Analysis put covering the whole US with solar to cost about $5 trillion and the world about $65 trillion dollars. A lot, but it would pay for itself in about 5 years. The only blockade is all the people making all these trillions from the oil and all the power sources that make them all this money.
Who’s “we”, you and the mouse in your pocket? The solar industry is getting that money, one homeowner, building owner, or lot owner at a time. And then, over time, they earn a profit in the generated energy! Sorry you hate making money doing nothing!
