Resource potential and scope of utilization of renewable energy in Jammu and Kashmir, India

Jammu and Kashmir the northern most state of India is blessed with immense potential for utilization of renewable energy. The state at present is fairly untapped in terms of energy utilization and thus venturing into this region would definitely prove to be profitable. The natural energy sources like sunshine, wind, vegetation, water flow, biomass and other biological wastes though abundantly available in the state yet are not being potentially harnessed resulting in very low per capita energy availability, deforestation and poor health. Renewable energy acquires a promising option not only for energy availability next view and of environment protection but also the socio-economic conditions of the people residing in these areas can be improved to a great extent. The hydroelectric power has tremendous potential for generation of electricity in the state because the topography of the state provides extensive network of canals and streams. This paper describes the resource potential and opportunity to enter the market and bring more renewable energy projects in the form of solar, biomass derived fuels, biogas and hydroelectric in the state.     

Assessing the potential of renewable energy sources in Turkey

To meet Turkey’s growing energy demand, the installed electric power capacity of 27.8 GW in 2001 has to be doubled by 2010 and increased fourfold by 2020. The difference between Turkey’s total primary energy supply (TPES) of from its own sources and total final consumption (TFC) is projected grow from 1 quad (1.06–2.06) in 1999 to 5.71 quads (2.79–8.5) in 2020 (1 QUAD=293.071 TWh). Turkey’s limited amount of fossil fuels has a present average ratio of proved reserves of 97.38 quads to production rate of 3.2 quads yr⁻¹ of about 30 years. Turkey’s reliance on fossil fuel-based energy systems to meet the growing demand is most likely to exacerbate the issues of energy insecurity, national environmental degradation, and global climate change in increasing proportions. Economically-feasible renewable energy potential in Turkey is estimated at a total of ca. 1.69 quads yr⁻¹ (495.4 TWh yr⁻¹) with the potential for 0.67 quads yr⁻¹ (196.7 TWh yr⁻¹) of biomass energy, 0.42 quads yr⁻¹ (124 TWh yr⁻¹) of hydropower, 0.35 quads yr⁻¹ (102.3 TWh yr⁻¹) of solar energy, 0.17 quads yr⁻¹ (50 TWh yr⁻¹) of wind energy, and 0.08 quads yr⁻¹ (22.4 TWh yr⁻¹) of geothermal energy. Pursuit and implementation of sustainability-based energy policy could provide about 90 and 35% of Turkey’s total energy supply and consumption projected in 2010, respectively. Utilization of renewable energy technologies for electricity generation would necessitate about 23.2 Mha (29.8%) of Turkey’s land resources.     

Electricity generation from renewable energy sources in Poland

AbstractFor the European Union's Member States 2001/77/EC Directive on the promotion of electricity produced from renewable energy sources in the internal electricity market determined targets for 2010 of 21% share of electricity from renewable energy sources in total electricity consumption. Particular Member States adopted different measures for development of renewable and in consequence they achieved different results. Poland, being Member State of the EU since 2004 has accepted target of 7.5% for electricity generated from renewable energy sources until 2010. Currently, in this decade, new 2009/28/EC Directive on the promotion of the use of energy from renewable sources plays significant role in development of renewable energy sources. Directive set new target for 2020. Nowadays is a time for summary and assessment of results fulfilling Directives and monitor progress of new targets. Article presents measures implemented for renewable source energy development, also current state and perspectives of using of renewable energy sources in Poland and in the EU.     

Present status of renewable energy resources in Jammu and Kashmir State of India

Jammu and Kashmir State of India is one of the energy starved states despite of having tremendous potential for utilization of renewable energy. The natural energy sources like sunshine, wind, vegetation, water flow, biomass and other biological wastes are abundantly available in the state yet are not being potentially harnessed resulting in very low per capita energy availability forcing peoples to use wood resulting into deforestation. The fossils fuels, which pollute the environment, are extensively utilized even though they are not sustainable. Developing and properly implementing renewable energy technologies in this state can provide secure energy supply for rapid domestic and industrial development which will attract new investments, thereby creates additional employment. It shall also generate additional state income by allowing the state to sell renewable energy trading certificates to other states. Therefore, it is important that the region moves to clear and sustainable energy. This paper presents an overview of the present status of renewable energy development and summarizes key issues in each of the major industrial segments. It also examines crucial gaps in the renewable energy market, describes the goals set out by various government programs, and estimates the resources and effort required to meet these goals.     

Potential of the renewable energy development in Jammu and Kashmir,India

The future economic growth for India is likely to result in rapid and accelerated surge in energy demand, with expected shortages in terms of supply. Many of its current policies and strategies are aimed at the improvement and possible maximization of energy production from the renewable sector. It is also clear that while energy conservation and energy efficiency can make an important contribution, renewable energies will be essential to the solution and are likely to play an increasingly important role for providing enhanced energy access, reducing consumption of fossil fuels, and helping India pursue its low-carbon progressive pathway. However, most of the states in India, like the northernmost state of Jammu and Kashmir, have experienced an energy crisis over a sustained period of time and the government both at center and state level has to embark upon with these pressing issues in a more sustainable manner and accordingly initiate various renewable energy projects within these states. This paper will provide a broad-spectrum view about the energy situation within Jammu and Kashmir and will highlight the current policies along with future strategies for the optimal utilization of renewable energy resources.     

Mapping the potential for decentralized energy generation based on renewable energy sources in the Republic of Croatia

There are regions in the Republic of Croatia (underdeveloped, devastated by war, depopulated, as well as islands and mountainous areas) which are still disconnected from the electricity network or where the current network capacity is insufficient. In addition, these regions have good renewable energy potential. Since the decentralized energy generation (DEG) covers a broad range of technologies, including many renewable energy technologies (RET) that provide small-scale power at sites close to the users, this concept could be of interest for these locations. This paper identifies the areas in Croatia where such systems could be applied. Consideration is given to geographical locations as well as possible applications. Wind, hydro, solar photovoltaic, geothermal, and biomass conversion systems were analyzed from a technological and economic point of view. Since the renewable energy sources (RES) data for Croatia are rather scarce, the intention was to give a survey of the present situation and an estimate of future potential for DEG based on RES. The energy potential (given as capacity and energy capability) and production costs were calculated on a regional basis and per type of RET. Finally, the RES cost–supply curves for 2006 and 2010 are given.     

Empirical determinants of renewable energy deployment: A systematic literature review

A large share of greenhouse gas emissions can be attributed to the energy sector. Renewable energy (RE) appears to be a mean to decarbonize economies. To fight global warming, which might have substantial impacts on ecosystems and economies, it is essential to understand the empirical determinants of RE deployment for public policy guidance and to foster future research. This paper aims to review the growing, though limited, body of literature that has emerged in the late 2000s to study the quantitative determinants of RE development at a country level. Results show that there is little consensus on the influence of the economic, environmental, and energy-related determinants predominantly studied. The other main determinants considered are regulatory, political, and demographic. Results are often tempered by the fact that authors use diverse measures of RE deployment and have a variety of frameworks. This paper ends with several recommendations to improve the comparability of future papers to enhance their potential to make credible public policy recommendations. More specifically, the recommendations concern the choice of a RE deployment indicator, the determinants considered for further exploration, and the methodologies adopted.

Potential and use of renewable energy sources in Croatia

The current share of renewable energy sources in electricity production in Croatia is very high, around 50%. Nevertheless it is expected that the share of renewables will have to rise and efficient strategies must be examined and adopted. The Croatian government has recognised the important role renewable energy sources could play in Croatian energy and electricity supply. The most important barrier for a wider deployment of renewables in energy production is their cost which is still above those of conventional energy sources. As the energy market is currently undergoing the process of liberalisation, support mechanisms that are compatible with an open market philosophy must be adopted. The characteristics of the Croatian power system, the expected consumption, growth and possible future role of renewables in energy and electricity production is presented. The current legislative framework relevant for renewables is analysed and discussed.     

Global analysis of the techno-economic potential of renewable energy hybrid systems on small islands

Globally, small islands below 100,000 inhabitants represent a large number of diesel based mini-grids. With volatile fossil fuel costs which are most likely to increase in the long-run and competitive renewable energy technologies the introduction of such sustainable power generation system seems a viable and environmental friendly option. Nevertheless the implementation of renewable energies on small islands is quite low based on high transaction costs and missing knowledge according to the market potential.Our work provides a global overview on the small island landscape showing the respective population, economic activity, energy demand, and fuel costs for almost 1800 islands with approximately 20 million inhabitants currently supplied by 15 GW of diesel plants. Based on these parameters a detailed techno-economic assessment of the potential integration of solar PV, wind power, and battery storage into the power supply system was performed for each island. The focus on solar and wind was set due to the lack of data on hydro and geothermal potential for a global island study. It revealed that almost 7.5 GW of photovoltaic and 14 GW of wind power could be economically installed and operated on these islands reducing the GHG-emissions and fuel consumption by approximately 50%. In total numbers more than 20 million tons of GHG emissions can be reduced by avoiding the burning of 7.8 billion liters of diesel per year. Cost savings of around 9 USDct/kWh occur on average by implementing these capacities combined with 5.8 GWh of battery storage. This detailed techno-economic evaluation of renewable energies enables policy makers and investors to facilitate the implementation of clean energy supply systems on small islands. To accelerate the implementation of this enormous potential we give specific policy recommendations such as the introduction of proper regulations.     

Promoting renewable energy sources for heating and cooling in EU-27 countries

In addition to public policies aimed at improving the energy efficiency of buildings, EU authorities have also promoted the use of Renewable Energy Sources for heating and cooling uses (RES H&C). This paper analyses the main policy measures implemented in EU-27 countries up to 2009: i.e. subsidies, tax incentives, financial support and feed-in tariffs. Twenty-three Member States (MSs) have developed some of these policy measures.     

A review of computer tools for analysing the integration of renewable energy into various energy systems

This paper includes a review of the different computer tools that can be used to analyse the integration of renewable energy. Initially 68 tools were considered, but 37 were included in the final analysis which was carried out in collaboration with the tool developers or recommended points of contact. The results in this paper provide the information necessary to identify a suitable energy tool for analysing the integration of renewable energy into various energy-systems under different objectives. It is evident from this paper that there is no energy tool that addresses all issues related to integrating renewable energy, but instead the ‘ideal’ energy tool is highly dependent on the specific objectives that must be fulfilled. The typical applications for the 37 tools reviewed (from analysing single-building systems to national energy-systems), combined with numerous other factors such as the energy-sectors considered, technologies accounted for, time parameters used, tool availability, and previous studies, will alter the perception of the ‘ideal’ energy tool. In conclusion, this paper provides the information necessary to direct the decision-maker towards a suitable energy tool for an analysis that must be completed.     

An econometric analysis of residential expenditures on energy conservation and renewable energy sources

Economic theory suggests that residential expenditures on energy conservation and renewable energy sources will be determined by the ability of households to purchase conservation inputs, their incentive to invest in conserving energy, the energy efficiency of existing homes and miscellaneous factors such as climate and age of the home-owner. Empirical analyses of energy-related expenditures reported on individual income tax returns confirm the importance of household income, energy price increases and climate conditions in determining energy conservation investments. Income tax credits are also found to have stimulated residential spending on conservation and renewable energy.     

A methodology for the electrical energy system planning of Tamil Nadu state (India)

In this paper, an energy planning optimisation procedure of a selected territory is illustrated and applied using an energy flow optimisation model. The developed approach takes into account various electricity generating options to meet the energy needs of various demand sectors. Energy saving techniques and hybrid technologies are considered and various scenarios are developed by assessing the contribution of renewable energy technologies over the planning period. The procedure aims to reduce the total actualised cost of energy generation over selected time horizon and predicts the additional installations required along with the existing facilities to meet the energy demand. At the same time the role of renewable energy technologies and of energy saving measures is evaluated by imposing suitable constraints on CO₂ emissions and primary energy sources exploitation. The procedure is applied to the territory of Tamil Nadu state (India) by considering different energy planning scenarios.     

A qualitative factor analysis of renewable energy and Sustainable Energy for All (SE4ALL) in the Asia-Pacific

This study assesses the factors responsible for the success and failure of renewable energy access programs in Bangladesh, China, Laos, Mongolia, Nepal, Sri Lanka, India, Indonesia, Malaysia, and Papua New Guinea. Based on 441 research interviews over the course of four years, site visits to 90 renewable energy facilities, and focus groups with almost 800 community members in 10 countries, this study develops a series of overarching qualitative factors that correlate with programs that met their targets, sometimes ahead of schedule, and produced measurable benefits exceeding costs. The inverse of these factors is associated with programs that did not meet their targets, were behind schedule, and/or produced measurable costs exceeding benefits. It concludes by offering 10 lessons for energy analysts and development practitioners concerning appropriate technology, income generation, financing, political leadership, capacity building, programmatic flexibility, marketing and awareness, stakeholder engagement, community ownership, and technical standardization.     

State renewable energy electricity policies: An empirical evaluation of effectiveness

Over the past decade, state governments have emerged as US energy policy leaders. Across the country, states are adopting policy instruments aimed at carbon mitigation and renewable energy deployment. One of the most prevalent and innovative policy instruments is a renewable portfolio standard (RPS), which seeks to increase the share of renewable energy electrification in the electricity market. This analysis evaluates the effectiveness of state energy programs with an empirical investigation of the linkage between state RPS policy implementation and the percentage of renewable energy electricity generation across states. We use a variant of a standard fixed effects model, referred to as a fixed effects vector decomposition, with state-level data from 1998 to 2006. Results indicate that RPS implementation is not a significant predictor of the percentage of renewable energy generation out of the total generation mix, yet for each additional year that a state has an RPS policy, they are found to increase the total amount of renewable energy generation. These findings reveal a potentially significant shortcoming of RPS policies. Political institutions, natural resource endowments, deregulation, gross state product per capita, electricity use per person, electricity price, and the presence of regional RPS policies are also found to be significantly related to renewable energy deployment.     

An assessment of exploiting renewable energy sources with concerns of policy and technology

In recent years, the Taiwanese government has vigorously promoted the development of renewable energy to engage the challenges of gradual depletion of fossil fuels and oil, as well as the intensification of the greenhouse effect. Since the Sustainable Energy Policy Principles were announced in 2008, Taiwanese government has declared that the development of renewable energy should take into account goals that pertain to energy, the environment, and the economy (3E goals). This study aims to assess the 3E goals and renewable energy sources regulated by the Renewable Energy Development Bill that passed in 2009. The fuzzy analytic hierarchy process (FAHP) is used to resolve the multi-goal problem for achieving our research purposes. That is, this research attempts to reveal the suitable renewable energy sources for the purposes of meeting the 3E policy goals. The results first show that environmental goal is the most important to the development of various renewable energy technologies in Taiwan, followed by the economic and energy goals. Additionally, hydropower, solar energy, and wind energy would be the renewable energy sources utilized in meeting the 3E policy goals.     

Technical change dynamics: evidence from the emerging renewable energy technologies

This paper explores the respective contributions of the effects of learning and returns to scale in the capital costs reduction pattern experienced by renewables. Causality analysis and econometric estimation of learning curves are performed on two emerging renewable energy technologies, namely PV and wind. Learning effects appear as an essential driving force, a result which concurs with the widely acknowledged importance of experience in technical progress inherent to economic growth. The existence of non-constant and flexible returns to scale are further highlighted. Their effect on diffusion dynamics is shown to be potentially considerable, particularly at the outset of innovation deployment. However, returns to scale are suggested to be constant in the long term. Institutional commitment in supporting innovation therefore seems justified, both on the basis of the occurrence of learning effects and diseconomies of scale. These findings appear to be essential to the dynamics of innovation diffusion and market structure.     

Global warming and renewable energy sources for sustainable development in Turkey

Turkey, with its young population and growing energy demand per person, its fast growing urbanization, and its economic development, has been one of the fast growing power markets of the world for the last two decades. It is expected that the demand for electric energy in Turkey will be 300 billion kWh by the year 2010 and 580 billion kWh by the year 2020. Turkey is heavily dependent on expensive imported energy resources 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. Turkey's geographical location has several advantages for extensive use of most of these renewable energy sources. This article presents a review of the potential and utilization of the renewable energy sources in Turkey.
