Tasmania has lots of Hydro (when there is water), SA has lots of wind power and solar, but the rest of the country is embedded with fossil fuel. We can swap Petrol/diesel for electricity supplied by coal/gas but is that a significant improvement for our fossil fuel use in transport?

Electric cars simply shift the pollution elsewhere and are not the answer.
Probably the best hope lies in the development of hydrogen powered cars.

Simply stop having so many children and drop the population back a few decades to 2 or 3 billion
As of 2004 and 2016, 96% of global hydrogen production is from fossil fuels (48% from natural gas, 30% from oil, and 18% from coal); water electrolysis accounts for only 4%.
Back to cars, I can't help wonder about all those new more efficient engines that were designed, some by Australian, but never could get the interest. I can't recall any but I do recall oil companies buying rights and appearing to bury the blue prints deep in the volt. It seems we are still at the same point today. Very slow controlled pace by large companies that always analyse profits with change. Completely disregarding the environment for if, or just when, the sky turns brown, the water gets foggy and stinky, and no one on earth will be worried about a car again if ever.

Why work on charge it and run it flat. Charge as you go surely has been considered.
