuels, particularly when imported) and better energy services.

    In the Paris Agreement in 2015 countries agreed on holding global mean surface air warming to well below 2 °C above pre-industrial levels, but the emission reduction pledges under that agreement are not ambitious enough to meet this target. Therefore, the question arises of whether restoring global warming to this target after exceeding it by artificially removing CO2 from the atmosphere is possible. One important aspect is the reversibility of ocean heat uptake and associated sea level rise, which have very long (centennial to millennial) response timescales. In this study the response of sea level rise due to thermal expansion to a 1 % yearly increase of atmospheric CO2 up to a quadrupling of the pre-industrial concentration followed by a 1 % yearly decline back to the pre-industrial CO2 concentration is examined using the University of Victoria Earth System Climate Model (UVic ESCM). We find that global mean thermosteric sea level (GMTSL) continues to rise for several decades after atmospheric CO2 starts to decline and does not return to pre-industrial levels for over 1000 years after atmospheric CO2 is restored to the pre-industrial concentration. This finding is independent of the strength of vertical sub-grid-scale ocean mixing implemented in the model. Furthermore, GMTSL rises faster than it declines in response to a symmetric rise and decline in atmospheric CO2 concentration partly because the deep ocean continues to warm for centuries after atmospheric CO2 returns to the pre-industrial concentration. Both GMTSL rise and decline rates increase with increasing vertical ocean mixing. Exceptions from this behaviour arise if the overturning circulations in the North Atlantic and Southern Ocean intensify beyond pre-industrial levels in model versions with lower vertical mixing, which leads to rapid cooling of the deep ocean.

    Industrial boilers are widely applied in such fields as factory power, building heating, and people’s lives; China is the world’s largest producer and user of industrial boilers, with very high annual energy consumption; clear requirements have been put forward by China on the energy efficiency since the “11th Five-year Plan” with the hope to save energy and reduce emission by means of energy efficiency standards and regulations on the supervision and control of various special equipment. So far, the energy efficiency of industrial boilers in China has been improved significantly but there is still a gap with the EU states. This paper analyzes the policies of energy efficiency, implementation models and methods of supervision and implementation at the EU level from laws, regulations, directives as well as standards; the paper also puts forward suggestions of energy conserving and emission reduction on the improvement of energy conserving capacity of industrial boilers in China through studying the legislations and measures of the developed countries in energy conserving of boilers.

    Corn wet milling is the most energy intensive industry within the food and kindred products group (SIC 20), using 15 percent of the energy in the entire food industry. After corn, energy is the second largest operating cost for corn wet millers in the United States. A typical corn wet milling plant in the United States spends approximately $20 to $30 million per year on energy, making energy efficiency improvement an important way to reduce costs and increase predictable earnings, especially in times of high energy-price volatility. This report shows energy efficiency opportunities available for wet corn millers. It begins with descriptions of the trends, structure and production of the corn wet milling industry and the energy used in the milling and refining process. Specific primary energy savings for each energy efficiency measure based on case studies of plants and references to technical literature are provided. If available, typical payback periods are also listed. The report draws upon the experiences of corn, wheat and other starch processing plants worldwide for energy efficiency measures. The findings suggest that given available resources and technology, there are opportunities to reduce energy consumption cost-effectively in the corn wet milling industry while maintaining the quality of the products manufactured. Further research on the economics of the measures, as well as the applicability of these to different wet milling practices, is needed to assess the feasibility of implementation of selected technologies at individual plants.

    Europe's offshore wind potential is enormous and able to power Europe seven times over. Over 100 GW of offshore wind projects are already in various stages of planning. If realised, these projects would produce 10% of the EU's electricity whilst avoiding 200 million tonnes of CO2 emissions each year. EWEA has a target of 40 GW of offshore wind in the EU by 2020, implying an average annual market growth of 28% over the coming 12 years. The EU market for onshore wind grew by an average 32% per year in the 12-year period from 1992-2004 - what the wind energy industry has achieved on land can be repeated at sea. EWEA's proposed offshore grid builds on the 11 offshore grids currently operating and 21 offshore grids currently being considered by the grid operators in the Baltic and North Seas to give Europe a truly pan-European electricity super highway. Strong political support and action from Europe's policy-makers will allow a new, multi-billion euro industry to be built. This new industry will deliver thousands of green collar jobs and a new renewable energy economy and establish Europe as world leader in offshore wind power technology. A single European electricity market with large amounts of wind power will bring affordable electricity to consumers, reduce import dependence, cut CO2 emissions and allow Europe to access its largest domestic energy source.

    In 2002, the United States Department of Energy (USDOE) published an energy efficiency assessment of U.S. industrial sector motor systems titled United States Industrial Electric Motor Systems Market Opportunities Assessment. The assessment advanced motor system efficiency by providing a greater understanding of the energy consumption, use characteristics, and energy efficiency improvement potential of industrial sector motor systems in the U.S. Since 2002, regulations such as Minimum Energy Performance Standards, cost reductions for motor system components such as variable frequency drives, system-integrated motor-driven equipment, and awareness programs for motor system energy efficiency have changed the landscape of U.S. motor system energy consumption. To capture the new landscape, the USDOE has initiated a three-year Motor System Market Assessment (MSMA), led by Lawrence Berkeley National Laboratory (LBNL). The MSMA will assess the energy consumption, operational and maintenance characteristics, and efficiency improvement opportunity of U.S. industrial sector and commercial building motor systems. As part of the MSMA, a significant effort is currently underway to conduct field assessments of motor systems from a sample of facilities representative of U.S. commercial and industrial motor system energy consumption. The Field Assessment Plan used for these assessments builds on recent LBNL research presented at EEMODS 2011 and EEMODS 2013 using methods for characterizing and determining regional motor system energy efficiency opportunities. This paper provides an update on the development and progress of the MSMA, focusing on the Field Assessment Plan and the framework for assessing the global supply chain for emerging motors and drive technologies.

    Energy efficiency is a highly important topic and currently omnipresent in the energy political discussion. Despite this high importance there's no common understanding even concerning the definition of the term energy efficiency. In addition, there are plenty so called energy efficiency targets and several indicators. Therefore this study should provide a deepened understanding of the efficient use of energy. The inconsistent definition of energy efficiency is related to the use of this term for a specific as well as an absolute reduction of energy consumption. Furthermore both static views on efficiency as a status and also dynamic views on efficiency as an improvement of a value compared to a reference number are used. Additional differences occur in the evaluation of the energy use and in the selection of a reference value in a key figure to assess energy efficiency. Moreover the focus of the current general understanding is mainly only on the consumption of energy. All other resources next to the energy input which are needed to provide energy services are not considered even though there are strong interactions and substitution possibilities among these resources. Hence the understanding of energy efficiency is extended in this study by these additional resources which were not considered yet. Based on this extension the efficient use of the resource energy is a result of an optimisation of the relation of these total costs of all resources to the related benefit. To determine the efficient use of energy in the industrial sector, a deeper understanding of the sector and its characteristics is necessary. The industrial sector is the largest consumer of electricity within the EU. Also a quarter of the final energy consumption and about 20 % of the CO 2 emissions are related to this sector. Typical for this sector are the heterogeneous and high temperature level of the heat demand and the process emissions which accrue in transformation processes. The subsectors

    This study examines the integration of the Brazilian economy in the global economy as a determining factor for the energy efficiency of its industry. Depending upon the profile of a country's exports (i.e., depending upon the share of energy-intensive exports out of total exports), different quantities of energy are required to produce the country's exported goods, which may counterbalance efforts made elsewhere to improve the overall energy efficiency of the country's industry. Different scenarios for the energy embodied in the industrial exports of Brazil are considered for the period 1995--2015. These scenarios are a combination of different shares of energy-intensive goods in the total exports of the country with different assumptions for gains obtained in industrial energy efficiency over time. For all scenarios the same fundamental hypothesis of liberalization of commerce and economic growth are assumed. Results for the year 2015 show that the total energy embodied in industrial exports varies from 1,413 PJ to 2,491 PJ, and the total industrial use of energy varies from 3,858 PJ to 6,153 PJ, depending upon the assumptions made. This is equivalent to an average industrial energy intensity variation ranging from 13.8 MJ to 22.0 MJ per US$-1985. The authors conclude that any policy aimed at improving Brazil's overall industrial energy efficiency should concentrate not only on the reduction of the energy intensity of particular industrial sectors, but also (and, perhaps, more importantly) on rethinking the very strategy for the integration of the country's economy in the global market in the future, with respect to the share of energy-intensive goods out of total exports. The focus is not incidental, for the ongoing structural changes in Brazilian exports alone may come to offset any efficiency improvements achieved by the national industry as a whole

    The Bonneville Power Administration (Bonneville) has identified 101 plants in the Pacific Northwest that account for 80% of the region's industrial electricity consumption. These plants offer a precise target for a conservation program. PNL determined that most of these 101 plants were represented by 11 major industries. We then reviewed 36 major conservation technologies used in these 11 industrial settings to determine their potential environmental impacts. Energy efficiency technologies designed for industrial use may result in direct or indirect environmental impacts. Effects may result from the production of the conservation measure technology, changes in the working environment due to different energy and material requirements, or changes to waste streams. Industry type, work-place conditions, worker training, and environmental conditions inside and outside the plant are all key variables that may affect environmental outcomes. To address these issues this report has three objectives: Describe potential conservation measures that Bonneville may employ in industrial programs and discuss potential primary impacts. Characterize industrial systems and processes where the measure may be employed and describe general environmental issues associated with each industry type. Review environmental permitting, licensing, and other regulatory actions required for industries and summarize the type of information available from these sources for further analysis.

    Many states have implemented ratepayer-funded programs to acquire energy efficiency as a predictable and reliable resource for meeting existing and future energy demand. These programs have become a fixture in many U.S. electricity and natural gas markets as they help postpone or eliminate the need for expensive generation and transmission investments. Industrial energy efficiency (IEE) is an energy efficiency resource that is not only a low cost option for many of these efficiency programs, but offers productivity and competitive benefits to manufacturers as it reduces their energy costs. However, some industrial customers are less enthusiastic about participating in these programs. IEE ratepayer programs suffer low participation by industries across many states today despite a continual increase in energy efficiency program spending across all types of customers, and significant energy efficiency funds can often go unused for industrial customers. This paper provides four detailed case studies of companies that benefited from participation in their utility’s energy efficiency program offerings and highlights the business value brought to them by participation in these programs. The paper is designed both for rate-payer efficiency program administrators interested in improving the attractiveness and effectiveness of industrial efficiency programs for their industrial customers and for industrial customers interested in maximizing the value of participating in efficiency programs.

    Energy management is a system of managing energy utilization wisely and it includes issues such as energy efficiency (conservation), use of renewable energy, use of technology and development of energy policy. Its benefits has been well known for cost reduction and increase competitiveness and also other indirect impact such as preserving the natural resources and reduction of green-house gases. Although various strategies have been formulated by the government for the industries to adopt energy management, the result seems to be minimal and stagnant in some ways due to the various barriers which exists. Industries on the other hand, have successfully welcomed two famous management system namely the Environmental Management System ISO 14000 and the Quality Management System ISO 9000 to be implemented at their premises. This paper shows how energy management system can be effectively implemented by comparing similar generic management elements of energy management to ISO 9000/14000 standards. The seven (7) elements of energy management system discussed are top management commitment, policy establishment, energy management team, energy audit, energy efficiency projects, monitoring and training

    One vital means of raising energy efficiency is to introduce district heating in industry. The aim of this paper is to study factors which promote and inhibit district heating collaborations between industries and utilities. The human factors involved showed to affect district heating collaborations more than anything else does. Particularly risk, imperfect and asymmetric information, credibility and trust, inertia and values are adequate variables when explaining the establishment or failure of industry-energy utility collaborations, while heterogeneity, access to capital and hidden costs appear to be of lower importance. A key conclusion from this study is that in an industry-energy utility collaboration, it is essential to nurture the business relationship. In summary, successful collaboration depends more on the individuals and organizations involved in the relationship between the two parties than on the technology used in the collaboration.

    Risk-based analysis techniques are used to quantify and prioritize a wide variety of problems within the traditional fossil fuel and nuclear power industries. This poster presentation evaluated some of the risk analysis tools and methods used by the energy industry to quantify and manage wind energy development risks. A comprehensive risk-based approach for identifying the probability and consequences of potential concerns was presented for a sample wind energy project. The process determined objectives in relation to the project's net present value. Contributing domains included the energy production, prices, and operating costs of the project. Decision criteria used to evaluate the desirability of the wind project were then developed. Monte Carlo simulations were the used to aggregate individual risks into an overall total. The contribution of each element to the decision objective was calculated separately. The element outputs were than combined into a measure of aggregate risk exposure. Aggregate results were used to calculate the decision criteria. The decision objective was to determine if the energy cost was less than the avoided cost of other project options. The study showed that the approach can allow decision-makers to mitigate risks. However, the results are dependent on the quality of the input data. tabs., figs.

    This publication further develops the analysis presented in the India chapter of Energy Technology Perspectives 2010 and provides insights on the implications of achieving deep energy and CO2 emission cuts in the industrial sector both for India and globally. It investigates the least-cost combination of options that can significantly reduce energy and CO2 emissions in India's industrial sector, while enabling the Indian economy to continue to grow and alleviate energy poverty. For India to play its part in helping to realise deep cuts in global CO2 emissions by the middle of the 21st century, it will need to achieve rapid economic development over the next 40 years with only a very small increase in emissions. Currently there is no precedent for such a low-CO2 development path. The challenge for India will be to achieve strong economic growth while improving energy security, but without locking in high emissions.

    Biomass occurs in abundance in the highly agricultural-based countries of South-East Asia. If these are processed in the wood and agro-processing industries, large volumes of residues are generated. The residue are potential sources of energy which the industries can tap through the use of cogeneration systems, in order to meet their own thermal and electrical requirements. This will reduce the industry's dependence on power from the grid and thus increase their own self-sufficiency in terms of energy. Biomass cogeneration brings the environmental, as well as economic benefits to the industries. It makes use of clean and energy-efficient technologies and utilises biomass as fuels which cause less environment al pollution and the greenhouse effect, as against the use of fossil fuels. A particular mill that embarks on biomass cogeneration is also able to realise, among others, income from the export of excess electricity to the grid. Biomass residue if not used for other purposes have negative values as they need to be disposed of. They can, however, be profit-generating as well. (Author)

    2001-01-01

    Scenarios for a Clean Energy Future (CEF) studied the role that efficient clean energy technologies can play in meeting the economic and environmental challenges for our future energy supply. The study describes a portfolio of policies that would motivate energy users and businesses to invest in innovative energy efficient technologies. On the basis of the portfolios, two policy scenarios have been developed, i.e. a moderate scenario and an advanced scenario. We focus on the industrial part of the CEF-study. The studied policies include a wide scope of activities, which are organized under the umbrella of voluntary industrial sector agreements. The policies for the policy scenarios have been modeled using the National Energy Modeling System (CEF-NEMS). Under the reference scenario industrial energy use would grow to 41 Quads in 2020, compared to 34.8 Quads in 1997, with an average improvement of the energy intensity by 1.1% per year. In the Moderate scenario the annual improvement is a bout 1.5%/year, leading to primary energy use of 37.8 Quads in 2020, resulting in 10% lower CO2 emissions by 2020 compared to the reference scenario. In the Advanced scenario the annual improvement increases to 1.8% per year, leading to primary energy use of 34.3 Quads in 2020, and 29% lower CO2 emissions. We report on the policies, assumptions and results for industry

    Organizations that implement strategic energy management programs have the potential to achieve sustained energy savings if the programs are carried out properly. A key opportunity for achieving energy savings that plant managers can take is to determine an appropriate level of energy performance by comparing their plant's performance with that of similar plants in the same industry. Manufacturing facilities can set energy efficiency targets by using performance-based indicators. The U.S. Environmental Protection Agency (EPA), through its ENERGY STAR{reg_sign} program, has been developing plant energy performance indicators (EPIs) to encourage a variety of U.S. industries to use energy more efficiently. This report describes work with the corn refining industry to provide a plant-level indicator of energy efficiency for facilities that produce a variety of products--including corn starch, corn oil, animal feed, corn sweeteners, and ethanol--for the paper, food, beverage, and other industries in the United States. Consideration is given to the role that performance-based indicators play in motivating change; the steps needed to develop indicators, including interacting with an industry to secure adequate data for an indicator; and the actual application and use of an indicator when complete. How indicators are employed in the EPA's efforts to encourage industries to voluntarily improve their use of energy is discussed as well. The report describes the data and statistical methods used to construct the EPI for corn refining plants. Individual equations are presented, as are the instructions for using them in an associated Excel spreadsheet.
