Speaking of “global warming”, an interesting article caught my eye recently.
It seems that Arizona has mandated that 15% of it’s electricity must come from green energy by 2025. Given that Arizona is mostly a desert with lots of sun, you would think that this would be an ideal spot for vast solar energy farms. Well, not exactly.
Utility-scale solar power works by generating steam that spins turbines. Cooling the system at the end of the process consumes almost twice as much water per megawatt hour as coal-fired power plants that use the same cooling technology…
Thus, there is a small problem. Deserts are notorious for their lack of water. A 2009 study by the Congressional Research Service found that,
…a solar expansion in the southwest…could consume as much as 1% of the state’s finite water resources within a few years.
John Jarvis, now Mr. Obama’s National Park Service director, warned in a memo last year that a green boom in the southwest could “strain limited water resources already under pressure from urbanization, irrigation expansion, commercial interests and mining.”
Eventually, technology will allow us to become less dependent on “foreign oil”, but, trying to jam green energy down our throats before then is nothing short of stupid. Particularly when no one seems to be even remotely interested in the consequences.
