everything happen for some reasons.. i guess..

sometime if a genius invention/creation is leave unchecked, the world is never gonna be big enough for them, e.g tesla earthquake machine can possible destroy the earth , same thing with atomic/nuclear bomb.

money make the world go around (jpmorgan understand this ), thats what they said.
energy is pretty much free, wind, solar , water, its the method how to harvest it, store it that cause money. ( alot of money and invention)
with or without clean energy,fossil fuel will pretty much needed as it is much cheaper to store and relatively stable.
just like you can always go fishing, but you wont mind having a canned fish in your home is it? just in case.

lessons from the story is: money make the world go round , if you have money you the boss. no money? then you have to call someone else as boss.

if tesla did not rip off his AC patent and contracts, the money from it can be fund for countless of his new projects.

the verdict?

don't get emotional when making big decision
