All renewable energy is fusion energy with a really round about way of collecting it
All renewable energy is fusion energy with a really round about way of collecting it
Fossil fuel would I guess be chemically stored fusion energy from a long time ago

I could be wrong, but I think geothermal may be the (sole?) exception to that. That heat is from the formation of the planet and radioactive decay (fission). That heat/energy would have coalesced during the accretion process regardless of whether the sun was adding energy. Again, I think. If I'm wrong, please enlighten as this is an interesting topic.
Edit: I was thinking I might be technically wrong since we can't really "renew" geothermal energy, but Wikipedia does have it classified as renewable:
Geothermal power is considered to be a sustainable, renewable source of energy because the heat extraction is small compared with the Earth's heat content.
Radioactive elements were formed in the last moments of a collapsing star, so even those were formed during fusion.
That is true. I guess it depends on how much of the heat is generated via fission processes and how much is just stored from planetary accretion. I don't have any numbers for that at this moment, but I will certainly concede that geothermal is fusion-assisted lol.
Maybe tidal energy would also be an exception? It's from the motion of the moon, which is the result of ancient planetary collisions?
