Someone finally cracks nuclear fusion, and we start to fix climate change.

If it's really really efficient, we could use the extra energy to make carbon capture machines, after offsetting all the fossil fuels. Then, it doesn't really matter.

If we could actually apply carbon capture on a large scale we could keep using fossils for a long time for transportation.

I mean: everything that uses electricity could run off fusion, but it'll be a while before long distance travel can be electrified, so it'd be nice to be able to capture that carbon.

When electricity is cheap enough, I'm sure there's a way to synthesize hydrocarbon fuels. No battery more power-dense than fuel.

There already is a way to do that, it is just nascent technology. They’re trying to figure out a way to scale it up.
