Over the past couple of weeks I have given some speeches and appeared on radio talk shows and the subject of water has comes up. Several times people have asked, "what about desalination" has been asked.
Capitol Weekly has run a story today that answers the question.
"According to one report in the 1990s by the California Energy Commission, the energy required to make drinkable water from seawater by reverse osmosis is about 2,500 to 12,000 kilowatt-hours per acre foot.
Although figures are far from exact, that translates into $1,300 to about $2,200 per acre-foot a price tag that depends on the cost of energy, which can fluctuate dramatically.
As a comparison, cost of water at the Metropolitan Water District of Southern California was far less some $200 to $300 per acre-foot, depending on the classification of water."
That cost is still the same today--it is a matter of money that stops us from using water from the ocean.
