Energy is a large portion of the cost of aluminum ingots or tanker cars full of ammonia. It is not a large portion of the cost of constructing new housing. I wouldn't start with energy prices if I were trying to figure out how to make housing affordable. I'd try to contrast e.g. Tokyo, where housing is reasonably affordable, against the city of New York, where it is much less affordable. Japan doesn't have cheaper energy than the US.
