From what I understand there was a two part problem with the entire thing. The first was how houses weren't really designed for anything past a certain point. The houses didn't have the insulation, and design that a house actually needs to be properly fit, but the prices still went up because of demand.
The second is that the last power station was made in '79. Life the Universe and Everything now has a question for the answer of 42. They didn't make any back ups, or new stations, and nothing could keep up with the demand from all of the new residents.

Pull in an ice vortex, and everything is screwed.
