Paolo Frankl, Head of IEA's Renewable Energy Division, commented: «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, The IEA's Solar Heating and Cooling Roadmap outlines how best to advance the
global uptake of solar heating and cooling (SHC) technologies, which, it
notes, involve very low levels of greenhouse - gas emissions.
