This type of impractical idealism is typical of the left. The website is "progressive"--
http://www.commondreams.org/ I recall Dr. Paul Erlich's book from about 1970 titled: "The Population Bomb"
He warned that by now, we'd be swimming in feces-thick rivers, out of oil, smog-covered skies. But worst of all--out of food.
He was wrong. They do this wild extrapolating technique, to scare the bejesus out of regular folks, and to make them get in line with world greenism.
I used to work in energy. Oil & gas production, then engineering & construction. A fact NOT stated in this epistle is that Alberta province alone, has more hydrocarbon reserves than Saudi Arabia.
We may have to "take" that too, from our Canadian buddies up north. Let me predict they will accept $US instead of going to war.
Let me further predict that the US will provide much of the technology for a shift away from oil.
The article is complete idiocy. Even IF there is a depletion of available oil, it would occur gradually and the laws of supply and demand would result in more exploration and discovery. At the same, alternative energy sources (i.e. natural gas), would become more competitive and a switch to the more cost effective fuel would occur. The wonderful thing about capitalism is that it is a self regulating system that compensates for shortages and drives the development of newer more efficient technology. Leftist idiots just don'e get it.
