  1. Energy Resources

  2. Energy Resources Energy Resource- a natural resource that can be converted into other forms of energy to do work

  3. Non-Renewable Resources • Non- Renewable resources- can not be replaces or are replaced much slower compared to how quickly they are used • Fossil Fuels are the most important non-renewable resources

  4. Fossil Fuels • Fossil fuels- energy resources that formed from the remains of buried plants and animals that lived millions of years ago • Coal • Produces much of the world’s electricity • Petroleum • Used in gas, oil, plastics, asphalt • Natural Gas • Used for heating homes

  5. Fossil Fuels

  6. Nuclear Energy • Fission of uranium or plutonium atoms produces thermal energy which boils water and which makes turbines move and produces electricity. • One uranium pellet= 2200 lbs of coal • Because uranium and plutonium are rare this is a non-renewable resource

  7. Nuclear Power

  8. US Energy Consumption

  9. Renewable Resources Renewable resources- energy resources that are more quickly replaced than they are used

  10. Solar Energy Uses light energy from the sun to produce electrical and heat energy

  11. Hydroelectric Power • Hydroelectric power- uses the potential energy of water to create electricity • Dams are built and cause water to fall, turning potential energy into kinetic. • As the water falls in causes turbines to move and transfers energy

  12. Hydroelectric Power

  13. Wind Energy The kinetic energy of wind causes turbines on windmills to move which cause a generator to transfer electrical energy

  14. Geothermal Energy • Thermal energy created by the heating of rock under the Earth’s surface. • Some plants pump water underground, when the water returns, it comes back as steam that can turn a generator

  15. Geothermal Energy

  16. Biomass • Plants capture and store energy from the sun. • When organic materials are burned they release energy • Certain plants can also be turned into liquid fuel • Corn can be turned into ethanol

  17. Biomass
