fossil fuel power plant are tops 40% efficient while ice powered cars are around 33%.
If you power you EV off a fossil fuel power plant, then that difference, minus the grid losses, the charging losses and then the inverter and motor losses, is how much co2 emissions you are saving.
Of course that's assuming your driving habits don't change, with that high upfront investment and relatively lower per mile costs compared to using gasoline.
And that's not to mention the one time emission from the production of that EV amortised on its 15 year hoped-for lifetime.
Beside capturing government subsidies and the arbitrage saving from using temporarily cheaper electricity as fuel, I don't see EVs making much sense either from an economic or a saving the planet standpoint.
Without a zero emission energy production as the source, EVs don't make sense beyond hype and cope.
All fossil fuel electrical generation, and that includes natural gas, has to be shutdown. Or else it will not make a lick of difference.
