From Cleantechnica:

A recent study released by Public Citizen, a consumer advocacy organization, and several environmental organizations has concluded that solar technology alone could supply electricity for the whole state.

They cite a number of mind-blowing prospects from a variety of sources, all pointing to Texas as having the number one solar generating potential of the US states.

Concentrating solar power in Texas was found by one study to have a potential capacity of 148,000 megawatts. That is just one solar technology type. (The current total solar power capacity of the US is about 9,000 MW, – wind is 26,000 MW). Their study document also states, “11 Photovoltaic plants covering 30 miles by 30 miles could power the entire state.” The types of technology referenced are photovoltaics, thin film photovoltaics, concentrating solar power, parabolic troughs, parabolic dishes/sterling engines, central receivers, linear fresnel reflectors, and solar water heaters.
