Brothers Kevin and Daryl Maas of Washington State are producing electricity from cow manure.

We use a proven, commercialized technology called a manure digester to harvest methane gas from manure. We burn the methane to create electricity, while sending the processed manure back to the farmers as an organic fertilizer now free of pathogens and odor.

What a great source of energy – as long as people want to drink milk and eat hamburgers, there will be cows. And poo. Puget Sound Energy will be buying electricity from their company, Farm Power Northwest.
