Planning, operating, and policy making in the electric utility and natural gas sectors involves important trade-offs among economic, social, and environmental criteria. These trade-offs figure prominently in ongoing debates about how to meet growing energy demands and how to restructure the world's power industry. Energy Decisions and the Environment: A Guide to the Use of Multicriteria Methods reviews practical tools for multicriteria (also called multiobjective) decision analysis that can be used to quantify trade-offs and contribute to more consistent, informed, and transparent decision making. These methods are designed to generate and effectively communicate information about trade-offs; to help people form, articulate, and apply value judgments in decision making; and to promote effective negotiation among stakeholders with competing interests. Energy Decisions and the Environment: A Guide to the Use of Multicriteria Methods includes explanations of a wide range of methods, tutorial applications that readers can duplicate, a detailed review of energy-environment applications, and three in-depth case studies.

This book discusses analytical methods for energy sector planning in developing countries. It addresses such topics as energy balances, the Reference Energy System, and approaches to the evaluation of macroeconomic impacts of energy sector decisions.

Over the past decade almost all developing countries have established energy planning activities in response to the grave problems that have arisen as a result of the drastic increase in energy prices, of the burden of energy related investment debt service, and of the problems of deforestation. Although the insti tutional and organizational responses are quite varied, it is largely engineers and economists who have been called upon to provide the necessary analytical capability to support policy decisions in the energy area. However, as evidenced by the recent participants in the Energy Management Training Program (EMTP), many of the analytical techniques now regarded as appropriate go beyond the usual background of those who are now assigned to such tasks. Indeed, this monograph is based on the material presented in the first *part of the course, whose purpose is to bring the often diverse group to some common ground. Some of the material, such as Chapter 4 on the basics of energy pricing, is intended primarily for engineers. Other sections, such as Chapter 2 on energy balances, is primarily a vehicle for a discussion of the problems of units and differences in approach by different international bodies. The intent, then, is to provide in a single work a primer on a large number of different analytical tools.

Energy plays a vital role in economic and social development. The analysis of energy issues and policy options is therefore a vital area of study. This book presents a hierarchical modelling scheme intended to support energy planning and policy analysis in developing countries. The authors introduce the concept of 'Integrated National energy Planning' (INEP), and examine the spreadsheet models, optimization models, and linear planning models which energy planners use. Environmental considerations are also introduced into the analysis. Techniques are then applied to two important energy subsectors, electricity and fuelwood, before problems of integration and policy implementation are discussed. Throughout the book, the authors examine actual practice in developing countries. Illustrative case material is drawn from Egypt, West Africa, Sudan, Pakistan, Colombia, India, Sri Lanka and Morocco. This book will be of interest to students and practitioners of energy planning, and to those concerned with the wider development implications of energy policy.

The novelty of this work is the fact that it introduces a rigorous and objective economic perspective of current renewable energy support mechanisms and an empirical analysis of the strengths and weaknesses of these mechanisms, which is much needed in a debate often dominated by widespread misconceptions. The economic rationale for renewable energy is straightforward: the optimum amount of renewable energy for grid-connected generation is given by the intersection of the renewable energy supply curve with the avoided cost of thermal electricity generation. The proposed analytical framework: (i) differentiates and illustrates trade-offs among local, regional, and national impacts, in the short and long run; (ii) captures distributional impacts; and (iii) captures externalities and compares alternative projects based on equivalent output and cost. Accordingly, the study advocates for the need to get the economic, financial, and institutional basics right for the deployment of renewable energy. The study s integration of renewable energy subsidies with fossil subsidies is another novel and important contribution. This allows important comparisons. For example, to reduce carbon intensity in developing country economies, is it more efficient to deploy renewable energy or implement alternative options, such as eliminating subsidies on fossil fuels? The work is based on case studies of Vietnam, Indonesia, Sri Lanka, South Africa, Tanzania, Egypt, Brazil, and Turkey, selected to provide a representative sample of countries with different energy endowments (coal, natural gas, and hydro-based systems) and policy incentives (from feed-in tariffs to auctions). Along the way, the incremental cost of renewable energy is compared with the average cost of generation. The selection and design of support mechanisms in turn determines the impacts on the budget and residential consumers. The main lessons emerging from the case studies are that successful renewable energy policies: Will only be effective once the state-owned utilities who are the buyers of grid-connected renewable energy are themselves in good financial health Need to be grounded in economic analysis and accompanied by the application of market principles to ensure economic efficiency Require a sustainable, equitable, and transparent recovery of incremental costs"
