Technology roadmap: solar heating and cooling.

Résumé

The objective of this roadmap is to promote the global uptake of solar heating and cooling technology in OECD countries as well as in developing countries and transition economies. Solar energy conversion consists of a large family of different technologies with a broad range of applications. Solar technologies can deliver heat, cooling, natural lighting, electricity and fuels, but this roadmap concentrates on the use of solar energy in heating and cooling applications.
The solar heating and cooling (SHC) roadmap outlines a pathway for solar energy to supply almost one sixth (16.5 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 global energy demand, the roadmap envisages that if concerted action is taken by governments and the industry, solar energy could annually produce over 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.
