getting ready for life with less oil..,

NYTimes | As oil continued to pour into the Gulf of Mexico on a recent Saturday, Jennifer Wilkerson spent three hours on the phone talking about life after petroleum.

For Mrs. Wilkerson, 33, a moderate Democrat from Oakton, Va., who designs computer interfaces, the spill reinforced what she had been obsessing over for more than a year — that oil use was outstripping the world’s supply. She worried about what would come after: maybe food shortages, a collapse of the economy, a breakdown of civil order. Her call was part of a telephone course about how to live through it all.

In bleak times, there is a boom in doom.

Americans have long been fascinated by disaster scenarios, from the population explosion to the cold war to global warming. These days the doomers, as Mrs. Wilkerson jokingly calls herself and likeminded others, have a new focus: peak oil. They argue that oil supplies peaked as early as 2008 and will decline rapidly, taking the economy with them.

Located somewhere between the environmental movement and the bunkered survivalists, the peak oil crowd is small but growing, reaching from health food stores to Congress, where a Democrat and a Republican formed a Congressional Peak Oil Caucus.

And they have been resourceful, sharing the concerns of other “collapsitarians,” including global debt and climate change — both caused by overuse of diminishing oil supplies, they maintain.

Many people dispute the peak oil hypothesis, including Daniel Yergin, the Pulitzer Prize-winning author of “The Prize: The Epic Quest for Oil, Money and Power” and chairman of IHS Cambridge Energy Research Associates, a company that advises governments and industry. Mr. Yergin has argued that new technology continues to bring more oil.

Andre Angelantoni is not taking that chance. In his home in San Rafael, Calif., he has stocked food reserves in case an oil squeeze prevents food from reaching market and has converted his investments into gold and silver.

The effects of peak oil, including high energy prices, will not be gentle, said Mr. Angelantoni, a Web designer whose company, Post Peak Living, offers the telephone class and a handful of online courses for life after a collapse.

“Our whole economy depends on greater and greater energy supplies, and that just isn’t possible,” he said. “I wish I could say we’ll quietly accept having many millions of people unemployed, their homes foreclosed. But it’s hard to see the whole country transitioning to a low-energy future without people becoming angry. There’s going to be quite a bit of social turmoil on the way down.”
