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.

The solar heating and cooling (SHC) roadmap outlines a pathway for solar energy to supply almost one sixth (18 EJ) of the world’s total energy use for both heating and cooling by 2050.  This would save some 800 megatonnes of carbon dioxide (CO2) emissions per year; more than the total CO2 emissions in Germany in 2009. While solar heating and cooling today makes a modest contribution to world energy demand, the roadmap envisages that if concerted action is taken by governments and industry, solar energy could annually produce more than 16% of total final energy use for low temperature heat and nearly 17% for cooling.  Given that global energy demand for heat represents almost half of the world’s final energy use – more than the combined global demand for electricity and transport – solar heat can make a significant contribution in both tackling climate change and strengthening energy security.
