I agree it’s going to be a challenge. But I’m sceptical nuclear is going to help there; from historical experience, it takes upwards of 20 years to build a reactor. Even if that gets expedited through modern technologies, we’re still talking something like 15 years until they come online, and you’re still paying all the upfront costs throughout that time. Whereas solar can go from concept to grid in 2 years, and batteries aren’t much worse.
The desert indeed makes large-scale warm water storage infeasible, but the kind of home setups I mentioned first should still be good to go, it’s basically only your preexisting heating loop times 2 or 3, that’s negligible compared to farming demands, and it stays in the loop forever (except for leakage). Storing warm water that you’d use anyways also doesn’t increase demand.
The desert has the benefit that solar can be really well calculated, since you (mostly) need to consider seasonal changes in sunlight, not cloud cover. That can be planned around
You got a point about the heat pump efficiency though. For new communities there should be a trend towards centralized heating that provides for a whole city block, to make use of economy of scale and raise efficiency beyond what is reasonable for a single home. But that’s dreaming to far, probably
Maybe I wasn’t clear in my comment. I think it’s fine if they quote what somebody tweeted. I don’t think it’s fine to have Twitter embeds in articles.
Come to think of it, I should write a uBlock origin custom rule
