The term sustainable energy is very familiar to all of us, yet its exact definition or meaning has so far been vague. To date, the widely adopted definition of sustainable energy has been inspired by the definition of sustainable development formulated more than 30 years ago in Our Common Future—the UN's Report of the World Commission on Environment and Development. The current definition conceals the true spirit of the report, and this has some ramifications. It raises the question as to whether we have put too much emphasis on attaining the future dimension of sustainability in the middle of a situation where energy survivability is in fact the real issue in many parts of the world. In this paper, the role of energy in sustaining the livelihoods of low-income communities is discussed. The existing definition of sustainable energy that the whole world seems to have embraced is looked at critically and its downsides exposed. The identified pillars of sustainable energy and the associated issues are discussed, and the need for an additional pillar, i.e., affordability, is discussed and called for. This paper will argue that the global definition of sustainable energy seems inappropriate and should be jettisoned, and a more realistic definition should be formulated, adopted, and embraced at the local (i.e., national or regional) level taking into account local attributes and factors. The current push for a transition from the reliance on conventional energy sources to "cleaner" energy sources (generally associated with renewable energy) has further exacerbated the issue of energy affordability that has made the conditions even more dire for so many groups of the world's population. In the midst of this situation, those who push for a rushed energy transition seem to be those who also produce an unsustainably high carbon footprint but who can easily offset their carbon footprint through the 'net-zero' concept.

The current non-renewable energy-based transportation system is getting us places while simultaneously killing us. The global oil and gas markets are the most sizeable - 4677.45 billion-dollar industries - in the world in terms of revenue due to human dependency on fast transportation. In pre-industrial revolution times, the average rate of global temperature increase was 0.13-degrees Fahrenheit. The introduction of fossil fuel-based vehicles has more than doubled those numbers, thus resulting in accelerated global warming. Electrical vehicles have a few challenges of their own that we have discussed in this paper, finding solutions to them are based on Yoichi Hori's paper to make our model more energy efficient. Our model has been validated by researches done in the past, this paper combines the findings of formerly published papers to produce a working model of our current design with proof of concept. To reduce the carbon footprint of coal and fossil fuel-based electricity production, solar energy has been considered to charge the vehicle. It is not only an efficient choice, but it is also economical. It saves the consumer around $1778 annually in fuel cost and 38.5g/km in carbon emissions. Using a wireless charging station solves a major UX design problem, making charging an effortless experience. This method is 88.05% efficient at 31.5A. Supercapacitors have high power densities, therefore, being a good power source for the EV in theory, however, research shows that current supercapacitor technology is unable to perform as a standalone power source. Hence our model combines supercapacitors with conventional batteries to power the EV, additionally a break recovery system stores energy in the supercapacitor. This powers the car's acceleration. Our model priorities the use of materials that can be repurposed hence carbon-based electrodes are used - Graphene is a potential choice as it consists of high energy cycles. [ABSTRACT FROM AUTHOR]

Summary: This paper is concerned with innovative approaches to renewable energy sources computation methodologies, which provide more refined results than the classical alternatives. Such refinements provide additional improvements especially for replacement of fossil energy usages that emit greenhouse gas (GHG) into the atmosphere leading to climate change impact. Current knowledge gap among each renewable energy source calculation is rather missing fundamentals of plausible, rational, and logical explanations for the interpretation of results. In the literature, there are rather complicated and mechanically applicable methodologies, which require input and output measurement data match with missing physical explanations. The view taken in this review paper is to concentrate on quite plausible, logical, rational, and effectively applicable innovative energy calculation methodologies with simplistic fundamentals. For this purpose, a set of renewable energy methodological approaches is revisited with their innovative structures concerning solar, wind, hydro, current, and geothermal energy resources. With the increase in the renewable energy utilizations to combat the undesirable impacts of global warming and climate change, there is a need for better models that will include physical environmental conditions and data properties in the probabilistic, statistical, stochastic, logical, and rational senses leading to refined and more reliable estimations with application examples in the text. Finally, new research directions are also recommended for more refined innovative energy system calculations. [ABSTRACT FROM AUTHOR]

Nowadays the world no longer has a choice to reduce the dependency of non-renewable energy resources, especially in buildings. This type of energy like fossil fuel is responsible for global warming and the climate change phenomenon. The construction industry has to depend on renewable energy to improve environmental impacts while operating the buildings. The most promising technologies for buildings are photovoltaic panels system which converts solar radiation into electricity without harming the environment. PV system is not only used as top-roof panels but also it can play an important role in the exterior building cladding and in curtain wall system as well. Building-integrated PV (BIPV) system has two functions the first is used as a façade cladding and the second is power generation for building operation. This research studies the PV curtain wall as a BIPV system and explains why this system is better than the traditional curtain wall through its environmental performance and initial, and operation costs. Based on the analysed tabulated feasibility study considering energy savings outcome and system cost, PV curtain walls proved technical, environmental and economic viability. The paper's case study in Jeddah- KSA provides a real example of how PV curtain wall application plays a fundamental role in achieving high energy performance standards as well as maximize the financial return of investment.

In a notable change from the position in the past, the Greek government took steps to commit itself to greening the economy and determining policies and actions to boost the utilization of renewable energy. The aim of the paper is, firstly, to present the latest developments on the renewable energy policy in Greece, the current achievements and impediments to the implementation of planned reforms in the accomplishment of its 2020 targets, and the specific policy measures introduced; secondly, to discuss the pace of respective developments in other EU-28 member countries; thirdly, to verify the achievements of the government towards reversing previous bureaucratic, prone-to corruption procedures through a questionnaire survey and stratified interviews with market participants. Research survey results from our survey and interviews conducted in the second semester of 2014 are respectively presented. The majority of respondents expect to see the targets set in the National Renewable Energy Action Plan reached by 2020. The paper and questionnaire survey have been conducted under the auspices of the European research program THALES, aiming to measure various aspects of the shadow economy and the areas of renewable energy trade and finance in Greece.

Energy model, a systematic data-intensive multi-objective framework replicating the energy sector of the country or globe, constitutes of energy resource supply, energy consumption sector-by-sector, energy transformation technologies, greenhouse gas emission and energy pricing. Considering the atypical weather pattern yearly and geographical diversity, the challenges and benefits of designing an energy model have been summarized. The paper has documented the tremendous jeopardy of drastic climate change, energy crisis on the global economy, requirement for transition to low carbon economy and rural electrification which have been impetus for the evolution of legitimate energy model. Special emphasis has been provided on the types of energy models that have been developed and practiced throughout the world followed by a comparative analysis of a few. The requirement to configure a unique energy model in India followed by certain recommendations has been proposed in this paper. [ABSTRACT FROM AUTHOR]

Energy is crucial to economic progress, but the contemporary worldwide population increase that demands greater energy generated from conventional exhaustible resources, an energy price upsurge, and environmental concerns, imperils sustainable economic growth. Nevertheless, switching to renewable energy produced from naturally replenished resources promotes energy security, likewise addressing issues such as global warming and climate change. This paper aims at exploring the influence and causal relation between renewable energy, both overall and by type, and sustainable economic growth of European Union (EU)-28 countries for the period of 2003-2014. We notice that the mean share of renewable energy in the gross final energy consumption is 15%, while the mean share of renewable energy in transport fuel consumption is 3%, which are below the thresholds of 20% and 10%, respectively, as set by the EU Directive 2009/28/EC. By estimating panel data fixed-effects regression models, the results provide support for a positive influence of renewable energy overall, as well as by type, namely biomass, hydropower, geothermal energy, wind power, and solar energy on gross domestic product per capita. However, biomass energy shows the highest influence on economic growth among the rest of renewable energy types. In fact, a 1% increase of the primary production of solid biofuels increases GDP per capita by 0.16%. Besides, cointegrating regressions set on panel fully modified and dynamic ordinary least squares regressions confirm the positive influence related to the primary production of renewable energies on economic growth. A 1% increase in primary production of renewable energies increases GDP per capita by 0.05%-0.06%. However, the results of Granger causality based on panel vector error correction model indicate both in short-run and long-run a unidirectional causal relationship running from sustainable economic growth to the primary production of renewable energies, being supported the conservation hypothesis.

European Commission has set clear targets for 2020 regarding energy and environment policy; these targets include 20% cut in greenhouse gas emissions against the 1990 levels. It is believed that adopted strategy has encouraged the renewable energy applications during the last two decades. Moreover, measurement deviations of carbon dioxide flux occurring in respiration chambers has been seen of a great importance to explain the biochemical parameters affecting the climate change issue. This is attributed on many occasions to chamber design constraints and the way they are coupled with the studied site location. This is illustrated by external disturbances whereby when they happen while gas measurements are taken measurement deviations become more evident. This paper surveys the different soil physical, biological and geotechnical parameters and links them to meteorological ones. Consequently it explores their direct and indirect effects to the produced soil efflux. Furthermore this paper proposes several soil temperature models according to the studied case constraints to see what affects soil efflux production. Moreover a clear understanding of what affects the measurement process was achieved through surveying all the internal and external pressure parameters and how they influence the chamber in relation to time. The conclusion is that respiration chamber designers need to preserve chamber internal temperature and pressure to be equal to the outer atmosphere for the case of stabile external conditions. For the case of unstable external conditions design counter measures are incorporated. Furthermore the appropriate gas sensor needs to be selected professionally with emphasis on the importance of installation location inside the chamber. Likewise soil bacterial type and soil temperature also has an influence on efflux production. [ABSTRACT FROM AUTHOR]

Global warming, climate change, and resource depletion have forced us to reconsider energy usage and efficiencies over the last few decades. Residential and commercial buildings are both large energy consumers, so improving energy and material usage efficiency in this sector is a common research topic. According to a recent study, the Building Sector (BS) accounts for 40% of greenhouse gas emissions. The primary objective of this paper is to examine and assess the potential of Renewable Energy Systems (RES) and their combinations for enhancing energy efficiency in the BS. Specifically, the focus will be on converting low energy-efficient buildings into highly efficient ones. The potential of the RES and their combinations for the BS is evaluated based on payback durations, energy generation, and reduction of CO 2 emissions. The optimization flow charts for the RES, feasibility studies, commercialization road maps of energy storage systems and the necessity of control mechanisms for enhancing RES efficiency were discussed. Additionally, the technology drawbacks are discussed, along with various innovative techniques recommended to direct future study in this area. Finally, this article assists the audience clear idea in the selection of the right combination of potential RES based on different conditions to achieve deep decarbonization in BSs. • Buildings sector (BS) responsible for 40% of GHG emissions. • Study assesses potential of Renewable Energy System (RES) in BS. • RES evaluated on payback, energy generation, and CO 2 reduction. • Optimization, feasibility and commercialization studies were discussed. • Article recommends right RES combinations for deep decarbonization in BS.

Today, there is a broad international consensus on the need to ensure carbon neutrality and, more broadly, to address global environmental issues. By promoting increasingly stringent ecological standards and climate regulations in the energy sector and consistently forcing others to emulate its example, the European Union seeks to present itself as a normative power in this area. At the same time, the EU leaders face the need to mobilize public support for the idea of the sustainable climate-oriented transition in order to mitigate its negative economic and social effects. This, in turn, requires the construction and promotion of the compelling and unambiguous energy transition narrative designed to legitimize the EU’s environmental and energy policy. This paper identifies and examines the key elements of such a narrative propagated within the European Union, as well as assesses its perception by various groups of the European countries’ population. The author also outlines a few alternative ‘greentransition’ narratives, which have arisen as a reaction to both the deficiencies of the EU’s energy policy and the challenges posed by the Ukrainian crisis. The author concludes that the EU leaders and the non-governmental and non-profit actors backing them have managed to build a broad and solid public consensus around the official narrative of the energy transition. Under these conditions, one of the central objectives facing the EU leaders is to maintain and strengthen the attained level of public support for its policies, given new transition-related challenges to the territorial integrity and political cohesion of the union. The latter include high inflation rates and the general rise in the cost of living, negative tendencies in the labor market due to its structural transformation, as well as the growing economic heterogeneity of the member states.

Climate change and global warming have increased the awareness of mankind in protecting the world. Wind energy is a favorable alternative to conventional fuels for providing clean and cheap energy. For efficient design of wind station project, the best wind turbine selection plays a noteworthy role in the all life cycle. In this paper, AHP method is utilized on the decision of selection for the best wind turbine among turbine brands for 1.5 MW. The selection of the best turbine from several of different turbine brands is complicated task since a few decision criteria need to be noted simultaneously. In this study, the selected turbines are investigated in detail. Based on the experts’ opinions, the obtained results by this way are evaluated from technical, economic, environmental and customer attributes by AHP. [ABSTRACT FROM AUTHOR]

This article aims to investigate how climate aid devoted to renewable energy contributes to CO2 emissions in recipient countries. Indeed, since the beginning of the 2000s, international agreements between developed and developing countries have promoted the provision of financial aid to the second group of countries to help them fight global warming. We first discuss stylized facts on climate finance devoted to renewable energy and its impact on CO2 emissions. We can see that while the first variable is quickly increasing, the second variable displays a decrease from 2010. Econometric results show that climate aid for renewable energy has a slight impact on CO2 emissions reduction, especially after a threshold. However, despite this optimistic result, the impact is transitory. Indeed, this result can be explained by the fact that developing countries are more preoccupied by economic efficiency than ecological efficiency. However, in countries where a carbon tax is set, the tax contributes to reducing CO2 emissions. Finally, we show that ecological technologies imported through foreign direct investment do not yet play a significant role in reducing CO2 emissions or CO2 intensity. [ABSTRACT FROM AUTHOR]

Anthropogenic global climate change has large and mounting negative economic impacts. Companies and nations responsible for greenhouse gas (GHG) emissions are thus acquiring considerable potential liabilities. If litigation becomes widespread, renewable energy technologies (RETs) potentially offer emitters reduced liability for climate change. This benefit has been ignored because of the lack of knowledge of potential liabilities. To overcome this information deficit, this paper reviews recent literature on the potential for climate change litigation and methods to quantify liability for climate change. Next, the top 10 emitters in the U.S. are identified and their potential liability is quantified using standard GHG emission costs. Potential liabilities are explored in depth with a single case study company comparing the results of the fractional liability from only natural disasters within the U.S. for a single year to a sensitivity of the future costs of carbon emissions from other sources of emission-related liability. Then classes of potential climate change litigants are identified and their capacity to bring such lawsuits is evaluated. The results show that the net income available to shareholders of large companies could see a significant reduction from the emissions liability related to only natural disasters in the U.S. from a single coal-fired power plant. Finally, a rough estimate of the economic risk associated with future scenarios and existing organized international potential litigants is quantified. The results show that potential liability for climate change for the Alliance of Small Island States is over $570 trillion. It is concluded that as emitters begin to be held liable for damages resulting from GHG emissions resulting in climate change, a high value for liability mitigation would provide additional powerful incentives for deployment of renewable energy technologies.

Landfills all around the world are one of the major sources that contribute towards global warming and climate change. Although landfilling should be prioritized last in the waste management hierarchy due to highest greenhouse gas emissions as compared to other waste management systems it is still very common around the world. In this study, methane emissions are estimated by applying First Order Decay model to landfills in Pakistan over the latest data available by Pakistan Environmental Protection Agency. Results demonstrate that nearly 14.18 Gg of methane is emitted from the landfills in Pakistan each year. By combusting this methane in the form of biogas collected from the landfills as a waste management scheme we can reduce greenhouse effect up to ~88%. Same percentage is observed when we apply the similar analysis over the potentially improved practice. Also, Pakistan is facing severe economic crises due to continuous increasing gap between energy demand and supply. Demand is increasing exponentially while supply is observed to remain constant over the last few years due to frozen capacity in spite of having significant renewable/alternate energy resources. Current electricity shortfall has reached up to 6000 MW. Present operational landfills in Pakistan can only contribute up to ~0.1% to cater the total deficit which does not make any significant difference but if 75% of the total waste generated today is collected and 50% of it landfilled then Pakistan has the potential to produce ~83.17 MW of power that can contribute up to 1.4% to overcome the current power shortage. The outcomes of this paper may also be applicable to other developing countries having similar resources. [ABSTRACT FROM AUTHOR]

One of the topics receiving much attention in recent years is climate change and the potential of its integration in impact assessment, both in terms of achieving mitigation and adaptation. Renewable energy projects are part of the efforts to mitigate climate change, replacing the use of fossil fuel with CO2-neutral energy sources. A variety of these projects are subject to environmental impact assessment (EIA), which raises the following questions: What role does an impact assessment play? When is the project environmentally friendly? How are climate change-related impacts assessed in projects with inherent positive effects on climate change? This paper reviews practice, and takes up these questions based on a document study of 19 EIA reports of renewable energy projects in Denmark. The results show that climate change mitigation is included in 18 of the EIA reports reviewed, while adaptation is absent. Also, the results show an emphasis on positive impacts in the reports, and in a few cases discussions of enhancements. Identification and assessment of negative climate change impacts are less apparent. This leads to a discussion of the results in the light of the purpose of EIA. [ABSTRACT FROM AUTHOR]

Environmental issues linked to climate change and global warming have been at the center stage of discussion all over the world. This is due to their magnitude and a broader scope of consequences. The catastrophic effects of greenhouse gases (GHGs) such as CO2, CO, water vapor, and ozone, coupled with other artificially induced chemicals like CFCs have shifted weather patterns across the globe, thereby threatening the environment unpleasantly. In Nigeria, the unprecedented utilization of fossil-based fuels as the main energy source for electricity, transportation, industrial, agricultural, and domestic purposes is one of the contributory factors of climate change. As a result, air pollution, land spills by oil, and increasing heatwaves negatively impacted the ecosystem by intimidating the environment, counteracting biodiversity, decelerating the economy, and provoking human comfort while simultaneously antagonizing socio-economic growth and sustainable development. Recently, the abrupt seizure of rainfall in northern Nigeria left many farmlands burning while many other places where been wiped out by heavy flooding. These scenarios have heightened food shortage, economic hardship and rendered thousands homeless. Thus, the government needs to intensify the campaign for afforestation by planting many trees to support green conservation of biodiversity and unleash the huge potentials of renewable energy resources in the country, as the plausible options to remediate the lingering energy failure and ravaging effects of climate changes. Therefore, this short review of communications X-rayed some recent devasting incidences caused by climate change, its impacts on various sectors, and the need to explore renewable energy resources in the country.

• Future global challenges can mainly be traced back to global population growth and increasing urbanization rates. • Floating Infrastructure is a multifaceted approach to address issues related to climate change and land scarcity. • Offshore energy generation and aquaculture offer higher efficiency and lower emissions than land based alternatives. • Floating construction provides more flexibility and higher resilience for urban development. In the coming decades humanity will be confronted with a number of complex challenges affecting the prosperity and livelihood of billions of people around the globe. The root of these challenges lies in the downright explosion in global population over the last decades combined with a staggering increase of urbanization rates leading to an unprecedented level of demand for food, water, materials and space. Consequently, growing scarcity of essential resources are an ever increasing threat towards global peace and stability. This conflict potential is exacerbated by global warming and the associated sea level rise, which can once again be traced back to the rapidly growing demand for energy and food of the world's economies. In this paper we develop a comprehensive chain of cause and effect surrounding these global developments. Furthermore, we discuss how floating infrastructure, through its application to renewable energy generation, food production, flood protection and even urban expansion, is capable of decoupling multiple linkages in the chain, thus presenting itself as a promising mid- to long-term strategy for addressing these global challenges.

Entering the third millennium food and energy crisis is becoming more serious in line with water scarcity amid of climate change induced by global warming, that so called as FEWS (food energy and water scarcity). In the last five decades Indonesian agricultural development of food crops had been emphasized on cereals and grains based. Conversion of forest into agricultural field in the form of upland and lowland facilitated by irrigation is prioritized for cereals such as rice, maize as well as grain legumes such as soybean, peanut etc. Unfortunately, root crops which their main yield underground are neglected. At the end of second millennium Indonesia was seriously suffered from multi-crisis economic trap, so Indonesia as part of countries under World Food Program to import the huge of food to cover domestic consumption such as rice, wheat, soybean, corn etc. On the other hand, consumption of energy was also increase significantly. These conditions triggering government to stimulate integrated agricultural enterprises for providing abundance of food as well as adequate renewable energy. Although root crops were neglected previously, however from its biological potential to produce biomass promotes root crops into an appropriate position. The variability of root crops which ecologically can be grown from upland in dry areas till swampy submergence condition. Forest conversion into agricultural land is not allowed due to forest is useful to prevent global warming. Therefore, food, feed and fuel (renewable energy) production have to be able grown under agro-forestry. Fortunately the potential of root crops has competency to meet the current need to fulfil food, feed and fuel as well as fibre under future greener environment. [ABSTRACT FROM AUTHOR]

Climate change and global warming have triggered a global increase in the use of renewable energy for various purposes. In recent years, the photovoltaic (PV)-system has become one of the most popular renewable energy technologies that captures solar energy for different applications. Despite its popularity, its adoption is still facing enormous challenges, especially in developing countries. Experience from research and practice has revealed that installed PV-systems significantly underperform. This has been one of the major barriers to PV-system adoption, yet it has received very little attention. The poor performance of installed PV-systems means they do not generate the required electric energy output they have been designed to produce. Performance assessment parameters such as performance yields and performance ratio (PR) help to provide mathematical accounts of the expected energy output of PV-systems. Many reasons have been advanced for the disparity in the performance of PV-systems. This study aims to analyze the factors that affect the performance of installed PV-systems, such as geographical location, solar irradiance, dust, and shading. Other factors such as multiplicity of PV-system components in the market and the complexity of the permutations of these components, their types, efficiencies, and their different performance indicators are poorly understood, thus making it difficult to optimize the efficiency of the system as a whole. Furthermore, mathematical computations are presented to prove that the different design methods often used for the design of PV-systems lead to results with significant differences due to different assumptions often made early on. The methods for the design of PV-systems are critically appraised. There is a paucity of literature about the different methods of designing PV-systems, their disparities, and the outcomes of each method. The rationale behind this review is to analyze the variations in designs and offer far-reaching recommendations for future studies so that researchers can come up with more standardized design approaches.

In this study, we developed a new hybrid mathematical model that combines wind-speed range with the log law to derive the wind energy potential for wind-generated hydrogen production in Pakistan. In addition, we electrolyzed wind-generated power in order to assess the generation capacity of wind-generated renewable hydrogen. The advantage of the Weibull model is that it more accurately reflects power generation potential (i.e., the capacity factor). When applied to selected sites, we have found commercially viable hydrogen production capacity in all locations. All sites considered had the potential to produce an excess amount of wind-generated renewable hydrogen. If the total national capacity of wind-generated was used, Pakistan could conceivably produce 51,917,000.39 kg per day of renewable hydrogen. Based on our results, we suggest that cars and other forms of transport could be fueled with hydrogen to conserve oil and gas resources, which can reduce the energy shortfall and contribute to the fight against climate change and global warming. Also, hydrogen could be used to supplement urban energy needs (e.g., for Sindh province Pakistan), again reducing energy shortage effects and supporting green city programs. [ABSTRACT FROM AUTHOR]
