We can immediately stop producing new gas powered vehicles
I really don’t think we can. There are electric vehicles, but not nearly enough being produced to meet all new car demand. And that’s because the car makers don’t think there’s enough demand for EVs. The auto makers produce what they believe there will demand for, and most still seem to think there is still greater demand for ICE vehicles (or hybrids) than fully electric cars.
I think some companies had tried to bring some BEV cargo trucks to market, but I don’t know if very many have actually been produced.
and building new fossil fuel power plants.
We certainly should, but we’re not. 20 new natural gas power plants will come online by the end of next year.
