Answer 1

Because nuclear fusion (which powers the sun) is the holy grail of energy production.

Also because natural gas producers are desperate to con the world into paying 3X as much to travel the same distance they could have gone in an EV, and they are investing heavily in propaganda and projects that require huge public subsidies to be competitive.
