Geothermal energy could be potentially transformational for our power grids, as we saw in our last video. But you and I can also get in on the act by drawing our own domestic heating from beneath our gardens (or communal gardens if you live in an apartment block). The technology is called a Ground Source Heat Pump. They’ve been around for a while but they are growing very quickly in popularity and may prove to be one of the lynch pins in helping us get to carbon neutrality by 2050.
