There is no such thing as alternative energy to replace oil than maybe natural gas
This reminds me of the old quote,
"Everything that can be invented has been invented."**--Charles H. Duell, Commissioner, U.S. Office of Patents, 1899.
Just because a heavily armed, balding lawyer from NYC can't come up with a better energy solution to make oil a thing of the past, doesn't mean one of the other 7 billion people on the planet can't do it.
All it takes is for one genius to discover some form of free or near-free energy, release that shit on WIKIleaks, and the whole world will suddenly be on a level playing field. The middle east will turn very poor very fast once the oil under their feet is worthless.
Might happen this year, might happen in 150 years. But at some point, thanks to technology and the fact that necessity is the mother of all inventions, it WILL someday happen.
