EV experience so far

One BIG question with all of this "green" energy is what is going to be needed to decommission things like wind turbines, solar panels, lithium batteries, etc. when they reach the end of their useful life. On top of that, what will the cost of dealing with the environmental challenges that stem from mining Lithium, Cobalt, and other rare earth minerals needed to make these technologies possible? Given the "There Ain't No Such Thing As A Free Lunch" (TANSTAAFL) rule (Robert Heinlein), I expect that will not be insignificant.

 I wonder how the popularity of EV's will effect gasoline prices in the future. I would think if there is less of a demand for gasoline the price for gasoline would come down. I am surprised how quickly EV's are becoming popular for those who can afford them. Someone I know who works in a Nissan engine factory and he said he is surprised, it's a lttle surprising to comprehend. And I thought I have read high voltage power lines may affect ones health who lives near them I don't know if there is any truth to that. But what if they discover a health risk to sitting in a vehicle near a high voltage battery. 

Constant buzzing sounds drive me crazy.
