Does Your Bacon Generate Electricity?

One of many reasons people become vegetarians is environmental concern; not only are forests cut down to create fields for raising livestock, but the emissions generated by livestock contributes to global warming. This article in the New York Times describes the way one farm in Sterksel, the Netherlands has dealt with the environmental impact of meat and dairy production:

That is why a group of farmers-turned-environmentalists here at a smelly but impeccably clean research farm have a new take on making a silk purse from a sow’s ear: They cook manure from their 3,000 pigs to capture the methane trapped within it, and then use the gas to make electricity for the local power grid.

I like that increasing awareness of environmental repercussions has lead to the development of creative and practical farming methods. I'd say "buy Dutch pork!" but the pollution generated by importing it would probably negate the pollution saved by the producers.
