2 What is a renewable resource? A form of energy that can be replaced almost as quickly as it is used.Mostly comes from the Sun or from Earth itself.
3 Wind Energy Wind driving an electric generator Wind will blow as long as the sun is heating the Earth.Captured by wind turbines. The blades turn an electric generator.Disadvantages:Expensive to constructRequires land where there are strong windsProduce a small amount of pollution
5 Hydroelectric Energy Moving water has kinetic energy Water cycle is powered by the sunSpins turbines connected to electric generators in a dam.Disadvantages:Only in areas where there is a large reliable amount of water.Expensive to buildBlock movement of fish and other wildlife
8 Solar Energy Energy from the sun in the form of radiation Converted into energy by the use of solar cellsCan be transferred to water or to heat a houseCauses little to no pollutionWorks best in areas with lots of sunlight! DUHHHHNot availableall the time!!
11 BiomassOrganic matter from plants and animal waste that contains chemical energy.Produces energy when burnedCan be used to cook foods, provide warmth or power an engineExamples: trees, crops, animal waste, and peatInexpensive, but produces a little pollution.Can be used to produce gasoline
16 Non-renewable Resource A resource that is used up faster than it can be replaced.Most energy used in the U.S. is non-renewable.
17 Fossil Fuel vs Nuclear Fuel Nuclear Energy-Formed from the remains of organisms that lived a long time ago.-Release energy when burned, can be converted into electricity to power engines-Most commonly used resource. -Relatively inexpensive to process.Energy released when the nuclei of atoms are split or combined.Fusion or fissionMost common nuclear fuel is Uranium.Uranium is obtained through mining.
