The aim of this article is to address the regulatory framework as one of the key factors determining the success of creation of single market for renewable energy. No one could possibly argue that non-discriminative and consistent legal regulation plays a big role in the creation of a single market. Therefore, the question of legal capability to create the single market for renewable energy and the overall quality of present regulatory framework is at the centre of (...) this article. Our objective is to analyse whether the single market for energy produced from renewable sources can be created under current legal regulation of the European Union Therefore, the first part of the article analyses the competence of the European Union to regulate the renewable energy sector and division of legislative powers between the Member States and the European Union. The goal of the first part is to answer the question whether the European Union has the competence to regulate renewable energy market. The second part of the article analyses the legal framework of measures for the promotion of renewable energy production used in each Member State. The goal of the second part of this article is to answer the question – whether all renewable energy producers are in equal competitive position, notwithstanding different legal frameworks of the Member States.

This article is focused on analysing the present state of renewable electricity production and consumption coverage in Germany, concentrating on the intermittence of wind and solar energy production and considering the significance of the wind silence phenomenon. The development and promotion of renewable energy is a major goal set out by politicians of which one example is the German plan “Energiewende”. The author examines wind and solar energy complementarity and attempts assessing the possibility of basing (...) Germanys’ electricity production on renewable energy sources, without significant advancements in technology and changes in consumer behaviour. Using the analysis based on hourly data of consumption and production by source of electricity in Germany in 2016, the research addresses the issues of renewable energy source effectiveness, intermittence and points to the critical matter of periodical unavailability of wind and solar energy.

Renewable energy technology is often seen as a positive expression of technology, meeting energy needs with minimal environmental impact. But, by integrating nature with the ordering of the electric grid, renewables silently convert that nature into what Martin Heidegger referred to as standing reserve—resources of the technological commodity chain to be ordered, controlled, converted, and consumed on demand. However, it may be possible to mitigate the downsides of this process through a transition to more decentralized, local sources (...) of renewable energy operations and management that maintain awareness of the ways in which energy is generated and distributed.

Significant challenges confronting China include reducing carbon emissions, dealing with the resulting problems, and meeting various requirements for long-term economic growth. As a result, the shift in industrial structure best reflects how human society utilizes resources and impacts the environment. To meet China's 2050 net-zero emissions target, we look at how technological innovations, financial development, renewable energy investment, population age, and the economic complexity index all play a role in environmental sustainability in China. Analyzing short- and long-term relationships (...) using ARDL bounds testing, we used historical data spanning 1990–2018. According to the study's findings, the cointegration between CO2 emissions and their underlying factors was found. The deterioration of the environment directly results from financial development, increasing economic complexity, and population aging. Technical advancements, investments in renewable energy sources, and changes to the industrial structure all contribute to lower CO2 emissions. Granger causality results were also reliably obtained in this study. According to our findings in the fight against environmental problems, a key tool for meeting long-term sustainability goals is policy prescriptions that use technological innovations, renewable energy investment, and industrial structure.

The government of Ontario has adopted wind energy development as an alternative energy source. It enacted the Green Energy and Economy Act, May 2009, with the intention to fast track the approval process regarding industrial wind turbines. The Act legislated a centralized decision making process while removing local jurisdictional authority. Throughout this process, the government reassured the public of inexpensive and reliable electricity. This article explores the costs and benefits related to the renewable energy policy (...) established in Ontario, Canada. (shrink)

The mounting pollution burden has raised the need for renewable energy demand throughout the world. The study aims to explore the effect of public debt on renewable energy consumption for selected 23 Asian economies for the time period 1990–2019. Long-run empirical findings of the group-wise symmetric ARDL model reveal that increasing public debt results in declining renewable energy consumption. However, findings of the long-run group-wise asymmetric ARDL model reveal that positive shock in public debt (...) reduces renewable energy consumption, and negative shock in public debt results in increasing renewable energy consumption. The economy-wise empirical findings of the FMOLS model reveal that an increase in public debt results in increased renewable energy consumption in nine economies and decreased renewable energy consumption in six economies. The asymmetric FMOLS findings reveal that positive shock in public debt increases renewable energy consumption in nine economies and also decreases renewable energy consumption in nine economies. However, a negative shock in public debt increases renewable energy consumption in 12 economies and decreases renewable energy consumption in 5 economies. Additionally, this research provides numerous policy implications for renewable energy sources in Asian economies. Asian governments should use public debt for the consumption of renewable energy resources. (shrink)

Greenhouse gas emissions are adversely affecting the earth’s climate, a global common and a public good. The contribution of individual countries has a limited effect on the biosphere, implying that only globally coordinated efforts may result in significant climate improvements. The Rio Earth Summit (1992) and Kyoto Protocol (1997) are manifestations of international efforts to achieve sustainable development through efficient use of energy and incorporating more renewable sources in global economy. In this article, the author examines the (...) class='Hi'>energy-related emissions of greenhouse gases and the utilization of renewable energy sources in Canada with respect to Agenda 21 commitments. An overview of the results of Canada’s policies on climate change since Rio in terms of energy consumption, various sources of energy, and emission rates of greenhouse gases is also presented. It is concluded that the current plans of the Canadian government to deal with greenhouse gas emissions have not been effective. (shrink)

Concerns about energy security have dramatically increased since the terrorist attacks on September 11, 2001. If U.S. energy use follows business-as-usual projections, the energy system will become increasingly vulnerable. No quick fixes are available to make the United States energy independent. However, there are energy policies that promote efficiency and the use of renewable energy sources such as wind, biomass, geothermal, and solar can gradually reduce dependence on imported oil and natural gas and (...) reduce the vulnerability of the U.S. energy infrastructure to disruption of supplies or to attack. This article reviews recent analyses by the U.S. Energy Information Administration’s and by the Union of Concerned Scientists. These studies showthat efficiency and renewable energy investments can increase energy security while lowering consumer energy bills and reducing local and global environmental hazards. (shrink)

Contemporary research highlights multiple societal and environmental benefits in addition to potential economic advantages associated with renewable energy utilization. As federal and state incentives for investments in RE technologies become more prevalent, RE sources represent increasingly viable alternatives to established fossil fuel energy. RE utilization is recognized as a key component of “green” product innovation that helps firms reduce the environmental impact of production processes and diminish their ecological footprints and energy consumption. Yet, despite consistent evidence (...) that corporate sustainability initiatives are favorably associated with firm performance, the limited research that examines associations between RE initiatives and firm performance yields mixed results and an explicit link has yet to be established. Drawing on the natural resource-based view of the firm, we examine the association between RE utilization and firm financial performance over time. Annual ROI, Tobin’s Q, and operating margin for large U.S. firms identified as exceptional users of RE in the EPA’s Fortune 500 Top Green Power Partners list are compared with their respective industry medians over a 7-year period and post hoc bootstrapping and sensitivity analyses are performed to further validate the study findings. Our research advances current knowledge about the influence of RE utilization by demonstrating that top RE user firms consistently generated superior financial performance compared to their industry competitors. As such, the study findings lend credence to the existence of a business case that complements the societal and environmental benefits of RE utilization. (shrink)

Throughout the history of mankind, energy security has been always seen as a means of protection from disruptions of essential energy systems. The idea of protection from disorders emerged from the process of securing political and military control over energy resources to set up policies and measures on managing risks that affect all elements of energy systems. The various systems placed in a place to achieve energy security are the driving force towards the energy (...) innovations or emerging trends in the energy sector. Our paper discusses energy security status and innovations in the energy sector in European Union (EU). We analyze the recent up-to-date developments of the energy policy and exploitation of energy sources, as well as scrutinize the channels of energy streaming to the EU countries and the risks associated with this energy import. Moreover, we argue that the shift to the low-carbon production of energy and the massive deployment of renewable energy sources (RES) might become the key issue in ensuring the energy security and independency of the EU from its external energy supplies. Both RES, distributed energy resources (DER) and “green energy” that will be based on the energy efficiency and the shift to the alternative energy supply might change the energy security status quo for the EU.

The affective sciences are essential to research regarding sustainable transition towards renewable energy. We focus on important questions that should be addressed by affective science in relation to the siting of large-scale renewable energy projects like wind and solar. Considering the recent acceleration of the transition, a more holistic understanding of negative and positive emotional responses to energy development will be essential. This is particularly important as the least controversial sites begin to dwindle in number. (...) We break this commentary down into four primary question categories for future research. These are the causal relationships between emotional elicitations and their sources, dual processing through cognitive and affective response, affect and its relationship with place, and how all of these elements change over time.

With the stricter environmental regulations and diminishing fossil-fuel reserves, there is now higher emphasis on exploiting various renewable sources of energy. These alternative sources of energy are usually environmentally friendly and emit no pollutants. However, the capital investments for those renewable sources of energy are normally high, and there are also maintenance cost differences to be considered. Furthermore, due to the intermittency of some of these power sources, reliability issues should be addressed when integrating different (...) power sources. In this article, as an example, the design of hybrid generating systems comprising wind turbine generators, photovoltaic panels, and storage batteries is discussed based on multidisciplinary optimization. In this multisource generation system design, three design objectives are considered, that is, system cost, reliability, and pollutant emissions. (shrink)

Of the large industrial countries, Germany is clearly leading with regard to new renewable energy sources, occupying first rank in terms of installed capacity for wind energy and second for photovoltaics. This is not because of an exceptional natural resource base but because of public policy in this area, despite the fact that this policy was conducted in a lukewarm fashion until 1998. In any case, it led to a remarkable expansion of this sector. The Red-Green coalition, (...) in office from 1998 to 2005, developed the vision of achieving 50% and more of electricity generated from renewable energy sources by 2050, a goal that seems well accepted by the public but not by the established energy interests. There seems to be a good chance that the Conservative-Social Democratic coalition, which took office in November 2005, will continue this course. (shrink)

The reality of global warming from the buildup of fossil fuel carbon dioxide in the atmosphere is no longer in doubt. In retrospect, it was inevitable that the explosive growth of human carbon dioxide emissions, driven by population growth, industrialization and, most of all, by fossil fuel energy use, made it inevitable that human-induced warming would overwhelm climate change from all the other factors at some point. And we are at that point. I believe we can solve the climate/ (...) class='Hi'>energy problem, but it will not be easy. This problem will not solve itself through the invisible hand of the market. Relevant costs and values are not being captured. Particularly serious is that we are investing in the wrong infrastructures for a sustainable energy world. Exponential growth cannot be sustained indefinitely on a finite planet. We could, and I believe should, try to maintain 2 to 3 percent per year world GDP growth to the end of the century as carbon dioxide emissions are held constant, decreased, and eventually phased out by mid-century. This paper discusses some ideas that could work if we get serious. Colleagues and I propose as a goal that by mid-century renewable energy sources should supply roughly a third of the world's power; clean, safe and sustainable nukes another third; and coal gasification with CCS the final third. At the same time, we need to implement everything we have in our alternate energy arsenal immediately. (shrink)

Energy contributes significantly in almost all aspects of human life as well as economic activities and plays a crucial role in the infrastructural development of a county to alleviate poverty. Generating energy from a renewable source such as small hydropower through the application of pump operating as a turbine mode called Pump as Turbine is one of the best alternatives to provide clean and inexpensive energy. Using Pump as Turbine helps in generating reasonably priced hydroelectric power (...) for communities in underdeveloped counties. This study investigates the effects of internal flow behaviour and performance of Pump as Turbine under different rotational speed and flow rate. The rotational speed is an essential physical parameter as it affects the Pump as Turbine operation. A model-specific speed centrifugal pump model with head 32, flow rate of 12.5 and the rotational speed of 2900 rpm, has been selected for the study. Numerical simulations have been conducted using the k-ω turbulence model to solve three-dimensional equations. The pump mode experimental data were used to confirm the results for better analysis. The results predicted that vortex and turbulent kinetic energy increase per rotational speed increase. Also, at the higher rotational speed, very high recirculation of flow is detected at the blade suction chamber, although the pressure side has a smooth flow. This study provides beneficial information which will serve as a reference to help improve PAT performance along with selecting PAT for a small hydropower site. Future works will consider the impact of blade thickness and cavitation in Pump as Turbine. (shrink)

The hybridization of two or more energy sources into a single power station is one of the widely discussed solutions to address the demand and supply havoc generated by renewable production, heating power, and cooling power) and its energy storage issues. Hybrid energy sources work based on the complementary existence of renewable sources.

This paper presents an economic model of a microgrid system containing the CCHP system and energy storage considering the energy coupling and conversion characteristics, the effective characteristics of each microsource, and energy storage unit is proposed. The random forest regression model was optimized by the gravitational search algorithm. The test results show that the GSA-RFR model improves prediction accuracy and reduces the generalization error. The detail of the MG network and the energy storage architecture connected to the other renewable energy sources is discussed. The mathematical formulation of energy coupling and energy flow of the MG network including wind turbines, photovoltaic, CCHP system, fuel cell, and energy storage devices are presented. The testing system has been analysed under load peak cutting and valley filling of energy utilization index, energy utilization rate, the heat pump, the natural gas consumption of the microgas turbine, and the energy storage unit. The energy efficiency costs were observed as 88.2% and 86.9% with heat pump and energy storage operation comparing with GSA-RFR-based operation costs as 93.2% and 93% in summer and winter season, respectively. The simulation results extended the rationality and economy of the proposed model. (shrink)

Problems of fuel ethanol production have been the subject of numerous reports, including this analysis. The conclusions are that ethanol: does not improve U.S. energy security; is uneconomical; is not a renewable energy source; and increases environmental degradation. Ethanol production is wasteful of energy resources and does not increase energy security. Considerably more energy, much of it high- grade fossil fuels, is required to produce ethanol than is available in the energy output. About (...) 72% more energy is used to produce a gallon of ethanol than the energy in a gallon of ethanol. Ethanol production from corn is not renewable energy. Its production uses more non- renewable fossil energy resources in growing the corn and in the fermentation/distillation process than is produced as ethanol energy. Ethanol produced from corn and other food crops is also an unreliable and therefore a non-secure source of energy, because of the likelihood of uncontrollable climatic fluctuations, particularly droughts which reduce crop yields. The expected priority for corn and other food crops would be for food and feed. Increasing ethanol production would increase degradation of agricultural land and water and pollute the environment. In U.S. corn production, soil erodes some 18- times faster than soil is reformed, and, where irrigated, corn production mines water faster than recharge of aquifers. Increasing the cost of food and diverting human food resources to the costly and inefficient production of ethanol fuel raise major ethical questions. These occur at a time when more food is needed to meet the basic needs of a rapidly growing world population. (shrink)

A vexing modern conundrum is to be solved. The use of oil, gas, and coal is extremely short-lived as a historical phenomenon: a mere blink of an eye at a little more than 1% of total urban history of 10,000 years to-date. Yet current urban civilization is almost entirely based on it. And the fossil-fuel economy poses not only a massive security risk, it also lies at the root of the vast majority of urban sustainability problems. Fresh water depletion, air (...) pollution, widespread human fatalities can be directly traced to the excessive use of these dirty energy sources. Climate change, predominantly triggered by fossil-fuel combustion, only deepens the very questions the impending petroleum peak raises about the survivability of the global urban system. The fossil disease is a complex global pandemic. To many, conquering this pandemic is an extraordinary challenge of technology: of reengineering the manner in which urban civilization is powered, advancing a future envisioned in numerous studies since the 1970s. Yet foremost, this is a cultural, psychological, and political challenge. The global economy is systematically identified with its underlying fossil supply frameworks—it is a fossil economy. It is marked by an incendiary illusion: the celebration of abundance promised as achievable by all, driving virtually all aspects of contemporary culture. Yet it is also marred with enormous pockets of deprivation, and deep cracks of disbelief, criticism, and dissent. Reinforcing this challenge is the psychoeconomical transaction cost of change, the sheer inertia of an infernal development system, however short-lived it inevitably is. Despite all lip service paid to ‘energy savings’ and ‘environmentally sustainable development’ in urban policy documents and brochures across the globe, dominant political and financial interests demand that as much fossil fuel as possible is used, and as quickly as possible, to secure the highest possible profits for the most powerful, and in the shortest period of time. Hence many national governments and international bodies find it so difficult to place fossil-fuel replacement on the global agenda. It is easier to avoid this topic and talk about buffering, mitigating what are little else than subsidiary, flow-on effects and collateral outcomes of an unsolved energy conundrum: air, water and soil pollution, public health problems, deforestation or fresh water depletion. Rarely, if ever, is petroleum abuse clearly noted as a root cause. A historical revolution is in progress: the move from fossil fuels, nuclear power, and other forms of unsustainable energy use generation to a renewable and sustainable power base for urban communities, cities, towns, and villages. Many examples of positive initiatives encourage, and are testimony to the ability of cities and towns to perform as communities, and evolve into settings of greater independence from fossil and nuclear power sources. They carry the promise of greater energy autonomy based on renewable energy, of recapturing regional productivity, advancing local resources, and enabling new industries and employment opportunities.

This article is a reflection of the project ‘Welcome Aboard’, which I collaborated on in 2011, with two scientists Nicola Armaroli (Ist. ISOF/CNR, Bologna and Molecular Photoscience Group, Bologna) and Vincenzo Balzani (Department of Chemistry G. Ciamician, University of Bologna). The video establishes a dialogue based on Buckminster Fuller’s ‘World Game’ where they offer possible scenarios for our planet running under renewable energy sources. Ultimately, a democratic system of energy sharing, between consumers and suppliers, was proposed to (...) be put at the forefront. The article begins with David Bohm’s focus on how a collective thought process can have drastic affects on our society. He proposes that we recognize the ‘whole’ in which we live to avoid becoming a society of fragmented incoherency. Similarly, as an engineer Buckminster Fuller has devoted himself to finding an effective action to change the world through a global approach, which he calls a whole-system perspective. The technology of the Smart Grid, proposed in the dialogue between the two scientists of ‘Welcome Aboard’ in which every individual produces, shares and consumes energy (electricity), seems to be a new tool that could be combined with other technologies to provide a connectivity between human beings.

In general terms there are only three primary energy sources: fossil fuels, renewable energy, and nuclear fission. For fueling road transportation, there has been much speculation about the use of hydrogen as an energy carrier, which would usher in the “hydrogen economy.” A parallel situation would use a simple battery to store electricity directly in order to power vehicles. The efficiency of these two different approaches has been compared and shows that the hydrogen and fuel cell (...) system would consume nearly three times the primary energy required by a battery storage system. Successful introduction into the marketplace of the plug-in hybrid vehicle would eliminate the need for road vehicles to use petroleum fuels, at least for the majority of miles traveled. If electricity were to be generated primarily from sustainable primary energy sources, then road transportation would also become sustainable, resulting in an “electricity economy” rather than a “hydrogen economy.”.

This article offers a descriptive and analytic view of the different stages leading to the constitution of a corpus that is representative of the issues of climate and energy justice. Overall, the corpus contains over five million words and gathers reports, newsletters and web-pages dealing with the most equitable ways of moving to a low-carbon future in the aim of limiting climate change. It can be divided into six sub-corpora, according to types of discourse communities, and methods of constitution. (...) We begin by presenting the small Do It Yourself (DIY) corpora which were used as a starting point. Three discourse communities were selected to observe possible variation in their treatment of the issue: Non-Governmental Organisations (NGOs), United-Nation institutions, and the Renewable Energy Sector (RES). The sources are selected according to author, date, keywords in title. Using the concordance Antconc and WMatrix software we test the reliability of the corpora for their thematic content, terminology and lexical unit classification. Our first results enable us to confirm variation between the discourse communities. The discrepancy in sizes and the time-consuming nature of the initial DIY corpus constitution lead us to use BootCat to extend them, using keywords from the corpora as seeds to retrieve and download webpages. We thus contrast a more traditional approach to corpus building to web-as-corpus data gathering methods. We compare the results found in the BootCat corpora to test if they are as specific as those in the DIY corpora. This enables us to draw conclusions on the possible uses and advantages of relatively small corpora for the study of specialised discourse. (shrink)

This chapter helps explain why energy ethics has not prevailed, despite thousands of years of energy pollution–caused deaths. Section 1 outlines the harms created by fossil fuels and nuclear energy. Section 2 surveys environmental ethicists’ responses to these harms. Because energy harms are so obvious and well established, most environmental ethicists have not spent time arguing against them. Instead, as section 3 explains, most environmental ethics work on energy has been at the level of third-order (...) analyses—responding to those who attempt to justify continued use of dirty energy, often by saying other power sources are unavailable or too expensive. Sections 4 through 8 provide brief third-order ethical analyses of five major second-order ethical excuses for not moving to clean, renewable energy: namely, the readiness, intermittency, expense, regulation, and intention excuses. The final section outlines how future energy-related ethics research is likely to develop. Because other chapters in this volume address climate this one does not do so. (shrink)

Abstract Energy typically is discussed in terms of science, technology, economics, and politics. Little attention has been given to fundamental religious and ethical questions surrounding the upcoming transition to renewable energy. The essays in this thematic section seek to redress that deficiency. This introductory essay raises some key questions and summarizes various presentations on energy and religion, as these were held at the 2010 conference of the Institute on Religion in an Age of Science (IRAS). Some (...) presentations described the energy landscape and provided data and perspectives needed for sound policy. Others raised ethical and religious considerations for energy decisions as the transition from nonrenewable to renewable sources is faced. Some posed the challenges of the energy transition to religion itself. Yet others offered examples of sustainable energy use and/or promising sources for meeting future needs sustainably. At the conclusion of the conference, presenters crafted a common “Statement on Energy and Climate Change” that includes a “Call to Action.” The “Energy Statement” follows as an appendix. (shrink)

India dropped its target of 500 GW of renewable energy capacity fossil fuel sources by 2030. Its responsibilities the United Nations Framework Convention Climate Change [UNFCCC],and reducing radiations by one billion tonnes by the end of the decade at the COP26 conference, held in Glasgow in November 2022. Researchers are continually searching for inexhaustible and reasonable energy sources. Solar energy is one of the greenest sources of energy and is also one of the cleanest. The (...) most important factor in using solar energy is the location of the solar power plant. The main objective of this study is to find the best location for a new solar power plant in a specific region called Bundelkhand region of Uttar Pradesh in India. Here we offer an extension of ELECTRE III method as two-phase Pythagorean neutrosophic elimination and choice translating reality PN-ELECTRE-III) method to adapt with fuzzy, ambiguous, unsure, and indeterminate criteria. The Pythagorean neutrosophic numbers [PNNs] used by the group decision support system of PN-ELECTRE III to measure performance of the alternatives. The options are entirely outclassed in the subsequent stage in view of the past stage's evaluations of them. By defining PNN we describe the technique of indifference threshold functions, preference treshold and veto threshold functions, which provide a more stable basis to drop outranking relations. By calculating the concordance credibility, discordance credibility and net credibility degrees of each alternative, the ranking module of the PN-ELECTRE III approach is made simpler. In order to confirm the applicability of the strategy suggested in this paper, the location selection problem for solar plants is finaly solved. (shrink)

Vietnam is a vibrant and emerging South East Asian economy. However, the country faces a challenging task in meeting rising energy demand and the need to securitize energy while addressing the negative environmental impact of fossil fuel utilization. Growing concerns about sustainable development have led Vietnam to develop civilian nuclear energy for electricity generation. Nuclear power is widely recognized as a clean, mature and reliable energy source. Its inclusion in Vietnam’s energy mix by 2030 is (...) expected to supplement other energy sources from fossil fuel, hydropower plants, renewable resources and energy imports. Despite strong reservations in the aftermath of the Fukushima disaster, Vietnam has pursued its national nuclearization program. Civilian nuclear energy development has been widely regarded as a controversial issue, although it is intended for peaceful purposes and as a solution for long-term energy security. Anxiety over nuclear safety measures, inadequate nuclear regulatory mechanisms, lack of institutionalized radioactive waste management, the threat of nuclear accident, theft and terrorism, and nuclear proliferation have marred public perception. The apprehension towards nuclear energy development has raised serious questions on the ethics and risks of the technology. Using a qualitative approach of reviewing published scholarly research, we investigated the ethical and risk issues that manifest in civilian nuclear energy development in Vietnam. Our findings reveal that the conundrum of civilian nuclear energy revolves around balancing energy security, environment preservation and societal well-being with ethical and risk predicaments of nuclear energy.

The energy sector contributes approximately two-thirds of global greenhouse gas emissions. In this context, the sector must adapt to new supply and demand networks for all future energy sources. The ongoing transformation in the European energy field is driven by the ambition of the European Union to reach the climate objectives set for 2030. The main actions are increasing renewable energy production, adapting transition fuels like natural gas to reduce emissions, improving energy efficiency across (...) all economic sectors, prioritizing building, transportation, and industry, developing Carbon Capture and Storage technologies, and ensuring universal access to clean and affordable energy. The significant changes envisaged in the energy sector to increase renewable energy production and consumption require improved integration and more use of predictive tools to support stakeholders' decision-making processes. This article presents a case study to assess the performance of predictive models based on a Feed-Forward Neural Network architecture that employ Root Mean Squared Propagation as their optimization function in terms of choosing the most appropriate activation function for this kind of data input and output. The training and testing phases of the models use data about building energy consumption. The lowest training time and Root Mean Square Error values were similar for Rectified Linear Unit and Tanh activation functions. The model with the Rectified linear Unit activation function performed best. (shrink)

India’s energy demand is predicted to rise by 135% within a span of 20 years. Coping up with surging energy demands requires several reforms in both renewable and non-renewable sectors. Factors such as rising population, reduction in the cost of renewable energy technology and their effect on the nation’s GDP, can make policy making a herculean task and the justification for such policies, quite opaque to the public. Artificial Intelligence technology can help decision makers (...) to quickly draw conclusions from voluminous datasets under different heads. However, AI results need to be post-processed so that they are easily understood by the layperson. This paper focuses on using Sankey diagrams as a post-processing tool for AI systems. Policy formulation often requires an overall assessment of energy sources, production pathways, end used destinations and wastage encountered—these can be easily visualized with a Sankey diagram. For this work, a Sankey protocol was written out in a form where a prompt asks the user to supply information through a spreadsheet interfaced with a customized mobile app—a first anywhere in the subcontinent. India’s mobile sector is vibrant, and the paper presents a enabling the user to have a handle on the dynamics of energy distribution locally. The app gives an instant feel of the apportioned energy across grids, the projected changes for the next decade, the efficiency and feasibility of each sector and lastly a telling visual representation showing the main strengths and weaknesses in the energy sector.

This paper considers the environmental justice issues presented by the proposed open-pit lithium mine in Thacker Pass, Nevada (Peehee mm’huh). Unlike the environmental destruction wrought from fossil fuel extraction, lithium is used to create lithium-ion batteries for storing and using electricity from “green energy” sources. Can the potential reduction in carbon emissions resulting from the lithium mined morally and politically justify the destruction of the Pass’s sagebrush sea – a critical wildlife habitat and sacred land to the People of (...) Red Mountain? Justice issues of this kind (e.g., clashes between the “renewable energy” industry and indigenous rights) are likely to become more prevalent as the industrial economy transitions from fossil fuels to vastly more spatially extensive forms of energy production (e.g., wind and solar farms, hydroelectric dams, and biofuels). I consider the case through the concept of ecocide and explore how liberal political respect for eco-relational pluralism offers grounds on which ecocide ought to be prohibited in a fair and just society. The goal of this paper is to ensure that states, in the pursuit of environmental justice, proceed in a manner aligned with their commitment to liberalism, by refraining from prioritizing economic growth and development at the expense of other reasonable conceptions of the good.

Energy poverty is a problem that affects developed and developing economies, and its mitigation is of great significance to social welfare. EP affects Latin American countries, and policymakers have recently attempted to address this issue, particularly in the aftermath of the recent economic crisis. It is essential to measure and evaluate EP to implement strategies and policies effectively. Using a panel quantile regression approach, we investigate the heterogeneous impact of green finance, renewable energy, and energy efficiency (...) on EP for 33 Latin American countries from 2000 to 2018. Furthermore, certain associated control variables are incorporated into our model to avoid an omitted variable bias. According to empirical results, the impact of independent variables on EP is heterogeneous. Specifically, green finance is an essential source of alleviating EP, and it has a significant positive effect across all quantiles, but it is especially strong in the middle quantiles. RE and EE significantly mitigate EP, with the strongest effects occurring at higher quantiles. By including green finance, RE, and EE as the main explanatory determinants of EP, the findings urge policymakers in Latin American countries to design a comprehensive energy conservation policy to minimize the effects of massive EP.

The use of energy from wind has a multi-faceted relationship to visibility. Between 1973 and 1991, various actors in the West German environmental movement made assertions about the visibility of renewable sources of power, but wind energy took on a particular prominence. In this article, the question of how different actors have used knowledge and the materiality of wind turbines for competing purposes is explored. Environmentalists attempted to create visible signs of a valid alternative energy future (...) by tinkering with small, decentralized wind turbines, while the Federal Republic of Germany's Ministry of Research and established energy providers used the failure of the state-subsidized large-scale wind-energy project GROWIAN to criticize renewables and brand their application as misguided. In both cases, actors created new wind energy visibilities to convey their conflicting interests—pitting those advocating a new, environmentally friendly energy system against those who sought consolidation of the large-scale fossil-nuclear energy system.

Certification for biofuels has been developed to ensure that biofuel production methods adhere to social and environmental sustainability standards. As such, requiring biofuel production to be certified has become part of EU policy through the 2009 renewable energy directive, that aims to promote energy security, reduce emissions and promote rural development. According to the EU RED, in 2020 10 % of our transport energy should come from renewable sources, most of which are expected to be (...) biofuels. In this paper I examine what biofuel certificates are, what they can achieve and what their limitations are. Methodologically, I will evaluate them using the standards of instrumental, practical and communicative rationality. With regard to instrumental rationality, I conclude that the EU RED makes an important but unjustified assumption in demanding certified biofuels for its target: that if biofuel production is sustainable, then biofuel use is too. I also argue that, where the EU assumes that biofuel certification is a sufficient means to achieve the EU RED’s goals, it is at best an insufficient means and at worst not a means at all towards achieving these goals. With regard to practical rationality, I argue that more attention needs to be paid to trade-offs between different goals in the EU RED, particularly with regard to providing investor security and not capping transport energy consumption. With regard to communicative rationality, I argue that the policy-making process of the EU RED has been seriously flawed, and that certification development processes also can improve significantly.

Social entrepreneurship increasingly involves collective, voluntary organizing efforts where success depends on generating and sustaining members’ participation. To investigate how such participatory social ventures achieve member engagement in pluralistic institutional settings, we conducted a qualitative, inductive study of German Renewable Energy Source Cooperatives. Our findings show how value tensions emerge from differences in RESCoop members’ relative prioritization of community, environmental, and commercial logics, and how cooperative leaders manage these tensions and sustain member participation through temporal, structural, and collaborative (...) compromise strategies. We unpack the mechanisms by which each strategy enables members to justify organizational decisions that violate their personal value priorities and demonstrate their varying implications for organizational growth. Our findings contribute new insights into the challenges of collective social entrepreneurship, the capacity of hybrid organizing strategies to mitigate value concessions, and the importance of logic combinability as a key dimension of pluralistic institutional settings.

This IEEE Vision for Smart Grid Communications: 2030 and Beyond Roadmap is a high-levelsupplement of the full vision document IEEE Vision for Smart Grid Communications: 2030 andBeyond. Communication is a major enabling technology for the Smart Grid. We believe that the powergrid will tend to utilize advances in communications since the data exchange requirements willscale up for the Smart Grid. Smart Grid communication will help to improve demand forecasting,enable self-healing from power disturbance events, facilitate active participation by consumers in demand-response (...) mechanisms, and provide resilience against physical and cyber attacks. Smart Grid communication will also help to improve quality of power, allow easy integration of renewable energy sources into the grid, foster innovation to enable new products, services, and markets, assist in optimization of assets, and improve operating efficiency.

The bioclimatic architecture is still fascinating to all of us. The lack of energy that the world is facing nowadays is forcing architects and engineers to implement smart solutions benefiting at the maximum from nature itself without considering the primary sources of energy that the world is actually using. Bioclimatic design has the roots in history, despite the fact that little attention has been paid to it throughout history. It is important to understand how natural systems operates, creating (...) closed or semi-closed systems that mirror the ecological systems on Earth. The components of bioclimatic design deal mostly with: climate type and requirements; adaptive thermal comfort; vernacular and contextual solutions; tools and assessment methods; microclimate; sun path; wind; rain; passive and active systems and responsive forms. The aim of the bioclimatic design is to improve the natural environment through the utilization of clean energy and renewable energy system; to reduce the need for energy for heating purposes; and to reduce the energy for cooling proposes, air conditioning and lighting. Furthermore, bioclimatic design involves changes in regulation, improves the house comfort, and also improves urban quality of life. Bioclimatic buildings also include the use of building elements such as walls, windows, roofs, and floors, in order to collect, store, and distribute solar thermal energy and to prevent overheating. The aim is to manage the energy flows providing comfortable conditions during the entire year and the entire day. Minimization of thermal losses and utilization of climatic conditions (climate; microclimate, sunrise) are other important issues to consider. According to many studies, the best orientation for a building in order to maximize the heat gain during winter is east–west and the primary façade should face south. Sustainability is mostly an outcome, rather than a goal or a process. The aim of all designers is to reduce the ecological footprints and to improve the quality of life. The energy sustainability and the use of natural resources must be an integral part of a sustainable development. Nowadays, there are softwares that are developed in order to carry out environmental assessment tools and standards, in order to draw conclusions about internal thermal comfort; uncomfortable times in the building during the entire year; the need for shading devices and their dimensions; energy use, energy cost, etc. Simulations are essential in the design process. Examples chosen as case studies participate to have a better insight into the overall approach of the bioclimatic design. Applying the principles of bioclimatic design remains still a challenge in redefining the perfect bioclimatic house. (shrink)

The article describes how emissions from the nation’s coal-fired power plants create far-reaching problems for people and wildlife, including acid rain; ozone pollution; the deposition of mercury and nitrogen in lakes, streams, and coastal waters; and global climate change. These environmental problems cut across all regions and endanger the entire range of wildlife, from the tiniest invertebrates to top predator mammals, in addition to threatening our health and economy. Moreover, current efforts to address these problems are not sufficient. In this (...) article, the National Wildlife Federation makes a series of recommendations for reducing the toll from coal, including: closing the loophole in the Clean Air Act that allows older power plants to emit significantly more pollution than newer, more efficient ones; toughening restrictions on sulfur dioxide and nitrogen oxides and creating meaningful mercury and carbon dioxide emissions caps; and promoting energy efficiency and renewable energy sources.

This article discusses German and European climate policy, inquiring mainly whether the ambitious goals the EU has set itself can be achieved via the instruments presently employed for the purpose and whether these instruments are efficient. In particular we discuss shortcomings of the European emission trading system, we further level criticism at energy policy measures, notably subsidization for renewable energy sources and the overlap with emissions trading. Further we argue that while 20% reduction of CO2 is feasible (...) at a reasonable cost, derived targets such as a share of 20% of renewable energy and 20% efficiency increase is expensive and not necessary. Finally, we scrutinize the latest climate-protection package proposed by Germany’s environment minister. (shrink)

The realization of dwindling fossil fuel supplies and their adverse environmental impacts has accelerated research and development activities in the domain of renewable energy sources and technologies. Global energy demand is expected to rise during the next few decades, and the majority of today's energy is based on fossil fuels. Alternative energy sources and technologies can play a vital role in lowering or eliminating our reliance on fossil fuels. However, such a transition will require a (...) large investment and will not be reversible. The benefits of hydrogen and other liquid fuels as transportation fuels are not marginal, but the real urgency in greenhouse gas reductions and fossil fuel replacement should not be translated into an energy infrastructure based on unsustainable sources in the long run. It is wise to examine each option thoroughly and objectively now and discard those with little potential so our focus and effort may be placed elsewhere. (shrink)

The strengths and weaknesses of current energy planning can be attributed to the limited economic, social, and environmental contexts taken into account as a result of the current intellectual and professional division of labor. A preventive approach is developed by which the ratio of desired to undesired effects can be substantially improved. It takes into account supply-and demand-side options, renewable and nonrenewable sources, and net energy availability. Alternative energy must be considered within such a strategy, which (...) carefully examines its effects on society and the biosphere. Intellectual barriers are identified, and ways of overcoming them are suggested. (shrink)

Africa's renewable energy resource base is large. Traditional patterns of energy use have resulted in widespread environmental degradation. Renewable energy technologies are capable of harnessing this energy on a sustainable basis. However, despite some notable successes, efforts to disseminate these tech nologies have resulted in numerous failures. The failure of such efforts has been attributed to a variety of problems which have yet to be evaluated in a comprehensive and policy-relevant form. Such analysis is (...) prerequisite to enabling policy-makers to act effectively. (shrink)

The standards of energy and environmental design are improving day by day, are flexible enough, and in continuous change. The designers are the first ones which introduce the inputs into the system in order to improve it. The overall city should be planned as a socio-natural hybrid system. The LEED program has been developed in the US since 1998. It has been adopted in almost 40 countries and it is widely used by public. The LEED standards are based on (...) reducing overall impact rather than on a specific issue or topic, trying to be green as much as possible. The reliance to outside sources (programs and standards) is also important in order to enlarge the expertise area and the variety of subjects. The green city should be well planned and well documented since the early stage of design, reducing the costs and synchronizing the work of different systems that operates within the building. The LEED standards involve the environmental, economic, and social impact, regardless at this point the standards are socially neutral. The city planned according to LEED standards is a socio-neutral hybrid one. On the other hand, BREEAM is established since 1990 in the UK and certifies the sustainability of buildings. For each environmental certification, there exist differences between various criteria related to building energy efficiency. The evaluation of the performance improvement over specified baseline requirements is the common point of the two building standards. The sustainable assessments such as BREEAM or LEED can be applied or adopted in any region of the world. The Albanian case does not adopt any of them. Based on EPC (energy performance certificate), the building is considered to be in compliance with the minimum performance requirements of energy, aiming to achieve optimal levels of energy consumption for a typical use of the building. The building is considered as zero energy building when the ratio of the total energy consumption of the current building per sqm of the surface is equal or be less than 50% and the ratio of renewable energy produced in the building during a year compared to the consumption of total energy of the current building for one sqm of the surface. Expressed as a percentage is equal to or greater than 50%. (shrink)

A new field of biomedical ethics is opening up, concerning what should be done to reduce the direct and indirect impacts of greenhouse gas emissions on human health. Some of these impacts could be described as ‘direct’, in the form of fatalities and illnesses due to the increasingly frequent heatwaves in many countries of recent years, ascribable to anthropogenic climate change. Other impacts are mediated through the air pollution that results from emissions from vehicles in the form of a cocktail (...) of carbon oxides including carbon monoxide, nitrogen dioxide and particulates. Most of the world’s cities have streets with unsafe pollution levels, and one child’s death in Britain has been officially ascribed to air pollution (BBC 2020). This presentation aims to validate the above claims about the impacts of emissions on health, and to suggest remedies. The early phasing out of vehicles powered by internal combustion engines is the ultimate remedy for the latter set of impacts, while the urgent replacement of energy generated from fossil-fuel sources with renewable energy is the best way to remediate the former set. More immediate remedies for air pollution include restricting the use of roads and streets in urbanised areas by vehicles to bicycles and light vehicles with small engines. Medical and nursing education should include the diagnosis and treatment of pulmonary conditions resulting from increased levels of carbon oxides, nitrogen oxides and particulates. Medical and nursing practice should focus on the early identification of vulnerable adults and children at risk from air pollution, and warnings against walking, running or cycling along the most polluted thoroughfares.

There exist overwhelming – and morally compelling – reasons for shifting to renewable energy (RE), because only that will enable us to timely mitigate dangerous global warming. In addition, several other morally weighty reasons speak in favor of the shift: considerable public health benefits, broader environmental benefits, the potential for sustainable and equitable economic development and equitable energy access, and, finally, long-term energy security. Furthermore, it appears that the transition to RE is economically, technologically, and politically (...) feasible at this point in time. However, there are different possible pathways towards that goal, all of which involve tough choices. Some of these concern different ways of living: Do we have to make a choice between being sustainable and maintaining our current living standard? And if so, how can we balance the value of high living standards against that of a sustainable energy regime? In this chapter, I will not conduct a comprehensive analysis of all available renewable energy technologies, but rather provide a number of examples of tough choices entailed by solar, wind and hydropower. I will also attempt to rebut some of the common misconceptions regarding RE technologies. (shrink)

We all know that renewable energies are important for environmental reasons. However, recent developments should open our eyes to the fact that they are even more critical for sustainable development. In this commentary, we argue that societal benefits should be included in renewable energy decisions. Specifically, we discuss their contributions to freedom, peace, and democracy.
