According to Elon Musk, “One square kilometer is a million square meters. And there's one kilowatt per square meter of solar energy. So on one square kilometer, there is a gigawatt of solar energy… You could power the entire United States with about 150 to 200 square kilometers of solar panels. The entire United States. Take a corner of Utah. There's not much going on there. I've been there.”
What would it take to power the entire USA with solar energy?
