The 2010 Cow Power
Awards Farmer's Insurance
Coop, Middlebury,
Vermont
As you all are hopefully
aware by now,
Handy Toyota has taken a pledge to fight pollution and take part in
sculpting a better tomorrow for our Earth. Not only do we
carry a full line of fuel efficient, eco-friendly Toyota Prius vehicles,
the leader in the green-vehicle realm, but we opt to pay a slightly
higher premium for a program that the Central Vermont Public Service
(CVPS) power company has dubbed Cow
Power.
But what is
Cow Power? Simply put, Cow Power is electricity derived from
cows, something Vermont has an abundance of. The waste that
was once sitting in lagoons, necessitating expensive disposal by farmers
is now used to make electricity. What's more, this waste was
giving off high levels of methane gas, a gas that is produced when
organic matter decomposes, which in turn is released into the
atmosphere. Even though Vermont ranks in the lowest percentile
of greenhouse gasses, the methane gas released from this waste was a
substantial portion of that small percentage. As stated, not
only were the farmers responsible for the removal of this waste, they
were paying premium price for sawdust to line the cows'
beds.
Enter Central Vermont Power Service
and Dave Dunn who together started a coalition of sorts named Cow
Power. The idea was to take this manure and turn it into
electricity. Methane is a highly flammable gas, and under the
right circumstances, and a lot of studying, Mr. Dunn was inclined to
believe that it could be used as a fuel for our lights, refrigerators,
televisions--as stated, for
electricity.
Through much development, CVPS
developed a process by which
they could do just that. Having learned the ins and outs of
the process, it can be simplified into the following
synopsis:*
Cows make
manure (obviously, right?)
The manure is
put into an anaerobic digester. The
digester can hold up to 21 days worth of waste at around 100
degrees. Bacteria converts the waste to methane, and the gas
is built up until it reaches a high enough pressure to be forced through
a pipe as a biogas and enters a modified natural gas
engine.
The biogas
fuels said engine, spinning a turbine to create electricity.
The electricity that is not used for consumer power is recycled to keep
the waste at 100 degrees, as
above.
The
electricity is fed into power lines for all who pay for the plan to
use. One cow can produce enough energy to run a 100-watt light
bulb for a full day's time.
The waste of
the waste, so to speak, is then used to line
the cow's beds, so virtually all of the previously named waste is used;
not exactly waste anymore, one would think. From here, the
process begins anew.
On May 20, 2010,
the good people at the Farmer's Insurance Cooperative in Middlebury,
Vermont, Cow Power advocates in their own right, were nice enough to
accommodate an awards ceremony dedicated to the farmers who jumped on
board with Cow Power, and Vermont companies that have made use of this
amazing energy. Handy Toyota was one of those companies
honored. We were given an award for the fifth leading
contributor to the Cow Power program, with special mention regarding our
donations to the program for every Toyota Prius we sell.

occasion.
