There is enough renewable energy in the US to replace all coal and nuclear power while reducing carbon emission

The nuclear power industry, the politicians they pay for, and the current administration are pushing hard for nuclear power, many claiming nuclear is the answer to global warming. Many argue that we don't have enough renewable energy to meet future demand or supply baseload power. This is simply not the case. There is enough wind power in the US alone to supply energy for both gasoline and electrical consumption. Building the number of wind turbines and transmission system would cost roughly $1 trillion, but once installed, would payback the cost of the entire project in 5 1/2 years in savings. Furthermore, "gas" prices would be 60 cents to $1.50 per gallon. What happens if the wind isn't blowing? The wind is always blowing somewhere, and better transmission and integration of energy sources (wind, solar, geothermal, biomass, along with conservation and efficiency) will mean less dependency on centralized, dirty and dangerous, fossil and nuclear plants. In the US alone there is 6 billion Megawatt hours per year of wind energy potential. In 2005 US gasoline consumption was the equivalent of 1.4 billion MWh/year and electrical generation was 4 billion MWh/year. That's just wind.

Solar has even greater potential. It is estimated that concentrated solar arrays stretching over desert land the size of half the Nevada Test Site and Nellis Air Force Base in Nevada can generate all the electricity currently consumed in the US, replacing coal and nuclear. While such an array would not be concentrated in such a size in one place, it demonstrates the energy potential of existing technologies.
