- jolmg 7y agoI didn't know that most geothermal energy was from fission, but as the article says, not all geothermal energy comes from fission. There's also the release of heat as the outer core solidifies into the inner core. That's what I previously thought that most geothermal energy was.
- beerandt 7y agoOnly about half. The rest is likely residual from gravitational and tidal friction/compression and possibly other unknown sources.
