Interestingly, Burger King just announced that they're changing the diet of their cattle to reduce emissions by 33% (of their cattle, not worldwide). Apparently lemongrass leaves will accomplish this.

Passive design can be climate specific, but I agree, it needs to be built into new designs. The problem that I'm seeing is that "no one" cares: developers will build houses with gorgeous kitchens/bedrooms/living rooms, but the HVAC stem will be bottom-shelf equipment with flex duct run all over the place (and pinched in a few other places). Because no one sees it, nor thinks to question it. We really need to figure out how to make it desirable and something people demand. Maybe that's raising electrical rates or taxing antiquated system design? Some form of hitting a wallet?

I like what you're thinking about geothermal; it sparked a few thoughts, though: Geothermal is expensive because of labor, not necessarily price gouging. Most installers (in my area) put a 10% mark up on everything: finding competent installers is harder and harder these days, so you're paying more and more. HVAC techs can make six figures if they have the experience and aren't afraid to negotiate. Unless, of course, they ARE price gouging, which happens, especially if they're already busy (which has been the case for the past three years).

The technology is solid, though to be frank, a high efficiency air-to-air heat pump will be comparable to geothermal, depending on the climate zone. If we can figure out a cost-effective way to replace gas-fired heat in northern climates with something more eco friendly (and consumer friendly), progress would be made.
