Very true. Lithium battery is about 85% efficient in delivering the power that was put into it. Now add the energy lost in to level 2 charger (abt 10%) lost in the distribution system (8%) energy lost in transmission (8%) and you get back about 3/4ths of the electrical energy produced by the generators.
But wait! There’s more! Fossil fuel plants are about 33% efficient at converting fossil fuels (coal natural gas and oil) to electricity. If the grid were just fueled by fossil fuel then magical battery cars would burn fossil fuel at 21% efficiency, but I’m not finished ranting. Since battery cars weight about 20% more than ICE cars this reduces the efficiency to about 18%. Compare to 30-32% efficiency of modern vehicles.
However, on the side of the battery fanboys the electric grid is only powered 64% by fossil fuels with the remainder being nuclear and hydro (actually a real renewable) and the magic rainbows and unicorn farts - otherwise known as solar and wind. This gives battery cars a 27% efficiency. Problem is that solar and wind only produce electricity about 25% of the time at best. Hydro and nuclear are base load plants and run flat out all the time so when the wind doesn’t blow and the sun isn’t high in the sky combustion turbines burning natural gas pick up the load.
So in conclusion not only do EVs take far more resources to build, but they produce more carbon dioxide than modern ICE Cars. Not that there is anything wrong with CO2, but thats part of the false narrative that the Democrats and their accomplices are pushing the force us to use inferior but more easily controlled by government EVs.
