Elon Musk: Just 100 Miles x 100 Miles Of Solar Panels Would Power US

Wondering how much solar panel would allow the United States to raise all of the energy it needs, without fossil fuels? Elon Musk says only a 100 mile by 100 mile corner of the nation--supported by a 1 mile by 1 mile battery bank--could power all of the power needs for all of the nation. In a speech to the National Governors Association in July, Musk described exactly how the U.S. might move to 100 percent solar power, among other topics.
