Cow Power is Now Power - No Sh*t

Last night I attended a full-house World Premiere screening of Cow Power - a new documentary film about the  unique sustainable energy program in Vermont that turns cow manure into renewable energy resulting in saving farms and the environment.  Methane from the manure gets captured in a "digester" to run generators on the farm. Those generators support the farm's power needs plus make plenty of extra electric power that gets sold to Green Mountain Power for distribution to customers.

Less air pollution, less odor from farming, happy cows ... what more could you want? Well, there are even more benefits from using this system.

The liquid nutrients from the cow manure processed through the digester get used on crops to sustain the farm, and because they're liquids they go directly into the soil in a controlled application. Less problems with manure spreading over fields, so far less runoff and odor, more goodness for the land and our waterways, better crop production. Happy ending #2, right? Yes, but wait, there's even more goodness ...

The rest of the waste from this cow manure processing action gets dried out and turned into nice, fluffy bedding for the cows. They have a soft place to lie down, at far lower cost than buying tons of shavings or straw for the barn floors. And there's so much of that final byproduct stuff that the extra goes into making soil enrichment products for gardeners, sold from the farms or through various distributors (I buy Moo Doo, Moo Grow and Foster Brothers manure made with this stuff for my flower and veggie beds). Now that's an efficient use of cow poop.Vermont currently has 12 digesters online with more coming into production this year. They're huge investments for farmers, and for now require large farms to be cost effective. One way Vermonters-citizens and businesses-help to offset that capital outlay and make it more affordable is through a voluntary self-tax on electric power bills.

It's a closed loop system - cows eat hay and grains, and they make milk (good food) and poop (methane, fertilizer and bulky waste - unless it's turned into Cow Power). This hour-long movie is a first for Allison Gillette, director/producer and recent Emerson graduate.

Here's a trailer from the film:
