Greenhouse Affect

The ink is still moist on Capitol Hill's latest energy bill and, as if on cue, a scientific avalanche is demolishing its assumptions. To wit, trendy climate-change policies like ethanol and other biofuels are actually worse for the environment than fossil fuels. Then again, Washington's energy neuroses are more political than practical, so it's easy for the Solons and greens to ignore what would usually be called evidence.( Read more... )If all this doesn't lead to a great awakening among policy makers, we don't know what will. The studies are even more damning because they examine the issue with the theories of the global warmists and conclude that biofuels actually exacerbate the problem they're supposed to solve. On top of that, they're creating new environmental troubles like deforestation and a reduction in biodiversity that may be worse over time than whatever the importance of observed climate change. In either case, or both, they're damaging the planet more than they're helping it.
Ethanol and biofuel proponents always point out that current options are little more than placeholders, temporary fixes until the technology advances and "second-generation" options emerge: "It's just around the corner," we're told. "No, really, this time it's real." That's why the Congressional energy bill put a cap on corn ethanol and, with lavish subsidies and tax credits, essentially legislated the creation of a speculative new biofuel industry from scratch. One hitch is that the technology never seems to turn that corner. Another is that, as the blockbuster Science studies imply, the unintended consequences of such divination matter more than the self-congratulation that "doing something" provides.
Yet special blame also belongs to the environmentalists, who are engaged in a grand bait-and-switch. They stir up a panic about global warming, and Washington responds to the political incentives. Then those policies don't work and the greens immediately begin pushing a new substitute, whose outcomes and costs are equally uncertain. But somehow, that never seems to discredit the entire enterprise and taxpayers keep footing the subsidy bill. Our guess is that these new revelations will also be ignored. They're too embarrassing.
