    This report discusses the potential for reducing the use of energy and quantifies the environmental disadvantages and estimated environmental costs of various energy carriers in Norway. The MARKAL model is used to work out three scenarios for a more sustainable use of energy. It is found that the environmental impact of NOx emissions are much greater than that of sulfur emissions. The damage caused by CO2 and NOx are of the same order of magnitude. The studies indicate that if the damage to the environment is internalized into the energy system, then it will lead to increased use of gas in the industry and transport sectors. The results are sensitive with respect to the cost development for the cleaning technology of conventional energy carriers and for storage and transport of gas. Internalizing the external costs is not enough to eliminate the environmental damage, at least not as this is valued today and with the technology supposed to be available for the next 30-40 years.

  2. Sustainable development and energy supply

    'Sustainable' is an old established term which has made a political career in the past ten years. The roots of this career extend back into the 18th century, when an economic concept of forest management was developed to replace yield maximization achieved by means of complete deforestation by yield optimization attained by conservative forest management. This latter type of forest management was termed 'sustainable'. The language used in today's sustainability debate was based on the idea of preserving the capital provided by nature and living on the interest. As a consequence, the term 'sustainable' became one of the key points in environmental policy and economic policy after the Brundtland report had been published (V. Hauff, 1987), which also constitutes the background to this article. (orig.) [de

    Agenda 21 formulated in connection with the UN-Summit in Rio de Janeiro summarises the demands and suggestions concerning a sustainable energy use and energy supply: 'Energy is essential to economic and social development and improved quality of life. Much of the world's energy, however, is currently produced and consumed in ways that could not be sustained if technology were to remain constant and if overall quantities were to increase substantially.' Since the adoption of Agenda 21 the energy issue has been at the centre of the Rio process, either directly, if aspects of supply for humans are concerned, or indirectly, if the anthropogenic greenhouse effect is dealt with. Germany takes an active role in participating in the Rio process, adopting it to national conceptions and supporting other countries on their path to Sustainable Development. Milestones of the German Rio Process are the commitment to the goals and actions of the Rio Declaration and the Agenda 21 as well to the corresponding UN conventions. The German Federal Government has taken several actions. In summer 2000 the Federal Cabinet adopted a bill according to which a Council for Sustainable Development (Nachhaltigkeitsrat) was to be instituted at the beginning of 2001. The Council's task is to participate in the development and formulation of a sustainability strategy for the Federal Republic of Germany. Furthermore, the Federal Government has agreed on the institution of a State Secretary Committee for Sustainable Development. The Committee's task is among other things to define concrete projects for the implementation of the federal sustainable strategy. (BA)

    Schilling, H.D.

    2000-01-01

    Is the concept of sustainable development really a new concept of our times? The answer given by the author is 'no'. He explains the roots of this concept by referring to the energy conservation principle discovered in 1845 by Robert Meyer (1st law of thermodynamics), and to Rudolf Clausius who, in 1850, formulated the 2nd law of thermodynamics which was to become one of the most important scientific achievements of the 19th century. The author continues the brief historical survey of scientific knowledge and application of the energy conservation principle in connection with input-output systems in the broadest sense, and particularly in energy engineering. The second part of the paper deals with the recent past, advances in science and technology and the technology-ecology nexus, as well as social, educational and economic aspects of relevance in our time, including a look at future challenges.

    The right energy mix is decisive. The European Commission feels that nuclear power can make an important contribution towards sustainable energy supply in Europe. Nuclear power should keep its place in the European energy mix. One important aspect in this regard is improved public acceptance through communication, transparency, and confidence building. High safety standards and a credible approach to the safe long-term management of radioactive waste are major components of this sustainable energy source. (orig./GL)

    Modern society is dependent on fossil fuels for its energy needs, but their combustion is producing emissions of greenhouse gases that cause global warming. If these emissions remain unconstrained they risk of producing significant impacts on humanity and ecosystems. Replacement of fossil fuels with alternative energy sources can stabilize anthropogenic global warming and thus reduce the climate change impacts. The deployment of alternative energy supply technologies should be based on objectives that are consistent with sustainability indicators and incorporate quantitative risk assessment multiattribute utility decision methodologies capable of ascertaining effective future energy supply options.

    2002-01-01

    From this overall concept of what constitutes sustainability, a range of considerations on equity of energy supply across regions, time scales over which fuel and energy source mixes and technology changes and the like, can be developed. Within the spatial dimension, considerations of sustainability that operate at the global scale need to be translated to the operations of large and small companies, national and local governments down to individual households. It is a complex mix in an increasingly complex world. But one thing is certain, the world's energy demand is going to continue to increase. This demand will be largely satisfied by fossil fuels and this use is not sustainable using current technology in the long term. Massive changes are required to turn the world around onto a more sustainable pathway that will probably take many decades even to make a significant start. The aim of this paper is to briefly explore some of the possible technological options that will guide us on the road to a more sustainable energy future. A genuinely sustainable energy system that also promotes sustainable growth with an improving standard of living for all is obviously a major challenge. At the same time the global demand for energy will continue to increase. On the global scale, the prospect of climate change imposes a major long-term constraint on the use of GHG emitting fuels and generating technologies. The long-term development of a sustainable energy system will require multiple interventions and a pluralistic approach to energy management. Ingredients within the mix are likely to require: 1. innovation in the way we currently generate and supply power 2. continued integration and greater penetration of renewables 3. greater use of embedded and distributed energy generation 4. aggressive end-use efficiency 5. development of technologies to enable continued use of fossil fuels until the transition to sustainability is completed. A combination of market and regulatory

    The main objectives of this study are, first, to determine the sustainable energy strategies for green energy supply, and secondly, to derive the green energy recovery ratio and the sustainable green energy progress ratio, and thirdly, to investigate the effects of sustainable energy strategies on these ratios. For these purposes, 20-possible sustainable energy strategies are taken into consideration and are divided into three subgroups that are strategies on the technological impact, sectoral impact, and green energy impact in a society. Using the possible sustainable energy strategies, technological and sectoral impact ratios of green energy and also green energy activity ratio are determined and discussed in detail. Additionally, some Case studies are performed in the scope of this interesting investigation: (i) the effect of technological impact ratio on green energy recovery ratio, and sustainable green energy progress ratio, (ii) the effect of sectoral impact ratio on green energy recovery ratio, and sustainable green energy progress ratio, and (iii) the effect of green energy impact ratio on green energy recovery ratio and sustainable green energy progress ratio. It is found that sustainable green energy progress ratio increases with an increase of technological, sectoral, and green energy impact ratios. This means that all negative effects on the industrial, technological, sectoral and social developments partially and/or completely decrease throughout the transition and utilization to and of green energy and technologies when possible sustainable energy strategies are preferred and applied. Thus, the sustainable energy strategies can make an important contribution to the economies of the countries where green energy is abundantly produced. Therefore, the investment in green energy supply should be, for the future of world nations, encouraged by governments and other authoritative bodies who, for strategic reasons, wish to have a green alternative to fossil

    Xie, Fei

    This dissertation aims at modeling sustainability of renewable fuel supply chain systems against emerging challenges. In particular, the dissertation focuses on the biofuel supply chain system design, and manages to develop advanced modeling framework and corresponding solution methods in tackling challenges in sustaining biofuel supply chain systems. These challenges include: (1) to integrate "environmental thinking" into the long-term biofuel supply chain planning; (2) to adopt multimodal transportation to mitigate seasonality in biofuel supply chain operations; (3) to provide strategies in hedging against uncertainty from conversion technology; and (4) to develop methodologies in long-term sequential planning of the biofuel supply chain under uncertainties. All models are mixed integer programs, which also involves multi-objective programming method and two-stage/multistage stochastic programming methods. In particular for the long-term sequential planning under uncertainties, to reduce the computational challenges due to the exponential expansion of the scenario tree, I also developed efficient ND-Max method which is more efficient than CPLEX and Nested Decomposition method. Through result analysis of four independent studies, it is found that the proposed modeling frameworks can effectively improve the economic performance, enhance environmental benefits and reduce risks due to systems uncertainties for the biofuel supply chain systems.

    introduction of climate change prevention measures. However, the general public and particularly politicians of many countries are set against nuclear power (both the existing and new reactors), and some even use law mechanisms to ban any activity in that respect. Since nuclear power has thus been a political issue for too long, now a mature and a more realistic approach is needed to the nuclear energy in terms of security of supply, as well as of the market competitiveness and sustainable development. A very important contribution is made by nuclear in terms of the avoidance of greenhouse gas emissions. If the existing nuclear plants were phased out and replaced with other conventional generating plant, it would be impossible to achieve the Kyoto objectives. Although the use of nuclear power instead of burning fossil fuels to generate electricity makes a significant contribution to reducing electricity-related CO 2 emissions, it is nevertheless often criticized on the grounds of the radioactive waste it produces. Radioactive waste is an issue where the technical solutions most definitely exist and further research is also being continued on the development of possible alternative solutions, but for the implementation of these solutions, a more and better communication is necessary to obtain consensus and political acceptance. Existing nuclear power stations are very cheap to run. Once the capital costs have been incurred, there are therefore huge economic advantages in keeping them going for their full lifespan. The existing reactor units in Europe produce electricity at a cost of between 1.6 and 1.9 cents per kWh, compared with 2.5-2.7 cents per kWh for plants that burn natural gas. The decision for a premature closure of the existing stations faced in Sweden and in Germany, is not only a waste of an important capital resource, but it requires a switch to alternative generation that may produce power at much higher costs, and in the same time is likely to have a worse

    Full Text Available The design of future agricultural production systems requires innovative approaches. For creating a more productive, resource-efficient and low-emission agriculture the systemic development of the agricultural processes, the operating conditions and the organizational processes is necessary. Fundamentally new approaches can be found by defining scenarios. Such a hypothetic concept does field operation without using internal combustion engines. Instead of this the power supply of performant machines can be done by electric direct supply systems or for small machines by battery systems with charging points. However, all this requires the electrical energy supply of agricultural fields. A direct electric energy supply utilizing the Center Pivot approach via rotating structures enables new production systems. Using innovative technologies new solutions with great potential for automation and a productive precision agriculture can be designed. This paper highlights an unconventional approach stimulating the discussion about future developments in agricultural engineering.

    Full Text Available The increasing demand for energy and expected shortage in the medium term, solicit innovative energy strategies to fulfill the increasing gap between demand-supply. For this purpose it is important to evaluate the potential supply of the energy crops and finding the areas of EU where it is most convenient. This paper proposes an agro-energy supply chain approach to planning the biofuel supply chain at a regional level. The proposed methodology is the result of an interdisciplinary team work and is aimed to evaluate the potential supply of land for the energy production and the efficiency of the processing plants considering simultaneously economic, energy and environmental targets. The crop simulation, on the basis of this approach, takes into account environmental and agricultural variables (soil, climate, crop, agronomic technique that affect yields, energy and economic costs of the agricultural phase. The use of the Dijkstra’s algorithm allows minimizing the biomass transport path from farm to collecting points and the processing plant, to reduce both the transport cost and the energy consumption. Finally, a global sustainability index (ACSI, Agro-energy Chain Sustainability Index is computed combining economic, energy and environmental aspects to evaluate the sustainability of the Agroenergy supply chain (AESC on the territory. The empirical part consists in a pilot study applied to the whole plain of Friuli Venezia Giulia (FVG a region situated in the North-Eastern part of Italy covering about 161,300 ha. The simulation has been applied to the maize cultivation using three different technologies (different levels of irrigation and nitrogen fertilization: low, medium and high input. The higher input technologies allow to achieve higher crop yields, but affect negatively both the economic and energy balances. Low input levels provides, on the average, the most favourable energy and economic balances. ACSI indicates that low inputs levels

    Following the lead of the European Union in introducing binding measures to promote the use of regenerative energy forms, it is not unreasonable to assume that the global demand for combustible raw materials for energy generation will be reduced considerably in the second half of this century. This will not only have a favourable effect on the CO(2) concentration in the atmosphere, but will also help preserve fossil fuels-important as raw materials in the chemical industry-for future generations. Nevertheless, associated with the concomitant massive shift to regenerative energy forms, there will be a strong demand for other exhaustible raw materials, in particular metals, some of which are already regarded as scarce. After reviewing the debate on mineral depletion between "cornucopians" and "pessimists", we discuss the meaning of mineral "scarcity", particularly in the geochemical sense, and mineral "exhaustion". The expected drastic increase in demand for mineral resources caused by demographic and societal pressures, that is, due to the increase in in-use stock, is emphasised. Whilst not discussing the issue of "strong" versus "weak" sustainability in detail, we conclude that regenerative energy systems-like nearly all resource-consuming systems in our society-do not necessarily satisfy generally accepted sustainability criteria. In this regard, we discuss some current examples, namely, lithium and cobalt for batteries, rare earth-based permanent magnets for wind turbines, cadmium and tellurium for solar cells and copper for electrical power distribution.

  18. Towards a sustainable global energy supply infrastructure: Net energy balance and density considerations

    Kessides, Ioannis N.; Wade, David C.

    2011-01-01

    This paper employs a framework of dynamic energy analysis to model the growth potential of alternative electricity supply infrastructures as constrained by innate physical energy balance and dynamic response limits. Coal-fired generation meets the criteria of longevity (abundance of energy source) and scalability (ability to expand to the multi-terawatt level) which are critical for a sustainable energy supply chain, but carries a very heavy carbon footprint. Renewables and nuclear power, on the other hand, meet both the longevity and environmental friendliness criteria. However, due to their substantially different energy densities and load factors, they vary in terms of their ability to deliver net excess energy and attain the scale needed for meeting the huge global energy demand. The low power density of renewable energy extraction and the intermittency of renewable flows limit their ability to achieve high rates of indigenous infrastructure growth. A significant global nuclear power deployment, on the other hand, could engender serious risks related to proliferation, safety, and waste disposal. Unlike renewable sources of energy, nuclear power is an unforgiving technology because human lapses and errors can have ecological and social impacts that are catastrophic and irreversible. Thus, the transition to a low carbon economy is likely to prove much more challenging than early optimists have claimed. - Highlights: → We model the growth potential of alternative electricity supply infrastructures. → Coal is scalable and abundant but carries a heavy carbon footprint. → Renewables and nuclear meet the longevity and environmental friendliness criteria. → The low power density and intermittency of renewables limit their growth potential. → Nuclear power continues to raise concerns about proliferation, safety, and waste.

    2014-12-01

    The Kamojang Geothermal Field (KGF) is a typical vapor dominated hydrothermal system in West Java, Indonesia. This geothermal field is the oldest exploited geothermal field in Indonesia. From 1983 to 2005, more than 160 million tons of steam have been exploited from the KGF and more than 30 million tons of water were injected into the reservoir system. The injected water come from condensed water, local river and ground water. Sustainable production in the geothermal energy development is the ability of the production system applied to sustain the stable production level over long times and to manage the mass balance between production, injection and natural recharge in the geothermal reservoir during exploitation. Mass balance in the reservoir system can be monitored by using time lapse gravity monitoring. Mass variation of hydrodynamic in the reservoir of KGF from 1999 to 2005 is about -3.34 Mt/year while is about -3.78 Mt/year from 1999 to 2008. Another period between 2009 and 2010, mass variation decreased about -8.24 Mt. According to the history of production and injection, natural recharge to the KGF's reservoir is estimated at about 2.77 Mt/year from 1999 to 2005 and 2.75 Mt/year from 1999 to 2008. Between 2009 and 2010, KGF has a bigger mass deficiency rate throughout 200 MWe maintain production. Large amount of fresh water is needed for sustainable geothermal energy production, while the domestic water supply need is also increased. Natural recharge, about 50% of injected water, cooling system, drilling and other production activities in KGF spend large amounts of fresh water. Water consumption for local people around KGF is about 1.46 MT/year. The water volume around KGF of total runoff is the range between dry season 0.07 MT/month and rainy season 4.4 MT/month. The water demands for sustainable geothermal production of KGF and for local people's consumption will increase in the future. Integrated planning between the energy and water sectors in KGF

    'Sustainable development' is the guiding principle of the ecological, economic and development policy debate. Although the guiding principle of 'sustainable development' meets with unanimous approval as a general rule, there is a broad spectrum of views and interpretations of this guiding principle in terms of its normative and theoretical scientific basis as well as with regard to the aims and line of action to be taken. This applies especially to the energy sector. This lecture endeavours to concretise the guiding principle of 'sustainable development' for the energy sector, or to put in more exact terms, for the sector providing energy services. Major options for the supply of energy are classified and evaluated in terms of their importance for the sustainable provision of energy based on the results of a comprehensive review of materials and different types of energy.

  5. Evaluating the sustainability of an energy supply system using renewable energy sources: An energy demand assessment of South Carolina

    Green, Cedric Fitzgerald

    Sustainable energy is defined as a dynamic harmony between the equitable availability of energy-intensive goods and services to all people and the preservation of the earth for future generations. Sustainable energy development continues to be a major focus within the government and regulatory governing bodies in the electric utility industry. This is as a result of continued demand for electricity and the impact of greenhouse gas emissions from electricity generating plants on the environment by way of the greenhouse effect. A culmination of increasing concerns about climate change, the nuclear incident in Fukushima four years ago, and discussions on energy security in a world with growing energy demand have led to a movement for increasing the share of power generation from renewable energy sources. This work studies demand for electricity from primarily residential, commercial, agricultural, and industrial customers in South Carolina (SC) and its effect on the environment from coal-fired electricity generating plants. Moreover, this work studies sustainable renewable energy source-options based on the renewable resources available in the state of SC, as viable options to supplement generation from coal-fired electricity generating plants. In addition, greenhouse gas emissions and other pollutants from primarily coal-fired plants will be defined and quantified. Fundamental renewable energy source options will be defined and quantified based on availability and sustainability of SC's natural resources. This work studies the environmental, economic, and technical aspects of each renewable energy source as a sustainable energy option to replace power generation from coal-fired plants. Additionally, social aspect implications will be incorporated into each of the three aspects listed above, as these aspects are explored during the research and analysis. Electricity demand data and alternative energy source-supply data in SC are carried out and are used to develop and

    Sustainable energy supply must do justice to the equal-ranking goals of economic, environmental and social compatibility. A balance must be sought between the degrees of achievement for these aims. In climate protection, approaches must be pursued that promise achievement at the lowest cost. An approximation of energy-management development to climate-policy necessities is only possible if all cost-efficient options are used. CCS can be regarded as a bridging technology toward an energy sector that is increasingly based almost entirely on electricity from renewables. On the road there, the expansion of renewables and power generation based on fossil energies with CCS complement one another.

    The provision of electricity is of central importance for economic growth and societal development. While numerous societal and economic benefits arise from the use of electricity, the production of electricity can also have negative impacts on the environment and the climate system. The commitment to sustainable development calls for the evaluation of the extent to which the different electricity supply options fulfill the sustainability criteria. The conceptual framework of Life Cycle Assessment (LCA) can provide a solid basis for a comparative assessment of different electricity supply options with regard to their environmental impacts, raw material requirements as well as their resulting external costs. Results of a comprehensive comparative assessment of nuclear energy and other electricity options are presented. (author)

    Bals, Lydia; Tate, Wendy

    A significant conceptual and practical challenge is how to integrate triple bottom line (TBL; including economic, social and environmental) sustainability into global supply chains.

    Energy supply to the rural poor in developing countries is a complex activity that transcends the simple selection of a best technology. This paper explains the outcomes achieved by using a new multi-criteria decision-support system to assist in calculating the most appropriate set of energy options for providing sufficient power to fulfil local demands that improve livelihoods. The elicitation of the priorities of future users, which are subsequently integrated into the energy selection process, is seen as a mechanism for the promotion of energy policies that ensure that technological developments reduce poverty. The sustainable rural energy decision support system (SURE DSS), a methodological package and software designed by the research team RESURL builds upon technical and non-technical features of energy development in remote poor areas, drawing on a sustainable livelihoods approach as part of its rationale. SURE enables simulations and calculation of the disparities that may arise between current and potential livelihoods after specific energy solutions have been installed, as well as measuring potential trade-offs among alternative livelihoods. The paper reports the outcome of an application of SURE to the case of a remote Colombian rural community whose total energy demands are only partly met through a diesel generator

    Full Text Available Paper describes and analyses new and innovative concept for possible integration of solar photovoltaic (PV energy in urban water supply system (UWSS. Proposed system consists of PV generator and invertor, pump station and water reservoir. System is sized in such a manner that every his part is sized separately and after this integrated into a whole. This integration is desirable for several reasons, where the most important is the achievement of the objectives of sustainable living in urban areas i.e. achieving of sustainable urban water supply system. The biggest technological challenge associated with the use of solar, wind and other intermittent renewable energy sources RES is the realization of economically and environmentally friendly electric energy storage (EES. The paper elaborates the use of water reservoires in UWSS as EES. The proposed solution is still more expensive than the traditional and is economically acceptable today in the cases of isolated urban water system and special situations. Wider application will depend on the future trends of energy prices, construction costs of PV generators and needs for CO2 reduction by urban water infrastructure.

    Options available for improving energy efficiency in the Netherlands are listed and discussed. As detailed in this report, there is still substantial scope for reducing energy consumption in the production and use of energy carriers, much of it not only attractive from the perspective of society as a whole but also profitable for the actors concerned. By exploiting these opportunities, sustainability targets can be cost-effectively met. The report examines why so much potential is still not being utilised and how this can be remedied. Following a description of the potential for energy conservation, a package of smart, effective policies is recommended to secure this potential [Dutch] De mogelijkheden van energiebesparing in Nederland zijn in kaart gebracht. In deze notitie wordt aangetoond dat bij energiebesparing bij het gebruik en bij de productie van energiedragers nog veel onbenut, maar maatschappelijk aantrekkelijk potentieel ligt, waarvan een groot deel rendabel is. Benutting daarvan leidt ertoe dat de duurzaamheidsdoelen op een kosteneffectieve manier behaald kunnen worden. We hebben onderzocht waarom veel potentieel nu niet benut wordt en hoe dat wel kan gebeuren. Deze analyse beschrijft het besparingspotentieel en biedt voorstellen voor een pakket aan slimme, effectieve beleidsinstrumenten om dit potentieel te realiseren: door inzet van verplichtingen en door energiebesparing aantrekkelijker te maken.

    Highlights: • We discussed uranium resources with an energy security perspective. • We concluded seawater uranium is preferable for sustainability and energy security. • We evaluated electricity generation cost of seawater uranium fueled HTGR. • We concluded electricity generation with seawater uranium is reasonable. - Abstract: Sustainable and safe energy supply with High Temperature Gas-cooled Reactor (HTGR) fueled by uranium from seawater have been investigated and discussed. From the view point of safety feature of self-regulation with thermal reactor of HTGR, the uranium resources should be inexhaustible. The seawater uranium is expected to be alternative resources to conventional resources because it exists so much in seawater as a solute. It is said that 4.5 billion tons of uranium is dissolved in the seawater, which corresponds to a consumption of approximately 72 thousand years. Moreover, a thousand times of the amount of 4.5 trillion tU of uranium, which corresponds to the consumption of 72 million years, also is included in the rock on the surface of the sea floor, and that is also recoverable as seawater uranium because uranium in seawater is in an equilibrium state with that. In other words, the uranium from seawater is almost inexhaustible natural resource. However, the recovery cost with current technology is still expensive compared with that of conventional uranium. Then, we assessed the effect of increase in uranium purchase cost on the entire electricity generation cost. In this study, the economy of electricity generation of cost of a commercial HTGR was evaluated with conventional uranium and seawater uranium. Compared with ordinary LWR using conventional uranium, HTGR can generate electricity cheaply because of small volume of simple direct gas turbine system compared with water and steam systems of LWR, rationalization by modularizing, and high thermal efficiency, even if fueled by seawater uranium. It is concluded that the HTGR

    2013-01-01

    Agriculture can simultaneously address global food, feed, fiber, and energy challenges provided our soil, water, and air resources are not compromised in doing so. Our objective is to present a landscape management concept as an approach for integrating multiple bio energy feedstock sources into current crop production systems. This is done to show how multiple, increasing global challenges can be met in a sustainable manner. We discuss how collaborative research among Usda-Agricultural Research Service (ARS), US Department of Energy (DOE) Idaho National Laboratory (INL), several university extension and research partners, and industry representatives [known as the Renewable Energy Assessment Project (Reap) team] has led to the development of computer-based decision aids for guiding sustainable bio energy feedstock production. The decision aids, known initially as the Corn Stover Tool and more recently as the Landscape Environmental Assessment Framework (Leaf) are tools designed to recognize the importance of nature s diversity and can therefore be used to guide sustainable feedstock production without having negative impacts on critical ecosystem services. Using a 57 ha farm site in central Iowa, USA, we show how producer decisions regarding corn (Zea mays L.) stover harvest within the US Corn Belt can be made in a more sustainable manner. This example also supports Reap team conclusions that stover should not be harvested if average grain yields are less than 11 Mg ha-1 unless more balanced landscape management practices are implemented. The tools also illustrate the importance of sub-field management and site-specific stover harvest strategies

    In February 2000, the German Bundestag established a Study Commission on 'Sustainable Energy Supplies in View of Globalisation and Liberalisation' (cf. Final Report, 2002). The Commission's Final Report is a contribution made by Germany toward implementing the sustainable development objectives defined in 1992 at the World Summit in Rio de Janeiro (Agenda 21). Despite minority votes of several members of the Study Commission, the main outcomes of the Final Report are worthwhile discussing in other industrial countries. The Commission had been given the mandate to identify 'robust, sustainable development paths' for the energy sector for the period up to 2050, which represent a scientific basis for the German parliament's further decision-making in the field of long-term energy policy. The applied backcasting approach showed that an ambitious climate-protection goal--reducing CO 2 emissions by 80% by 2050 - is technically and economically feasible. The main strategies and instruments for protecting the climate while ensuring a sustainable energy supply are summarised

    2008-02-27

    This paper reviews the opportunities available for food businesses to encourage consumers to eat healthier and more nutritious diets, to invest in more sustainable manufacturing and distribution systems and to develop procurement systems based on more sustainable forms of agriculture. The important factors in developing more sustainable supply chains are identified as the type of supply chain involved and the individual business attitude to extending responsibility for product quality into social and environmental performance within their own supply chains. Interpersonal trust and working to standards are both important to build more sustainable local and many conserved food supply chains, but inadequate to transform mainstream agriculture and raw material supplies to the manufactured and commodity food markets. Cooperation among food manufacturers, retailers, NGOs, governmental and farmers' organizations is vital in order to raise standards for some supply chains and to enable farmers to adopt more sustainable agricultural practices.

    The major challenge at the threshold of this century is to structure the energy supply in the sense of sustained development. The Committee of Enquiry of the Federal German Parliament 'Sustained energy supply under globalisation and liberalisation conditions' is developing medium to long-term concepts in this respect. Analysis of the boundary conditions of future energy policy shows that the consequences of future enrichment of climatic gases in the atmosphere and no longer the availability and productiveness of the energy deposits could become the limiting factor. Following the analysis of the technological and non-technological future potentials for sustained energy supply the Committee of Enquiry is currently working on the formulation of strategies for the energy industry transformation process.

    Full Text Available The development of decentralized renewable energy systems is of crucial importance for the decarbonization of energy generation worldwide. Purchase decisions regarding innovative energy systems depend to some extent on consumers’ perception of the systems’ degree of autarky. We assumed that, in addition to the energetic perspective, consumers associate other non-energetic facets such as independence, autonomy, self-sufficiency, or control with the concept of autarky. These psychological facets of autarky were expected to contribute to purchase decisions. In Study 1, participants (N = 168 evaluated three future energy supply scenarios. The scenarios varied regarding their range of autarky (household/neighborhood/small town, but the individually realized degree of energetic autarky did not vary. Participants reported a higher willingness to pay in connection with a higher perceived psychological autarky for the Household Scenario. Study 1’s findings were confirmed by Study 2, in which qualitative interviews (N = 13 also revealed that participants favored the Household Scenario on several points. These evaluations were driven by the anticipated psychological facets of autarky that is the subjective perception of being independent, autonomous, self-sufficient, energy secure, and of control. To promote an adoption of renewable energy systems, these psychological autarky facets need to be addressed. Enabling the people to self-determine, control, and secure their energy provision even in complex organizational settings in such a manner is likely to increase their acceptance and therefore foster the required social transition as a whole.

    Highlights: • Integration of carbon capture and sequestration and renewable resource technologies. • A new superstructure-based optimization model to identify the energy supply system. • Model validation via application study of the future transportation sector in Korea. - Abstract: In this study, a new design for a sustainable energy system was developed by integrating two technology frameworks: the renewable resource-based energy supply and the conventional (fossil fuel) resource-based energy production coupled with carbon capture and sequestration. To achieve this goal, a new superstructure-based optimization model was proposed using mixed-integer linear programming to identify the optimal combination of these technologies that minimizes the total daily cost, subject to various practical and logical constraints. The performance of the proposed model was validated via an application study of the future transportation sector in Korea. By considering six different scenarios that combined varying crude oil/natural gas prices and environmental regulation options, the optimal configuration of the energy supply system was identified, and the major cost drivers and their sensitivities were analyzed. It was shown that conventional resource-based energy production was preferred if crude oil and natural gas prices were low, even though environmental regulation was considered. Environmental regulation caused an increase in the total daily cost by an average of 26.4%, mainly due to CO 2 capture cost.

    Groundwater extracted in Research Centre for Soft Soil Malaysia (RECESS) contains a number of pollutants that exceed the safe level for consumption. A Solar-Hydro (S2H) model which is a practical prototype has been introduced to treat the groundwater sustainably by solar energy process (evaporation method). Selected parameters was tested which are sulphate, nitrate, chloride, fluoride, pH and dissolved oxygen. The water quality result shows that all parameters have achieved 100% of the drinking water quality standard issued by the Ministry of Health Malaysia. Evaporation method was proven that this solar energy can be applied in sustainably treating groundwater quality with up to 90% effectiveness. On the other hand, the quantitative analysis has shown that the production of clean water is below than 2% according to time constraints and design factors. Thus, this study can be generate clean and fresh water from groundwater by using a simplified model and it has huge potential to be implemented by the local communities with a larger scale and affordable design.

    2012-04-01

    In Europe, electrical power generation from renewable energy sources rose by about 50% in the last 20 years. In Germany, renewable electricity is mainly provided by wind power and photovoltaic. Energy output depends on weather conditions like wind speed or solar radiation and may therefore vary considerably. Rapid fluctuations in power generation already require regulation of conventional power plants by the distribution network operators to stabilize and ensure grid frequency and overall system stability. In order to avoid future blackouts caused by intermittent energy sources, it is necessary to increase the storage capacity for electric power. Theoretically, there are many technologies for storing energy, like accumulators, hydrogen storage systems, biomethane facilities (hydrocarbon synthesis) or compressed air storage. Only a few technologies combine sufficient capacity, fast response, high efficiency, low storage loss and long-term application experience. A pumped storage power plant (PSPP) is a state of the art technology which combines all of these aspects. Energy is stored in form of potential energy by pumping water to an upper reservoir in times of energy surplus or low energy costs. In times of insufficient power supply or high energy costs, the water is released through turbines to produce electric energy. The efficiency of state-of-the-art systems is about 70-80%. The total head (geodetic height between upper and lower reservoirs) and the storage capacity of the reservoirs as given in a mountainous terrain, determine the energy storage capacity of a PSPP. An alternative is the use of man-made geodetic height differences as given in ore, coal or open cast lignite mines. In these cases, the lower reservoir of the plant is located in the drifts or at the bottom of the mine. Energieforschungszentrum Niedersachsen (EFZN) has already explored the installation of a PSPP in abandoned ore mines in the Harz-region/Germany (Beck 2011). In 2011/2012 a basic

    The aim of the GeoSolCool research programme between the German Research Centre for Geoscience (GFZ) and The Research Council of Oman (TRC) is the development of an innovative and sustainable cooling system in combination with an aquifer thermal energy storage system in northern Oman. An integral part of this project is the design of a subsurface aquifer reservoir system for storage of thermal energy through hot water injection. An accurate characterisation of potential storage horizons is thus essential to ensure optimal efficiency of the cooling system. The study area, 40 km west of Muscat is characterised by a thick Cenozoic mixed carbonate-siliciclastic sedimentary succession, containing at least 3 aquifer horizons. We used a multidisciplinary approach for the initial ATES development phase, including geological fieldwork dovetailed with remote sensing analyses, thin-section analyses, geological modelling and reservoir fluid flow forecasting. First results indicate two potential storage horizons: (1) a Miocene-aged clastic-dominated alluvial fan system and (2) an Eocene carbonate sequence. The alluvial fan system is a more than 300 m thick, coarse clastic (mainly gravels and sandstones) succession of coalesced individual fans. Thin-section analyses showed that hydraulic parameters are favourable for the gravel and sandstone intervals but reservoir architecture is complex due to multiple generations of interconnecting fans with highly heterogeneous facies distributions. The Eocene carbonates were deposited in a carbonate ramp setting, strongly influenced by currents and storm events. Individual facies belts extend over kilometres and thus horizontal reservoir connectivity is expected to be good with minor facies variability. Thin-section analyses showed that especially the fossil-rich sections show good storage qualities. Fluid flow forecasting indicate that both potential horizons have good to very good storage characteristics. However, intense diagenetic

    Time and again the author has felt his adrenaline rise on listening to reports or talk shows in the media (radio, television, newspapers) that were based on nothing but misinformation and subjective sentiment. In this publication he has therefore endeavoured to give a popular scientific overview of the advantages of using wind power for the public energy supply. In the introduction he expresses his heart-felt thanks to the diploma'd journalist Anke Baars for her amiable support. The explanatory calculations are given as examples with the intention of clarifying the relationships and orders of magnitude involved. The numerical examples are presented with the intent of explaining target figures and assumptions. All information was collected through scrupulous research. The reader is encouraged to check on the numerical examples given. These have been presented to give a rough idea of the orders of magnitude and global relationships involved. This publication stands somewhat apart from the mainstream. The author hopes that the reader will gain instructive insights into the energy era, find food for thought and feel encouraged to participate and take action.

    Nuclear power construction planning study has already done by BATAN. The studies that cover various aspects have also done related to this preparation. The research centers in BATAN that have activities in energy application are directed to this preparation. This paper will generally describe the activities and result of the preparation study, especially related to technology aspect, site aspect, and social-economic impact. The preparation study has taken into account of some aspects, but still need updated and some more complementary study. The choice of technology will determine the ability for technology transfer. Industrial infrastructure and the design and engineering capability are the key role for self reliance in nuclear power technology. But the technology transfer will not succeed without government support. Muria Peninsula, precisely in Ujung Lemahabang has become the first candidate site, while Ujung Grenggengan and Ujung Watu as a second and third candidate sites. Though site could accommodate 7.000 MWe installed capacity, but are need to consider stability and capacity of transmission line to channeling the nuclear power out put in Jawa-Madura-Bali grid interconnection. From the economic impact aspect, nuclear power is competitive among other power plant system in order the role of nuclear power to give a solution in energy optimum mix policy and will reduce oil fuel consumption.

    Starting from the basic definition of sustainable development and its four dimensions, the role of indicators for sustainable energy development is analysed. In particular, it is shown that important energy efficiency indicators belong in fact to energy supply efficiency, while the end-use energy efficiency could be more pertinently represented by energy intensity indicators. Furthermore, the negentropic effects of science and technology related sustainable energy scenarios are pointed out. Finally, the sustainable development is related to wisdom, interpreted as a sum of knowledge, morality and timing. (Author)

    Coal is the main primary energy source in China. How to use coal cleanly and efficiently is the extremely important problem in China. Energy conservation and technology innovation are the key measures for mitigation of the pressure of energy supply. Import of energy (petroleum, LNG and high calorific coal) is inevitable. China has quite abundant energy resources, but the energy resource per capita is rather low. Because of the structure of industry and backwardness of technology, the energy consumption per unit GNP is also very low

    Energy is vital to society, but our fossil fuel reserves are not inexhaustible and are also a serious source of environmental pollution. Research is required to ensure the long-term supply of energy. Dedicated scientific research can help us to access new sources of energy that will be less harmful to the environment. There is no one plan for energy transition. The research must focus on a system approach to the entire chain, from primary source of energy to end-user. This will involve exploring an extensive portfolio of potential energy options on a world scale. None of the options should be ruled out in advance. Dutch research efforts should be prioritised in association with research being carried out elsewhere. One requirement for ultimately achieving an energy transition that results in a sustainable energy supply is close collaboration between the public and private sectors and centres of expertise. A key factor is that the majority of the parties involved should share the same view of their ultimate goal. The main focus of research should be on energy sources that can make a considerable contribution to a sustainable global energy supply. Another requirement is that these sources must offer the Dutch research community opportunities in both fundamental and applied research. The Foresight Committee advocates the setting up of multidisciplinary research teams. Their long-term task (from idea generation to implementation) will be to analyse and offer guidance to a particular branch of industry or field of energy. Particular attention will go to creating opportunities for excellent young researchers who are pursuing a career in academia. The Foresight Committee has chosen to set up its report according to the various energy options. In Section 2, it notes that there are various ways of approaching energy systems. In addition to energy conservation, another key word is integration. The various options are reviewed in Section 3. The Foresight Committee has

    Full Text Available The uses of fossil fuels cause not only the resources exhaustion but also the environmental problems such as global warming. The purposes of this study are to evaluate paths toward sustainable energy systems and roles of each renewable. In order to realize the purposes, the authors developed the global land use and energy model that figured the global energy supply systems in the future considering the cost minimization. Using the model, the authors conducted a simulation in C30R scenario, which is a kind of strict CO2 emission limit scenarios and reduced CO2 emissions by 30% compared with Kyoto protocol forever scenario, and obtained the following results. In C30R scenario bioenergy will supply 33% of all the primary energy consumption. However, wind and photovoltaic will supply 1.8% and 1.4% of all the primary energy consumption, respectively, because of the limits of power grid stability. The results imply that the strict limits of CO2 emissions are not sufficient to achieve the complete renewable energy systems. In order to use wind and photovoltaic as major energy resources, we need not only to reduce the plant costs but also to develop unconventional renewable technologies.

  4. Case studies to assess and compare different energy sources in sustainable energy and electricity supply strategies. Final report of a co-ordinated project 1997-2000

    International Nuclear Information System (INIS)

    2003-08-01

    The IAEA offers its Member States a comprehensive programme of technical assistance and co-operation, which covers many diverse areas related to peaceful uses of nuclear energy. In the area of comparative assessment, the objective of assistance is to strengthen national capabilities for informed decision making, and for elaborating sustainable choices among alternative options for energy supply and use. In the past, the planning process was designed to meet the future demand for energy at the least engineering cost. However, the pursuit of increasingly sustainable energy options over time has required a broader comparative assessment that addresses economic, social, health and environmental factors. To support this need, in 1992 the IAEA initiated an inter-agency project on databases and methodologies for comparative assessment of different energy sources for electricity generation (DECADES). Under the project, nine international organizations, European Commission (EC), the Economic and Social Commission for Asia and the Pacific (ESCAP), the International Atomic Energy Agency (IAEA), the International Bank for Reconstruction and Development (IBRD), the International Institute for Applied Systems Analysis (IIASA), the Nuclear Energy Agency of the OECD (OECD/NEA), the Organization of the Petroleum Exporting Countries (OPEC), the United Nations Industrial Development Organization (UNIDO) and the World Meteorological Organization (WMO), agreed to pool their efforts to achieve the common objective of enhancing capabilities for comparative assessment of different energy chains in the process of planning and decision making for the electricity sector. DECADES was initially conceived as a set of generic and national databases detailing the environmental impacts, costs and characteristics of various generating and fuel chain technologies which could be used for comparative assessment by investors and policy makers. These databases were linked to software permitting their

    The global dependence on fossil fuels for energy is among the greatest challenges facing our economic, social and political future. The uncertainty in the cost and supply of oil threatens the global economy and energy security, the pollution of fossil combustion threatens human health, and the emission of greenhouse gases threatens global climate. Meeting the demand for double the current global energy use in the next 50 years without damaging our economy, security, environment or climate requires finding alternative sources of energy that are clean, abundant, accessible and sustainable. The transition to greater sustainability involves tapping unused energy flows such as sunlight and wind, producing electricity without carbon emissions from clean coal and high efficiency nuclear power plants, and using energy more efficiently in solid-state lighting, fuel cells and transportation based on plug-in hybrid and electric cars. Achieving these goals requires creating materials of increasing complexity and functionality to control the transformation of energy between light, electrons and chemical bonds. Challenges and opportunities for developing the complex materials and controlling the chemical changes that enable greater sustainability will be presented.

  6. Analysis and Optimization of Power Supply Structure Based on Markov Chain and Error Optimization for Renewable Energy from the Perspective of Sustainability

    2016-07-01

    Full Text Available With the rapid development of renewable energy, power supply structure is changing. However, thermal power is still dominant. With the background in low carbon economy, reasonable adjustment and optimization of the power supply structure is the trend of future development in the power industry. It is also a reliable guarantee of a fast, healthy and stable development of national economy. In this paper, the sustainable development of renewable energy sources is analyzed from the perspective of power supply. Through the research on the development of power supply structure, we find that regional power supply structure development mode conforms to dynamic characteristics and there must exist a Markov chain in the final equilibrium state. Combined with the characteristics of no aftereffect and small samples, this paper applies a Markov model to the power supply structure prediction. The optimization model is established to ensure that the model can fit the historical data as much as possible. Taking actual data of a certain area of Ningxia Province as an example, the models proposed in this paper are applied to the practice and results verify the validity and robustness of the model, which can provide decision basis for enterprise managers.

    A novel multi objective, multi area and multistage model to long-term expansion-planning of integrated generation and transmission corridors incorporating sustainable energy developing is presented in this paper. The proposed MESEDES model is a multi-regional multi-objective and 'bottom-up' energy model which considers the electricity generation/transmission value-chain, i.e., power generation alternatives including renewable, nuclear and traditional thermal generation along with transmission corridors. The model decides the optimal location and timing of the electricity generation/transmission abroad the multistage planning horizon. The MESEDES model considers three objectives belonging to sustainable energy development criteria such as: a) the minimization of investments and operation costs of : power generation, transmission corridors, energy efficiency (demand side management (DSM) programs) considering CO2 capture technologies; b) minimization of Life Cycle Greenhouse Gas Emissions (LC GHG); c) maximization of the diversification of electricity generation mix. The proposed model consider aspects of the carbon abatement policy under the CDM - Clean Development Mechanism or European Union Greenhouse Gas Emission Trading Scheme. A case study is used to illustrate the proposed framework. (author)

    Ireland with its resource of wind has the potential to use this natural resource and sustain the country’s power needs for the future. However, one of the biggest drawbacks to renewable energy generation, particularly wind generated electricity is that it is an intermittent and a variable source of power.

    Full Text Available Collaborative governance plays a critical role in guiding the whole supply chain to achieve its strategic goals. Today’s tremendously changing and competitive business environment imposes a significant challenge for firms to sustain a balance between their self-interest and the required interdependency existed among them within a supply chain. Built upon the extensive literature on the supply chain management, this paper theorizes and proposes a Sustainable Collaborative Governance Framework detailing adaptive decision-making and action mechanisms throughout supply chain lifecycle that will enable the whole supply chain proactively and resiliently respond to uncertainties or perturbations without undergoing significant changes to firms’ normal operations. The framework extends the understanding and practice of the sustainable supply chain management by focusing on its dynamic, elastic, holistic, uncertainty-handling and future-oriented characteristics.

    2004-01-01

    The participants at the Conference called on decision makers both in the European Union (EU) and in Slovakia to provide fair treatment to nuclear power compared with other energy sources, especially with renewable, without prejudice to nuclear safety. This implies ensuring equality in terms of economics, tax, and accounting for externalities. The participants called on the Slovak government to initiate studies that compare the full life-cycle costs, impacts and risks, across the spectrum of energy sources and uses. They should also internalize the external costs. The participants called for a debate on the Slovak energy needs, taking into account the environmental impact of all potential sources of energy and the costs of providing electricity from those sources, and in addition a rational and objective analysis of the security of supply of those sources. It is necessary to have a range of sources for electricity generation that are cost effective and reliable, and respect the environment. The Slovak economy cannot withstand a sudden loss of its guaranteed energy supply. The participants believe that the major government role is setting overall policy for the economy, energy and the environment, with an adequate base in legislation and institutional competence. The Slovak government should have clear strategies for achieving self-sufficient energy-policy goals with reserve power and for meeting climate-change and air-quality goals. The Conference concluded that the nuclear option should remain open in Slovakia, as part of a balanced energy mix, in line with developments abroad and the EU Green Paper from 2000; the alternative is Slovak's failure to secure an affordable energy supply for its citizens. The participants supported the completion of Mochovce 3, 4, complying with enhanced safety requirements, as the most effective option. In Slovenske elektrarne, a.s.

    With an annual turnover of more than 20 billion Swiss Francs energy is an important factor of economic development. Even in periods of seemingly unlimited energy reserves emphasis has to placed on the safety of supply and energy policy has to be adjusted to long term goals. The high impacts of the use of energy are causing external costs of 11 to 16 billion Swiss Francs per year, thereby violating the requirements of a sustainable development. The research programme 'Principles of energy economy' of the Swiss Federal Office of Energy is focused on energy economy and energy policy. In this volume selected projects are presented in a concentrated form to a wider public. Perspectives are drawn up concerning future energy demand, and special attention is paid to the impact of political measures (including various types of taxes) on demand trends and on environmental effects. With the aid of refined models the economic consequences are demonstrated, and significant results are shown which influence the ongoing discussion on double dividends (positive effects on both energy/environment and on economy). The analysis of energy-related measures in the transportation sector including, e.g., promotion measures for renewable energy or consumption-related motor vehicle taxes, is another focus of the programme. In view of a possible revision of the nuclear energy liability act related questions are discussed from the economic point of view. Finally, considerations and results on the role of public service in a liberalized electricity market are reviewed. Dr. R. Meier is head of the research programme 'Principles of energy economy'.

    Due to the global climate change, the power industry has a lot of changes in store. For reasons of environmental protection, the reduction in CO{sub 2} emissions in power generation and loss minimization in power transmission are of particular importance. This means that the share of wind power in a lot of countries, Germany among them, must be as high as possible, for the other ''green'' energy resources, such as hydro or solar power, play only a subordinate part for reasons of their geographical location. Along with sustainability and efficiency of power supply, grid security must be taken into account as well. (orig.)

  20. Estimating Swedish biomass energy supply

    International Nuclear Information System (INIS)

    Johansson, J.; Lundqvist, U.

    1999-01-01

    Biomass is suggested to supply an increasing amount of energy in Sweden. There have been several studies estimating the potential supply of biomass energy, including that of the Swedish Energy Commission in 1995. The Energy Commission based its estimates of biomass supply on five other analyses which presented a wide variation in estimated future supply, in large part due to differing assumptions regarding important factors. In this paper, these studies are assessed, and the estimated potential biomass energy supplies are discusses regarding prices, technical progress and energy policy. The supply of logging residues depends on the demand for wood products and is limited by ecological, technological, and economic restrictions. The supply of stemwood from early thinning for energy and of straw from cereal and oil seed production is mainly dependent upon economic considerations. One major factor for the supply of willow and reed canary grass is the size of arable land projected to be not needed for food and fodder production. Future supply of biomass energy depends on energy prices and technical progress, both of which are driven by energy policy priorities. Biomass energy has to compete with other energy sources as well as with alternative uses of biomass such as forest products and food production. Technical progress may decrease the costs of biomass energy and thus increase the competitiveness. Economic instruments, including carbon taxes and subsidies, and allocation of research and development resources, are driven by energy policy goals and can change the competitiveness of biomass energy

    2018-03-01

    Full Text Available The lands in the northernmost corner of Europe present contradictory aspects in their social and economic development. Urban settlements are relatively few and small-sized, but rich natural resources (minerals, forests, rivers attract energy-intensive industries. Energy demand is increasing as a result of new investments in mining and industries, while reliable energy supply is threatened by the planned phase out of Swedish nuclear power, the growth of intermittent power supplies and the need to reduce fossil fuel consumption, especially in the Finnish and Norwegian energy sectors. Given these challenges, this paper investigates the potentials of so far unexploited energy resources in the northern counties of Finland, Norway and Sweden by comparing and critically analyzing data from statistic databases, governmental reports, official websites, research projects and academic publications. The criteria for the technical and economic definition of potentials are discussed separately for each resource. It is concluded that, despite the factors that reduce the theoretical potentials, significant sustainable techno-economic potentials exist for most of the resources, providing important insights about the possible strategies to contribute to a positive socio-economic development in the considered regions.

    Due to the increasing complexity of the world evolution, the public decision makers, the energy supply industry and the consumers in industrialised countries are more and more sensitive to the vulnerability of energy supply. The emergence of new big consumer countries and the perspective of oil and gas depletion at the end of the current century raise the concerns about how to share fairly the remaining resources for the common and sustainable development of the mankind. Erratic energy prices discourage investment and delay the energy transition. Voluntary measures are needed mainly in industrialised countries in order to develop alternative and sustainable energy sources and to avoid world struggle for energy procurement. In this contribution a synthetic energy vulnerability index is defined for monitoring energy supply vulnerability. The proposed index is based on energy intensity, oil and gas import dependency, CO 2 content of primary energy supply, electricity supply vulnerability and non-diversity in transport fuels. The preliminary assessment of this synthetic index for selected industrialised countries provides promising results that need however further refinement.(author)

The development of renewable energy usage is due to several factors such as the political strategic decisions and geographical situation. Indeed the high development of renewable energies requires challenges from a supply chain point of view. In this paper, a thorough survey of the extant literature on the topic of supply chain (SC) and renewable energy (RE) has been conducted. English papers published on international peer-reviewed journals from 2003 to 2013 have been considered. Sustainable Supply Chain Management (SSCM) resolves the duality between environmental, economic and social aspects. Sustainable manufacturing practices play an essential role in promoting renewable energy development and commercialization; this will require significant changes to the industry’s traditional Supply Chain Management and business model. The aim of the paper is investigate literature insights useful to increase the performance and overcome barriers to the RE supply chain development. Like many typical supply chains, also supply chain related to RE includes elements such as: physical, information, and financial flows. The present research is useful to individualize characteristics of a RE supply chain. Moreover, the research is useful improve the performance of RE supply chain in some aspects like: • better control supply chain costs to make renewable energy more affordable; • manage supply chain to address weakened demand in the near

    The paper presents an overview of sustainable energy development and is aimed to emphasize the important aspects relevant to this activity. A short introduction, related to the present energy outlook with a survey of available data, is presented. This gives the possibility to assess the motivation for a sustainable energy development. Special attention is devoted to the definition of sustainability and its generic meaning. In this respect, particular attention is devoted to the discussion of different aspects of sustainability in the present world. In order to present an engineering approach to the sustainable development, attention is devoted to the review of sustainability criterions as they have to be introduced in the future products. The main emphasis is given to review a potential development in the energy engineering science which may lead to a sustainable energy development. Seven major areas are listed with specific problems and their relevance to the sustainable energy development. This includes the following areas: energy resources and development: efficiency assessment; clean air technologies; information technologies; new and renewable energy resources; environment capacity; mitigation of nuclear power threat to the environment. The education system is the milestone for any economic development. In this respect, sustainable energy development will require special attention to be devoted to the new development of the education system. The distance learning education system is envisages as the potential option for the knowledge dissemination of the new energy technologies. (Author)

  7. Energy sustainability: consumption, efficiency, and ...

    Science.gov (United States)

    One of the critical challenges in achieving sustainability is finding a way to meet the energy consumption needs of a growing population in the face of increasing economic prosperity and finite resources. According to ecological footprint computations, the global resource consumption began exceeding planetary supply in 1977 and by 2030, global energy demand, population, and gross domestic product are projected to greatly increase over 1977 levels. With the aim of finding sustainable energy solutions, we present a simple yet rigorous procedure for assessing and counterbalancing the relationship between energy demand, environmental impact, population, GDP, and energy efficiency. Our analyses indicated that infeasible increases in energy efficiency (over 100 %) would be required by 2030 to return to 1977 environmental impact levels and annual reductions (2 and 3 %) in energy demand resulted in physical, yet impractical requirements; hence, a combination of policy and technology approaches is needed to tackle this critical challenge. This work emphasizes the difficulty in moving toward energy sustainability and helps to frame possible solutions useful for policy and management. Based on projected energy consumption, environmental impact, human population, gross domestic product (GDP), and energy efficiency, for this study, we explore the increase in energy-use efficiency and the decrease in energy use intensity required to achieve sustainable environmental impact le

    Full Text Available Designing the right supply chain that meets the requirements of sustainable development is a significant challenge. Although there are a considerable number of studies on issues relating to sustainable supply chain design (SSCD in terms of designing the practices, processes, and structures, they have rarely demonstrated how these components can be aligned to form an effective sustainable supply chain (SSC. Considering this gap in the literature, this study adopts the configurational approach to develop a conceptual framework that could configure the components of a SSC. In this respect, a process-oriented approach is utilized to classify and harmonize the design components. A natural-resource-based view (NRBV is adopted to determine the central theme to align the design components around. The proposed framework presents three types of SSC, namely, efficient SSC, innovative SSC, and reputed SSC. The study culminates with recommendations concerning the direction for future research.

    More than a dozen energy experts convened in Houston, Texas, on February 13, 2009, for the first in a series of four regionally-based energy summits being held by the Council on Competitiveness. The Southern Energy Summit was hosted by Marathon Oil Corporation, and participants explored the public policy, business and technological challenges to increasing the diversity and sustainability of U.S. energy supplies. There was strong consensus that no single form of energy can satisfy the projected doubling, if not tripling, of demand by the year 2050 while also meeting pressing environmental challenges, including climate change. Innovative technology such as carbon capture and storage, new mitigation techniques and alternative forms of energy must all be brought to bear. However, unlike breakthroughs in information technology, advancing broad-based energy innovation requires an enormous scale that must be factored into any equation that represents an energy solution. Further, the time frame for developing alternative forms of energy is much longer than many believe and is not understood by the general public, whose support for sustainability is critical. Some panelists estimated that it will take more than 50 years to achieve the vision of an energy system that is locally tailored and has tremendous diversity in generation. A long-term commitment to energy sustainability may also require some game-changing strategies that calm volatile energy markets and avoid political cycles. Taking a page from U.S. economic history, one panelist suggested the creation of an independent Federal Energy Reserve Board not unlike the Federal Reserve. The board would be independent and influence national decisions on energy supply, technology, infrastructure and the nation's carbon footprint to better calm the volatile energy market. Public-private efforts are critical. Energy sustainability will require partnerships with the federal government, such as the U.S. Department of Energy

    None of the eight Millennium Development Goals (MDGs) adopted by the United Nations in 2000 directly addressed energy, although for nearly all of them - from eradicating poverty and hunger to improving education and health - progress has depended on greater access to modern energy. Thirteen years later, energy is being given more attention. The target date for the MDGs is 2015, and in 2012 the UN began deliberations to develop sustainable development goals to guide support for sustainable development beyond 2015. The Future We Want, the outcome document of the 2012 United Nations Conference on Sustainable Development (also known as Rio+20) gives energy a central role: ''We recognize the critical role that energy plays in the development process, as access to sustainable modern energy services contributes to poverty eradication, saves lives, improves health and helps provide for basic human needs''

  18. Sustainable desalination using solar energy

    2010-01-01

    Global potable water demand is expected to grow, particularly in areas where freshwater supplies are limited. Production and supply of potable water requires significant amounts of energy, which is currently being derived from nonrenewable fossil fuels. Since energy production from fossil fuels also requires water, current practice of potable water supply powered by fossil fuel derived energy is not a sustainable approach. In this paper, a sustainable phase-change desalination process is presented that is driven solely by solar energy without any reliance on grid power. This process exploits natural gravity and barometric pressure head to maintain near vacuum conditions in an evaporation chamber. Because of the vacuum conditions, evaporation occurs at near ambient temperature, with minimal thermal energy input for phase change. This configuration enables the process to be driven by low-grade heat sources such as solar energy or waste heat streams. Results of theoretical analysis and prototype scale experimental studies conducted to evaluate and demonstrate the feasibility of operating the process using solar energy are presented. Predictions made by the theoretical model correlated well with measured performance data with r 2 > 0.94. Test results showed that, using direct solar energy alone, the system could produce up to 7.5 L/day of freshwater per m 2 of evaporator area. With the addition of a photovoltaic panel area of 6 m 2 , the system could produce up to 12 L/day of freshwater per m 2 of evaporator area, at efficiencies ranging from 65% to 90%. Average specific energy need of this process is 2930 kJ/kg of freshwater, all of which can be derived from solar energy, making it a sustainable and clean process.

    Recent advances in the science and technology of global supply chain management offer near-real-time demand-response systems for decision-makers across production networks. Technology is helping propel "fast fashion" and "lean manufacturing," so that companies are better able to deliver products consumers want most. Yet companies know much less about the environmental and social impacts of their production networks. The failure to measure and manage these impacts can be explained in part by limitations in the science of sustainability measurement, as well as by weaknesses in systems to translate data into information that can be used by decision-makers inside corporations and government agencies. There also remain continued disincentives for firms to measure and pay the full costs of their supply chain impacts. I discuss the current state of monitoring, measuring, and analyzing information related to supply chain sustainability, as well as progress that has been made in translating this information into systems to advance more sustainable practices by corporations and consumers. Better data, decision-support tools, and incentives will be needed to move from simply managing supply chains for costs, compliance, and risk reduction to predicting and preventing unsustainable practices.

No doubt that there is a link between energy consumption and environment capacity reduction. This is an alarming sign, which recently has become the leading theme for our near and distant future. Modern engineering science has to be oriented to those areas which may directly assist in our future energy planning. In this respect, it is demanding need that our attention be oriented to the global aspect og the energy development. Modern technology will help to adopt essential principles of the sustainable energy development. With the appropriate renewable energy resources introduction in our energy future and with the increase of safety of nuclear energy, it will be possible to comply with the main principles to be adapted in the sustainable energy strategy. in order to promote the sustainable energy development the respective education system is required.

    Wind as a source of energy has gained a significant amount of attention because it is free and green. Construction of a wind farm involves considerable investment, which includes the cost of turbines, nacelles, and towers as well as logistical costs such as transportation of oversized parts and installation costs such as crane-rental costs. The terrain effects at the project site exert considerable influence on the turbine assembly rate and the project duration, which increases the overall installation cost. For higher capacity wind turbines (>3MW), the rental cost of the cranes is significant. In this study, the impact of interest rate, sales price of electricity, terrain effects and availability of cranes on the duration of installation and payback period for the project is analyzed. Optimization of the logistic activities involved during the construction phase of a wind farm contributes to the reduction of the project duration and also increases electricity generation during the construction phase.

    Environment concern is one important aspect for supply chain sustainability (SCS). Nowadays, company's activities give a lot of impact on the environment. Through these activities, there are other SCS issue of environment were identified. In this paper, the proposed SCS issue of environmental concern will be determined from Corporate Sustainability Report (CSR). Using a total weightage of 0.333 (after dividing into three aspects of sustainability), each proposed issues will be classified according to the company activities in order to determined weightage for each issue. Those weightages then will be used in developing of score metric for SCS in design phase. Result shows that the carbon footprint is the major concern for SCS of environment while environmental management system is a lowest concern for SCS environment.

    In the brochure under conideration, the Federal Environment Agency (Dessau-Rosslau, Federal Republic of Germany) reports on a sustainable electricity supply in the future. The costs and benefits of the transformation to 100% renewable energy sources are considered. The Federal Environment Agency concludes: A sustainable power supply requires the transition to a fully renewable energy supply. A full supply of electricity from renewable sources by 2050 is feasible technically. Thereby electricity from wind power and solar energy may play a central role in any ambitious expansion scenarios. The cost of power generation from renewable energy already are sunk. This trend will continue. Since the conventional power generation is more expensive in the future, renewable energy pays off more and more. Environmentally harmful subsidies and the lack of consideration of the social costs caused by the fossil and nuclear power generation massively distort the competition at the expense of renewable energy. The transformation of the energy system is worthwhile macroeconomically. The promotion of renewable energies avoids social follow-up costs caused by environmental damages and health related harms. Jobs are created. The regional value added is increased. It also improves the competitiveness of the fast-growing world markets for renewable energy technologies.

    Metin Türkay

    Full Text Available Supply chain management that considers the flow of raw materials, products and information has become a focal issue in modern manufacturing and service systems. Supply chain management requires effective use of assets and information that has far reaching implications beyond satisfaction of customer demand, flow of goods, services or capital. Aggregate planning, a fundamental decision model in supply chain management, refers to the determination of production, inventory, capacity and labor usage levels in the medium term. Traditionally standard mathematical programming formulation is used to devise the aggregate plan so as to minimize the total cost of operations. However, this formulation is purely an economic model that does not include sustainability considerations. In this study, we revise the standard aggregate planning formulation to account for additional environmental and social criteria to incorporate triple bottom line consideration of sustainability. We show how these additional criteria can be appended to traditional cost accounting in order to address sustainability in aggregate planning. We analyze the revised models and interpret the results on a case study from real life that would be insightful for decision makers.

  18. Electricity intensity backstop level to meet sustainable backstop supply technologies

    Verbruggen, Aviel

    2006-01-01

    The concept of a backstop level of electricity intensity is introduced and illustrated for the highest income economies of the world. The backstop level corresponds with the intensity that would be triggered by applying end-use electricity prices equal to the cost price of a fully sustainable electricity supply. Section 1 of the paper discusses the issue of electricity (also energy) intensity of economies. It is argued that identifying a 'demand for electricity intensity' bridges the gap between the high willingness to pay for electricity services on the one hand and the disinterested attitude of consumers regarding the invisible and impalpable product electricity on the other hand. Assessment of the demand curve for electricity intensity in a cross section of high income OECD countries comes to a long-run price elasticity of almost -1. Section 2 revives Nordhaus' concept of backstop supply technologies for weighing three power sources (fossil, nuclear, and renewable sources) in meeting today's criteria of sustainable backstop technology. Only renewable sources meet the main sustainability criteria, but the economic cost of a fully sustainable electricity supply will be elevated. The closing question of Section 3, that is, whether the countries can afford the high cost of backstop electricity supplies, is answered by indicating what reductions in intensity are required to keep the electricity bills stable. The targeted intensity level is called the backstop level, and provides a fixed point for electricity efficiency policies. The analysis supports the call for comprehensive and enduring tax reform policies

    Improvement of the energy balance and efficiency for reduced input of cropping systems is one of the main goals for the cultivation of energy crops. In this field study, two sugar crops for bioethanol production were cultivated under different soil tillage management (conventional; no tillage) and mineral nitrogen application (0, 75, 150 kg N ha −1 ): sweet sorghum and sugar beet. The energy performance and efficiency along the bioethanol supply chain were analysed and compared. Both of these crops showed good growth adaptation to the different soil and nitrogen management, and thus the energy return, resource and energy efficiencies were significantly improved in the low-input system. Sweet sorghum provided better responses in terms of water and nitrogen use efficiency for biomass accumulation, as well as its energy yield and net gain, compared to sugar beet, whereas sugar beet showed higher energy efficiency than sorghum. According to these data, both of these crops can be cultivated in a Mediterranean environment with low energy input, which guarantees good crop and energy performances for biofuel strategy planning. - Highlights: • Two sugar crops for the bioethanol supply chain were evaluated. • Energy performances and efficiencies were assessed under different energy input. • Sugar yield resulted not compromised by the different crop management. • The energy gain was improved with low energy input at field level. • Sweet sorghum gave the highest energy yield, sugar beet the energy efficiency.

    1988-01-01

    The book is devoted to the problem of energy planning for a sustainable world. The principal objective of the conventional approach to energy problem is economic growth and consequently the primary goal of conventional energy planning is to make energy supply expansion possible. This conventional approach is aggravating societal inequalities, environmental and security problems, and eroding self-reliance. On the other hand societal goals in energy planning should be equity, economic efficiency, environmental harmony, long-term viability, self-reliance and peace. These goals are relevant to both developing and industrialised countries. These goals should, therefore, be incorporated in a normative approach to energy planning. This can be done by focussing on end-uses of energy and the services which energy performs. In the first chapter, the relation of global energy problem with other major global problems such as North-South disparities, environmental degradation, climate change, population explosion and nuclear weapons is brought out. The energy strategies for industrialized countries and for developing countries are examined in chapters 2 and 3 respectively. The focus in both chapters is on end-uses of enegy, management of energy demand and exploitation of synergisms. In chapter 4, rough estimates of global energy demand are given and an illustrative energy scenario compatible with societal goals is described. In chapter 5, the policies necessary to implement end-use-oriented energy strategies are outlined. These policies relate to market mechanisms, administrative allocation of energy carriers, regulation and taxes. In the concluding chapter 6, the political feasibility of implementing the kind of energy future envisaged is discussed. The main finding of the authors is that it is possible to formulate energy strategies compatible with the solution of major global problems referred to in chapter 1 with about the same level of global energy use as today.

    Considerations about 'post-Kyoto' targets and other ways to achieve the objectives of the Protocol are critical. Scientific evidence presented by the IPCC in its third assessment in 2002 clearly indicates the need not only to implement the Protocol, but also to agree on further emission reductions in the medium term in order to keep changes in the world's climate at a manageable level. UNEP's Energy Programme addresses the environmental consequences of energy production and use, such as global climate change and local air pollution. UNEP assists decision makers in government and the private sector to make better, more informed energy choices, which fully integrate environmental and social costs. Since UNEP is not an implementing organization, its role as facilitator is core. The majority of UNEP's energy activities link to mitigation - the reduction of greenhouse gas emissions - but these are generally accompanied by broader objectives related to energy and sustainable development. This includes climate change mitigation, but not as the sole objective since many of UNEP's partners in developing countries have more immediate development objectives. UNEP's main programmes are: The Solar and Wind Energy Resource Assessment (SWERA) project, that provides solar and wind resource data and geographic information assessment tools to public and private sector executives who are involved in energy market development; A new Global Environment Facility (GEF) funded programme aiming at promoting industrial energy efficiency through a cleaner production/environmental management system framework. A parallel programme, Energy Management and Performance Related Energy Savings Scheme (EMPRESS), supports energy efficiency efforts in Eastern and Central Europe; The Mediterranean Renewable Energy Programme promotes the financing of renewable energy projects in the Mediterranean basin; The Rural Energy Enterprise Development (REED) seeks to develop new

    The Hopi Tribal Government as part of an initiative to ?Regulate the delivery of energy and energy services to the Hopi Reservation and to create a strategic business plan for tribal provision of appropriate utility, both in a manner that improves the reliability and cost efficiency of such services,? established the Hopi Clean Air Partnership Project (HCAPP) to support the Tribe?s economic development goals, which is sensitive to the needs and ways of the Hopi people. The Department of Energy (DOE) funded, Formation of Hopi Sustainable Energy Program results are included in the Clean Air Partnership Report. One of the Hopi Tribe?s primary strategies to improving the reliability and cost efficiency of energy services on the Reservation and to creating alternative (to coal) economic development opportunities is to form and begin implementation of the Hopi Sustainable Energy Program. The Hopi Tribe through the implementation of this grant identified various economic opportunities available from renewable energy resources. However, in order to take advantage of those opportunities, capacity building of tribal staff is essential in order for the Tribe to develop and manage its renewable energy resources. As Arizona public utilities such as APS?s renewable energy portfolio increases the demand for renewable power will increase. The Hopi Tribe would be in a good position to provide a percentage of the power through wind energy. It is equally important that the Hopi Tribe begin a dialogue with APS and NTUA to purchase the 69Kv transmission on Hopi and begin looking into financing options to purchase the line.

  14. Green energy strategies for sustainable development

    International Nuclear Information System (INIS)

    Midilli, Adnan; Dincer, Ibrahim; Ay, Murat

    2006-01-01

    In this study we propose some green energy strategies for sustainable development. In this regard, seven green energy strategies are taken into consideration to determine the sectoral, technological, and application impact ratios. Based on these ratios, we derive a new parameter as the green energy impact ratio. In addition, the green energy-based sustainability ratio is obtained by depending upon the green energy impact ratio, and the green energy utilization ratio that is calculated using actual energy data taken from literature. In order to verify these parameters, three cases are considered. Consequently, it can be considered that the sectoral impact ratio is more important and should be kept constant as much as possible in a green energy policy implementation. Moreover, the green energy-based sustainability ratio increases with an increase of technological, sectoral, and application impact ratios. This means that all negative effects on the industrial, technological, sectoral and social developments partially and/or completely decrease throughout the transition and utilization to and of green energy and technologies when possible sustainable energy strategies are preferred and applied. Thus, the sustainable energy strategies can make an important contribution to the economies of the countries where green energy (e.g., wind, solar, tidal, biomass) is abundantly produced. Therefore, the investment in green energy supply and progress should be encouraged by governments and other authorities for a green energy replacement of fossil fuels for more environmentally benign and sustainable future

    All energy systems have adverse as well as beneficial impacts on the environment. They vary in quality, quantity, in time and in space. Environmentally sensitive energy management tries to minimize the adverse impacts in an equitable manner between different groups in the most cost-effective ways. Many of the enviornmental impacts of energy continue to be externalized. Consequently, these energy systems which can externalize their impacts more easily are favoured, while others remain relatively expensive. The lack of full integration of environmental factors into energy policy and planning is the overriding problem to be resolved before a transition towards sustainable energy futures can take place. The most pressing problem in the developing countries relates to the unsustainable and inefficient use of biomass resources, while in the industrialized countries, the major energy-environment problems arise out of the continued intensive use of fossil fuel resources. Both of these resource issues have their role to play in climate change. Although there has been considerable improvement in pollution control in a number of situations, most of the adverse impacts will undoubtedly increase in the future. Population growth will lead to increased demand, and there will also be greater use of lower grade fuels. Climate change and the crisis in the biomass resource base in the developing countries are the most critical energy-environment issues to be resolved in the immediate future. In both cases, international cooperation is an essential requirement for successful resolution. 26 refs.

  18. Sustainable supply chain management: current debate and future directions

    Directory of Open Access Journals (Sweden)

    Bruno Silvestre

    Full Text Available Abstract This paper is a research brief on sustainable supply chain management and covers some of the key elements of literature’s past debate and trends for future directions. It highlights the growth of this research area and reinforces the importance of a full consideration of all three key dimensions of sustainability when managing sustainable supply chains, i.e., the financial, environmental and social dimensions. Therefore, supply chain decision makers need to unequivocally assess the impact of their decisions on the financial, environmental and social performances of their supply chains. This paper also argues that risks and opportunities are the key drivers for supply chain decision makers to adopt sustainability within their operations, and that barriers to sustainability adoption exist. This research highlights that, depending on the focus adopted, supply chains can evolve and shift from more traditional to more sustainable approaches over time. The paper concludes with some promising avenues for future investigation.

  2. Decentralized energy supply on the liberalized market

    Pauli, H.

    1999-01-01

    Starting in 2001, the electricity market is to be progressively liberalized. The process will be completed by the year 2006. What role will decentralized power generation using combined cycle power plants play on a liberalized market ? The background conditions are essentially favourable: both the new energy act, which has been in force since 1 January 1999, and the planned energy levy suggest that this technology will become increasingly widespread. In addition, the price trend for combined cycle plants components together with low energy costs are having a favourable impact. On the other hand, great uncertainty is being created by the process of liberalization and the current flood of investments in power generation. However, electricity supply is unlikely to be in surplus for long in a context of sustained economic growth. (author)

  3. Sustainable and Resilient Supply Chain Network Design under Disruption Risks

    2014-09-01

    Full Text Available Sustainable supply chain network design is a rich area for academic research that is still in its infancy and has potential to affect supply chain performance. Increasing regulations for carbon and waste management are forcing firms to consider their supply chains from ecological and social objectives, but in reality, however, facilities and the links connecting them are disrupted from time to time, due to poor weather, natural or manmade disasters or a combination of any other factors. Supply chain systems drop their sustainability objectives while coping with these unexpected disruptions. Hence, the new challenges for supply chain managers are to design an efficient and effective supply chain network that will be resilient enough to bounce back from any disruption and that also should have sufficient vigilance to offer same sustainability under a disruption state. This paper focuses on ecological sustainability, because an environmental focus in a supply chain system is more important and also links with other pillars of sustainability, as the products need to be produced, packed and transported in an ethical way, which should not harm social balance and the environment. Owing to importance of the considered issue, this paper attempts to introduce a network optimization model for a sustainable and resilient supply chain network by incorporating (1 sustainability via carbon emissions and embodied carbon footprints and (2 resilience by incorporating location-specific risks. The proposed goal programming (GP model optimizes the total cost, while considering the resilience and sustainability of the supply chain network.

  4. Energy supply and energy policy in Switzerland

    International Nuclear Information System (INIS)

    Kiener, E.

    1985-01-01

    The article gives an outline of the problems of energy supply in Switzerland, with some emphasis upon the extent to which Federal and Cantonal constitutions and the functioning of Swiss democracy, notably the relatively frequent recourse to referendums and the strong public interest in conservation and ecology, affect the nature of decisions upon technical matters such as the authorisation and siting of generating plants and the construction of transmission lines. The dominating factor in the energy situation in Switzerland has been and will remain the need to import about 84% of the energy used, mainly in the form of oil, the cost of which is nearly 10% of the total value of all imports. Water power accounts for 13% of the total supply and is approaching the limit of its possible development. The use of energy constantly increases but the political difficulties in the way of providing the consequently necessary resources increase if anything still more rapidly. The resulting difficult situation is discussed in some detail. The author urges the energy industry to view its political difficulties in a positive manner, and to see them rather as a spur to effort than as merely an unwelcome obstacle to private enterprise.

    The idea behind the Universal Energy Supply Protocol (UESP) is to equip all components (all kinds of generators, batteries and loads) with an identical and well-defined electrical DC connection as well as with intelligence and a communication interface, speaking a defined protocol (UESP). Power flow and information flow are separated, leading to more flexibility in system sizing and standardisation. A centralised control and energy management system administers the system as a whole. Its software is able to manage the energy generation and consumption and ensures the required level of reliability while reducing the operational cost to a minimum. In contrast to existing management concepts, the central idea behind UESP is to outsource the intelligence and the knowledge on the operational behaviour of the components out of the central management system into the components themselves. The components provide information about their current status of operation, current and future operation cost and constraints to the central management system. Here, using 'virtual stock exchange' algorithms, an optimised schedule for all components is determined and fed back to the components for implementation. The central management is thus very generic and can handle any component using the UESP protocol. It automatically adapts to new or changed system configurations, as these changes impact the optimisation only by additional 'players' on the virtual stock market. Eight German companies have teamed up with Fraunhofer ISE in a challenging project (funded by the German Ministry for the Environment, Nature Conservation and Nuclear Safety, BMU) to define the previously described protocol and interfaces and to elaborate the various implementations. The applications range form village power supply systems to telecommunication stations and signalling systems. It is foreseen to establish UESP as standardised interface in the future. (orig.)

    Full Text Available This paper explores the cumulative sustainable supply chain (SC capabilities and their effects on supply chain performance, including economic, environmental, and social performance. Using empirical analyses with data from 198 small- and medium-sized suppliers in Korea, this paper provides evidence about the cumulative sustainable SC capabilities, indicating that economic, social, and environmental capabilities in the supply chain mutually reinforce each other rather than traded off. This study also presents the positive effect of cumulative sustainable SC capabilities on supply chain sustainability performance. This paper identifies four distinctive groups of cumulative capabilities: the laggard, environmental-focused, social-cautious, and all-round. This study provides a better understanding about sustainable capabilities and important guidelines for managers of suppliers and buyers who wish to build strong social/environmental management capabilities without compromising economic capability throughout the entire supply chain.

    2015-06-01

    Full Text Available From sustainability perspective, the supply chain management strategy can use different indicators related to Triple Bottom Line to improve its practices. Some studies in the topic have focused only environmental issues; however in some cases the social issues should be considered as a core of the sustainable strategies. Considering this view, the paper aims to highlight the relevance of social issues in the Brazilian context toward sustainable supply chain. Therefore, a theoretical essay was conducted using the literature about sustainable supply chain in relation to the Brazilian perspective to understand how it is possible to use new approaches for a more emphasis on social issues. The discussions indicates that to re-conceptualize the social relations in supply chains, it's necessary to use corporate social responsibility and social capital approaches to create a better discussion about sustainable supply chain. The proposal starts a discussion in the Brazilian context to stimulate new scholars to study this topic.

    This paper outlines the approach to the evaluation of sustainability of current and future electricity supply options of interest for a major Swiss utility Axpo Holding AG. The motivation behind this effort has been to provide a solid basis for a state-of-the-art interdisciplinary assessment and use this framework within a dialog with a wide spectrum of stakeholders. The development and implementation of the methodology was coordinated by Axpo in co-operation with the Paul Scherrer Institut (PSI) and other scientific institutions. The evaluation covers environmental, social and economic dimensions of sustainability. Methods used include among others Life Cycle Assessment (LCA), Impact Pathway Approach (IPA) and Probabilistic Safety Assessment (PSA). The associated databases developed by PSI have been extensively used, subject to major extensions necessary for analysing the future technologies. Learning curves were employed for future cost estimates. Furthermore, particularly in the social area expert surveys were used. The results were aggregated using total (internal plus external) costs approach and Multi-criteria Decision Analysis (MCDA). For MCDA a set of criteria and the associated indicators was established. In total 75 indicators were quantified, including 11 environmental, 33 social and 31 economic. 18 current and 18 future technologies have been analysed including nuclear as well as fossil and renewable technologies. Total costs were estimated for these technologies providing a clear ranking with nuclear having the lowest costs and some of the renewable showing remarkable cost reductions until 2030. This ranking is partially controversial mainly due to the limited representation of social aspects in the total costs.

    This paper outlines the approach to the evaluation of sustainability of current and future electricity supply options of interest for a major Swiss utility Axpo Holding AG. The motivation behind this effort has been to provide a solid basis for a state-of-the-art interdisciplinary assessment and use this framework within a dialog with a wide spectrum of stakeholders. The development and implementation of the methodology was coordinated by Axpo in co-operation with the Paul Scherrer Institut (PSI) and other scientific institutions. The evaluation covers environmental, social and economic dimensions of sustainability. Methods used include among others life cycle assessment (LCA), impact pathway approach (IPA) and probabilistic safety assessment (PSA). The associated databases developed by PSI have been extensively used, subject to major extensions necessary for analyzing the future technologies. Learning curves were employed for future cost estimates. Furthermore, particularly in the social area expert surveys were used. The results were aggregated using total (internal plus external) costs approach and multi-criteria decision analysis (MCDA). For MCDA a set of criteria and the associated indicators was established. In total 75 indicators were quantified, including 11 environmental, 33 social and 31 economic. Eighteen current and 18 future technologies have been analysed including nuclear as well as fossil and renewable technologies. Total costs were estimated for these technologies providing a clear ranking with nuclear having the lowest costs and some of the renewables showing remarkable cost reductions until 2030. This ranking is partially controversial mainly due to the limited representation of social aspects in the total costs. The results of MCDA-applications involving elicitation of preferences from a relatively homogeneous stakeholder group, i.e. 85 employees of the Axpo Group (including also NOK, EGL, CKW and Axpo IT), are summarized.

  18. Energy and sustainable development in Finland

    International Nuclear Information System (INIS)

    2003-01-01

    The U.N. World Summit on Environment and Development in Rio de Janeiro in June 1992 was the origin of the international framework for sustainable development. As a basis for joint, sustainable action by governments, organizations, industries, and the public, the participating countries signed the Rio Declaration on Environment and Development, and drafted the associated action program, Agenda 21. Sustainable development comprises these three determinant factors: - Economy. - Ecology. - Social aspects. This is where entrepreneurial responsibility for society comes in. If industries want to generate overall positive effects, they must be efficient, competitive, and profitable on a long-term basis. Power supply systems meeting the criteria of sustainable development must be reliable, economically viable, socially acceptable, and environmentally compatible. The power supply in Finland is meeting these sustainability requirements in many ways. Finland's electricity supply is decentralized, using a variety of energy sources. Electricity can be generated and made available at low cost. The Finnish power industry is an important employer and a major factor in the economy. Moreover, electricity is generated in advanced types of power plants. In this way, the structure of the Finnish power supply system incorporates important factors of sustainable development. (orig.)

    2014-09-01

    Full Text Available Sustainability is significantly important for fashion business due to consumers’ increasing awareness of environment. When a fashion company aims to promote sustainability, the main linkage is to develop a sustainable supply chain. This paper contributes to current knowledge of sustainable supply chain in the textile and clothing industry. We first depict the structure of sustainable fashion supply chain including eco-material preparation, sustainable manufacturing, green distribution, green retailing, and ethical consumers based on the extant literature. We study the case of the Swedish fast fashion company, H&M, which has constructed its sustainable supply chain in developing eco-materials, providing safety training, monitoring sustainable manufacturing, reducing carbon emission in distribution, and promoting eco-fashion. Moreover, based on the secondary data and analysis, we learn the lessons of H&M’s sustainable fashion supply chain from the country perspective: (1 the H&M’s sourcing managers may be more likely to select suppliers in the countries with lower degrees of human wellbeing; (2 the H&M’s supply chain manager may set a higher level of inventory in a country with a higher human wellbeing; and (3 the H&M CEO may consider the degrees of human wellbeing and economic wellbeing, instead of environmental wellbeing when launching the online shopping channel in a specific country.

  1. Nanotechnology for sustainable energy

    2011-01-01

    Nanotechnology and its applications have captured a worldwide market. Nanomaterials that have been developed using this technology can be incorporated into the devices so that renewable energy can be converted or generated more efficiently. Nanomaterials have the potential to change the way we generate, deliver and use energy. Hydrogen cells are used in auto industry as a viable power source. Compressed hydrogen tanks are used to supply Hydrogen, and Oxygen is used from the air directly. There is no pollution caused by hydrogen fuel cell autos since the only emission is water. Organic dyes (dye sensitizers), which are sensitive to light, can absorb a broader range of the sun's spectrum. A dye-sensitized solar cell has three primary parts. On top is a transparent anode made of fluoride-doped tin dioxide (SnO/sub 2/: F) deposited on the back typically of a glass plate. On the back of this conductive plate is a thin layer of titanium dioxide (TiO/sub 2/), which forms into a highly nanoporous structure with an extremely large surface-area. After soaking the film in the dye solution, a thin layer of the dye is left covalently bonded to the surface of the TiO/sub 2/ . Computational material science and nanoscience can play many critical roles in renewable energy research. These include: finding the right materials for hydrogen storage; finding the most reliable and efficient catalyst for water dissociation in hydrogen production; finding a cheap, environmentally benign, and stable material for efficient solar cell applications; and understanding the photo-electron process in a nanosystem, and hence helping design efficient nanostructure solar cells.

    Full Text Available Now a day, sustainable supply chain is the crucially considerable matter for future focused industries. As a result, attention in supply chain management has increasingly amplified since the 1980s when firms discovered its benefits of mutual relationships within and beyond their own organization. This is why, concern researchers are trying hard to develop new theory or model which might help the corporate sector for achieving sustainability in their supply chains. This kind of reflection can be seen by the number of papers published and in particular by journal since 1980. The objectives of this paper are twofold. First, it offers a literature review on sustainable supply chain management taking papers published in last three decades. Second, it offers a conceptual sustainable supply chain process model in light of triple bottom line theory. The model has been developed by taking in-depth interview of an entrepreneur from a Poultry case industry in Bangladesh.

  5. Sustainable Water Supplies in Uppsala, Sweden?

    Science.gov (United States)

    Eriksson, Bert

    2014-05-01

    This is a description of a transdisciplinary three-day project with upper secondary school students around ecosystem services and sustainability. Uppsala (200 000 inhabitants) gets its municipal water from wells in the esker that dominates the landscape in and around the town. This esker was formed by glacial melt water around 11 000 BP, at the end of the latest glaciation and was lifted above sea level by post-glacial land rise from 6000 BP. To keep up the water table in the esker, water from river Fyris is pumped up and infiltrated in the esker. The river is also the recipient of wastewater downstream of the town, and the river runs out into Lake Mälaren that in its turn spills out into the Baltic Sea through Stockholm. The esker and river can thus be a central topic to work around, in Biology and Geography in upper secondary school, concerning recent and future water supplies, quaternary geology, limnology and landscape history. The fieldwork is carried out during three days in a period of three subsequent weeks. 1. One day is used to examine the water quality in the river above the town, organisms, pH, levels of nitrogen and phosphorous, conductivity and turbidity. Then the direction of the water is followed, first up to the infiltration dams on the esker, and then along the esker to the wells in the town. The formation of the esker and other traces in the landscape from the latest glaciation is also studied, as well as the historical use of the esker as a road and as a source of gravel and sand. The tap water that comes from the wells is finally tested in school in the same way as in the river. 2. The second day is used to follow the wastewater from households to the sewage plant, where the staff presents the plant. The water quality is tested in the same way as above in the outlet from the plant to the river. 3. The third day consists of a limnological excursion on the lake outside the mouth of the river where plankton and other organisms are studied, as

    There is widespread interest in the way that smart energy control systems, such as assessment and monitoring techniques for low carbon, nearly-zero energy and net positive buildings can contribute to a Sustainable future, for current and future generations. There is a turning point on the horizon for the supply of energy from finite resources such as natural gas and oil become less reliable in economic terms and extraction become more challenging, and more unacceptable socially, such as adverse public reaction to ‘fracking’. Thus, in 2016 these challenges are having a major influence on the design, optimisation, performance measurements, operation and preservation of: buildings, neighbourhoods, cities, regions, countries and continents. The source and nature of energy, the security of supply and the equity of distribution, the environmental impact of its supply and utilization, are all crucial matters to be addressed by suppliers, consumers, governments, industry, academia, and financial institutions.

    Schweizer-Ries, Petra

    2008-01-01

    Energy sustainability is becoming an increasing issue-or rather 'the' issue in our society. Often it is reduced to a purely technical problem. Renewable energies and energy-efficient technologies are developed to solve the problem, but finally the end-users will 'decide' how much and what kind of energy they are going to consume. This article is targeted on showing the environmental psychological aspects of the change of energy demand and supply. It builds upon a transactional model of human technology interchange and summarises environmental psychological work done during more than 5 years. It refers to the idea of energy sustainable communities (ESCs), shows the development of one example community and concentrates on one aspect of the social dimension of ESCs, the 'acceptance of renewable energy technology', its definition and measurement in Germany

  9. Supply Chain Management and Sustainability: Procrastinating Integration in Mainstream Research

    Directory of Open Access Journals (Sweden)

    Marisa P. de Brito

    2010-03-01

    Full Text Available Research has pointed out opportunities and research agendas to integrate sustainability issues with supply chain and operations management. However, we find that it is still not mainstream practice to systematically take a sustainability approach in tackling supply chain and operations management issues. In this paper, we make use of behavioral theory to explain the current lack of integration. We conclude through abductive reasoning that the reasons for procrastinating integration of sustainability in supply chain and operations management research are the conflicting nature of the task and the inherent context, which is the focus on operations rather than environmental or social issues.

  10. Valuing diversity in energy supply

    International Nuclear Information System (INIS)

    Skea, Jim

    2010-01-01

    There is renewed interest in the role of supply diversity in promoting energy security. This paper explores ways of valuing diversity. A possible incentive mechanism for promoting diversity which takes account of underlying 'disparities' between different technology options is developed. The mechanism provides a way of trading off cost and diversity and results in an 'efficient' cost-diversity frontier by analogy with financial portfolio theory. If all technologies are believed to be equally disparate, the appropriate mechanism is a 'levy' imposed on market share. If the technologies are not equally disparate, the levy needs to be adjusted by technology-specific multipliers that take account of levels of disparity and patterns of market share. The analysis is applied to two stylised situations. In the long-run equilibrium case, the implications of both different patterns of disparity and different values attached to diversity are investigated. The paper also explores the implications of applying such a mechanism to the current Great Britain electricity system. The implications in terms of financial flows, for both the market as a whole and for individual operators, are investigated. Finally, the appropriateness of such a mechanism in the light of other policy goals, and possible future research directions, is discussed. (author)

    Highlights: • A MINLP model for designing sustainable biodiesel supply network is developed. • Emergy sustainability index is used as the objective to be maximized. • Multiple alternatives in each stage of biodiesel supply network are considered. • Life cycle perspective is incorporated in the design of biodiesel supply network. - Abstract: Sustainability is an important and difficult consideration for the stakeholders/decision-makers when planning a biofuel supply network. In this paper, a Mixed-Integer Non-linear Programming (MINLP) model was developed with the aim to help the stakeholders/decision-maker to select the most sustainable design. In the proposed model, the emergy sustainability index of the whole biodiesel supply networks in a life cycle perspective is employed as the measure of the sustainability, and multiple feedstocks, multiple transport modes, multiple regions for biodiesel production and multiple distribution centers can be considered. After describing the process and mathematic framework of the model, an illustrative case was studied and demonstrated that the proposed methodology is feasible for finding the most sustainable design and planning of biodiesel supply chains

    The electric utility sector is of central importance for economic growth and social development. While numerous societal and economic benefits arise from electricity production, it can also have impacts which may not be fully and unanimously reconciled with the concept of sustainability. Moving the electricity sector towards sustainable development calls for the integration of environmental, social and economic aspects in the decision-making process. As an input to such a process, one needs to assess how the different options perform with respect to specific sustainability criteria. As a part of the ''Comprehensive Assessment of Energy Systems'', carried out by the Paul Scherrer Institute (PSI), the electricity and heat supply systems are examined in view of sustainability criteria and the associated indicators, thus allowing operationalization of the sustainability concept

As a benchmark, we first obtain the equlibrium price and product sustainability level in a vertically integrated supply chain. Our analysis provides some interesting findings in a decentralized supply chain: (i a dominant manufacturer (retailer always benefits from its power; (ii the entire supply chain earns the most profit from the Nash game, and the least from the retailer Stackelberg game, respectively; (iii as the power shifts from the manufacturer to the retailer, product sustainability and retail price increase; (iv dominant manufacturer does not necessarily imply low wholesale price that would benefit the retailer. Managerial insights are provided for the manufacturer and the retailer, respectively.

    Almost 40 years after the Agency’s founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate. Yet over the course of its history, the IEA’s responsibilities have expanded along with both the international energy economy and conceptions of energy security itself. Our mission to promote secure and sustainable energy provision spans the energy mix. At the same time, a changing global energy map means that the industrialised nations of the world no longer dominate energy consumption. The IEA must work in close co-operation with partner countries and organisations worldwide to achieve its three core objectives: energy security, economic prosperity, and environmental sustainability. Working toward international commitments to reduce greenhouse gas emissions that cause global climate change; facilitating energy technology exchange, innovation and deployment; improving modern energy access to the billions of people who are without it; bolstering both cleanliness and security through energy efficiency; and promoting flexible and functioning energy markets – these efforts complement our traditional core responsibilities of mitigating the effects of supply disruptions and improving statistical transparency.

    Globally, buildings are responsible for approximately 40% of the total world annual energy consumption. Most of this energy is for the provision of lighting, heating, cooling, and air conditioning. Increasing awareness of the environmental impact of CO 2 and NO x emissions and CFCs triggered a renewed interest in environmentally friendly cooling, and heating technologies. Under the 1997 Montreal Protocol, governments agreed to phase out chemicals used as refrigerants that have the potential to destroy stratospheric ozone. It was therefore considered desirable to reduce energy consumption and decrease the rate of depletion of world energy reserves and pollution of the environment. One way of reducing building energy consumption is to design building, which are more economical in their use of energy for heating, lighting, cooling, ventilation and hot water supply. Passive measures, particularly natural or hybrid ventilation rather than air-conditioning, can dramatically reduce primary energy consumption. However, exploitation of renewable energy in buildings and agricultural greenhouses can, also, significantly contribute towards reducing dependency on fossil fuels. Therefore, promoting innovative renewable applications and reinforcing the renewable energy market will contribute to preservation of the ecosystem by reducing emissions at local and global levels. This will also contribute to the amelioration of environmental conditions by replacing conventional fuels with renewable energies that produce no air pollution or greenhouse gases. The provision of good indoor environmental quality while achieving energy and cost-efficient operation of the heating, ventilating and air-conditioning (HVAC) plants in buildings represents a multi-variant problem. The comfort of building occupants is dependent on many environmental parameters including air speed, temperature, relative humidity and quality in addition to lighting and noise. The overall objective is to provide a high

    In general, increasing a country's energy supply security does not come for free. It costs money to build up a strategic reserve, to increase supply diversity or even to accelerate energy efficiency improvements. Nor are all investments in increasing energy supply security cost effective, even if the shocks they are designed to insure against can be predicted with 100% accuracy. The first half of the paper surveys different definitions and strategies associated with the concept of energy supply security, and compares current initiatives to establish an 'assured supply of nuclear fuel' to the International Energy Agency's (IEA's) system of strategic national oil reserves. The second half of the paper presents results from several case studies of the costs and effectiveness of selected energy supply security policies. One case study examines alternative strategies for Lithuania following the scheduled closure of the Ignalina-2 nuclear reactor in 2009. The second case study examines, for countries with different energy resources and demand structures, the effectiveness of a policy to increase supply diversity by expanding renewable energy supplies.

    Full Text Available With the emergence of environmental protection as a global issue, implementing environmental practices for sustaining green supply chain management (GSCM has received a lot of attention. This study investigates the impact of integration with suppliers and supply disruption risk on environmental practices. It also examines the role of supplier integration and supply disruption risk on performance. Finally, it investigates the relationship between environmental practices and performance in order to sustain green supply chains. Based on 272 survey responses from supply and purchase managers, our research results support the positive impact of integration with suppliers and the negative impact of supply disruption risk on the adoption of environmental practices. Furthermore, they provide empirical evidence that environmental practices and integration with suppliers are positively associated with performance, while supply disruption risk is negatively associated with performance. This study identifies antecedents and establishes a research framework of GSCM. More importantly, it provides meaningful insights to managers regarding the implementation of environmental practices related to other supply chain practices for sustaining green supply chains.

    Full Text Available One of Indonesia’s problem as an archipelagic country is unequally electrification ratio, especially in Indonesia eastern region. In 2015, the electrification ratio in Kupang is 58.67%. This figure is far below from Indonesia electrification ratio, which is 88.3%. At present, people of Kupang get their electricity supply from fuel energy power system, which is costly and has a bad impact for environment. Furthermore, Indonesia has many renewable resource that has not been fully utilized and this condition in line with acceleration program of electricity infrastructure development in Indonesia, considering that Kupang has a geothermal potential in Mataloko. This research aims to develop a dynamical model of Mataloko geothermal power plant 1 x 2.5 mw development strategy in Kupang, East Nusa Tenggara from technical and economical aspect. We used system dynamics to modelling the existing electricity condition in Kupang as a base model to develop scenarios. We hope this scenario can be taken as consideration to develop a renewable resource power plant in order to fulfill the electricity demand. The result shows that geothermal potential in Mataloko is feasible to generate an electricity

    The escalation of oil prices and the issue of energy supply security have emphasized the importance of a more rapid implementation of sustainable energy sector elements - renewable energy sources and energy efficiency. Croatia has recorded an increasingly negative balance of payments due to a considerable discrepancy between its import and its export, the former involving a significant amount of fossil fuels. Croatia has relatively scarce fossil fuels resources; on the other hand, its renewable energy sources as well as the possibility of energy efficiency improvement are comparatively abundant. Consequently, an increased use of renewable energies and the improvement of its energy efficiency are in the best interest of the Republic of Croatia.(author)

    2016-12-01

    Full Text Available Background: The issue of managing sustainability in supply chain seems to be more and more complex. There are many aspects that need to be taken into consideration when planning, implementing and monitoring environmental and social conditions of supply chains. Despite many works, already published, on the concept of sustainable development (SD is seems that the issue of assessment and especially the issue of maturity in the light of the SD concept is still not developed enough. Methods: The general aim of the paper is the analysis of the maturity issue in the context of sustainability. The main objective is to conceptualize the idea of maturity in sustainable supply chain. Beside the literature research the own proposition of theoretical model was described. Results: The article describes the issue of maturity as an element of managing sustainable development in the supply chain. The author presented a theoretical model of the maturity. Moreover the author gave some recommendations how to manage the sustainability issues in supply chain in more mature approach and introduced some useful tools among which are: certification, code of conduct and code of ethics, audits, projects etc. Conclusions: The issue of maturity seems to be very useful for proper understanding the idea of sustainable development in supply chain. The developed model can be used as self-assessment method to check at which level of implementation the idea of SD is analyzed in supply chain. Furthermore, the next phase of the planned research in form of practical verification of the model was advised as well as a research of identification of new factors and tools in analyzed area.

    This paper addresses sustain ability criteria and the associated indicators allowing ope rationalization of the sustain ability concept in general and specially in the context of electricity supply. The criteria and indicators cover economic, environmental and social aspects. Egypt has rapidly growing population and per capita demand. As a signatory of the framework convention on climate change, Egypt is making all efforts to comply with the strategy of Egypt to meet the challenge of the increasing demand management, integrating it into national decision making and improving environmental performance continuously: for the electricity sector, this can be summarized in improvement of power system efficiency by all available means. On the other hand energy conservation and demand side management programs are ongoing, also the environmental consideration has become one of the major issues in calculating the feasibility of any new addition to the system. This paper deals with the review of the Macro Indicators based on total greenhouse emissions provide a measure of overall performance. Then propose the Primary Indicators. A set of performance indicators is developed against which implementation of the national strategy measures aimed at reducing green house gas emissions can be evaluated. Some selected results from environmental analysis are given. In the study about 20 indicators are used as a measure of the overall performance relative to targets and benchmarks for past and future projections up to year 2020. The potential performance indicators for energy sector include: fossil fuel consumption (primary energy), greenhouse gas emissions from energy sector, energy related greenhouse gas emissions per unit of energy delivered, energy related greenhouse gas emission per unit GDP, and energy related greenhouse gas emission per capita. The selected indicators are used to measure progress towards sustainable development in the country

    Energy is an essential factor in overall efforts to achieve sustainable development. Countries striving to this end are seeking to reassess their energy systems with a view toward planning energy programmes and strategies in line with sustainable development goals and objectives. This paper summarizes the outcome of an international partnership initiative on indicators for sustainable energy development that aims to provide an analytical tool for assessing current energy production and use patterns at a national level. The proposed set of energy indicators represents a first step of a consensus reached on this subject by five international agencies-two from the United Nations system (the Department of Economic and Social Affairs and the International Atomic Energy Agency), two from the European Union (Eurostat and the European Environment Agency) and one from the Organization for Economic Cooperation and Development (the International Energy Agency). Energy and environmental experts including statisticians, analysts, policy makers and academics have started to implement general guidelines and methodologies in the development of national energy indicators for use in their efforts to monitor the effects of energy policies on the social, economic and environmental dimensions of sustainable development

    Full Text Available The rapid population growth leads to greater daily demand for energy, causing nations to diversify their portfolios and seek new sources of energy, including renewable to provide more energy. In a universe with seriously exhausted natural resources, severe urbanization, climate change and conflicts that go beyond borders, the issue of overpopulation unquestionably causes worldwide debates and can generate a snowball effect for the global economy or human society. Population’s increase in the nearby future will have a central role in challenges such as: global warming, air and water contamination, increase in the level of poverty, food scarcity, deforestation, desertification, health problems and resource shortages. The transformation into a sustainable environmental model, situated in a post-carbon economy, will imply setting barriers to industrial progress (will have to be sustainable and environmental friendly and also to population growth (will have to follow a normal pace. But, the level on vulnerability and uncertainty in the evolution of energy has been threatened lately by major events that took place all around the world. Security of supply, new geopolitical perspectives and ecological and sustainability issues are yet again on the bleeding line. Therefore, the goal of this theoretical article is to give an overview of the current situation concerning the role of energy in ecological sustainability. It expresses routes in which humans and enterprises can act in order to contribute to ecologically sustainable development. The subject of how we live on a congested planet represents the most critical sustainability of all. We are witnessing our current risks and we can also envision our possible, and particularly desirable, future: a steady human population, living and protecting the nature and planet, having finite needs of goods, services, or energy, and maintaining a healthy Earth for us and the animals that also depend on it.

    The development of globalised supply chains is a major challenge for sustainability. For several years, there has been discussion within the profession whether and how ergonomics and human factors can play a role. Based on our research, we have identified five major challenges from global supply chains especially related to the social aspects of sustainability: (1) criteria for social sustainability, (2) the role of key performance indicators in the management of supply chains, (3) the constant changes in supply chains, (4) the challenge in establishing participation, and (5) the development of agency and regulatory mechanisms. There are obviously no clear and simple solutions to these challenges. One possible avenue for progress might lie in acquiring a greater understanding of the challenges from global supply chains and developing a strategy which combines social and long-term business sustainability. Starting from such a basis, the next step would be to find ways for the ergonomics and human factors community to create international collaboration which can impact specific global supply chains.

    2017-01-01

    Sustainable economic growth and improvement of the social welfare depend upon the sufficient supply of energy resources, while the utilization of energy resources is one of the main factors of environmental degradation. This research is involved with development of a sustainable energy system model and a new method for sustainability assessment. This model represents the flow of energy from primary resources through processing, conversion, and end-use technologies in an optimization framework where the useful energy demand in various social and economic sectors is met. The impact of energy supply and consumption chain on the environment at each level of energy system is also embedded in the model structure. A multi-criteria analysis of changes is then applied and sustainable development indices of the whole system are concluded. Finally, effects of the energy subsidy policy and high economic growth rate on sustainability of the energy system in three scenarios are analyzed. Results demonstrate that energy subsidy decelerates the improvement rate of the total sustainability index. Also, when a high economic growth is accompanied with the energy subsidy this index reduces considerably. Results show that how penetration of renewable energy potentials changes the sustainability situation of energy systems. - Highlights: • Developing a new model for sustainable energy systems. • Presenting a new method for sustainability assessment of energy systems. • Optimizing the energy flow and capacity expansion of Hamedan energy system. • Utilizing an MCDA approach to obtain sustainability indices of the whole system. • Analysis of energy subsidy and high economic growth on energy sustainability.

    Ecologically neutral, cost efficient, without supply shortages, independent from foreign countries, risk- and waste-free - that is the image of an ideal future energy supply. But even if considerable ecological and economical improvements of various energy supply options can be achieved, the next generation of heat and power plants with the associated up- and down-stream parts of energy chains, will not comply with all such idealistic requirements. As research in the framework of the GaBE Project on 'Comprehensive Assessment of Energy Systems' has shown, among the reasons for this are the limited medium term potential of renewable energy sources, and the necessity to employ primarily non-renewable energy carriers for the emerging more efficient energy conversion processes.

    The economic survival of any nation depends upon its ability to produce and manage sufficient supplies of low-cost safe energy. The world's consumption of fossil fuel resources currently increasing at 3% per annum is found to be unsustainable. Projections of this trend show that mankind will exhaust all known reserves in the second half of the coming century. Governments, industrialists, commercial organizations, public sector departments and the general public have now become aware of the urgent requirements for the efficient management of resources and energy-consuming activities. Most organizations in the materials, manufacturing and retail sectors and in the service industries have also created energy management departments, or have employed consultants, to monitor energy consumption and to reduce wastage. Conversely, any sustained attempt to reduce rates of energy consumption even by as little as 0.1% per annum ensures relatively an eternal future supply as well as reduction on environmental and ecological effect. Thus, there is no long- term solution to energy flow problem other than systematic and effective energy management and the continuous application of the techniques of energy management. Essential energy management strategies in support of a sustainable energy- economy are discussed.

    2017-12-01

    Full Text Available The purpose of this article is to explore the role of multi-stakeholder initiatives (MSIs in sustainable supply chains. I argue that MSIs are needed to help establish and institutionalize the natural and social thresholds in which a sustainable supply chain must operate. While a multitude of MSIs relevant to supply chains already exist, they do not yet adequately address sustainability thresholds. Building on theory and literature, I elaborate on four interrelated roles for MSIs in this area: (1 providing learning platforms, (2 developing standards, (3 developing enforcement mechanisms, and (4 issuing labels and certifications. All four roles emphasize the need for supply chains to operate within the thresholds set by nature and society. Staying within thresholds is what distinguishes between sustainable and unsustainable supply chains. The four roles form part of a broader conceptual framework outlining a way forward for MSIs in sustainable supply chains. Different MSIs could address one or more of these roles. I argue that all MSIs must be developed with special attention to their input and output legitimacy. Stakeholders from both within and beyond the supply chain must be involved in developing and implementing a MSI for it to be viewed as legitimate. I note that the conceptual framework presented here is a starting point. It would benefit from further testing and refinement. For example, future work could add further specificity to the four roles I discuss. Future research could also focus on integrating economic thresholds for sustainable supply chains into the framework.

    Full Text Available The world’s habitat is being deteriorated despite of the precautions taken. Construction industry is among the industries which highly effect the environment adversely not only through its outputs but also through the construction process and its inputs. The main focus in dealing with the reduction of its footprint has been on sustainable building certificates which mainly analyse the output of the construction activies. There is need to analyse the construction supply chain as a whole and to embed sustainability dynamics in construction supply chain management. Lean construction project management contributes to the reduction of the environmental footprint of the construction industry, enabling reduction in waste, and increasing value added activities. For this reason, based on an in depth literature review, this paper analyses and establishes the principles of the integration of the sustainability dynamics into lean construction supply chain management.

    One of the major challenges of sustainable urban development is ensuring a sustainable energy supply while minimizing negative environmental impacts. The European Union Directive 2009/28/EC has set a goal of obtaining 20 percent of all energy from renewable sources by 2020. In this context, it is possible to consider the use of residues from forest maintenance, residues from livestock, the use of energy crops, the recovery of food waste, and residuals from agro-industrial activities. At the same time, it is necessary to consider the consequent environmental impact. In this paper an approach in order to evaluate the environmental compatibility has presented. The possibilities of national priorities for commissioning of power plants on biofuel and other facilities of distributed generation are discussed.

    This book starts out with the optimistic perspective that modern cities can indeed play a strategic role in the necessary pathway to sustainable development, with particular emphasis on the opportunities offered by local energy and environmental initiatives. Our study aims to demonstrate that an urban sustainability policy has many socio-economic benefits, while it also seeks to identify the critical success and failure factors of sustainable city innovations. After a comprehensive review of various opportunities and experiences, attention is focused particularly on renewable energy resources which may offer new potential for the active involvement of local authorities. The study also highlights major impediments regarding the adoption and implementation of renewable energies, in particular, the development of advanced energy-environmental technology in a world dominated by natural (public) monopolies and/or monopolistic competition elements. In this context both theoretical and empirical elements are discussed, as well as institutional aspects. The theory and methodology is tested by a thorough empirical investigation into local renewable energy initiatives in three European countries, viz. Greece, Italy and The Netherlands. Based on an extensive data base, various statistical models are estimated in order to identify the key elements and major driving forces of sustainable development at the city level. And finally, the study is concluded with a long list of applicable and operational policy guidelines for urban sustainability. These lessons are largely based on meta-analytic comparative studies of the various initiatives investigated. (orig.)

    In the United States, empirical information on the sustainability of commercial-scale egg production is lacking. The passage of state regulations specific to hen housing created urgency to better understand the effects of different housing systems on the sustainability of the egg supply, and stimulated the formation of a coalition, the Coalition for a Sustainable Egg Supply (CSES), to conduct research on this topic. The CSES is a multi-stakeholder group with 27 members, including food manufacturers, research institutions, scientists, restaurants, food service, retail food companies, egg suppliers, and nongovernmental organizations. A commercial-scale study was developed to better understand the effect of 3 housing systems (conventional cage, enriched colony, and cage-free aviary) on 5 areas related to a sustainable egg supply. These 5 sustainability areas represent effects on people, animals, and the environment: animal health and well-being, environment, food safety, worker health and safety, and food affordability. Five teams of scientists, each associated with a sustainability area, conducted an integrated field study at a commercial site in the upper Midwest through 2 flock cycles in 3 housing systems. This paper provides a brief overview of the CSES project to serve as an introduction for the papers that follow in this volume of Poultry Science. © The Author 2015.

    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

    A huge increase in energy use is expected in the coming decades – see the IEA’s ‘business as usual’/reference scenario below. While developed countries could use less energy, a large increase is needed to lift billions out of poverty, including over 25% of the world’s population who still lack electricity. Meeting demand in an environmentally responsible manner will be a huge challenge. The World Bank estimates that coal pollution leads to 300,000 deaths in China each year, while smoke from cooking and heating with biomass kills 1.3 million world-wide – more than malaria. The IEA’s alternative scenario requires a smaller increase in energy use than the reference scenario and is also less carbon intensive, but it still implies that CO2 emissions will increase 30% by 2030 (compared to 55% in the reference scenario). Frighteningly, implementing the alternative scenario faces “formidable hurdles” according to the IEA, despite the fact that it would yield financial savings for consumers that...

    The International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO), existing within IAEA Vienna decided to prepare energy and nuclear vision of 21st century. We were asked on behalf of AER Working Group F - 'Spent Fuel Transmutations' and INPRO IAEA collaborative project RMI 'Meeting energy needs in the period of raw materials insufficiency during the 21st century' to prepare material about the situations, reasons and expected time table concerning future nuclear fuel cycle closing and influences of fossil raw materials deficiencies, expected during the coming century. Material does not content, specially in the second part complete solution and partially is only formulating extremely complex problems of mutual interaction of technologies, raw materials availability and economy needs, together with political demands of non-proliferation of nuclear weapons and ecology, taking into account equal rights to have electricity and further services using nuclear energy.

    2006-01-01

    Rapid economic expansion in Malaysia over recent decades has led to a large growth in demand for electricity. Demand growth has put a strain on the ability of the economy to expand its electricity infrastructure capacity rapidly to meet the surge in demand. Over the next decade or two, assuming Malaysia will continue to grow at current growth rates of 4.0%, Malaysia will require enormous supply of electricity to meet demand growth. To congregate this challenge, Malaysia needs to consider the energy supply systems that can contribute to the long-term sustainability of economy in the future. Energy supply is critical to social and economic development, and they both have direct and indirect impacts on the environment. The idea of sustainable energy frequently focuses on renewable energy (RE) resources and consideration of these resources in meeting the energy requirements of Malaysia is given high priority in this paper. This paper will embrace the issue of electricity supply resources, technologies and energy policies in accommodating the economy towards energy sustainability over the long term, thus meeting immediate energy needs. It is also the intention of this paper to highlight new and existing RE technologies and their important roles in encouraging a sustainable electricity supply growth pattern in Malaysia. RE generation systems will begin to make significant contributions to new generation capacity installations. However, political and policy reform will have to occur at an unprecedented rate for this to materialise. Malaysia Vision 2020 envisions for a caring society to evolve as part of the country ambition of achieving developed nation status. A balanced growth using sustainable development principles is advocated in which today's needs are met without compromising the needs of future generation

    Full Text Available Background: The need for sustainable supply chain management has become a necessity given the growing impact of climate change and global warming. The South African (SA government is planning to implement a carbon tax in the future, which will present financial challenges for organisations already facing social and environmental difficulties. Objectives: The main objective of this article was to investigate the current sustainability reporting practices in supply chains of SA organisations. The focus was specifically on the supply chain sustainability practices of organisations listed in selected sectors on the Johannesburg Stock Exchange (JSE. A secondary objective was to investigate preparation efforts by SA companies for the impending carbon tax. Method: Data collected from sustainability and integrated annual reports of organisations in the sample were analysed using non-parametric statistical tests to compare sectors on the JSE and to compare companies listed on the socially responsible investment (SRI Index with those that are not. Results: The results showed that there is insufficient data for some of the sectors; however, there are differences in the supply chain and sustainability practices for the remaining sectors. There are also differences in these practices between SRI and non-SRI companies. The research also showed that companies are discussing important concepts relating to the implementation of the impending carbon tax. Research impact: SA organisations need to increase their focus on sustainable supply chain practices. Further investigation into the preparation efforts of companies to reduce their emissions and/or footprint and mitigate the impact of the impending carbon tax is necessary.

    At the U.N. Commission on Sustainable Development (CSD), the role of nuclear power for a carbon free emission supply of energy is now being recognized although with certain reticence or opposition. Such recognition is taking place at the current cycle of discussions devoted to sustainable energy, industrial development, atmospheric pollution and climate change issues. This paper focuses on the arguments and facts provided during CSD deliberations for considering nuclear energy as a valid option: all available energy sources will need to be considered for an adjustment to a world that requires much less carbon liberation to the environment; in the transportation sector, actions need to be urgently implemented for promoting cleaner fuels and more efficient vehicles; massive reduction of greenhouse gas emissions must be urgently implemented in order to mitigate the impacts of global warming; sustainable energy solutions for developed economies are not always adequate in developing countries; the development evolution requires specifically tailored solutions to conditions of large annual growth-rates of energy demand. Consequently, nuclear power will provide the answer to many of these problems. (Author)

    2004-01-01

    A sustainable energy supply will be based on renewable energies and it must use available resources efficiently. Earlier or later the energy supply will rely completely on renewable sources. A solar energy system that provides a reliable energy supply throughout the year includes the consistent use of local renewable energy sources (e.g. PV) wherever possible. Using Japan as a example it was shown that the vision of a full renewable energy supply, even with high shares of domestic sources is possible. Detailed simulations of such a system show that the PV systems play an important role delivering electricity at peak demand times. (authors)

    Security of energy supply was a major concern for OECD governments in the early 1970. Since then, successive oil crises, volatility of hydrocarbon prices, as well as terrorist risks and natural disasters, have brought the issue back to the centre stage of policy agendas. In this paper, the author discusses the problem of energy supply security. Can security of supply be measured? What is the role of government and of nuclear energy? And what are measures for ensuring security of supply? (A.L.B.)

    The continued growth of the world's population makes continued economic growth indispensable. If economic growth were to stop, this would be an invitation to fighting for distribution. In the absence of progress, social improvements become utopian. In the absence of growth, at least for the next fifty years, there will be no means by which to correct even the worst inequalities in the world. It is probably not exaggerating to assume that the whole of mankind could not survive the next fifty years in the absence of the results derived from growth. At any rate, the attitudes and developments in the highly industrialized countries and in the industrializing countries will be decisive. Here is where the keys will be found to opening for the poorest the door to a more promising future and, at the same time, reducing the deadly threat to one's own existence. Economic growth can exist only if there is energy growth, and nuclear power is the only available source able to satisfy in an economic way the demand for energy, which will continue to rise on the medium term.

    2011-07-01

    Traditional village houses now use renewable materials and energy sources and this paper presents the intrinsic harmony of these buildings' greening and their sustainability. The paper covers building technical systems, sustainable energy supply, and the importance of renewable raw materials (RMS) for sustainable development. This study investigated the role of building dynamic behavior and optimized energy efficiency in reducing thermal loads significantly. A preliminary design for sustainable energy efficient settlements with net zero energy buildings is proposed and a comprehensive multidisciplinary engineering study was done which identified the technical feasibility of sustainable village energy and water supplies using solar or wind technologies. Overall, through analysis of sustainability definitions and possible ways to achieve sustainability, the study demonstrated that this can only be brought about by interdisciplinary interaction and finding the right balance between materiality and spirituality, science and art, and between technological development and concern for cultural and other human values.

    Renewable energy offers the possibility of providing a complete, sustainable energy infrastructure without anthropogenic emission of CO2. Large-scale implementation of renewable technologies would eliminate the need to develop and implement sequestration systems, by reducing the use of, and ultimately eliminating fossil based energy production. Renewable energy also offers energy security because indigenous resources are sufficient. The major renewable energy systems include phovoltaics (solar cells), solar thermal (electric and thermal), wind, biomass (plants and trees), hydroelectric, ocean, and geothermal. Given the intermittent nature of solar energy, only those energy systems that are coupled to an energy storage technology will be viable. Among the energy storage technologies are hydrogen, batteries, flywheels, superconductivity, ultracapacitors, pumped hydro, molten salts (for thermal storage), and compressed gas. One of the most versatile energy storage systems and the best energy carrier for transportation is hydrogen. This talk will review some of the basic renewable energy systems, present possible pathways for the implementation of hydrogen into the energy infrastructure and offer research areas that need to be addressed to increase the viability of these renewable energy technologies.

    Full Text Available With the expansion of the study about green logistics, sustainable supply chain management (SSCM has appeared as a new concept in current economic circumstance. This paper studies the sustainability optimization of enterprise logistics network from a strategic perspective and proposes a multiobjective sustainable logistics optimization model considering three dimensions of sustainability: economy, environment, and society. In this model, the environment factor was measured with a Life Cycle Assessment (LCA method based on Chinese Life Cycle Database (CLCD, while for social factors, Sustainability Reporting Guidelines (GRI are utilized to quantify the social performance. Moreover, the model was solved with an adapted version of the ε-constraint method named augment constraint algorithm (AUGMENCON through GAMS software. The numerical experiment results of a computer manufacturer supply chain show that the proposed model is able to integrate all dimensions of sustainability and simultaneously prove the capability of AUGMENCON in providing a set of trade-off solutions for the decision makers to make different decisions under different environment and social requirements.

    Energy is often known as the catalyst for development. Globally, the per capita consumption of energy is often used as a barometer to measure the level of economic development in a particular country. Realizing the importance of energy as a vital component in economic and social development, the government of Malaysia has been continuously reviewing its energy policy to ensure long-term reliability and security of energy supply. Concentrated efforts are being undertaken to ensure the sustainability of energy resources, both depletable and renewable. The aim of this paper is to describe the various energy policies adopted in Malaysia to ensure long-term reliability and security of energy supply. The role of both, non-renewable and renewable sources of energy in the current Five-Fuel Diversification Strategy energy mix will also be discussed. Apart from that, this paper will also describe the various alternative energy and the implementation of energy efficiency program in Malaysia

    2011-01-01

    In many rural areas, poor people still depend on wood and other biomass fuels for most of their household and income-generating activities. The difficult, time-consuming work of collecting and managing traditional fuels is widely viewed as women's responsibility, which is a factor in women's disproportionate lack of access to education and income, and inability to escape from poverty. Therefore, it is important for energy access programs to have a special focus on women. New options for energy access and sustainable livelihoods, like small-scale biofuels production, can have dramatic benefits for rural women, and their families and communities. Energy development, as both a driving force and a consequence of such tremendous changes, has had profound impact on economic, social, and environmental development. Rural energy has always been a critical issue due to years of energy shortage for both households and industries. Biomass, for long time, has been the only available fuel in many rural areas. The situation in rural areas is even more critical as local demand for energy outstrips availability and the vast majority of people depend on non-commercial energy supplies. Energy is needed for household uses, such as cooking, lighting, heating; for agricultural uses, such as tilling, irrigation and post-harvest processing; and for rural industry uses, such as milling and mechanical energy and process heat. Energy is also an input to water supply, communication, commerce, health, education and transportation in rural areas. (author)

    Global supply chains play a critical role in many of the most pressing environmental stresses and social struggles identified by the United Nations’ Sustainable Development Goals (SDGs). Responding to calls from the global community, companies are adopting a variety of voluntary practices to improve the environmental and/or social management of their suppliers’ activities. We develop a global survey of 449 publicly listed companies in the food, textile, and wood-products sectors with annual reports in English to provide insight into how the private sector contributes to advancing the SDGs via such sustainable-sourcing practices. We find that while 52% of companies use at least one sustainable-sourcing practice, these practices are limited in scope; 71% relates to only one or a few input materials and 60.5% apply to only first-tier suppliers. We also find that sustainable-sourcing practices typically address a small subset of the sustainability challenges laid out by the SDGs, primarily focusing on labor rights and compliance with national laws. Consistent with existing hypotheses, companies that face consumer and civil society pressure are associated with a significantly higher probability of adopting sustainable-sourcing practices. Our findings highlight the opportunities and limitations of corporate sustainable-sourcing practices in addressing the myriad sustainability challenges facing our world today. PMID:29440420

    It costs as much to heat the pot as to fill it. This old African proverb illustrates the energy-problems faced by majority of the world, who live in the villages and urban slums of developing countries, such as Pakistan. For a majority of them, the real energy-crisis is a daily scramble to find wood to cook meals and nearly 90% of their domestic energy demands are derived from wood. This essential resource, however, is threatened. The developing world is facing crisis of a critical shortage of firewood as serious as the petroleum-crisis. The shortage of firewood is resulting its soaring prices; a growing economic burden on rural poor; the wasteful burning of animal dung; and an ecologically disastrous and potentially irreversible spread of treeless landscapes.

    Full Text Available Anthropogenic emissions likely pose serious threat to the stability of our environment; immediate actions are required to change the way the earth’s resources are consumed. Among the many approaches to mitigation of environmental deterioration being considered, the processes for designing, sourcing, producing and distributing products in global markets play a central role. Considerable research effort is being devoted to understanding how organisational initiatives and government policies can be structured to facilitate incorporation of sustainability into design and management of entire supply chain. In this paper, we review the current state of academic research in sustainable supply chain management, and provide a discussion of future direction and research opportunities in this field. We develop an integrative framework summarising the existing literature under four broad categories: (i strategic considerations; (ii decisions at functional interfaces; (iii regulation and government policies; and (iv integrative models and decision support tools. We aim to provide managers and industry practitioners with a nuanced understanding of issues and trade-offs involved in making decisions related to sustainable supply chain management. We conclude the paper by discussing environmental initiatives in India and the relevance of sustainability discussions in the context of the Indian economy.

    Full Text Available This paper presents an overview on the sustainability of ancient water supply systems in Jerusalem from the Chalcolithic period (4500–3200 B.C. until the present time. Archaeological evidences and landscape settings were applied utilizing all available and accessible literature relevant to ancient water resources management in Jerusalem. Irrigated agriculture was practiced for many centuries in this region, hence sustainable water supply facilities were erected, including well developed aqueducts, water harvesting pools and irrigation channels for water storage and landscaping purposes. To cope with seismic events, soil subsidence and water leakage, ancient water engineers and architects applied innovative construction methods for the erection of water pools, channels and aqueduct systems. Ancient water supply systems in Jerusalem are valuable treasures of past civilizations and crucial urban environmental facilities and their protection is consistent with sustainable development principles. Effective environmental assessment as a decision-making process for sustainable development can be applied to preserve threatened ancient water facilities from major development proposals and urban infrastructure projects in Jerusalem.

    2017-10-01

    Full Text Available Energy efficiency represents a key resource for economic and social development, providing substantial benefits to different stakeholders, ranging from the entities which develop energy efficient measures to everyone in society. In addition to cost savings, multiple benefits can be achieved by supporting a better alignment between energy issues and strategic business priorities: e.g., improved competitiveness, profitability, quality, etc. Thus, energy efficiency can be a strategic advantage, not just a marginal issue, for companies. However, most firms, especially small and medium enterprises (SMEs, face many problems and, in some cases, hostility when trying to effectively implement energy efficiency actions. The most dominant barriers are the access to capital and the lack of awareness (especially in terms of life cycle cost effects. The supply chain viewpoint represents one of the main opportunities for overcoming those barriers and improving energy performance even for weaker companies. Since the current literature on energy efficiency and practical approaches to ensure energy efficiency mainly focus on energy performance on a single-firm basis, this paper aims to provide a systematic review of papers on the integration of energy efficiency in supply chain design and management published in academic journal, thereby defining potential research streams to close the gaps in the literature. A number of literature reviews have been published focusing on specific aspects of sustainable or on green supply chain management; however, to the best of our knowledge, no review has focused on the energy efficiency issue. Firstly, the present paper shows how considering energy consumption in supply chain management can contribute to more energy-efficient processes from a systemic point of view. Then, the review methodology used is defined and the sampled papers are analyzed and categorized based on the different approaches they propose. From these

    An efficient influence on traffic can generally not be achieved by an individual instrument or by few instruments. Numerous coordinated measures from all domains of traffic policy (Investment policy, price policy, order policy, organisational measures, public affairs work) are required instead. Thus it can be guaranteed that counter-productive effects do not impede reaching the desired targets. The effects of individual measures must supplement and strengthen each other. These synergy effects allow keeping the intensity of individual measures, such as the price policy at a low level and limiting adaptation shocks. A tendency scenario and sustainability scenario until 2020 are defined for a quantitative analysis of the effects of such measure bundle. The period from 2020 until 2050 is merely considered in terms of quality. (orig.) [German] Eine wirksame Verkehrsbeeinflussung kann grundsaetzlich nicht durch ein einzelnes Instrument oder durch wenige Instrumente erreicht werden. Vielmehr ist hierfuer ein abgestimmtes Buendel von Massnahmen aus allen verkehrspolitischen Bereichen (Investitionspolitik, Preispolitik, Ordnungspolitik, organisatorische Massnahmen, Oeffentlichkeitsarbeit) notwendig. Dadurch wird gewaehrleistet, dass die Erreichung der angestrebten Ziele nicht durch gegenlaeufige Wirkungen behindert wird. Die Wirkungen einzelner Massnahmen muessen sich ergaenzen und gegenseitig verstaerken. Solche Synergieeffekte wiederum gestatten es, die Intensitaet von einzelnen Massnahmen, z.B. der Preispolitik, vergleichsweise gering zu halten und damit Anpassungsschocks zu begrenzen. Zur quantitativen Analyse der Wirkungen solcher Massnahmenbuendel werden ein Trendszenario und ein Nachhaltigkeitsszenario bis 2020 definiert. Fuer den Zeitraum 2020 bis 2050 werden lediglich qualitative Ueberlegungen angestellt. (orig.)

    2009-01-01

    This paper explores the possibilities for reducing future energy use for eating to a sustainable level. A backcasting approach is used to generate an image of the future where energy use for eating is 60% lower in 2050 than in 2000. The currently known potential to reduce energy use in the food supply system for producing, transporting, storing, cooking and eating food is explored and described in terms of a number of distinct changes that are numbered consecutively and presented in both a quantitative and qualitative way. Sweden is used as the case and all data regarding energy use apply for Swedish conditions. An exercise like this illustrates the possible outcome of taking sustainability seriously. If sustainability is to be achieved, some images of the future are needed so that potential targets can be identified. This paper does not present forecasts, but illustrates the kind of changes needed in order to achieve sustainable energy use in the food system.

    A new energy paradigm, consisting of greater reliance on renewable energy sources and increased concern for energy efficiency in the total energy lifecycle, has accelerated research in energy-related technologies. Due to their ubiquity, magnetic materials play an important role in improving the efficiency and performance of devices in electric power generation, conversion and transportation. Magnetic materials are essential components of energy applications (i.e. motors, generators, transformers, actuators, etc.) and improvements in magnetic materials will have significant impact in this area, on par with many ``hot'' energy materials efforts. The talk focuses on the state-of-the-art hard and soft magnets and magnetocaloric materials with an emphasis on their optimization for energy applications. Specifically, the impact of hard magnets on electric motor and transportation technologies, of soft magnetic materials on electricity generation and conversion technologies, and of magnetocaloric materials for refrigeration technologies, will be discussed. The synthesis, characterization, and property evaluation of the materials, with an emphasis on structure-property relationships, will be examined in the context of their respective markets as well as their potential impact on energy efficiency. Finally, considering future bottle-necks in raw materials and in the supply chain, options for recycling of rare-earth metals will be analyzed.ootnotetextO. Gutfleisch, J.P. Liu, M. Willard, E.

    2009-01-01

    The growing demand in energy and concern about depleting natural resources and global warming has led states worldwide to consider alternatives to the use of fossil fuel for energy production. Several countries especially in Europe have already increased their renewable energy share 6-10%, expected to increase to 20% by the year 2020. For Egypt excellent resources of wind and solar energy exist. The article discusses perspectives of wind energy in Egypt with projections to generate ∼ 3.5 GWe by 2022, representing ∼ 9% of the total installed power at that time (40.2 GW). Total renewable (hydro + wind + solar) are expected to provide ∼ 7.4 GWe by 2022 representing ∼ 19% of the total installed power. Such a share would reduce dependence on depleting oil and gas resources, and hence improve country's sustainable development

    Successful delivery of the United Nations sustainable development goals and implementation of the Paris Agreement requires technologies that utilize a wide range of minerals in vast quantities. Metal recycling and technological change will contribute to sustaining supply, but mining must continue and grow for the foreseeable future to ensure that such minerals remain available to industry. New links are needed between existing institutional frameworks to oversee responsible sourcing of minerals, trajectories for mineral exploration, environmental practices, and consumer awareness of the effects of consumption. Here we present, through analysis of a comprehensive set of data and demand forecasts, an interdisciplinary perspective on how best to ensure ecologically viable continuity of global mineral supply over the coming decades.

    2005-01-01

    Pakistan is an energy deficient country that heavily relies on imports of fossil fuels to meet its energy requirements. Pakistan is facing severe energy challenges -indigenous oil and gas reserves are running out, energy demand is rapidly increasing, gap between demand and supply is growing, concerns about secure supply of energy are increasing and fuel cost is rising at an unprecedented rate. For sustainable development, it is crucial to ensure supply of adequate, consistent and secure supply of energy. Renewable energy resources that are sustainable are abundantly available in Pakistan in various forms such as hydel power, solar energy, wind power and biomass. To address the growing energy challenges, it has become inevitable for the country to diversify its energy market through harnessing renewable energy resources. It has been found that hydel power is one of the most significant renewable energy sources that can help Pakistan address the present as well as future energy challenges. It has been identified that solar water heating is another ready to adopt renewable energy technology that alone has the potential to meet as much as 12-15% of the country's entire energy requirements.

    As an attempt occurred against a French oil tanker in the Persian Gulf (in 2002), and showed that security of oil supplies is not only related to oil shock or to political environment such as the Cold War, this article discusses issues of security for European energy supplies. It first addresses the situation and the evolution of energy needs and resources in the World and in Europe: predictions of evolution of consumption and production, major role of fossil fuels in the European consumption. It discusses the outage risks: the supply security can be analysed with respect to consumption per sector, per usage or per energy product, and Europe must face three major risks (no more hydrocarbon resources at a reasonable cost, economic risk due to market volatility, geopolitical risk). The next part discusses the perspective of a European strategy. It identifies several elements of choice for Europe in terms of energy demand management, of opening up to competition of electricity and gas markets. It discusses European ambitions in terms of supply security: need of a community framework, actual propositions of a directive for oil and gas

    In the available contribution the author directs the view of the complexity as a neglected peculiarity of the large technology. Many elements of the energy conflicts and dangers of the energy supply are explainable only by the uncritical attitudes in relation to the associated and not sufficiently solvable complexity problems. The criticism to it is directed not alone against the atomic energy, but more generally against the heedless technique philosophy of the power suppliers

  7. Indirect Potable Reuse: A Sustainable Water Supply Alternative

    Clemencia Rodriguez

    2009-03-01

    Full Text Available The growing scarcity of potable water supplies is among the most important issues facing many cities, in particular those using single sources of water that are climate dependent. Consequently, urban centers are looking to alternative sources of water supply that can supplement variable rainfall and meet the demands of population growth. A diversified portfolio of water sources is required to ensure public health, as well as social, economical and environmental sustainability. One of the options considered is the augmentation of drinking water supplies with advanced treated recycled water. This paper aims to provide a state of the art review of water recycling for drinking purposes with emphasis on membrane treatment processes. An overview of significant indirect potable reuse projects is presented followed by a description of the epidemiological and toxicological studies evaluating any potential human health impacts. Finally, a summary of key operational measures to protect human health and the areas that require further research are discussed.

  9. Building sustainable supply chains: consumer choice or direct management?

    Energy Technology Data Exchange (ETDEWEB)

    Hebditch, David; Blackmore, Emma

    2012-06-15

    Putting a 'carbon label' on products to show how much carbon dioxide is emitted during their production, transport and disposal has been heralded as a powerful route to sustainability within companies' supply chains. Several leading firms have joined the Carbon Trust carbon labelling scheme over the past five years, including UK-based retail giant Tesco, which as early as 2007 promised to use carbon labels on all its products. But earlier this year, the multinational said it was dropping carbon labels and instead directly managing its supply chains. Many other companies are similarly choosing direct management over consumer choice as the most effective route to emission reductions. In so doing, they are shouldering greater responsibility for the emissions and impacts of their supply chains. But environmental concerns must not be allowed to trump development needs and companies must not unfairly disadvantage smaller-scale producers in developing countries.

  10. Nuclear fuel: sustainable source of energy or burden on society?

    International Nuclear Information System (INIS)

    Williams, T.; Klaiber, G.

    2007-01-01

    In the past, the question concerning the sustainability of a resource primarily addressed its finite nature. Accordingly, electricity production using renewable energies was clearly sustainable. Contrasting this are systems based on oil, gas, coal or uranium. However, from the perspective of 'neo-sustainability' being analyzed today, this assessment appears less clear-cut, especially in light of the definition of sustainability as provided by the Brundtland report. Nowadays, the depletion time of fuel resources is thus not the only significant aspect, but factors such as efficiency, ecofriendliness and social responsibility also figure in. The nuclear fuel supply is analyzed from a sustainability perspective. After a short description of the supply chain, each of the most important aspects of sustainability are related to the individual stages of the supply chain and evaluated. This method aims at answering the question concerning to what extent nuclear fuel is a sustainable source of energy. Although the recycling of fissile materials from reprocessing and the deployment of advanced reactors are key factors as regards the issue of sustainability, these topics are deliberately only touched on. The main focus lies on the sustainability of the nuclear fuel cycle as it is currently utilized in light water reactors, without discussing the subject of reprocessing. (orig.)

    2017-08-01

    Full Text Available This paper aims to analyse how the publications in Brazil are considering the relationship between sustainability and supply chain management. For this end, a literature review was carried out in 120 Brazilian academic journals in which 124 papers were identified, from 2008 until 2013. When considering the Triple Bottom Line approach, the results show that sustainability research in Brazil is focusing on the environmental dimension and SCM research is focusing on the economic dimension. Additional inputs are provided by integrating the governance dimension in the analysis to underline which actions and policies are discussed in Brazil at a corporate level. To support the results a consultation of experts in the field of sustainability in Brazil was fulfilled, and three case examples are presented to explain some of the research results. The findings on publications in Brazil contrast with international studies, particularly on the topic of social performance and management in supply chains. One of the main conclusions is that there are large opportunities to increase publications about sustainability and SCM in the country and that Brazil presents some specificities in the field that researchers and managers shall consider.

    In the future as well as in the past, and in particular in the next decade a considerable increase in electrical energy demand can be expected. To satisfy this demand in a reliable and sufficient manner will force the utilities to invest large sums of money for the operation and the extension of power generation and distribution plants. The size of these investments justifies the search for more and more comprehensive and at the same time more detailed planning methods. With the help of system analysis a planning model for the electricity supply industry of a major supply area will be designed. (orig./RW) [de

    Directory of Open Access Journals (Sweden)

    J. D. S. Cullis

    2018-02-01

    Full Text Available Many countries, like South Africa, Australia, India, China and the United States, are highly dependent on coal fired power stations for energy generation. These power stations require significant amounts of water, particularly when fitted with technology to reduce pollution and climate change impacts. As water resources come under stress it is important that spatial variability in water availability is taken into consideration for future energy planning particularly with regards to motivating for a switch from coal fired power stations to renewable technologies. This is particularly true in developing countries where there is a need for increased power production and associated increasing water demands for energy. Typically future energy supply options are modelled using a least cost optimization model such as TIMES that considers water supply as an input cost, but is generally constant for all technologies. Different energy technologies are located in different regions of the country with different levels of water availability and associated infrastructure development and supply costs. In this study we develop marginal cost curves for future water supply options in different regions of a country where different energy technologies are planned for development. These water supply cost curves are then used in an expanded version of the South Africa TIMES model called SATIM-W that explicitly models the water-energy nexus by taking into account the regional nature of water supply availability associated with different energy supply technologies. The results show a significant difference in the optimal future energy mix and in particular an increase in renewables and a demand for dry-cooling technologies that would not have been the case if the regional variability of water availability had not been taken into account. Choices in energy policy, such as the introduction of a carbon tax, will also significantly impact on future water resources, placing

    We can expect to see the peak of world oil production very soon. Some say that we can see that peak now in our rear-view mirrors as we drive into an oil-poor future. Natural gas already is in short supply in North America. Nuclear energy must make up the lion's share of the world's energy deficit. This paper examines, in very general terms, the implications of today's shifting prospects for nuclear energy, as it exists today, and how those prospects might develop in the future. The time span under consideration is the remainder of the 21st century. (author)

  18. Sustainability Of Electricity Supply Technologies under German Conditions: A Comparative Evaluation

    Hirschberg, S; Dones, R.; Heck, T.; Burgherr, P.; Schenler, W.; Bauer, C.

    2004-12-01

    On behalf of the International Committee on Nuclear Technology (ILK) the Paul Scherrer Institut carried out a comparative study addressing the sustainability of electricity supply technologies operating under German-specific conditions. The general objective of this analysis was to provide a support for the formulation of ILK position on the sustainability of various electricity supply technologies, with special emphasis on nuclear energy. The evaluation covers selected current fossil, nuclear and renewable technologies, which are representative for the average conditions in Germany. Two methods of indicator aggregation were employed, i.e. estimation of total (internal and extemal) costs and Multi-criteria Decision Analysis (MCDA). Use of MCDA is motivated by acknowledgement of the role of value judgements in decision-making. Both total costs and MCDA-based technology-specific total scores are useful comparative indicators of sustainability. Sustainability perspective implies a balanced (equal) importance assignment to economic, ecological and social aspects. In summary, this study provides a framework for systematic evaluation of sustainability of energy systems. Refinements of the methodology and specific indicators are feasible. Options for future applications include direct involvement of stakeholders, and evaluations of future technologies and of supply scenarios combining the various candidate technologies. Tools supporting such analyses have been developed by PSI and can be adjusted to the needs of country-specific applications. (author)

    evaluate its robustness against the background of the different energy landscapes in the world. Striking a balance between the priorities of energy policy is, however, difficult in an EU where a wide diversity of energy mixes and import dependencies prevails, and where foreign policy and security approaches are even more diverse. The current weaknesses of the EU energy policy, which is in essence comprised of an internal market and competition policy, a nascent sustainable energy policy and an absent security of supply policy will either be addressed under the mounting pressures of the outside world or will derail any hopes of a common energy policy. The main challenges to this common policy are thus political, both internally and externally.

  20. Sustainable desalination using ocean thermocline energy

    KAUST Repository

    2017-09-22

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

    With 1.4 billion people lacking electricity to light their homes and provide other basic services, or to conduct business, and all of humanity (and particularly the poor) are in need of a decarbonized energy system can close the energy access gap and protect the global climate system. With particular focus on addressing the energy needs of the underserved, we present an analytical framework informed by historical trends and contemporary technological, social, and institutional conditions that clarifies the heterogeneous continuum of centralized on-grid electricity, autonomous mini- or community grids, and distributed, individual energy services. We find that the current day is a unique moment of innovation in decentralized energy networks based on super-efficient end-use technology and low-cost photovoltaics, supported by rapidly spreading information technology, particularly mobile phones. Collectively these disruptive technology systems could rapidly increase energy access, contributing to meeting the Millennium Development Goals for quality of life, while simultaneously driving action towards low-carbon, Earth-sustaining, energy systems.

    2010-01-01

    Commercialization efforts to diffuse sustainable energy technologies (SETs) have so far remained as the biggest challenge in the field of renewable energy and energy efficiency. Limited success of diffusion through government driven pathways urges the need for market based approaches. This paper reviews the existing state of commercialization of SETs in the backdrop of the basic theory of technology diffusion. The different SETs in India are positioned in the technology diffusion map to reflect their slow state of commercialization. The dynamics of SET market is analysed to identify the issues, barriers and stakeholders in the process of SET commercialization. By upgrading the 'potential adopters' to 'techno-entrepreneurs', the study presents the mechanisms for adopting a private sector driven 'business model' approach for successful diffusion of SETs. This is expected to integrate the processes of market transformation and entrepreneurship development with innovative regulatory, marketing, financing, incentive and delivery mechanisms leading to SET commercialization.

    This article is based on an exploratory study which analyses some of the earliest multi-actor sustainable supply chain governance systems in order to answer the key research questions: Which strategies and instruments do governments - national and supranational - apply in advancing sustainable production and consumption in global supply chains; and What is known about the effectiveness of these strategies and instruments? The study focuses on two supply chains with the longest history of addressing imports from developing countries (tropical timber and coffee). These two supply chains are compared with two supply chains that are gaining increasing attention: - cocoa and tea. The study shows that the two most 'mature' global sustainable supply chains are market led in issuing voluntary certification and that buying certified products is starting to become mainstream and increasingly effective. The sustainable supply chains for tea and cocoa are more recent developments but may develop faster because of the lessons learnt in sustainable supply chains developed earlier. [nl

    Chae, Kyu Nam

    1995-02-01

    An energy demand and supply analysis is carried out to establish the future nuclear energy system of Korea in the situation of environmental restriction and resource depletion. Based on the useful energy intensity concept, a long-term energy demand forecasting model FIN2USE is developed to integrate with a supply model. The energy supply optimization model MESSAGE is improved to evaluate the role of nuclear energy system in Korean long-term energy supply strategy. Long-term demand for useful energy used as an exogeneous input of the energy supply model is derived from the trend of useful energy intensity by sectors and energy carriers. Supply-side optimization is performed for the overall energy system linked with the reactor and nuclear fuel cycle strategy. The limitation of fossil fuel resources and the CO 2 emission constraints are reflected as determinants of the future energy system. As a result of optimization of energy system using linear programming with the objective of total discounted system cost, the optimal energy system is obtained with detailed results on the nuclear sector for various scenarios. It is shown that the relative importance of nuclear energy would increase especially in the cases of CO 2 emission constraint. It is concluded that nuclear reactor strategy and fuel cycle strategy should be incorporated with national energy strategy and be changed according to environmental restriction and energy demand scenarios. It is shown that this modelling approach is suitable for a decision support system of nuclear energy policy

    The problem of the extent to which new nuclear power plants are to be added, or the possibility of a complete ban on nuclear power in the Federal Republic of Germany, is now very much under discussion again. On the basis of the study published by the Conservation Commission of the World Energy Conference, 'World Energy - Looking Ahead to 2020,' whose findings are probably still on the conservative side, it is demonstrated that disastrous conditions will arise in most areas of the world unless the energy requirement can be met. There is still time to develop solutions by means of today's technologies and resources in order to ensure the long term continuity of energy supply. However, this will not be possible without the immediate and undisturbed expansion of nuclear energy, including the use of breeder reactors at the earliest possible date. In view of these perspectives there is no reason why the expansion of energy supply worldwide should not be assigned the same priority as the development of all-destructive weapons systems. (orig.)

    , Beijing, Shanghai, and Tokyo. The approach is applied to measure the majority of indirect energy flows or the energy embodied in the flows of goods and services involving the residents of those cities. Since the function of cities is to serve the lives of the residents, indirect energy consumption could be regarded as being of equal importance as that of direct energy use. The essence of embodied energy is that an indirect reflection upon behavior following direct energy consumption. It can illustrate how a city relies on the outside, for example other cities, countries, etc. and provides some interesting information that cannot be easily drawn from the direct energy demand. The study reveals that the indirect energy demand is more significant than the direct energy demand in Bangkok, Shanghai, and Tokyo, while direct energy demand is greater than the indirect energy demand in Beijing. This can be explained by the fact that Bangkok, Shanghai, and Tokyo have a greater reliance upon the outside in terms of energy demand. The Long-range Energy Alternative Planning (LEAP) system has been selected to perform Bangkok energy modeling. In a Bangkok case study a range of policy interventions are selected and how these would change the energy development in Bangkok by the year 2025 is examined. Different policies can be grouped by the sectors analyzed. The only supply-side policy considered meets an existing target of having 10% of electricity generated from renewable sources. The study period for the model started in 2005 and ends in 2025, with the year 2000 taken as the base year. The proposed scenarios were evaluated using the MCDM approach to rate their sustainability. Team members found that this method provided a methodology to help decision-makers to systematically identify management objectives and priorities.

  16. Water Use of Fossil Energy Production and Supply in China

    2017-07-01

    Full Text Available Fossil energy and water resources are both important for economic and social development in China, and they are tightly interlinked. Fossil energy production consumes large amounts of water, and it is essential to investigate the water footprint of fossil energy production (WFEP in China. In addition, fossil energy is supplied to consumers in China by both domestic and foreign producers, and understanding the water footprint of fossil energy supply (WFES is also highly significant for water and energy development programs in the long-term. The objectives of this paper were to provide an estimation of the blue component of WFEP and WFES in China for the period from 2001 to 2014, and to evaluate the impact on water resources from energy production, the contribution of internal and external WFES, and water-energy related issues of the international energy trade by applying water footprint analysis based on the bottom-up approach. The results indicate that generally, the WFEP and WFES in China both maintained steady growth before 2013, with the WFEP increasing from approximately 3900 million m3/year to 10,400 million m3/year, while the WFES grew from 3900 million m3/year to 11,600 million m3/year. The fossil energy production caps of the 13th Five Year Plan can bring the water consumed for fossil energy production back to a sustainable level. Over the long-term, China’s energy trade plan should also consider the water and energy resources of the countries from which fossil energy is imported.

  1. Nuclear energy and sustainability in Latin America

    International Nuclear Information System (INIS)

    Sterner, Thomas

    1991-01-01

    The concept of sustainability has been given numerous interpretations, some overlapping or complementary, some contradictory. Thus it is difficult to judge whether the nuclear industry does, or does not, meet sustainability criteria; particularly as the present nuclear technologies are not renewable. Uranium resources appear to be of the same order of magnitude as oil and gas resources. This implies that they are a transitional source of energy. There are also other potential arguments against the sustainability of nuclear power: its pollution, risks and costs. Environmental damage may come from various parts of the nuclear fuel cycle. Two types of risk will be discussed: first the risk of major accidents and thereby exceptional environmental damage, and second the risks associated with the proliferation of nuclear weapons. Each of these factors, as well as the pure economic cost of nuclear electricity, ought to be compared to the environmental damage, risks and costs of the available alternatives. Only the Latin American experience will be considered. For example, the need for Mexico to use nuclear power when it has large oil and gas supplies, is considered. (author)

    The Molybdenum-99/Technetium-99m ( 99 Mo/ 99m Tc) supply disruptions occurred in the recent years prompted the European Commission and industry to establish in 2012 a European Observatory on the Supply of Medical Radioisotopes, aimed at bringing together all relevant information to the decision makers in the European Union (EU) institutions and national governments in order to assist them in defining strategies as well as policies for their implementation. The Observatory follows the Organisation for Economic Co-operation and Development/Nuclear Energy Agency-OECD/NEA principles established by the High Level Group on the Security of Supply of Medical Radioisotopes (HLG-MR), of which the European Commission is a Member, and focuses on the specificities of their implementation in the EU, recognizing at the same time that the supply is of a global nature and requires broader international cooperation. The Observatory has four general strategic objectives: to support a secure 99 Mo/ 99m Tc supply across the European Union, ensure that the issue of 99 Mo/ 99m Tc supply is given high political visibility, encourage the creation of a sustainable economic structure of the supply chain and establish periodic reviews of the supply capacities and demand.

    Full Text Available Because of the importance of water supply for the sustainability of urban areas, and due to the significant consumption of energy with prices increasing every day, an alternative solution for sustainable energy supply should be sought in the field of Renewable Energy Sources (RES. An innovative solution as presented in this paper has until now not been comprehensively analyzed. This work presents the solution with the application of a (Photovoltaic PV generator. The main technological features, in addition to the designing methodology and case study are presented in this paper. The critical period approach has been used for the first time for system sizing. The application of this sizing method provides a high reliability of the proposed system. The obtained results confirm the assumption that the PV generator is a promising energy sustainable solution for urban water supply systems. The service reservoir, which acts as water and energy storage for the proposed system, provides the basis for a sustainable solution of water and energy supply. In accordance with the proposed, the reliability of such system is high. This concept of energy supply operation does not generate any atmospheric emission of greenhouse gases, which contributes significantly to the reduction of the impacts of climate changes. The proposed solution and designing methodology are widely applicable and in accordance with the characteristics of the water supply system and climate.

  9. Energy supply security and geopolitics: A European perspective

    Correlje, Aad; Linde, Coby van der

    2006-01-01

    The security of energy supply to the EU is examined in the context of two storylines. Markets and Institutions exemplifies an economically and politically integrated, multilateral world with effective institutions and markets. Regions and Empires involves a world broken up in rival political and economic blocks, competing for resources and markets via political, economic and military power. It is shown that these storylines have a significant impact on the development of the energy market, on the way in which energy supply may be secured and on the effect and applicability of the several types of instruments available. The current EU is geared towards enlargement and a deepening of economic integration, based on the tenets of the post-1945 multilateral world system. The present world tends towards Regions and Empires and suggests that the EU may have to reorient its energy security policy. Energy policy must become an integral part of EU external trade and foreign relations and security policy. The EU should develop its own strategy, actively investing in dialogues with producer countries in the Persian Gulf and Africa and with Russia. Sustainable prosperity and governance in these regions will support EU energy security. (author)

    China is fueling its phenomenal economic growth with huge quantities of coal. The environmental consequences reach far beyond its borders--China is second only to the United States in greenhouse gas emissions. Expanding its supply of other energy sources, like nuclear power and imported oil, raises trade and security issues. Soaring electricity demand necessitates the construction of 40-70 GW of new capacity per year, creating sustained financing challenges. While daunting, the challenge of meeting China's energy needs presents a wealth of opportunities, particularly in meeting demand through improved energy efficiency and other clean energy technologies. The China Energy Group at the Lawrence Berkeley National Laboratory (LBNL) is committed to understanding these opportunities, and to exploring their implications for policy and business. We work collaboratively with energy researchers, suppliers, regulators, and consumers in China and elsewhere to: better understand the dynamics of energy use in China. Our Research Focus Encompasses Three Major Areas: Buildings, Industry, and Cross-Cutting Activities. Buildings--working to promote energy-efficient buildings and energy-efficient equipment used in buildings. Current work includes promoting the design and use of minimum energy efficiency standards and energy labeling for appliances, and assisting in the development and implementation of building codes for energy-efficient residential and commercial/public buildings. Past work has included a China Residential Energy Consumption Survey and a study of the health impacts of rural household energy use. Industry--understanding China's industrial sector, responsible for the majority of energy consumption in China. Current work includes benchmarking China's major energy-consuming industries to world best practice, examining energy efficiency trends in China's steel and cement industries, implementing voluntary energy efficiency agreements in various

  13. Analyses of energy supply options and security of energy supply in the Baltic States

    International Nuclear Information System (INIS)

    2007-02-01

    In its broadest meaning 'energy security' is the ability of a nation to muster the energy resources needed to ensure its welfare. In a narrower meaning it refers to territorial energy autonomy. Consequently, energy supply security is a matter of both domestic policy and international relations. Perceived and real threats may be economic or logistic, politically motivated or the result of war or natural causes. They may be source, technology or transport related, specific to a facility or a function of system structure, due to sabotage or to inadequate investment or maintenance, or result from pricing or regulatory policies. Energy security has become a growing concern in the Baltic States of Estonia, Latvia and Lithuania since regaining independence in 1991. As their national energy systems depend on essentially one single foreign supplier for most of their oil and all of their natural gas supplies, a comprehensive analysis of potential measures to improve security including alternative supply options becomes vital. Such an analysis needs to consider, for example, the availability of domestic energy reserves and resources, the vintage of existing energy infrastructures (including regional and interregional interconnections), storage facilities, as well as future technology and energy trade options. However, the Baltic States' accession to the European Union in 2004 has added further responsibilities with regard to energy security. Robust future energy development strategies, for each individual country and the region as a whole, will also require compliance with EU regulations, as well as with special stipulations formulated in the accession agreements. Robust energy strategies need to strike a balance between the potentially conflicting dimensions of energy security, economic efficiency and environmental protection. For example, supply security is likely to incur an 'insurance premium', while environmental protection may well raise the cost of providing energy

  17. Role of biomass in global energy supply

    International Nuclear Information System (INIS)

    Best, G.; Christensen, R.; Christensen, J.

    2003-01-01

    Bioenergy is energy of biological and renewable origin, normally in the form of purpose-grown energy crops or by-products from agriculture, forestry or fisheries. Biomass provides approximately 11-14% of the world's energy, but there are significant differences between industrialised and developing countries. In many developing countries biomass is the most important energy source. As a global average, biomass provides approximately 35% of developing countries' energy, but there are large regional differences. Many sub-Saharan African countries depend on biomass for up to 90% of their energy indicating that they have little in the way of industry or other modern activities. In the last decade interest in bioenergy has increased in industrialised countries partly due to growing concern about climate change, technological advances in biomass conversion, increasing focus on security of energy supply, and increasing interest in renewable energy generally. Two trends emerge: The developing countries will in general aim to reduce their dependence on traditional bioenergy. The relative share of bioenergy in the energy balance will therefore go down, though the number of people depending on traditional bioenergy probably will remain constant, with corresponding consequences for health and resources. Industrialised countries, plus a number of developing countries, will aim to increase their use of modern bioenergy technologies. With the traditional association of bioenergy as old fashioned and for the poor, the recent interest in biomass resources has invented a new term 'modern bioenergy' which covers a number of technological areas from combustion at domestic, industrial or power plant scale, gasification, hydrolysis, pyrolysis, extraction, digestion etc. There are some barriers to the increased use of bioenergy, but they can be overcome through dedicated interventions by public and private sector entities.

The serious situation and challenges concerning the national energy security and energy sustainable development, and major tasks proposed to carry out the strategy of energy sustainable development are expounded in the first part. In the second part, the position and role of nuclear energy in China are elaborated and analyzed in detail. Firstly, it is indicated that the development of nuclear energy is the objective requirement for optimizing national energy structure. From the viewpoint of climate and environment protection, energy mix is required to transit from conventional fossil fuels to clean and high-quality energy sources. The potential role of nuclear energy in energy structure optimization in China is compared with that of hydro and other renewable energy sources. Secondly, it is proposed that the development of nuclear energy is the important security option for safely supplying the national energy and electricity in the future, mainly from the point of nuclear power providing stable and reliable power supply, relieving the burden of coal exploitation and transportation and reducing the risk of energy security caused by dependence on oil and natural gas. Thirdly, it is elaborated that the development of nuclear energy is the inevitable selection for carrying out the national energy and electricity sustainable development. It is given further details that nuclear energy is a clean and economical energy option, a preference coinciding with the principles of the circular economy, a feasible technical choice to greatly reduce emission of greenhouse gases, a selection contributing to

    Full Text Available Food companies are increasingly challenged to balance business performance and economic gains with environmental and social performance. Therefore, in 2012, we started a collaborative project on this topic named SCALE (Step Change in Agri-food Logistics Ecosystems. SCALE aims to improve the sustainability of food and drink supply chain logistics in the context of rising food demands, increasing energy prices and the need to reduce environmentally damaging emissions. More in particular, SCALE aims to deliver a number of tools and frameworks valuable for the agri-food sector to secure a step change in operational practices, which will improve the efficiency and sustainability of supply chain logistics. In the paper we present the first results of this project. Aim of this paper is (1 to present a sustainability research framework for food supply chains logistics including drivers, strategies, performance indicators, metrics and improvement opportunities to measure and potentially enhance sustainability performances; and (2 to analyse and diagnose the current status of Dutch food & drinks companies and logistics service providers using this framework. Results are found via a literature review, web-based research and structured interviews with Dutch food and logistics service industry.

    Full Text Available The purpose of this research is to explore sustainable supply chain management (SSCM trends, and firms’ strategic positioning and execution with regard to sustainability in the textile and apparel industry based on news articles and sustainability reports. Further analysis of the rhetoric in Chief executive officer (CEO letters within sustainability reports is used to determine firms’ resoluteness, positive entailments, sharing of values, perception of reality, and sustainability strategy and execution feasibility. Computer-based content analysis is used for this research: Leximancer is applied for text analysis, while dictionary-based text mining program DICTION and SPSS are used for rhetorical analysis. Overall, contents similar to the literature on environmental, social, and economic aspects of the triple bottom line (TBL are observed, however, topics such as regulation, green incentives, and international standards are not readily observed. Furthmore, ethical issues, sustainable production, quality, and customer roles are emphasized in texts analyzed. The CEO letter analysis indicates that listed firms show relatively low realism and high commonality, while North American firms exhibit relatively high commonality, and Europe firms show relatively high realism. The results will serve as a baseline for providing academia guidelines in SSCM research, and provide an opportunity for businesses to complement their sustainability strategies and executions.

    Full Text Available Researchers and practitioners are taking more interest in developing sustainable garment supply chains in recent times. On the other hand, the supply chain manager drops sustainability objectives while coping with unexpected natural and man-made disruption risks. Hence, supply chain managers are now trying to develop sustainable supply chains that are simultaneously resilient enough to cope with disruption risks. Owing to the importance of the considered issue, this study proposed a network optimization model for a sustainable and resilient supply chain network by considering sustainability via embodied carbon footprints and carbon emissions and resilience by considering resilience index. In this paper, initially, a possibilistic fuzzy multi-objective sustainable and resilient supply chain network model is developed for the garment industry considering economic, sustainable, and resilience objectives. Secondly, a possibilistic fuzzy linguistic weight-based interactive solution method is proposed. Finally, a numerical case example is presented to show the applicability of the proposed model and solution methodology.

    Energy scenarios provide a framework for exploring future energy perspectives, including various combinations of technology options and their implications. Many scenarios in the literature illustrate how energy system developments may affect global change. Examples are the new emissions scenarios by the Intergovernmental Panel on Climate Change (IPCC) and the energy scenarios by the World Energy Assessment (WEA). Some of these scenarios describe energy futures that are compatible with sustainable development goals; such as improved energy efficiencies and the adoption of advanced energy supply technologies. Sustainable development scenarios are also characterized by low environmental impacts (at local, regional and global scales) and equitable allocation of resources and wealth. They can help explore different transitions toward sustainable development paths and alternative energy perspectives in general. The considerable differences in expected total energy requirements among the scenarios reflect the varying approaches used to address the need for energy services in the future and demonstrate effects of different policy frameworks, changes in human behavior and investments in the future, as well as alternative unfolding of the main scenario driving forces such as demographic transitions, economic development and technological change. Increases in research, development and deployment efforts for new energy technologies are a prerequisite for achieving further social and economic development in the world. Significant technological advances will be required, as well as incremental improvements in conventional energy technologies. In general, significant policy and behavioral changes will be needed during the next few decades to achieve more sustainable development paths and mitigate climate change toward the end of the century.

    The complexity facing today's energy planners and decision-makers, particularly in electricity sector, has increased. They must take into account many elements in selecting technologies and strategies that will impact near term energy development and applications in their countries. While costs remain a key factor, tradeoffs between the demands of environmental protection and economic development will have to be made. This fact, together with the needs of many countries to define their energy and electricity programmes in a sustainable manner, has resulted in a growing interest in the application of improved data, tools and techniques for comparative assessment of different electricity generation options, particularly from an environmental and human health viewpoint. Although global emissions of greenhouse gases and other pollutants, e.g. SO 2 , NO x and particulate, must be reduced, the reality today is that these emissions are increasing and are expected to continue increasing. In examining the air pollutants, as well as water effluents and solid waste generated by electricity production, it is necessary to assess the full energy chain from fuel extraction to waste disposal, including the production of construction and auxiliary materials. The paper describes this concept and illustrates its implementation for assessing and comparing electricity generation costs, emissions, wastes and other environmental burdens from different energy sources.

    1991-01-01

    Europe and North America account for 70% of world energy consumption; 61% of which is fossil fuels. Energy trends and patterns in this region, if pursued, would have a large impact on region- and world-wide energy and ecosystems. This report addresses the issues of whether projected trends and supply structures would be 'sustainable' i.e. meet the needs of the present without compromising the ability of future generations to meet their own needs; what adaptations are warranted; and what role could and should be played by regional energy and environmental co-operation: including through the United Nations Economic Commission for Europe. The report is divided into three parts. Part 1 studies the interrelationships between environmental and energy policies in Europe and North America until 2010 and beyond. Part II contains research notes on CO{sub 2} concentration and energy scenarios; investment requirements of the energy supply industries in the ERE region for 1980-2000; energy technologies for the first decades of the 21st century. Scope and conditions for enhancing energy efficiency in the ERE region; CO{sub 2} and climate variation and its impact on energy policy in the USSR and European CMEA countries; the role of new and renewable sources of energy; projected energy developments in the ERE region until 2010, and pollution: synopsis of various international studies on the sustainability of energy developments. Part III describes the energy program of the UN-ECE.

    Geoethics consists of the researches and reflections on those values upon which are based the appropriate practices concerning human activities interesting Geosphere. Since Geoethics deals with ethical, social and cultural implications of geological research, it also reflects the opportunity for any researcher to become more conscious of the social role and responsibilities in conducting activities related to the environmental management and geo-resources exploitation. In this context Geoethics would also represent a concrete tool to sensitize and influence the awareness of society opening questions on the reliability and sustainability of the technological options presently proposed as a way to answer the huge global energy demand. Aim of this note is to generally discuss the role of geoscientists in the framework of the development of a sustainable energy supply chain related to georesources exploitation, in terms of making ethical choices during each phase of the process, from the research of potential sources of energy to their feasible and reliable exploitation. Since the beginning of energetic revolution, the well established energy supply chain technological models often force the research community to approach such system unconsciously accepting it, or conversely refusing it at all. We would point out that make geoethical choices for georesources supply purposes should not be to prejudicially counteract the whole supply system, but rather to base the research activity on a solid background scheme of perspectives, principles and criteria which could make the people aware of the improvements and drawbacks of their work. This basically means to avoid the overexploitation of non-renewable resources, to fairly develop more efficient technological and green procedures abating the local and/or the diffuse pollution, or consciously and carelessly expose vulnerable elements like humans and infrastructures to natural and artificial geological hazards.

    2017-01-01

    Full Text Available A systematic literature review of supply chain maturity models with sustainability concerns is presented. The objective is to give insights into methodological issues related to maturity models, namely the research objectives; the research methods used to develop, validate and test them; the scope; and the main characteristics associated with their design. The literature review was performed based on journal articles and conference papers from 2000 to 2015 using the SCOPUS, Emerald Insight, EBSCO and Web of Science databases. Most of the analysed papers have as main objective the development of maturity models and their validation. The case study is the methodology that is most widely used by researchers to develop and validate maturity models. From the sustainability perspective, the scope of the analysed maturity models is the Triple Bottom Line (TBL and environmental dimension, focusing on a specific process (eco-design and new product development and without a broad SC perspective. The dominant characteristics associated with the design of the maturity models are the maturity grids and a continuous representation. In addition, results do not allow identifying a trend for a specific number of maturity levels. The comprehensive review, analysis, and synthesis of the maturity model literature represent an important contribution to the organization of this research area, making possible to clarify some confusion that exists about concepts, approaches and components of maturity models in sustainability. Various aspects associated with the maturity models (i.e., research objectives, research methods, scope and characteristics of the design of models are explored to contribute to the evolution and significance of this multidimensional area.

    To sustain decent environmental conditions, it is essential to contain the emission of greenhouse gases. to a great extent, this can be achieved by reducing the almost exclusive dependence of fossil fuels for producing electricity and by championing nuclear energy and the renewable, which in the end are the least contaminating. Specifically, operation of the European nuclear fleet avoids the yearly emission of 700 million tons of CO 2 to the atmosphere. The need to combat climate change is very serious and increasingly imminent, especially if we remember that the World Health Organization has said that climate change could eventually cause 300,000 deaths. The different social players are aware of the problem. In fact, the European Union's Cabinet of Ministers approved the post-kyoto Environmental Strategy, which underlines the need to reduce CO e missions by 80% by the year 2050. It seems obvious that, in the long run, technological research and development will be fundamental pieces in the battle against environmental change and in the effort to one day provide 2,000 million people with access to electricity.

    Narula, Kapil; Reddy, B. Sudhakara

    2016-01-01

    Measuring the performance of the energy system of a country is a prerequisite for framing good energy polices. However, the existing indices which claim to measure energy security have limited applicability for developing countries. Energy sustainability is also increasingly gaining importance and countries are keen to measure it to tailor their energy policies. Therefore, the concept of SES (sustainable energy security) has been proposed as the goal for a developing country. This paper presents an analytical framework for the assessment of SES of an energy system and the methodology for constructing an SES index. A hierarchical structure has been proposed and the energy system has been divided into 'supply', 'conversion & distribution' and 'demand' sub-systems. Each subsystem is further divided into its components which are evaluated for four dimensions of SES, Availability, Affordability, Efficiency and (Environmental) Acceptability using quantitative metrics. Energy indices are constructed using 'scores' (objective values), and 'weights' (subjective values representing tradeoffs) which are then aggregated, bottom-up, to obtain an overall SES Index for a country. The proposed SES Index is multidimensional, quantitative, modular, systemic and flexible. Such a SES Index can be used to design policy interventions for transitioning to a sustainable and a secure energy future. - Highlights: • A SES (sustainable energy security) index is proposed for developing countries. • A hierarchical structure includes the entire energy system from supply to end use. • The performance of all energy sources, energy carriers and sectors is assessed. • Availability, affordability, efficiency and acceptability dimensions are evaluated. • The SES index is multidimensional, quantitative, modular, systemic and flexible.

    Problems with energy supply and use are related not only to global warming, but also to such environmental concerns as air pollution, ozone depletion forest destruction and emission of radioactive substances. These issues must be taken into consideration simultaneously if humanity is to achieve a bright energy future with minimal environmental impacts. Much evidence exists which suggests that the future will be negatively impacted if humans keep degrading the environment. There is an intimate connection between energy, the environment and sustainable development. A society seeking sustainable development ideally must utilise only energy resources which cause no environmental impact (e.g. which release no emissions to the environment). However, since all energy resources lead to some environmental impact, it is reasonable to suggest that some (not all) of the concerns regarding the limitations imposed on sustainable development by environmental emissions and their negative impacts can be part overcome through increased energy efficiency. A strong relation clearly exists between energy efficiency and environmental impact since, for the same services or products, less resource utilisation and pollution is normally associated with higher efficiency processes. Anticipated patterns of future energy use and consequent environmental impact (Focusing on acid precipitation, stratospheric ozone depletion and the greenhouse effect) are comprehensively discussed in this paper. Also, some solutions to current environmental issues in terms of energy conservation and renewable energy technologies are identified and some theoretical and practical limitations on increased energy efficiency are explained. The relations between energy and sustainable development, and between the environment and sustainable development, are described, and in illustrative example is presented. Throughout the paper several issues relating to energy, environment and sustainable development are examined

    1983-02-01

    The author describes the Point Lepreau nuclear power plant and its impact on the electric power grid and the economy of the small province of New Brunswick. The 600 MW CANDU reactor is considered suitable for small operations and has an excellent world record. Although nuclear energy has high capital costs, its fuel costs are low, thus rendering it comparatively inflation free. Its fuel costs of 3 to 4 mills are contrasted with 40 mills for oil-fuelled units. The cost advantage of uranium over coal and oil permits New Brunswick to put aside funds for waste management and decommissioning. Regulatory streamlining is needed to reduce both expense and time of construction. The CANDU system is ideally suited to providing base load, with coal as an intermediate load supply and hydro for peaking. There is room for tidal power as a future part of the mix

    2000-01-01

    A project on 'Indicators for Sustainable Energy Development (ISED)' was introduced by the IAEA as a part of its work programme on Comparative Assessment of Energy Sources for the biennium 1999-2000. It is being pursued by the Planning and Economic Studies Section of the Department of Nuclear Energy. The envisaged tasks are to: (1) identify the main components of sustainable energy development and derive a consistent set of appropriate indicators, keeping in view the indicators for Agenda 21, (2) establish relationship of ISED with those of the Agenda 21, and (3) review the Agency's databases and tools to determine the modifications required to apply the ISED. The first two tasks are being pursued with the help of experts from various international organizations and Member States. In this connection two expert group meetings were held, one in May 1999 and the other in November 1999. The following nine topics were identified as the key issues: social development; economic development; environmental congeniality and waste management; resource depletion; adequate provision of energy and disparities; energy efficiency; energy security; energy supply options; and energy pricing. A new conceptual framework model specifically tuned to the energy sector was developed, drawing upon work by other organizations in the environmental area. Within the framework of this conceptual model, two provisional lists of ISED - a full list and a core list - have been prepared. They cover indicators for the following energy related themes and sub-themes under the economic, social and environmental dimensions of sustainable energy development: Economic dimension: Economic activity levels; End-use energy intensities of selected sectors and different manufacturing industries; energy supply efficiency; energy security; and energy pricing. Social dimension: Energy accessibility and disparities. Environmental dimension: Air pollution (urban air quality; global climate change concern); water

    2012-01-01

    Highlights: ► European excess heat recovery and utilisation by district heat distribution. ► Heat recovery in district heating systems – a structural energy efficiency measure. ► Introduction of new theoretical concepts to express excess heat recovery. ► Fourfold potential for excess heat utilisation in EU27 compared to current levels. ► Large scale excess heat recovery – a collaborative challenge for future Europe. -- Abstract: Increased recovery of excess heat from thermal power generation and industrial processes has great potential to reduce primary energy demands in EU27. In this study, current excess heat utilisation levels by means of district heat distribution are assessed and expressed by concepts such as recovery efficiency, heat recovery rate, and heat utilisation rate. For two chosen excess heat activities, current average EU27 heat recovery levels are compared to currently best Member State practices, whereby future potentials of European excess heat recovery and utilisation are estimated. The principle of sequential energy supply is elaborated to capture the conceptual idea of excess heat recovery in district heating systems as a structural and organisational energy efficiency measure. The general conditions discussed concerning expansion of heat recovery into district heating systems include infrastructure investments in district heating networks, collaboration agreements, maintained value chains, policy support, world market energy prices, allocation of synergy benefits, and local initiatives. The main conclusion from this study is that a future fourfold increase of current EU27 excess heat utilisation by means of district heat distribution to residential and service sectors is conceived as plausible if applying best Member State practice. This estimation is higher than the threefold increase with respect to direct feasible distribution costs estimated by the same authors in a previous study. Hence, no direct barriers appear with

    This invention aims to solve the problems of stable supply of natural energy and the construction cost, enhancing the power output per unit area, producing a hydrogen gas which is free from pollution, thus stably supplying power and hydrogen fuel. In this invention, integration is made of the systems such as a light/heat collection system wherein the solar light is collected and converted into heat, a thermal power generating system which converts the heat into electricity, a wind power generating system wherein a wind receiving blade is rotated by the wind power and the rotation force is converted into electricity and a wave power generating system which converts the tidal force into electricity and a current power generating system. By this arrangement, the take out of electric energy per unit area was increased. In addition, hydrogen is produced by an electrolysis of water by utilizing this electric power. 3 figs.

    In September 2012 after nationwide discussions, Energy and Environmental Council decided 'Innovative Strategy for Energy and the Environment': (1) Realization of a society not dependent on nuclear power, (2) Realization of green energy revolution, (3) For ensuring stable supply of energy, (4) Bold implementation of reform of electricity power systems and (5) Steady implementation of global warming countermeasures. Energy problem should be considered as supply and demand of whole energy. However, long-term energy problem such as in 2050 should assume global limits of fossil fuel supply and carbon dioxide emission and then in order to realize sustainable demand and supply of energy, maximum deployment of renewable energy power in primary energy and most practicable electrification of final demand for energy conservation should be implemented. Best mix of power and energy demand and supply would be significant to some extent. This article outlined analysis of power demand and supply in a long term, future power technologies and demand side management, and problems of power system operation and their solution, and then described energy system integration to realize power and energy/society best mix.

    2005-01-01

    In embarking on a dynamic course of economic development and industrial modernism, Malaysia sees the need to increase its electricity generation capacity through the development of a mega-dam project - the Bakun dam. Although hydroelectricity generation offers one of the benign options in accommodating the increasing energy consumption per capita in Malaysia, it is argued that the construction of Bakun's dam which involves a complete and irreversible destruction of 69,640 ha of old forest ecosystem remains a difficult and uncertain endeavour. It is further argued that apart from mega-dam technology, there are also other means to orchestrate a sustainable energy system in Malaysia. These include the implementation of demand and supply initiatives, such as the deployment of energy saving technology or influencing behavioral change towards a sustainable energy consumption pattern

    The authors analyze the Mexican energy policy taking as reference the methodological framework for sustainable energy development proposed by the Economic Commission for Latin America and the Caribbean. This methodology takes eight related indicators to the social, environmental and economic dimensions in order to calculate a general sustainability indicator for the energy sector. In this methodology, the weight of each dimension is different; namely, the social and environmental issues have less relevance than the economic issues. The authors use this methodology because government institutions as the Department of Energy and the Department of Environment and Natural Resources have used some indicators from such a methodology to propose plans, programs, projects and bills. Authors know of the existence of other methodologies about sustainability. Nonetheless, opting for the Economic Commission for Latin America and the Caribbean's methodology is convenient because this organization is a respectable authority for civil servants from the Mexican institutions. Our objective is just to contrast the sustainability grade of the energy sector between 1990 and 2008 for Mexico whose government started reforms in the 1990s. It concludes that those reforms did not bring about a higher sustainability level for the energy sector. - Highlights: ► We used the OLADE, CEPAL and GTZ's methodology to calculate sustainability indicators for the Mexican energy sector. ► We studied the Mexican energy policy from 1990 to date and presented it. ► Currently, the Mexican energy sector is less sustainable than in 1990.

    Besides technical, political and economic aspects of energy sustainability there are several social, behavioural and psychological dimensions of vital importance for a successful implementation of Renewable Energy Systems (RES) and Rational Use of Energy (RUE) within communities. The European Project ''Sustainable Communities-on the energy dimension'' pursues an interdisciplinary approach to detect essential success and facilitating factors. In the last years social and psychological aspects in the process of sustainability came to the fore more and more. Not only as a complementary science to facilitate the technical aims in the change process but also as an essential part for success. (authors)

    During the particle-acceleration period, the magnet guide-field intensity, along the equilibrium orbit must rise from a minimum field (corresponding to injection energy) to the peak field, at which the protons attain their maximum energy. The field must then be reduced to its minimum value and the cycle repeated. This operation is achieved by excitation of the guide-field magnets with a 10 Hz sinusoidal waveform, which is biased by superimposing a dc component on the ac component excitation, giving a field variation of the form: b(t) = B dc - B ac sin (2π ft) where f is the magnet excitation frequency (nominally 10 Hz). Aside from saturation effects in the magnets and chokes, b(t) may be considered as a linear function of the magnet current (design of network magnetic elements should not allow more than 1% saturation, i.e., peak field should not exceed 1.25 T). With this assumption, the magnet power supply generates a current of the form (Figure 1) i m (t) = I dc - I ac sin (2π ft). 7 figs., 3 tabs

    The VROM Council offered to host a workshop (27-28 October 2000) for a group of European environmental advisory bodies. This meeting is meant as a kick-off for a working group on energy and climate change. The workshop may help to develop standpoints of the advisory bodies on the basis of shared knowledge of problem perceptions and proposed solutions in other EU countries. This may increase the common denominator and thus promote common EU policies. The proposed title for this workshop is: Reconciling a sustainable energy future with the liberalisation and privatisation of the European energy market One of the participating councils from each country is expected to draft a report on the policies directed at a sustainable energy future in their respective countries. These reports should include the following elements of the national policies and relevant proposals of the councils: a brief description of the current energy supply and a lookout on sustainable development in the energy sector; .a description of the liberalisation and privatisation of the energy market, including the institutional reform (government involvement), juridical changes and realisation path and, if applicable, how the share of non fossil energy generation is enlarged; a description of how in the future a sustainable energy supply will be promoted, including (options for) policy strategies, measures and instruments; and a description of the European Union (EU) policy that is conditional for the realisation of these national policies. The VROM Council has asked CE to produce the report for the Netherlands. The report is organised as follows. Chapter 2 gives a brief description of the current Dutch energy and CO2 characteristics. Chapter 3 gives an overview of Dutch energy policy and chapter 4 an overview of Dutch climate policy. The chapters 5-7 give the views of the various councils on energy and climate policy (AER, VROMRaad, and SER). The final chapter, chapter 8, gives some suggestions for

    For over 50 years now, the global primary energy demand structure has been based on fossil fuels for more than 80%. In 25 years, our energy needs will still be covered by an over 80% fossil energy mix according to the reference scenario of most energy agencies. Over this period of time, the economics of energy will be radically altered as a result of a long term sustained global demand of energy and a growing constraint on some hydrocarbon production, conventional oil in particular. The oil production profile on currently operated oil fields, essentially in the OECD, will further decline or require significantly increasing investments. Non conventional oil sources are already proving to be even more capital-intensive. In the face of dwindling reserves in the old OECD hydrocarbon basins, the only resource-rich region in the world with low extraction costs and available swing supply capacities is the Middle East. Tomorrow's oil industry and markets will therefore represent a risk concentrated around a single region in the world, whilst the global gas industry will face a risk concentrated around two regions in the world, including Russia and the Middle East. Massive investments in energy infrastructures will be necessary to bring gas from these two sources to the remote markets in Asia, Europe or the US. The era of cheap energy is definitely gone. Far from being an obsolete fuel, coal is and will remain the most abundant, competitive and favoured source of energy for power generation across the world. CO 2 emissions from coal use are coal's only handicap. The vision of our energy future is in front of us: the environment will be filthy, energy will be costly and geopolitical tensions between producers and consumers will be strong

Production and cost data provided in this paper are based on an ongoing project (Artepal. Stability data are derived from a development project on rectal artesunate. Discussion The artemisinin raw material and its derivatives appear to be very stable compared to the finished products. Supply of artemisinin changed in May 2004 when the Global Fund shifted financial support to qualified countries from chloroquine or sulphadoxine-pyrimethamine to an ACT for treatment of malaria. First, there was a sudden shortage of the starting material, and short term scarcity led to a steep rise in API price: it increased dramatically in 2004, from $350 per kg to more than $1000. Second, there was a parallel increase in the number of companies extracting artemisinin from 10 to 80 between 2003 and 2005 in China, and from 3 to 20 in Vietnam. Commercial cultivation began also in East Africa and Madagascar. A steady and predictable demand for the crop can eliminate such wide fluctuations and indirectly contribute to price stability of the herb, the API and ACT. With appropriate mechanisms to reduce those fluctuations, the cost of artemisinin might decrease sustainably to US$ 250–300 per kg.

    2007-01-01

    In the course of the current discussion on promoting the economical competitiveness of sustainable energy systems, especially renewable and non-CO 2 -intensive ones, interest in nuclear energy has re-awakened in Europe (''nuclear renaissance''). This paper starts with presenting the concept of energy sustainability and its main elements. Next, an overview of the main results of sustainability assessments for different energy supply options (nuclear, fossil, renewables) covering full energy chains is given. Nuclear energy's typical strong and weak points are identified from a sustainability point of view. On the basis of these results, it is argued that more emphasis on nuclear energy's (very good) total cost performance, i.e. incl. externalities, rather than on its (very good) contribution to combating climate change would stronger benefit its ''renaissance''. Finally, the development of an overall EU-wide framework is proposed in order to assess the sustainability performance of alternative energy supply options, incl. nuclear, across their lifecycle and thus support decision making on developing sustainable energy mixes.

    The status and role of nuclear energy in the energy security and sustainable energy development strategy in China are discussed. Specifically, the role of nuclear energy in meeting the requirements of energy and electricity supply, environment protection and greenhouse gas (GHG) emission-reduction is focused on. The report is mainly composed of three component parts. The serious situation and challenges concerning the national energy security and energy sustainable development are expounded. It is indicated that the development of nuclear energy is the objective requirement for optimizing national energy structure. It is proposed that the development of nuclear energy is the important security option for safely supplying the national energy and electricity in the future. It is elaborated that the development of nuclear energy is the inevitable selection for carrying out the national energy and electricity sustainable development. Nuclear energy is a preference coinciding with the principles of the circular economy, a selection contributing to improvement of ecological environment and an inexhaustible resource in the long term. Some suggestions are put forward to the nuclear energy development in China. (authors)

    Germany, like other states, committed itself to sustainable development in the Rio declaration of 1992. The boundary conditions for this are set by nature itself, whose laws must be respected if goals like reliability of supply and economic efficiency are to be achieved. This study of the Federal Environmental Office shows how sustainable power supply can be achieved. It is possible to combine climate protection, reliability of supply and economic efficiency, even without nuclear power and without constructing new conventional power plants that do not have the function of combined heat and power generation.

  20. Mining and sustainable development: Considerations for minerals supply

    International Nuclear Information System (INIS)

    Lambert, Ian B.

    2001-01-01

    Sustainable development involves meeting the needs of human societies while maintaining viable biological and physical Earth systems. The needs include minerals: metals, fuels, industrial and construction materials. There will continue to be considerable demand for virgin mineral resources, even if levels of recycling and efficiency of use are optimal, and rates of population growth and globalisation decrease significantly. This article aims to stimulate debate on strategic issues for minerals supply. While the world has considerable stocks of mineral resources overall, international considerations of the environmental and social aspects of sustainable development are beginning to result in limitations on where mining will be conducted and what types of deposits will be mined. Current and emerging trends favour large mines in parts of the world where mining can be conducted within acceptable limits of environmental and social impact. Finding new deposits that meet such criteria will be all the more challenging given a disturbing global decline in the rate of discovery of major economic resources over the last decade, and the decreasing land area available for exploration and mining. To attract responsible exploration and mining, governments and mining nations will need to provide: regional-scale geo-scientific datasets as required to attract and guide future generations of exploration; resource access through multiple and sequential land use regimes, and frameworks for dealing with indigenous peoples' issues; and arrangements for consideration of mining proposals and regulation of mines that ensure responsible management of environmental and social issues. The minerals industry will need to continue to pursue advances in technologies for exploration, mining, processing, waste management and rehabilitation, and in public reporting of environmental and social performance.

    2011-05-01

    The complexity of sustainable energy systems for buildings services calls for more transparency of the processes which provide energy for the buildings heating, cooling and power needs. In the frame of applied scientific research at University of Applied Sciences Offenburg, different systems and even buildings in total have been monitored over years to analyse their performance and to optimize the system installations and operations. New EU regulations like EN 16001 require an effective monitoring and a continuous commissioning of the energy relevant systems to certificate sustainable processes. On the other hand, new operation tools are necessary to handle the volatility of renewable energy sources and the buildings demand. Predictive building automation has shown good results when applied for energy systems with high inertia. Operating large-scale solar thermal systems and sustainable buildings over long-term periods the University of Applied Sciences provided evidence that monitoring is an essential system tool for an energy and cost efficient operation of sustainable buildings.

  2. Growth curves and sustained commissioning modelling of renewable energy: Investigating resource constraints for wind energy

    2014-01-01

    Several recent studies have proposed fast transitions to energy systems based on renewable energy technology. Many of them dismiss potential physical constraints and issues with natural resource supply, and do not consider the growth rates of the individual technologies needed or how the energy systems are to be sustained over longer time frames. A case study is presented modelling potential growth rates of the wind energy required to reach installed capacities proposed in other studies, taking into account the expected service life of wind turbines. A sustained commissioning model is proposed as a theoretical foundation for analysing reasonable growth patterns for technologies that can be sustained in the future. The annual installation and related resource requirements to reach proposed wind capacity are quantified and it is concluded that these factors should be considered when assessing the feasibility, and even the sustainability, of fast energy transitions. Even a sustained commissioning scenario would require significant resource flows, for the transition as well as for sustaining the system, indefinitely. Recent studies that claim there are no potential natural resource barriers or other physical constraints to fast transitions to renewable energy appear inadequate in ruling out these concerns. - Highlights: • Growth rates and service life is important when evaluating energy transitions. • A sustained commissioning model is suggested for analysing renewable energy. • Natural resource requirements for renewable energy are connected to growth rates. • Arguments by recent studies ruling out physical constraints appear inadequate

    This paper describes recent developments in a small nuclear heat and electricity production system - the SLOWPOKE Energy System - that make it possible to locate the system close to the load, and that could have a major impact on local energy supply. The most important unique features arising from these developments are walk-away safety and the ability to operate in an unattended mode. Walk-away safety means that radiological protection is provided by intrinsic characteristics and does not depend on either engineered safety systems or operator intervention. This, in our view, is essential to public acceptance. The capability for unattended operation results from self-regulation; however, the performance can be remotely monitored. The SLOWPOKE Energy System consists of a water-filled pool, operating at atmospheric pressure, which cools and moderates a beryllium-reflected thermal reactor that is fuelled with 100 to 400 kg of low-enriched uranium. The pool water also provides shielding from radioactive materials trapped in the fuel. Heat is drawn from the pool and transferred either to a building hot-water distribution system or to an organic liquid which is converted to vapour to drive a turbine-generator unit. Heating loads between 2 qnd 10 MWt, and electrical loads up to 1 MWe can be satisfied. SLOWPOKE is a dramatic departure from conventional nuclear power reactors. Its nuclear heat source is intrinsically simple, having only one moving part: a solid neutron absorber which is slowly withdrawn from the reactor to balance the fuel burnup. Its power is self-regulated and excessive heat production cannot occur, even for the most severe combinations of system failure. Cooling of the fuel is assured by natural physical processes that do not depend on mechanical components such as pumps. These intrinsic characteristics assure public safety and ultra high reliability

    Full Text Available In recent years, the interdisciplinary research of supply chains and sustainability has received extensive, yet gradual, attention; when compared to the rapid economic growth of the service industry, however, sustainable supply chain management has not been systematically explored yet. It has not only great theoretical significance, but also positive practical significance to provide a framework for the operation of a sustainable service supply chain from a sustainable development point of view. Based on the triple bottom line (TBL, we have analyzed related sustainable supply chain management research between 2006 and 2015, reviewed papers involving two or three bottom lines as well, and then introduced some classical frameworks for manufacturing supply chain management and service supply chain management. Afterward, by analyzing the differences between the manufacturing and service industries, we propose a framework of sustainable service supply chain management (SSSCM. Based on the impacts of sustainable development TBL on service supply chain participants, we have finally made a framework for sustainable operation facing triads service supply chain and proposed a future research agenda.

    Full Text Available Global business organizations face the challenges of adapting proper sustainability strategies and practices to effectively respond to social, ethical, environmental, and governance issues while improving financial performance in creating value for their shareholders. Business sustainability enables the integration of financial economic sustainability performance and non-financial environmental, social, ethical, and governance sustainability performance dimensions into the corporate culture, supply chain management and business models in creating shared value for all stakeholders. Business literature has provided mixed evidence of the tension, and possible link, between financial and non-financial sustainability performance dimensions and sustainability theories have yet to sufficiently address this tension. This paper attempts to fill this void by shedding light on the link between various dimensions of sustainability performance, their integrated effect on creating shared value for all stakeholders and their implications for supply chain sustainability. This paper examines the synergy between business sustainability and supply chain management by presenting a framework consisting of sustainability theories, sustainability performance dimensions, sustainability shared value concept, and sustainability best practices. Companies can use the suggested framework in integrating both financial and non-financial sustainability initiatives into their supply chain sustainability from production design, purchasing and inbound logistics, and manufacturing process to distribution and outbound logistics.

    Concerns over energy resource availability, energy security and climate change suggest an important role for nuclear power in supplying sustainable energy in the 21st century. The International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) was initiated in 2000 by a resolution of the IAEA General Conference to help ensure that nuclear energy is available to contribute to meeting global energy needs of the 21st century in a sustainable manner. It is a mechanism for IAEA Member States that have joined the project as INPRO members to collaborate on topics of joint interest. By 2010, INPRO membership had grown to 30 countries and the European Commission. The results of INPRO's activities, however, are made available to all IAEA Member States

The members of the supply chain in each stage need to invest in sustainable green technology innovation research and development. However, whether the sustainable green technology innovation investments and profits for all the members are fairness concerned is a critical factor to motivate the supply chain members. Motivated by a real business investigation, in this study, a supply chain model with one supplier and one manufacturer is analyzed. We consider fairness concerns for the supplier and the manufacturer with sustainable green technology innovation development. We derive the optimal results in both with and without fairness concern. The results indicate that fairness concerns can promote and coordinate the supply chain members without advantage inequity averseness, to invest more on their sustainable green technology innovation development.

    2018-02-01

    Full Text Available The comprehensive coverage of sustainability issues in a supply chain incurs goal conflicts—i.e., sustainability tensions—and is often limited by market characteristics, such as the availability of sustainable materials and services. While the mainstream business is prioritizing economic goals, a number of entrepreneurs are trying to move forward to more sustainable business practices for their own company and their supply chain. Fairphone represents such a case in the electronics industry, which is openly communicating its sustainability efforts and shortcomings. This communication is content-analyzed in this study by applying the theoretical lenses of paradox sustainability tensions and sustainable supply chain management. Findings of this analysis reveal the limitation of sustainability efforts by supply side characteristics, while Fairphone is innovatively using the demand side of its supply chain to drive sustainability. The resulting tensions among both sides are addressed via pro-active and direct supplier and stakeholder engagement by Fairphone at their suppliers’ mines and factories. The systematic identification of tensions and practices by which they are addressed is adding to our understanding of sustainability practices and goal conflicts in supply chains.

    China's energy supply security has faced many challenges such as the drastic change of the international energy environment and the domestic energy situation and so on. This paper constructs a multi-dimensional indicator system for the main risks deriving from four aspects to evaluate the situation of China's energy supply security and analyze its evolution characteristics from 1994 to 2011. The results indicate that the situation of China's energy supply security generally presented a downtrend during 1994–2008, as a result of increasing international energy market monopoly and high volatility of international crude oil prices. After 2008, the overall level of China's energy supply security has improved to the level of 2003, which is attributed to the relatively stable international energy environment as well as the effective implementation of energy policies. - Highlights: • A multi-dimensional index system for energy supply security is constructed. • The dynamic influences of external and internal risks are analyzed. • China's energy supply security presents a downward trend during 1994–2008. • The level of China's energy supply security has improved since 2009

    The consumption of natural aggregates in civil engineering applications can cause severe environmental impacts on a regional scale, depleting the stock of bulk resources within a territory. Several methods can improve the environmental sustainability of the whole aggregates' supply process, including natural and recycled aggregates' productive chains, for instance promoting the use of recycled aggregates (RA). However, when quarrying and recycling activities are considered as stand-alone processes, also the RA supply chain may not be as sustainable as expected, due to the high environmental loads associated to transportation, if high distances from the production to the use sites are involved. This work gives some insights on the environmental impact assessment of the aggregates' industry in the Italian context, through a comparative assessment of the environmental loads of natural and recycled aggregates' productive chains. An integrated plant for the extraction of virgin aggregates and recycling of construction and demolition waste (C&DW) was analyzed as significant case study, with the aim to identify the influence of sustainable solutions on the overall emissions of the facility. A Life Cycle Assessment (LCA) approach was used, using site-specific data and paying particular attention on transportation-related impacts, land use, avoided landfill and non-renewable resources preservation. From this work it was possible to evaluate the influence of transportation and PV energy use on the overall environmental emissions of natural and recycled aggregates' productive chains.

    The present revision of the PEN consists of two parts, a diagnosis and a strategy. In the diagnosis; the evolution and the changes are analyzed foreseen in the international and national environments to establish the form like the energy sector is affected and it responds to these conditions. In second part it revises the strategy to incorporate the required adjustments of agreement with the changes in the environment, the demand perspectives and sector and national politics limits. In the international thing, the process of transformation of the system economic World cup will contribute to strengthen the liberalization actions, deregulation and privatization of the economies of the development countries. Great part of the dynamics growth, will be sustained then in the private investment and in an atmosphere of global competition. The formation of regional blocks opens favorable perspectives for new cooperation forms and development of resources. In the case of the American hemisphere and with reference to the energy sector, one has an important potential to improve the self-sufficiency starting from regional supplies, especially starting from fossil resources. This expectation is important for Colombia that has well-known reservations and important potentials in these resources. The tendencies waited in the fossil resources are more favorable for the countries than they can have reservations and growing production of petroleum and of natural gas. Nevertheless, the development of the coal maintains favorable expectations, but with important requirements as for efficiency and quality in the production that it guarantee the positioning in a more and more concerned market. In the environmental thing, the growth foreseen in the consumption of fossil fuels also bears to the increment in the 2010 in the greenhouse gases, at levels between 36% and 49% superiors to those of 1990. That most of this increment will originate in the in the development countries and

    1999-01-01

    The twenty-first century will be an era in which sustainability will be a powerful value espoused by the community. The sustainability of energy, in terms of production and consumption, and in relation to the broader impacts of energy on society and the environment, will be a particular focus of the community. Australia, as a nett exporter of energy, and with a high per capita energy consumption, has both an economic and environmental imperative to be a leader in sustainable energy concepts and technologies. Australia therefore needs to position itself strategically, with a policy framework that facilitates the strategic positioning, to use and foster its diverse resources to provide for the social and economic needs of this generation, in a manner that ensures that the energy needs of the future generations can be met. The Institution of Engineers Australia has developed a Position on Sustainable Energy. The principles and actions through which the country's transition to a sustainable energy future will be managed are outlined

    Plas, Robert J. van der; Abdel-Hamid, Mahamat Ali

    2005-01-01

    Chad, like many other sub-Saharan African countries, depends for most of its energy demand on woodfuels; 90% or more of the country's energy balance comes from biomass energy. Obvious environmental problems appear around cities because of their highly concentrated demand, and this threatens the sustainability of supply. But, this does not need to be a problem, and woodfuel can also be an engine of economic growth, particularly in rural areas. A few policy conditions will need to be satisfied and in Chad this appears to be the case. As a result, the woodfuel supply of the capital N'Djamena could become sustainable, thereby continuing to provide low-cost energy to the urban population for the foreseeable future while giving income generation opportunities in rural areas. A win-win situation?!

    2018-02-01

    The environmental sustainability has emerged as a crucial aspect in the agri-food sector, nevertheless environmental assessments and certifications of cocoa and chocolate are still missing. Given this gap and the increasing global demand for cocoa derivatives, this study aims to evaluate the environmental impacts of an Italian dark chocolate through a holistic cradle-to-grave Life Cycle Assessment (LCA). The impact categories assessed are acidification potential (AC), eutrophication potential (EU), global warming potential (GW), photochemical ozone creation potential (POC), ozone layer depletion potential (OD), abiotic depletion (AD) and cumulative energy demand (CED). The obtained results highlight the relevant contributions of upstream phase (63% for the ODP, 92% for EU and 99% for the AD) and core processes (39% for the GW and 49% for the CED) on the overall impacts. Specifically, cocoa provisioning and energy supply at the manufacturing plant emerged as environmental hotspots and have been deeper investigated through a sensitivity analysis. Obtained outcomes show the significant variability of the environmental impacts due to the agricultural phase (i.e., depending on agroecosystems and practices) and environmental benefits guaranteed by an efficient trigeneration system implemented in the manufacturing plant. The quantification of the environmental impacts of chocolate through LCA, the identification of the main hotspots along the supply chain and the sensitivity analysis performed in this study could effectively support chocolate companies in their pathway towards environmentally sustainable productions.

    2016-09-15

    Our current dependency on the oil and gas (O&G) industry for economic development and social activities necessitates research into the sustainability of the industry's supply chains. At present, studies on sustainable supply chain management (SSCM) practices in the industry do not include firm-internal factors that affect the sustainability strategies employed by different functional areas of its supply chains. Our study aims to address this gap by identifying the relevant internal factors and exploring their relationship with SSCM strategies. Specifically, we discuss the commitment to and preparedness for sustainable practices of companies that operate in upstream and downstream O&G supply chain. We study the impact of these factors on their sustainability strategies of four key supply chain functions: supplier management, production management, product stewardship and logistics management. The analyses of data collected through a survey among 81 companies show that management preparedness may enhance sustainable supply chain strategies in the O&G industry more than commitment does. Among the preparedness measures, management of supply chain operational risks is found to be vital to the sustainability of all supply chain functions except for production management practices. The findings also highlight the central importance of supplier and logistics management to the achievement of sustainable O&G supply chains. Companies must also develop an organizational culture that encourages, for example, team collaboration and proactive behaviour to finding innovative sustainability solutions in order to translate commitment to sustainable practices into actions that can produce actual difference to their SSCM practices.

  16. Sustainable, Full-Scope Nuclear Fission Energy at Planetary Scale

    Directory of Open Access Journals (Sweden)

    Robert Petroski

    2012-11-01

    Full Text Available A nuclear fission-based energy system is described that is capable of supplying the energy needs of all of human civilization for a full range of human energy use scenarios, including both very high rates of energy use and strikingly-large amounts of total energy-utilized. To achieve such “planetary scale sustainability”, this nuclear energy system integrates three nascent technologies: uranium extraction from seawater, manifestly safe breeder reactors, and deep borehole disposal of nuclear waste. In addition to these technological components, it also possesses the sociopolitical quality of manifest safety, which involves engineering to a very high degree of safety in a straightforward manner, while concurrently making the safety characteristics of the resulting nuclear systems continually manifest to society as a whole. Near-term aspects of this nuclear system are outlined, and representative parameters given for a system of global scale capable of supplying energy to a planetary population of 10 billion people at a per capita level enjoyed by contemporary Americans, i.e., of a type which might be seen a half-century hence. In addition to being sustainable from a resource standpoint, the described nuclear system is also sustainable with respect to environmental and human health impacts, including those resulting from severe accidents.

  17. Nuclear energy for sustainable Hydrogen production

    2004-01-01

    There is general agreement that hydrogen as an universal energy carrier could play increasingly important role in energy future as part of a set of solutions to a variety of energy and environmental problems. Given its abundant nature, hydrogen has been an important raw material in the organic chemical industry. At recent years strong competition has emerged between nations as diverse as the U.S., Japan, Germany, China and Iceland in the race to commercialize hydrogen energy vehicles in the beginning of 21st Century. Any form of energy - fossil, renewable or nuclear - can be used to generate hydrogen. The hydrogen production by nuclear electricity is considered as a sustainable method. By our presentation we are trying to evaluate possibilities for sustainable hydrogen production by nuclear energy at near, medium and long term on EC strategic documents basis. The main EC documents enter water electrolysis by nuclear electricity as only sustainable technology for hydrogen production in early stage of hydrogen economy. In long term as sustainable method is considered the splitting of water by thermochemical technology using heat from high temperature reactors too. We consider that at medium stage of hydrogen economy it is possible to optimize the sustainable hydrogen production by high temperature and high pressure water electrolysis by using a nuclear-solar energy system.

    2010-01-01

    Energy is essential to the way we live. Whether it is in the form of oil, gasoline or electricity, a country's prosperity and welfare depends on having access to reliable and secure supplies of energy at affordable prices. However, it is also one of the benefits taken for granted by many people, knowing little about the impact of electricity on their lives. Having dependent mainly on oil and gas for half a century, Malaysia has started to realize the importance to adopt renewable energy in the energy mix and continuously reviewed its energy policy to ensure sustainable energy supply and security. This paper examines and discusses the intricacy of the existing and new energy policies, issues and challenges in Malaysia. The overall approach in addressing the energy issues and challenges will continue to focus on adequacy, quality, security and sustainability of both non-renewable and renewable energy supply in the country's development and the promotion and implementation of its energy efficiency programs. The recently launched National Green Technology Policy is also discussed. (author)

  20. Is nuclear fusion a sustainable energy form?

    International Nuclear Information System (INIS)

    Bradshaw, A.M.; Hamacher, T.; Fischer, U.

    2011-01-01

    An acceptable criterion for strong sustainability in the consumption of natural resources is an effective, or virtual, limitlessness of supply, which can be defined, albeit arbitrarily, as corresponding to a few million years. The fuels for nuclear fusion-lithium and deuterium-satisfy this condition because of the abundance of lithium in seawater and of deuterium in all forms of water. The possible use of lithium-ion batteries on a large scale, particularly in the automobile industry, could, however, use up all the known terrestrial reserves and resources of lithium in the next few decades. Little attention has been paid so far to the financial, energetic, and above all, environmental aspects of lithium extraction from seawater. The neutron multipliers foreseen for fusion power plants, in particular beryllium, represent a major supply problem and require that other, sustainable solutions be urgently sought.

    2013-01-01

    Energy is known as one of the essential ingredients for economic development and security of energy supply is crucial in ensuring continuous economic development of a country. Malaysia's proven domestic oil reserves are estimated to last for another 25 years, while that of gas for another 39 years as of 2011. Despite the depleting indigenous energy resources, the primary energy demand has continued to grow robustly, at an annual rate of 6.3 percent per year from 1990 to 2010, while the primary energy import has grown 7.2% per year and the primary energy export has grown at a slower rate of 1.9% per year. This worrying trend is further compounded by the faster rate of primary oil import averaging 10.5% per year while the primary energy export has shrink at a rate of 1.4% per year. This paper has identified two main concerns namely overdependence on fossil fuel and increasing energy import dependency in creating a precarious position towards energy self-sufficiency. The study will analyse the energy security of the country and explore possible options and challenges in enhancing the energy supply security toward sustainable environment.

    Provides an integrated perspective on understanding the impacts of climate change, energy and sustainable development on transportation infrastructure systems. Presents recent technological innovations and emerging concepts in the field of green and sustainable transportation infrastructure systems with a special focus on highway and airport pavements. Written by leading experts in the field. Climate change, energy production and consumption, and the need to improve the sustainability of all aspects of human activity are key inter-related issues for which solutions must be found and implemented quickly and efficiently. To be successfully implemented, solutions must recognize the rapidly changing socio-techno-political environment and multi-dimensional constraints presented by today's interconnected world. As part of this global effort, considerations of climate change impacts, energy demands, and incorporation of sustainability concepts have increasing importance in the design, construction, and maintenance of highway and airport pavement systems. To prepare the human capacity to develop and implement these solutions, many educators, policy-makers and practitioners have stressed the paramount importance of formally incorporating sustainability concepts in the civil engineering curriculum to educate and train future civil engineers well-equipped to address our current and future sustainability challenges. This book will prove a valuable resource in the hands of researchers, educators and future engineering leaders, most of whom will be working in multidisciplinary environments to address a host of next-generation sustainable transportation infrastructure challenges.

    Though hundreds of billions of dollars have been invested, past development efforts have been largely unable to break the cycle of poverty - a cycle that is directly linked to the provision of energy. Too often, the potential of local enterprises to provide essential energy services has been ignored. Yet such an enterprise is one of the most potent engines for shifting towards a local human capacity to produce and distribute modern energy services. This recognition lies at the heart of REED, an approach to developing new sustainable energy enterprises that use clean, efficient and renewable energy technologies to meet the energy needs of underserved populations.

    2011-01-01

    The long-term forecasting of energy supply and demand is an extremely important topic of fundamental research in Taiwan due to Taiwan's lack of natural resources, dependence on energy imports, and the nation's pursuit of sustainable development. In this article, we provide an overview of energy supply and demand in Taiwan, and a summary of the historical evolution and current status of its energy policies, as background to a description of the preparation and application of a Long-range Energy Alternatives Planning System (LEAP) model of Taiwan's energy sector. The Taiwan LEAP model is used to compare future energy demand and supply patterns, as well as greenhouse gas emissions, for several alternative scenarios of energy policy and energy sector evolution. Results of scenarios featuring 'business-as-usual' policies, aggressive energy-efficiency improvement policies, and on-schedule retirement of Taiwan's three existing nuclear plants are provided and compared, along with sensitivity cases exploring the impacts of lower economic growth assumptions. A concluding section provides an interpretation of the implications of model results for future energy and climate policies in Taiwan. - Research highlights: → The LEAP model is useful for international energy policy comparison. → Nuclear power plants have significant, positive impacts on CO 2 emission. → The most effective energy policy is to adopt demand-side management. → Reasonable energy pricing provides incentives for energy efficiency and conservation. → Financial crisis has less impact on energy demand than aggressive energy policy.

  13. Balancing the supply mix to meet tomorrow's energy needs

    This presentation emphasized the need to balance the power supply mix to ensure future energy needs. A balanced supply includes generation supply options that include renewable energy sources, natural gas, oil or coal. The role of combined heat and power (CHP) and district energy in this supply mix is considered to be a potential generation solution. The challenge facing Ontario's Independent Electricity Market Operator (IMO) is to balance supply and demand, phase out coal, promote renewables, diminish demand and determine the new role for natural gas. A graph by the National Energy Board depicting Canada's energy future and scenarios for supply and demand to 2025 indicates that gas yields from the Western Canada Sedimentary Basin are declining. It is expected that with growing demands for natural gas, prices will remain high and there will be a need for new generation capacity. The viable options for energy supply include a re-examination of the district energy advantage through industrial waste heat, biomass and other renewables, and the integration of industrial and community energy systems. Other options include the continued recognition of distributed generation in the form of combined heat and power. 4 figs

    An interim report on the long-range outlook of energy demands and supplies in Japan as prepared by an ad hoc committee, Advisory Committee for Energy was given for the period up to the year 2000. As the energy demands in terms of crude oil, the following figures are set: 460 million kl for 1990, 530 million kl for 1995, and 600 million kl for 2000. In Japan, without domestic energy resources, over 80% of the primary energy has been imported; the reliance on Middle East where political situation is unstable, for petroleum is very large. The following things are described. Background and policy; energy demands in industries, transports, and people's livelihood; energy supplies by coal, nuclear energy, petroleum, etc.; energy demand/supply outlook for 2000. (Mori, K.)

    Thirty-five years after the Agency's founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate -- but new energy-related concerns have arisen. Energy security is no longer only about oil. And the industrialised nations of the world are no longer the only major consumers of energy. Climate change driven by greenhouse gas emissions -- 60% of which derive from energy production or use -- is a growing threat. So energy policy was tasked with a new objective: to cut greenhouse gas emissions while maintaining economic growth.

    The wide use of nuclear energy has promoted the development of China's economy and the improvement of people's living standards. To some extent, the exploitation of nuclear power plants will solve the energy crisis faced with human society. Before the utilization of nuclear fusion energy, nuclear fission energy will be greatly needed for the purpose of alleviating energy crisis for a long period of time. Compared with fossil fuel, on the one hand, nuclear fission energy is more cost-efficient and cleaner, but on the other hand it will bring about many problems hard to deal with, such as the reprocessing and disposal of nuclear spent fuel, the contradiction between nuclear deficiency and nuclear development. This paper will illustrate the future and prospect of nuclear energy from the perspective of the difficulty of nuclear development, the present reprocessing way of spent fuel, and the measures taken to ensure the sustainable development of nuclear energy. By the means of data quoting and comparison, the feasibility of sustainable development of nuclear energy will be analyzed and the conclusion that as long as the nuclear fuel cycling system is established the sustainable development of nuclear energy could be a reality will be drawn.

    After briefly reviewing trends in energy demand, supply and efficiency, I will focus on the potential and outlook for the major low carbon energy sources - in order of decreasing current importance: bioenergy, hydro, nuclear, wind and solar. Together, they are sufficiently abundant to replace fossil fuels, which would presumably happen if they were economically competitive. I will discuss how close low carbon sources are to being competitive (which in the case of wind and solar depends on the cost of integrating large-scale intermittent supply), and the tech...

    After years of military conflict and economic turmoil, the countries of South East Europe now face major challenges in achieving the market reforms necessary to rebuild their economies. A major driver of economy is the energy sector, although high-energy intensities are a burden for the companies and households. An efficient energy sector not only is vital for an economic recovery but also plays an important role to energy transit. The main goal of this work is a comprehensive assessment of electrical sustainability in some countries of South East Europe (Romania, Bulgaria, Turkey and Greece) mainly by means of exergy analysis as well as descriptive statistics. Exergy analysis can be used as an energy sustainability indicator and help decision-makers. The concept of exergy, applied to electricity generation efficiency could be a useful tool in the field of energy efficiency. Further implementation of thorough exergy analysis to the countries of Eastern Balkans, would be helpful in improving their electricity generation efficiency

    This research proposes a dynamic assessment model for sustainable supply chain management in batik industry. The proposed model identifies the dynamic relationship between economic aspect, environment aspect and social aspect. The economic aspect refers to the supply chain operation reference model. The environment aspect uses carbon emissions and liquid waste as the attribute assessment, while the social aspect focus on employee’s welfare. Lean manufacturing concept was implemented as an alternative approach to sustainability. The simulation result shows that the average of sustainability score for 5 years increased from 65,3% to 70%. Future experiments will be conducted on design improvements to reach the company target on sustainability score.

    The Republic of Croatia has been building the Krsko Nuclear Power Plant and is participating in all the activities necessary for a successful operating of the plant now for almost thirty years. However, in the light of the nuclear energy renaissance it is necessary to prepare ourselves for new challenges, stricter criteria of safety and protection, respect the indispensability of continuous re-examination of safety of procedures and methods. The of Croatia has strictly committed herself to the nuclear energy programme development-CRONEP in accordance with the methodology of the International Atomic Energy Agency. Certainly, in the first moment till the possible decision on the building of nuclear power plant, it will be necessary to make an institutional framework and create human resources and such an infrastructure that will be able to, when the decision will be taken, support the project and realize it with maximal efficiency. We consider it the unique way in which it is possible to avoid what proved to be the weakness of some projects of nuclear power plants, that is missing a deadline and problems concerning financing that are intolerable taking into account the value of the investment. Likewise, since the Conference is dedicated to small and medium-sized electric networks or to small nuclear power programmes, it needs to be mentioned that except the largest facilities it should be promoted researching of nuclear power reactors of medium size whose development somehow falls behind in this moment Medium size reactors gives great advantages to smaller economies in technical and financial sense. From the current standpoint solutions of viability of nuclear programmes through re-processing of the spent nuclear fuel in new generation of power plants are discernible. Since today's technologies are sufficiently safe there is no need to wait with this development and fuel from one generation shall be re-processed into the fuel for the next generation of reactors.

    As the 20th century draws to a close, both individual countries and the world community face challenging problems related to the supply and use energy. These include local and regional environmental impacts, the prospect of global climate and sea level change associated with the greenhouse effect, and threats to international relations in connection with oil supply or nuclear proliferation. For developing countries, the financial cost of providing energy to provide basic needs and fuel economic development pose an additional burden. To assess the magnitude of future problems and the potential effectiveness of response strategies, it is important to understand how and why energy use has changed in the post and where it is heading. This requires study of the activities for which energy is used, and of how people and technology interact to provide the energy services that are desired. The authors and their colleagues have analyzed trends in energy use by sector for most of the world`s major energy-consuming countries. The approach we use considers three key elements in each sector: the level of activity, structural change, and energy intensity, which expresses the amount of energy used for various activities. At a disaggregated level, energy intensity is indicative of energy efficiency. But other factors besides technical efficiency also shape intensity.

    Full Text Available It has been widely discussed in Brazil that the production of biodiesel should look for ways for increasing competitiveness considering the balance among economic growth, environmental quality and social well-being through the rational use of resources. The main purpose of this paper is to identify structural dimensions influencing sustainability and competitiveness of the Brazilian biodiesel production chain and, thereby, contribute to the current debate as well as to the process of formulating policy and strategies regarding this important supply chain. As starting point, a number of publications were reviewed allowing the identification of main issues and its combination into relevant factors. Eventually, the factors were put together, resulting in a set of structural dimensions: biodiesel supply chain environment, institutional framework, market conditions, monitoring systems and technological innovation. Then, the structural dimensions were summarized in a conceptual model showing the relationship between them. The structural dimensions may be seen as critical points in which stakeholders would pay attention to ensure successful performance and sustainable competitiveness of the biodiesel production chain. The objective of the entire system is to deliver biodiesel as a clean energy with focus on social inclusion, mitigation of environmental impacts and viability.

    1998-01-01

    This article focuses on the main environmental problems caused by the development of the energy sector in Italy, addressing the current policies on energy production and consumption and the viable alternatives for furthering sustainable development by the year 2010. The analysis acknowledges that, as stated by Agenda 21 and the EU V Action Programme, sustainable development is a central issue. After considering the three main problems connected with the production and consumption of energy at the domestic level, the author describes syntetically the level of implementation of the current policies on environmental protection and efficient energy use in four important sectors (electricity, transport, industrial and household), underlining the main obstacles encountered on the sustainability path. The essential features of a strategy aimed at the sustainable development of the energy sector are finally presented. Such strategy is based on the reform of the price system in order both to account for the external costs and to promote technological innovation. The latter should be oriented to the improvement of energy efficiency in all sectors of production and use (CHP in particular) and to promotion of R and D of those renewable sources that are most suitable according to the social and economic Italian specificities [it

    2007-01-01

    After having recalled a dozen of reasons for some worries about energy supply security in Europe during the past months (oil price increase, intentional interruption of gas and oil deliveries by Russia respectively to Ukraine and Belarus, creation of a new CO 2 trading scheme, tensions on the European electricity markets, and so on), the author distinguishes and discusses those which are actually a threat to energy supply and those which are not. Then, he proposes a classification of these threats in relationship with the reasons for delivery interruption, production capacity limitation, or price increase. These reasons can be political situations and decisions, technical problems, commercial reasons. Then, the author examines what European policy makers can do to manage these risks and ensure energy supply security. This needs economic as well as political responses, coherence between domestic energy policies and energy supply security, and an efficient foreign policy based on a multilateral approach

    2016-01-01

    Climate protection and the expansion of renewable energy sources have been an important topic since the turn of the century. Due to the clear commitment to climate protection in Europe and the associated strong promotion of renewable energies, considerable changes are taking place in the electricity industry. However, these new forms of production lead to higher volatility in the electricity system. In addition, the expansion of renewable energy sources pressurized the conventional power plants. Their profitability is jeopardized, resulting in shutdowns and decommissioning, whereby 'secured' production forms are eliminated and the possibilities for intervention in the network operation are reduced. Due to its age structure (30% older than 30 years), the transmission network is not designed for the new requirements of this fundamental change in the production structure and the increasingly short lead times on the electricity market. This leads to an increase in bottlenecks and congestion management costs. A sustainable solution to recurring bottlenecks can only be achieved by means of adequate grid expansion. However, grid expansion is usually much slower than the creation of renewable generation units. Moreover, energy policy, market economy, environmental and climatological objectives are currently not coordinated, which leads to an increase in the network load and to the reaching of the physical limits. Therefore, planning and analysis of the requirements as well as the consideration of the electricity system including the electrical networks is of enormous importance. In order to achieve a holistic picture of the requirements of grid expansion, the APG Network development plan for the next ten years is based on the APG Masterplan, the calculations in the TYNDP (Ten Year Network Development Plan) and the requirements of the network partners. All these tools make it possible to recognize the future requirements for the transmission structure at an early

    Full Text Available The article analyses the induction process of technological innovations that consider economic, social and environmental concerns throughout the supply chain, in accordance with the proposals of sustainable development. Specifically, it examines the role of focal companies as innovation inductors for their supply chains. The article presents a debate with regards to innovation, sustainability and supply chain management and analyses the concept of sustainable innovation, as well as management models that bridge the gap between these themes. A case study conducted with a cosmetics company of Brazilian origin and presence in Latin America, is presented. This case study demonstrates that sustainable innovation driven by the focal company requires the engagement of its suppliers in order to reduce the negative social and environmental impacts throughout the product’s life cycle. Moreover, it illustrates that is possible to implement innovations that generate net social and environmental benefits for all members of the supply chain.

    With the background of the threatening global warming that requires a reduction of greenhouse gas emission by 20 % until 2010 und by 80% until 2050 in Germany, t is reasonable to consider local or municipal climate protection activities. A climate protection politics ''from the bottom'' is not only contributing to a real greenhouse gas reduction, but also triggering the stagnant international climate politics and enhances the sustainable development on a local level. Due to this fact amongst others the Enquete commission of the German Bundestag ''sustainable energy supply under the conditions of globalization and liberalization'' identifies the municipal climate protection activities as important part within the mix of measures that will allow the initiation of an alteration of the actual energy system toward a sustainable energy supply in the long-run. The consequences of globalization and liberalization on the municipal level have not yet been discussed or considered by the Enquete commission. This thesis analyses the conditions induced by the globalization and liberalization on the municipal climate protection activities as constituent of a sustainable energy supply. The project is focusing on the municipal actors and the public utility companies as central point of the considerations.

  1. Security of supply and regulation of energy networks

    International Nuclear Information System (INIS)

    Jamasb, Tooraj; Pollitt, Michael

    2008-01-01

    In recent years, the security of energy supplies has re-emerged as a central issue in the energy policy arena in the UK and elsewhere. This re-emergence takes place against a backdrop of increased liberalisation of the energy markets, so that security of supply needs to be revisited within this context. Security of supply is multifaceted, but is often discussed in terms of physical availability of energy sources and their commodity price risk. This paper discusses the relationship between security of supply and network regulation-that is, how the energy networks, and appropriate regulation of them, can contribute to security of supply in liberalised energy sectors. Energy networks are predominantly natural monopolies and as a result are generally subject to regulatory oversight. We discuss a range of issues and trends that pose challenges and opportunities to network regulation and which call for new and innovative measures. The paper identifies a number of areas where network regulation can play a significant role in increasing the security of supply of future energy systems

  2. Stimulating Investments in Energy Efficiency Through Supply Chain Integration

    2018-04-01

    Full Text Available Attention to energy efficiency is recently experiencing substantial growth. To overcome the several barriers currently existing that represent an obstacle to the successful implementation of the wide set of energy efficiency measures available, the cooperation among members of a supply chain offers a huge potential. In supply chains, in addition to the traditional coordination of the operations, the members may also share financial resources or act jointly on the capital market. This study presents a two-stage supply chain model considering the opportunity to invest in new energy efficient technologies which are affected by learning effects: the member of the supply chain with better energy performance and/or better financial conditions may find it more profitable to invest in the development of the energy efficiency of its partner. The objective of the model is to determine the optimal investment for each supply chain member so as to maximize the Net Present Value of the supply chain. The impacts of the proposed joint decision-making are investigated through some numerical analysis and managerial insights are proposed: the joint decision-making process on the financial flows for the energy efficiency investments results are especially advantageous (up to a 20% increase of the supply chain Net Present Value when members have different access to capital, which could be the result of different economic conditions in companies’ countries, as well as different credit policies or different credit ratings.

    Energy supply is a major source of greenhouse gas emissions. In the long term these emissions will have to be greatly reduced (especially in the industrialised countries where reductions on the order of 50-80% will be needed) in order to stabilise the greenhouse gases in the atmosphere. Such a reduction is very ambitious and given the inertia of the energy supply system, the path to this goal should preferably be set out immediately. The perspective for thinking about this problem is sustainable development. We will elaborate on the perspective starting from the positive results of the Netherlands governmental research programme on sustainable technological development. The resulting approach or method of this programme can be summarised in five golden rules, which will be explained. The core of the method is the development of a vision regarding a sustainable future. In our case this vision is based on a step-by-step approach towards a climate neutral and possibly renewable energy supply. The costs for emission abatement are assumed to increase in each step. For each step we will present a general picture of the expected changes in the supply system. Such a picture is not the only conceivable reality for energy supply but is an indicative framework. These frameworks are useful tools to structure the discussion about the future of energy supply. We will show that the vision not only leads to drawing general conclusion but also has led to a real project which deals with the development of technologies to produce climate neutral energy-carriers.

    Environmental Design is becoming an increasingly significant agenda for many manufacturing companies and yet there is no standard to their approaches, strategies or their levels of execution. Applying Design for Environment (DfE) methodologies to develop a more sustainable supply chain has formed procedures and techniques which allow designers to integrate these methods with environmental supply chain management. Design for Environment as a Tool for the Development of a Sustainable Supply Chain aims to define relevant target specifications for a product throughout its life cycle; from conception and design to the end of its operating life.  Be considering this new approach to the supply chain, environmental responsiveness can work in tandem with sounds business management. The usual focus on suppliers, manufacturers and customers is expanded in Design for Environment as a Tool for the Development of a Sustainable Supply Chain to include stakeholders such as government bodies and recycling companies.

    Amevi Acakpovi

    2016-01-01

    Full Text Available This paper proposes an original framework for optimizing hybrid energy systems. The recent growth of hybrid energy systems in remote areas across the world added to the increasing cost of renewable energy has triggered the inevitable development of hybrid energy systems. Hybrid energy systems always pose a problem of optimization of cost which has been approached with different perspectives in the recent past. This paper proposes a framework to guide the techniques of optimizing hybrid energy systems in general. The proposed framework comprises four stages including identification of input variables for energy generation, establishment of models of energy generation by individual sources, development of artificial intelligence, and finally summation of selected sources. A case study of a solar, wind, and hydro hybrid system was undertaken with a linear programming approach. Substantial results were obtained with regard to how load requests were constantly satisfied while minimizing the cost of electricity. The developed framework gained its originality from the fact that it has included models of individual sources of energy that even make the optimization problem more complex. This paper also has impacts on the development of policies which will encourage the integration and development of renewable energies.

    The long-term outlook for world energy demand and supply presented here by the International Energy Agency is intended to be only indicative of the possible evolution of worldwide energy trends, given that considerable uncertainty affects every energy forecast. The analysis, through two crude oil price scenarios and certain assumptions about world economic activity over the period to 2005, shows an estimate of both world oil demand and supply by area and total world primary energy requirements, by fuel and by area, for the projection period.

  12. How to Achieve Supply Chain Sustainability Efficiently? Taming the Triple Bottom Line Split Business Cycle

    Directory of Open Access Journals (Sweden)

    Matthias Klumpp

    2018-02-01

    Full Text Available For sustainable supply chains, specific concepts regarding how to efficiently improve sustainability are needed in a global comprehensive triple bottom line (TBL approach, especially for forwarders as central actors in supply chain design. Such specific advice is provided by reporting empirical DEA Malmquist index findings from seven large European forwarders regarding a TBL sustainability analysis from 2006 to 2016. A major obstacle in improving sustainability consists in the newly discovered fact that with the business cycle, the three TBL areas of economic, ecologic and social objectives for logistics are undergoing different up- and down-ward trends, making it very hard to improve all three simultaneously. Additional factors are identified in the characteristics of size and government influence regarding the sustainability efficiency of forwarders. This has important impacts on supply chain design like e.g., with selection criteria.

    On 27 March 2013, the European Commission published its first Renewable Energy Progress Report under the framework of the 2009 Renewable Energy Directive. Since the adoption of this directive and the introduction of legally binding renewable energy targets, most Member States experienced significant growth in renewable energy consumption. 2010 figures indicate that the EU as a whole is on its trajectory towards the 2020 targets with a renewable energy share of 12.7%. Moreover, in 2010 the majority of Member States already reached their 2011/2012 interim targets set in the Directive. However, as the trajectory grows steeper towards the end, more efforts will still be needed from the Member States in order to reach the 2020 targets. With regard to the EU biofuels and bioliquids sustainability criteria, Member States' implementation of the biofuels scheme is considered too slow. In accordance with the reporting requirements set out in the 2009 Directive on Renewable Energy, every two years the European Commission publishes a Renewable Energy Progress Report. The report assesses Member States' progress in the promotion and use of renewable energy along the trajectory towards the 2020 renewable energy targets. The report also describes the overall renewable energy policy developments in each Member State and their compliance with the measures outlined in the Directive and the National Renewable Energy Action Plans. Moreover, in accordance with the Directive, it reports on the sustainability of biofuels and bioliquids consumed in the EU and the impacts of this consumption. A consortium led by Ecofys was contracted by the European Commission to perform support activities concerning the assessment of progress in renewable energy and sustainability of biofuels.

    2010-01-01

    The critical topic of energy and the environment has rarely had such a high profile, nor have the associated materials challenges been more exciting. The subject of functional materials for sustainable energy technologies is demanding and recognized as a top priority in providing many of the key underpinning technological solutions for a sustainable energy future. Energy generation, consumption, storage, and supply security will continue to be major drivers for this subject. There exists, in particular, an urgent need for new functional materials for next-generation energy conversion and storage systems. Many limitations on the performances and costs of these systems are mainly due to the materials' intrinsic performance. We highlight four areas of activity where functional materials are already a significant element of world-wide research efforts. These four areas are transparent conducting oxides, solar energy materials for converting solar radiation into electricity and chemical fuels, materials for thermoelectric energy conversion, and hydrogen storage materials. We outline recent advances in the development of these classes of energy materials, major factors limiting their intrinsic functional performance, and potential ways to overcome these limitations.

  20. Perspective of nuclear fuel cycle for sustainable nuclear energy

    Nuclear power, on a life-cycle basis, emits about the same level of carbon per unit of electricity generated as wind and solar power. Long-term energy demand and supply analysis projects that global nuclear capacities will expand substantially, i.e. from 350 GW today to more than 1,500 GW by 2050. Uranium supply, spent fuel and waste management, and a non-proliferation nuclear fuel cycle are essential factors for sustainable nuclear power growth. An analysis of the uranium supply up to 2050 indicates that there is no real shortage of potential uranium available if based on the IIASA/WEC scenario on medium nuclear energy growth, although its market price may become more volatile. With regard to spent fuel and waste management, the short term prediction foresees that the amount of spent fuel will increase from the present 145,000 tHM to more than 260,000 tHM in 2015. The IPCC scenarios predicted that the spent fuel quantities accumulated by 2050 will vary between 525 000 tHM and 3 210 000 tHM. Even according to the lowest scenario, it is estimated that spent fuel quantity in 2050 will be double the amount accumulated by 2015. Thus, waste minimization in the nuclear fuel cycle is a central tenet of sustainability. The proliferation risk focusing on separated plutonium and resistant technologies is reviewed. Finally, the IAEA Project INPRO is briefly introduced. (author)

  1. Energy supply options for Lithuania: A detailed multi-sector integrated energy demand, supply and environmental analysis

    International Nuclear Information System (INIS)

    2004-09-01

    The Technical Co-operation (TC) project Energy Supply Options for Lithuania: A Detailed Multi-Sector Integrated Energy Demand, Supply and Environmental Analysis (LIT/0/004) was implemented 2001-2002 by a national team with support from the International Atomic Energy Agency (IAEA). The principal objective of the project was to conduct a comprehensive assessment of Lithuania's future energy supply options taking into consideration the early closure of the Ignalina nuclear power plant (Ignalina NPP). Lithuania, a country in transition to full membership of the European Union, has to comply with the energy acquis (Chapter 14). The 'acquis communautaire' (the body of common rights and obligations which bind all the Member States together) must be adopted by all applicant countries. Implementing the acquis requires not only adequate legislation, well functioning institutions (e.g. a regulatory body as required in the electricity and gas directives) or schedules for restructuring the energy sector but also measures to enhance energy supply security, improvement of energy networks, efficiency improvements throughout the energy system and compliance with European environmental standards. Within the overall context of the transition to EU membership, this study focuses on the future development of the electricity sector and the impacts on energy supply security and environmental performance of a closure of Ignalina NPP by 2009, a pre-condition for accession stipulated by the European Union. The project coincided with the preparation of the new National Energy Strategy for Lithuania and therefore was set up to support the strategy formulation process

Energy efficiency improvement and conservation opportunities in buildings, industry, electrical generation, and transport were also presented. The role of government in promoting energy efficiency was also discussed. Renewable energy opportunities were also offered for bio-energy; electrical generation; heating with renewables; and prospects for a renewables-fuelled Saskatchewan. Next, the report discussed technical, economic, political, and social barriers to progress. Several recommendations were offered in terms of energy efficiency and conservation; electricity generation; transportation; heating and cooling; industry; and financing change. 85 refs

  4. The Water Demand of Energy: Implications for Sustainable Energy Policy Development

    Directory of Open Access Journals (Sweden)

    2013-11-01

    Full Text Available With energy security, climate change mitigation, and sustainable development as three main motives, global energy policies have evolved, now asking for higher shares of renewable energies, shale oil and gas resources in the global energy supply portfolios. Yet, concerns have recently been raised about the environmental impacts of the renewable energy development, supported by many governments around the world. For example, governmental ethanol subsidies and mandates in the U.S. are aimed to increase the biofuel supply while the water footprint of this type of energy might be 70–400 times higher than the water footprint of conventional fossil energy sources. Hydrofracking, as another example, has been recognized as a high water-intensive procedure that impacts the surface and ground water in both quality and quantity. Hence, monitoring the water footprint of the energy mix is significantly important and could have implications for energy policy development. This paper estimates the water footprint of current and projected global energy policies, based on the energy production and consumption scenarios, developed by the International Energy Outlook of the U.S. Energy Information Administration. The outcomes reveal the amount of water required for total energy production in the world will increase by 37%–66% during the next two decades, requiring extensive improvements in water use efficiency of the existing energy production technologies, especially renewables.

  5. Development of a global electricity supply model and investigation of electricity supply by renewable energies with a focus on energy storage requirements for Europe

    Energy Technology Data Exchange (ETDEWEB)

    Troendle, Tobias Wolfgang

    2014-12-12

    Electricity supply at present requires about 38% of the global primary energy demand and it is likely to rise further in the coming decades. Facing major problems, such as limited resources of fuels and an ongoing anthropogenic climate change, a sustainable electricity supply based on renewable energies is absolutely vital. Wind and solar power will play an extensive role in future supplies but require energy storage capacities to meet electricity demand. To investigate the relationship of power plant mix and required energy storage capacity, a computer model based on global weather data has been developed to enable the simulation of electricity supply scenarios by up to ten different power plant types for various regions. The focus of the investigation has been on the energy storage requirements of an electricity supply for Europe by wind and solar power. The minimum required energy storage capacity for a totally weather dependent electricity supply occurs at a ratio of 30% wind and 70% photovoltaic (PV) power plant capacity installed. Thus, the required energy storage capacity rises from a transition of to-day's electricity supply to the afore-mentioned 100% renewable wind and PV scenario exponentially to about 150 TWh (3.8% of the annual electricity demand). The installation of additional excess wind and PV power plant capacity was seen to be an efficient way to reduce the required energy storage. Already 10% excess capacity lead to a reduction by 50% of the required storage capacity. To use different storage technologies in an optimised way in terms of storage capacity and efficiency, the storage tasks can be separated into a daily and a seasonal usage. While the seasonal storage capacity has to be about two orders of magnitude larger than the required capacity of the storage for the daily cycle, the sum of stored energy during one year is almost equal for the long and short time storage. In summary, an electricity supply by wind and PV power was shown to

    International Nuclear Information System (INIS)

    1981-01-01

    Recently published research reveals that the world energy requirement can and must grow more slowly than previously anticipated. In order to supply developing nations with the energy necessary for the expansion of their economies, energy saving and oil substitution assume greater significance in the industrialised countries such as the Federal Republic. Future fulfillment of the world energy requirement will be characterised by escalating costs for supply, especially for the current main energy carrier oil, on the one hand and by increased use of coal and nuclear energy as well unconventional fossils such as regenerative energies on the other. Nuclear energy and thus the electricity economy must play a key function in the future energy supply of industrial nations such as Federal Germany. Nuclear energy enables, both directly and indirectly, the substitution of oil in the heat market, supplies the process heat required for coal production and, due to the ease of storage or uranium, provides a hedge against fluctuations on the world energy market.

    International Nuclear Information System (INIS)

    Hoggett, Richard

    2014-01-01

    Highlights: • Energy systems need to decarbonise, provide security and remain affordable. • There is uncertainty over which technologies will best enable this to happen. • A strategy to deal with uncertainty is to assess a technologies ability to show resilience, flexibility and adaptability. • Scale is important and smaller scale technologies are like to display the above characteristics. • Smaller scale technologies are therefore more likely to enable a sustainable, secure, and affordable energy transition. - Abstract: This research explores the relationship between technology scale, energy security and decarbonisation within the UK energy system. There is considerable uncertainty about how best to deliver on these goals for energy policy, but a focus on supply chains and their resilience can provide useful insights into the problems uncertainty causes. Technology scale is central to this, and through an analysis of the supply chains of nuclear power and solar photovoltaics, it is suggested that smaller scale technologies are more likely to support and enable a secure, low carbon energy transition. This is because their supply chains are less complex, show more flexibility and adaptability, and can quickly respond to changes within an energy system, and as such they are more resilient than large scale technologies. These characteristics are likely to become increasingly important in a rapidly changing energy system, and prioritising those technologies that demonstrate resilience, flexibility and adaptability will better enable a transition that is rapid, sustainable, secure and affordable

    2005-04-01

    Environmentally Conscious Supply Chain Management (ECSCM refers to the control exerted over all immediate and eventual environmental effects of products and processes associated with converting raw materials into final products. While much work has been done in this area, the focus has traditionally been on either: product recovery (recycling, remanufacturing, or re-use) or the product design function only (e.g., design for environment). Environmental considerations in manufacturing are often viewed as separate from traditional, value-added considerations. However, the case can be made that professional engineers have an ethical responsibility to consider the immediate and eventual environmental impacts of products and processes that they design and/or manage. This paper describes ECSCM as a component of engineering ethics, and highlights the major issues associated with ethical decision-making in supply chain management.

    Full Text Available The integration of sustainability principles into the assessment of companies along the supply chains is a growing research area. However, there is an absence of a generally accepted method to evaluate corporate sustainability performance (CSP, and the models and frameworks proposed by the literature present various important challenges to be addressed. A systematic literature review on the supply chain at the corporate level has been conducted, analyzing the main strengths and gaps in the sustainability assessment literature. Therefore, this paper aims to contribute to the development of this field by proposing an assessment framework a leading company can adopt to expand sustainability principles to the rest of the members of the supply chain. This proposal is based on best practices and integrates and shares efforts with key initiatives (for instance, the Organizational Environmental Footprint from the European Commission and United Nations Environment Programme and the Society of Environmental Toxicology and Chemistry UNEP/SETAC; moreover, it overcomes important limitations of the current sustainability tools in a supply chain context consistent with the circular economy, the Sustainable Development Goals (SDGs, planetary boundaries, and social foundation requirements. The results obtained create, on the one hand, new opportunities for academics; and, on the other hand, in further research, the use of this framework could be a means of actively engaging companies in their supply chains and of achieving the implementation of practical and comprehensive CSP assessment.

    The Ninth Session of the the Commission for Sustainable Development (CSD-9) in April 2001 provided an excellent opportunity for a full debate on the role of nuclear power in sustainable development, as part of its over-all discussion of energy, transport and the atmospheric change issues. On nuclear power, there were two important conclusions. First, countries agreed to disagree on the role of nuclear power in sustainable development. CSD-9's final text recognizes that some countries view nuclear power as incompatible with sustainable development while others believe it is an important contributor to sustainable development. For each case, the reasoning is presented in the text. The second conclusion, on which there was consensus agreement, is that 'the choice of nuclear energy rests with countries'. The arguments in favor of an important role for nuclear power role in sustainable development are that it broadens the resource base by putting uranium to productive use; it reduces harmful emissions; it expands electricity supplies and it increases the world's stock of technological and human capital. It is ahead of other energy technologies in internalizing all externalities, from safety to waste disposal to decommissioning - the costs of all of these are already included in the price of nuclear electricity in most countries. The complete nuclear power chain, from resource extraction to waste disposal including reactor and facility construction, emits only two to kilowatt-hour -- about the same as wind and solar power and two orders of magnitude below coal, oil, and even natural gas. In addition, nuclear power avoids the emission of many other air pollutants, such as SO 2 , NO x and particulates

    In order to assess the sustainable development of China’s energy objectively and accurately, we need to establish a reasonable indicator system for energy sustainability and make a targeted comprehensive assessment with the scientific methods. This paper constructs a comprehensive indicator system for energy sustainability from five aspects of economy, society, environment, energy resources and energy technology based on the theory of sustainable development and the theory of symbiosis. On this basis, it establishes and discusses the assessment models and the general assessment methods for energy sustainability with the help of fuzzy mathematics. It is of some reference for promoting the sustainable development of China’s energy, economy and society.

    Full Text Available The growing trend market of fresh products is driven by a consumer oriented to new lifestyles and environmental issues. The berries market in Europe represents a good example of a consumer driven supply chain, due to the capacity to answer all the sequences of the system. To explore the process developed by fruit growers’ associated groups in Italy, the research is organized into four stages. The first stage provides a review of the organization of the fresh fruit supply chain (FFSC and the need to innovate it in light of the driven demand. The second section focuses on the innovation displayed towards storing, managing and maintaining the quality of fruit during the supply. The third section considers the case study. The manuscript concludes by summarising the main results and discussing the implications for future research. The use of a modified active packaging system (MAP with “green” films has enabled the maintenance of the quality of the fruits for two months, as well as the presence of the company blueberries market for longer periods, and has finally led to improving the exports, thus reaching new European countries, increasing the turnover of the associated group and better remuneration for the fruit growers as a consequence.

    Highlights: • Sustainable resource planning with the consideration of expected transmission network expansion. • Incomplete information non-cooperative game-theoretic method for GEP. • Maximizing utility value whiling considering merits of having various generation portfolios. • Minimizing risk of investment using renewable generation options. • Application of the stochastic approach for evaluating the unpredictability of opponent payoffs and commodity values. - Abstract: This study investigates the role of sustainable energy volatility in a market participant’s competitive expansion planning problem. The incomplete information non-cooperative game-theoretic method is utilized in which each generation company (GENCO) perceives strategies of other market participants in order to make a decision on its strategic generation capacity expansion. Sustainable generation incentives, carbon emission penalties, and fuel price forecast errors are considered in the strategic decisions. The market clearing process for energy and reserves is simulated by each GENCO for deriving generation expansion decisions. A merit criterion (i.e., the utility value) is proposed for a more realistic calculation of the expected payoff of a GENCO with sustainable energy resources. Finally, the impact of transmission constraints is investigated on the GENCO’s expansion planning decision. The case studies illustrate the effectiveness of the proposed method

    Full Text Available The textile and clothing industry generates much pollution and consumes a large amount of resources. Improper uses and disposal of clothing products make the problems much more severe. Fast fashion products shorten the valid lifecycle and generate more waste than regular clothing products. Considering the features of fashion products, a system of a rent-based closed-loop supply chain is developed to improve the sustainability of fashion products. The supply chain processes (fashion design and manufacturing, laundry, logistics and disposal, the operations management issues (inventory management, closed-loop logistics, human-clothing matching, booking system and the rental pricing and the sustainability promotion aspects (customization, responsive system, culture and policy aspects are investigated by devising sustainable strategies. The rationalities of the developed system and strategies are reviewed and elucidated in detail. The results may contribute to building sustainable closed-loop fashion supply chains, the related information systems and operational and managerial mechanisms.

    Facing global climate change and scarce petroleum supplies, the world must switch to sustainable energy systems. While historical transitions between major energy sources have occurred, most of these shifts lasted over a century or longer and were stimulated by resource scarcity, high labor costs, and technological innovations. The energy transition of the 21st century will need to be more rapid. Unfortunately, little is known about how to accelerate energy transitions. This article reviews past transitions and factors behind them, along with their time frames. Three modern case studies are discussed: Brazil, which shifted from an oil-based transportation system to one based on sugarcane-ethanol (success); France, which shifted from oil-fired electric power to nuclear power (success); and the United States, which attempted to shift from foreign oil to a mix of domestic energy resources (failure). Lessons from these attempts to govern energy transitions are discussed. Several policy instruments to accelerate a transition are identified, though even under ideal circumstances a global energy supply transition will be very slow. Given the need to simultaneously implement programs in countries with different political economies, a greater focus on energy efficiency, promotion of Smart Grids, and possibly a new treaty should yield more timely results. - Highlights: → We review the historical evidence on major energy transitions worldwide. → Case studies are presented of successful energy transitions in Brazil and France. → The United States provides an example of an unsuccessful energy transition. → We argue that a transition focused on energy efficiency can occur much more rapidly.

  13. Energy Supply System for Industrial Poultry Houses

    Sit M.L.

    2016-04-01

    Full Text Available The gas engine driven carbon dioxide heat pump designed for providing the heat, cold and electricity for industrial poultry house is proposed. The scheme differs from the known by using recuperative heat exchanger installed between the exhaust air duct of poultry house and heat pump evaporator and the heat curtain installed on the air duct after the evaporator. The air coming into the poultry house after the regenerative heat exchanger is supplied to the heat pump gas cooler. The heat pump produces heat of the required parameters of the input air and water for watering of poultry, space heating, etc. Heat pump compressor is driven by gas engine (GPA, by natural gas or biogas. The part of the gas-piston engine heat is used for adjusting the optimal heat pump mode and for regeneration of the absorbent in an evaporative cooler. The proposed technical solution of the above scheme provides a higher COP of the heat pump. Installing of heat curtain does not require the use of non-freezing solution to prevent icing of the air outlet of heat pump evaporator. The latter allows producing, besides electric power and heat, still cold (with the use off the adsorption-refrigerating machine and provide drying air inlet evaporative cooler (if necessary.

    Full text: Nuclear energy is an established component of electricity supply worldwide (16%) and in particular in OECD (nearly a quarter). It is supported by a mature industry benefiting from extensive experience (more than 8 000 reactor years of commercial operation) and dynamic R and D programmes implemented by governments and industries. Existing nuclear power plants are competing successfully in deregulated electricity markets owing to their low marginal production costs, their technical reliability (availability factors exceeding 80% in many countries) and good safety performance. Stringent safety requirements and radiation protection regulations in place in OECD countries allow potential impacts of nuclear energy facilities on human health and the environment to remain extremely low. Furthermore, nuclear energy, a nearly carbon free source, contributes to alleviating the risk of global climate change (worldwide, GHG emissions from the energy sector are already 8% lower than they would be without nuclear energy). Issues related to high-level waste management and disposal are being addressed in comprehensive, step by step approach. Progress towards the implementation of deep geological repositories is being demonstrated (e.g., Yucca Mountain in the US, Olkiluoto in Finland) and research on innovative fuel cycles aiming at partitioning and transmutation of minor actinides is being actively pursued. Up to 2010-2020, nuclear energy will maintain its role mainly through capacity upgrade and lifetime extension of existing plants, in many cases the most cost effective means to increase power capacity and generation. Examples are provided by utility policies and decisions in a number of OECD countries (e.g., Spain, Sweden, Switzerland, UK, US). Although only few new units are being or will be built in the very near term, their construction and operation is bringing additional experience on advanced evolutionary nuclear systems and paving the way for the renaissance of

    Monica Carvalho

    2012-11-01

    Full Text Available This paper reports on early work and concept development for Optimal Mine Site Energy Supply, where the specific energy supply requirements and constraints for mineral production operations are considered against methodologies that have been applied for other sectors and in other energy policy regimes. The primary motivation for this research is to help ensure that Canadian mineral producers will achieve reduced production costs through improvements in the efficiency with which they consume energy resources. Heat has not yet been considered for the mining sector in an integrated manner, which makes polygeneration of great interest. The methodology that optimizes configuration of polygeneration systems for mine sites has not been reported before. The variety of mining circumstances, temporal variations in energy prices, institutional inertia, and conservatism in design for mines are some of the reasons for this. This paper reviews some aspects of precedent energy management practice in mineral operations, which highlights energy challenges characteristic of the sector and sets out the initial formulation of optimal mine site energy supply. The review indicates the additional benefits of energy supply systems for mine sites that concurrently meet all utilities.

    2017-10-01

    Full Text Available Sustainability in the supply chain is becoming more and more important for industrial enterprises in different sectors. This research article focuses on construction supply chains (CSCs in the Engineer-to-Order (ETO industry, where every product is almost unique based on specific customer needs and requirements. The development of methods and approaches for more sustainable supply chain management in construction is becoming even more important. Engineering, fabrication of parts and their installation on-site are not always well synchronized in ETO supply chains. The results of such supply chains are long lead times, inefficient material transport and high and uncontrolled levels of work-in-progress (WIP. This article describes a conceptual approach to synchronize demand on-site with supply in manufacturing using the CONstant Work In Progress (ConWIP concept from Lean Management to achieve Just-in-Time (JIT supply. As a result, sustainable supply chains in ETO enterprises, with optimizations from an economic, ecological and social point of view, can be designed. The approach has been validated in an industrial case study.

    Consequences of global warming are appearing much faster than assumed just a few years ago and irreversible ”tipping points” are few years ahead (IPCC, 2007; Hansen et al., 2008; Kopp et al., 2009). Despite long and tedious preparations for COP15 in December 2009 the final result (Copenhagen Accord......, 2009) lacked sufficient concrete commitments for reduction of greenhouse gases (GHGs) after 2012 when the Kyoto Protocol expires. Human activities in their present form are strongly dependent on the supply of energy. A dominant part of the global energy supply is based on fossil fuels and a dominant...... part of the climate change is due to emission of CO2 from the use of fossil fuels. For simplicity, this paper focuses on CO2 emission from fossil fuels, but CO2 from deforestation as well as methane (CH4), laughing gas (N2O) and a number of industrial greenhouse gases should be included in a more...

    The production and use of biomass for energy has both positive and negative impacts on the environment. The environmental impacts of energy crops should be clarified before political choices concerning energy are made. An important aid to policy-making would be a systematic methodology to assess the environmental sustainability of energy crops. So far, most studies on the environmental aspects of energy crops deal mainly with the energy production of the crops and the possible consequences for CO 2 mitigation. The Dutch Centre for Agriculture and Environment (CLM) has developed a systematic methodology to assess the ecological and socio-economic sustainability of biomass crops. The method is best described as a multicriteria analysis of process chains and is very much related to Life Cycle Assessment (LCA). Characteristics of our methodology are the use of: definition of functional units; analysis of the entire lifecycle; definition of yield levels and corresponding agricultural practices; analysis of both ecological and economic criteria; definition of reference systems; definition of procedures for normalisation and weighting. CLM has applied the method to assess the sustainability of ten potentially interesting energy crops in four European regions. The results are used to outline the perspectives for large scale production of biomass crops with regard to the medium and long term land availability in Europe. For the crops considered, net energy budget ranges from 85 GJ net avoided energy per ha for rape seed for fuel to 248 GJ net avoided fossil energy per ha for silage maize for electricity from gasification. The methodology of the tool and its results were discussed at the concerted action ''Environmental aspects of biomass production and routes for European energy supply'' (AIR3-94-2455), organised by CLM in 1996. Major conclusions of the research: multicriteria analyhsis of process lifecycles is at present the best available option to assess the ecological

  20. Carbon-energy tax and sustainable development

    Ter Brugge, Marc.

    1994-01-01

    In 1992 the European Commission made a proposal for a carbon-energy tax to be introduced in Member States of the European Union (EU). So far, this proposal for a coordinated international response to the problem of global warming has met with a great deal of unwillingness among the Member States. During the first half of 1994 the Greek Chairmanship of the European Union will make another attempt to reach consensus. There does not seem to be much hope, however, that European countries will consent in the introduction of a EU-wide tax on carbon and energy. The Dutch government, in the mean time, has announced to introduce an energy tax for small users in 1995. In this paper InZet draws attention to the consequences for developing countries of the introduction of an energy tax in the industrialised countries. InZet strongly believes that instruments aimed at dealing with global environmental problems such as the greenhouse effect should have a global, integral focus. These instruments should be screened on their consequences for sustainable development in developing countries. Options for a more sustainable energy use in developing countries should form an integral part of energy policy instruments in the industrialised countries. The paper is structured as follows. In Chapter 1 an introduction to the phenomenon of global warming is given and the role of carbon/energy taxes in reducing CO 2 emissions is outlined. In Chapter 2 a definition of sustainable development and the means by which it can be supported in the South are discussed. Chapter 3 provides a description of various carbon/energy taxes, and in Chapter 4 the conclusions are given as well as several policy recommendations. 75 refs
