How exactly would you get the power anywhere else?
Lasers.
Seriously though, haven't they been working on some kind of satellite based power transmission or summat like that? Know they've got wireless power transmission over short range, but I don't recall how far they've gotten in getting it longer.
Barring that or really long power cables, you could probably do something involving batteries of various sorts.
The only satellite-based power generation scheme I can remember involved satellites in geosynchronous orbit gathering solar energy and beaming it down to special stations in the form of microwaves. Nothing that I can come up with involves beaming energy up to satellites and then being beamed down somewhere else.
Batteries would still need to be made, they'd have to be fairly massive, and worst of all would have to be transported to and from Greenland. A single shipwreck could cause country-wide blackouts.
