Pacific Gas & Electric isn’t going to the dogs; it’s going to the cows. And rather than causing a ruining effect the ol’ saying implies, PG&E says it’s going to have a greening one.

The San Francisco-based utility (NYSE:PCG) launched a cow-powered contract today with renewable energy company California Bioenergy for its first greenhouse gas emission (GHG) reductions from a dairy farm. The investment is intended to yield 75,000 metric tons of verifiable GHG emission reductions.
