Energy use for heating is about half of the world's energy demand and 40% of global CO2 emissions. Currently, most of the world's heating comes from fossil fuels and traditional biomass. Modern renewable heat consumption supplies only slightly over 10% of the world's heat, and it is not increasing fast enough to keep up with global decarbonisation targets.
In this video, we take a rooftop tour of a photovoltaic thermal technology, Sunovate, that cools down solar panels to make them more efficient, and uses that heat for heating buildings or industrial processes.
Check out the Just Have a Think Video on this same technology here:
