[en] Glancing at the actual development of environmental policy in the European Community over the past three decades, one sees a picture that seems to be very much in contradiction with the advise of neo-classical economics. With the support of the Council, the European Commission has been developing a Community environmental policy from 1972 on. Principal instruments of this Community environmental policy have been directives that require harmonisation of environmental standards for similar industries in the various Member States. In its most strict sense of full harmonisation, this policy would imply uniform environmental standards. Industry would then use the environment with the same intensity independent of where producers are situated in the European Community. The consequence of a harmonised approach would be that in countries where environmental quality is scarce, pollution per unit of output would be as high or low as it is in countries where environmental quality is relatively abundant. This dissertation has been inspired by this apparent discrepancy between the advice from economic theory and the practice of the Community environmental policy. A first question, which is the main issue of this book, is whether the observation of a discrepancy is correct or perhaps a faulty perception. A next question is whether an explanation can be given for the discrepancy in so far as it turns out to exist. These questions are analysed on the bases of a selection of directives aimed at or having a strong impact on polluting emissions by stationary point sources. The first issue addressed is to determine what economic theory says exactly about the international harmonisation of environmental standards. A second question concerns the legal base for the environmental secondary legislation that was chosen by the European Institutions. A third question concerns the reasons for harmonisation of environmental standards that are used. A fourth question concerns the actual level of harmonisation of environmental standards in the European Community. The basic question is whether the level of harmonisation in EU environmental legislation is in correspondence with the conclusions of neo-classical economic theory
[en] Economic processes generate a variety of material flows, which cause resource problems through the depletion of natural resources and environmental issues due to the emission of pollutants. This thesis presents an analytical method to study the relationship between the monetary economy and the 'physical economy'. In particular, this method can assess the impact of structural change in the economy on physical throughput. The starting point for the approach is the development of an elaborate version of the physical input-output table (PIOT), which acts as an economic-environmental accounting framework for the physical economy. In the empirical application, hybrid-unit input-output (I/O) tables, which combine physical and monetary information, are constructed for iron and steel, and plastic products for the Netherlands for the years 1990 and 1997. The impact of structural change on material flows is analyzed using Structural Decomposition Analysis (SDA), whic specifies effects such as sectoral shifts, technological change, and alterations in consumer spending and international trade patterns. The study thoroughly reviews the application of SDA to environmental issues, compares the method with other decomposition methods, and develops new mathematical specifications. An SDA is performed using the hybrid-unit input-output tables for the Netherlands. The results are subsequently used in novel forecasting and backcasting scenario analyses for the period 1997-2030. The results show that dematerialization of iron and steel, and plastics, has generally not occurred in the recent past (1990-1997), and will not occur, under a wide variety of scenario assumptions, in the future (1997-2030)
[en] This study focuses on the processes through which the rules and regulations that govern European electricity markets - and inherently, their integration process - are established. So far, European policy makers have largely followed a 'trial-and-error' approach to finding an appropriate regulatory mode (process) for dealing effectively with market integration issues. This unstructured approach to regulatory mode selection leads to several problems: - Today's trial-and-error strategy of shifting from one regulatory mode to another is time-consuming. - In the regulatory mode selection process, certain key principles of good governance are insufficiently considered. - European regulatory processes are experienced as vague, intransparent, and illegitimate by 'outside' stakeholders. This study develops a 'structured approach to regulatory mode decision-making' (STARMODE) based on the theory of decision modelling in policy management and a case study exploring three key market integration issues in the field of electricity markets: interconnector investment, congestion management and market transparency. The main objective is to present a systematic and comprehensive framework for analysing and improving regulatory mode decision-making in the context of the European Union, focusing on electricity market integration. The STARMODE approach is generally applicable to (and relevant for) European market integration issues in industries characterized by a natural monopoly and/or an essential service. The approach may also contribute to national regulatory mode decision-making and multi-state decision-making in other continents.
[en] The social impact of Goiania nuclear accident is analysed from a semiotic investigation upon papers issued on popular magazines, newspapers and scientific periodicals. Also the communication of Science Information is discussed through three basic models: diffusionist, bibliometric and cultural perspectives. Divulgation and diffusion process of scientific information are reviewed on the bases of theory of representation and theory of sign. The relationship between energy and society is discussed though a compared analysis upon the information sources available to public and scientific community. (author)
[en] This paper tests the Environmental Kuznets Curve hypothesis for four local (SOx, NOx, CO, VOC) and two global (CO2, GHG) air pollutants. Using a new panel data set of thirty OECD countries, the paper finds that the postulated inverted U-shaped relationship between income and pollution does not hold for all gases. A meaningful Environmental Kuznets Curve exists only for CO, VOC and NOx, where for CO2 the curve is monotonically increasing. For GHG there is indication of an inverted U-shaped relationship between income and pollution, but still most countries are on the increasing path of the curve and hence the future development of the curve is uncertain. For SOx it was found that emissions follow an U-shaped curve. Based on the empirical results, the paper concludes that the Environmental Kuznets Curve does not hold for all gases, it is rather an empirical artefact than a regularity.
[en] In response to the 2011 Fukushima nuclear disaster in Japan, France ordered stress tests of its nuclear plants while Germany announced its nuclear exit by 2022. Given that both countries benefitted from nuclear energy with a relatively low risk of a disaster, this divergence is puzzling. Yet France and Germany’s reactions were not ad hoc reactions; they were shaped by their post-war experiences and previous anti-nuclear mobilizations. Fukushima merely offered a political opportunity for the effective vocalization of antinuclear dissent, and ultimately the permeability of governing institutions determined each country’s response. In order to explore this argument, this paper will examine the issue's coverage predominately within one French newspaper, Le Monde, and one German newspaper, Suddeutsche Zeitung, from 11 March to 18 June 2011 to gain insight of contemporary political opportunities and elite consensus as well as how meaning was being constructed and consumed by the public on this issue.

[en] Today, electricity is very important in our life for our activities, lighting, factories, air conditioning, irrigation, refrigerators, etc. utility will be subjected to a lot of problems. So, electric utilities search for a method to provide customers with the electric energy demand with a reasonable level of reliability and economically as possible. Demand-side management is an important consideration for electric power utilities, in order to control using of electric power. Demand-Side Management (DSM) programs consist of the planning, implementing and monitoring the activities of electric utilities which are designed to encourage consumers to modify their level and pattern of electricity usage. The goal of this thesis is to determine the impact of DSM on the power system load curve and on the power system reliability. Different DSM programs will be applied on the power system load curve of IEEE Reliability Test System (IEEE-RTS). Valley Filling method, Energy Conservation method, Peak Clipping method, Load Shifting method and Load Building method will be used to evaluate their effect on the hourly load curve. Different DSM will be applied on the Egyptian will be used to evaluate their affection the hourly load curve. Different DSM program will be applied on the Egyptian electricity power system to determine the effect of DSM programs (only four methods) on maximum annual day load profile and determine the effect of DSM on the total system cost and planning reserve margin.In this study, MESSAGE program will be used to calculate total system cost of the Egyptian electric power system which consists of 89 generation stations. The total system cost (fixed, variable and investment cost) will be calculated for the Base Case, then DSM programs will be applied (Energy Conservation, Valley Filling, Peak Clipping, Load Shifting and) on the Egyptian electric power system in each year for all cases. Also planning reserve margin will be calculated in each year for the base case and with DSM programs. Planning reserve margin will be calculated as a percentage of the total installed capacity. Average annual reserve margin will be calculated for each case of the plan. Also, average growth rate of peak load will be calculated for each case of the plan. Total capacity added in each year will be calculated for Base Case and four DSM programs of the Plan
[en] This report presents a comparative study of long-term energy demand and potential greenhouse gas emissions projections from energy demand and supply sectors in Bangladesh covering the period 2000 to 2020. The study was conducted employing the IAEA's tool ENPEP- BALANCE model. This study presents a reliable energy system plan with minimal carbon emission for the country. Primary energy demands distributed by energy carriers and electricity demand have been projected based on macro-economic growth scenarios constructed for national energy policy of 1996. The conservation of indigenous energy resources was emphasized to build a long-term secured energy supply system. The potential energy supply options including nuclear energy and prospective greenhouse gas mitigation options were analyzed
[en] This thesis is dedicated to the evaluation of environmental policies in the context of climate change. Its objectives are twofold. Its first part is devoted to the development of potent instruments for quantitative impact analysis of environmental policy. In this context, the main contributions include the development of a new computable general equilibrium (CGE) model which makes use of the new comprehensive and coherent World Input-Output Dataset (WIOD) and which features a detailed representation of bilateral and bisectoral trade flows. Moreover it features an investigation of input substitutability to provide modellers with adequate estimates for key elasticities as well as a discussion and amelioration of the standard base year calibration procedure of most CGE models. Building on these tools, the second part applies the improved modelling framework and studies the economic implications of environmental policy. This includes an analysis of so called rebound effects, which are triggered by energy efficiency improvements and reduce their net benefit, an investigation of how firms restructure their production processes in the presence of carbon pricing mechanisms, and an analysis of a regional maritime emission trading scheme as one of the possible options to reduce emissions of international shipping in the EU context.
[en] In this thesis, I address four distinct - yet closely linked - research questions related to the adoption of solar energy technologies in East Africa, which will be summarized in the following section. Chapter 2 starts with an analysis of the history, status and prospects of solar energy markets in Kenya and Tanzania, and a comparison of both countries. Chapter 3 investigates the main determinants of solar home system (SHS) adoption in Kenya, and lighting fuel choices among Kenyan households. Chapter 4 examines the cost of (and potential for) large-scale, grid-connected solar PV adoption in Kenya, and Chapter 5 looks at the influence of financing costs on the economics of solar PV on a global level. With my research I therefore contribute to the policy debate surrounding the African energy challenge by looking at two countries in particular, namely Kenya and Tanzania. I have chosen this geographic focus deliberately, as both countries - while well-endowed with sunshine - at present use only very little solar energy. Thus, while the practical focus on East Africa in three of the four chapters implies that the wider African energy challenge is not tackled head on, many of the findings and conclusions from the study of Kenya and Tanzania are in my view transferable to other countries in Africa, and probably even beyond that continent. In conducting research on the solar energy markets of East Africa over the past five years (2009-2014) I have certainly learnt that this continent does not offer the easiest research environment, and a clear focus on a small set of countries and only one renewable energy technology has been very important. Rigorous, high-quality research requires good information, such as data and statistics, as well as appropriate methods; and while the latter are in good supply, the former are painfully lacking for many aspects of life in East Africa. This poses a major challenge for (quantitative) research and has greatly impacted what I could and could not do in my own work. The focus of this thesis is on solar energy technologies, as these have progressed most rapidly in recent years and as the (physical) potential to use the sun's energy is especially large in (East) Africa (Mandelli et al., 2014). Furthermore, solar energy technologies (particularly solar photovoltaics, or solar PV) have already been adopted on a larger scale in many developing countries in Africa and elsewhere (as well as developed countries, where they are being used to an even larger scale). For my research, this means that there were at least some data, history of market development, technology policies and evidence from previous research to work with. The overall contribution of my work is two-fold: First, I address specific research questions of relevance to both researchers and policymakers; and second, I do this in the context of a continent that is in many ways under-researched. According to Das et al. (2013) only around 3% of peer-reviewed papers in leading economics journals deal with sub-Saharan Africa, despite the fact that it accounts for some 12% of the global population (World Bank, 2010). In this context, the potential and future role of solar energy technologies for African development is one important aspect that is not yet fully understood. Helping to address this knowledge gap and advancing the knowledge frontier consequently seems of great relevance for informed policy decisions on both sustainable development and climate change mitigation.
