Socializing Risk: The New Energy Economics

Cross-posted from Triple Crisis.

Despite talk of a moratorium, the Interior Department’s Minerals and Management Service is still granting waivers from environmental review for oil drilling in the Gulf of Mexico, including wells in very deep water. Until last month, most of us never thought about the risk that one of those huge offshore rigs would explode in flames and then sink, causing oil to gush out uncontrollably and befoul the oceans. The odds seemed low, and still do: Aren’t there lots of drilling rigs in use, year after year? Twenty years ago, your elected representatives thought that you’d be happy to have them adopt a very low cap on industry’s liability for oil spill damages.

Nuclear power was never quite free of fears; it was too clearly a spin-off of nuclear weapons to ignore the risk of a very big bang. Yet as its advocates point out, we have had hundreds of reactor-years of experience, with only a few accidents. (And someday when Nevada’s politicians aren’t looking, maybe we can slip all of our nuclear waste into a cave in the desert.) Again, the risks are so low that you’d be happy to learn about a law limiting industry’s liability for accidents, wouldn’t you?

Environmentalists have long warned that the world could run out of energy and resources, from the “limits to growth” theories of the 1970s to the more recently popular notion of “peak oil.” The response from economists has been that prices for energy and raw materials are still moderate, and declined over the course of the 20th century; if we are running out of something, why doesn’t its price skyrocket?

The problem is that what we’re running out of is low-risk conventional energy supplies. Because our economy conceals and socializes energy risks, prices remain deceptively low for an increasingly risky energy supply.

The market wasn’t supposed to work this way. In the mythology of perfect competition, each individual business bears the entire risks of failure as well as reaping the rewards of success. Most small businesses quickly fail, a point which is glossed over in the cheerleading for competition – but the damage is normally limited to the loss of savings and derailing of careers for the unlucky proprietors.

This model of competition and individual risk-bearing may be a great way to decide which restaurants should stay in business. For offshore oil rigs and nuclear reactors, it’s not so good. The risks are enormous, potentially affecting large numbers of innocent bystanders. The costs of these energy technologies are high enough that large companies are the only candidates for using them. And large companies don’t like to bet the existence of the company on uncertain risks from dangerous technologies. Most large companies don’t fail, ever; they do everything they can to avoid bet-the-company risks.

That’s where Congress has stepped in, to socialize the risks of energy supply. The Oil Pollution Act of 1990, adopted in the wake of the Exxon Valdez accident, imposes a tiny tax on the oil industry, currently 8 cents per barrel, to finance the Oil Spill Liability Trust Fund, which now contains $1.6 billion. In exchange for the tax, the Oil Pollution Act limits industry liability for spills to actual clean-up costs plus $75 million. That amount is a pittance for a giant oil company, and is far below the economic losses to the communities affected by BP’s recent spill in the Gulf of Mexico. While BP has said it will voluntarily pay more, U.S. law does not require it, and BP shareholders might not tolerate it.

No utility would ever invest in any reactor without the Price-Anderson Act, which puts a strict upper limit on industry’s liability for a nuclear accident. The limit is now up to about $10 billion (to be shared by the industry as a whole), higher than for oil spills but still far below the damages that could be caused by an accident at a reactor, especially one close to a major city. The federal government has, in addition, guaranteed that it will find a final resting place for nuclear waste from reactors around the country, although Yucca Mountain, the only site seriously debated in the first few decades of discussion, has apparently been rejected.

That’s why risky energy technologies look cheap: Congress has decided that we, the taxpayers, are the industry’s insurance policy. Unlike insurance companies that know what they’re doing, though, Congress doesn’t bother to calculate the real risks and set premiums on that basis. Instead, they pretend that the worst will never happen; happy days and low prices are here again, and again.

We are in danger of applying the same short-sighted approach to the biggest energy risk of all, namely climate change. Pretending that the worst case couldn’t possibly happen is all-important to those who want to go slow on climate policy; the most likely climate outcomes for this century are unpleasant and expensive, while the worst cases are truly catastrophic – and too large and irreversible for anyone to pay for the damages. But not to worry: Those catastrophes are at least as unlikely as an oil rig capsizing and filling the Gulf of Mexico with petroleum.
