But I do feel that "The powers that be" are ruining the planet and using up irreplaceable natural resources".

I am all for conservation.
"An electric auto will convert 5-10% of the energy in natural gas into motion. A normal vehicle will convert 20-30% of the energy in gasoline into motion. That's 3 or 4 times more energy recovered with an internal combustion vehicle than an electric vehicle".
