why God made North American deserts

No one is talking about the Nellis AFB project in Nevada, soon to be the largest PV installation in North America. The primary contractors are SunPower and Xantrex. The power output will exceed the base's needs, so that I suppose the surplus can keep all those lights on in Las Vegas. This is a great project that has both military and civilian benefits, makes excellent use of the Nevada desert, and will hopefully inspire other desert and sunbelt states to better use use their natural and renewable resources. I don't see how this doesn't bode well for both SPWR and XARXF shareholders.
