P.J. Huffstutter is a staff writer for The Los Angeles Times covering food and agriculture issues. She recently wrote about how some Central California farmers have been prevented from turning manure into electricity. The practice involves using a digester to turn the manure into methane, which is then used as a fuel source. A problem occurs when the energy produced fuels a generator, which creates nitrous oxide or smog.
