were some of our not so pleasant energy sources that we use, and now here are a few examples of cleaner renewable energy sources that are not as widely used but should be for the sake of our world.

ETHANOL, (a type of alcohol created by crops) is a very clean source of energy, especially for fueling automobiles. You may be wondering what it comes from? Here are some of the things that ethanol is produced from: Sugar Cane, Corn, Switchgrass, Wheat and Barely. There are other crops and plants that can produce ethanol as well, but I will let you discover those on your own. Brazil is one of the leading countries that produces ethanol for fuel, in fact, the whole country of Brazil uses mostly ethanol to fuel their vehicles. Check it out at.

SOLAR POWER, (light from the sun is used to provide electricity by shinning onto a solar panel), provides a good source of electricity as long as your have light. Solar panels can be quite expensive depending on how many you desire to purchase, and how large they are. Solar panels are usually used in conjunction with re-chargeable batteries. Using batteries alongside solar panels allows you to store your energy for future use, especially during emergencies or when there is no ready available light. There are many uses for solar panels such as providing electricity in a home to power appliances or on a vehicle to power its propulsion system. For more information regarding solar power check out these sites.

W INDPOWER, (the use of a turbine like a windmill, the wind blows hitting the turbine thus moving it in a circular motion creating electricity.) turbines are a good way to harness the power of the wind which provides cities and homes essential electricity. This is a great source for cleaner energy. Check these out for more information.

WATER, (a molecule known as H2O, two hydrogen atoms are combined with one oxygen atom to form a water molecule.) I am going to give an example of two ways water can provide electricity. The first way is by using a hydroelectric dam, for this to work a dam must be built near a moving body of water, preferably a river. Water moves through the turbines
