The economy of refrigerators and airconditioning systems is essentially determined by the rates of the different types of energy. The drives commonly used in refrigerators are electric motors, but some larger systems have gas engines. Apart from the investment cost, therefore, it is above all the the cost of operation or power cost that shows in the books. These costs accrue over the entire service-life of the system and represent current annual costs. (orig.) [German] Die Wirtschaftlichkeit von Kaelte- und Klimaanlagen wird im wesentlichen von den Preisen der verschiedenen Energiearten bestimmt. Ueblicherweise sind Elektromotoren fuer den Antrieb in Kaelteanlagen in Verwendung, die aber bei groesseren Systemen auch durch Gasmotoren ersetzt werden. Neben den Anlagenkosten fuer die Investitionen sind es vor allem die Betriebs- und damit also die Stromkosten, die zu Buche schlagen. Diese fallen ueber die gesamte Betriebszeit bzw. Lebensdauer der Anlage an und sind damit laufende Jahreskosten. (orig.)

The paper presents multicriteria decision aid analysis of the choice of PV installation providing electric energy to a public utility building. From the energy management point of view electricity obtained by solar radiation has become crucial renewable energy source. Application of PV installations may occur a profitable solution from energy, economic and ecologic point of view for both existing and newly erected buildings. Featured variants of PV installations have been assessed by multicriteria analysis based on ANP (Analytic Network Process) method. Technical, economical, energy and environmental criteria have been identified as main decision criteria. Defined set of decision criteria has an open character and can be modified in the dialog process between the decision-maker and the expert - in the present case, an expert in planning of development of energy supply systems. The proposed approach has been used to evaluate three variants of PV installation acceptable for existing educational building located in Poznań, Poland - the building of Faculty of Chemical Technology, Poznań University of Technology. Multi-criteria analysis based on ANP method and the calculation software Super Decisions has proven to be an effective tool for energy planning, leading to the indication of the recommended variant of PV installation in existing and newly erected public buildings. Achieved results show prospects and possibilities of rational renewable energy usage as complex solution to public utility buildings.

The first renewable marine energy projects were first presented during the so called Eole program in 1996, and then during a call for bids on offshore wind-power in 2004. Despite these initiatives and a second call for bids in 2011, only a few prototypes are being tested at the beginning of 2013. This study aims to determine if the French legislation is adapted to this emerging new activity of renewable marine energy installation implementation. The results of three-year research show that several advances have contributed to defining a legal framework favorable to the implementation of renewable marine energy production installation; yet, their legal regime has not been finalized. Nevertheless, a comparison with maritime and coastal legislations reveals solutions are worth considering and possible. As a result, an intervention from legislative or parliamentary authorities seems necessary to simplify the implementation of projects and to limit the risks of legal disputes [fr

A stable supply of energy is critical for sustainable economic development and the ever-increasing demand for energy resources drives the need for alternative weather-driven renewable energy solutions such as solar and wind-generated power. Recognizing the importance of energy as a strategic resource, the Department of the Navy has focused on energy efficient solutions aiming to increase tactical and shore energy security and reduce greenhouse gas emissions. Implementing alternative energy solutions will alleviate the Navy installations demands on the National power grid, however transitioning to renewable energy sources is a complex multi-stage process that involves initial investment in resource assessment and feasibility of building solar and wind power systems in Navy's facilities. This study focuses on the wind and solar energy resource assessment for Navy installations in the Midwestern US. We use the dynamically downscaled datasets at 12 km resolution over the Continental US generated with the Weather Research and Forecasting (WRF) model to derive the wind climatology in terms of wind speed, direction, and wind power at 20 m above the surface for 65 Navy facilities. In addition, we derived the transmissivity of the atmosphere, diffuse radiation fraction, cloud cover and seasonal energy potential for a zenith facing surface with unobstructed horizon for each installation location based on the results of a broadband radiative transfer model and our cloud database based on 17-years of GOES data. Our analysis was incorporated in a GIS framework in combination with additional infrastructure data that enabled a synergistic resource assessment based on the combination of climatological and engineering factors.

A Framework to Survey the Energy Efficiency of Installed Motor Systems

Energy Technology Data Exchange (ETDEWEB)

Rao, Prakash; Hasanbeigi, Ali; McKane, Aimee

2013-08-01

While motors are ubiquitous throughout the globe, there is insufficient data to properly assess their level of energy efficiency across regional boundaries. Furthermore, many of the existing data sets focus on motor efficiency and neglect the connected drive and system. Without a comprehensive survey of the installed motor system base, a baseline energy efficiency of a country or region’s motor systems cannot be developed. The lack of data impedes government agencies, utilities, manufacturers, distributers, and energy managers when identifying where to invest resources to capture potential energy savings, creating programs aimed at reducing electrical energy consumption, or quantifying the impacts of such programs. This paper will outline a data collection framework for use when conducting a survey under a variety of execution models to characterize motor system energy efficiency within a country or region. The framework is intended to standardize the data collected ensuring consistency across independently conducted surveys. Consistency allows for the surveys to be leveraged against each other enabling comparisons to motor system energy efficiencies from other regions. In creating the framework, an analysis of various motor driven systems, including compressed air, pumping, and fan systems, was conducted and relevant parameters characterizing the efficiency of these systems were identified. A database using the framework will enable policymakers and industry to better assess the improvement potential of their installed motor system base particularly with respect to other regions, assisting in efforts to promote improvements to the energy efficiency of motor driven systems.

Energy-saving belt conveyors installed in Polish collieries

Directory of Open Access Journals (Sweden)

Jerzy ANTONIAK

2010-01-01

Full Text Available An important problem of reducing energy consumption and dioxide emissions in the stage of construction and operation of mine belt conveyors is connected with their broad use in the industry. However, this notion is related to a reduction of electric energy consumption for conveyor drive and for production of conveyor components and assemblies (belts, rollers, load-bearing structure etc.. An essential role is played by an increased life of belt conveyors assemblies and components, principally belts. A reduced electric energy consumption results in a decreased CO2 emissions, e.g. hard coal – fired power station issues 0.28 kg CO2 per production of 1 kWh, in to answer production of 1 t steel accounts for 3.2 t CO2 emissions. The subject-matter presented in the paper concerning energy-saving in the horizontally and inclined mine belt conveyors installed in a Polish colliery – Anna, Jankowice and Marcel, has a big economic significance and it is important from the point of view of environmental protection.

In the last few years, the distributed energy production from small wind turbines (i.e.<200 kWp) has developed into a relevant business opportunity for different investors in Italy. The market, especially in Italy, has rapidly grown, achieving 9 MWp only in 2011, with an increase from 1.5 MW in 2009 to 13.3 MW at the end of 2011. This paper reports the results of a case study on the installation of several small wind turbines. It aims to provide an analysis of the conditions in Italy that make it possible to install these machines and offer a reliable reference for designing, planning, and controlling small wind turbine projects while focusing on the strategic variables of time, cost, and quality used by typical enterprises in the investment projects. The results are relevant to investors as well as engineering, procurement, and construction companies involved in this new sector, which must understand Italy’s renewable energy policy and its effects in practice. Moreover, certain national energy policy conclusions are reported and discussed in this paper. To properly study the sector, the data on time, cost and quality are analysed using typical project management tools. - Highlights: • Focus on the Italian wind energy sector. • Analysis of Italian policy effects. • Focus on small/medium size wind energy machines

Tidal Energy Conversion Installation at an Estuarine Bridge Site: Resource Evaluation and Energy Production Estimate

Science.gov (United States)

Wosnik, M.; Gagnon, I.; Baldwin, K.; Bell, E.

2015-12-01

The "Living Bridge" project aims to create a self-diagnosing, self-reporting "smart bridge" powered by a local renewable energy source, tidal energy - transforming Memorial Bridge, a vertical lift bridge over the tidal Piscataqua River connecting Portsmouth, NH and Kittery, ME, into a living laboratory for researchers, engineers, scientists, and the community. The Living Bridge project includes the installation of a tidal turbine at the Memorial Bridge. The energy converted by the turbine will power structural health monitoring, environmental and underwater instrumentation. Utilizing locally available tidal energy can make bridge operation more sustainable, can "harden" transportation infrastructure against prolonged grid outages and can demonstrate a prototype of an "estuarine bridge of the future". A spatio-temporal tidal energy resource assessment was performed using long term bottom-deployed Acoustic Doppler Current Profilers (ADCP) at two locations: near the planned deployment location in 2013-14 for 123 days and mid-channel in 2007 for 35 days. Data were evaluated to determine the amount of available kinetic energy that can be converted into usable electrical energy on the bridge. Changes in available kinetic energy with ebb/flood and spring/neap tidal cycles and electrical energy demand were analyzed. The target deployment site exhibited significantly more energetic ebb tides than flood tides, which can be explained by the local bathymetry of the tidal estuary. A system model is used to calculate the net energy savings using various tidal generator and battery bank configurations. Different resource evaluation methodologies were also analyzed, e.g., using a representative ADCP "bin" vs. a more refined, turbine-geometry-specific methodology, and using static bin height vs. bin height that move w.r.t. the free surface throughout a tidal cycle (representative of a bottom-fixed or floating turbine deployment, respectively). ADCP operating frequencies and bin

AEP studied the direct and indirect benefits, strengths, and weaknesses of distributed energy storage systems (DESS) and chose to transform its entire utility grid into a system that achieves optimal integration of both central and distributed energy assets. To that end, AEP installed the first NAS battery-based, energy storage system in North America. After one year of operation and testing, AEP has concluded that, although the initial costs of DESS are greater than conventional power solutions, the net benefits justify the AEP decision to create a grid of DESS with intelligent monitoring, communications, and control, in order to enable the utility grid of the future. This report details the site selection, construction, benefits and lessons learned of the first installation, at Chemical Station in North Charleston, WV.

The utilization of electron accelerators (eBA) is gradually increased in Thailand. For instance, a 30-40 MeV eBA are used for tumor and cancer therapy in the hospitals, and a high current eBA in for gemstone colonization. In the near future, an application of eBA in industries will be grown up in a few directions, e.g., flue gases treatment from the coal fire-power plants, plastic processing, rubber vulcanization and food preservation. It is the major roles of Office of Atomic Energy for Peace (OAEP) to promote the peaceful uses of nuclear energy and to regulate the public safety and protection of the environment. By taking into account of radiation safety aspect, high energy electrons are not only harmful to human bodies, but the radioactive nuclides can be occurred. This report presents a literature review by following the National Committee on Radiation Protection and Measurements (NCRP) report No.31.

In this report, we fill a gap in the existing knowledge about PV-plus-storage system costs and value by providing detailed component- and system-level installed cost benchmarks for residential systems. We also examine other barriers to increased deployment of PV-plus-storage systems in the residential sector. The results are meant to help technology manufacturers, installers, and other stakeholders identify cost-reduction opportunities and inform decision makers about regulatory, policy, and market characteristics that impede solar plus storage deployment. In addition, our periodic cost benchmarks will document progress in cost reductions over time. To analyze costs for PV-plus-storage systems deployed in the first quarter of 2016, we adapt the National Renewable Energy Laboratory's component- and system-level cost-modeling methods for standalone PV. In general, we attempt to model best-in-class installation techniques and business operations from an installed-cost perspective. In addition to our original analysis, model development, and review of published literature, we derive inputs for our model and validate our draft results via interviews with industry and subject-matter experts. One challenge to analyzing the costs of PV-plus-storage systems is choosing an appropriate cost metric. Unlike standalone PV, energy storage lacks universally accepted cost metrics, such as dollars per watt of installed capacity and lifetime levelized cost of energy. We explain the difficulty of arriving at a standard approach for reporting storage costs and then provide the rationale for using the total installed costs of a standard PV-plus-storage system as our primary metric, rather than using a system-size-normalized metric.

The US Department of Energy (DOE) Office of Environmental Restoration (EM-40) has developed the Relative Ranking Evaluation Framework (RREF) to help categorize release sites, facilities and buildings requiring restoration or decommissioning. Based on this framework, a computer tool, the Relative Rank Evaluation Program (RREP) has been developed to evaluate release sites, facilities and buildings, and to manage information pertaining to relative ranking evaluations. The relative ranking information is being used by both Headquarters and field project managers, and other environmental personnel responsible for planning, executing and evaluation environmental restoration activities at DOE installations. External stakeholders, such as representatives of federal and state regulatory agencies, local governments and communities in the vicinity of current and formerly used DOE installations may use this data to review proposed and planned activities

Unseen influence—The role of low carbon retrofit advisers and installers in the adoption and use of domestic energy technology

International Nuclear Information System (INIS)

Owen, A.; Mitchell, G.; Gouldson, A.

2014-01-01

Reducing climate changing emissions associated with residential property continues to be a significant challenge. Five case studies of different domestic energy technology schemes in England highlight the influence of advisers and installers in householders’ decisions to adopt low carbon technologies. Many of these advisers and installers are micro-enterprises working in connected groups in particular geographic areas. Such micro-enterprises form a large part of the construction sector, but despite the number of enterprises and the potential impact of changes in the behaviour of the sole traders and small firms, there appears to be little policy that specifically targets this group. Data from these case studies is presented and organised into a typological framework, in order to illustrate the range of ways in which the impact of advisers and installers can be modified. Two of the six factors in the typological framework relate to the motivation of installers themselves and how their work is perceived by their clients. By examining these factors in particular, this paper makes a novel contribution to understanding the factors that influence the take up and use of domestic energy technologies, leading to the possibility of new policy options or interventions. - Highlights: • Five UK schemes to promote domestic energy technology are examined. • Advisers and installers influence the impact of energy technology. • Micro-enterprises dominate low carbon retrofit. • Low carbon retrofit installers are beyond the reach of current policy. • A framework for investigating installer competence is proposed

There is a great politically will to expand the green energy market in these times. A proven green technology is wind turbines. Wind turbines have been installed in great numbers on land over the last decades. However, the current development in wind turbine design leads to larger turbine sizes...... in order to reduce the cost of energy. This limits the on land application due to transportation limitations and unwillingness from prospect neighbours. Thus, offshore wind energy started developing over the last couple of years. Although installing the wind turbines offshore resolves the before men tioned...... issues, it brings up the cost of energy mainly due to increased installation and maintenance costs.

Scenario and multiple criteria decision analysis for energy and environmental security of military and industrial installations.

Science.gov (United States)

Karvetski, Christopher W; Lambert, James H; Linkov, Igor

2011-04-01

Military and industrial facilities need secure and reliable power generation. Grid outages can result in cascading infrastructure failures as well as security breaches and should be avoided. Adding redundancy and increasing reliability can require additional environmental, financial, logistical, and other considerations and resources. Uncertain scenarios consisting of emergent environmental conditions, regulatory changes, growth of regional energy demands, and other concerns result in further complications. Decisions on selecting energy alternatives are made on an ad hoc basis. The present work integrates scenario analysis and multiple criteria decision analysis (MCDA) to identify combinations of impactful emergent conditions and to perform a preliminary benefits analysis of energy and environmental security investments for industrial and military installations. Application of a traditional MCDA approach would require significant stakeholder elicitations under multiple uncertain scenarios. The approach proposed in this study develops and iteratively adjusts a scoring function for investment alternatives to find the scenarios with the most significant impacts on installation security. A robust prioritization of investment alternatives can be achieved by integrating stakeholder preferences and focusing modeling and decision-analytical tools on a few key emergent conditions and scenarios. The approach is described and demonstrated for a campus of several dozen interconnected industrial buildings within a major installation. Copyright © 2010 SETAC.

Public street lighting consumes large energy for the public interest, but many street lights still do not use energy-saving technologies. In 2014, Provincial Government of DKI Jakarta operated 179,305 units of street lights. Of the number of installed armature, 92 % of them or 166,441 units are HPS (High-Pressure Sodium) armatures which are inefficient. In 2016, the Provincial Government of DKI Jakarta cut down the energy used for street lighting, by implementing the programs of kWh-meter installation in every street lighting panel and use energy-saving lamps equipped with the smart system. The Provincial Government of DKI Jakarta is registered with 6,399 customer IDs in PLN (State Owned Electric Company), and gradually carried out the kWh Meter installation and changes to the contract. The program to use energy-saving lights done by replacing the HPS armature that is not energy efficient to LED armature which is known to be energy efficient. Until the end of 2016, the number of armatures that has been replaced was 89,417 units. The research results on 25 samples of PLN customer IDs and the replacement of 2,162 units armature, showed that the energy efficiency through kWh meter installation and armature replacement reduce the power consumption from 330,414 kWh to 71,278 kWh or by 78.43%. Generally, there was a decrease in the value of electricity bill compared to the before the replacement. The program of kWh-meter installations and replacement of the armature has a payback period of 2.66 years.

Gagnon, Ian; Baldwin, Ken; Wosnik, Martin

2015-11-01

The ``Living Bridge'' project plans to install a tidal turbine at Memorial Bridge in the Piscataqua River at Portsmouth, NH. A spatio-temporal tidal energy resource assessment was performed using long term bottom-deployed Acoustic Doppler Current Profilers ADCP. Two locations were evaluated: at the planned deployment location and mid-channel. The goal was to determine the amount of available kinetic energy that can be converted into usable electrical energy on the bridge. Changes in available kinetic energy with ebb/flood and spring/neap tidal cycles and electrical energy demand were analyzed. A system model is used to calculate the net energy savings using various tidal generator and battery bank configurations. Differences in the tidal characteristics between the two measurement locations are highlighted. Different resource evaluation methodologies were also analyzed, e.g., using a representative ADCP ``bin'' vs. a more refined, turbine-geometry-specific methodology, and using static bin height vs. bin height that move w.r.t. the free surface throughout a tidal cycle (representative of a bottom-fixed or floating turbine deployment, respectively). ADCP operating frequencies and bin sizes affect the standard deviation of measurements, and measurement uncertainties are evaluated. Supported by NSF-IIP grant 1430260.

Renewable Energy, Authenticity, and Tourism: Social Acceptance of Photovoltaic Installations in a Swiss Alpine Region

Directory of Open Access Journals (Sweden)

Annina Helena Michel

2015-05-01

Full Text Available With the increasing emergence of renewable energy sites in Switzerland, new impacts on the landscape can be observed. Above the Alpine village of Bellwald, a pilot project testing avalanche barriers as a possible site for photovoltaic installations was inaugurated in 2012. This study focused on social aspects of the project and asked questions about local residents' and tourists' perceptions of and attitudes toward the installations. Its findings reveal that the new elements are not perceived as a drastic intrusion into the landscape, because the view was already affected by the avalanche barriers, which are accepted because of their vital protective function. No significant difference was found between residents' and tourists' evaluation of the new photovoltaic installations. However, different factors influenced the perceptions of these 2 groups. In both groups, conceptions related to place played an important role in the evaluation of possible photovoltaic sites.

Field installation versus local integration of photovoltaic systems and their effect on energy evaluation metrics

International Nuclear Information System (INIS)

Halasah, Suleiman A.; Pearlmutter, David; Feuermann, Daniel

2013-01-01

In this study we employ Life-Cycle Assessment to evaluate the energy-related impacts of photovoltaic systems at different scales of integration, in an arid region with especially high solar irradiation. Based on the electrical output and embodied energy of a selection of fixed and tracking systems and including concentrator photovoltaic (CPV) and varying cell technology, we calculate a number of energy evaluation metrics, including the energy payback time (EPBT), energy return factor (ERF), and life-cycle CO 2 emissions offset per unit aperture and land area. Studying these metrics in the context of a regionally limited setting, it was found that utilizing existing infrastructure such as existing building roofs and shade structures does significantly reduce the embodied energy requirements (by 20–40%) and in turn the EPBT of flat-plate PV systems due to the avoidance of energy-intensive balance of systems (BOS) components like foundations. Still, high-efficiency CPV field installations were found to yield the shortest EPBT, the highest ERF and the largest life-cycle CO 2 offsets—under the condition that land availability is not a limitation. A greater life-cycle energy return and carbon offset per unit land area is yielded by locally-integrated non-concentrating systems, despite their lower efficiency per unit module area. - Highlights: ► We evaluate life-cycle energy impacts of PV systems at different scales. ► We calculate the energy payback time, return factor and CO 2 emissions offset. ► Utilizing existing structures significantly improves metrics of flat-plate PV. ► High-efficiency CPV installations yield best return and offset per aperture area. ► Locally-integrated flat-plate systems yield best return and offset per land area.

The use of a low temperature geothermal spring together with the heat energy still contained in waste water from the different therapy systems installed in a spa (shower, jets, bathrooms, jacuzzis, pools, ventilation processes) can significantly reduce the operating and maintenance costs of the installation. This covers part of the air conditioning needs of the building and of the heating of thermal water to the appropriate temperature for therapeutic use. In the first part of the study, an analysis of the spring's situation was made, calculating the thermal water needs and presenting the consumption according to the operation schedule on different types of day. In this way, the contribution the spring was capable of giving was compared and the evolution of the thermal water in the tanks was studied. In the second part, the climatic conditions that the spa should meet are studied, along with the loads that it should support, the energy reclaimed from the different heat focuses and the repercussions on the final solution.

In FY1999, Pacific Northwest National Laboratory conducted an energy efficiency campaign for residential housing at the Fort Lewis Army Installation near Tacoma, Washington. Preliminary weather-corrected calculations show energy savings of 10{percent} from FY98 for energy use in family housing. This exceeded the project's goal of 3{percent}. The work was funded by the U.S. DOEs Federal Energy Management Program (FEMP), Office of Energy Efficiency and Renewable Energy. The project adapted FEMP's national ``You Have the Power Campaign'' at the local level, tailoring it to the military culture. The applied research project was designed to demonstrate the feasibility of tailored, research-based strategies to promote energy conservation in military family housing. In contrast to many energy efficiency efforts, the campaign focused entirely on actions residents could take in their own homes, as opposed to technology or housing upgrades. Behavioral change was targeted because residents do not pay their own utility bills; thus other motivations must drive personal energy conservation. This campaign augments ongoing energy savings from housing upgrades carried out by Fort Lewis. The campaign ran from September 1998 through August 1999. The campaign strategy was developed based on findings from previous research and on input from residents and officials at Fort Lewis. Energy use, corrected to account for weather differences, was compared with the previous year's use. Survey responses from 377 of Fort Lewis residents of occupied housing showed that the campaign was moderately effective in promoting behavior change. Of those who were aware of the campaign, almost all said they were now doing one or more energy-efficient things that they had not done before. Most people were motivated by the desire to do the right thing and to set a good example for their children. They were less motivated by other factors.

It is widespread practice for final consumers to procure their energy supply through the ''private'' installations of third parties, that is, outside the public supply grids. This applies to many industrial sites with their own, historically evolved supply structures but also to airports, office buildings, camping sites and hotels. The regulatory treatment of this category of energy distribution plant is anything but trivial. Until the enactment of the 2011 amendment to the Energy Economy Law (EnWG) these installations were often regarded as object-related networks not amenable to regulation, a position which the European Court of Justice saw as violating European law in some cases. In view of the fact that the successor regulation concerning ''stand-alone distribution networks'' in paragraph 110 EnWG provides little scope for privileges, many today consider the concept of ''customer installation'', which only came under explicit regulation through the 2011 amendment, to be the ideal way to keep these installations clear of regulation. Customer installations do not count as energy distribution plants. One question that yet remains to be defined by law is at what point the regulated grid ends and the customer installation begins. This delimitation is fraught with problems because it touches on many legal concepts requiring interpretation. Another question quite aside from this is whether the legislature might have yet again violated European law through these provisions.

Peak Load Regulation and Cost Optimization for Microgrids by Installing a Heat Storage Tank and a Portable Energy System

Directory of Open Access Journals (Sweden)

Hong Zhang

2018-04-01

Full Text Available With the rapid growth of electricity demands, many traditional distributed networks cannot cover their peak demands, especially in the evening. Additionally, with the interconnection of distributed electrical and thermal grids, system operational flexibility and energy efficiency can be affected as well. Therefore, by adding a portable energy system and a heat storage tank to the traditional distributed system, this paper proposes a newly defined distributed network to deal with the aforementioned problems. Simulation results show that by adding a portable energy system, fossil fuel energy consumption and daily operation cost can be reduced by 8% and 28.29%, respectively. Moreover, system peak load regulating capacity can be significantly improved. However, by introducing the portable energy system to the grid, system uncertainty can be increased to some extent. Therefore, chance constrained programming is proposed to control the system while considering system uncertainty. By applying Particle Swarm Optimization—Monte Carlo to solve the chance constrained programming, results show that power system economy and uncertainty can be compromised by selecting appropriate confidence levels α and β. It is also reported that by installing an extra heat storage tank, combined heat and power energy efficiency can be significantly improved and the installation capacity of the battery can be reduced.

The economic success of offshore wind energy and hence its competitiveness alongside conventional energy generation depends to a major extent on the reliability and availability of the installations. The profitability is determined, as is efficiency, by the costs for operation and maintenance over the whole plant life. Only plants with low operational management costs are therefore attractive in the long-term for the market and will help create customer satisfaction and loyalty. Because the costs for servicing and maintenance of offshore installations will be several times higher than for onshore facilities, the manufacturers and operators are called upon to think about new approaches to monitoring and maintaining offshore wind turbines. (orig.) [German] Der wirtschaftliche Erfolg der Offshore-Windenergie und somit die Konkurrenzfaehigkeit gegenueber konventioneller Energiegewinnung haengt massgeblich von der Zuverlaessigkeit und der Verfuegbarkeit der Anlagen ab. Die Wirtschaftlichkeit wird neben dem Wirkungsgrad durch die Kosten fuer Betrieb und Wartung waehrend der gesamten Anlagenlebensdauer bestimmt. Nur Anlagen mit geringen Betriebsfuehrungskosten sind daher fuer den Markt langfristig attraktiv und tragen zur Kundenzufriedenheit und -bindung bei. Weil die Kosten fuer Wartung und Instandhaltung von Offshore-Anlagen um ein vielfaches hoeher sein werden als bei Onshore-Anlagen, sind die Hersteller und Betreiber aufgefordert, ueber neue Konzepte der Windenergieanlagen-(WEA-)Ueberwachung und -instandhaltung nachzudenken.

Evaluation of Installation Time for SMASHmount by SMASHsolar

Energy Technology Data Exchange (ETDEWEB)

2017-04-05

The Department of Energy SunShot Incubator program provides early-stage assistance to help startup companies cross technological barriers to commercialization while encouraging private sector investment. The SunShot Incubator program aims to shorten the time it takes for a young business or company to develop an innovative product concept and make it commercially available, which includes product prototyping, deployment, and, potentially, manufacturing. SMASHsolar was selected as an Incubator awardee to develop a simple, snap-together, module-integrated photovoltaic (PV) mounting system in attempts to dramatically reduce the time, effort and skill needed to install rooftop solar. In support of this award, the National Renewable Energy Laboratory worked with SMASHsolar to develop a procedure for evaluating the installation time required for the SMASHmount system vs. widely-available rail systems. Amongst several installations, NREL measured the following installation times, subject to the qualifications and conditions described later in this report. NREL found that the SMASHsolar SMASHmount system was installed between 15% and 37% faster than tested competing systems after one or two installations of the system.

Installed capacity in New York

International Nuclear Information System (INIS)

Charlton, J.

2006-01-01

This presentation discussed capacity issues related to the New York Independent System Operator (NYISO). The NYISO's market volume was approximately $11 billion in 2005, and it was responsible for providing 32,075 MW of electricity at peak load to its users. Regulatory uncertainty is currently discouraging investment in new generating resources. All load serving entities are required to contract for sufficient capacity in order to meet their capacity obligations. Market participants currently determine capacity and energy revenues. The NYISO market allows suppliers to recover variable costs for providing ancillary services, and the economic value of the revenue source governs decisions made in the wholesale electricity market. The installed capacity market was designed as a spot auction deficiency auction. Phased-in demand curves are used to modify the installed capacity market's design. A sloped demand curve mechanism is used to value capacity above the minimum requirement for both reliability and competition. Participation in the day-ahead market enhances competition and exerts downward pressure on energy and ancillary service market prices. It was concluded that the market structures and design features of the installed capacity markets recognize the need for system reliability in addition to encouraging robust competition and recognizing energy price caps and regulatory oversights. tabs., figs

Environmental settings for selected U.S. Department of Energy installations - support information for the Programmatic Environmental Impact Statement

This report contains the environmental setting information developed for 20 U.S. Department of Energy (DOE) installations in support of the DOE's Programmatic Environmental Impact Study (PEIS). The objective of the PEIS is to provide the public with information about the types of radiological and hazardous wastes and environmental contamination problems associated with major DOE facilities across the country, and to assess the relative risks that these wastes pose to the public, onsite workers, and the environment. Environmental setting information consists of the site-specific data required to model (using the Multimedia Environmental Pollutant Assessment System) the atmospheric, groundwater, and surface water transport of contaminants within and near the boundaries of the installations. The environmental settings data describes the climate, atmospheric dispersion, hydrogeology, and surface water characteristics of the installations. The number of discrete environmental settings established for each installation was governed by two competing requirements: (1) the risks posed by contaminants released from numerous waste sites were to be modeled as accurately as possible, and (2) the modeling required for numerous release sites and a large number of contaminants had to be completed within the limits imposed by the PEIS schedule. The final product is the result of attempts to balance these competing concerns in a way that minimizes the number of settings per installation in order to meet the project schedule while at the same time providing adequate, if sometimes highly simplified, representations of the different areas within an installation. Environmental settings were developed in conjunction with installation experts in the fields of meteorology, geology, hydrology, and geochemistry. When possible, local experts participated in the initial development, fine tuning, and final review of the PEIS environmental settings

Resolving issues with environmental impact assessment of marine renewable energy installations

Directory of Open Access Journals (Sweden)

Ilya M. D. Maclean

2014-12-01

Full Text Available Growing concerns about climate change and energy security have fueled a rapid increase in the development of marine renewable energy installations (MREIs. The potential ecological consequences of increased use of these devices emphasizes the need for high quality environmental impact assessment (EIA. We demonstrate that these processes are hampered severely, primarily because ambiguities in the legislation and lack of clear implementation guidance are such that they do not ensure robust assessment of the significance of impacts and cumulative effects. We highlight why the regulatory framework leads to conceptual ambiguities and propose changes which, for the most part, do not require major adjustments to standard practice. We emphasize the importance of determining the degree of confidence in impacts to permit the likelihood as well as magnitude of impacts to be quantified and propose ways in which assessment of population-level impacts could be incorporated into the EIA process. Overall, however, we argue that, instead of trying to ascertain which particular developments are responsible for tipping an already heavily degraded marine environment into an undesirable state, emphasis should be placed on better strategic assessment.

Impact of size and distribution of installed PV power in E-W direction on the level in which selected consumers’ energy needs were met

Directory of Open Access Journals (Sweden)

Necka Krzysztof

2018-01-01

Full Text Available The aim of the study was to analyse the energy needs of selected consumers and to select the PV installed capacity in the east and west panels orientation (E-W. The analysis was carried out for two variants. The first concerned the impact of the installation power of a PV source on the contracted power in its symmetric east and west position. The second variant was the result of previous observations and studies of the authors of this paper. Thus, in this variant, the unbalanced power of PV E-W in relation to the S azimuth has been analyzed, taking into account the characteristics of the recipients' needs and the variation of the PV power installed. The analyses show that an increase in meeting the energy demand for two of the tested plants at symmetrical power distribution to the east and west occurred only when the installed power was increased to the level of approx. 1.4-1.6 of the contracted power. However, the power distribution in the E-W direction has a very strong effect on the energy amount that is generated in the power plant and cannot be used due to the lack of demand in the plant.

Results of activities under project Marine Renewables Infrastructure Network for Emerging Energy Technologies (MaRINET) are reported, which led to DEMTE, a database, created on the basis of standardized monitoring of the marine environment during installation, operation and decommissioning of Marine Energy Conversion Systems. Obtained with the consortium partners’ available techniques and equipment, the database shows that such instruments cover all identified marine environmental compartments, despite the lack of underwater vehicles and the reduced skills in using satellite technologies. These weaknesses could be overcome by an accurate planning of equipment, techniques and knowledge sharing. The approach here presented also leads to an effective analysis even in non-marine contexts

Solar Installation Labor Market Analysis

2011-12-01

The potential economic benefits of the growing renewable energy sector have led to increased federal, state, and local investments in solar industries, including federal grants for expanded workforce training for U.S. solar installers. However, there remain gaps in the data required to understand the size and composition of the workforce needed to meet the demand for solar power. Through primary research on the U.S. solar installation employer base, this report seeks to address that gap, improving policymakers and other solar stakeholders understanding of both the evolving needs of these employers and the economic opportunity associated with solar market development. Included are labor market data covering current U.S. employment, expected industry growth, and employer skill preferences for solar installation-related occupations. This study offers an in-depth look at the solar installation sectors. A study published by the Solar Foundation in October 2011 provides a census of labor data across the entire solar value chain.

The safety of nuclear installations

International Nuclear Information System (INIS)

1993-01-01

This Safety Fundamental publication sets out basic objectives, concepts and principles for ensuring safety that can be used both by the IAEA in its international assistance operations and by Member States in their national nuclear programmes. These Safety Fundamentals apply primarily to those nuclear installations in which the stored energy developed in certain situations could potentially results in the release of radioactive material from its designated location with the consequent risk of radiation exposure of people. These principles are applicable to a broad range of nuclear installations, but their detailed application will depend on the particular technology and the risks posed by it. In addition to nuclear power plants, such installations may include: research reactors and facilities, fuel enrichment, manufacturing and reprocessing plants; and certain facilities for radioactive waste treatment and storage

Overview of mixed waste issues at the Department of Energy defense installations

International Nuclear Information System (INIS)

Mezga, L.J.; Eisenhower, B.M.

1988-01-01

Due to the /open quotes/double hazard/close quotes/ associated with these waste materials, the ability to manage these mixed wastes has been somewhat limited. The unavailability of acceptable and proven treatment and/or disposal systems has forced the Department of Energy (DOE) installations to place these materials in storage. The limited capacity of permitted storage areas and the desire to move forward in the overall waste management cycle have placed an increased emphasis on the need to develop treatment/disposal technologies for mixed wastes. Programs have been initiated by contractors who operate the DOE installations to provide the technical basis for selecting technologies to render these wastes nonhazardous through treatment by destroying the hazardous constituent, to separate the hazardous constituents from the radioactive constituents, to treat the wastes and place them in a form that will meet EPA requirements to be classified as nonhazardous, and to provide facilities for the disposal of wastes which cannot be changed into a nonhazardous form. These wastes include a variety of materials such as chlorinated solvents and waste oils contaminated with uranium or fission products, liquid scintillation wastes, and sludges from wastewater treatment plants contaminated with uranium or fission products. By volume, the largest mixed waste streams are the contaminated wastewater treatment sludges. Plans for the management of the major categories of mixed waste are presented below. More detailed information on plans for specific waste streams is presented in the paper

Analysis and Prediction of Energy Production in Concentrating Photovoltaic (CPV Installations

Directory of Open Access Journals (Sweden)

Allen Barnett

2012-03-01

Full Text Available A method for the prediction of Energy Production (EP in Concentrating Photovoltaic (CPV installations is examined in this study. It presents a new method that predicts EP by using Global Horizontal Irradiation (GHI and the Photovoltaic Geographical Information System (PVGIS database, instead of Direct Normal Irradiation (DNI data, which are rarely recorded at most locations. EP at four Spanish CPV installations is analyzed: two are based on silicon solar cells and the other two on multi-junction III-V solar cells. The real EP is compared with the predicted EP. Two methods for EP prediction are presented. In the first preliminary method, a monthly Performance Ratio (PR is used as an arbitrary constant value (75% and an estimation of the DNI. The DNI estimation is obtained from GHI measurements and the PVGIS database. In the second method, a lineal model is proposed for the first time in this paper to obtain the predicted EP from the estimated DNI. This lineal model is the regression line that correlates the real monthly EP and the estimated DNI in 2009. This new method implies that the monthly PR is variable. Using the new method, the difference between the predicted and the real EP values is less than 2% for the annual EP and is in the range of 5.6%–16.1% for the monthly EP. The method that uses the variable monthly PR allows the prediction of the EP with reasonable accuracy. It is therefore possible to predict the CPV EP for any location, using only widely available GHI data and the PVGIS database.

2015-08-01

In case of a calamity in the Netherlands - e.g. a dike breach - parts of the nationwide electric network can fall out. In these occasions it would be useful if decentralised energy sources of the Smart Grid would contribute to balance out the fluctuations of the energy network. Decentralised energy sources include: solar energy, wind energy, combined heat and power, and biogas. In this manner, parts of the built environment - e.g. hospitals - that are in need of a continuous power flow, could be secured of this power. When a calamity happens, information about the Smart Grid is necessary to control the crisis and to ensure a shared view on the energy networks for both the crisis managers and network operators. The current situation of publishing, storing and sharing data of solar energy has been shown a lack of reliability about the current number, physical location, and capacity of installed decentralised photovoltaic (PV) panels in the Netherlands. This study focuses on decentralised solar energy in the form of electricity via PV panels in the Netherlands and addresses this challenge by proposing a new, reliable and up-to-date database. The study reveals the requirements for a registration of the installed base of PV panels in the Netherlands. This new database should serve as a replenishment for the current national voluntary registration, called Production Installation Register of Energy Data Services Netherland (EDSN-PIR), of installed decentralised PV panel installations in the Smart Grid, and provide important information in case of a calamity.

Culture safety is aimed to empower all the personnel to contribute and responsible to the installation safety where they work in. Culture safety is important as there were so many accidents happened due to the little attention given to the safety, take as examples of what happened in Three Mille Island installation (1979) and Chernobyl (1986). These remind us that human factor gives a significant contribution to the failure of operational system which influences the safety. Therefore, as one of institutions which has nuclear installation. National Nuclear Energy Agency must apply the culture safety to guarantee the safety operation of nuclear installation to protect the personnel, community and environment from the hazard of radioactive radiation. Culture safety has two main components. The first component under the management responsibility is a framework needed in an organisation. The second component is the personnel attitude in al/ levels to respond and optimize those framework. (author)

Perspective direction for increasing energy efficiency at that type of transport is the application of regenerative braking. For additional increasing of energy efficiency there were suggested the use of capacitive drive on tires of traction substation. One of the main task is the analysis of energy recovery application  with drive and without it.These analysis demonstrated that the calculation algorithms don’t allow in the full volume to carry out calculations of amount and cost of energy recovery without drive and with it. That is why we see the current interest to this topic. The purpose of work is to create methods of algorithms calculation for definite amount and cost of consumed, redundant and recovery energy of electrified urban transport due to definite regime of motion on wayside. There is algorithm developed, which allow to calculate amount and cost of consumed, redundant and recovery energy of electrified urban transport on wayside during the installation capacitive drive at traction substation. On the basis of developed algorithm for the definite regime of wagon motion of subway there were fulfilled the example of energy recovery amount and its cost calculation, among them with limited energy intensity drive, when there are 4 trains on wayside simultaneously.

DOE's Building Technologies Office works with researchers and industry partners to develop and deploy technologies that can substantially reduce energy consumption in residential and commercial buildings. This report aims to advance BTO’s energy savings, emissions reduction, and other program goals by identifying research and development (R&D), demonstration and deployment, and other non-regulatory initiatives for improving the design and installation of residential central air conditioners (CAC) and central heat pumps (CHP). Improving the adoption of CAC/CHP design and installation best practices has significant potential to reduce equipment costs, improve indoor air quality and comfort, improve system performance, and most importantly, reduce household energy consumption and costs for heating and cooling by addressing a variety of common installation issues.

Certification for Small Wind Turbine Installers: What's the Hang Up?; Preprint

Energy Technology Data Exchange (ETDEWEB)

Oteri, F.; Sinclair, K.

2012-03-01

Several programs have been implemented to support the advancement of a professional, mature small wind industry and to ensure that this industry moves forward in a sustainable direction. The development of a standard for small wind turbine systems and the creation of the Small Wind Certification Council support small wind technology that is reliable and safe. Consumers and incentive programs will ultimately rely on certification to differentiate among systems sold in the U.S. market. Certification of small wind installers is yet another component deemed necessary for this industry to expand. The National Renewable Energy Laboratory, under the guidance and funding support of the U.S. Department of Energy, supported the development of small wind system installer certification provided via the North American Board of Certified Energy Practitioners. However, the small wind community is not supportive of the installer certification. There are currently only nine certified installers in the U.S. pool. This paper provides an overview of the installer certification program and why more small wind turbine installers are not pursuing this certification.

For the future installation of a wind farm in Cameroon, the wind energy potentials of three of Cameroon's coastal cities (Kribi, Douala and Limbe) are assessed using NASA average monthly wind data for 31 years (1983-2013) and compared through Weibull statistics. The Weibull parameters are estimated by the method of maximum likelihood, the mean power densities, the maximum energy carrying wind speeds and the most probable wind speeds are also calculated and compared over these three cities. Finally, the cumulative wind speed distributions over the wet and dry seasons are also analyzed. The results show that the shape and scale parameters for Kribi, Douala and Limbe are 2.9 and 2.8, 3.9 and 1.8 and 3.08 and 2.58, respectively. The mean power densities through Weibull analysis for Kribi, Douala and Limbe are 33.7 W/m2, 8.0 W/m2 and 25.42 W/m2, respectively. Kribi's most probable wind speed and maximum energy carrying wind speed was found to be 2.42 m/s and 3.35 m/s, 2.27 m/s and 3.03 m/s for Limbe and 1.67 m/s and 2.0 m/s for Douala, respectively. Analysis of the wind speed and hence power distribution over the wet and dry seasons shows that in the wet season, August is the windiest month for Douala and Limbe while September is the windiest month for Kribi while in the dry season, March is the windiest month for Douala and Limbe while February is the windiest month for Kribi. In terms of mean power density, most probable wind speed and wind speed carrying maximum energy, Kribi shows to be the best site for the installation of a wind farm. Generally, the wind speeds at all three locations seem quite low, average wind speeds of all the three studied locations fall below 4.0m/s which is far below the cut-in wind speed of many modern wind turbines. However we recommend the use of low cut-in speed wind turbines like the Savonius for stand alone low energy needs.

The present integrated research project conducted by Siemens AG in cooperation with the power supply companies PreussenElektra AG and RWE Energie AG was started in March 1994 and finally concluded in March 1996 after a run time of 25 months. On the strength of their know-how as manufacturers of electrotechnical installations and power plants the cooperating partners were fully equipped to examine the technical and economic conditions relevant to the practical application of superconducting energy storages. The aim of the study was to examine the feasibility and economic efficiency of superconducting magnetic energy storages (SMES) for instantaneous provision of reserve capacities. The SMES is also to provide the power for primary regulation, a function effected by slight throttling of live steam valves in conventional thermal power plants. A basic cost estimation was made for economic assessment purposes. The estimated cost of the first plant (including development costs and component testing) and subsequent (series produced) plants is to serve as a basis for the ensuing decision on prototype construction.

Though rooftop photovoltaic (PV) systems are the fastest growing source of distributed generation, detailed information about where they are located and who their owners are is often known only to installers and utility companies. This lack of detailed information is a barrier to policy and financial assessment of solar energy generation and use. To bridge the described data gap, Oak Ridge National Laboratory (ORNL) was sponsored by the Department of Energy (DOE) Office of Energy Policy and Systems Analysis (EPSA) to create an automated approach for detecting and characterizing buildings with installed solar panels using high-resolution overhead imagery. Additionally, ORNL was tasked with using machine learning techniques to classify parcels on which solar panels were automatically detected in the Washington, DC, and Boston areas as commercial or residential, and then providing a list of recommended variables and modeling techniques that could be combined with these results to identify attributes that motivate the installation of residential solar panels. This technical report describes the methodology, results, and recommendations in greater detail, including lessons learned and future work.

The use of a low temperature geothermal spring together with the heat energy still contained in waste water from the different therapy systems installed in a spa (shower, jets, bathrooms, Jacuzzis, pools, ventilation processes) can significantly reduce the operating and maintenance costs of the installation, covering part of the air conditioning needs of the building and the heating of thermal water to the appropriate temperature for therapeutic use. The object of the present work is to study the possible energy use of two sources of thermal hot water (spring and waste water) by restructuring of the existing spa so that it is more efficient from both a technical and economic point of view. In this first part, hot water needs are calculated and consumption presented according to the operation schedule on different types of day. Comparison is then made with the contribution that the spring is capable of making and the evolution of the thermal water in the tanks is studied. In a second work, energy and economic analyses will be presented. (Author)

Safety of nuclear installations

International Nuclear Information System (INIS)

1991-01-01

In accordance with the Nuclear Energy Act, a Licence may only be issued if the precautions required by the state of the art have been taken to prevent damage resulting from the construction and operation of the installation. The maximum admissible body doses in the area around the installation which must be observed in planning constructional and other technical protective measures to counter accidents in or at a nuclear power station (accident planning values, are established). According to the Radiological Protection Ordinance the Licensing Authority can consider these precautions to have been taken if, in designing the installation against accidents, the applicant has assumed the accidents which, according to the Safety Criteria and Guidelines for Nuclear Power Stations published in the Federal Register by the Federal Minister of the Interior after hearing the competent senior state authorities, must determine the design of a nuclear power station. On the basis of previous experience from safety analysis, assessment and operation of nuclear power stations, the accident guidelines published here define which accidents are determinative for the safety-related design of PWR power stations and what verification -particularly with regard to compliance with the accident planning values of the Radiological Protection Ordinance -must be provided by the applicant.

The decision to raise the levy imposed by the Renewable Energies Law has kindled the discussion as to how the energy turnaround can best be implemented and made affordable in the first place. The search for solutions should be founded on as full a picture of the situation as possible as well as a fact base shared by all. The aspiration and purpose of the German 2020 Energy Turnaround Index created by McKinsey and Company is to create precisely such a fact base. Every 3 months the index gives an update on the status of the energy turnaround based on 15 indicators. The present update additionally takes a closer look at the aspect of economic efficiency, which together with climate and environment protection and security of supply forms the triad of imperatives driving the energy turnaround.

This comprehensive final report for the Swiss Federal Office of Energy (SFOE) takes a look at the 800 kW wind turbine installed in 2001/2002 by the Ursern electricity utility near Andermatt, Switzerland, at a height of 2350 meters above sea level. The original prototype wind turbine contained various components from Swiss industry, such as the generator and the inverter. Because of difficulties (cracks in rotor blades, bankruptcy of the manufacturer, etc.) this installation was replaced by an Enercon 600-kW-wind turbine in 2004. Characteristic features of this turbine, such as is its adaptation for use under turbulent wind conditions at cold locations, are discussed. The results obtained in 2005 made it obvious that the utilisation of wind energy in alpine regions is possible and that the extreme conditions at this location do not significantly affect the efficient and safe operation of such an installation. Together with the presence of a meteorological station in the vicinity, optimal operating conditions prevail at this site for further research projects in connection with icing-up of turbine blades and wind energy. The report describes the installation and de-installation of the first turbine and the installation of the present one. Initial experience gained with the installation and its certification by the 'Naturemade' eco-power programme is discussed, as is future expansion at the site.

Piezometer installation and monitoring procedure: Revision 1

International Nuclear Information System (INIS)

1987-04-01

The Deaf Smith County (Texas) site has been selected by the US Department of Energy as one of three candidate sites for characterization to determine its suitability as a geologic repository for high-level nuclear waste. The installation and monitoring of piezometers has been identified as one of the tasks required during the development of an underground Exploratory Shaft Facility to satisfy specific information needs through a program of in situ testing, instrumentation and monitoring. The scope of piezometer installation and monitoring encompasses the installation of fluid pressure measuring equipment and the subsequent collection, presentation and interpretation of piezometric data from strata surrounding the Exploratory Shaft Facility (ESF) prior to, during and following construction of the ESF, and as part of geohydrologic testing within the ESF. This procedure describes the required instrumentation, equipment, and sequence of activities for piezometer installation in the ESF. The procedure also includes details on the data recording and presentation requirements, personnel responsibilities, test management and quality assurance. 16 refs., 12 figs., 2 tabs

New buildings offer the chance of carrying out measures of rational energy use in a favourable and evonomical way; new houses however, only account for a comparatively small share of the annual energy consumption. The lion share still goes to already existing buildings - mostly to building with bad thermal properties and inefficient heating systems. Energy saving measures promise to be successful from an economic as well as from a business point of view. This book endeavours to make a contribution to this point by giving the answer to the following questions. Which measures can be used for residential buildings without getting technical problems; how much energy can possibly be saved; which degree of profitability can be expected.

This report contains the environmental setting information developed for 25 U.S. Department of Energy (DOE) installations in support of the DOE`s Programmatic Environmental Impact Study (PEIS) and the Baseline Environmental Management Report (BEMR). The common objective of the PEIS and the BEMR is to provide the public with information about the environmental contamination problems associated with major DOE facilities across the country, and to assess the relative risks that radiological and hazardous contaminants pose to the public, onsite workers, and the environment. Environmental setting information consists of the site-specific data required to model (using the Multimedia Environmental Pollutant Assessment System) the atmospheric, groundwater, and surface water transport of contaminants within and near the boundaries of the installations. The environmental settings data describes the climate, atmospheric dispersion, hydrogeology, and surface water characteristics of the installations. The number of discrete environmental settings established for each installation was governed by two competing requirements: (1) the risks posed by contaminants released from numerous waste sites were to be modeled as accurately as possible, and (2) the modeling required for numerous release sites and a large number of contaminants had to be completed within the limits imposed by the PEIS and BEMR schedule. The final product is the result of attempts to balance these competing concerns in a way that minimizes the number of settings per installation in order to meet the project schedule while at the same, time providing adequate, if sometimes highly simplified, representations of the different areas within an installation. Environmental settings were developed in conjunction with installation experts in the fields of meteorology, geology, hydrology, and geochemistry.

Full Text Available In the recent decades, the introduction of a sustainable and green energy infrastructure, and, by this, the reduction of emissions caused by fossil energy generation, has been focused on by industry-oriented nations worldwide. Among the technologies of renewable energy generation, wind energy has the highest deployment rate, due to the high wind resource availability and the high technology maturity reached mainly by the onshore installation of wind turbines. However, the planning and the installation of offshore wind farms are a challenging task, because of harsh weather conditions and limited resource availability. Due to the current practice of decentralised information acquisition by the supply chain partners, we investigate the impact of sharing information on the installation process of offshore wind farms by means of a simulation model. Therefore, relevant information items will be identified in order to improve the installation process.

The European strategy for the coming decades sets specific targets for a sustainable growth, including reaching a 20% share of renewables in final energy consumption till 2020. To achieve this target, a number of initiatives and measures have been in force. Europe, is currently the largest market for PV systems with more than 75% of the annual worldwide installations in 2011. The favourable European policies as well as the Member States’ supporting legislations have resulted in high market growth for photovoltaics. Applying PV technologies however, requires high qualified technicians to install, repair and maintain them. Until today, national markets have been growing faster than the skilled PV installers force can satisfy. The PVTRIN, an Intelligent Energy Europe action, addresses these issues by developing a training and certification scheme for technicians active in the installation and maintenance of small scale PV systems. During the implementation of the action, a market research was conducted in the six participating countries in order to record the stakeholders’ attitudes, perceptions and considerations and to adapt the training methods, tools and materials to the national PV industry requirements and markets’ needs. Indicative results of this analysis as well as the current situation regarding relevant training and certification schemes are presented in this paper. - Highlights: ► Market research in six EU countries on PV professional Training and Certification needs. ► PVTRIN scheme integrates the national legislations and the market's needs. ► The different aspects (technical, institutional, financial) are presented

Physical installation of Pelletron and electron cooling system

International Nuclear Information System (INIS)

Hurh, P.

1997-01-01

Bremsstrahlung of 5 MeV electrons at a loss current of 50 microamp in the acceleration region is estimated to produce X-ray intensities of 7 Rad/sec. Radiation losses due to a misteer or sudden obstruction will of course be much higher still (estimated at 87,500 Rad/hr for a 0.5 mA beam current). It is estimated that 1.8 meters of concrete will be necessary to adequately shield the surrounding building areas at any possible Pelletron installation site. To satisfy our present electron cooling development plan, two Pelletron installations are required, the first at our development lab in the Lab B/NEF Enclosure area and the second at the operational Main Injector service building, MI-30, in the main Injector ring. The same actual Pelletron and electron beam-line components will be used at both locations. The Lab B installation will allow experimentation with actual high energy electron beam to develop the optics necessary for the cooling straight while Main Injector/Recycler commissioning is taking place. The MI-30 installation is obviously the permanent home for the Pelletron when electron cooling becomes operational. Construction plans for both installations will be discussed here

In California there are already 350 MW{sub e} worth of solar thermal energy plants in operation on a more or less commercial basis. In these installations thermal oil in parabolic gutters is heated from 300 C to 400 C. The thermal oil passes its thermal energy on to a water vapour circuit via a heat exchanger. The water vapour circuit can also be heated with natural gas, for instance at night when solar energy is not available. However, as yet no existing plant fulfils all three of the following requirements: its construction should entail the lowest possible investment costs and it should be able to run without solar energy and without an expensive storage system; it should have the greatest possible efficiency, especially at times when solar energy is not available (e.g. at night); at the same time, the solar thermal energy should be harvested at the lowest possible temperature so as to make expensive concentrating equipment superfluous. These seemingly contradictory demands are now met by a new concept involving a combined gas and steam plant whose operation is based on the injection of water into the compressed air rather than on a high excess of air. This water is evaporated by solar thermal energy at temperatures below 170 C according to its partial pressure. [Deutsch] Es gibt bereits ueber 350 MWe solarthermische Anlagen in Kalifornien, die mehr oder weniger kommerziell betrieben werden. Bei diesen Anlagen wird Thermaloel von 300 C auf 400 C in Parabolrinnen erhitzt. In einem Waermetauscher gibt das Thermaloel die Waerme an einen Wasserdampfkreislauf ab, der auch mit Erdgas beheizt werden kann, wenn wie z.B. nachts keine Solarwaerme verfuegbar ist. In einem weiteren Schritt wurde vorgeschlagen, das Wasser direkt zu verdampfen. Keine dieser Anlagen genuegt jedoch gleichzeitig den folgenden drei Anforderungen: Die Anlage sollte mit moeglichst niedrigen Investitionskosten gebaut und auch ohne Solarwaerme bzw. ohne aufwendigen Speicher betrieben werden koennen

Installing Omeka

Full Text Available Omeka.net is a useful service for Omeka beginners, but there are a few reasons why you might want to install your own copy of Omeka. Reasons include: * Upgrades. By installing Omeka yourself, you can use the latest versions of Omeka as soon as they’re released, without having to wait for Omeka.net to upgrade their system. * Plugins and themes. You can install any plugin or theme you want, without being restricted to those provided by Omeka.net. * Customizations. You can buy a custom domain name, and customize your code to achieve your desired functionality. * Control. You have control over your own backups, and you can update the server yourself so that its security is always up-to-date. * Price. There are many low-cost Virtual Private Servers (VPSs now, some of which cost only $5 per month. * Storage. Many shared hosting providers now offer unlimited storage. This is useful if you have a large media library. In this tutorial, we’ll be entering a few commands on the command line. This tutorial assumes no prior knowledge of the command line, but if you want a concise primer, consult the Programming Historian introduction to BASH. There are other ways of installing Omeka, of course, some using exclusively GUI tools. Some hosting providers even offer “one-click installs” via their control panels. Many of those methods, however, will install older versions of Omeka which are then harder to upgrade and maintain. The method outlined below may not be the easiest way to install Omeka, but it will give you some good practice with using the command line, which is a skill that will be useful if you want to manually upgrade your install, or manually install other web frameworks. (For example, this installation method is very similar to WordPress’s “Five-Minute Install”. There are four steps to this process, and it should take about an hour.

Measurements of image characteristics of DSA installations

Busch, H.P.; Strauss, L.G.; Freimarck, R.D.

1984-01-01

Measurements for quantifying the image characteristics were carried out on three DSA installations (DVI 1 - Philips, Angiotron - Siemens and DF 3000 - General Eletric). Contrast resolution was measured with a vessel phantom (General Electric) and spatial resolution with a lead grid. A further parameter was the dose entering the image intensifier. The Angiotron was used with an intensifier with 53 cm. diameter and the DF 3000 with temporal subtraction of the video images and the subtraction of dual energy images (hybrid technique). These measurements can be carried out quickly and easily and are a step towards standardisation of measurements of image characteristics of DSA installations. (orig.) [de

electricity, heat and transport demands, and including renewable energy, power plants, and combined heat and power production (CHP) for district heating. Using the 2007 energy system the wind power share is increased by two energy storage options: Pumped Hydro and Heat Pumps in combination with Heat Storages....... The results show that such options can enable an increased penetration of wind power. Using pumped hydro storage (PHS) may increase wind power penetration from 0.5 TWh, for existing PHS installations and up to 6 TWh for very large installations. Using large heat pumps and heat storages in combination...... with specific regulation of power system could additionally increase wind penetration for 0.37 TWh. Hence, with the current technologies installed in the Croatian energy system the installed pumped hydro- plant may facilitate more than 10% wind power in the electricity system.

Worldwide electric energy production data are easy to compile, according to the informations given by individual countries. On the contrary, thermal applications of geothermics are difficult to quantify due to the variety of applications and the number of countries concerned. Exhaustive informations sometimes cannot be obtained from huge countries (China, Russia..) because of data centralization problems or not exploitable data transmission. Therefore, installed power data for geothermal heat production are given for 26 countries over the 57 that have answered the International Geothermal Association questionnaire.

Installation of a Roof Mounted Photovoltaic System

Science.gov (United States)

Lam, M.

2015-12-01

In order to create a safe and comfortable environment for students to learn, a lot of electricity, which is generated from coal fired power plants, is used. Therefore, ISF Academy, a school in Hong Kong with approximately 1,500 students, will be installing a rooftop photovoltaic (PV) system with 302 solar panels. Not only will these panels be used to power a classroom, they will also serve as an educational opportunity for students to learn about the importance of renewable energy technology and its uses. There were four different options for the installation of the solar panels, and the final choice was made based on the loading capacity of the roof, considering the fact that overstressing the roof could prove to be a safety hazard. Moreover, due to consideration of the risk of typhoons in Hong Kong, the solar panel PV system will include concrete plinths as counterweights - but not so much that the roof would be severely overstressed. During and after the installation of the PV system, students involved would be able to do multiple calculations, such as determining the reduction of the school's carbon footprint. This can allow students to learn about the impact renewable energy can have on the environment. Another project students can participate in includes measuring the efficiency of the solar panels and how much power can be produced per year, which in turn can help with calculate the amount of money saved per year and when we will achieve economic parity. In short, the installation of the roof mounted PV system will not only be able to help save money for the school but also provide learning opportunities for students studying at the ISF Academy.

An analysis of inhabitants opinion on energy issues. Comparison between localities of nuclear installation sites and of urban communities

International Nuclear Information System (INIS)

Takahashi, Reiko; Nakagome, Yoshihiro

2004-01-01

For the purpose of comparing the mental attitudes toward nuclear power generation held by the public between localities containing nuclear installation sites and those of urban communities, a survey has been conducted by mail and by direct interviews. The survey conversed Fukushima, Niigata and Fukui Prefectures, representing the former group of localities, whereas Tokyo and Osaka, representing the latter. The mail survey revealed differences between the two groups of localities in their image of power and in their perception of its present status, as well as in their sense of values in daily life. The interview survey indicated that the factors behind the differences included regional characteristics such as temperaments of resident population, and effects on the private life style brought by nuclear installation. Narrowing down this gap of mental attitude between the two groups of localities should call indispensably for better mutual understanding. In bringing this about, consideration should be given to particular local characteristics, including popular mentality and personal view of life, as well as image and knowledge of energy sources held by the individuals.

While the installation of the general services is now almost finished (see presentation by Katy Foraz and Serge Grillot), several problems and delays with the QRL made it unavoidable to revise the installation strategy and to schedule a number tasks in parallel. A new compressed installation planning has been issued, that fulfils the strategic objectives and allows starting new activities with minimal delays in sectors 7-8 and 8-1. However, the shortcuts that are introduced increase the level of risk that we will have to face and the coordination of such a large and complex variety of simultaneous activities makes the project even more challenging. The document will describe how the input from the different equipment groups is taken into account by the master schedule planning team with respect to equipment availability and production as well as logistics...

The Guidebook serves as a handbook for the entire operational sequence, which is necessary for the establishment of a wood combustion plant in Germany with an installed capacity larger than 100 kW{sub th}, for the use of fuel woods such as forest chips, wood and forest residues, pellets, wood waste, etc. within the limits of the laws and regulations prescribed for the respective performance classes. The Guidebook's purpose is to give potential investors and operators of wood combustion plants as well as the appropriate authorities a quick and global overview of the energetic use of wood in order to contribute to an increased application of this technology. The Guidebook introduces a Quality Model in Chapters 2 and 3, which describes the establishment of a wood combustion system in six phases. Eleven Management Aspects are differentiated, which can be helpful during the conversion of a project. Thus, potential investors and operators of wood combustion plants become acquainted with the most important aspects of this kind of project conversion. In addition, Chapter 4 provides an overview of the operating costs of wood combustion plants. The relevant licensing and planning procedures depending on the installed capacity and fuelwood use are comprehensively described in Chapter 5. Chapter 6 supplies a concrete overview of the environmental aspects and emissions of wood combustion. Since wood combustion plants must be - as all other investments - financially secured Chapter 7 provides a description of the relevant information on public means and subsidies. Besides all important promotion programmes, the new German Renewable Energy Law (Erneuerbare-Energien-Gesetz - EEG) of April 2000 is described in detail. Many examples of already realised wood combustion plant projects are described in Chapter 8. As an additional service, all significant addresses from ministries to energy agencies and associations are listed in Chapter 9. (orig.)

This final report for the Swiss Federal Office of Energy (SFOE) presents the results of a study made on large-scale heat pumps, which, although not very common in Switzerland, represent an important energy-potential. The detail measurements on ten installations were made after it was noted that such installations tend to exhibit low performance figures. The seven factors investigated in detail included those causing losses in distribution, hot water preparation as well as source-side factors. Secondary systems-factors such as pumps and hydraulics on the primary and secondary sides are discussed. The importance of further research and quality-control aspects for future implementation of such large-scale heat-pump systems is stressed. Also, energy-economics and emissions-related topics are discussed.

Ramirez Riquelme, Angelica Beatriz

1997-01-01

The development of a licensing system for primary category radioactive installations is described, which aims to satisfy the needs of the Chilean Nuclear Energy Commission's Department of Nuclear and Radiological Safety, particularly the sections for Licensing Outside Radioactive Installations and Safety Control. This system involves the identification, control and inspection of the installations, their personnel and connected activities, for the purpose of protecting the population's health and the environment. Following the basic cycle methodology, a systems analysis and engineering stage was prepared, establishing the functions of the system's elements and defining the requirements, based on interviews with the users. This stage was followed by the design stage, focusing on the data structure, the software architecture and the procedural detail. The codification stage followed, which translated the design into legible machine-readable format. In the testing stage, the entries that were defined were proven to produce the expected data. Finally and operational and maintenance stage was developed, when the system was installed and put to use. All the above generated a useful system for the Licensing section of the Department of Nuclear and Radiological Safety, since it provides faster and easier access to information. A project is described that introduces new development tools in the Computer department following standards established by the C.CH.E.N. (author)

Using the 2007 energy system the wind power share is increased by two energy storage options: Pumped hydro and heat pumps in combination with heat storages....... The results show that such options can enable an increased penetration of wind power. Using pumped hydro storage (PHS) may increase wind power penetration from 0.5 TWh, for existing PHS installations and up to 6 TWh for very large installations. Using large heat pumps and heat storages in combination...... with specific regulation of power system could additionally increase wind penetration for 0.37 TWh. Hence, with the current technologies installed in the Croatian energy system the installed pumped hydro-plant may facilitate more than 10% wind power in the electricity system.

Energy efficiency improvement and ecological safety of heat power plants are urgent problems, which require scientifically grounded approaches and solutions. These problems can be solved partly within the presented heat-and-power cycles by including contact energy exchange equipment in the circuits of existing installations. A significant positive effect is obtained in the contact energy exchange installations, such as gas-steam installation `Aquarius' and the contact hydrogen heat generator that also can use hydrogen as a fuel. In these plants, the efficiency increases approximately by 10-12% in comparison with traditional installations, and the concentration of toxic substances, such as nitrogen oxides and carbon monoxide in flue gas can be reduced to 30 mg/m3 and to 5 mg/m3, respectively. Moreover, the plants additionally `generate' the clean water, which can be used for technical purposes.

2016-03-01

After having indicated locations of French nuclear installations which are currently being dismantled (about 30 installations), and recalled the different categories of radioactive wastes with respect to their activity level and the associated storage options, this article gives an overview of various aspects of dismantling, more precisely in the case of installations owned and managed by the CEA. These operations comprise the dismantling itself, the recovery and packaging of wastes, old effluents and spent fuels. The organisation and responsible departments within the CEA are presented, and the author outlines some operational problematic issues met due to the age of installations (traceability of activities, regulation evolutions). The issue of financing is then discussed, and its uncertainties are outlined. The dismantling strategy within the CEA-DEN is described, with reference to legal and regulatory frameworks. The next parts of the article address the organisation and the economic impact of these decontamination and dismantling activities within the CEA-DEN, highlight how R and D and advanced technology are a support to this activities as R and D actions address all scientific and technical fields of nuclear decontamination and dismantling. An overview of three important dismantling works is proposed: Fontenay-aux-Roses, the Marcoule CEA centre (a reference centre in the field of nuclear dismantling and decontamination) and the Grenoble CEA centre (reconversion in R and D activities in the fields of technologies of information, of communication, technologies, for health, and in renewable energies). The last part addresses the participation to the Strategic Committee of the Nuclear Sector (CSFN)

Reliability and energy efficiency of zero energy homes (Conference Presentation)

Science.gov (United States)

Dhere, Neelkanth G.

2016-09-01

Photovoltaic (PV) modules and systems are being installed increasingly on residential homes to increase the proportion of renewable energy in the energy mix. The ultimate goal is to attain sustainability without subsidy. The prices of PV modules and systems have declined substantially during the recent years. They will be reduced further to reach grid parity. Additionally the total consumed energy must be reduced by making the homes more energy efficient. FSEC/UCF Researchers have carried out research on development of PV cells and systems and on reducing the energy consumption in homes and by small businesses. Additionally, they have provided guidance on PV module and system installation and to make the homes energy efficient. The produced energy is fed into the utility grid and the consumed energy is obtained from the utility grid, thus the grid is assisting in the storage. Currently the State of Florida permits net metering leading to equal charge for the produced and consumed electricity. This paper describes the installation of 5.29 KW crystalline silicon PV system on a south-facing tilt at approximately latitude tilt on a single-story, three-bedroom house. It also describes the computer program on Building Energy Efficiency and the processes that were employed for reducing the energy consumption of the house by improving the insulation, air circulation and windows, etc. Finally it describes actual consumption and production of electricity and the installation of additional crystalline silicon PV modules and balance of system to make it a zero energy home.

Fernández-Pacheco, D.G.; Molina-Martínez, J.M.; Ruiz-Canales, A.; Jiménez, M.

2012-01-01

Highlights: ► Portable and easy-to-use solution to detect possible failures at a PV installation. ► Calculation of solar and photovoltaic parameters by using a mobile device with GPS. ► No software which confers this utility to a mobile device can be found in the market. - Abstract: The application of the Information and Communication Technologies (ICTs) to the photovoltaic (PV) energy sector has increased notably in the last years. This paper presents a new mobile software application for maintenance tasks in PV installations by determining the PV output power of the system, the daily energy production, the clear-sky global solar radiation and other parameters associated with solar position from Global Position Data in handheld devices endowed with Android or Windows Mobile operating systems. The calculation of these parameters permits a technician to know if the PV plant is working properly, since the difference between the PV output power supplied by the installation in a clear-sky day for a determined hourly period and the values estimated by the application should be minimal. In case of fixed installations, the application also permits to determine if the PV module support structures of the installation are correctly oriented. Some comparisons between data supplied by four real PV installations and data calculated by the proposed application were performed for evaluation purposes.

2017-01-01

Highlights: • A multi-objective optimization model for building envelope retrofit is presented. • Facility performance degradation and maintenance is built into the model. • A rooftop PV system is introduced to produce electricity. • Economic factors including net present value and payback period are considered. - Abstract: Retrofitting existing buildings with energy-efficient facilities is an effective method to improve their energy efficiency, especially for old buildings. A multi-objective optimization model for building envelope retrofitting is presented. Envelope components including windows, external walls and roofs are considered to be retrofitted. Installation of a rooftop solar panel system is also taken into consideration in this study. Rooftop solar panels are modeled with their degradation and a maintenance scheme is studied for sustainability of energy and its long-term effect on the retrofitting plan. The purpose is to make the best use of financial investment to maximize energy savings and economic benefits. In particular, net present value, the payback period and energy savings are taken as the main performance indicators of the retrofitting plan. The multi-objective optimization problem is formulated as a non-linear integer programming problem and solved by a weighted sum method. Results of applying the designed retrofitting plan to a 50-year-old building consisting of 66 apartments demonstrated the effectiveness of the proposed model.

Resource Sharing in the Logistics of the Offshore Wind Farm Installation Process based on a Simulation Study

Directory of Open Access Journals (Sweden)

Thies Beinke

2017-06-01

Full Text Available This present contribution examines by means of a discrete event and agent-based simulation the potential of a joint use of resources in the installation phase of offshore wind energy. To this end, wind farm projects to be installed simultaneously are being examined, the impact of weather restrictions on the processes of loading, transport and installation are also taken into consideration, and both the wind farm specific resource allocation and the approach of a resource pool or resource sharing, respectively, are being implemented. This study is motivated by the large number of wind farms that will be installed in the future and by the potential savings that might be realized through resource sharing. While, so far, the main driver of the resource sharing approach has been the end consumer market, it has been applied in more and more areas, even in relatively conservative industries such as logistics. After the presentation of the backgrounds and of the underlying methodology, and the description of the prior art in this context, the network of the offshore wind energy installation phase will be described. This is the basis for the subsequent determination of the savings potential of a shared resource utilization, which is determined by the performance indicators such as the total installation time and degree of utilization of the resources. The results of the simulation show that weather restrictions have a significant effect on the installation times and the usage times of the resources as well as on their degree of utilization. In addition, the resource sharing approach, has been identified to have significant savings potential for the offshore wind energy installation.

The acceleration of nuclear power programmes in OECD Member countries is reflected in the emphasis given by OECD/NEA to its activities in nuclear safety and regulatory matters. Particular effort is devoted to work on radiation protection and radioactive waste management, safety of nuclear installations and nuclear law development. A Committee on the Safety of Nuclear Installations reviews the state of the art and identifies areas for research and co-ordination of national programmes. A Sub-Committee on Licensing collates information and data on licensing standards and practices of different countries with a view to considering problems of common interest. Comparative studies of various licensing systems and discussions between licensing authorities should help to improve regulatory control of nuclear installations for which there appears to be a need for internationally accepted standards in the long run.

Capping off installation

CERN Multimedia

2006-01-01

Installation of the cathode strip chambers for the muon system on the CMS positive endcap has been completed. Technicians install one of the last muon system cathode strip chambers on the CMS positive endcap. Like successfully putting together the pieces of a giant puzzle, installation of the muon system cathode strip chambers on one of the CMS endcaps has been completed. Total installation of the cathode strip chambers (CSC) is now 91 percent complete; only one ring of chambers needs to be mounted on the remaining endcap to finish installation of the entire system. To guarantee a good fit for the 468 total endcap muon system CSCs, physicists and engineers from the collaboration spent about 10 years carefully planning the design. The endcap muon system's cables, boxes, pipes and other parts were designed and integrated using a 3D computerized model. 'It took a long time to do all the computer modelling, but in the long run it saved us an enormous amount of time because it meant that everything fit together,...

Piatti, A.; Piemonte, C.; Rampini, E.; Vatrano, F.; Techint SpA, Milan; ENEA, Rome

1992-01-01

This paper surveyed the natural gas distribution systems employed in the Italian civil, industrial and thermoelectric sectors to identify those installations which can make use of gas decompression energy recovery systems (consisting of turbo-expanders or alternative expanders) to economically generate electric power. Estimates were then made of the total amount of potential energy savings. The study considered as eligible for energy savings interventions only those plants with a greater than 5,000 standard cubic meter per hour plant capacity. It was evaluated that, with suitable decompression equipment installed at 50 key installations (33 civil, 15 industrial), about 200 GWh of power could be produced annually, representing potential savings of about 22,000 petroleum equivalent tonnes of energy. A comparative analysis was done on three investment alternatives involving inputs of varying amounts of Government financial assistance

Legislative provisions governing installations for the disposal of radioactive waste in Spain

1978-01-01

Together with the other installations defined as nuclear or radioactive in the Law on Nuclear Energy of 1964, the construction and operation of nuclear waste facilities are subject to the prior authorisation of the Minister of Industry and Energy. They are also subject to the regulations applicable to mining activities. However, for the moment there exist no criteria regulating the underground disposal of radioactive waste, although it is generally agreed that responsibility for such disposal should be given to a public body, for instance the Junta de Energia Nuclear. Moreover, it is this body which is in charge of the sole existing installation in Spain for the storage of solid radioactive waste. (NEA) [fr

2011-02-01

EERE's Solar Energy Technologies Program is charged with leading the Secretary's SunShot Initiative to reduce the cost of electricity from solar by 75% to be cost competitive with conventional energy sources without subsidy by the end of the decade. As part of this Initiative, the program has funded the National Renewable Energy Laboratory (NREL) to develop module manufacturing and solar PV system installation cost models to ensure that the program's cost reduction targets are carefully aligned with current and near term industry costs. The NREL cost analysis team has leveraged the laboratories' extensive experience in the areas of project finance and deployment, as well as industry partnerships, to develop cost models that mirror the project cost analysis tools used by project managers at leading U.S. installers. The cost models are constructed through a "bottoms-up" assessment of each major cost element, beginning with the system's bill of materials, labor requirements (type and hours) by component, site-specific charges, and soft costs. In addition to the relevant engineering, procurement, and construction costs, the models also consider all relevant costs to an installer, including labor burdens and overhead rates, supply chain costs, and overhead and materials inventory costs, and assume market-specific profits.

The efficiency of a combined power/heat plant is treated in an example relating to a gas turbine. An important prior condition for optimum planning of a combined power/heat plant is assessment of the current position in addition to a demand analysis. Constituting a vital planning instrument for the process are systematic annual continuous curves in respect of electricity and heat. Aided by a PC software program it is possible, on the basis of a few key figures, to establish whether a detailed study is able to bring about any economical solution. In addition, a primary-energy and emission balance-sheet is compiled illustrating the advantages to be gained from combined power/heat systems of relevance to the environment. A sensitivity analysis shows main influential factors exercised on the efficiency of the gas turbine project. As might be expected, the greatest influenc eon profitability comes from the electricity proceeds, the price of fuel and capital costs. Finally, different financing models for combined power/heat plants are discussed along with a price safeguarding method. (orig.)

In this work we present an economic assessment photovoltaic systems using single axis and dual axis solar trackers. The analysis was carried out for the city of Sao Paulo and the results show that in comparison with fixed installations, the single axis system and the dual axis system produce respectively 19.6% and 24.7% more power. The power output of the dual axis system is 4.3% greater than the power output of the single axis system. Considering an annual discount rate of 12% and the equipment cost, the cost of the surplus energy due to the use of the single axis and the dual axis trackers was R$0.25/kWh and R$0.18/kWh. Because the average cost of electricity produced by photovoltaic modules is R$3/kWh, we recommend the installation of solar trackers. (author)

Update on Geothermal Direct-Use Installations in the United States

Energy Technology Data Exchange (ETDEWEB)

Beckers, Koenraad J [National Renewable Energy Laboratory (NREL), Golden, CO (United States); Young, Katherine R [National Renewable Energy Laboratory (NREL), Golden, CO (United States); Snyder, Diana M. [Georgia State University

Direct-use of geothermal energy currently has limited penetration in the United States, with an estimated installed capacity of about 500 MWth, supplying on the order of 0.01% of the total annual U.S. heat demand (about 30 EJ). We see higher penetration levels in other countries such as Iceland (about 90%) and Hungary (2.5%). An updated database of geothermal direct-use systems in the U.S. has been compiled and analyzed, building upon the Oregon Institute of Technology (OIT) Geo-Heat Center direct-use database. Types of directuse applications examined include hot springs resorts and pools, aquaculture farms, greenhouses, and district heating systems, among others; power-generating facilities and ground-source heat pumps were excluded. Where possible, the current operation status, open and close dates, well data, and other technical data were obtained for each entry. The database contains 545 installations, of which 407 are open, 108 are closed, and 30 have an unknown status. Spas are the most common type of installation, accounting for 50% of installations by number. Aquaculture installations (46 out of 407 open installations) account for the largest percentage (26%) of installed capacity in operation (129 MWth out of 501 MWth). Historical deployment curves show the installed capacity significantly increased in the 1970s and 1980s mainly due to development of geothermal district heating, aquaculture, and greenhouse systems. Since the 2000s, geothermal direct-use development appears to have slowed, and the number of sites in operation decreased due to closures. Case studies reveal multiple barriers to geothermal direct-use implementation and operation, including 1) existence of an information gap among stakeholders, developers, and the general public, 2) competition from cheap natural gas, and 3) the family-owned, small-scale nature of businesses might result in discontinuation among generations.

A newly developed high-resolution elastic recoil detection analysis (HERDA) system installed at the 1 MV Tandetron in UTTAC at the University of Tsukuba is introduced. The effective solid angle of detector, energy resolution and detection limit for hydrogen are, for the first time, determined quantitatively by the measurements on an a-C:H (and D) film deposited on a Si substrate. In the case of a 500 keV {sup 16}O{sup +} as the incident beam, an energy resolution of ∼0.45 keV and a detection limit of ∼3.8 × 10{sup 20} atoms/cm{sup 3} (∼0.18 at.%) with a data acquisition time of ∼310 s are derived.

Use of Natural Light vs. Cold LED Lighting in Installations for the Recovery of Victims of Gender Violence: Impact on Energy Consumption and Victims’ Recovery

2017-04-01

Full Text Available The efficiency of lighting installations is a major challenge concerning Governments, productive sectors and individuals. However, the importance of accurate lighting in some areas, especially those related to Health and Wellbeing is so critical that the constraints of energy efficiency and sustainability are not always a priority. This situation has become more critical with the current boom in the application of non-visual effects of light to these areas. In this study, the effects oftwo different kinds of lighting on femalevictims of gender violence are compared and analyzed in terms of positive results and impact on energy consumption and sustainability. The lighting technologies used are integrated in facilities where these women carry out different activities aimed at their integration into daily life after their traumatic experiences. The results are expected to become a tool for professionals working with these collectives and for installation designers. In spite of the well-known effects of cold light, especially for tasks involving arousal, sleepiness and other critical variables, it is demonstrated that daylight, which is obviously cheaper from productive and environmental perspectives, is better for this application.

Briggs, R.; Daniels, A.; Greenaway, R.; Oster, J., Jr.; Racki, D.; Stoeltzing, R.

1982-11-01

Since installation expenses constitute a substantial portion of the cost of a large photovoltaic power system, methods for reduction of these costs were investigated. The installation of the photovoltaic arrays includes all areas, starting with site preparation (i.e., trenching, wiring, drainage, foundation installation, lightning protection, grounding and installation of the panel) and concluding with the termination of the bus at the power conditioner building. To identify the optimum combination of standard installation procedures and automated/mechanized techniques, the installation process was investigated including the equipment and hardware available, the photovoltaic array structure systems and interfaces, and the array field and site characteristics. Preliminary designs of hardware for both the standard installation method, the automated/mechanized method, and a mix of standard installation procedures and mechanized procedures were identified to determine which process effectively reduced installation costs. In addition, costs associated with each type of installation method and with the design, development and fabrication of new installation hardware were generated.

A description is given of a process for automatically analysing separate signal processing channels in real time, one channel per signal, in a facility with significant background noise in signals varying in time and coming from transducers at selected points for the continuous monitoring of the operating conditions of the various components of the installation. The signals are intended to determine potential breakdowns, determine conclusions as to the severity of these potential breakdowns and indicate to an operator the measures to be taken in consequence. The feature of this process is that it comprises the automatic and successive selection of each channel for the purpose of spectral analysis, the automatic processing of the signal of each selected channel to show energy spectrum density data at pre-determined frequencies, the automatic comparison of the energy spectrum density data of each channel with pre-determined sets of limits varying with the frequency, and the automatic indication to the operator of the condition of the various components of the installation associated to each channel and the measures to be taken depending on the set of limits [fr

Border installations cover all nuclear plants located near the border with a neighbouring state. However, the actual distance depends on the context. The distance can vary considerably. Also the prohibition on siting near a heavily populated area also defines the actual distance variably. The distance criteria may be modified by other factors of topography, prevailing climate and so on. Various examples which illustrate the problems are given. For example, the Creys-Melville nuclear power plant is 80km from Geneva and the Cattonam installation is 12km from the French border with Luxembourg and Germany. The Cattenom case is explained and the legal position within the European Institutions is discussed. The French licensing procedures for nuclear power stations are described with special reference to the Cattenom power plant. Border installations are discussed in the context of European Community Law and Public International Law. (U.K.)

This paper examines solar energy development in Malaysia, particularly in relation to the installation of solar Photovoltaic (PV) in residential houses. It analyzes the past activities related to solar energy in Malaysia, in terms of research and developments (R and Ds), the implementations used as well as the national policies for the past 20 years which have pushed the installation of PV in the country. The Feed-In Tariff (FiT) scheme is discussed, showing comparative cost-benefit analysis between the PV installation in houses in the United Kingdom (UK) and Malaysia, and with other investment schemes available in Malaysia. To investigate the awareness of renewable energy policies and incentives, a preliminary survey of the public opinion in Malaysia has been carried out, and an evaluation of public willingness to invest in the FiT scheme by installing the PV on their houses is presented. The cost-benefit analysis shows that the proposed FiT programme is capable of generating good return on investment as compared to the one in the UK, but the return is lower than other investment tools. The survey suggests that most Malaysians are unaware of the government’s incentives and policies towards renewable energies, and are not willing to invest in the FiT scheme. - Highlights: ► Past activities related to solar energy is evaluated and FIT scheme is discussed. ► Financial analysis is presented; public perspective is evaluated. ► The FIT scheme generates higher return for PV installation in Malaysia than in the UK. ► The scheme, however, produces lower return than most investment schemes. ► Malaysians’ awareness levels are low and are not willing to invest in the FIT scheme.

The main characteristics, basic circuit and configuration of equipment of the VG-400 atomic power and technological installation are considered. This installation is intended for supplying with highly-potential heat of thermal electrochemical hydrogen production and for power generation in the steam-turbine cycle. The main installation characteristics: HTGR reactor heat power 1100 MW, electric power 300 MW, helium coolant pressure 50 atm, output temperature 950 deg C, steam pressure in the second contour 175 atm, temperature 535 deg C, core diameter and height 6.4 m and 4 m, respectively, number of spherical fuel elements 8.5x10 5 . The installation can ensure hydrogen production of 10 5 Nxm 3 /h. For the VG-400 reactor block the integral arrangement of the first circuit equipment in the reinforced concrete is chosen. Two versions of the reactor core with prismatic and spherical fuel elements are compared. It is shown that taking into account great potentialities of the spherical zone in a case of further temperature increase and its positive qualities with respect to construction and processing of fuel elements and graphite blocks, the utilization of simplier units and mechanisms in the overloading system and in the process of profiling of energy distribution the choice of the spherical configuration for the VG-400 pilot plant installation seems to be valid

With the notion of sustainable development gaining ground, practices aimed at saving water and energy are more and more frequent, particularly the installation of hydroelectric turbine on drinking water networks. It is essential in this case that the water quality should not be deteriorated, and the water supply for consumption and fire protection has to be prioritized over energy production. Thus, a sanitary risk assessment must be done and actions to control the described critical points have to be taken. The installation of a turbine is an additional risk whereas it is not necessary for drinking water production and distribution. As a consequence, a quality management system including the turbine and additional quality water monitoring should be carried out. (authors)

Low energy use at Vaestervik sports centre

Energy Technology Data Exchange (ETDEWEB)

2009-05-15

Vaestervik, in south Sweden, has saved both energy and money since modern energy efficiency equipment was installed in its swimming pool and bowling alley. Energy use in the sports centre has so far fallen by around 830 MWh/year, and operating costs have been reduced by efficient heat recovery. Energy efficiency at the Vaestervik sports centre is a good example of how a local authority can save energy and money by installing modern equipment for ventilation and heat recovery in a facility with high energy consumption. The well-used sports centre, including a swimming pool and bowling alley, is in central Vaestervik. In 1999 the Municipality received grants from the local investment programme (LIP) to improve the facility's energy efficiency. An efficient ventilation system with a dehumidifier and heat exchanger was installed at the swimming pool, reducing the need to introduce cold air. In addition the bowling alley, which did not have heat recovery, was given a modern heat-recovery plant. - Lower operating costs due to efficient heat recovery. - Reduced energy use (electricity and district heating) for the plant at around 830 MWh/year. The modern and highly efficient units for heat recovery, dehumidification and heat exchange result in lower operating costs and reduced energy use, which means that the Municipality of Vaestervik saves energy and money. Installation at the swimming pool resulted in slightly higher air humidity, but a relative humidity of 60% is common in swimming pools and difficult to reduce without inconveniencing bathers. A new fan room installed in the roof contributed to higher than anticipated costs, but the financial and economic gains outweigh these. New frequency-controlled circulation pumps for the pool water were installed in 2007. They are to have occupancy control capability, giving a further improvement of energy saving and heat recovery

This article comments legal evolutions regarding renewable energies in France. First, it addresses the wind energy sector: validation of the ICPE (classified installation for the protection of the environment) classification of wind turbines, severe uncertainties regarding purchase tariff, possible new legal measures in favour of the wind sector, jurisprudence (more wind turbines in coastal towns, relationship between wind turbines and landscape in the urban planning code, cancellation of a construction request rejection, relationship between radars and wind turbines, informational characteristic of the impact study). The second part concerns the solar energy sector: a still unsteady legal framework (delays in tariff homologation and bidding organisation, new statements in favour of photovoltaic, mandatory character of the delay of transmission of a connection offer, partial cancellation of a ministerial order creating the CEIAB committee), and new precision in urban planning regulations applicable to solar installations. The third part addresses the biogas sector: ICPE rules for methanization installations, energy performance of farm mechanisation installations, a decree project modifying some aspects of a combustion installation, evolution of STEP sludge waste. Finally, some legal texts concerning hydroelectric installations are evoked

An overview of the sustainability of solid waste management at military installations

Energy Technology Data Exchange (ETDEWEB)

Borglin, S.; Shore, J.; Worden, H.; Jain, R.

2009-08-15

Sustainable municipal solid waste management at military solutions necessitates a combined approach that includes waste reduction, alternative disposal techniques, and increased recycling. Military installations are unique because they often represent large employers in the region in which they are located, thereby making any practices they employ impact overall waste management strategies of the region. Solutions for waste sustainability will be dependent on operational directives and base location, availability of resources such as water and energy, and size of population. Presented in this paper are descriptions of available waste strategies that can be used to support sustainable waste management. Results presented indicate source reduction and recycling to be the most sustainable solutions. However, new waste-to-energy plants and composting have potential to improve on these well proven techniques and allow military installations to achieve sustainable waste management.

Solar Schools Assessment and Implementation Project: Financing Options for Solar Installations on K-12 Schools

Energy Technology Data Exchange (ETDEWEB)

Coughlin, J.; Kandt, A.

2011-10-01

This report focuses on financial options developed specifically for renewable energy and energy efficiency projects in three California public school districts. Solar energy systems installed on public schools have a number of benefits that include utility bill savings, reductions in greenhouse gas emissions (GHGs) and other toxic air contaminants, job creation, demonstrating environmental leadership, and creating learning opportunities for students. In the 2011 economic environment, the ability to generate general-fund savings as a result of reducing utility bills has become a primary motivator for school districts trying to cut costs. To achieve meaningful savings, the size of the photovoltaic (PV) systems installed (both individually on any one school and collectively across a district) becomes much more important; larger systems are required to have a material impact on savings. Larger PV systems require a significant financial commitment and financing therefore becomes a critical element in the transaction. In simple terms, school districts can use two primary types of ownership models to obtain solar installations and cost savings across a school district. The PV installations can be financed and owned directly by the districts themselves. Alternatively, there are financing structures whereby another entity, such as a solar developer or its investors, actually own and operate the PV systems on behalf of the school district. This is commonly referred to as the 'third-party ownership model.' Both methods have advantages and disadvantages that should be weighed carefully.

Renewable energies have potential for supplying of relatively clean and mostly local energy. Wind energy generation is expected to increase in the near future and has experienced dramatic growth over the past decade in many countries. Offshore winds are generally stronger and more constant than onshore winds in many areas. The economic feasibility for utilization of offshore wind energy depends on the favorable wind conditions in the area. The present paper analyses offshore wind speed in global scale and also studies feasibility of introducing this technology for harnessing wind in Persian Gulf, Caspian Sea, Urmia Lake and Gulf of Oman. Wind speed data were collected from different sources. The ocean surface winds at a 10 m height from satellite passes as processed by NOAA/NESDIS, from near real-time data collected by NASA/JPL's Sea Winds Scatterometer aboard the QuikSCAT. Development of renewable energy is one of priority research goals in Iran. There are many installed wind turbines in suitable regions like Manjil and Binalood, but there has not been any offshore wind installation yet in Iran. It is suggested that policy makers to invest and pay more attentions toward harnessing renewable energy sources like offshore wind in Persian Gulf and Gulf of Oman in southern parts of Iran.

Final Technical Report for the Recovery Act Project for the Installation of a Low Flow Unit at the Abiquiu Hydroelectric Facility. The Abiquiu hydroelectric facility existed with two each 6.9 MW vertical flow Francis turbine-generators. This project installed a new 3.1 MW horizontal flow low flow turbine-generator. The total plant flow range to capture energy and generate power increased from between 250 and 1,300 cfs to between 75 and 1,550 cfs. Fifty full time equivalent (FTE) construction jobs were created for this project - 50% (or 25 FTE) were credited to ARRA funding due to the ARRA 50% project cost match. The Abiquiu facility has increased capacity, increased efficiency and provides for an improved aquatic environment owing to installed dissolved oxygen capabilities during traditional low flow periods in the Rio Chama. A new powerhouse addition was constructed to house the new turbine-generator equipment.

Bergeron, S.M.; Strickland, D.J.; Pearson, R.

1987-10-01

A vadose zone monitoring system was installed in a sanitary landfill near the Y-12 facility on the Department of Energy's Oak Ridge, Tennessee Reservation. The work was completed as part of the LLWDDD program to develop, design, and demonstrate new low level radioactive waste disposal monitoring methods. The objective of the project was to evaluate the performance of three types of vadose zone samplers within a similar hydrogeologic environment for use as early detection monitoring devices. The three different types of samplers included the Soil Moisture Equipment Corporation Pressure-Vacuum samplers (Models 1920 and 1940), and the BAT Piezometer (Model MK II) manufactured by BAT Envitech, Inc. All three samplers are designed to remove soil moisture from the vadose (unsaturated) zone. Five clusters of three holes each were drilled to maximum depths of 45 ft around part of the periphery of the landfill. Three samplers, one of each type, were installed at each cluster location. Water samples were obtained from 13 of the 15 samplers and submitted to Martin Marietta for analysis. All three samplers performed satisfactorily when considering ease of installation, required in-hole development, and ability to collect water samples from the vadose zone. Advantages and disadvantages of each sampler type are discussed in the main report

This final report for the Swiss Federal Office of Energy (SFOE) describes the results of investigations made on a biogas plant installed at a production facility for flavours and plant extracts for the pharmaceuticals and foodstuffs industry. The installation, which ferments wastes to produce biogas for a combined heat and power installation, exhibited irregular biogas production and strongly varying methane content in the biogas. The investigations made and the solutions tried out are described. After the addition of selenium to the solid wastes brought little success, liquid manure was used as an additive. First results are discussed, which show that the methane concentration could be stabilised. Further, the report describes how the control system for the plant's absorption chillers was modified to improve performance.

Japan, world leader of photovoltaic energy

Since the beginning of the 1970's, the potentialities of photovoltaic energy has been recognized by the Japanese government which has sustained this technology in two ways. First, by the financing of R and D programs, and second, by giving subsidies to citizens for the installation of solar panels. Today, Japan is the world leader of photovoltaic energy, both for the installed power and for the production of solar cells. In 2003, the International Energy Agency was reporting 1.809 GW of worldwide installed capacity among which 48% was in Japan (0.86 GW) with respect to 0.4 GW in Germany, 0.275 GW in the USA and only 20 MW in France. This capacity would have exceeded 1.1 GW at the end of 2004. Half of the solar modules are manufactured in Japan. The ministry of economy, trade and industry (METI) has fixed ambitious goals for 2010: the overall new energy sources much represent 3% of the primary energy (with respect to 1% today) and the installed capacity must reach 4.8 GW. The road-map of the New Energy and Industrial Technology Development Organisation (NEDO) foresees 100 GW by 2030. (J.S.)

An analysis of the energy policy programs presented since 1973 shows that all government coalitions have been known in the past 45 years in principle for the objectives of security of supply, efficiency and affordability as well as environmental protection and conservation of resources - together with the statement that these goals should be pursued on an equal footing. In fact, there has never been this ''consonance'' of goals. Rather, concrete events or political currents have led to a changing prioritization of individual goals. At the same time, the intensity of government intervention in the management of supply and demand has changed. [German] Eine Analyse der seit 1973 vorgelegten energiepolitischen Programme zeigt: Alle Regierungskoalitionen haben sich in den vergangenen 45 Jahren im Grundsatz zu den Zielen Versorgungssicherheit, Wirtschaftlichkeit und Bezahlbarkeit sowie Umweltschutz und Ressourcenschonung bekannt - verknuepft mit der Aussage, dass diese Ziele gleichrangig zu verfolgen seien. Tatsaechlich hat es diesen ''Gleichklang'' der Ziele nie gegeben. Konkrete Ereignisse oder politische Stroemungen haben vielmehr zu einer wechselnden Priorisierung einzelner Ziele gefuehrt. Parallel dazu hat sich die Eingriffsintensitaet des Staates in die Steuerung von Angebot und Nachfrage veraendert.

Metrology and quality assurance for European XFEL long flat mirrors installation

Science.gov (United States)

Freijo Martín, Idoia; Vannoni, Maurizio; Sinn, Harald

2017-06-01

The European XFEL is a large-scale user facility under construction in Hamburg, Germany. It will provide a transversally fully coherent X-ray radiation with outstanding characteristics: high repetition rate (up to 2700 pulses with a 0.6 milliseconds long pulse train at 10Hz), short wavelength (down to 0.05 nm), short pulses (in the femtoseconds scale) and high average brilliance (1.6x1025 photons / s / mm2 / mrad2/ 0.1% bandwidth)1. Due to the short wavelength and high pulse energies, mirrors need to have a high-quality surface, have to be very long (1 m), and at the same time an effective cooling system has to be implemented. Matching these tight specifications and assessing them with high precision optical measurements is very challenging. The mirrors go through a complicated and long process, starting from classical polishing to deterministic polishing, ending with a special coating and a final metrology assessment inside their mechanical mounts just before the installation. The installation itself is also difficult for such big mirrors and needs special care. In this contribution we will explain how we implemented the installation process, how we used the metrology information to optimize the installation procedure and we will show some preliminary results with the first mirrors installed in the European XFEL beam transport.

Geothermal energy in the world energy scenario

International Nuclear Information System (INIS)

Barbier, E.

1989-01-01

This paper reports on the world energy consumption between 1960 and 1984 from primary energy sources (coal, natural gas, oil, hydropower, nuclear energy) and the same in percentages from 1925. This highlights the diminishing role of coal and the increased consumption of gas and oil. The latter has stabilized around 42% of the total after the drop in demand resulting from the oil crisis of 1973. The world energy consumption has then been divided into industrialized and developing countries. It appears that the latter, with a population equal to 68% of the total world population, consumed 23% of the world energy in 1982. Furthermore, the consumption figures show that the demand for domestic energy is much smaller in developing countries, and it is well-known that domestic energy consumed is one of the parameters used to assess standard of living. The total installed electric capacity throughout the world is then reported, divided between developed and developing countries, showing that the latter consumed 11% of all the electricity generated in the world in 1981. The world installed electric power of geothermal origin at the end of 1985 is shown, along with estimates for 1990. Geothermal energy represents 0.2% of the world electric power. This is obviously a small figure and indicates that geothermal energy plays a minor role on the world energy scene. However, if we distinguish between industrialized and developing countries, we can observe that, with their currently limited electrical consumption but good geothermal prospects, the developing countries could achieve quite a significant contribution to their total electric energy from that of geothermal origin, increasing at the moment from 3 to 19%. Finally, a comparison is made between electricity generating costs of different sources, showing that geothermal energy is competitive. A table illustrates the world evolution in installed geothermal capacity from 1950 to 1985. The non-electric uses of geothermal energy

Latvia is among those countries that do not have gas, coal and, for the time being, also oil resources of its own. The amount of power produced in Latvia does not meet the demand, consequently a part of the power has to be purchased from neighbouring countries. Firewood, peat and hydro resources are the only significant domestic energy resources. Massive decrease of energy consumption has been observed since Latvia regained independence. Domestic and renewable energy resources have been examined and estimated. There are already 13 modern boiler houses operating in Latvia with total installed capacity 45 MW that are fired with wood chips. Latvian companies are involved in the production of equipment. 7 small HPPs have been renewed with the installed capacity 1.85 MW. Wind plant in Ainazi has started its operation, where two modern wind turbines with the capacity of 0.6 MW each have been installed. Mechanism of tariff setting is aligned.

Energy diagnosis in industry: case of SAP Olympic

International Nuclear Information System (INIS)

Sandouidi, Ziwendtaore Frederic

2007-01-01

The control of the energy consumption became a crucial problem in the production facilities in Burkina Faso. Energy efficiency is a fact that cannot be ignored in the industrial sector because of the rise unceasingly in the prices of the petroleum. Current reality makes it possible to note the extent of the cost of electricity in our country. The economic pressures in all the sectors of the economic activity, unrestrained competitiveness, the removal of the tariff barriers in the UEMAO member countries caused many difficulties for several companies. SAP Olympic, potential consumer of electrical energy, has difficulties in control and optimize its energy consumption. The importance of this consumption of energy is the subject of great debates at this African Company of Tire. The performances of the old installations of energy are often distant from those obtained with the new installations. If it is relatively easy to carry out new powerful installations, the improvement of the energy consumption of the existing installations requires a study on a case-by-case basis, and it is not always possible to find a solution ensuring the same performances as a new installation. It is necessary to set up rigorous methods of follow-up of the calorific and electric consumption of the equipment in order to have a sufficiently precise energy assessment. The energy diagnosis indeed carries out the most relevant choices for our actions of energy saving [fr

Radiation hazards are trans-boundary. The prevention of accidents must be managed locally. But the awareness, preparedness, and the responsibilities in the case of emergencies must be managed at the local and regional level, and must rely on close interaction between the local and regional levels. The Baltic Sea Region contains over 40 nuclear reactors contributing to energy security, but also posing a potential threat to human, environmental, and political security. The aim of this paper is to integrate the four fields of security: health, environment, energy, and political by analysing awareness, preparedness responsibility and decision making related to nuclear installations. With increasing political, economical, cultural and physical (in term of energy infrastructure) integration, the region needs to take a comprehensive approach to create adequate structure for managing risks and thereby promote security.

Chen, Falin; Lu, Shyi-Min; Chi-Chuan, Wang; Chang, Yi-Lin

2008-01-01

To promote the development and application of renewable energy, under the planning and execution of Bureau of Energy of Ministry of Economical Affairs (BOEMOEA), Taiwan has implemented many measures for subsidizing the installation of RE apparatus since 2000. Besides subsidizing the installing expenses, Taiwanese government also provides incentive measures of finance/tax, such as investment deduction and accelerating depreciation. The successive growth of the amount of installing cases has apparently constructed the base of promotion and application of renewable energy; on the other hand, many barriers to be overcome were continuously discovered during the executing processes. To effectively remove these promoting barriers, the Energy Commission (the pre-BOE) issued 'Renewable Energy Development Plan' through the endorsement of Executive Yuan in January 2002. The purpose of this plan is to establish an inter-ministerial coordinating mechanism of a higher administrative level, which may focus all resources to be functioned as a working team. In the meantime, to further establish a systematically promoting mechanism, the Bureau of Energy then pushes the legislation of 'Renewable Energy Development Bill'. According to the drafted plan of this law, the power capacity of renewable energies will be 12% share of the national power installation capacity by 2020. Furthermore, in the Nuclear-free Homeland National Conference held in June 2003, government planned that the power capacity of renewable energy must reach 10% of the total power capacity in the nation by 2010. However, the share of the power capacity of renewable energy to the national power installation capacity is only 6.17%, currently, so there is still a lot of growing space for the development of renewable energy in Taiwan.

Comprehensive information and detailed data for the non-residential (NR) building stock is rather limited, although it is the fastest growing energy demand sector. This paper elaborates the approach used to determine the potential energy conservation in the Hellenic NR building stock. A major obstacle that had to be overcome was the need to make suitable assumptions for missing detailed primary data. A qualitative and quantitative assessment of scattered national data resulted in a realistic assessment of the existing NR building stock and energy consumption. Different energy conservation scenarios and their impact on the reduction of CO 2 emissions were evaluated. Accordingly, the most effective energy conservation measures are: addition of thermal insulation of exposed external walls, primarily in hotels and hospitals; installation of energy efficient lamps; installation of solar collectors for sanitary hot water production, primarily in hotels and health care; installation of building management systems in office/commercial and hotel buildings; replacement of old inefficient boilers; and regular maintenance of central heating boilers

Wind energy status in renewable electrical energy production in Turkey

2010-01-01

Main electrical energy sources of Turkey are thermal and hydraulic. Most of the thermal sources are derived from natural gas. Turkey imports natural gas; therefore, decreasing usage of natural gas is very important for both economical and environmental aspects. Because of disadvantages of fossil fuels, renewable energy sources are getting importance for sustainable energy development and environmental protection. Among the renewable sources, Turkey has very high wind energy potential. The estimated wind power capacity of Turkey is about 83,000 MW while only 10,000 MW of it seems to be economically feasible to use. Start 2009, the total installed wind power capacity of Turkey was only 4.3% of its total economical wind power potential (433 MW). However, the strong development of wind energy in Turkey is expected to continue in the coming years. In this study, Turkey's installed electric power capacity, electric energy production is investigated and also Turkey current wind energy status is examined. (author)

Geothermal energy

Vuataz, F.-D.

2005-01-01

This article gives a general overview of the past and present development of geothermal energy worldwide and a more detailed one in Switzerland. Worldwide installed electrical power using geothermal energy sources amounts to 8900 MW el . Worldwide utilization of geothermal energy for thermal applications amounts to 28,000 MW th . The main application (56.5%) is ground-coupled heat pumps, others are thermal spas and swimming pools (17.7%), space heating (14.9%), heating of greenhouses (4.8%), fish farming (2.2%), industrial uses (1,8%), cooling and melting of snow (1.2%), drying of agricultural products (0.6 %). Switzerland has become an important user of geothermal energy only in the past 25 years. Earlier, only the exploitation of geothermal springs (deep aquifers) in Swiss thermal baths had a long tradition, since the time of the Romans. Today, the main use of geothermal energy is as a heat source for heat pumps utilizing vertical borehole heat exchangers of 50 to 350 meters length. 35,000 installations of this type with heating powers ranging from a few kW to 1000 kW already exist, representing the highest density of such installations worldwide. Other developments are geostructures and energy piles, the use of groundwater for heating and cooling, geothermal district heating, the utilization of draining water from tunnels and the project 'Deep Heat Mining' allowing the combined production of heat and electric power

The installation of the LHC experimental insertions, and particularly the installation of the low-beta quadrupoles, raises many technical challenges due to the stringent alignment specifications and to the difficulty of access in very confined areas. The compact layout with many lattice elements, vacuum components, beam control instrumentation and the presence of shielding does not allow for any improvisation in the installation procedure. This paper reviews all the constraints that need to be taken into account when installing the experimental insertions. It describes the chronological sequence of installation and discusses the technical solutions that have been adopted.

2009-01-01

PV-grid-connected systems are worldwide installed because it allows consumer to reduce energy consumption from the electricity grid and to feed the surplus energy back into the grid. The system needs no battery so therefore the system price is very cheap comparing to other PV systems. PV-grid-connected systems are used in buildings that already hooked up to the electrical grid. Finding efficiency of the PV-grid-connected system can be done by using a standard instrument which needs to disconnect the PV arrays from the grid before measurement. The measurement is also difficult and we lose energy during the measurement. This paper will present the system performance of a PV-grid-connected system installed in Thailand by using a monitoring system. The monitored data are installed by acquisition software into a computer. Analysis of monitored data will be done to find out the system performance without disconnecting the PV arrays from the system. The monitored data include solar radiation, PV voltage, PV current, and PV power which has been recorded from a 5 kWp system installed of amorphous silicon PV at Rajamangala University of Technology Suvarnabhumi, Nonthaburi, Thailand. The system performance of the system by using the data monitored is compared to the standard instrument measurement. The paper will give all details about system components, monitoring system, and monitored data. The result of data analysis will be fully given. (author)

One of the leading printing firms im Europe covers its energy requirements for thermal and cooling energy from a Power-Heat-Cooling-combined installation. The central element of the installation is a gas and steam process with 3 gas turbines and a steam turbine with an electrical performance of 20,5 MW in total. The waste heat extracted from the combined cycle-process is used to produce refrigeration using absorption refrigeration equipment and to provide district heating for internal and external firms. The waste heat is used several times in the refrigerating centre through cascade switching. The solvent-containing vitiated air from the offset printing machines present is used in the combined cycle-process to generate electricity. The vitiated air is cleaned in TNV equipment and the hot waste gases used to produce steam. The process steam produced is sent into the combined cycle-progress installation and so used for the generation of more electricity. In 1998 the atmosphere was relieved of the burden of about 78 000 t of the greenhouse gas carbon dioxide, together with a comprehensive reduction of air pollutants such as nitrous oxides (by 60%), carbon oxides (by 49%) sulphur oxides and dust (by 100% in each case), by the environment and resources conserving technology of the PHC-combined installation.

Sustainable construction of buildings is stimulated by the Dutch government, while it is one of the options to realize reduction of CO2 emission. It is not only a matter of applying sustainable building materials and thermal insulation, but also technical aspects of installations play a part, e.g. low temperature heating, solar energy, heat pumps, underground heat and cold storage, high-efficient ventilation, etc. However, it appears that for a large-scale application of those techniques there are still some barriers with respect to knowledge and acceptation of sustainable installations by the market. Next to stimulation by the Dutch government private enterprises develop initiatives in this direction. Two of those initiatives are discussed in this article: 'Wasco Groothandelsgroep Centrale Verwarming' (wholesale company for central heating systems ) in Twello, Netherlands, set up the Wasco Energy Centre, and 'Stichting Dubotechniek' (foundation for sustainable building technology) in Zaltbommel, Netherlands. Both initiatives concern information centers to show the performance of and provide information on sustainable installations.

The design and installation of Solar Home Systems in rural Cambodia

Directory of Open Access Journals (Sweden)

Rebecca Alice Watts

2016-09-01

Full Text Available This study contends that solar home systems (SHS are an appropriate solution to provide affordable, reliable and clean electricity in rural Cambodia. SHS provide decentralised electricity suitable for the electricity needs of rural households and with the decreasing cost of solar energy technologies, SHS are becoming an increasingly competitive source of energy. This study details the design and installation of two SHS in a rural community in Cambodia. The SHS have replaced the use of kerosene lamps and supplemented car battery usage, which has generated a cost saving of USD$2.50-3.20 per month. The SHS have increased the hours of quality lighting making it possible for users to improve educational outcomes by studying at night and participating in private education classes as well as potentially extending their working hours that provides an opportunity to increase their income. Community involvement in the installation of SHS and participation in an education program has ensured transfer of knowledge about system operation and maintenance at a local level that has ensured economic, social and environmental were benefits. This study builds a case in support of solar energy at the household level in rural Cambodia and makes recommendations for the deployment of SHS in rural communities throughout the developing world.

2006-01-01

Presently work, the adaptation and installation of an accelerating tube (that operates as Injector of 75 KV), to the source of ions 'Sputtering Negative Ion Cesium Source', (SNICS), of the Tandem Accelerator EN of the Nuclear Center is presented. This work allowed to increase the acceleration energy from the negative ions to the beginning of the tank. Since the beam energy that it was possible to obtain from the source, it was very below the design parameters, what limited in great measure the reach of the experiments that could be carried out, was urgent to carry out the installation of the accelerator tube mentioned to the source. The limitations in the available resources had impeded this improvement and it took time being deferred. The added value of this adaptation, it resides in that it is a specialized work and it was, finally, carried out with success by the workers of the Accelerator, adapting to the few existent resources and achieving with it a substantial improvement of the bombing currents obtained for the samples of the investigators.

The Advanced Energy led SEGIS-AC program represents an industry partnership driven collaborative effort to continue to lower the barriers to increasing penetration of PV on the grid while also lowering overall system cost consistent with the Department of Energy SunShot Initiative. The SEGIS-AC program follows the DOE sponsored three year SEGIS program, which had similar high level goals, but with a broader exploratory scope. In SEGIS-AC, the team carries forward a new communications based islanding detection technology developed during the SEGIS program. Advanced utility interactive controls are further developed, and a storage inverter system is developed focused on intermittency mitigation due to cloud induced transients. Communications based island detection coupled with advanced controls and a storage system are shown to improve utility distribution feeder performance and to enable increased solar PV penetration levels. By the conclusion of the program, multiple utilities and customers have expressed awareness and desire to make use of the technologies developed and demonstrated under this program. This factor has led the Advanced Energy led team to deem the program an overall success. The report following details the technologies developed and demonstrated, as well as industry engagement.

Energy Technology Data Exchange (ETDEWEB)

Krebs, F.

1977-03-01

Water producing and electrical generating facilities had to be increased on the Spanish Canary Island of Lanzarote for it to develop beyond its 1972 status. The Ministry of Public Works, prepared specifications for a turnkey installation of two 2500 M/sup 3//D desalting plants and a 5 MW (net) generating system. In 1973 through international competition Babcock and Wilcox, Espanola won a contract to build the installation. In December 1975 the construction of the project was completed. In early January 1976 the first line was producing 103% of the rated production at a thermal efficiency of 120% of the rated value. The second line was modified to operate at a reduced maximum brine temperature and commissioned. This plant was brought to full production which was 115% of the rated production in 2/sup 1///sub 2/ days. Problems and delays during the commissioning, were minimal. A 5 days performance test of the installation was run. During this test the water production was 111/sup 1///sub 2/% of the rated value at a specific energy consumption of 93% of the rated value while the maximum brine temperature was maintained 6/sup 0/C less than the design value. The high performances were achieved because the plants were well designed and built and properly commissioned. During the first 4/sup 1///sub 2/ months that the owner operated the installation it provided water and power as demanded. During that time the average plant production was 107% of the rated capacity.

Planning of installations in prefabricated buildings

Directory of Open Access Journals (Sweden)

Stanojević Ana D.

2014-01-01

Full Text Available Planning installations is becoming an increasing problem in construction, because the number of devices for technical supply is constantly increasing with continual progress in science and technology. Since the installations of the building can not be viewed unrelated of the construction, problem of its planning is more complicated in prefabricated buildings because the elements of construction are prefabricated. Planning was formerly performed by embedding the installation in prefabricated elements. This method had a lot of flaws, and modern approach tends setting installation out of prefabricated elements except when the traditional approach proves as economical. Although the hot water heating with radiators is the most practical way of heating in prefabricated buildings, the under floor heating systems have greater and greater use. Today, prefabricated sanitary cabins have a huge use and they are much more economical in comparison to special panels for bathrooms that were once create. Approaches in terms of planning electrical installation are different, but for conventional constructed buildings, as well as prefabricated buildings, the use of lightweight prefabricated walls with embedded installations, today is recommended, when the room is loaded with a large number of this installations and if it is possible.

This paper proposes an optimization algorithm to find the maximum wind installation in a radial distribution network. The algorithm imposes a limit on the amount of wind energy that can be curtailed annually. The algorithm implements the wind turbine reactive power control and wind energy...... curtailment using sensitivity factors. The optimization is integrated with Monte Carlo simulation to account for the stochastic behavior of load demand and wind power generation. The proposed algorithm is tested on a real 20 kV Danish distribution system in Støvring. It is demonstrated that the algorithm...... executes reactive compensation and energy curtailment sequentially in an effective and efficient manner....

Higher standards of performance and reliability in the power plants of large particle accelerators necessitate increasing use of automation. The CERN (European Nuclear Research Centre) in Geneva started to employ process computers for plant automation at an early stage in its history. The great complexity and extent of the plants for high-energy physics first led to the setting-up of decentralized automatic systems which are now being increasingly combined into one interconnected automation system. One of these automatic systems controls and monitors the extensive power supply installations for the main ring magnets in the experimental zones. (orig.) [de

Statistical analysis of installed wind capacity in the United States

There is a large disparity in the amount of wind power capacity installed in each of the states in the U.S. It is often thought that the different policies of individual state governments are the main reason for these differences, but this may not necessarily be the case. The aim of this paper is to use statistical methods to study the factors that have the most influence on the amount of installed wind capacity in each state. From this analysis, we were able to use these variables to accurately predict the installed wind capacity and to gain insight into the driving factors for wind power development and the reasons behind the differences among states. Using our best model, we find that the most important variables for explaining the amount of wind capacity have to do with the physical and geographic characteristics of the state as opposed to policies in place that favor renewable energy. - Highlights: • We conduct a statistical analysis of factors influencing wind capacity in the U.S. • We find that state policies do not strongly influence the differences among states. • Driving factors are wind resources, cropland area, and available percentage of land

This paper describes three wind energy projects implemented in Alaska. The first, a sustainable technology energy partnerships (STEP) wind energy deployment project in Kotzebue will install 6 AOC 15/50 wind turbines and connect to the existing village diesel grid, consisting of approximately 1 MW average load. It seeks to develop solutions to the problems of arctic wind energy installations (transport, foundations, erection, operation, and maintenance), to establish a wind turbine test site, and to establish the Kotzebue Electric Association as a training and deployment center for wind/diesel technology in rural Alaska. The second project, a large village medium-penetration wind/diesel system, also in Kotzebue, will install a 1-2 MW windfarm, which will supplement the AOC turbines of the STEP project. The program will investigate the impact of medium penetration wind energy on power quality and system stability. The third project, the Alaska high-penetration wind/diesel village power pilot project in Wales will install a high penetration (80-100%) wind/diesel system in a remote Alaskan village. The system will include about 180 kW installed wind capacity, meeting an average village load of about 60 kW. This program will provide a model for high penetration wind retrofits to village diesel power systems and build the capability in Alaska to operate, maintain, and replicate wind/diesel technology. The program will also address problems of: effective use of excess wind energy; reliable diesel-off operation; and the role of energy storage.

2015-12-01

As objectives of development are high for renewable energies (they are supposed to cover 50 per cent of new energy needs by 2035), pumped energy transfer stations are to play an important role in this respect. The author first discusses the consequences of the development of renewable energies on the exploitation of electric grids: issue of intermittency for some of them, envisaged solutions. Then, he addresses one of the solutions: the storage of electric power. He notices that increasing the potential energy of a volume of water is presently the most mature solution to face massive needs of the power system. Dams and pumped energy transfer stations represent now almost the whole installed storage power in the world. The author then presents these pumped energy transfer stations: principle, brief history (the first appeared in Italy and Switzerland at the end of the 1890's). He indicates the various parameters of assessment of such stations: maximum stored energy, installed power in pumping mode and turbine mode, time constant, efficiency, level of flexibility. He discusses economic issues. He describes and comments the operation of turbine-pump groups: ternary groups, reversible binary groups. He discusses barriers to be overcome and technical advances to be made for varying speed groups and for marine stations. He finally gives an overview (table with number of stations belonging to different power ranges, remarkable installations) of existing stations in China, USA, Japan, Germany, Austria, Spain, Portugal, Italy, Switzerland, France and UK, and indicate predictions regarding storage needs at the world level. Some data are finally indicated for the six existing French installations

Nuclear energy in Korea

International Nuclear Information System (INIS)

Ahn, J.-H.

2000-01-01

The total electricity generated in 1998 was 215,300 GWh with 43,261 MWe of total installed capacity of electric power, while in 1978 when the first Nuclear Power Plant began operation it was 31,510 GWh with 6,916 MWe installed capacity. The share of nuclear power generation in 1998 increased up to 41.7%. Currently, 16 units of nuclear power are operating with an additional four units under construction. Nuclear power has contributed to enhancing energy security and supplying stable energy for Korea. The government's strong commitment to the nuclear power program together with a long-term national policy resulted in favorable conditions for KEPCO to manage the program and promote increasing levels of national participation in successive nuclear power projects. The role of nuclear power as a sustainable energy resource can not be emphasized enough with respect to global environmental issues. Increasing the share of nuclear power in the total installed capacity for electricity generation will undoubtedly play a very important role. (author)

The energy-saving effect of single-room control of heating systems was investigated. For this purpose, a single-room control system was installed in a university building of 1961, and energy savings were monitored for a 2-year period, with the following results: 1. The potential savings amounted to 28% in both test years. 2. Different operating strategies were used in order to assess the contribution of heating system components. 3. The amortization period is less than 8 years, i.e. much less than the expected life of the systems. 4. Appropriate technical facilities improve the operation and control of a heat supply system in large buildings. 5. Proposals for improving the functionality of single room control systems were developed. 6. Recommendations were given on how to best modernize the control systems of large buildings. 7. The results can be applied to similar buildings as well. [German] Das Forschungsprojekt hatte folgende Ziele: 1. Die Ermittlung des Energie-Einsparpotentials 2. die daraus resultierende Wirtschaftlichkeit 3. die Optimierung der Regelstrategien 4.

Bratic, S.; Krajacic, G.; Duic, N.; Cotar, A.; Jardas, D.

2011-01-01

In order to analyze energy self-sufficient island, example of a smaller island, connected to the power system of a bigger island with an undersea cable, was taken. Mounting substation 10/0,4 is situated on the island and for the moment it provides enough electricity using the medium voltage line. It is assumed that the island is situated on the north part of the Adriatic Sea. The most important problem that occurs on the island is the population drop that occurs for a significant number of years, therefore, life standard needs to be improved, and economic development needs to be encouraged immediately. Local authorities to stimulate sustainable development on the island through different projects, to breath in a new life to the island, open new jobs and attract new people to come live there. Because of the planned development and increase of the population, energy projects, planned as a support to sustainable development, and later achievement of the energy self-sufficiency, is described in this paper. Therefore, Rewisland methodology appliance is described taking into the account three possible scenarios of energy development. Each scenario is calculated until year 2030. Also, what is taken into the account is 100% usage of renewable sources of energy in 2030. Scenario PTV, PP, EE - This scenario includes installation of solar photovoltaic modules and solar thermal collectors on the buildings roofs, as well as well as implementation of energy efficiency on the island (replacement of the street light bulbs with LED lightning, replacement of the old windows and doors on the houses, as well as the installation of the thermal insulation). Scenario PV island - This scenario, similarly to the previous one, includes installation of solar photovoltaic modules and solar thermal collectors an the residential buildings, as well as the 2 MW photovoltaic power plant and ''Green Hotel'', a building that satisfies all of its energy needs completely from renewable energy sources

A 70 kW photovoltaic installation has been constructed on the roof of the new Building 6 of Geneva Palexpo, a compound that hosts various conferences, exhibitions and sporting or other events, counting almost 1.5 million visitors a year, including the International Car Show, which alone attracts more than 700,000 visitors each year. The purpose of this installation is the indirect supply of recharging terminals for electric vehicles. The solar installation and the electric vehicle recharging terminals support an information campaign on solar energy and 'sustainable' mobility. For this purpose various explanatory signs have been placed inside the Geneva Palexpo halls and a promotional stand for renewable energy and 'sustainable' transport was placed inside the International Car Show 2003. This stand had some success: more than 4,000 people took part in the competition organised on this occasion. (author)

Why invest in wind energy? Career incentives and Chinese renewable energy politics

International Nuclear Information System (INIS)

Cao, Xun; Kleit, Andrew; Liu, Chuyu

2016-01-01

We study wind development at the provincial level in China, modelling installed wind capacities as a function of both economics and politics. We assume that the top provincial officials desire to maximize their chances of promotion under the Chinese cadre evaluation system. We expect that those with the strongest incentives to perform in order to achieve promotion would work harder to comply with the central government’s policy agenda to promote renewable energy. Collecting and testing data on provincial leaders’ characteristics, we find that provinces governed by party secretaries who were approaching the age of 65 are associated with significantly higher level of wind installed capacities. This result supports the political tournaments theory of Chinese politics. We also find that better educated party secretaries are likely to be more supportive of renewable energy, implying that education acts to encourage provincial leaders to support the central government’s policy. - Highlights: • No negative association between fossil fuel production and wind energy development. • Provinces with party secretaries approaching the age of 65 have more installed capacities. • Better educated party secretaries are likely to be more supportive of renewable energy.

Quality assurance in the structural installations of nuclear power stations

International Nuclear Information System (INIS)

Schnellenbach, G.; Wrage, S.

1985-01-01

The concept of quality assurance distinguishes between self-monitoring of the design, manufacturing and executing firms and external monitoring by state institutions or by experts commissioned by them. The long-term control of structures is within the area of responsibility of the owner. This quality assurance concept is controlled in detail by statutes, which clearly define responsibilities. This structural engineering quality assurance system also forms the basis for the design, construction and utilization of structural installations of nuclear power stations; requirements emanating from the Atomic Energy Acts for the structural installations demand, however, to some extent a sharpening of self- and external monitoring. Therefore, today a quality concept has been developed for the important engineering safety-related buildings of nuclear power stations. This concept takes account of the strict requirements imposed and fulfils the requirement of KTA 1401. (orig.) [de

A procedure for analysing energy savings in multiple small solar water heaters installed in low-income housing in Brazil

International Nuclear Information System (INIS)

Giglio, Thalita; Lamberts, Roberto; Barbosa, Miriam; Urbano, Mariana

2014-01-01

Due to government subsidies, Brazil has witnessed an increase in the installation and use of small solar water heating systems in low-income housing projects. Although the initiative has reduced the load curve during peak times due to the reduced use of electric showerheads, measurement and verification (M and V) are needed to validate the savings. M and V procedures should take into account the social and economic variability of low-income housing developments. To improve M and V in low-income housing projects, this paper presents a methodology for identifying homogeneous subgroups based on their energy-saving potential. This research strategy involved a cluster analysis designed to improve the understanding of what energy savers and other influencing factors exist. A case study in Londrina Brazil was undertaken with 200 low-income families. Five clusters, created based on savings potential, were defined. The results showed that only two clusters demonstrated good electricity savings, representing 47% of families. However, two clusters, or 37%, did not provide satisfactory savings, and the other 16% did not provide any consumption history due to previous use of illegal city electricity connection practices. Therefore, studies confirm the need for a detailed measurement of the representative subgroups to assess the influence of human behaviour on potential SWHS-induced savings. - Highlights: • M and V is necessary to improve solar collector-area-based subsidy programmes. • M and V in large-scale sample should contemplate the social and economic variability. • Samples with homogeneous subgroups contribute to a consistent energy-saving M and V. • Solar Water Heaters in some cases may not offer energy saving in a low-income context. • SWH performance decreases with low educational level and difficulty of operation

As an important part of nuclear power plant construction, nuclear island installation mainly involves main equipment installation, pipeline installation, associated procedure examination and other important tasks. However, due to the nuclear island installation management changing from single project to multi-projects, the problems such as professional management of nuclear island installation and the lack of technical staff become more and more prominent and become one of the key restricts to the work of nuclear island installation. Based on analysis of the single project, single-base nuclear island installation management and practice, combined with the current situation that multi-project and multi-base construction of nuclear power are carrying out at the same time, this paper proposes a new management model of nuclear island installation.

A General Purpose High Performance Linux Installation Infrastructure

International Nuclear Information System (INIS)

Wachsmann, Alf

2002-01-01

With more and more and larger and larger Linux clusters, the question arises how to install them. This paper addresses this question by proposing a solution using only standard software components. This installation infrastructure scales well for a large number of nodes. It is also usable for installing desktop machines or diskless Linux clients, thus, is not designed for cluster installations in particular but is, nevertheless, highly performant. The infrastructure proposed uses PXE as the network boot component on the nodes. It uses DHCP and TFTP servers to get IP addresses and a bootloader to all nodes. It then uses kickstart to install Red Hat Linux over NFS. We have implemented this installation infrastructure at SLAC with our given server hardware and installed a 256 node cluster in 30 minutes. This paper presents the measurements from this installation and discusses the bottlenecks in our installation

2004-01-01

This article discusses the use of solar energy to provide summer cooling. Starting with centuries-old methods of adiabatic cooling used in the southern valleys of the Grisons in Switzerland, various methods of using solar energy to generate cold are examined. The article mentions the increasing load being placed on electricity supplies by conventional cooling systems and describes two real-life installations that use solar energy to generate cold. The first installation described uses evacuated tube collectors to provide around 45,000 kilowatt-hours of energy for an office complex, of which one third is used in summer to generate cold. The second installation features flat-plate collectors and two absorption refrigeration machines. Financial and environmental balances are presented and discussed

This paper deals with the experimental investigation and analysis of the energy and environmental performance of a green roof system installed in a nursery school building in Athens. The investigation was implemented in two phases. During the first phase, an experimental investigation of the green roof system efficiency was presented and analysed, while in the second one the energy savings was examined through a mathematical approach by calculating both the cooling and heating load for the summer and winter period for the whole building as well as for its top floor. The energy performance evaluation showed a significant reduction of the building's cooling load during summer. This reduction varied for the whole building in the range of 6-49% and for its last floor in the range of 12-87%. Moreover, the influence of the green roof system in the building's heating load was found insignificant, and this can be regarded a great advantage of the system as any interference in the building shell for the reduction of cooling load leads usually to the increase of its heating load.

To reduce LCOE while ensuring safety, this paper identifies principal cost drivers associated with IO&M and quantifies their impacts on LCOE. The paper identifies technology improvement opportunities and provides a basis for evaluating innovative engineering and scientific concepts developed subsequently to the study. Through the completion of a case study, an optimum IO&M strategy for a hypothetical offshore wind project is identified.

A method to deal with installation errors of wearable accelerometers for human activity recognition

International Nuclear Information System (INIS)

Jiang, Ming; Wang, Zhelong; Shang, Hong; Li, Hongyi; Wang, Yuechao

2011-01-01

Human activity recognition (HAR) by using wearable accelerometers has gained significant interest in recent years in a range of healthcare areas, including inferring metabolic energy expenditure, predicting falls, measuring gait parameters and monitoring daily activities. The implementation of HAR relies heavily on the correctness of sensor fixation. The installation errors of wearable accelerometers may dramatically decrease the accuracy of HAR. In this paper, a method is proposed to improve the robustness of HAR to the installation errors of accelerometers. The method first calculates a transformation matrix by using Gram–Schmidt orthonormalization in order to eliminate the sensor's orientation error and then employs a low-pass filter with a cut-off frequency of 10 Hz to eliminate the main effect of the sensor's misplacement. The experimental results showed that the proposed method obtained a satisfactory performance for HAR. The average accuracy rate from ten subjects was 95.1% when there were no installation errors, and was 91.9% when installation errors were involved in wearable accelerometers

Exchanging and Storing Energy. Reducing Energy Demand through Heat Exchange between Functions and Temporary Storage

Energy Technology Data Exchange (ETDEWEB)

Sillem, E.

2011-06-15

As typical office buildings from the nineties have large heating and cooling installations to provide heat or cold wherever and whenever needed, more recent office buildings have almost no demand for heating due to high internal heat loads caused by people, lighting and office appliances and because of the great thermal qualities of the contemporary building envelope. However, these buildings still have vast cooling units to cool down servers and other energy consuming installations. At the same time other functions such as dwellings, swimming pools, sporting facilities, archives and museums still need to be heated most of the year. In the current building market there is an increasing demand for mixed-use buildings or so called hybrid buildings. The Science Business Centre is no different and houses a conference centre, offices, a museum, archives, an exhibition space and a restaurant. From the initial program brief it seemed that the building will simultaneously house functions that need cooling most of the year and functions that will need to be heated the majority of the year. Can this building be equipped with a 'micro heating and cooling network' and where necessary temporarily store energy? With this idea a research proposal was formulated. How can the demand for heating and cooling of the Science Business Centre be reduced by using energy exchange between different kinds of functions and by temporarily storing energy? In conclusion the research led to: four optimized installation concepts; short term energy storage in pavilion concept and museum; energy exchange between the restaurant and archives; energy exchange between the server space and the offices; the majority of heat and cold will be extracted from the soil (long term energy storage); the access heat will be generated by the energy roof; PV cells from the energy roof power all climate installations; a total energy plan for the Science Business Centre; a systematic approach for exchanging

High and middle energy geothermal resources correspond to temperature intervals of 220-350 C and 90-180 C, respectively, and are both exploited for electricity production. Exploitation techniques and applications of high and of middle energy geothermics are different. High energy geothermics is encountered in active volcanic and tectonic zones, such as the circum-Pacific fire-belt, the lesser Antilles, the peri-Mediterranean Alpine chain or the African rift zone. The geothermal steam is directly expanded in a turbine protected against gas and minerals corrosion. About 350 high energy plants are distributed in more than 20 different countries and represent 6000 M We. The cost of high energy installed geothermal kWh ranges from 0.20 to 0.50 French Francs. Middle energy geothermics is encountered in sedimentary basins (between 2000 and 4000 m of depth), in localized fractured zones or at lower depth in the high energy geothermal fields. Heat exchangers with organic fluid Rankine cycle technology is used to produce electricity. Unit power of middle energy plants generally ranges from few hundreds of k W to few MW and correspond to a worldwide installed power of about 400 M We. The annual progression of geothermal installed power is estimated to 4 to 8 % in the next years and concerns principally the circum-Pacific countries. In France, geothermal resources are mainly localized in overseas departments. (J.S.). 3 photos

Boosting Blue Growth in a Mild Sea: Analysis of the Synergies Produced by a Multi-Purpose Offshore Installation in the Northern Adriatic, Italy

Directory of Open Access Journals (Sweden)

Barbara Zanuttigh

2015-05-01

Full Text Available In the near future, the oceans will be subjected to a massive development of marine infrastructures, including offshore wind, tidal and wave energy farms and constructions for marine aquaculture. The development of these facilities will unavoidably exert environmental pressures on marine ecosystems. It is therefore crucial that the economic costs, the use of marine space and the environmental impacts of these activities remain within acceptable limits. Moreover, the installation of arrays of wave energy devices is still far from being economically feasible due to many combined aspects, such as immature technologies for energy conversion, local energy storage and moorings. Therefore, multi-purpose solutions combining renewable energy from the sea (wind, wave, tide, aquaculture and transportation facilities can be considered as a challenging, yet advantageous, way to boost blue growth. This would be due to the sharing of the costs of installation and using the produced energy locally to feed the different functionalities and optimizing marine spatial planning. This paper focuses on the synergies that may be produced by a multi-purpose offshore installation in a relatively calm sea, i.e., the Northern Adriatic Sea, Italy, and specifically offshore Venice. It analyzes the combination of aquaculture, energy production from wind and waves, and energy storage or transfer. Alternative solutions are evaluated based on specific criteria, including the maturity of the technology, the environmental impact, the induced risks and the costs. Based on expert judgment, the alternatives are ranked and a preliminary layout of the selected multi-purpose installation for the case study is proposed, to further allow the exploitation of the synergies among different functionalities.

The National Renewable Energy Laboratory (NREL) and the U.S. Navy have worked together to demonstrate new or leading-edge commercial energy technologies whose deployment will support the U.S. Department of Defense (DOD) in meeting its energy efficiency and renewable energy goals while enhancing installation energy security. This is consistent with the 2010 Quadrennial Defense Review report1 that encourages the use of 'military installations as a test bed to demonstrate and create a market for innovative energy efficiency and renewable energy technologies coming out of the private sector and DOD and Department of Energy laboratories,' as well as the July 2010 memorandum of understanding between DOD and the U.S. Department of Energy (DOE) that documents the intent to 'maximize DOD access to DOE technical expertise and assistance through cooperation in the deployment and pilot testing of emerging energy technologies.' As part of this joint initiative, a promising waste-to-energy (WTE) technology was selected for demonstration at the Hickam Commissary aboard the Joint Base Pearl Harbor-Hickam (JBPHH), Hawaii. The WTE technology chosen is called high-energy densification waste-to-energy conversion (HEDWEC). HEDWEC technology is the result of significant U.S. Army investment in the development of WTE technology for forward operating bases.

Picture Archiving and Communication System (PACS) is difficult to implement in the best of situations, but evidence is growing that the benefits are significant. The aims of this study are to analyze the current status of full PACS and establish successful installation standard of dental PACS. Materials and Methods were based on the investigation of current working status and installation standard of PACS, and observation of variable issues to installation of dental PACS. By September 30, 2004, full PACS implementations in their facilities were 88.1% in specialized general hospitals (37 installations out of total 42 hospitals), 59.8% in general hospitals (144 installations out of total 241 hospitals), 12.3% in medical hospitals (116 installations out of total 941 hospitals) and 3.6% in dental hospitals (4 installations out of total 110 hospitals). Only 4 university dental hospitals currently have installed and are operating full PACS. Major obstacle to wide spread of dental PACS is initial high investments. Clinical environments of dental PACS differed from medical situation. Because of characteristic dental practice, the initial investments for dental PACS are generally much greater than those of medical PACS. Also new economic crisis makes users scruple. The best way to overcome these limitations is to establish an economic installation standard for dental PACS. Also the clear technical communication between the customer and the supplier before both sides are committed to the obstacles are critical to its success.

Does drywall installers' innovative idea reduce the ergonomic exposures of ceiling installation: A field case study.

Science.gov (United States)

Dasgupta, Priyadarshini Sengupta; Punnett, Laura; Moir, Susan; Kuhn, Sarah; Buchholz, Bryan

2016-07-01

The study was conducted to assess an intervention suggested by the workers to reduce the physical or ergonomic exposures of the drywall installation task. The drywall installers were asked to brainstorm on innovative ideas that could reduce their ergonomic exposures during the drywall installation work. The workers proposed the idea of using a 'deadman' (narrow panel piece) to hold the panels to the ceiling while installing them. The researcher collected quantitative exposure data (PATH, 3DSSPP) at the baseline and intervention phases and compared the phases to find out any change in the exposure while using the 'deadman'. Results showed that ergonomic exposures (such as overhead arm and awkward trunk postures and heavy load handling) were reduced at the intervention phase while using the 'deadman' with an electrically operated lift. The concept of the 'deadman', which was shown to help reduce musculoskeletal exposures during ceiling installation, can be used to fabricate a permanent ergonomic tool to support the ceiling drywall panel.

Promoting renewable energy through capacity markets: An analysis of the Russian support scheme

International Nuclear Information System (INIS)

Boute, Anatole

2012-01-01

Most existing support schemes aim to stimulate the deployment of renewable energy sources in the electricity sector on the basis of the electricity output (MW h) of renewable energy installations. Support is anchored in the electricity commodity market. In contrast to this established approach, Russia intends to promote renewable energy through the capacity market. The idea is to remunerate investors for the installed capacity (MW) of their installations, in particular for the availability of their installations to produce electricity. This article argues that, contrary to the implicit consensus, a capacity-based approach to supporting renewable energy can provide an alternative to the current output-based schemes. Capacity-based schemes limit the incentive that the operators of renewable energy installations currently have under output-based schemes to deliver electricity to the grid even in periods of low demand. These schemes also provide investors with a more predictable income flow. However, to be successful, the regulation of capacity supply – currently designed for flexible power plants – needs to accommodate the specific production patterns of variable renewable energy installations. This paper examines ways to overcome this challenge in Russia and provides more general conclusions on the complex interaction between capacity markets and renewable energy investments.

Groundwater quality monitoring well installation for Waste Area Grouping at Oak Ridge National Laboratory, Oak Ridge, Tennessee. Environmental Restoration Program

International Nuclear Information System (INIS)

Mortimore, J.A.; Lee, T.A.

1994-09-01

This report documents the drilling and installation of 18 groundwater quality monitoring (GQM) wells on the perimeter of Waste Area Grouping (WAG) 11. WAG 11 (White Wing Scrap Yard) is located on the west end of East Fork Ridge between White Wing Road and the Oak Ridge Turnpike. The scrap yard is approximately 25 acres in size. The wells at WAG 11 were drilled and developed between January 1990 and October 1990. These wells were installed to characterize and assess the WAG in accordance with applicable Department of Energy, state, and Environmental Protection Agency regulatory requirements. The wells at WAG 11 were drilled with auger or air rotary rigs. Depending on the hydrogeologic conditions present at each proposed well location, one of four basic installation methods was utilized. Detailed procedures for well construction were specified by the Engineering Division to ensure that the wells would provide water samples representative of the aquifer. To ensure conformance with the specifications, Energy Systems Construction Engineering and ERCE provided continuous oversight of field activities. The purpose of the well installation program was to install GQM wells for groundwater characterization at WAG 11. Data packages produced during installation activities by the ERCE hydrogeologists are an important product of the program. These packages document the well drilling, installation, and development activities and provide valuable data for well sampling and WAG characterization. The forms contained in the packages include predrilling and postdrilling checklists, drilling and construction logs, development and hydraulic conductivity records, and quality control-related documents

2014-01-01

After having evoked the problems created by the German energy transition in terms of energy prices, the 'Sauvons Le Climat' association makes some propositions regarding the development of renewable energies and the financial support to this development: to introduce a subsidy to the installed power, producers of intermittent renewable energy selling on the market and receiving a premium proportional to sales price. Other orientations are proposed. In a second part, Sauvons Le Climat discusses the content of the introduction of the consultation document issued by the ministry, and then proposes answers to some questions related to the content of other parts of the document which states that the present operation of support modalities disturbs the electricity market, and that an evolution towards a greater integration of renewable energies into the electric system is needed. Possible options of evolution of support to renewable energies are notably discussed, as well as challenges of transition. Documents of interest are indicated

Geothermal energy worldwide

International Nuclear Information System (INIS)

Barbier, Enriko

1997-01-01

Geothermal energy, as a natural steam and hot water, has been exploited for decades in order to generate electricity as well as district heating and industrial processes. The present geothermal electrical installed capacity in the world is about 10.000 MWe and the thermal capacity in non-electrical uses is about 8.200 MWt. Electricity is produced with an efficiency of 10-17%, and the cost of the kWh is competitive with conventional energy sources. In the developing countries, where a total installed electrical power is still low, geothermal energy can play a significant role: in El Salvador, for example, 25% of electricity comes from geothermal spring, 20% in the Philippines and 8% in Kenya. Present technology makes it possible to control the environmental impact of geothermal exploitation. Geothermal energy could also be extracted from deep geopressured reservoirs in large sedimentary basins, hot dry rock systems and magma bodies. (author)

Nordic Energy Technologies : Enabling a sustainable Nordic energy future

Vik, Amund; Smith, Benjamin

2009-10-15

A high current Nordic competence in energy technology and an increased need for funding and international cooperation in the field are the main messages of the report. This report summarizes results from 7 different research projects relating to policies for energy technology, funded by Nordic Energy Research for the period 2007-2008, and provides an analysis of the Nordic innovation systems in the energy sector. The Nordic countries possess a high level of competence in the field of renewable energy technologies. Of the total installed capacity comprises a large share of renewable energy, and Nordic technology companies play an important role in the international market. Especially distinguished wind energy, both in view of the installed power and a global technology sales. Public funding for energy research has experienced a significant decline since the oil crisis of the 1970s, although the figures in recent years has increased a bit. According to the IEA, it will require a significant increase in funding to reduce greenhouse gas emissions and limit further climate change. The third point highlighted in the report is the importance of international cooperation in energy research. Nordic and international cooperation is necessary in order to reduce duplication and create the synergy needed if we are to achieve our ambitious policy objectives in the climate and energy issue.

Offshore windfarm proposal to reduce costs of foundations and installations.

Energy Technology Data Exchange (ETDEWEB)

NONE

2007-09-04

The principle aim of this project is to develop innovative pile insertion, installation vessel pile handling and pile transfer systems that reduce the installed cost per kW of offshore wind turbine foundation installation. The project was to accomplish this by first developing a novel method of handling foundation piles without the use of craneage thereby allowing long piles of 5-6m diameter to be lifted safely in shallow water. This would extend the operating envelope by allowing work to continue without the weather constraints associated with lifting heavy loads by crane. The method would eventually reduce the size of the pile installation barge resulting in reduced installation costs. This part of the project has been satisfactorily completed, resulting in an innovative pile handling technique. Secondly a nonpercussive pile insertion method would be developed suitable for large diameter piles. The targeted aims of this method are as follows: To reduce or negate the need to handle and dispose of large amounts of spoil. To eliminate the need for piling hammers large enough to drive 6m diameter piles. These would be too heavy for the present generation of offshore cranes to lift, and the rental costs exorbitant. The advantages of these aims are: A reduction in the noise pollution produced by all percussive methods of pile driving and in particular large hammers. These noise levels are unacceptable to present and future environmental constraints. Because of the reduced drill spoil being handled compared to an industry standard full face drill, the energy consumption and therefore cost, is also reduced. Owing to the high cost and risk associated with mobilising and operating the equipment necessary for field trials in a marine environment (the cost for mobilising and operating a construction jack-up barge, all backup marine support craft, pile driving hammers and test piles can be several times the available grant funding), it was decided and agreed at an early stage

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.

This unique 'micro' installation uses an archimedian screw to produce 6.8 kW of power from a head of 1.15 m and a through-flow of 800 - 1000 litres per second. Optimisation of the project is discussed as are the effects of changing water levels above and below the screw. Winter operation is described and the mounting of gratings necessary to avoid the intake of debris is discussed. Fish-passes are looked at and the effort required for maintenance is compared with that for other types of installations. An accident that occurred is analysed and the results of energy-efficiency measurements made on the installation are presented. The report is rounded off with an evaluation of the plant's performance and a review of future work to be done.

The study outlines the considerable dynamics of technological development. Among others, the need for accelerating the market penetration of innovative measures is discussed. There are great discrepancies in the practical implementation of different measures, and it is shown that so-called low-investive measures can make a significant contribution to energy conservation. Implementation of complex measures also shows that the results achieved are strongly dependent on the energy savings goals on the one hand and on the regional or local housing situation and the resulting price levels on the other hand. This stresses the influence of the design of boundary conditions, and the question that comes up is the function of funding policy. The housing industry will have to intensify its energetic portfolio management during the next few years to cope with the new challenges, and the consumer behaviour has great influence. Here, too, efficient behaviour has considerable energy saving potential. The next few years will show if and inhowfar measures for higher transparency will have an effect. (orig.)

A new topology to mitigate the effect of shading for small photovoltaic installations in rural sub-Saharan Africa

International Nuclear Information System (INIS)

Ubisse, A.; Sebitosi, A.

2009-01-01

Many field researchers have in the past grappled with the problems of energy loss and panel damage as a result of shading and staining of PV panels after installation. A number of solutions have been proposed to try and minimize the effects of this problem in the field. The problem with all these solutions is that they address inter-panel connection topologies for very large installations. No particular attention has been paid to the topologies of individual panels. In sub-Saharan Africa most installations are single panel solar home systems and therefore small shading can result in an entire installation being disabled. This paper aims to study the effect of shading and staining on photovoltaic modules and propose a new topology that will reduce the effect of shading on the performance of individual photovoltaic modules.

Recent years have seen increasing public interest in issues related to energy saving and concern for the environment. It is important to highlight the work of public institutions in this respect. This was the motive that led the University of Valencia to finance a pilot project with the objective of studying useful initiatives for optimising energy consumption in accordance with the institution's needs as well as the incorporation of innovative and more efficient technologies. The approach was to consider various aspects ranging from the analysis of the current energy consumption and the state of the installations, through the substitution of some energy inefficient components, to the study of the possible installation of a photovoltaic solar powered electricity generation station connected to the network. Also purely technical questions on economic efficiency should not be forgotten as this could lead to a reduction in energy consumption and the optimisation of the current energy consuming equipment, since generally, it is this question that limits the possible energy saving actions.

2018-01-01

Lifetime of PV inverters is affected by the installation sites related to different solar irradiance and ambient temperature profiles (also referred to as mission profiles). In fact, the installation site also affects the degradation rate of the PV panels, and thus long-term energy production...... and reliability. Prior-art lifetime analysis in PV inverters has not yet investigated the impact of PV panel degradations. This paper thus evaluates the lifetime of PV inverters considering panel degradation rates and mission profiles. Evaluations have been carried out on PV systems installed in Denmark...... and Arizona. The results reveal that the PV panel degradation rate has a considerable impact on the PV inverter lifetime, especially in the hot climate (e.g., Arizona), where the panel degrades at a faster rate. In that case, the PV inverter lifetime prediction can be deviated by 54%, if the impact of PV...

The United States Department of Energy (DOE) awarded a grant to GL Garrad Hassan (GL GH) to investigate the logistics, opportunities, and costs associated with existing and emerging installation and operation and maintenance (O&M) activities at offshore wind projects as part of the DOE’s program to reduce barriers facing offshore wind project development in the United States (U.S.). This report (the Report) forms part of Subtopic 5.3 “Optimized Installation, Operation and Maintenance Strategies Study” which in turn is part of the “Removing Market Barriers in U.S. Offshore Wind” set of projects for the DOE. The purpose of Subtopic 5.3 is to aid and facilitate informed decision-making regarding installation and O&M during the development, installation, and operation of offshore wind projects in order to increase efficiency and reduce the levelized cost of energy (LCoE). Given the large area of U.S. territorial waters, the generally higher mean wind speeds offshore, and the proximity to the coast of many large U.S. cities, offshore wind power has the potential to become a significant contributor of energy to U.S. markets. However, for the U.S. to ensure that the development of offshore wind energy projects is carried out in an efficient and cost-effective manner, it is important to be cognizant of the current and emerging practices in both the domestic and international offshore wind energy industries. The U.S. can harness the experience gained globally and combine this with the skills and assets of an already sizeable onshore wind industry, as well as the resources of a mature offshore oil and gas industry, to develop a strong offshore wind sector. The work detailed in this report is aimed at assisting with that learning curve, particularly in terms of offshore specific installation and O&M activities. This Report and the Installation and O&M LCoE Analysis Tool, which were developed together by GL GH as part of this study, allow readers to identify, model

Solar Adoption and Energy Consumption in the Residential Sector

Science.gov (United States)

McAllister, Joseph Andrew

This dissertation analyzes the energy consumption behavior of residential adopters of solar photovoltaic systems (solar-PV). Based on large data sets from the San Diego region that have been assembled or otherwise acquired by the author, the dissertation quantifies changes in energy consumption after solar-PV installation and determines whether certain household characteristics are correlated with such changes. In doing so, it seeks to answer two related questions: First, "Do residential solar adopters increase or decrease their electricity consumption after they install a solar-PV system?" Assuming that certain categories of residential adopters increase and others decrease, the second question is "Which residential adopters increase and which decrease their consumption and why?" The database that was used to conduct this analysis includes information about 5,243 residential systems in San Diego Gas & Electric's (SDG&E) service territory installed between January 2007 and December 2010. San Diego is a national leader in the installation of small-scale solar-electric systems, with over 12,000 systems in the region installed as of January 2012, or around 14% of the total number installed in California. The author performed detailed characterization of a significant subset of the solar installations in the San Diego region. Assembled data included technical and economic characteristics of the systems themselves; the solar companies that sold and installed them; individual customer electric utility billing data; metered PV production data for a subgroup of these solar systems; and data about the properties where the systems are located. Primarily, the author was able to conduct an electricity consumption analysis at the individual household level for 2,410 PV systems installed in SDG&E service territory between January 2007 and December 2010. This analysis was designed to detect changes in electricity consumption from the pre-solar to the post-installation period. To

Mortimore, J.A.; Lee, T.A.

1994-09-01

This report documents the drilling and installation of 11 groundwater quality monitoring (GQM) wells on the perimeter of Lower Waste Area Grouping (WAG) 2. Lower WAG 2 consists of White Oak Lake and the embayment below White Oak Dam above the Clinch River. The wells in Lower WAG 2 were drilled and developed between December 1989 and September 1990. These wells were installed to characterize and assess the WAG in accordance with applicable Department of Energy, state, and Environmental Protection Agency regulatory requirements. The wells at Lower WAG 2 were drilled with auger or air rotary rigs. Depending on the hydrogeologic conditions present at each proposed well location, one of three basic installation methods was utilized. Detailed procedures for well construction were specified by the Engineering Division to ensure that the wells would provide water samples representative of the aquifer. To ensure conformance with the specifications, Energy Systems Construction Engineering and ERCE provided continuous oversight of field activities. The purpose of the well installation program was to install GQM wells for groundwater characterization at Lower WAG 2. Data packages produced during installation activities by the ERCE hydrogeologists are an important product of the program. These packages document the well drilling, installation, and development activities and provide valuable data for well sampling and WAG characterization. The forms contained in the packages include predrilling and postdrilling checklists, drilling and construction logs, development and hydraulic conductivity records, and quality control-related documents

On Orientation Control of Suspended Blade During Installation in Wind Turbines

DEFF Research Database (Denmark)

Schmidt, Lasse; Roemer, Daniel Beck; Pedersen, Henrik Clemmensen

2015-01-01

This paper discusses problems involved in the procedure for offshore installation of blades in wind turbines, due to wind loads. In general the high winds at sea provides for nearly optimal conditions for harvesting energy via wind turbines due to the often high wind speeds and low turbulence...... intensity. However, the very same features also call for great difficulties during installation of the wind turbine blades, making this process extremely difficult, expensive and time consuming. Often the blades are hoisted to the wind turbine hub via cranes and sought held in appropriate positions by so......-called taglines/wires, but still significant motion oscillations of blade root ends are experienced, even at rather low wind speeds. The paper considers the possibility to dampen the oscillating motions via control of the tagline lengths. The main control strategy considered, is the possibility to control...

The Current Situation of Wind Energy in Turkey

Directory of Open Access Journals (Sweden)

Raşit Ata

2013-01-01

Full Text Available Wind energy applications and turbine installations at different scales have increased since the beginning of this century. As wind energy is an alternative clean energy source compared to the fossil fuels that pollute the atmosphere, systems that convert wind energy to electricity have developed rapidly. Turkey’s domestic fossil fuel resources are extremely limited. In addition, Turkey’s geographical location has several advantages for extensive use of wind power. In this context, renewable energy resources appear to be one of the most efficient and effective solutions for sustainable energy development and environmental pollution prevention in Turkey. Among the renewable sources, Turkey has very high wind energy potential. According to the Organization for Economic Cooperation and Development (OECD Turkey theoretically has 166 TWh a year of wind potential. However the installed wind power capacity is approximately 14% of total economical wind potential. In this study, Turkey’s installed electric power capacity and electric energy production are investigated and also the current situation of wind energy in Turkey is examined. The wind data used in this study were taken from Turkish Wind Energy Association (TUREB for the year 2012. This paper reviews the assessment of wind energy in Turkey as of the end of July 2012 including wind energy applications.

TWO-STAGE HEAT PUMPS FOR ENERGY SAVING TECHNOLOGIES

Directory of Open Access Journals (Sweden)

A. E. Denysova

2017-09-01

Full Text Available The problem of energy saving becomes one of the most important in power engineering. It is caused by exhaustion of world reserves in hydrocarbon fuel, such as gas, oil and coal representing sources of traditional heat supply. Conventional sources have essential shortcomings: low power, ecological and economic efficiencies, that can be eliminated by using alternative methods of power supply, like the considered one: low-temperature natural heat of ground waters of on the basis of heat pump installations application. The heat supply system considered provides an effective use of two stages heat pump installation operating as heat source at ground waters during the lowest ambient temperature period. Proposed is a calculation method of heat pump installations on the basis of groundwater energy. Calculated are the values of electric energy consumption by the compressors’ drive, and the heat supply system transformation coefficient µ for a low-potential source of heat from ground waters allowing to estimate high efficiency of two stages heat pump installations.

On the physics of power, energy and economics of renewable electric energy sources - Part II

International Nuclear Information System (INIS)

Skoglund, Annika; Leijon, Mats; Waters, Rafael; Rehn, Alf; Lindahl, Marcus

2010-01-01

Renewable Energy Technologies (RETs) are often recognized as less competitive than traditional electric energy conversion systems. Obstacles with renewable electric energy conversion systems are often referred to the intermittency of the energy sources and the relatively high maintenance cost. However, due to an intensified discourse on climate change and its effects, it has from a societal point of view, become more desirable to adopt and install CO 2 neutral power plants. Even if this has increased the competitiveness of RETs in a political sense, the new goals for RET installations must also be met with economical viability. We propose that the direction of technical development, as well as the chosen technology in new installations, should not primarily be determined by policies, but by the basic physical properties of the energy source and the associated potential for inexpensive energy production. This potential is the basic entity that drives the payback of the investment of a specific RET power plant. With regard to this, we argue that the total electric energy conversion system must be considered if effective power production is to be achieved, with focus on the possible number of full loading hours and the Degree of Utilization. This will increase the cost efficiency and economical competitiveness of RET investments, and could enhance faster diffusion of new innovations and installations without over-optimistic subsidies. This paper elaborates on the overall problem of the economy of renewable electric energy conversion systems by studying the interface between physics, engineering and economy reported for RET power plants in different scientific publications. The core objective is to show the practical use of the Degree of Utilization and how the concept is crucial for the design and economical optimization disregarding subsidies. The results clearly indicate that the future political regulative frameworks should consider the choice of renewable energy

A novel method for coiled tubing installation

Energy Technology Data Exchange (ETDEWEB)

Simpson, Peter J. [2H Offshore, Houston, TX (United States); Tibbetts, David [Aquactic Engineering and Construction Ltd., Aberdeen (United Kingdom)

2009-12-19

Installation of flexible pipe for offshore developments is costly due to the physical cost of the flexible pipe, expensive day rates and the availability of suitable installation vessels. Considering the scarcity of flexible pipe in today's increasingly demanding and busy market, operators are seeking a cost effective solution for installing piping in a range of water depths using vessels which are readily on hand. This paper describes a novel approach to installing reeled coiled tubing, from 1 inch to 5 inch diameter, from the back of a small vessel in water depths from 40 m up to around 1000 m. The uniqueness of the system is the fact that the equipment design is modular and compact. This means that when disassembled, it fits into standard 40 ft shipping containers, and the size allows it to be installed on even relatively small vessels of opportunity, such as anchor handling or installation vessels, from smaller, and cheaper quay side locations. Such an approach is the ideal solution to the problem faced by operators, in that it allows the installation of cheaper, readily available coiled tubing, from cost-effective vessels, which do not need to transit to a pick up the system.

Accelerating Ocean Energy to the Marketplace – Environmental Research at the U.S. Department of Energy National Laboratories

Energy Technology Data Exchange (ETDEWEB)

Copping, Andrea E.; Cada, G. F.; Roberts, Jesse; Bevelhimer, Mark

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.

Lessons learned from installation of an environmental horizontal well

International Nuclear Information System (INIS)

Oakley, D.B.; Nickelson, M.D.

1994-01-01

At Williams Air Force Base near Phoenix, Arizona, a Pilot Study/Demonstration Study is being performed to evaluate the effectiveness of horizontal vs vertical wells in remediating and containing a jet fuel contaminant plume. An early stage of this project included successful installation of the world's longest, deepest environmental horizontal well. The horizontal well was installed using river crossing technology developed for drilling boreholes and installing utility conduits under rivers. Boreholes more than 5,000 ft. long have been successfully installed using river crossing technology. However, these boreholes are typically shallower than 100 ft. below land surface. Installation of the environment horizontal well proved to be extremely challenging because of the depth, the length of the borehole, and the requirements dictated by well installation criteria. Two installation attempts failed before the successful installation. The first installation attempt failed during well material installation. The second attempt resulted in the drill string becoming permanently stuck and abandoned downhole. The history of the two failed and one successful installation attempts demonstrates several lessons learned, including (1) streamline the well materials installation process as much as possible; (2) guar-gum-based drilling muds do not have the gel strength to remove sufficient cuttings from deep boreholes; (3) if sandpack around the well screen is required, a prepack screen should be installed--avoid using tremie pipes for installing a sandpack; (4) drill string location information provided by surface magnetic systems is unreliable at 150 ft. or more bls; and (5) for difficult drilling conditions, 24 hr./day drilling is recommended

World supply of nuclear energy

International Nuclear Information System (INIS)

Pecqueur, Michel.

1981-01-01

At the end of 1980 nuclear energy accounted for 9% of the world production of electricity stemming from 262 power stations, utilising mainly the process of water reactors and representing an installed capacity of 142 GWe. This production, apparently limited, already represents the equivalent of 150 million TOE. The 600 nuclear power stations in service, under construction or ordered represent a total of 450 GWe. In 1985, their production ought to cover 15% of the world requirements of electricity, which corresponds to a doubling of the share of nuclear energy within 6 years. During these recent years, the development of nuclear energy has undergone a significant slowing down and the number of orders for new nuclear power stations has dropped considerably in particular in the United States. Considering the time required and the available industrial capacity, the accumulated capacity which could be installed worlwide by 1990 could attain 530 GWe, equivalent to 650 MTOE covering 24% of the world production of electricity and 7% of the world consumption of primary energy. A determined effort for the end of this century could end up by the installation of 1200 GWe of capacity, generating 1.5 GTOE. The share of nuclear energy would then represent 35% of the production of electricity [fr
