Technically most sources of available energy on or near the planet are the output of fusion in some way, so this tracks.

- tbrownaw 1y agoEverything except geothermal and fission. Unless you count where the fissionable elements came from, in which case you're only left with the portion of geothermal that's from gravity (residual heat from the earth compacting itself into a planet).
- Jensson 1y agoTidal waves comes from earths rotation, so not fusion nor fission.
- markburns 1y agowhat set off the spinning?
- gattr 1y agoEarth's spin comes from the parent molecular cloud which formed the Solar System (including any impacts during the protoplanetary phase.) And that ultimately from density fluctuations after Big Bang, and the way they led to coalescence of galaxies and galaxy clusters.
- gattr 1y agoTo be nitpicky, our uranium and thorium were made via r-process (rapid neutron capture), which is not the kind of fusion occurring in the Sun at present. [1] https://en.wikipedia.org/wiki/R-process https://en.wikipedia.org/wiki/R-process
