Global demand for energy shows no signs of slowing; carbon dioxide emissions keep surging to new records; and political uprisings, natural disasters and volatile energy markets put the security of energy supplies to the test.More than ever, the need for a fundamental shift to a cleaner and more reliable energy system is clear. What technologies can make that transition happen? How do they work? And how much will it all cost?

The 2012 edition of Energy Technology Perspectives (ETP), to be released in June, answers these and other fundamental questions. Its up-to-date analysis, data and associated website are an indispensible resource for energy technology and policy professionals in the public and private sectors.
