What about the existing housing stock? There's a lot of energy upgrades that pay off well over a couple decades, but not when you move an average of every 7 years and the new homeowners don't know how or care to value your upgrades. I think the government could create regulation to fix the incentives here. Something like allowing enhanced energy efficiency to be paid over time by creating a lien on the house that a new homeowner has to continue to make payments towards.
