Well this is some info I found today pasted below. It comes from http://environmenttexas.org/action/clean-energy/transmission?id4=ES
I was interested in the numbers they say would power all of Texas. Just FYI. Quinta Texas is the national leader in wind power and we have the potential to meet the rest of our energy needs with solar power. In fact, if we put solar panels on an area thirty miles by thirty miles in west Texas, we could generate enough electricity to power the entire state at prices competitive with new nuclear plants! But to bring all that clean wind and solar power from west Texas, we need to invest in our transmission grid. Right now, the Public Utilities Commission is deciding how much renewable energy transmission to build. The most ambitious plan they're looking at would create transmission capacity for almost an additional 18,000 megawatts of wind and solar power, which would reduce smog pollution from power plants by 13% and global warming pollution by 16%.
