In a world where people paid the true cost of their energy usage, there wouldn't be an absolute deluge of houses built by terrible contractors with terrible insulation on the market, where the biggest, best and cheapest energy saving measures weren't put in when the house was built.

I want summer in my house during the winter. This should be an explicit goal, because you can't get there by just cranking up the heat since it doesn't deal with draughts and the like. If this were a recognized goal, then everyone would be better off in every way.
