thanks for the info and a quick google found this :
>pork producers generating electricity
A survey by the
University of Oklahoma Department of Agricultural Economics of owners of anaerobic digesters on swine operations found that the systems produced methane that generated more than $179,000 worth of electricity each year with an initial capital investment of more than $2 million. Government grants covered about 60% of the initial capital investment. Carbon credits also provided some monetary value, which varies depending on the type of credits.<

I'm all for cutting down on fossil fuel use whether it's travel related or energy used./
But feel using this "pork producers generating electricity" and other ways that combine
food being supplied to consumers and using that source for energy purposes is very beneficial for all of us if we want to replace oil and coal as the main energy sources used.
I feel fosil fuel and coal will always have a place when it comes to producing energy, but a far less role and reliance on them for energy produced should be a goal we all should strive for.
Using anaerobic digesters sounds like something that can be helpful in trying to be less reliant on coal and fossil fuel to meet our energy needs
