Pacific Gas & Electric announced last week that it would start buying natural gas made from cow manure in California.

PG&E signed an agreement with Microgy Inc., a subsidiary of Environmental Power Corporation, to deliver up to 8,000 million cubic feet of pipeline quality renewable natural gas daily. Microgy plans to build four plants on large dairies to convert the manure into biomethane. The agreement allows those four plants to be connected into PG&E's extensive gas pipeline network. In addition to producing renewable energy, each of these facilities can produce significant greenhouse gas benefits.
