"This paper presents a futures study of international forest trends. The study, produced as part of the Swedish Future Forest program, focuses on global changes of importance for future Swedish forest use. It is based on previous international research, policy documents, and 24 interviews with selected key experts and/or actors related to the forest sector, and its findings will provide a basis for future research priorities. The forest sector, here defined as the economic, social, and cultural contributions to life and human welfare derived from forest and forest-based activities, faces major change. Four areas stand out as particularly important: changing energy systems, emerging international climate policies, changing governance systems, and shifting global land use systems. We argue that global developments are, and will be, important for future Swedish forest use. The forest sector is in transition and forest-, energy, climate- and global land use issues are likely to become increasingly intertwined. Therefore, the 'forest sector' must be disembedded and approached as an open system in interplay with other systems."

3. Sustainable Energy: Concept and Definition in the Context of the Energy Transition—A Critical Review.

Halawa, Edward
- Abstract
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]

Against an academic and policy backdrop of interest in (and concerns about) the issue, this paper draws on a range of academic writing in various disciplines to explore visual strategies of climate change communication. The geographic scope of the investigation is the United Kingdom, with particular attention to recognizable icons of climate change in UK media and the images used in political campaigns. The paper is in two parts. The first part concentrates on various efforts to put a 'face' on the climate change issue, while part two suggests that weather and renewable energy are the dominant alternative motifs. The paper draws a basic distinction between fear-laden representations of climate change and a variety of visual efforts to use so-called inspirational imagery. All of the images reviewed suggest an affirmative answer to the question in the title, there are multiple efforts underway to move beyond polar bears and represent climate change in more creative and meaningful ways. The bigger question addressed is one raised already by photographers as well as academics, i.e. whether documentary photography (rather than particular types of images) is the more fundamental issue. The answer in the paper is that photographs are no different from other visual images in their capacity to draw attention to messages. The challenge is to use visuals creatively, in ways that prompt positive engagement with climate change without enhancing public disengagement and fatalism.

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.

A recent study conducted by researchers at Swansea University in the United Kingdom explores the interlinkages between carbon risk and the volatility of the renewable energy sector. The study utilizes a time-varying parameter vector autoregression (TVP-VAR) and an extended joint connectedness approach to analyze these connections. The findings indicate that the COVID-19 crisis led to a peak in system-wide dynamic connectedness in early 2020. The research suggests that these findings can inform policy decisions to mitigate rapid fluctuations in carbon prices, protect against systemic financial risks in the renewable energy sector, and ensure a stable green energy supply.

Purpose – The aim of the paper is to examine the renewable energy resources for enhancing a green energy development in the face of energy crisis and climate change, and to explore the prospects for "new" renewable energy sources and the green energy initiatives taken in the Pacific Island countries (PICs). Design/methodology/approach – The data were collated from a wide variety of sources including policy documents, road maps, reports, research articles on renewable and green energy sources. The methodology adopted was primarily a qualitative one based on a "content analysis". Findings – The findings reveal that increasing emphases have been given recently to "new" renewable and green energy sources in the Pacific Island countries as mitigation and adaptation strategies to fuel crisis and climate change. PICs have taken a wide range of green energy initiatives including "biomass", solar, wind and other non-traditional renewable energy sources and bio-fuels development. Prospects for coconut, copra and palm-oil based bio-fuels do exist in many PICs. Opportunities for ethanol bio-fuels also exist especially in Fiji. Practical implications – Renewable and green energy sources are of practical implications to PICs. There is, however, a greater need for framing sound energy policies by the PICs. Originality/value – The author has brought out clear linkages between climate change and green energy development and analyzed the importance of new renewable energy sources, especially in PICs. The paper has higher policy relevance and it is of great value in the context of sustainable energy development in PICs. [ABSTRACT FROM AUTHOR]

Purpose - The purpose of this investigation is the modeling of rapid climate changes (RCC) and analysis of their impacts in ecological and economic systems, in particular, their responses on the rate of RCC and assessment of the considered factors most influenced by RCC. Design/methodology/approach - For modeling impacts of the RCC, the model WORLD3 has been used. Since it is expected that the greatest impacts of RCC be in energy, in this case, the WORLD3 model has been used under the assumption that RCC influences the rapid decrease of energy during a time period of one year. Therefore, the results will be more explicit than in the case when the change occurs gradually during a longer time period. Findings - The results obtained in this work show that increasing the rate of RCC can be associated also with nonlinear responses of economic and ecological factors. It is seen from the analysis that the later the RCC occurs in the time scale considered, the lesser the consequences for ecological and economic systems affected by the RCC. Practical implications - From these results, it can be concluded that adaptability and resilience of ecosystems and economies is needed, especially for the factors that are most affected by RCC - in this case~ the population and energy, exert efforts for reducing the causes of RCC, and prompt action to mitigate global warming as the main cause of RCC. Also, these results show the possibility of early development of potential mitigation and adaptation strategies and allow for a better evaluation of risk exposure. Originality/value - This work is original, as no such analysis has been carried out about impacts of RCC in economic and ecological systems. The paper provides data and results upon which further research could be carried out. [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]

Energy is the most important commodity for a modern society. Therefore, energy is a key ingredient in all sectors of modern economies, and it is a sign of power of a country. In fact, the development of a country is depending on the energy consumption per capita. The conversion of energy from one form to another (e.g. heat to electricity) often affects the environment in many ways, thus the study of energy is not complete without considering its impact on the environment Fossil fuels such as coal, oil, and natural gas have been used as the source of energy for centuries. These fossil fuels, however, have adverse effects on environment, namely air pollution, global warming and climate changes. Nowadays, the environmental pollution has reached such high levels that it became a serious threat to plants, wild life, and human health. Air pollution affects the ozone layer, the oxygen and carbon dioxide cycles. The other serious pollutant in air is carbon monoxide. It is more hazardous than carbon dioxide because it can bind with the red blood cells of the human and affects human organs, especially the brain. Fossil fuels are mixture of various chemicals, and can carry sulfur and nitrogen compounds as well. These sulfur and nitrogen compounds upon burning produce SO2 and NOx which are severe air pollutants. SO2 and NOx can be converted to sulfuric acid (H2SO4) and nitric acid (HNO3), respectively, which results in risky acid rains. Intense research is ongoing on the renewable energy sources (such as solar, wind, hydro, biomass, geothermal, wave, tide, etc.) to minimize fossil fuel consumption. In this paper, adverse effects of fossil fuels on the environmental pollution and the greenhouse effects will be discussed in detail along with hydrogen usage in fuel cells. [ABSTRACT FROM AUTHOR]

Abstract: Over the last two decades; technical, economic and environmental benefits of hydroelectric power make it an important contributor to the future world energy mix, particularly in the developing countries. Turkey has a total gross hydropower potential of 433GWh/yr, but only 125GWh/yr of the total hydroelectric potential of Turkey can be economically used. By the commissioning of new hydropower plants, which are under construction, 36% of the economically usable potential of the country would be tapped. Turkey''s total economically usable small hydropower potential is 3.75GWh/yr. It is expected that the demand for electric energy in Turkey will be about 580 billion kWh by the year 2020. Turkey is heavily dependent on expensive imported energy sources that place a big burden on the economy and air pollution is becoming a great environmental concern in the country. In this regard, renewable energy resources appear to be the one of the most efficient and effective solutions for clean and sustainable energy development in Turkey. Environmentally friendly energy development has enormous implications for developing countries as major emitters due to their rapid economic and population growth. With some possible options, the paper concludes that the reduction of emissions can only be achieved when policies are supportive and well targeted, standards and incentives are realistic and flexible, and the public is actively responsive to environmental degradation. Turkey''s high rate of energy-related carbon emissions growth is expected to accelerate, with emissions climbing from 57 million tons in 2000 to almost 210 million tons in 2020. Carbon intensity in Turkey is higher than the western developed nation average. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions for clean and sustainable energy development in Turkey. This paper deals with Turkey''s renewables energy sources for sustainable environment. [Copyright &y& Elsevier]

The most stringent emission scenarios published by the Intergovernmental Panel on Climate Change (IPCC) would result in the stabilization of atmospheric carbon dioxide (CO
2 ) at concentrations of approximately 550 ppm which would produce a global temperature increase of at least 2°C by 2100. Given the large uncertainties regarding the potential risks associated with this degree of global warming, it would be more prudent to stabilize atmospheric CO2 concentrations at or below current levels which, in turn, would require more than 20-fold reduction (i.e.,≥95%) in per capita carbon emissions in industrialized nations within the next 50–100 years. Using the Kaya equation as a conceptual framework, this paper examines whether CO2 mitigation approaches such as energy efficiency improvements, carbon sequestration, and the development of carbon-free energy sources would be sufficient to bring about the required reduction in per capita carbon emissions without creating unforeseen negative impacts elsewhere. In terms of energy efficiency, large improvements (≥5-fold) are in principle possible through aggressive investments in R&D and the removal of market imperfections such as corporate subsidies. However, energy efficiency improvements per se will not result in a reduction in carbon emissions if, as predicted by the IPCC, the size of the global economy expands 12-26-fold by 2100. Terrestrial carbon sequestration via reforestation and improved agricultural soil management has many environmental advantages, but has only limited CO2 mitigation potential because the global terrestrial carbon sink (ca. 200 Gt C) is small relative to the size of fossil fuel deposits (≥4000 Gt C). By contrast, very large amounts of CO2 can potentially be removed from the atmosphere via sequestration in geologic formations and oceans, but carbon storage is not permanent and is likely to create many unpredictable environmental consequences. Renewable energy can in theory provide large amounts of carbon-free power. However, biomass and hydroelectric energy can only be marginally expanded, and large-scale solar energy installations (i.e., wind, photovoltaics, and direct thermal) are likely to have significant negative environmental impacts. Expansion of nuclear energy is highly unlikely due to concerns over reactor safety, radioactive waste management, weapons proliferation, and cost. In view of the serious limitations and liabilities of many proposed CO2 mitigation approaches, it appears that there remain only few no-regrets options such as drastic energy efficiency improvements, extensive terrestrial carbon sequestration, and cautious expansion of renewable energy generation. These promising CO2 mitigation technologies have the potential to bring about the required 20-fold reduction in per capita carbon emission only if population and economic growth are halted without delay. Therefore, addressing the problem of global warming requires not only technological research and development but also a reexamination of core values that equate material consumption and economic growth with happiness and wellbeing.

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]

Comparative and uniform law. Jurisprudence ,K1-7720 - Abstract
Ecosystems services include the collection, concentration, and storage of solar energy as fossil fuels (e.g., coal, petroleum, and natural gas). These concentrated forms of energy were produced by ancient ecosystem services. However, our legal and economic systems fail to recognise the value of the ecosystem service subsidies embedded in fossil fuels. This ecosystem services price subsidy causes overuse and waste of fossil fuels in the free market: fossil fuels are consumed more quickly than they can be replaced by ecosystem services and in far larger quantities than they would be if the price of fossil fuels included the cost of solar energy collection, concentration and manufacturing of raw fossil fuels. Moreover, burning fossil fuels produces enormous environmental, human health and welfare costs and damage. Virtually no legal literature on ecosystem services, sustainable development, or sustainable energy, considers fossil fuels in this context. Without understanding stored energy as an ecosystem service, we cannot reasonably expect to manage our fossil fuel energy resources sustainably. International and domestic energy law and policy systems generally ignore this feature of fossil fuel energy, a blind spot that explains why reducing greenhouse gas emissions from fossil fuels is fundamentally a political challenge. This paper will use new understandings emerging from the field of complex systems to critique existing legal decision-making models that do not adequately account for energy ecosystem services in policy design, resource allocation and project approvals. The paper proposes a new "least-social-cost" decision-making legal structure that includes ecosystem energy services.

The main part of mankind’s ecological footprint is the carbon footprint, a measure of the environmental impact of humanity’s energy release from fossil fuels. The use of fossil fuels will have to change in the forthcoming decades to a largely climate-neutral use of solar energy enabled by dramatic cost reductions for PV and wind energy systems. The impact of this trend on world society has been discussed in a previous paper. In connection with these important technical developments, the role of electricity, its transport and storage will alter in the coming decades, allowing the design and use of larger and larger electricity grids and a parallel use of hydrogen for both storage and energy transport. This will further change the energy landscape of the world. All these developments and their relationship to global sustainable development are elaborated in this cross-disciplinary paper by specifically analyzing whether the Sustainable Development Goals by the United Nations are an effective road map for humanity to handle global climate change risks.

This article aims to investigate how climate aid devoted to renewable energy contributes to CO
2 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.

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.

This paper aims at explaining the universality and broadness of the research in energy studies. Specifically, it wants to show that the energy research is not a solely engineering or natural sciences field and how it can be done in social sciences. The paper draws some relevant examples including energy research in literature and poetry, history, religion, art, as well in other social sciences and humanities. In general, it becomes apparent that energy research can boast vast depths and angles that are worth exploring for any social scientist. Given the key importance of energy research in the third decade of the 21st century and the worldwide focus on the renewable energy sources, electrification of transport and heating in the face of the threatening global warming and climate change, it seems relevant to focus on researching the perspectives and paradigms for the traditional and renewable energy sources in the 21st century using the toolbox of the social sciences.

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]

ENVIRONMENTAL impact analysis , *CLIMATE change , *RENEWABLE energy sources , *GLOBAL warming , *ENVIRONMENTAL degradation - Abstract
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]

This paper is aimed at the call of the United Nations Intergovernmental Panel on Climate Change (IPCC) for the need to maintain global warming within a controllable range. The goal is to target carbon emissions to achieve &ldquo, net-zero&rdquo, emissions, along with constructing a green energy investment strategy model for firms in response to government&rsquo, s environmental protection policies. The paper uses the real options approach of dynamic investment decision to construct an investment decision model. Considerations include government taxation of carbon emissions, subsidies to reduce carbon emission policies, and incentives for firms to renew their investments in green energy equipment. Assuming that there is uncertainty in government carbon emission taxes and a reduction of carbon emission subsidies, the changes follow the joint geometric Brownian movement. We used this model to solve the optimum of the threshold for carbon emission taxes and of carbon emission reduction subsidies ratio. If carbon emission taxes and carbon emission reduction subsidies ratio are higher than the threshold, a firm suspends investment in green energy equipment because government subsidies are insufficient. If carbon emission taxes and the carbon emission reduction-subsidy ratio are less than or equal to the threshold, then a firm is qualified for the government&rsquo, s subsidies for reducing carbon emissions, and the firm invests in green energy equipment. The results of this study can provide reference for firms to invest in green energy equipment, and for government control of carbon emission policies. This policy can effectively reduce carbon emissions and achieve co-construction, co-governance, and the sharing of innovative social governance patterns. Finally, it can create a win&ndash, win situation between the government, firms, and society.

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.

Abstract: The outcome of COP15, the conference on climate change in Copenhagen, was the Copenhagen Accord which was recognised by the 193 countries that attended. The Accord set no compulsory limits on carbon emissions, and none of the countries that introduced it – USA, China, India [with Brazil and South Africa] – has signed the Annexe to the Kyoto Agreement, committing them to limit their emissions. Climate change is only of secondary importance to them compared with eradicating poverty. Nevertheless three of these countries are in the lead currently for installing renewables, far ahead of most of those [only 37 out of 187 countries world-wide] who are committed to limiting their emissions. This paper explains why. The main function of renewable energy is to save fuel, thereby reducing energy imports and maintaining security of energy supplies without the need to fight world wars over them. Also, being capital intensive with all the money paid up-front, renewables avoid the price fluctuations that bedevil the oil and other fossil fuel industries. As capacity is doubling every 3 years, renewables prices will come down with savings of scale, so wind power in particular will soon be the cheapest form of power. [Copyright &y& Elsevier]

Abstract: Given the recent increasing public focus on climate change issues, there is a need for robust, sustainable and climate friendly power transmission and distribution systems that are intelligent, reliable, and green. Current power systems create environmental impacts as well as contributing to global warming due to their utilization of fossil fuels, especially coal, as carbon dioxide is emitted into the atmosphere. In contrast to fossil fuels, renewable energy is starting to be used as the panacea for solving climate change or global warming problems. This paper describes a feasibility study undertaken to investigate the potentialities of renewable energy including the prospective locations in Australia for renewable energy generation, in particular solar and wind energy. Initially, a hybrid model has been developed to investigate the prospects of wind energy for typical Australian region considering production cost, cost of energy, emission production and contribution from renewable energy using the Hybrid Optimization Model for Electric Renewable (HOMER), a computer model developed by the USA’s National Renewable Energy Laboratory (NREL). This model also explores suitable places around Australia for wind energy generation using statistical analysis. Subsequently, the usefulness of solar energy in the Australian context and suitable locations for solar energy generation are also investigated using a similar hybrid model. Finally, the model has been developed to investigate the prospects of renewable energy in particular wind and solar energy including specific locations in Australia that would be suitable for both wind and solar energy generation. From simulation analysis it is clearly observed that Australia has enormous potentialities for substantially increased use of renewable energy; a large penetration of renewable energy sources into the national power system would reduce CO2 emissions significantly, contributing to the reduction of global warming.

Abstract: For all but the last 250 years, mankind was almost entirely dependent on renewable energy, mainly from biomass and wind. Then the era of fossil fuels downed and we shifted away from renewables. But excessive use of fossil fuel has now precipitated existence-threatening climate change and ocean acidification. So the world is once again reverting to renewables in a big way. It is as if the human quest for energy has come full circle. But will this ‘home coming’ bail us out of the global environmental crisis? This paper says it will not as long as we do not drastically reduce the largely conspicuous and wasteful consumption.

Abstract: Climate change, global warming and the increasing in oil price are issues that concern everyone lately. Renewable energy is the solution for a safe and efficient environment for the new generations. Renewable energy sources are sustainable and are zero carbon emission. In order to deploy these sources efficiently, expertise in this field must be provided. This is accomplished by educating the young generations to all related issues regarding these sources and the related technologies. This paper describes the experience of introducing renewable energy in the curriculum for undergraduate students in the United Arab Emirates (UAE) and the steps taken to enhance the learning process. It only represents the first stage of implementing green energy education into an engineering technology program and highlights the impact of this experience on the students with respect to the environment and the community. Such experience is an example that can be followed in order to promote renewable energy technologies and to develop the expertise in this field in a country that has just started to embrace renewable energy.

• 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.

Global trajectories for reducing carbon emissions depend on the local adoption of alternatives to conventional energy sources, technologies, and urban development. Yet, decisions on which type of capital investments to make, made by local governments as part of the normal budget cycle, typically do not incorporate climate considerations. Furthermore, current academic and professional literature specific to climate change draws attention to decision-making tools that would require access to technical expertise, data, and financial support that may not be practical for cities in low- and middle-income countries. Arguably, the methodologies most able to effect this transformation will be those that are convenient and affordable to administer, and that offer straight-forward low carbon alternatives to traditional forms of infrastructure investment. Current methodologies for capital investment planning that do not take climate change into consideration can result in prioritization of investments that diverge from a low carbon path and a potential missed opportunity to reap financial benefits from efficiency gains. This paper concludes that relatively minor alterations to common procedures can reveal the trade-offs and local benefits of low carbon alternatives in the capital investment planning process. This paper was written as an input to the preparation of the Climate-Informed Capital Investment Planning Guidebook, a how-to guide for local government staff, which will be published in 2015.

To maintain global warming below 1.5 °C this century, as the Paris Agreement aspires, the annual greenhouse gas emissions must be cut in half within the next eight years. [Extracted from the article]

A variety of energy sources will compete to provide the energy services that humans will require over the next 100 years. The balance of these sources will depend upon the availability of fossil fuels and the development of new technologies including renewable energy technologies, and will be one of the keys in projecting greenhouse gas emissions. There is uncertainty about each of the energy sources. With oil, for example, there are two alternate views of future reserves, one that reserves are geologically limited and that supplies will declinewithin a decade or two, the other that there are enormous quantitiesof hydrocarbon in the earth`s crust and that reserves are a functionof developing technology and price. With solar voltaics, as a secondexample, there is optimism that the technology will become increasingly competitive, but there is uncertainty about the rate at which costs can come down and about ultimate cost levels. This paper reviews the reserves of fossil fuels and the prospects for nuclear power and the renewables. It also reviews the main energy conversion technologies that are available now or are expected to become increasingly available through time. However, it should be noted that, over a time horizon of 100 years, there may be quite radical changes in both production and conversion technologies that cannot be predicted and it is quite possible for some as yet unheard of technology to be developed andto transform the markets. The paper has been written to aid the development of new scenarios for the emission of greenhouse gases for theIntergovernmental Panel on Climate Change. [ABSTRACT FROM AUTHOR]

Ecosystems services include the collection, concentration, and storage of solar energy as fossil fuels (e.g., coal, petroleum, and natural gas). These concentrated forms of energy were produced by ancient ecosystem services. However, our legal and economic systems fail to recognise the value of the ecosystem service subsidies embedded in fossil fuels. This ecosystem services price subsidy causes overuse and waste of fossil fuels in the free market: fossil fuels are consumed more quickly than they can be replaced by ecosystem services and in far larger quantities than they would be if the price of fossil fuels included the cost of solar energy collection, concentration and manufacturing of raw fossil fuels. Moreover, burning fossil fuels produces enormous environmental, human health and welfare costs and damage. Virtually no legal literature on ecosystem services, sustainable development, or sustainable energy, considers fossil fuels in this context. Without understanding stored energy as an ecosystem service, we cannot reasonably expect to manage our fossil fuel energy resources sustainably. International and domestic energy law and policy systems generally ignore this feature of fossil fuel energy, a blind spot that explains why reducing greenhouse gas emissions from fossil fuels is fundamentally a political challenge. This paper will use new understandings emerging from the field of complex systems to critique existing legal decision-making models that do not adequately account for energy ecosystem services in policy design, resource allocation and project approvals. The paper proposes a new "least-social-cost" decision-making legal structure that includes ecosystem energy services.
