It is true that solar energy has huge potential, like wave motion and dozens of other non-fossil-fuel alternatives. However, as long as the oil companies are making soooo much money selling gasoline & diesel fuel and politicians are making millions from their lobbyists, we will never get out from under their thumbs. The other joke is “clean coal” Hahahah. No such thing. It is just one more BS term created by crooks to get tree huggers on their side. Look at their history. They add ethanol to gasoline, making it less efficient, then they charge more for it. Simply stated, they dilute it, creating more of it and charge more for it. A win, win for them. How many of you would stand for it, if it was your booze they were diluting?
