　　When the Audet family turns on the lights at Blue Farm, they are using electricity that es from s- manure (粪肥)， to be specific。

　　Cos produce a lot of astes. One can create 30 gallons of astes each day. No imagine the output of over 1,000 s at Blue Farm. That's really a big amount。

　　When farrs clean their barns, they put the astes in a big heap, and spread so of them on their fields for fertilizer(肥料). But no places like Blue Spruce Farm have a ne ay of using astes. They use them to produce electricity。

　　Here's ho it orks: A big machine moves back and forth cleaning the barn floor. "The s aren't bothered," says Marie Audet. "They are animals of habit; they get used to it, and just lift one foot and then another to let it go by."

　　The machine pushes the manure into a big 600-gallon tank like a small simming pool. The tank is called a digester (化粪池) because hat happens there is just like hat happens inside a : Bacteria(细菌) get to ork and ntinue to digest the manure。

　　Methane gas (甲烷、沼气)in the atmosphere is knon as a "greenhouse" gas because it keeps heat just like a greenhouse does, causing our pla to arm up. That's an environntal ncern. But the digester has a good result. Its gas is kept and used to poer electric generators (发电机)。

　　At Blue Farm, the generators make enough electricity to poer 400 hos. The Audet family sells the extra electricity they can't use themselves。
