Ethanol:Profitable Only With Tax-Breaks and Tariffs
Current grain-based ethanol production systems damage soil and water resources in the U.S. and are only profitable in the context of tax breaks and tariffs.
The current focus on ethanol from corn illustrates the risks of exploiting a single source of biomass for biofuel production. A growing percentage of the U.S. corn harvest – 18% in 2006 – is directed towards grain ethanol production. This has not only resulted in record-high corn prices, it has produced strong incentives for continuously-grown corn, higher-than-optimal use of nitrogen fertilizers, the early return of land in conservation programs to production, and the conversion of marginal lands to high-intensity cropping. All of these changes exacerbate well-known environmental problems associated with intensive agriculture.
