HerrBlucher ~:” Duh. Thinking people have known this for a long time. Cradle to grave, electric cars are NOT more environmentally friendly than internal combustion cars.”

Most people’s simplistic thoughts about electric cars; sorta like thinking that all “ milk comes from a milk jug “.
They never think about it logicaly.
My understanding is that current batteries are woefully inefficient as ‘power storage units’.
I recall a statement that it takes 16 -18 times the power in order to load electrical power into a battery ,
and that electric generation has to come from some source (natural gas , coal , hydro, wind, solar ).

No, it’s nowhere near that bad. There are losses in the generating, transmission, and charging stages, but as the article states, even with those the electric cars are still about on par, or slightly better than gasoline powered cars. Most modern gasoline powered cars manage only about 25% thermal efficiency (diesels are quite a bit better). Thermal generating stations (coal, oil, natural gas) can manage close to 50% thermal efficiency in generating electricity, although most of that advantage is subsequently lost in (as mentioned) transmission and charging losses. Plus electricity can be generated from relatively non-polluting and/or renewable resources, such as wind, solar, nuclear, etc (although the latter 2 of those typically have some major issues as grid electricity sources).

The major problem with electric cars, as I see it, is that they just aren’t as practical or flexible as internal-combustion powered cars. Heavy, limited storage space (as the battery packs take up quite a bit a room) and limited range (that’s the big one, and not close to being economically solved, yet). Plus there’s little environmental benefit in them, and they cost more - so what’s the point?
