Turkey’s rapid economic growth followed by increasing gap between domestic energy production and consumption signifies the large-scale integration of low-carbon and renewable resources into energy system. Turkey’s energy demand is increasing and supplying fossil energies such as oil and gas is becoming more challenging due to the lack of domestic hydrocarbon resources. The country is facing two main issues; first, maintaining energy balance and second, handling environmental issues. Nevertheless, Turkey has substantial renewable and low-carbon energy resources with co-benefits for the country’s fast growing economy and environmental sustainability. This paper aims to present a comprehensive update on Turkey’s renewable and low-carbon energy sector. It reviews not only the current status of the technology, policy and economy, but also provides an insight into the social aspects as well. From a policy point of view, the paper critically discusses Turkey’s energy strategy and perspectives and from the social point of view, the paper argues that there is a research gap in recent literature regarding public awareness and social acceptance of low-carbon energy technologies. Also, the future challenges for promoting low-carbon society in Turkey are discussed in terms of sustainable development and socio-environmental conditions. [ABSTRACT FROM AUTHOR]

As energy plays a vital role in the modern lifestyle of any country, understanding how sustainable the energy system of a country remains an important policy issue. This paper reviews the comprehensiveness of existing metrics in tracking and tracing energy sustainability and finds that the existing multi-dimensional indicators do not capture the sustainability dimension adequately. This paper proposes a composite index, SEDI (Sustainable Energy Development Index), to fill the gap. SEDI focuses on establishing the sustainability level of both intra- and inter-generational needs. The paper discusses the methodology, data availability and initial country comparisons. It is found that SEDI has a positive correlation with both the Human Development Index (HDI) and the Energy Development Index (EDI) but provides a better understanding of the different dimensions of energy sustainability.

In order to promote the growth of renewable energy sector in Malaysia, feed-in tariff (FiT) mechanism has been introduced by Malaysian government in 2011, in accordance with Renewable Energy Act 2011 and Sustainable Energy Development Authority Act 2011. The tariff was enacted to overcome the shortcomings identified in the small renewable energy power (SREP) Program from 2001 to 2010. This paper highlighted some measures adopted to rectify the shortcomings identified during SREP, and the role of Sustainable Energy Development Authority (SEDA) in achieving the above mentioned task. The paper also includes the latest progress on renewable energy projects, especially those related to solar photovoltaic system. It is predicted that solar energy will become the main source of renewable energy in Malaysia by the year 2050. [ABSTRACT FROM AUTHOR]

China is vast, abundant and particularly plentiful in energy sources, due to which it has obtained remarkable achievements on economy. However, its energy structure is too simple to support the sustainable development of economy as coal still contributes to the majority of energy consumption in China. As a consequence, Renewable Energy Law was enacted in 2005, and Chinese government announced a series of policies to boom renewable energy industry. Subsidy policy is one of the major forms of these policies. This paper aims to present these subsidy policies and to analyze their effects according to relative data in energy industry 2005–2013, to find out the deficiencies and enlighten possible policy improvements. The original intentions and abstracts of 5 different levels of subsidy related policies are summarized, and the effects in reality are attentively analyzed. It can be concluded that subsidy policies have different short-term effect on different renewable energies, and they all show some negative effect to a certain extent. 6 core problems are summarized in this paper, and remedy strategies are suggested.

Energy is important for sustainable development, yet multidimensional challenges exist for policy makers in transformations to sustainable energy systems. Sustainable development is generally recognised as having a three-lens approach: development must balance impacts in the economic, environmental and cultural dimensions. While cultural themes such as governance, motivation, and social values are widely acknowledged in the literature as critical for transformations to sustainability, however, research on these themes has been scant. Culture influences many aspects of society; hence it is important to consider culture when developing policies for sustainable development. Understanding national cultures can lead to greater understanding of what shapes national policy and strategies for transformations to sustainable energy systems. Understanding cultural influences on policy can help other countries to overcome similar challenges in policy making, planning or local resource management. Comparisons between countries serve to further advance the understanding of approaches to such challenges. This paper examines transformations towards sustainable energy through the lens of culture, through a case study of geothermal development in Iceland and Japan. Using Hoftsede's cultural theory framework, we highlight cultural variables relevant to sustainability transformations, with particular emphasis on the challenges of the management of geothermal energy resources, and the management of related conflicts and public participation. We present our findings garnered from interviews with key players in the energy industry in both countries reinforced by an extensive literature review. We find that culture clearly influences the approach to geothermal energy development in both countries and we identify benefits and disadvantages to approaches on overlapping issues and challenges in both countries.

Central Africa possesses important renewable energy potential that continues to suffer from poor development. The primary cause of the poor use of renewable energy is the poor commitment and dedication among the region's governments who have not taken the necessary measures to support the sector. The primary purpose of this paper is to emphasize the renewable energy resources of Central Africa that they may be used optimally. The report also describes the availability of renewable energy resources and suggests actions to promote and sustain their development by improving access to sustainable, environmentally friendly, and affordable energy services, making significant improvements to energy infrastructure in Central Africa, and promoting renewable energy and energy efficiency. The work presents the potential for solar, biomass and hydropower, indicating where development is available. Next, the identified obstacles of clean energy promotion are targeted. Finally, suggestions are offered to help countries develop a vision aimed at developing good clean energy policy that increases the status of environmentally friendly energy. A Cameroon case study is examined as an illustration. Several documents are cited from institutions in the region and abroad. [ABSTRACT FROM AUTHOR]

At present, there is no specific legal basis for the development and utilisation of marine renewable energy, nor legal protection for the developers in China. The consequence is that the Chinese Government is unable to provide institutional support for the substantive development of marine renewable energy, resulting in slow development of China's marine energy industry. This paper provides an institutional framework for the establishment of relevant laws in China and legislative proposals in legal perspective, for the better development of marine renewable energy. The Chinese Government should optimise the administrative management system, strengthen financial regulation such as tax and emphasise sustainable development. [ABSTRACT FROM AUTHOR]

Abstract: This review paper sets the stage for a look at the Lithuanian (hereinafter LT) transport sector and its transition towards sustainable mobility through the use of biofuels and implementation of the necessary policies to deliver the renewable energy targets. The assessment begins with a brief and reasonably balanced situational analysis of the transport subsectors—road (including ex-fleet vehicle market), off-road, railway, marine, and air—in Lithuania, and their direct relations to the biofuel sector. The paper also aims to examine the dynamics of GHG emissions (N2O, CH4, CO2), air and soil pollution (NO2, SO2, NMWOC, NH3, PM, CO, heavy metals), and related indicators in the whole LT transport sector during the economic transition period (1990–1995), economy growth period (1996–2007) and the first-world debt crisis period (2007–2010). The national biofuels industry has seen plenty of ups and downs over the past decade but have generally good growth prospects. The study found that the CO2 emission is growing recently in Lithuania and this growth could be attributed to almost all transport subsectors. One of the main problems responsible for this situation is the patchy nature of the regulation (there is no governmental decision indicated on setting of national fuel economy/GHG standard), from which most other problems arise. Transport activity has been a key facilitator and driver of economic prosperity in Lithuania and it is likely to continue to grow. It can produce both positive and negative effects on the environment and the quality of life depending on measures at all levels to promote its sustainable development. [Copyright &y& Elsevier]

Abstract: This paper overviews previous research addressing the inclusion of the, social dimension of sustainable development on power systems planning. Consequences of the recent energy policies and strategies are already being felt in, developed countries’ power systems, with the integration of rising quotas in renewable, energy technologies. However, while the tools that aid decision making on power, planning show that economic and environmental issues are easily quantifiable and thus, modeled, social concerns have been addressed in a less extensive and more, subjective way, implying in most cases expert participation on multi-criteria decision aid, techniques. A survey of recent papers providing public perceptions on electricity, generation technologies and projects is presented. These papers were chosen and, reviewed in order to present a representative array of methodologies that are used to, assess social acceptance of technologies. According to some of the reviewed papers, this issue is suggested to be fundamental to increase project success. As a conclusion, stands the fact that further discussion is still needed in order to achieve solid, agreement, among experts, over what are the positive and the negative drivers to, social sustainability; otherwise models will not be able to translate reality and improve it, under this point of view.

Abstract: This paper analyses the reality of total renewable electricity scenario (TRES) from renewable energy sources (RES) as a totally green strategy of electric energy production. The paper is based on the EREC''s Agency forecast until the year 2040, which foresees the share of 82% of RES, extended to 100% of RES. The key element that creates conditions for achieving this ambitious scenario is an innovative combination of RES and pump storage hydroelectric (PSH) power plants, the so-called Concept-H, which can simultaneously use the energy of local RES (sun and wind) and local precipitation (natural waterflows) and in this way can provide continuous supply of electric power and energy to consumers. The methodology is based on the model of equivalent RES and equivalent reservoir that allows a comprehensive view of available RES and hydro system. The total required land use of RES system would be 29,517km2 of RES (which would amount to about 0.5% of the total technical potential of using RES), total reservoir volumes would be 880km3 (which is only 8% of all artificial reservoirs built in the world to the date) and the orientation estimate of investment in TRES would then be approximately 1% of world GDP in 2009, which clearly shows that the TRES is realistically feasible. It has been shown that implementation of the green strategy of energy balance fulfilling can be realized with present day technology. Precisely this fact shows that further increase of efficiency of RES and their combining into RES–PSH power plants, along with increase in the cost of classic power fuels and the growing needs for environment protection, the proposed solution of TRES realization could be widely important and thus become a serious alternative to the existing energy strategies and a guideline to decision makers throughout the world.

Abstract: Energy demand continues to increase in turn raising concerns about energy supply. In this paper, the author has tried to systematize the role of the energy sector in South Eastern (SE) Europe in the context of the European energy policy process. This should make the energy sector in SE Europe more visible and open to substantial activities and appropriate funding. This is important to assure its full alignment with the European energy policy process, and in so doing, make it less fragile. According to the SE European Energy Community Treaty, parties to the Treaty are obliged to implement reforms in the energy and environmental sector in accordance with the European Union''s respective policy. This paper raises awareness of the environmental requirements that have been set, of renewable energy and its implementation, at the same time pointing out that the response in SE Europe has been at a low level. It is believed that this paper could draw attention to the existing problems and could contribute to the establishment of a common integrated energy market in SE Europe and the EU.

Iran is rich in energy resources and oil has dominated the politico-socio-economic life of this country, but nevertheless Iran has no documented policy and vision for its massive resources. This poses a major challenge to policy makers and the society. It is necessary to have a clear picture of Iran׳s energy status in recent years showing the flow of energy supply, demand, consumption, import and export to know how the energy situation in Iran is and identify its weaknesses and strengths. This paper is the first step in that direction and presents an overview of Iran energy situation and the potential and current state of renewable energy application. The status of energy in Iran is compared to world’s energy status via five key factors, and finally this comparison shows hints for designing roadmap of energy for Iran to attain sustainable and secure energy in long term. The novel contribution of this work is the STEEP analysis of Iran energy situation for designing the long-term supporting mechanisms for sustainable and secure energy for Iran based on Social (S), Technological (T), Economical (E), Environmental (E) and Political (P) criteria.

Achieving sustainable energy development in a region requires rational use of energy resources and technologies, and the development of appropriate policies. Three concerns are therefore required to achieve these issues: (i) to acquire a picture of the local current energy situation, (ii) to measure the state of development and the progress towards a sustainable energy system, and (iii) to have energy decision- and policy-makers fully aware of the implications on sustainable development of selected policies. It is in this perspective and in the frame of activities on sustainable energy for all and access to energy in developing countries carried out by the UNESCO Chair in Energy for Sustainable Development, that we developed this review. The objective of this paper is to depict the current energy situation of Africa by using the most up to date data, describing it as far as the concept of sustainable development is concerned, and to see if and how energy policies promoted by local players fit with this asset. We assess the energy situation of Africa by combining (i) data, mainly by the International Energy Agency, about national energy balances for primary and electric energy, the Energy Development Index and energy resources, with (ii) a more comprehensive analysis of the African energy system, accomplished by the Energy Indicators for Sustainable Development. An overview of the energy-related policies and action plans developed by different local players in the African continent is also carried out with the goal of providing remarks by coupling such plans with the above mentioned energy analysis.

Abstract: Renewable energy is considered as a solution for mitigating climate change and environmental pollution; however, an important problem of the application of renewable energy systems (RESs) is that the evaluation of the sustainability of these systems is extremely complex. In order to assess the sustainability of renewable energy systems comprehensively, the use of sustainability indicators (SIs) is often necessary. Since sustainability indicators are necessary to reflect various aspects of sustainability, the development of a general sustainability indicator (GSI) including many basic sustainability indicators (BSIs) becomes critical. In this paper, the methods of selection, quantification, evaluation and weighting of the basic indicators as well as the methods of GSI aggregation are reviewed. The advantages and disadvantages of each method are discussed. Based on these discussion and the analysis of the uncertainties of sustainability assessment, an effective framework and its procedures of the development of GSI for renewable energy systems is presented. This GSI is not only able to evaluate all the sustainability criteria of RESs, but also can provide numerical results of sustainability assessment for different objective systems. The proposed framework in this study can be used as a guidance of the development of sustainability indicator for various renewable energy systems. [Copyright &y& Elsevier]

Abstract: The aim of the study was to present the current status of the electrical energy market, energy legislation, green house gas emissions, energy consumption trends and future prospects of sustainable development in Greece. The study described current issues relevant to the renewable energy sources (RES) such as the climatic factors that affect the penetration of RES into the Greek energy mix, the current regulation status, the barriers and evaluation of their contribution in the energy balance. The study also investigated the increasing power demand, emissions and energy trends in the residential sector in Greece. The paper evaluated the current status of the building stock, RES and the future energy related prospects of the Aegean Sea islands. The islands were categorized based on energy production cost, heating degree days, building characteristics and natural resources to identify islands with higher and lower renewable energy potentials. The study revealed that the islands with the higher potential energy savings in the residential sector are Lesbos, Lemnos, Samothrace, Chios, Andros, Patmos, Kea and Kimolos while at the same time, Rhodes, Naxos, Amorgos, Syros, Ios and Kythnos are those islands that present the lower potential. The study will help to propose action plans and implementation strategies in terms of residential renewable energy applications in non-grid interconnected islands in Greece. [Copyright &y& Elsevier]

Abstract: In order to realize the sustainable development of country and society, many countries have established their renewable energy law and development strategy no matter developed countries or developing countries. It is well known that China is the largest developing country in the world, and the per capita GDP ranks more than 100, however, the total GDP ranks the second due to the huge population amount, and just behind USA. Certainly, the total energy consumption amount is huge, and the big energy demand has brought a serious of environmental problems such as acid rain, water and soil pollution, and resource exhaustion, etc. Fortunately, China central government has regarded the serious question to realize the sustainable development in future. The renewable energy law has been established in 2005. Firstly, China''s energy situation and existing environmental questions in past years is introduced in this paper. Secondly, the distribution and the application practice of different renewable energy were introduced. Then, China''s renewable energy policy is detailed introduced in the following section. The next section discusses the existing questions. Based on these discussions, the development barriers and recommendations are introduced, respectively. [Copyright &y& Elsevier]

Abstract: Increasing the share of renewable energy in the national energy mix remains one of the major energy policy goals across many economies. This paper assesses the roles and potentials of renewable energy sources in less-developed economies while citing Nepal as an example. Renewable energy has a significant role to play in the electrification of rural areas in developing economies and contribute towards sustainable development. Realizing full potentials of renewable, however, requires addressing both the associated demand-side and supply-side constraints. Innovative subsidies and tax incentives, adequate entrepreneurial support, strengthening institutional arrangement and promoting local community-based organizations such as the cooperatives are the necessary factors in promoting the green technologies in countries like Nepal. International factors such as large scale investment and adequate technology transfer are equally crucial to create a rapid spread and increase affordability of decentralized renewable energy technologies in less-developed economies.

Abstract: Energy is an essential factor to achieve sustainable development. So, countries striving to this end are seeking to reassess their energy systems with a view towards planning energy programmes and strategies in line with sustainable development goals and objectives. As would be expected, the rapid expansion of energy production and consumption has brought with it a wide range of environmental issues at the local, regional and global levels. States have played a leading role in protecting the environment by reducing emissions of greenhouse gases. Turkey is an energy importing country with more than half of the energy requirement being supplied by imports, and air pollution is becoming a great environmental concern in the country. On the other hand, Turkey''s geographical location has several advantages for extensive use of most of the renewable energy sources. In this regard, renewable energy resources appear the most efficient and effective solutions for clean and sustainable energy development in Turkey. This paper provides an overview of global energy use and renewables for clean and sustainable energy policies in Turkey. [Copyright &y& Elsevier]

Abstract: This paper evaluates small hydropower (SHP) development and examines the current situation in Nigeria with respect to the established policies and Energy Power Sector Reform (EPSR) Act 2005. Hydropower sector witnessed about 360% growth between 1971 and 2005 and yet only about 5% of the vast small hydropower (SHP) potential is tapped by the few plants built between 1923 and 1964. Operating and maintenance costs are in favor of SHP development in the country, being the lowest when compared with the situation in European countries. The Nigerian Government has taken steps to diversify energy sources in order to promote renewable energy development by encouraging private investments in the energy sector through reforms, but this may not be adequate as there remain barriers against SHP development in the country. It is concluded that government must incorporate subsidies, feed-in-tariffs, and framework for Price Purchase Agreements (PPA) into the policies in order to further promote renewable energy and attract both indigenous and foreign investments for quick adoption and rapid expansion of SHP technologies.

Abstract: Academics, practitioners, and policy makers continue to debate the benefits and costs of alternative sources of energy. Environmental and economic concerns have yet to be fully reconciled. One view is that decisions that incorporate both society''s concern with the environment and investors’ desire for shareholder value maximization are more likely to be truly sustainable. We coin the term dual sustainability to mean the achievement of environmental and financial sustainability simultaneously. Many experts believe that wind energy can help to meet society''s needs without harming future generations. It is clean and renewable. Because the fuel is free it provides the ultimate in energy independence. Wind energy has emerged as a leading prospect, in part, because it is considered by many to be environmentally sustainable. However, a key question that remains is whether wind energy is financially sustainable without the extensive government support that has helped to create and nurture this growth industry. Using reliable, proprietary data from field research, our analysis employs a capital budgeting framework to evaluate the financial economics of investments in wind energy. We find that because of the convergence of improved technology, greater efficiency, and with the increasing cost of traditional, competing sources such as oil and natural gas, wind energy is close to becoming self-sustaining financially without the extensive federal government support that exists today. Wind energy can provide the best of both worlds. It is sustainable from an environmental perspective and it is becoming sustainable financially. In short, those companies investing in wind energy will be able to do well by doing good. Perhaps the achievement of dual sustainability is true sustainability. Our research findings and dual sustainability have several interesting and important implications for public policy towards wind energy. All imply that public policy can now be executed in a more effective and efficient manner. In the paper we outline and offer these better and cheaper public policy alternatives for consideration.

The general perception of small run-of-river hydropower plants as renewable energy sources with little or no environmental impacts has led to a global proliferation of this hydropower technology. However, such hydropower schemes may alter the natural flow regime and impair the fluvial ecosystem at different trophic levels. This paper presents a global-scale analysis of the major ecological impacts of three main small run-of-river hydropower types: dam-toe, diversion weir, and pondage schemes. This review's main objective is to provide an extensive overview of how changing the natural flow regime due to hydropower operation may affect various aspects of the fluvial ecosystem. Ultimately, it will inform decision-makers in water resources and ecosystem conservation for better planning and management. This review analyses data on ecological impacts from 33 countries in five regions, considering the last forty years' most relevant publications, a total of 146 peer-reviewed publications. The analysis was focused on impacts in biota, water quality, hydrologic alteration, and geomorphology. The results show, notably, the diversion weir and the pondage hydropower schemes are less eco-friendly; the opposite was concluded for the dam-toe hydropower scheme. Although there was conflicting information from different countries and sources, the most common impacts are: water depletion downstream of the diversion, water quality deterioration, loss of longitudinal connectivity, habitat degradation, and simplification of the biota community composition. A set of potential non-structural and structural mitigation measures was recommended to mitigate several ecological impacts such as connectivity loss, fish injuries, and aquatic habitat degradation. Among mitigation measures, environmental flows are fundamental for fluvial ecosystem conservation. The main research gaps and some of the pressing future research needs were highlighted, as well. Finally, interdisciplinary research progress involving different stakeholders is crucial to harmonize conflicting interests and enable the sustainable development of small run-of-river hydropower plants. [Display omitted] • Eco-friendliness of run-of-river hydropower plants is questionable when it is intensively developed. • Periodic water depletion degrades fluvial habitats and reduces connectivity. • Environmental flows remain overlooked in run-of-river hydropower plants. • Pondage hydropower scheme induces the highest ecological impacts. • Run-of-river hydropower plants do not always have a direct impact on fluvial ecosystems.
