Honestly surprised Iceland doesn't rely more on geothermal, the entire country is a volcano! I had expected a 70-30 split in the other direction
most people from abroad do, but most of that geothermal goes to home heating and not power generation too.
Geothermal is fantastic for heating. Speaking as an Icelander, we have so much hot water in Reykjavík that we even use the residue to keep our pavements clear of ice in winter. Pipes under the sidewalks carry exiting geothermally heated water from nearby houses. It's great technology and has served us well.
