Vermont Launches 'Cow Power' System

odyaws writes "Central Vermont Public Service has launched Cow Power, a system by which power users can opt to buy 25, 50, or 100% of their electricity from dairy farms that run generators on methane obtained from cow manure. Cow Power costs only 4 cents/kWh more than market price, so a household like mine would only pay $5-6/month more at 100% usage. The big question now is whether Vermont-based Ben & Jerry's Ice Cream will use power generated from the manure of cows treated with Recombinant Bovine Growth Hormone."

It's also worth mentioning that methane is a greenhouse gas. It's actually worse than Co2 in this regard, though far less common and also less stable.

Since decomposing cow manure is going to emit methane whether we tap it for power or not (as will the cows themselves) it stands to reason that letting the methane go to waste is more of a greenhouse gas contributor than burning it. After all, the Co2 we release from combusting it will be resorbed by the plants the cows themselves eat, whereas the methane will not. And if we don't burn the stuff, it'll just end up in the atmosphere anyways.
