Desal plants cause localised brine concentration and screw ecology. If you built them at Salinas (salt pans) maybe that would be ok, and we'd get more flamingoes once the brine shrimp population rose. So you need strong solar and large flat expanses. North Africa? There was a serious proposal to sell solar power to Europe from north Africa. Maybe this is the triple play?

I've looked at Desalination in Southern California. One thing they're trying is to mix the saline water with waste water discharge. One assumes that's better. Other thing I found when poking about is the energy expenditure for some of LA's water sources is close to that of desalination.

I think I'm firmly down on the side of I'm against desalination if it just means more water for almonds. For desalination if it means replacing expensive imported water sources and leaving more water for what's left of the states natural environment.

I feel like things are complicated with a inescapable level of fucked.

Carbon tax (or a similar, more general environmental impact tax) would sort thing out in no time.

It wouldn't matter if someone uses water to raise almonds in the middle of the desert, but it should have its env. impact priced in.

Similarly, it's absolutely ridiculous that large states can't plan ahead for ~20-50 years and instead of building efficient power plants we're stuck with windmills and solar and batteries as the "green" option.
