Probably hybrid internal combustion/ electric in the next few decades and beyond that, pure electric vehicles.


Interestingly the other alternatives like biofuels, natural gas or propane and hydrogen fuel cells are just not catching on and may fall by the wayside in the search to replace fossil fuel combustion engines.

Autonomous driving cars, from whatever energy source, it is believed will make significant reductions in all kinds of emissions as these robots drive more efficiently than humans!
