GWh a year of renewable power. Texas has already had one power "incident" because all the wind stopped. -- Jim Pennino Remove .spam.sux to reply.
From: habshi on 26 May 2010 18:49 Very interesting . check out the photo http://articles.latimes.com/2010/may/25/business/la-fi-solar-plant-20100525 The sprawling solar installations gobbling up California's deserts have a new competitor, one that claims to generate more energy at lower costs while using less open space. Known as concentrator photovoltaics, or CPV, the technology is featured in an installation that will be revealed Tuesday at Victor Valley College. The school's new 1-megawatt plant, on a six-acre dirt plot in Victorville, will provide around 30% of the campus' power.

You are still an idiot. -- Jim Pennino Remove .spam.sux to reply.
