### You are right but there are few limitations to fully electrifying the
economy. Intercontinental flight and flying to orbit will require fuels but
this is just a small fraction of what we use energy for.

### I doubt it. The benefit of having a lot of cheap space and high
insolation is offset by the cost of transmission to places that matter
economically, and by the cost of being located in a chaotic third world
situation.

And just to be clear, I am still in favor of using fossil fuels for as long
as they are cheap enough, because fossil fuels are good for people and good
for the planet.
