Turning waste into power

Food waste from hotels and the heat from computers are being used to provide new sources of energy. In the fight against climate change, it is of vital importance to find new ways of making our energy go further. We visit Goa in India, to hear how food waste digesters - that turn waste into gas for cooking – are springing up everywhere. And in server centres around the world, we explore how the heat generated by running the internet is being re-used by local neighbourhoods.
