That article is the most accurate. You could say, in 1850, "Holy smokes guys, we're gonna run outta trees to make our trains go! Look at these latest statistics!!"
The market system always works. It's never failed us. That doesn't mean, for SURE, that we won't suffer horrible deaths in the future because we run out of oil (that doesn't even make sense, just ride your bike), but I would trust the free market to come up with the energy solution.
Think about it: If you had the chance to invent/discover a new type of energy to power machines and automobiles, you would patent it and make billions of dollars! Money is the only motivation people have to get away from oil. And when oil reaches $100, then $200, then $250 a barrel, the market will act.
Innovation is what has allowed humanity to survive for so long. Check out this website, it explains how we would get fuel for our fusion reactors (when we invent them):

Pretty much says that, when we invent fusion, we can get 25 tons from the moon to power the US for 1 year. And theres a 10,000 year supply on the moon.
