Cows generating our electricity

A number of companies including Central Vermont Public Service are moving to technology that allows farmers to make a few extra bucks on their bovines. They are employing a technique that harvests methane from cow manure, generates electricity with it, then processes the manure to serve as an organic bedding for the cows (read: less hay). This solves another huge issue (at least here in Vermont) of waste chemicals from fertilizing agricultural fields leeching into the water system and our beautiful lake.
