Salty, am getting sold on solar energy. It costs a lot of money to drill for oil then to ship it. Then the cost of running gas stations must be added. Yes, a percent of electricity is lost in the transmission and gasoline used by your car does not have that waste. But the waste of searching for oil and producing it, refining it, and shipping it wastes a lot of money as well.
Lithium is needed in batteries, here are a couple.I like ALB the best, but not in it yet.
