There are some positives though, some of those solar projects may become somewhat cost effective due to the lack of cloud cover so one does see a silver lining in the absence of rain clouds, eh?
If you care to take a run down to Chile (that would be to the south), take a good look at a place called the Atacama Desert. It lies east of the coastal mountains there which block moisture too. In fact, there are years that go by with no rain whatsoever.
So, power up the desalination plants, perhaps using solar power to do so.
There was a reason it was known as THE GREAT AMERICAN DESERT back in the early 1800s.
