Source?? Manufacturing any car is energy intensive, and then they go spewing exhaust for a decade or so.
Fear mongering wont stop the world from changing.
Neither will kissing your own arse, to be blunt, or patting yourself on the back, to be polite.

It ain't fear mongering to point out it takes a lot of work to turn rocks into a high performance battery, from mining and refinement through fabrication and assembly.
In regions where Li batteries are made this work is done by utilities using coal, natural gas, and uranium.
If someone builds a Li battery factory run off solar and wind or hydropower alone, that would be an incredible thing, but the lead time and financing mean that transition to renewable (and someday, lower cost) energy sources for grid electricity will probably have to be led by the utilities and not by individual manufacturers. Progress on this is happening, with new solar and wind projects appearing regularly. It's gonna take a while though. Until then it's a reality that every kWh used driving a battery vehicle must be replaced by another generated with existing grid technology, which is obviously still mainly combustion driven.
Of course, you could charge your tesla only in daylight hours with solar.
Or wind. But then you might need a ride to the kite spot with someone else, 'cause when it's blowing your car is charging.
