What’s funny is it’s enough energy that a heat pump water heater + solar ends up being more efficient than a solar water heater. Especially in a warm environment.

Oh no. Water heaters are the most efficient form of solar. Newer solar water heaters might be a bit more efficient than old systems, but we are talking like 80->90%. PVC solar peaks in the 20% range.

The problem is the fucking dinosaurs running our politics and voting for fellow dinosaurs. Our 80 year old president and the congress/senate with an average age around 60 (with those in high positions generally being well above that age) is dooming us all. Their clinging to power with opinions formed a half century ago doom everyone. The fact that the most effective way to get them out is their literal death is why nothing gets done.
