No , if you run EVs off a grid fossil fuel generator, that's the difference between 33% and 40% efficient. It's not enough to move the needle. It doesn't even pay for itself in terms of emissions.
The energy source absolutely has to be ZERO emissions as well. If not then it's just climate cope.
What the hell are you talking about? That's not how people charge EVs.
EVs on their own are typically 90%+ efficient. Although some are as low as ~85%.
Even running on a generator, though, they'd still be more efficient than any ICE engine found in a car, aside from a Formula 1 engine.
EVs are far cleaner, even if ran on a fossil fuel energy grid.
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.
EVs are less polluting than ICE cars even if ran on a grid 100% fossil fuel powered.
On a typical mixed energy grid, they pollute less than ICE vehicles after ~2 years.
Stop making up nonsense.
