From my FB reply to many negative comments by this hypercritic.

*No* EV owner needs to have a solar panel system to charge their EV with green electricity. In California there are no coal power plants and the natural gas plants are being replaced with peak shaving utility scale batteries. At times of the day the renewables may be as much as half of the electric supply. Go to caiso.com and click on the green to see the charts.
In a year or so Tesla will be dropping the price of a new EV to where the cost will be the same or less than an ICE car. The cost per mile for an EV is a fraction of a regular car — 1/5 to 1/10 according to some newsmedia but it depends on the local price of electricity and gasoline.
