Right, as Musk said, we're going to need a mixture of nuclear and wind. If my calculations are correct you need about 500.000 windmills to cover electricity demand in the US. But electricity demand is only a small fraction of total energy use.
How much energy do all cars in the US use? How much do tractors working the fields? How much do factories burning their own? How much do ships transporting goods? How much do planes flying around? How much do factories in China making our goods? Or mining operations in Indonesia or Congo mining our materials?
If you look at the full picture of sustainable energy, you'll find that covering electricity use by spending a trillion dollars on a 100x100 mile wind farm is a cool idea and a step in the direction, but it's only a step. There's a whole journey ahead of us, and that's what that book teaches.
