In Indian villages, almost one-third of all the energy used comes

Click on this image to see how dung is used to generate fuel in an Indian village. Dung from livestock is put into a brick tank, and then it flows down to the main tank. Here it is all squished up and the gas (biofuel) accumulates at the top. This gas is now taken to the kitchen through a pipe. One single charge can produce enough gas for five days in the kitchen. The same technique can be applied in school, this time with 15-20 tanks. When enough gas accumulates at the top, it can be burned to generate electricity.
In the US, the most widely used biofuel is ethanol. S.E.E.K. encourages all Americans to use biodiesel made from ethanol. Ethanol is a transparent liquid extracted from corn and similar crops. Added to petroleum, ethanol decreases carbon emissions. E5 for example, is the name of a fuel that is 5% ethanol and 95% petroleum. Depending on the ethanol content, fuels can be E10, E20, E85 or even E100. Most cars will run on E5-E100 fuel without needing new or modified engines (really old cars might go boom!), but we recommend you consult a mechanic before filling your gas tank with ethanol.
One problem with ethanol is that corn for livestock and human food is diverted to energy production. To meet the total fuel needs of the
