We KNOW that most of that power includes fossil fuels. We don't claim otherwise. We also know that the EVs themselves produce zero emissions and any emissions arising from the electricity they use comes from a facility that is far better at cleaning its emissions than any ICE vehicle. We are also generally advocates of moving away from fossil fuels to cleaner forms of energy. So there's absolutely no hypocrisy in the position of promoting EV's. So just stop with this bullshit argument. You're just embarrassing yourself.
Please correct me if I am wrong, but, I have read that if the United States would harvest every photon of light from the Sun that such energy (in Joules) would only meet 50% of that which we consume.
It's wrong. Energy usage of the US is about 93 quadrillion BTUs a year, which amounts to just less than 10^20 Joules per year. The solar constant is 1.361*10^3 Joules per square meter per second. That gives about 4*10^10 Joules per square meter per year. Dividing the two, we see that (capturing *every* photon) would take about 2.5*10^9 square meters, which is a square that is 50 kilometers on a side.
Now, efficiency and hours of daylight increase this, but it is still a long way from the total area of the US.
