Can renewables be used for heating?

Half of all the energy we use globally goes on heating and
cooling. We need heating for all sorts of things; from keeping
our homes warm to industry which needs super high temperatures.
At the moment, the heat we use is mostly powered by polluting
fossil fuels, a huge driver of climate change. But can renewables
deliver the high temperatures and a constant supply which are so
vital? In this episode we visit the world's first
commercial-scale sand battery in Finland and find out how it’s
using renewables to heat 100 homes and a public swimming pool.
