Renewable energy market conditions and barriers in Turkey

Decentralized wind, hydropower, biogas and biomass, geothermal, solar thermal and solar electricity energy systems are the most commonly found renewable energy technologies promoted for rural energy supply within sustainable developments programs. They are, therefore, seen to have a central place in the practice of sustainable development and in allowing less development countries to bypass the environmentally damaging fossil fuel intensive paths made by industrialized countries. On the political front, many less development countries are critical of pressure on them to adopt environmental energy technologies.Turkey is situated the meeting point of three continents (Asia, Europe and Africa) and stands as a bridge between Asia and Europe. The country is located in southeastern Europe and southwestern Asia. As Turkey’s economy has expanded in recent years, the consumption of primary energy has increased. Presently in order to increase the energy production from domestic energy resources, decrease the use of fossil fuels as well as reduce of green house gas emissions different renewable energy sources are used for energy production in Turkey. The share of energy production from renewable energy sources has increased during the last 10 years. Turkey must import most of the energy to meet her needs. Turkey also has a large potential for renewable energies. The lack of knowledge about renewable energy technologies by most policy-makers, potential consumers, and energy firm managers has played against renewable energy developments. The paper presents renewable energy used in Turkey and Europe Union and evaluation of the market conditions and barriers of renewable energy use in Turkey.     

Renewable energy strategies for sustainable development

This paper discusses the perspective of renewable energy (wind, solar, wave and biomass) in the making of strategies for a sustainable development. Such strategies typically involve three major technological changes: energy savings on the demand side, efficiency improvements in the energy production, and replacement of fossil fuels by various sources of renewable energy. Consequently, large-scale renewable energy implementation plans must include strategies for integrating renewable sources in coherent energy systems influenced by energy savings and efficiency measures. Based on the case of Denmark, this paper discusses the problems and perspectives of converting present energy systems into a 100% renewable energy system. The conclusion is that such development is possible. The necessary renewable energy sources are present, and if further technological improvements of the energy system are achieved the renewable energy system can be created. Especially technologies of converting the transportation sector and the introduction of flexible energy system technologies are crucial.     

Turkey's Renewable Energy Facilities in the Near Future

In this work, renewable energy facilities of Turkey were investigated. Electricity is mainly produced by thermal power plants, consuming coal, lignite, natural gas, fuel oil and geothermal energy, and hydro power plants in Turkey. Turkey has no large oil and gas reserves. The main indigenous energy resources are lignite, hydro and biomass. Turkey has to adopt new, long-term energy strategies to reduce the share of fossil fuels in primary energy consumption. For these reasons, the development and use of renewable energy sources and technologies are increasingly becoming vital for sustainable economic development of Turkey. The most significant developments in renewable production are observed hydropower and geothermal energy production. Renewable electricity facilities mainly include electricity from biomass, hydropower, geothermal, and wind and solar energy sources. Biomass cogeneration is a promising method for production bioelectricity.     

Potential of renewable hydrogen production for energy supply in Hong Kong

Hong Kong is highly vulnerable to energy and economic security due to the heavy dependence on imported fossil fuels. The combustion of fossil fuels also causes serious environmental pollution. Therefore, it is important to explore the opportunities for clean renewable energy for long-term energy supply. Hong Kong has the potential to develop clean renewable hydrogen energy to improve the environmental performance. This paper reviews the recent development of hydrogen production technologies, followed by an overview of the renewable energy sources and a discussion about potential applications for renewable hydrogen production in Hong Kong. The results show that although renewable energy resources cannot entirely satisfy the energy demand in Hong Kong, solar energy, wind power, and biomass are available renewable sources for significant hydrogen production. A system consisting of wind turbines and photovoltaic (PV) panels coupled with electrolyzers is a promising design to produce hydrogen. Biomass, especially organic waste, offers an economical, environmental-friendly way for renewable hydrogen production. The achievable hydrogen energy output would be as much as 40% of the total energy consumption in transportation.     

Biomass energy perspective in Pakistan based on chemical looping gasification for hydrogen production and power generation

Biomass has appeared as one of the most encouraging renewable energy sources for the replacement of fossil fuels. An extensive study about the prospective of biomass to produce renewable energy in Pakistan has been exhibited in this article, which takes into account Pakistan's current energy and future potential. A new generation of transformative energy conversion technologies has been developed, including chemical looping. This technique has the potential to control air pollution and clean fuel production, all of which have been major global challenges of this century. Through recent research, the study aims to aid in understanding of biomass-based chemical looping gasification and its development. CHP and CCHP systems are developed processes that produce power, heat, and cooling. Systems using fuel cells have greater efficiency, between 60 and 70%. Additionally, the SOFC-based power generating techniques are associated with the best electrical efficiency (67%).     

Renewable electricity in Sweden: an analysis of policy and regulations

This study aims to analyse the developments in renewable energy policy making in Sweden. It assesses the energy policy context, changes in the choice of policy instruments, and provides explanations behind policy successes and failures. Swedish renewable energy policy has been developing in a context of uncertainty around nuclear issues. While there has been made a political decision to replace nuclear power with renewables, there is a lack of consensus about the pace of phasing out nuclear power due to perceived negative impacts on industrial competitiveness. Such uncertainty had an effect in the formulation of renewable energy policy. Biomass and wind power are the main options for renewable electricity production. Throughout 1990s, the combined effect of different policy instruments has stimulated the growth of these two renewable sources. Yet, both biomass and wind power are still a minor contributor in the total electricity generation. Lack of strong government commitment due to uncertainty around nuclear issues is a crucial factor. Short-term subsidies have been preferred rather than open-ended subsidy mechanisms, causing intervals without subsidies and interruption to development. Other factors are such as lack of incentives from the major electricity companies and administrative obstacles. The taxation system has been successful in fostering an expansion of biomass for heating but hindered a similar development in the electricity sector. The quota system adopted in 2003 is expected to create high demand on biomass but does not favour wind power. The renewable energy aims are unlikely to be changed. Yet, the future development of renewable energy policies especially for high-cost technologies will again depend strongly on nuclear policies, which are still unstable and might affect the pace of renewable energy development.     

Renewable energy in India: Current status and future potentials

Renewable energy sources and technologies have potential to provide solutions to the long-standing energy problems being faced by the developing countries. The renewable energy sources like wind energy, solar energy, geothermal energy, ocean energy, biomass energy and fuel cell technology can be used to overcome energy shortage in India. To meet the energy requirement for such a fast growing economy, India will require an assured supply of 3–4 times more energy than the total energy consumed today. The renewable energy is one of the options to meet this requirement. Today, renewable account for about 33% of India's primary energy consumptions. India is increasingly adopting responsible renewable energy techniques and taking positive steps towards carbon emissions, cleaning the air and ensuring a more sustainable future. In India, from the last two and half decades there has been a vigorous pursuit of activities relating to research, development, demonstration, production and application of a variety of renewable energy technologies for use in different sectors. In this paper, efforts have been made to summarize the availability, current status, major achievements and future potentials of renewable energy options in India. This paper also assesses specific policy interventions for overcoming the barriers and enhancing deployment of renewables for the future.     

Renewable energy sources in Turkey for climate change mitigation and energy sustainability

In Turkey, there is a much more potential for renewables, but represent about 37% of total energy production and 10% of total energy consumption. This share is not enough for the country and the governments should be increase to this situation. Renewable energy technologies of wind, biomass, hydropower, geothermal, solar thermal and photovoltaics are finally showing maturity and the ultimate promise of cost competitiveness. With respect to global environmental issues, Turkey's carbon dioxide emissions have grown along with its energy consumption. States have played a leading role in protecting the environment by reducing emissions of greenhouse gases. 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. Turkey's geographical location has several advantages for extensive use of most of these renewable energy sources. Certain policy interventions could have a dramatic impact on shaping the relationship between geological, geographic and climatic conditions and energy production. This study shows that there is enough renewable energy potential in Turkey for fuels and electricity. Especially hydropower and biomass are very well.     

Developing markets for renewable energy technologies

Although renewable energy resources are now being utilised more on a global scale than ever before, there is no doubt their contribution to the energy economy can still be greatly increased. Recently international support for developing these relatively new sources of energy has been driven by their benefits as assessed by reduced environmental impact, particularly reduced greenhouse gas emissions.After several decades of continuous but somewhat erratic funding for research and development of renewables, it is time to take stock of the key issues to be addressed in terms of implementation of major renewable energy programmes on a large scale worldwide. One of the first steps in this process is the identification and encouragement of reliable continuous markets both in developed and developing nations. Future energy policy and planning scenarios should take into account the factors necessary to integrate renewables in all their diverse forms into the normal energy economy of the country.Other critical factors in market development will include the mass production of high quality, reliable and reasonable cost technical products and the provision of adequate finance for demonstrating market ready and near market renewables equipment.Government agencies need to aid in the removal of legislative and institutional barriers hindering the widespread introduction of non-conventional energy sources and to encourage the implementation of government purchasing schemes.Recent moves by companies in Australia to market ‘green energy’ to customers should also aid in the public awareness of the ultimate potential of renewables leading to greater use in the industrial, commercial and domestic sectors.     

Current status of renewable energy in Nepal: Opportunities and challenges

Energy is indispensible in modern society and is one of the most important components of socio-economic development. Nepal is one of the least developed countries with more than 80% of its population residing in rural communities. Per capita energy usage – often viewed as a key index of the development – in the country is far less than the global average per capita energy usage. The energy sector is dominated by the traditional energy sources such as fuel woods, crop residues and animal dung mainly for domestic usage contributing to about 86% of the national energy consumption. Currently 40% of the population has access to electricity, and the rural electrification accounts for only 29%. The majority of rural populations are meeting their energy needs by burning biomass in traditional stoves which has several environmental and public health issues. Nearly all fossil-derived fuels consumed in the country are imported in a refined form, and the perpetual increase in petroleum imports has adversely impacted the existing fragile economy of the country. Despite a huge potential in harnessing various renewable energy resources such as hydropower, solar power, wind energy and biofuels/bioenergy, these resources have not been sustainably captured due to geographical, technical, political and economical reasons. This paper presents a brief account of Nepal's renewable energy resources and the current status of various renewable energy technologies (RETs) such as micro-hydro, solar power, wind energy, biofuel/bioenergy, improved cook stoves, and improved water mill. It also highlights the opportunities and barriers for the development of RETs. Finally this paper presents some recommendations for the promotion, development and implementation of RETs in the country.     

Assessment of the potential for hydrogen production from renewable resources in Argentina

The potential for hydrogen production from three major renewable resources (wind energy, solar energy and biomass) in Argentina is analyzed. This potential for the annual production of wind, solar and biomass hydrogen is represented with maps showing it per unit area in each department. Thus, by using renewable resource databases available in the country, a new Geographic Information System (GIS) of renewable hydrogen is created. In this system, several geographic variables are displayed, in addition to other parameters such as the potential for renewable hydrogen production per department relative to transport fuel consumption of each province or the environmental savings that would imply the production of hydrogen required to add 20% V/V to CNG, with the aim of developing the cleaner alternative CNG + H₂ fuel. In order to take into account areas where energy development would be restricted, land use and environmental exclusions were considered.     

The energy sector in Eritrea—institutional and policy options for improving rural energy services

The energy consumption patterns and in particular, those of the rural household and small and medium enterprises (SMEs) in Eritrea are assessed. Eritrea's total final energy consumption in 1998 was estimated to be around 619,580 toe, of which 68% was consumed by the household sector, 16% by the commercial/public sector, 13% by transport and 3% by industry. The sources of energy were 66.3% biomass based (fuelwood, dung, charcoal, agri-residue), 31% oil products and 2% electricity. It is also noted that 98% of the rural population and 20% of the urban residents do not have access to electricity. Over 80% of the energy needs of rural enterprises is met by biomass or animate/human labour. To analyse the root problems hindering the wider dissemination of modern energy services to rural areas, two key hypotheses related to policy and institutional framework were selected and tested. The findings indicate that Eritrea has general energy policies pertaining to the development of electricity, oil and renewable energy sub-sectors for the benefit of the public and the economy. The absence of sharply focussed, pro-rural energy policy and/or their policy instruments has been observed. The key problem is, however, the weakness in implementation of rural energy projects and programmes. This is mainly due to inappropriate institutional structure and/or gaps in the structure, in addition to lack of corporate culture; poor incentives for workers; and, poor linkages among the various stakeholders concerned in energy for rural development.     

Renewable energy resources and technologies applicable to Ireland

The energy consumed in Ireland is primarily achieved by the combustion of fossil fuels. Ireland's only indigenous fossil fuel is peat; all other fossil fuels are imported. As fossil fuels continually become more expensive, their use as an energy source also has a negative impact on the environment. Ireland's energy consumption can be separated into three divisions: transportation, electricity generation and heat energy. Ireland however has a vast range of high quality renewable energy resources. Ireland has set a target that 33% of its electricity will be generated from renewable sources by 2020 [I. Government. Delivering a Sustainable Energy Future for Ireland; 2007.]. The use of biomass, wind and ocean energy technologies is expected to play a major part in meeting this target. The use of renewable energy technologies will assist sustainable development as well as being a solution to several energy related environmental problems. This paper presents the current state of renewable energy technologies and potential resources available in Ireland. Considering Ireland's present energy state, a future energy mix is proposed.     

The achievement,significance and future prospect of China's renewable energy initiative

China's high-speed economic growth and ambitious urbanization depend heavily on the massive consumption of fossil fuel. However, the over-dependence on the depleting fossil fuels causes severe environmental problems, making China the largest energy consumer and the biggest CO₂ emitter in the world. Faced with significant challenges in terms of managing its environment and moving forward with the concept of sustainable economic development, the Chinese government plans to move away from fossil fuels and rely on renewables such as hydropower, wind power, solar power, biomass power and nuclear power. In this paper, the current status of China's renewable energy deployment and the ongoing development projects are summarized and discussed. Most recent developments of major renewable energy sources are clearly reviewed. Additionally, the renewable energy development policies including laws and regulations, economic encouragement, technical research and development are also summarized. This study showcases China's achievements in exploiting its abundant domestic renewable energy sources to meet the future energy demand and reducing carbon emissions. To move toward a low carbon society, technological progress and policy improvements are needed for improving grid access (wind), securing nuclear fuel supplies and managing safety protocols (nuclear), integrating supply chains to achieve indigenous manufacture of technologies across supply chains (solar). Beyond that, a preliminary prediction of the development of China's future renewable energy developments, and proposes targeted countermeasures and suggestions are proposed. The proposal involves developing smart-grid system, investing on renewable energy research, improving the feed-in tariff system and clarifying the subsidy system.     

The status,predicament and countermeasures of biomass secondary energy production in China

China is rich in biomass resources, with favorable conditions for the development and utilization of biomass energy. Currently, the main secondary forms of biomass energy utilized in China include biogas, biomass power, bioethanol, biodiesel. By the end of 2010, the annual output of biogas in China had reached 14.3×10⁹ m³; the installed capacity of biomass power had reached 5.5×10⁶ kw; the annual output of bioethanol had reached 1.84×10⁶ t; the annual output of biodiesel was 400×10³ t. Although China is very rich in biomass resources, the percentage of biomass energy in the total energy utilized in China is very low. In 2010, the biomass secondary energy accounted for 7.28% of the total renewable energy consumption; and only 0.66% of the primary energy consumption in China. Compared with other types of renewable energy, the biomass energy development remains very slow and even marginalized. The development of secondary sources of energy in China is relatively slow, the reasons for which are many, such as food security, high production costs, obsolete equipment, technological immaturity, insufficient raw materials, and a serious shortage of investments. In fact, the root causes for the slow development of the biomass secondary energy industry are the government's focus on economic development and the private enterprises focus on economic benefits. The lower economic benefits of the biomass secondary energy industry do not intrinsically motivate them to promote its development. Entering the market is crucial to the development of the biomass secondary energy and requires strong implementation and policy guarantees by the government. Biomass secondary energy has a positive role in reducing greenhouse gas emission, reducing waste pollution, and increasing employment opportunities. It is recommended that the government and enterprises should actively promote the development of the biomass secondary energy.     

A review of catalytic hydrogen production processes from biomass

Hydrogen is believed to be critical for the energy and environmental sustainability. Hydrogen is a clean energy carrier which can be used for transportation and stationary power generation. However, hydrogen is not readily available in sufficient quantities and the production cost is still high for transportation purpose. The technical challenges to achieve a stable hydrogen economy include improving process efficiencies, lowering the cost of production and harnessing renewable sources for hydrogen production. Lignocellulosic biomass is one of the most abundant forms of renewable resource available. Currently there are not many commercial technologies able to produce hydrogen from biomass. This review focuses on the available technologies and recent developments in biomass conversion to hydrogen. Hydrogen production from biomass is discussed as a two stage process – in the first stage raw biomass is converted to hydrogen substrate in either gas, liquid or solid phase. In the second stage these substrates are catalytically converted to hydrogen.     

中国可再生能源发展进入阶段转换期

本世纪前10年,中国可再生能源采取开放型发展模式,凭借风电产业"以市场换技术"的战略及光伏产业"两头在外"的发展模式,加之国内政策的大力扶持,连续3年保持全球风电第一大国地位,2011年中国光伏电池产量占到全球产量的56.5%,光伏组件出口量占当年全球新增光伏装机容量的54.6%。然而自2010年末起,中国可再生能源产业频繁遭遇国外"双反"制裁,正面临"保护难"和"出口难"的两难困境,"以市场换技术"战略难以为继,"两头在外"的发展模式也走到了尽头。开放式的发展模式已不适合产业的进一步发展,中国可再生能源产业开始步入主要依靠国内市场、依靠自主创新的内向化发展新阶段。中国的可再生能源市场前景广阔,国内市场足以支撑产业的发展。虽然国外企业在技术水平方面领先于中国企业,但由于技术边界效应的存在,中国企业在国内市场上还是有优势的。新阶段中国的产业政策应该转向大力开发国内市场,将补贴产品的生产和贸易环节改为补贴生产要素,并加大对可再生能源消费端的补贴。同时,要加快提升企业自主创新能力和产业技术水平。     

Governmental policy and prospect in electricity production from renewables in Lithuania

In Lithuania, the generation of electricity is based on the nuclear energy and on the fossil fuels. After the decommissioning of Ignalina nuclear power plant in 2009, the Lithuanian Power Plant and other thermal plants will become the major sources of electricity. Consequently, the Lithuanian power sector must focus on the implementation of renewable energy projects, penetration of new technologies and on consideration of the future opportunities for renewables, and Government policy for promoting this kind of energy. Production of electricity from renewable energy is based on hydro, biomass and wind energy resources in Lithuania. Due to the typical climatic condition in Lithuania the solar photovoltaics and geothermal energy are not used for power sector. Moreover, the further development of hydropower plants is limited by environmental restrictions, therefore priority is given to wind energy development and installation of new biomass power plants. According to the requirements set out in the Directive 2001/77/EC of the European Parliament and of the Council of 27 September 2001 on the promotion of electricity produced from renewable energy sources in the internal electricity market [Official Journal L283, 33–40, 27 October 2001], 7% of gross consumption of electricity will be generated from renewable energy by 2010 in Lithuania. The aim of this paper is to show the estimation of the maximum renewable power penetration in the Lithuanian electricity sector and possible environmental impact.     

Five years left – How are the EU member states contributing to the 20% target for EU's renewable energy consumption; the role of woody biomass

The European Union has set ambitious targets of raising the share of EU energy consumption produced from renewable resources from 20% by 2020 to 27% by 2030. The aim of this paper is to assess the role of woody biomass in renewable energy as gross final energy consumption in the European Union (the EU-28). The paper identifies leading and lagging countries in biomass development by focusing on their current biomass use and forecasts future perspectives. The research compares and evaluates the role of biomass in renewable energy in the EU-28 focusing on countries' potential resources and policy support. The study shows that all countries are making efforts to reach the 20% target in 2020 and exhibit a trend of increasing renewable energy as gross final energy consumption towards the new target of 2030. Solid biomass plays an important role in reaching the EU's renewable energy targets. The majority of the EU-28 countries are close to reaching their national renewable energy targets and show a very attractive biomass development. Unless energy consumption decreases however, some member states will face serious problems in reaching their renewable energy target in 2020. Following our analysis, the largest problems occur in those MS having a relative high-energy consumption pattern: France, Germany and the United Kingdom. It is unlikely that they can comply with expected renewable energy demand, unless they mobilize more woody biomass from their available domestic potential (France, Germany) or considerably increase their woody biomass imports (mostly wood pellets) from elsewhere (United Kingdom).     

我国可再生能源发展对策

可再生能源的开发利用是应对气候变化和满足能源需求持续增长的最现实的举措。2009年我国风电和太阳能光伏发电保持了快速发展势头,其中风电装机容量估计达到约2200×104kW,但非化石能源消费量在能源消费总量中所占的比重仍然很低。2009年,我国能源消费总量约为31×108t标煤,其中水电、核电、风电等商品化非化石能源消费量约为2.3×108t标煤,约占能源消费总量的7.4%。要完成到2020年我国非化石能源在能源消费总量中所占比例达到15%的目标,任务非常艰巨。加快开发利用可再生能源是能源发展的重要任务之一,到2020年,可再生能源开发利用总量将在2008年的基础上增加2倍以上。我国目前和今后10多年时间内,可再生能源发展的重点是水电、风电、太阳能和生物质能。加快发展我国可再生能源的举措有:①继续做好水电建设工作,促进水电持续健康发展;②有序推进风电的规模化发展,显著提高风电在电力结构中的比重;③加快推广太阳能利用技术,扩大太阳能开发利用规模;④因地制宜开发利用生物质能,提高生物质能利用的现代技术水平。
