Interesting perspective. To be fair though, I'm sure you could find another self proclaimed expert who is pushing a book that will give a completely different narrative. Regardless of whether one thinks fossil fuels contribute to a warming climate or not, burning coal to heat water to produce steam to make power is dirty, out dated and inefficient. It's basically the same technology used in an old steam locomotive. Smog, carbon monoxide & sulphur dioxide pumped into the air we breathe in a town near you. I'm a fan of nuclear, as long as it's not built by the ocean next to a fault line or run by the Soviets, but they're not cheap to build.

For aviation there isn't yet a viable alternative to Jet A, but to generate electricity there are multiple options now. Many less expensive than coal and gas.
