1. ENERGY

2. Energy Ability to cause change

3. Two categories of energy Kinetic energy- Potential energy- Energy an object has due to its motion Energy stored in an object because of its position

4. Energy Resources and Conservation Energy resources –  Energy conservation – anything that can be used as a source of energy to do work methods of energy use through insulation, increasing energy frequency, and changes in patterns of use

5. http://www.youtube.com/watch?v=q_fvbO2VXjc http://www.youtube.com/watch?v=q_fvbO2VXjc Alternative Forms of Energy Nuclear-energy stored in atomic nuclei that can be transformed into other forms of energy by complex power plants

6. Geothermal Energy Geothermal-Heat flowing from inside the Earth

7. Solar Energy Solar-Energy from the sun

8. Hydropower/Hydroelectricity Hydroelectricity-Electricity produced by the kinetic power of water

9. Wind Energy Wind-Electricity produced by the kinetic energy of wind

10. Biomass Biomass powerPlant material, vegetation, or agricultural wastes (compost) used as a fuel or energy source

11. Using Fossil Fuels as Sources of Energy Fossil fuels- Formed when heat and pressure gradually turns the remains of organisms and plants into oil, natural gas, and coal takes millions of years to form

12. Types of Energy Resources Nonrenewable Resource Examples An energy resource that is used up much faster than it can be replaced Fossil fuels

13. Types of Energy Resources Renewable Resource Example Energy source that is replenished continually Hydropower/hydro- electricity

14. Types of Energy Resources Inexhaustible Resource Example- Energy source that can’t be used up by humans sun

16. Generating Electrical Energy Generator- -device that transforms kinetic energy into electrical energy-in fossil fuel power plants, coal, oil, or natural gas is burned to boil water

17. Turbine Turbine- set of steam- powered fan blades that spins a generator at a power plant to produce electrical energy
