Is Fear About Climate Change Causing a Nuclear Renaissance?

Sitting in the belly of the beast -- Dominion's 2,000-megawatt Millstone nuclear power plant in Waterford, Connecticut -- the company's chief nuclear officer, Dave Christian, seems an unlikely environmentalist. But he says concern about climate change is what got him involved in the peaceful pursuit of the atom in the first place.

"I started studying climate science in the 1970s after reading a book [published in 1974] entitled Technology, Society and Man by Richard C. Dorf," Christian says. "It was a very thoughtful study of the feedback mechanisms that go into global warming."

Dominion is the kind of big power player that has long had an antagonistic relationship with the environmental movement. In addition to Millstone Units 2 and 3 (Unit 1 was shut down in 1998), the $45 billion company operates two nukes in Virginia, owns 7,900 miles of interstate natural gas pipelines, 6,000 miles of electrical transmission lines and 965 billion cubic feet of underground natural gas storage.

The case for Dominion as a friend of the Earth is based on a few simple facts: It generates 45 percent of Connecticut's electricity and 30 percent of Virginia's without taking a huge toll in smokestack-emitted global warming gas.

In fact, there are no smokestacks, because (aside from the occasional release of radioactive material) the only thing nuclear power plants vent is steam. What's more, in contrast to the modest current capacity of wind and solar power, nukes can produce very large amounts of electricity -- enough to counter global warming by taking highly polluting coal-burning plants offline even as electricity demand increases.

Nuclear advocates will be the first to tell you that their U.S. plants avoid the emission of almost 700 metric tons of carbon dioxide annually. Worldwide, it's two billion metric tons. Given this reality, some prominent environmentalists have signaled a cautious détente with the nuclear power industry.

While stopping short of endorsing the Bush Administration's push for hundreds of new nukes in the U.S., they say that nuclear power merits reconsideration. But they're being met by equally powerful arguments from the scientific community that nuclear power has never been and never will be a solution to global warming.

The Big Push

As worldwide emissions soar, people wait for a white knight. Newsweek columnist Robert J. Samuelson wrote recently, "We Americans want it all: endless and secure energy supplies; low prices; no pollution; less global warming; no new power plants (or oil and gas drilling, either) near people or pristine places. This is a wonderful wish list, whose only shortcoming is the minor inconvenience of massive inconsistency."

Growing awareness of this inconsistency makes it difficult to dismiss the technology out of hand.

Nuclear power has already won some powerful allies in the environmental community. Fred Krupp of Environmental Defense says, "We should all keep an open mind about nuclear power." Jared Diamond, best-selling author of Collapse, says, "To deal with our energy problems we need everything available to us, including nuclear power," which should be "done carefully, like they do in France, where there have been no accidents."

To which Stewart Brand, another apostate green who founded The Whole Earth Catalog and Whole Earth Review, adds, "The only technology ready to fill the gap and stop the carbon dioxide loading of the atmosphere is nuclear power." James Lovelock, originator of the Gaia theory about the planet's self-regulating systems, has called for, to quote The Independent, "a massive and immediate expansion of nuclear power." Actor Paul Newman visited New York's Indian Point plant and praised its climate role. In many cases, these environmentalists see nuclear as only a temporary fix.
