IT’S NOT JUST CAPE WIND, but a far more general problem:

Al Gore has been hectoring Americans to pare back their lifestyles to fight global warming. But if Mr. Gore wants us to rethink our priorities in the face of this mother of all environmental threats, surely he has convinced his fellow greens to rethink theirs, right?

Wrong. If their opposition to the Klamath hydroelectric dams in the Pacific Northwest is any indication, the greens, it appears, are just as unwilling to sacrifice their pet causes as a Texas rancher is to sacrifice his pickup truck. If anything, the radicalization of the environmental movement is the bigger obstacle to addressing global warming than the allegedly gluttonous American way of life. . . .

These dams provide cheap, renewable energy to 70,000 homes in Oregon and California. Replacing this energy with natural gas — the cleanest fossil-fuel source — would still pump 473,000 tons of additional carbon dioxide into the atmosphere every year. This is roughly equal to the annual emissions of 102,000 cars.

Given this alternative, one would think that environmentalists would form a human shield around the dams to protect them. Instead, they have been fighting tooth-and-nail to tear them down because the dams stand in the way of migrating salmon. Environmentalists don’t even let many states, including California, count hydro as renewable. . . .

Their opposition to nuclear energy is well known. Wind power? Two years ago the Center for Biological Diversity sued California’s Altamont Pass Wind Farm for obstructing and shredding migrating birds. (“Cuisinarts of the sky” is what many greens call wind farms.) Solar? Worldwatch Institute’s Christopher Flavin has been decidedly lukewarm about solar farms because they involve placing acres of mirrors in pristine desert habitat. The Sierra Club and Wilderness Society once testified before Congress to keep California’s Mojave Desert — one of the prime solar sites in the country — off limits to all development. Geothermal energy? They are unlikely to get enviro blessings, because some of the best sites are located on protected federal lands.

Kind of makes you doubt their sincerity. If global warming is the crisis they say, then all the other stuff is secondary. If all the other stuff isn’t secondary, then do they really believe it’s the crisis they say? It’s just a Laurie David of a different color.
