Look up Edison Motors. Diesel is very efficient if operated at its optimal fuel/air mixture at the right rpm, like what happens in a generator. Emissions are already coming out of coal and gas plants. We have a problem today with infrastructure. Trying to skip the transition by going straight to electric only will not work at scale. This is already being proven. And zero emissions is a myth. What we're doing is shifting emissions upstream. Incremental improvements and gradual reductions using the existing infrastructure while the new infrastructure is organically built due to market pressure is the only way forward. Forcing the leap is failing and will continue to fail.
