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 …
