1 July 2010: The International Energy Agency (IEA) has published the 2010 edition of its series “Energy Technology Perspectives,” which aims to inform decision makers on the technological actions necessary to realize the energy revolution IEA says is necessary to reduce carbon dioxide emissions by 50% by 2050 (compared to 2005 levels).

Specifically, the report: identifies which technologies will be most necessary on a regional basis; carries out a sectoral analysis of technological challenges and opportunities, and how to best exploit them with targeted policies; and explores methods for transition to lower carbon societies. Additionally, the report offers suggestions for overcoming key technical and political obstacles to the widespread deployment of six important technology areas: carbon capture and storage (CCS); nuclear power; renewable energies; power generation efficiency and fuel switching; end-use fuel switching; and end-use fuel and electricity efficiency, which is expected to provide the most significant benefits of all.

Although the report estimates that halving 2005 emissions by 2050 will cost USD 46 trillion, these investments could realize fuel savings alone of over USD 112 trillion over the same period. [IEA Press release] [Power Point Presentation for the Press] [Publication Webpage] [Executive Summary]
