(36,413 posts)Seven states, Arizona, California, Colorado, New Mexico, Nevada, Utah, & Wyoming have until 2024 to cut their water usage by the amount that Arizona uses in one year or the Bureau of Reclamation will do it for them.
Holy shit. Things are going to get real much sooner than most people are ready for.

(5,553 posts)Solar is a nice supplemental source of energy, but it can't carry the load by itself.
Part of the issue is the minute to minute and hour to hour variation in output. A lot of work goes into balancing output to demand, and that is for non-renewables where output is fully controlled and predictable.
Powering something as massive and expensive as desalinization plants primarily off solar would be extremely difficult. The output is varied, while the consumption needs completely stable input. Voltage spikes/drops, harmonics, and other power quality issues can be very damaging to equipment. Buffering / balancing on that scale would be near impossible, so solar is limited to being a supplemental source of power with current technology.

(5,553 posts)For the huge energy need of large scale desalination, it will take more than just adding solar. The higher the percentage of power that comes from solar, the harder it is to keep the grid stable and the power to consumers clean.

Large-scale desalination systems require tens of megawatts to run and provide tens of million gallons of desalinated water per day. Small-scale systems vary in size from tens to hundreds of kilowatts and provide hundreds to thousands of gallons of water per day.
Topaz Solar Farm / Desert Sunlight Solar Farm, US 550MW
A solar farm 1/10 the size of Topaz would provide enough power to provide millions gallons of water.

(37,980 posts)At least not in the High Plains region. That natural gas mostly comes from oil production as opposed to the hydraulic fracturing of bedrock. But yeah, huge amounts of water gets used for industrial farming. Also there was that whole deal with the Keystone Pipeline running over the South Dakota portion of the Ogallala.

In 1883 during a irrigation conference said this "Gentleman, you are piling up an heritage of conflict and litigation over water rights, for there is not sufficient water to supply the land". The land described is the Colorado River watershed.
