West Mojave Solar Proposal to be Water Intensive

Looking over the proposal for the Abengoa Solar's Mojave Solar project description indicates that this plant would use water cooling as opposed to the far more eco-friendly dry-cooling technology proposed in a number of other solar plants.  Just how much water are we talking about?  According to Abengoa Solar, approximately 1,077 acre-feet of water per year for each plant site.  There will be two plant sites.  I had to look it up myself, but a single acre-foot of water is equivalent to 325,851 gallons of water.  In total,  Abengoa's project would consume nearly 350 MILLION gallons of water.  I had to check my math twice.

This is yet another sign of the immaturity of the solar siting situation in the Mojave Desert.  Companies are rushing to stake a claim without thinking about the impact of the project.  Abengoa was smart enough to locate their project on mostly abandoned agricultural fields, but they're making the same mistake as Beacon Energy (read "Got Water?" here) and using a cooling process that is not fit for the desert.
