With global warming a rising concern, some environmentalists are rethinking nuclear power because it emits zero greenhouse gases.

“You can’t just write nuclear off,” says Judi Greenwald, director of innovative solutions with the Pew Center on Global Climate Change, an environmental research and advocacy group. “I think everybody feels you have to at least look again” at nuclear power.

That attitude is markedly different from the revulsion that environmental groups have directed toward nukes for most of the past three decades.
