| The issue is that water is cheap and nearly free when you have enough, and nearly impossible to get when you don’t. Desalination plants need to be run regularly or everything plugs up/corrodes. They’re also capital intensive and not cheap to operate (as the process itself is expensive per gallon), so expensive to buy and not use, AND not cheap to buy and use. But 90% of the time, California has more water than it can use (literally!), and the remaining 10% of the time, it still isn’t actually out of water in most places, as the water sources are regional or local, and most local or regional water sources are still fine. So you’d be spending a massive amount of money to hedge for an edge case that generally never happens in a way the hedge would economically solve. Which is why they generally don’t actually get built, or if they do, they get built and then decommissioned. At least around here. Other, drier climates (middle east) are different of course. We’ll get there eventually I’m sure. |
How can this possibly be true? Nevada and Arizona are both about to go dry because California is still taking a majority of the water from Lake Mead.
