We get energy from sunlight, wind, nuclear plants, and damns… However, most of the energy that we use comes from fossil fuels. There are three major fossil fuels: Coal, oil and natural gas. These are composed of carbon, hydrogen, nitrogen, oxygen and sulfur. Carbon is the major element in fossil fuels. We obtain energy from fossil fuels by burning them.

Scientists hope to increase the energy potential of ethanol, and develop engines and machines able to run mostly on ethanol. This would be a breakthrough in the field of fuels. Ethanol has many advantages: For one thing, ethanol is renewable, and importantly, is an inexhaustible resource. As opposed to fossil fuels, ethanol will never run out. Secondly, Ethanol is relatively safe and non-toxic.
