We were probably getting close with whale oil though.

More Experts Now Believe Technology Will Continue to Unlock New Sources
Have we beaten "peak oil"?Our coverage of Peak Oil tended toward "Peak oil theories 'increasingly groundless', says BP chief" or even Alinskyite ridicule: "Re-post: Peak Oil Stalwart to Shutter Forum/News Site, Persue Career as Astrologer".
For decades, it has been a doomsday scenario looming large in the popular imagination: The world's oil production tops out and then starts an inexorable decline—sending costs soaring and forcing nations to lay down strict rationing programs and battle for shrinking reserves.
U.S. oil production did peak in the 1970s and sank for decades after, exactly as the theory predicted. But then it did something the theory didn't predict: It started rising again in 2009, and hasn't stopped, thanks to a leap forward in oil-field technology.
To the peak-oil adherents, this is just a respite, and decline is inevitable. But a growing tide of oil-industry experts argue that peak oil looks at the situation in the wrong way. The real constraints we face are technological and economic, they say. We're limited not by the amount of oil in the ground, but by how inventive we are about reaching new sources of fuel and how much we're willing to pay to get at it.
"Technology moves so quickly today that any looming resource constraint will be nothing more than a blip," says petroleum economist Phil Verleger. "We adjust."
Whether peak oil exists is more than just a point of intellectual debate—although it certainly has proved to be a heated and divisive one for decades. The question—and how we think about it—also has a big potential impact for governments, oil producers and ordinary people across the globe, all of whom depend on the vagaries of oil production and would be threatened by soaring costs and shortages.
The peak-oil boosters argue that instead of plowing money into new ways to find oil, we should be conserving what we have and investing in alternative energy sources so that we're prepared when supplies run low and costs soar. Most of the naysayers agree that we shouldn't stick with oil forever. But they think it's wiser to invest in technology to keep expanding the available supply, until it gets too expensive to do so. At that point, they're confident, we'll be able to come up with an economical alternative.
The History of an Idea Peak oil was most widely popularized by M. King Hubbert, a brilliant—and egotistic, by some accounts—geologist who worked for years at Shell Oil. In a 1956 paper, he predicted that U.S. oil production would peak, probably in the early 1970s, and then decline. It would resemble a bell curve....MORE
