This book addresses energy-related issues in light of the options available to the European and Mediterranean countries. The articles attempt to identify and analyse the economic, environmental, societal and regional security issues that may emerge from those options. It is clear that a coherent energy strategy is required, addressing energy supply and demand, security of access, financial issues, market dynamics, and also taking into account the whole energy lifecycle including fuel production, transmission and distribution. In the short term, the aim should be to achieve higher energy efficiencies and increased supply from local energy sources, in particular renewable energy sources. In the long term, redesign of life styles, further increase of alternative energy sources and shift to new energy technologies and carriers is expected to contribute to solve or alleviate the problems generated by declining availability of fossil fuels. In this volume, energy experts provide background information and a detailed discussion of all these issues and strategies.
