[en] This paper presents the historical development of Turkey's electricity power sector, the efforts for introducing competition in the power industry in Turkey, and the concerns regarding restructuring in Turkey. The contribution of the hydropower energy potential in Turkey to the reconstruction of the electricity structure in Turkey is also investigated. Then, among the 25 hydrological basins in Turkey, the Eastern Black Sea Basin located in the northeast of Turkey, which has great advantages from the view point of small hydropower potential or hydropower potential without storage, is chosen as the case study to carry out some investigations concerning its potential and to analyze the contribution of the private sector (the corporate body) in regard to the development of hydro potential in this basin within the scope of the 4628 Electricity Market Law. With this law, concerning the restructuring of the electricity market, private sector investments in this segment have increased. In total, 1524 hydroelectric power projects with 22 360 MW installed capacity has been implemented until January 22nd, 2009 and this figure is continuously rising. (author)
[en] Exploratory scenarios for the power sector in Nigeria are analysed in this paper using possible pathways within the Nigerian context and then compared against the Government's power expansion plan in the short to medium term. They include two fossil-fuel (FF and CCGT) and two sustainable-development-driven scenarios (SD1 and SD2). The results from the FF scenarios indicate this is the preferred outcome if the aim is to expand electricity access at the lowest capital costs. However, the annual costs and environmental impacts increase significantly as a consequence. The SD1 scenario, characterised by increased penetration of renewables, leads to a reduction of a wide range of environmental impacts while increasing the annual costs slightly. The SD2 scenario, also with an increased share of renewables, is preferred if the aim is to reduce GHG emissions; however, this comes at an increased annual cost. Both the SD1 and SD2 scenarios also show significant increases in the capital investment compared to the Government's plans. These results can be used to help inform future policy in the Nigerian electricity sector by showing explicitly the range of possible trade-offs between environmental impacts and economic costs both in the short and long terms.

The Renewable Energy Country Attractiveness Indices publication scores and comments on various technologies, including: on-shore wind, off-shore wind, solar PV, solar CSP, biomass, and geothermal.
[en] The objective of this paper is to investigate the co-movement of food prices and the macroeconomic index, especially the oil price, by principal component analysis to further understand the influence of the macroeconomic index on food prices. We examined the food prices of seven major products: eggs, meat, milk, oilseeds, rice, sugar and wheat. The macroeconomic variables studied were crude oil prices, consumer price indexes, food production indexes and GDP around the world between 1961 and 2005. We use the Scree test and the proportion of variance method for determining the optimal number of common factors. The correlation coefficient between the extracted principal component and the macroeconomic index varies between 0.87 for the world GDP and 0.36 for the consumer price index. We find the food production index has the greatest influence on the macroeconomic index and that the oil price index has an influence on the food production index. Consequently, crude oil prices have an indirect effect on food prices. (author)
[en] The Dutch Air Quality Collaboration program (NSL) is introducing a new approach to complex issues. This programmatic approach may offer a solution, but is still relatively new in spatial policymaking. What can we learn about the success and failure aspects of programs from the approach at NSL?.
[nl]Het Nationaal Samenwerkingsprogramma Luchtkwaliteit (NSL) introduceert een nieuwe aanpak voor complexe problemen. Deze programmatische aanpak kan hiervoor een oplossing zijn, maar is relatief nieuw in de ruimtelijke beleidspraktijk. Wat leert de aanpak bij het NSL ons over succes- en faalfactoren van programma's?.
[en] In 2003, the IAEA published the Handbook on Nuclear Law (the 2003 Handbook), which emphasized that the safe and peaceful uses of nuclear energy in any State can only be ensured with the promulgation and implementation of an effective national legal framework to govern this technology. The IAEA has long been involved in providing assistance to its Member States in developing these frameworks, and demand for such assistance has increased dramatically. Since publication of the 2003 Handbook, requests for IAEA legislative assistance have - if anything - been even more numerous, in large part due to the fact that over sixty Member States that currently do not utilize nuclear energy for the production of electrical power have recently expressed interest in pursuing this option. The current nuclear laws in many of these States are limited to non-power uses of ionizing radiation, such as those utilizing radiation sources for medical, agricultural and industrial purposes. If these States move toward nuclear power development, they will need to adopt legislation consistent with the various relevant international legal instruments covering the field (such as the Convention on Nuclear Safety and the Convention on the Physical Protection of Nuclear Material, among others) and with relevant voluntary guidance documents developed under the aegis of the IAEA. The 2003 Handbook has already made an important contribution to enhancing national capabilities to develop the necessary legal frameworks by setting out the general scheme of nuclear law. However, a number of important developments in nuclear law have occurred since its publication. These developments are discussed in the present volume. Also, over the past six years, representatives of many Member States receiving IAEA legislative assistance have suggested that it would be valuable to develop model texts of legislative provisions covering the key elements needed in a national nuclear law. The present volume provides such model texts, recognizing that they provide only a starting point and basic outline of necessary provisions that will need to be shaped to be consistent with each State's national approach to legislative drafting, cultural and social norms, economic structure, and the nature of its nuclear programme. It contains the most up to date and comprehensive guidance for Member States in enhancing their legal and regulatory frameworks for nuclear energy development
[en] CO2 capture and storage can ensure that stringent climate change mitigation targets are achieved more cost-effectively. However, in order to ensure a substantial role for CCS, deployment of CCS is required on a significant global scale by 2020. Currently, the CDM is the only international instrument that could provide a financial incentive for CCS in developing countries. In December 2010 it was decided that CCS could in principle be eligible under the CDM, provided a number of issues are resolved, including non-permanence, liability, monitoring and potential perverse outcomes. The latter issue relates to the concern that that CCS projects could flood the CDM market, thereby crowding out other technologies that could be considered more sustainable. This report, therefore, aims to quantify the possible impact of CCS on the CDM market, in order to assess the relevance of the CDM market objection. However, the analysis in the report is also valid for the role of CCS in other types of international support mechanisms. The first result of this study is a marginal abatement cost curve (MAC) for CCS in developing countries for 2020. Based on existing MAC studies, the IEA CCS Roadmap and an overview of ongoing and planned CCS activities, we compiled three scenarios for CCS in the power, industry and upstream sector, as shown below. The major part of the potential below $30/tCO2eq (70 - 100 MtCO2/yr) is in the natural gas processing sector. Using the MACs for the CDM market, we estimate the economic potential for CCS projects to be 4-19% of the CDM credit supply in 2020. The potential impact inclusion of CCS in the CDM may have is assessed by using several possible CER supply and demand scenarios, as well as scenarios related to market price responsiveness and the role of CDM in the post-2012 carbon market. The impact is estimated to be between $0 and $4 per tonne of CO2-eq, with three out of four scenarios indicating the lower part of this range.
[en] In view of having a still unexploited potential of natural resources available for clean energy and the possibility of using the regional electricity market in Central America, Honduras has several potential energy sources. The growing dependence on oil and the imminent increase in international prices of fossil fuels, coupled with the necessity of changing the energy sector arrangement, the State of Honduras has taken the lead for the development of a long-term sustainable energy policy. This energy policy must be able to develop various energy sources and guide both, the government and the private sector, to the planning and development of alternative energy sources and sustainable growth of the Honduran economy. In this paper, the various energy diagnoses and the potential for changing the Honduran energy mix are presented, as well as the investment required for sustainable management of the energy sector. Furthermore, the objectives of the energy policy and plan up to the year 2030 are presented, outlining the investment possibilities for the energy sector development, showing their costs and timeframes. - Research Highlights: → This paper shows the development of a long-term energy policy for Honduras. → The various diagnoses of the energy sector in Honduras are shown, considering the use of wood, biomass, biofuels, electricity, transportation, hydrocarbons and rural electrification. → The most relevant results of the analysis of energy forecasting are shown, for which the LEAP software was used. → The objectives of the energy policy and plan up to the year 2030 are presented, outlining the investment possibilities for the energy sector development, showing their costs and timeframes.
[en] have examined a synergy effect between electricity and gas services in the US electric utility industry. They have compared electricity-specialized firms with diversified utility firms in their financial performance and corporate value. A problem of their study is that it has not empirically measured the operational performance of the electric utility firms. As an extension of the preceding study, this research investigates the operational performance of 104 US electric utility firms (1990-2004) by fully utilizing DEA (Data Envelopment Analysis). This study finds the three new policy implications. First, the synergy effect has not existed in the operational performance of diversified utility firms before and after the deregulation on the US electricity markets. Thus, core business concentration is more effective for electric utility firms than corporate diversification to enhance their operational performance under the current US deregulation policy. Second, the operational performance has had an increasing trend until 1996 and a decreasing trend after 1996. Thus, the US deregulation policy has been influential on their operational performance. Third, the enhancement in operational performance of electric utility firms has improved their financial performance. The improvement in financial performance has increased their corporate value. Thus, this study finds the business causality among operational performance, financial performance and corporate value in the US electric utility industry. - Research Highlights: →The synergy effect has not existed in the operational performance of diversified utility firms before and after the deregulation on the US electricity markets. →Core business concentration is more effective for electric utility firms than corporate diversification to enhance their operational performance under the current US deregulation policy. →The operational performance has had an increasing trend until 1996 and a decreasing trend after 1996. →The US deregulation policy has been influential on their operational performance. →The enhancement in operational performance of electric utility firms has improved their financial performance. →The improvement in financial performance has increased their corporate value.
