As I said elsewhere, I believe there is much more wind and solar energy each than humanity's power demands. It's not a question of total energy, it's a question of cost. And my intuition says that wind would be cheaper because it is of higher density. And in fact wind is significantly cheaper in the current situation where renewable sector is so small that variability and storage isn't an issue.

Wind technology seems quite a bit closer to the best possible implementation than solar, so I would expect more improvement in solar pricing than wind pricing.
If solar improves enough, the capital increments become people going to home depot to buy a 1 kW panel.

If you are capturing energy in space, and channeling it to the ground somehow, how have you reduced net energy reaching the surface of the earth?

The energy is in a different form which won't necessarily raise the temperature of the earth as much as the sunlight hitting the earth would have. Not to mention the hydrocarbon based energy sources replaced by the clean electricity wouldn't be contributing further damage to the environment.

When that energy which has been beamed down from space is used, it WILL give off heat.
Long term, climate management will be necessary regardless.
I just easily see the entire planet being powered by some terrestrial satellite grid of solar panels in a few centuries. Capture it in space, transport it to surface via a space elevator or something, maximum efficiency. Would probably also slow global warming since significantly less heat by that point would be reaching the surface (given the size of an artificial ring belt of solar panels we would need to run everything by then!)
