With oil prices still flirting with $100 a barrel, everyone is talking about the need for "energy independence." Late last year, President Bush signed the Energy Independence and Security Act of 2007; Sen. John McCain declared, "We need energy independence"; and Sen. Barack Obama called for "serious leadership to get us started down the path of energy independence."

This may all be good politics. But the idea that the United States, the world's single largest energy consumer, can be independent of the $5 trillion-per-year energy business — the world's single biggest industry — is ludicrous. The push for energy independence is based on false premises. Here are a few of the most pernicious.

1. Energy independence will reduce or eliminate terrorism.

In a speech last year, former CIA Director James Woolsey told American motorists: "The next time you pull into a gas station to fill your car with gas, bend down a little and take a glance in the side-door mirror. ... What you will see is a contributor to terrorism against the United States." Woolsey is known as a conservative, but plenty of liberals also eagerly adopted the mantra that America's foreign oil purchases are funding terrorism.

But the hype doesn't match reality. Remember, the two largest suppliers of crude to the U.S. market are Canada and Mexico — neither exactly known as a belligerent terrorist haven.

Moreover, terrorism is an ancient tactic that predates the oil era. It does not depend on petrodollars. And even small amounts of money can underwrite spectacular plots; as the 9/11 Commission Report noted, "The 9/11 plotters eventually spent somewhere between $400,000 and $500,000 to plan and conduct their attack." G.I. Wilson, a retired Marine Corps colonel who has fought in Iraq and written extensively on terrorism and asymmetric warfare, calls the conflation of oil and terrorism a "contrivance." Support for terrorism "doesn't come from oil," he says. "It comes from drugs, crime, human trafficking and the weapons trade."

2. A big push for alternative fuels will break our oil addiction.

The new energy bill requires that the country produce 36 billion gallons of biofuels per year by 2022. That sounds like a lot, but the United States uses more than 320 billion gallons of oil per year, of which nearly 200 billion gallons are imported.
