The orignal battle was ICE vs steam vs electric. ICE won that war 100 years ago. Why are we refighting it?
There was a point 50 years ago when it appeared that a lack of oil might eventually make the ICE obsolete. That was one reason. Of course, that notion has been blown to hell. I’m going take a guess and say the main reason is the fact that generations of green cronies have been getting filthy rich promoting the battle.
