Harvesting Cow Farts

Did you know it takes two cows to power the average California home on what is called "poo power" or cow farts? And that's every about renewable. How does this work? Methane gas is captured from cow manure. Then, after cleaning it up, the West Coast power company Pacific Gas & Electric will feed it directly into PG&E's natural-gas pipelines.
