I agree with nathan and captain, but just a little add is we will never use DC, as it is terrible over distance. Wireless is actually more likely, its even said nikola Tesla figured it out a long time ago, just never wrote it down.
With that being said, electricity is electricity no matter where it comes from (chemical reaction, static, mechanical generation etc.) So adapters to the current way we use it would be a 100% guarantee.
I wasn't suggesting, at all, that you'd do distance transmission in DC.
But there are plenty of concepts for decentralizing portions of power production (where those sources generally seem to produce DC power), or something where you have a whole-house battery (again a DC source), where within the home DC would work just fine and you'd only have AC up to the battery for instance.
And maybe I didn't learn enough electro-magnetism related physics, but I have a hard time imagining large scale "broadcast" of power transmission that wouldn't have some shared bandwidth with "useful" airwaves and interfere with a lot of stuff we currently take for granted.
(but yeah, the concept of completely losing the ability to power something, when at the end of the day it's all just electricity, is pretty out there)
