Biofuels

The fed.gov commissioned a study of biofuel made from corn residue (cellulosic ethanol) and the study concluded that the ethanol is worse for the environment than common gasoline.

A $500,000 study paid for by the federal government and released Sunday in the peer-reviewed journal Nature Climate Change concludes that biofuels made with corn residue release 7 percent more greenhouse gases in the early years compared with conventional gasoline.

Of course, Big Ethanol is howling

The biofuel industry and administration officials immediately criticized the research as flawed. They said it was too simplistic in its analysis of carbon loss from soil, which can vary over a single field, and vastly overestimated how much residue farmers actually would remove once the market gets underway.

Of course they're howling.  Big Anything is furious when any study comes out that says what they do is a bad thing.  Big Ethanol, Big Wind, Big Solar, are all emerging technologies, and we're learning a lot about those technologies, but government subsidies are a bad idea.  They cost a lot of money, they're inefficient.  If you subsidize something you get more of it.  If it's a good idea, the market will take care of it, otherwise it should die on the vine.

I prefer non-ethanol gasoline.

**UPDATE** After posting, I found an article that says that the EPA admits that ethanol blends damage engines.   If you want non-ethanol gasoline for your engines, go to pure-gas.org and do a search for your area.
