I think this is already happening. OVH built a datacenter in Canada, close to a big dam, so they could get access to cheap electricity and a lot of it. This is just one example, but I would be surprised if that wasn't a consideration in more datacenter placements. The problem of course is to find a place where electricity is abundant, but you also have easy access to the large fiber backbone network. If you have a lot of traffic, fibers aren't cheap, especially interconnecting them with others.
