When you turn on the lights at New Farm,you are using electricity that comes from cows.

Cows produce a lot of waste. One cow can create about 135 liters(升)of waste in a single day. There are about 1,000 cows at New Farm. Imagine how much waste they produce every day!

Some of the cow waste is used as fertilizer (肥料)for the fields. But what about the rest? It used to be a problem. But now New Farm has a new way of using cow waste. They use it to produce electricity.

Here's how it works：A big machine moves around to collect the waste. "Hie cows aren't afraid of the machine，" says Mr. Smith，the owner of New  Farm. "TTiey have got used to it,and just lift one foot and then another to let it go by.” After collecting enough waste，the machine then pours it into a big digester(化糞池）In the digester，bacteria(細菌)get to work and much methane gas(沼氣)is produced. Methane gas is known as a " greenhouse” gas because it keeps heat just like a greenhouse does,causing our earth to warm up. But the digester has a good result. Its gas is kept and used to power electric generators(發(fā)電機)， At New Farm,the generators make enough electricity to provide for 400 homes. Mr. Smith sells the electricity his farm does not need.
