A new book on Climate Impacts on Energy Systems, Key Issues for Energy Sector Adaptation  was launched by ESMAP and the World Bank’s Global Expert Team on Climate Adaptation in Washington DC on February 28, 2011. The book presents an overview of the impact of climate change on the energy sector and it provides solutions for managing these impacts.  It focuses on energy sector adaptation, rather than mitigation that has been a key focus of the energy sector. The book draws on available scientific and peer reviewed literature in the public domain and examines the issues from a developing country perspective.
