Thank you.

People also don’t consider the raw materials costs in making the batteries.

There’s only so much lithium on the planet. And can solar and wind, which also have their problems with producing them and disposal, meet the demand?

If the whole country went electric, would there be enough in the grid to supply that demand? I’m guessing not in light of the AI electric demand issue that’s come up recently.

Lets compare

Gas efficiency conservatively 25%
That’s about the worse, some engines do 35% and even some slow moving diesels are better than 50%

EV efficiency:
Power plant efficiency 35%
Grid loses average 6%
Battery efficiency (best batteries) 80%
Engine efficiency 90%

Total EV efficiency 0.35 *.94 * .8 *.9 = 23.5%

25% > 23.5% !!!
or 35% >> 23.5%
So car with gas engines are on average more efficient than the electrical ones!
These numbers are from same green site, so I think the comparison is actually worse for EV than that!
