The International Energy Agency (IEA) is leading the development of a series of roadmap for some of the most important energy technologies.  Roadmaps achieve consensus on low-carbon energy milestones, priorities for technology development, policy and regulatory frameworks, investment needs and public engagement.  As such, roadmaps can provide solid analytical footing that enables national policy makers and industry to develop specific technologies.  12 technology specific roadmaps have now been completed covering both energy supply and demand technologies.
