From the Associated Press (via FoxNews.com):
A westward dash to power electricity-hungry cities by cashing in on the desert’s most abundant resource — sunshine — is clashing with efforts to protect the tiny pupfish and desert tortoise and stinginess over the region’s rarest resource: water.
Water is the cooling agent for what traditionally has been the most cost-efficient type of large-scale solar plants…
The solar hopefuls are encountering overtaxed aquifers and a legendary legacy of Western water wars and legal and regulatory scuffles. Some are moving to more costly air-cooled technology — which uses 90 percent less water — for solar plants that will employ miles of sun-reflecting mirrors across the Western deserts. Others see market advantages in solar dish or photovoltaic technologies that don’t require steam engines and cooling water and that are becoming more economically competitive.
The National Park Service is worried about environmental consequences of solar proposals on government lands that are administered by the Bureau of Land Management. It says it supports the solar push but is warning against water drawdowns, especially in southern Nevada. In the Amargosa Valley, the endangered, electric-blue pupfish lives in a hot water, aquifer-fed limestone cavern called Devil’s Hole…
