I'm just jumping in here, but while we're in sci-fi land let me point out that this is usually not done from the Earth's surface (pushing 100 GW through the atmosphere is sub-optimal) but instead in near-Earth orbit, or from the Moon's surface, or something.
So, the power output of the Earth is not 100% relevant, it wouldn't be a load on the planetary grid.

To power it, we'd have to take every nuclear power plant on earth (plus another 2-3x more) and put them up in space. Seems likely, no? :P
