I don't think you can have cheap green energy unless its nuclear and thats never going to happen because omg the children. I would say more people and business would rather have cheap good stuff than 'environmentally conscious' stuff.
Plenty of ways to have cheap green energy that isn't nuclear. Problem is that it's not just flip a switch, and boom! Cheap solar! Like most everything else, economy of scale comes into play, along with tech advances. It's certainly not an overnight solution.
Problem right now is that the dipshits pushing for it ARE treating it like it's a flip the switch deal. As if mandating all new car sales to be electric next year is going to magically transform us overnight.
The other problem, and the one that I think is REALLY going to come back and bite us in the ass is how the government is going to handle losing the revenue that comes from gas taxes. We've already seen this before - they push up CAFE requirements, then throw a temper tantrum about how they're losing a bunch of money due to not selling as much gas since cars get so much better MPGs now. Solution - jack up the gas taxes to compensate.
Well, what are we going to do when the majority of the fleet isn't using gas at all? Solution - transfer those taxes to electricity. Guess what, now we're ALL going to be paying a fortune to turn on a damn lightbulb, because there's no good way to separate out what electricity went to charging the cars vs everything else (there are ways to do this, but you know damn well they're not going to be implemented for tax purposes).
