Why don’t we use more geothermal energy?

Geothermal energy is renewable, reliable and powerful. So, why is
most of it untapped? That’s what our listener, Anna in the UK,
wants to know. Full disclosure, she’s a geologist and is
thoroughly perplexed by the lack of uptake. Geothermal is
renewable, reliable and abundant and yet, less than 1% of the
world’s energy is generated from it. Host Graihagh Jackson hears
about a team in Iceland who hope to "super-charge" geothermal
power by drilling directly into volcanic magma. And she travels
to Germany to visit Vulcan Energy, a company which is combining
geothermal with extracting one of the world's most sought-after
metals: Lithium. Plus, our reporter in Indonesia tells Graihagh
about local opposition to some geothermal power plants. The
programme was first broadcast in 2024. Got a question you’d like
