You ask a good question that is difficult to answer.
It really depends on what government mandates are over that time.
Physics says petroleum fuels are tough to beat, but governments are mandating the move to electric.
China is moving to electric vehicles (powered by hundreds of new coal power plants) and conserving petroleum for their military.
The Biden administration is pushing hard for evs, but that could go out the window in 2025.
Yes eventually though I figure electric has to stand on its own after and despite government giveaways. It seems like a fairy tale solution to a person like me who is not really up on the science. Now running fossil fuel generation to power electric cars? I guess if there is an efficiency to electric cars that might justify even using fossil fuel power generation? Meaning does electric consume startlingly less watts per mile than combustion engines?
