What, you weren’t persuaded by my Clunker Lessons for Healthcare post? Ok, how about we look at another one of government’s “great ideas” put into action:
Researchers used to agree that farm-grown fuels would cut emissions because they all made a shockingly basic error. They gave fuel crops credit for soaking up carbon while growing, but it never occurred to them that fuel crops might displace vegetation that soaked up even more carbon. It was as if they assumed that biofuels would only be grown in parking lots. Needless to say, that hasn’t been the case; Indonesia, for example, destroyed so many of its lush forests and peat lands to grow palm oil for the European biodiesel market that it ranks third rather than 21st among the world’s top carbon emitters.
In 2007, researchers finally began accounting for deforestation and other land-use changes created by biofuels. One study found that it would take more than 400 years of biodiesel use to “pay back” the carbon emitted by directly clearing peat for palm oil. Indirect damage can be equally devastating because on a hungry planet, food crops that get diverted to fuel usually end up getting replaced somewhere. For example, ethanol profits are prompting U.S. soybean farmers to switch to corn, so Brazilian soybean farmers are expanding into cattle pastures to pick up the slack and Brazilian ranchers are invading the Amazon rain forest, which is why another study pegged corn ethanol’s payback period at 167 years. It’s simple economics: The mandates increase demand for grain, which boosts prices, which makes it lucrative to ravage the wilderness.
Classic. Of course, what is most amusing to me is the article embraces the idea of global warming as fact, and does propose, as a means of achieving efficiency, the use of alternative energy such as wind farms. Truth of the matter is that we know that wind farms also introduce their own set of problems.
