Nonsense. It is arrogant to claim how green you are when you recharge a car that is using electricity that is generated by mostly coal and gas. As I said, I am all for electric as some short trip commuter car. But If I go to New Mexico or any trip of 200 miles or more, I would have to plan around finding stations. And spending 45 minutes to refill, or, you best find a station every 3 hours on the interstate and average about 10 mph less than a 4 cyl car. The bulk of this nation is devoid of such recharging places outside urban areas. I want to see you go from Yuma to I 40 without planning where the rechargers are. And again, until lightweight rechargeable batteries that are reliable and reasonably priced, well...gee, for one third the price of a Telsa I can buy any number of cars that are going to have as small a carbon footprint as a coal powered (or 6.1% hydroelectric carbon free footprint). The same reason I don't own a LNG or CNG auto is because of the lack of filling stations but even there we have a lot more of those than electric charging stations.
The practical engineering problem that has plagued batteries is how long will they last and how much do they weigh. Will batteries come down in weight anytime in my lifetime? Nope not significantly. And the hoopla for years is that technology doubles every 18 months or so in computers. ... or does it? And at what price point? Same with battery technology. Billions have been spent on the perfect lightweight long life battery. And it isn't there yet. Lithium density is increasing, but that isn't translated into a onger life battery without some serious issues. Sila Nano promised to "potentially" improve efficiency by 40% increase over the next 'few years' but their latest battery isn't quite as good as they were predicting...so far. 40%?
"The EV is said to replace cars with the internal combustion engine (ICE) by ca. 2040. Several technological improvements will be needed to make the electric powertrain practical and economical. Even with oil at $100 a barrel, the price of the EV batteries would need to fall by a factor of three and also offer ultra-fast charging. In terms of carbon footprint, the electricity used to power the EVs would need to come from renewable sources. Published reports say that emissions from EVs powered by America’s electricity grids are higher than those from an efficient ICE."

The battery in the luxury Telsa weighs 1200 lb. and goes 265 miles. An 80,000# truck with a range of 400 mile would need to use about half of its load capacity.
