As the world looks to the greening of economies to create new industries and jobs, protect the climate and environment and secure domestic energy supplies, we need effective policies more than ever. The rapid scaling-up of renewable energy deployment is a fundamental element of this process. Feed-in tariffs - laws that provide a premium rate (tariff) over a fixed period of time for each unit of electricity fed into the grid - are one of the most cost-effective policy tools for accelerating the transition to a more sustainable energy system. Despite their increasingly widespread use, the effectiveness of feed-in tariffs can be hampered by poor design and inadequate implementation. This book, from authors who have spent years working on feed-in tariff design and advocacy, covers: -An introduction to feed-in tariffs, how they work, and developments in key countries around the world (including in Europe, Asia, Africa, Australia, North and South America) - An exploration of technical and social issues - An investigation of effective design, and other support schemes - A blueprint for campaigning for feed-in tariffs - A compilation of further resources for those wishing to green their economy Written in a clear, practical style, this is a must-read for any policymakers, businesses, investors, campaigners, academics and anyone concerned with creating successful and sustainable energy policy.
