Each of the 2000 cows on the Blue Spruce Farm in Bridport, Vermont produces enough methane to keep two 100-watt light bulbs burning perpetually.

Blue Spruce Farm's total electricity yield last year was 1.2 million kilowatt-hours.

Vermont had around 600,000 cows last time I counted, or the potential to generate 360 million kw hours of Cow Power electricity annually.

With efficiency-measures, the average home can reduce its electric needs to 3000 kw hours per year. That would mean Cow-Power in Vermont could supply the annual power needs of 120,000 homes, close to half of Vermont's total households.

There are at least five more farms in Vermont that are about to invest in Cow Power systems, bringing another 2000 cows into our local electric supply-chain.

There are new Energy Bills from Vermont and the Federal government that will make grants more available to fund these projects, as well as remove obstacles by improving net metering regulations in favor of local electricity production.
