1 Renewable and Non-Renewable Resources

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 construct Requires land where there are strong winds Produce a small amount of pollution


5 Hydroelectric Energy Moving water has kinetic energy
Water cycle is powered by the sun Spins turbines connected to electric generators in a dam. Disadvantages: Only in areas where there is a large reliable amount of water. Expensive to build Block 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 cells Can be transferred to water or to heat a house Causes little to no pollution Works best in areas with lots of sunlight! DUHHHH Not available all the time!!



11 Biomass Organic matter from plants and animal waste that contains chemical energy. Produces energy when burned Can be used to cook foods, provide warmth or power an engine Examples: trees, crops, animal waste, and peat Inexpensive, but produces a little pollution. Can be used to produce gasoline


13 Geothermal Energy Produced from heat released from the Earth’s interior. Hot springs, geysers Energy is in the form of heat and can generate electricity.



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 fission Most common nuclear fuel is Uranium. Uranium is obtained through mining.

18 Fossil Fuels Nuclear Fuel

19 Petroleum Type of fossil fuel, also called crude oil.
Taken from the ground by drilling Can be refined into gasoline/kerosene Can also be made into plastic, ink and gum

20 Natural Gas Type of fossil fuel, used for heating and cooking
Some cars use for fuel Butane and Propane Used for heating homes, camp stoves or grills Inexpensive

21 Coal Solid used to generate electricity
Used for heat and transportation More than half the US’s electricity comes from coal-burning power plants

22 How to fossil fuels form???
Take out a blank piece of paper Go to page 440 Draw and write a small paragraph explaining how fossil fuels are formed. Turn in by the end of class!
