This paper systematically studies on how to make “water energy sources market compensation policy”, “the economic compensation policy for relevant interest subjects” and “the ecological compensation policy of basin ecological water.” So, it is necessary to exert the complementary function between market compensation and government compensation by the means of economic compensation and to establish the ecological compensation policy of basin ecological water, which is beneficial to coordinating the stakeholders’ interests of cross-region or inter-basin. And it is important and significant to establish constantly perfected ecological compensation policy among the micro subjects on water energy resources development, so as to coordinate interest relationships among various subjects and finally reach the aim of sustainable use of water energy resources and environmental protection as possible.展开更多

The use of energy conservation emission reduction policies to promote industrial restructuring and upgrading and thus facilitate energy conservation and emission reduction is one of the important strategies of environmental management in China. Based on the systematic collection of 1,195 energy conservation emission reduction policies, we discuss the influence of individual measure and measure synergy of energy conservation and emission reduction policies respectively. The results show that the energy conservation and emission reduction policies have a significant effect on the overall promotion of industrial upgrading. The financial measures and guidance measures have a positive impact;the financial measures and guidance measures have significantly positive effect; however, the administrative measures, fiscal tax measures, and other economic measures do the opposite; the positive effect of the synergy of guidance measures and financial measures is greater than the negative effect of considering only the synergy of fiscal tax measures and other economic measures, and significantly greater than the negative effect of the synergy of administrative measures, fiscal tax measures, and other economic measures. We should strengthen and emphasize the use of the measure that has positive effect on industrial structure restructuring and upgrading individually and synergistically.展开更多

A key subject in this quest is the future of automobile, with possibilities on powering ranging from biofuels to Hydrogen Cars (HC), to Electric Vehicles (EV). In turn, the latter is closely connected with the need to deploy Renewable Energies (RE) for electricity generation. Within such new situation, countries and governments are aware that there are new tools for fighting Global Warming (GW), and new policies could be established for winning this battle against CO2. All these initiatives will affect the future of energy corporations, notably hydrocarbon companies;and it should be noted that it will be difficult for the companies to define long-term strategies if energy policies convey upheavals, sudden changes in promoting alternatives and interruptions on activities. Hence, it is very important to adopt energy policies allowing a smooth evolution of the companies’ activities to the new energy model. After analyzing the alternatives with a forecasting-backcasting methodology, an “eclectic approach” is proposed, with the Plug-in Hybrid car with Flexible Fuel (PiHFF) as the central paradigm in the coming promoting policies.展开更多

In order to ensure the validity of policy-making,this work firstly exerts a method to do cost-benefit analysis for three kinds of technologies such as building-integrated solar hot water (BISHW) system,building-integrated photovoltaic (BIPV) technology and ground water heat pump (GWHP). Through selecting a representative city of every climate region,the analysis comes into different results for different climate regions in China and respectively different suggestion for policy-making. On the analysis basis,the Ministry of Construction (MOC) and the Ministry of Finance of China (MOF) united to start-up Building-integrated Renewable Energy Demonstration Projects (BIREDP) in 2006. In the demonstration projects,renewable energy takes place of traditional energy to supply the domestic hot water,electricity,air-conditioning and heating. Through carrying out the demonstration projects,renewable energy related market has been expanded. More and more relative companies and local governments take the opportunity to promote the large scale application of renewable energy in buildings.展开更多

During morning break 14 girls and 11 boys were provided with 160 ml of semi-skimmed milk or153 gof apple in a randomised crossover manner. Visual analogue scales were used to record hunger, prospective food consumption and fullness, immediately before and after breakfast, immediately before and after the mid-morning snack, and every 60 min until 21:00 on each day. School dinner/packed lunch energy intakes were assessed 90 min following the mid-morning snacks, in addition to evening energy intake. Children felt less hungry and could eat less when apple was consumed, however lunch and evening energy intakes were not different. Fluctuations in appetite did not translate into differences in energy intake therefore both milk and fruit should be promoted as mid-morning snacks in primary schools.展开更多

In order to extend the lifetime of the terminal, the limited energy must be utilized in an efficient manner. In this paper, under the constant transmission power scenario, we propose an Energy Efficient Transmission Policy (EETP) which is derived by using Markov Decision Process (MDP). The simulation results show that compared with the Threshold Transmission Policy (TTP), the proposed policy can reduce the energy consumption significantly, while satisfying the performance demand at the same time.展开更多

This paper attempts an examination of renewable energy policies aim of finding out how relevant and effective they have been in the Nigeria energy mix. Research shows that the implementations of these renewable policies are not fully effective as a result of several constraints, such as the lack of a supporting legislation, inadequate funding, and absence of a regulatory agency to oversee the development of renewable energy sources. Presently only policies exist for renewable energy in Nigeria. The absence of an effective legislation in renewable energy may hinder the efficient and full utilization of renewable energy in Nigeria. This paper argues for the enactment of an enabling renewable energy law as well as the establishment of a renewable energy agency saddled enforcement of the law, so as to hasten the rapid development and growth of renewable energy utilisation in Nigeria.展开更多

It is generated or stored by a variety of small devices commonly referred to as distributed energy resources (DER);the definition also extends to include stand-alone systems completely isolated from the public networks. The contribution made by independent power producers (IPP’s) through deployment of DER in the African energy market is critical to fast-tracking the deployment of renewables, diversification of the energy mix and enhancing access to modern and clean energy. There is need to develop policy mechanisms aimed at enhancing the current positive drive in the energy market;and this has been observed to be a driving factor in countries which have developed appropriate policy strategies. This paper presents the concept of DE in detail and how it could complement efforts to addressing the current energy crises in Southern Africa;it also looks at policy developments in Africa and presents the scenarios in the two southern African countries of South Africa and Botswana. The research is based on an extensive review of literature on the subject matter, consultations with stakeholders as well as feedback from the Learning Network for Sustainable Energy Systems (LeNSes) workshops.展开更多

Net-zero by 2050 is the international goal to limit global warming to 1.5 degrees Celsius and sustain the biosphere. Green renewable energy, including wind, solar, biomass and small hydro is abundant in Canada, with potential to satisfy demand with 100% green renewables. This paper compares the renewable power landscape across Canada’s provinces considering four factors—electricity energy mix, renewable energy targets (RETs), renewable energy standard offer programs (RESOPs), feed-in tariff (FITs) or community FITs (comFITs). The provinces with green renewable energy sources typically have enabling policies of RESOP, RETs and FITS, as Prince Edward Island, Nova Scotia, Ontario and New Brunswick do. In contrast, provinces with abundant oil and gas or large-scale hydro are without pro-renewable energy policies, nor community power options, excepting green renewables in Indigenous communities due to federal funding programs. Community green renewable power projects, such as the “Indigenous off-diesel initiative”, are creating jobs, community revenue and energy sovereignty, towards just and inclusive energy in off-grid Indigenous communities. To reduce climate change, fast-tracking net-zero electricity by 2035 is recommended with the prioritization of community renewable energy by RESOPs, FITs and comFITs. For the transportation and other sectors, banning of all fossil fuels before 2040 is needed. Finally, a long-term plan to reduce the negative impacts of hydroelectricity water fluctuation is needed, considering decommissioning some dams.展开更多

China’s transport industry has undergone remarkable developments in energy conservation through structural, technological and managerial measures. The paper analyzes energy-conservation policies and measures related to road transport in China. The paper also identifies constraints for these policies and measures. The transport management authorities face a series of difficulties associated with methods, costs, public awareness, and management systems. Suggestions for improvement are also offered, including promotion of energy-efficient private vehicles, advances in business vehicle energy conservation, exploiting the energy potential of urban traffic and infrastructure development for energy-efficient clean vehicles.展开更多

文摘Inspired by the green revolution,new energy vehicles(NEVs)provide a fresh,alternative mode of transportation for Chinese consumers mat reduce their reliance on traditional,gasoline/diesel-based cars.However,despite strong government support for NEVs in China,the level of uptake by consumers remains slow.Using Shanghai as a case study,this article provides a much-needed insight into local consumers'motivations to invest in NEVs through a survey of 100 Shanghai residents.Results indicate that current NEV promotion policies do not have a significant impact on the cognitive trade-off of NEV consumption under the"Integrated Consumer Behavior Model,"mainly due to inconvenient charging facilities,technical concerns regarding battery,higher prices,and wait-and-see attitudes regarding the pilot policy environment.Drawing on experiences from Sweden and New Zealand,this research serves to enhance knowledge on consumer attitudes towards NEVs and assist policy makers in developing more effective green consumption promotion campaigns in the future.
文摘The subjects of ecological compensation involve the nation, society, development enterprises of wa-ter-energy resources, as well as the location of resource itself. This paper systematically studies on how to make “water energy sources market compensation policy”, “the economic compensation policy for relevant interest subjects” and “the ecological compensation policy of basin ecological water.” So, it is necessary to exert the complementary function between market compensation and government compensation by the means of economic compensation and to establish the ecological compensation policy of basin ecological water, which is beneficial to coordinating the stakeholders’ interests of cross-region or inter-basin. And it is important and significant to establish constantly perfected ecological compensation policy among the micro subjects on water energy resources development, so as to coordinate interest relationships among various subjects and finally reach the aim of sustainable use of water energy resources and environmental protection as possible.
文摘The use of energy conservation emission reduction policies to promote industrial restructuring and upgrading and thus facilitate energy conservation and emission reduction is one of the 10 important strategies of environmental management in China. The use of energy conservation emission reduction policies to promote industrial restructuring and upgrading and thus facilitate energy conservation and emission reduction is one of the important strategies of environmental management in China. Based on the systematic collection of 1,195 energy conservation emission reduction policies, we discuss the influence of individual measure and measure synergy of energy conservation and emission reduction policies respectively. The results show that the energy conservation and emission reduction policies have a significant effect on the overall promotion of industrial upgrading. The financial measures and guidance measures have a positive impact;the financial measures and guidance measures have significantly positive effect; however, the administrative measures, fiscal tax measures, and other economic measures do the opposite; the positive effect of the synergy of guidance measures and financial measures is greater than the negative effect of considering only the synergy of fiscal tax measures and other economic measures, and significantly greater than the negative effect of the synergy of administrative measures, fiscal tax measures, and other economic measures. We should strengthen and emphasize the use of the measure that has positive effect on industrial structure restructuring and upgrading individually and synergistically.
文摘A portfolio of new energy technologies has emerged in the first decade of the 21st Century, and many of them could be used for re-structuring the energy sector towards Sustainable Development. A key subject in this quest is the future of automobile, with possibilities on powering ranging from biofuels to Hydrogen Cars (HC), to Electric Vehicles (EV). In turn, the latter is closely connected with the need to deploy Renewable Energies (RE) for electricity generation. Within such new situation, countries and governments are aware that there are new tools for fighting Global Warming (GW), and new policies could be established for winning this battle against CO2. All these initiatives will affect the future of energy corporations, notably hydrocarbon companies;and it should be noted that it will be difficult for the companies to define long-term strategies if energy policies convey upheavals, sudden changes in promoting alternatives and interruptions on activities. Hence, it is very important to adopt energy policies allowing a smooth evolution of the companies’ activities to the new energy model. After analyzing the alternatives with a forecasting-backcasting methodology, an “eclectic approach” is proposed, with the Plug-in Hybrid car with Flexible Fuel (PiHFF) as the central paradigm in the coming promoting policies.

文摘The purpose of this research was to inform primary school nutritional policy by identifying which mid-morning snack would be more beneficial to consume from an appetite control perspective. During morning break 14 girls and 11 boys were provided with 160 ml of semi-skimmed milk or153 gof apple in a randomised crossover manner. Visual analogue scales were used to record hunger, prospective food consumption and fullness, immediately before and after breakfast, immediately before and after the mid-morning snack, and every 60 min until 21:00 on each day. School dinner/packed lunch energy intakes were assessed 90 min following the mid-morning snacks, in addition to evening energy intake. Children felt less hungry and could eat less when apple was consumed, however lunch and evening energy intakes were not different. Fluctuations in appetite did not translate into differences in energy intake therefore both milk and fruit should be promoted as mid-morning snacks in primary schools.

文摘The pursuit of improved quality of life standards has significantly influenced the contemporary mining model in the 21st century.This era is witnessing an unprecedented transformation driven by pressing concerns related to sustainability,climate change,the just energy transition,dynamic operating environments,and complex social challenges.Such transitions present both opportunities and obstacles.The aim of this study is to provide an extensive literature review on energy transition to identify the challenges and strategies associated with navigating transformations in energy systems.Understanding these transformations is particularly critical in the face of the severe consequences of global warming,where an accelerated energy transition is viewed as a universal remedy.Adopting a socio-technological systems perspective,specifically through the application of Actor Network Theory(ANT),this research provides a theoretical foundation while categorising challenges into five distinct domains and outlining strategies across these different dimensions.These insights are specifically tailored for emerging market countries to effectively navigate energy transition while fostering the development of resilient societies.Furthermore,our findings highlight that energy transition encompasses more than a mere technological shift;it entails fundamental changes in various systemic socio-economic imperatives.Through focusing on the role of social structures in transitions,this study makes a significant and innovative contribution to ANT,which has historically been criticised for its limited acknowledgement of social structures.Consequently,we propose an emerging market energy transition framework,which not only addresses technological aspects,but also integrates social considerations.This framework paves the way for future research and exploration of energy transition dynamics.The outcomes of this study offer valuable insights to policymakers,researchers,and practitioners engaged in the mining industry,enabling them to comprehend the multifaceted challenges involved and providing practical strategies for effective resolution.Through incorporating the social dimension into the analysis,we enhance the understanding of the complex nature of energy system transformations,facilitating a more holistic approach towards achieving sustainable and resilient energy transitions in emerging markets and beyond.
文摘This paper analyses the evolution of China’s energy policies and reasons for their readjustment over time since 1978.Generally speaking,the foremost energy issue China faced during 1978-1993 was energy shortage,and China’s energy policies then focused on boosting energy construction and promoting energy investment etc.;from 1993 to 2005,China experienced rapid energy production growth and basically turned around the"demand outstrips supply"situation,and its energy policy priorities were then placed on adjusting the energy structure,rectifying the production order,and accelerating marketing reform etc.At the present stage,China faces three major energy issues:1)how to address environmental impacts in the process of energy production and consumption;2)how to ensure secure and stable energy supply;3)how to boost energy resource utilization efficiency.China’s energy policy priorities and measures will thus be changed accordingly.
文摘In wireless network, terminals are usually energy constrained. In order to extend the lifetime of the terminal, the limited energy must be utilized in an efficient manner. In this paper, under the constant transmission power scenario, we propose an Energy Efficient Transmission Policy (EETP) which is derived by using Markov Decision Process (MDP). The simulation results show that compared with the Threshold Transmission Policy (TTP), the proposed policy can reduce the energy consumption significantly, while satisfying the performance demand at the same time.
文摘Renewable energy utilisation is presently at its infancy in Nigeria despite its nation and global relevance. This paper attempts an examination of renewable energy policies aim of finding out how relevant and effective they have been in the Nigeria energy mix. Research shows that the implementations of these renewable policies are not fully effective as a result of several constraints, such as the lack of a supporting legislation, inadequate funding, and absence of a regulatory agency to oversee the development of renewable energy sources. Presently only policies exist for renewable energy in Nigeria. The absence of an effective legislation in renewable energy may hinder the efficient and full utilization of renewable energy in Nigeria. This paper argues for the enactment of an enabling renewable energy law as well as the establishment of a renewable energy agency saddled enforcement of the law, so as to hasten the rapid development and growth of renewable energy utilisation in Nigeria.
文摘This paper assesses the evolution of generation technology-mix in Australia,with specific emphasis on understanding how such evolution has been shaped by wider political and socioeconomic influences.This assessment is predicated on the argument that the contemporary,quintessentially techno-economic,policy discourse on renewable energy is deficient,as it ignores climacteric political and socio-economic influences on generation technology-mix.The methodological framework employed in this paper is informed by the core tenets of technological change theory.The assessment suggests that generation technology-mix in Australia has historically been overwhelmingly influenced by the underlying technological paradigm of the electricity industry;and that this technological paradigm essentially draws its imprimatur from the wider political and socio-economic contexts.By implication,it suggests that a rapid uptake of renewables will have widespread ramifications,extending into political,socio-economic and cultural realms of a society.Clearly,existing policy discourse-that tends to focus on technical potentials,cost competitiveness,externalities and risks of various renewable technologies-is deficient.A much broader discourse is needed.This paper also made an attempt to develop a basis for such a discourse by reviewing broader aspects of the Australian society that would be affected by a rapid uptake of renewables.

文摘Decentralised energy (DE), also known as distributed energy, refers to power generation and energy storage systems located at or near the point of use;and may also be connected to a local distribution network system or to a high voltage transmission system either directly or through a local distribution network system. It is generated or stored by a variety of small devices commonly referred to as distributed energy resources (DER);the definition also extends to include stand-alone systems completely isolated from the public networks. The contribution made by independent power producers (IPP’s) through deployment of DER in the African energy market is critical to fast-tracking the deployment of renewables, diversification of the energy mix and enhancing access to modern and clean energy. There is need to develop policy mechanisms aimed at enhancing the current positive drive in the energy market;and this has been observed to be a driving factor in countries which have developed appropriate policy strategies. This paper presents the concept of DE in detail and how it could complement efforts to addressing the current energy crises in Southern Africa;it also looks at policy developments in Africa and presents the scenarios in the two southern African countries of South Africa and Botswana. The research is based on an extensive review of literature on the subject matter, consultations with stakeholders as well as feedback from the Learning Network for Sustainable Energy Systems (LeNSes) workshops.
文摘A just and sustainable future requires green renewable power. Net-zero by 2050 is the international goal to limit global warming to 1.5 degrees Celsius and sustain the biosphere. Green renewable energy, including wind, solar, biomass and small hydro is abundant in Canada, with potential to satisfy demand with 100% green renewables. This paper compares the renewable power landscape across Canada’s provinces considering four factors—electricity energy mix, renewable energy targets (RETs), renewable energy standard offer programs (RESOPs), feed-in tariff (FITs) or community FITs (comFITs). The provinces with green renewable energy sources typically have enabling policies of RESOP, RETs and FITS, as Prince Edward Island, Nova Scotia, Ontario and New Brunswick do. In contrast, provinces with abundant oil and gas or large-scale hydro are without pro-renewable energy policies, nor community power options, excepting green renewables in Indigenous communities due to federal funding programs. Community green renewable power projects, such as the “Indigenous off-diesel initiative”, are creating jobs, community revenue and energy sovereignty, towards just and inclusive energy in off-grid Indigenous communities. To reduce climate change, fast-tracking net-zero electricity by 2035 is recommended with the prioritization of community renewable energy by RESOPs, FITs and comFITs. For the transportation and other sectors, banning of all fossil fuels before 2040 is needed. Finally, a long-term plan to reduce the negative impacts of hydroelectricity water fluctuation is needed, considering decommissioning some dams.
文摘Energy consumption for transport purposes has increased rapidly in China over the past decade. China’s transport industry has undergone remarkable developments in energy conservation through structural, technological and managerial measures. The paper analyzes energy-conservation policies and measures related to road transport in China. The paper also identifies constraints for these policies and measures. The transport management authorities face a series of difficulties associated with methods, costs, public awareness, and management systems. Suggestions for improvement are also offered, including promotion of energy-efficient private vehicles, advances in business vehicle energy conservation, exploiting the energy potential of urban traffic and infrastructure development for energy-efficient clean vehicles.
