Not to mention, vehicles running on gas are extremely inefficient with most of the energy being used is lost to waste heat rather than propulsion. That isn't the case with EVs. That IS the case with EVs, except the majority waste heat is produced at the power plant, not in the vehicle. The typical fossil fuel plant is less than 50% efficient, and coal plants are around 35% efficient. Not only that, but there is massive energy loss in the transportation of electricity. Every time a step down or step up transformer is used in the grid, a loss of about 2% is present. There is also line loss. Depending on what statistics you're looking at, the losses are reported as being as high as 15% just during distribution.
You need to look at the bigger picture, instead of narrowly focusing.
And what about the extraction of oil from the ground, to the refinement and then transportation of gasoline before it even hits the gas tank to give vehicles about a 16% efficiency rate? All while not being renewable after it has been burnt off.
An EV is around 76%+ efficient in terms of the energy it uses for propulsion, not to mention the use of regen braking to recover even more energy that would otherwise just be lost.
Power generation is a separate debate to how energy efficient end devices (in this case a vehicle) are and can be in the future. There's many ways to generate power, all with their own different levels of efficiency.
The amount of energy that hits the earth from the sun alone each day is staggering, even if we can capture a fraction of that in addition to hydro, wind, nuclear etc.
But without modern slavery(something i'm HIGHLY against) your batteries your using would be 250k +
"hey honey!, battery ran dry again, have to sell off half the house to pay for new one" "OMG mine died to!" "what?!!
