What energy savings are achievable if there were a more rapid
uptake of advanced technologies and practices to improve energy efficiency, and what are the costs and benefits of doing so?
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.
