There's another issue that comes up, so let me give you an example. Actually, this comes from my own experience, but I'm sure lots of people have this experience.
I live in an apartment, or used to, and I pay the utilities. I don't own the refrigerator. The landlord owns the refrigerator, and it's a crappy old refrigerator. In these situations in which property rights are not carefully defined, the markets don't work very well, and so there's no incentive for anybody to change the refrigerator and save energy.
Has your group thought about the kinds of regulations we might need—say in this specific example, to have refrigerator standards—because the market has broken down?
