People worry about how much land we'd need to supply the US with clean energy. Well,
@elonmusk
and I have independently calculated it and we both come up with something roughly comparable to the area we currently use for maple syrup or golf. A square about 100-120 miles per side.

This map gives you a rough sense of all the ways U.S. land is used. Much of U.S. land serves specific purposes, such as the 2 million acres devoted to golf courses or the 3 million acres for airports.bloom.bg/37XnVYh

Have many calculations like that😊 Norway is very little. But put 1/3 with solar and we produce all the energy the whole world 🌎 use combined. Switching to renewable is not that complicated or expensive💥

Very true. What’s really mindblowing is how much energy the sun outputs & how little of it is absorbed by Earth. There is sooo much solar energy. We can solar power all of human civilization with a tiny % of Earth’s surface, which is a super tiny % of energy emitted by the sun.
