2. Coal 1701 discovered in Virginia 1750 April 13th - Dr. Thomas Walker was the first recorded person to discover and use coal. It was used to power trains and now it is used for U.S. Air Force flies B-52 bomber and C-17 transport aircraft on jet fuel that is gasified coal.

3. Electricity Benjamin Franklin discovered lighting was electricity in 1752. Electricity was used for lightening rods and now it is used for lighting our homes and anything that plugs in.

4. Ethanol It has been around in the form of Moonshine Whiskey since 15th century Scotland. It was used in alcoholic beverages and now it is used in gasoline.

5. Geothermal Geothermal energy was first discovered at Larderello, Italy, in 1903. It used to be used for cooking and heating and now it is used for heating and generating electricity.

6. Hydropower It was discovered in the 1870s by Lester Pelton. It was used as a turbine to power a sewing machine but now it is used for generating electricity.

7. Municipal Solid Waste Municipal solid waste (MSW) landfills were first issued in 1959 by the American Society of Civil Engineers. MSW was originally was just a landfill that people put their waste but now is used to generate electricity.

8. Natural Gas It was discovered by a goat herder in 1000BC. It at first was used to light streets and is now used for cooking and heating.

9. Nuclear It was discovered in 1905 by Albert Einstein. It was used for electricity first and now it is used for weapons of mass destruction.

10. Oil (petroleum)

11. Photovoltaic

12. Solar Thermal

13. Transportation

14. Wind First account of it being used was in Persia in 500A -900AD They used it for travel and to dry clothes, we use it to generate electricity.

15. Wood

16. Classifications of Energy Souces Limited Oil Coal Natural gas Uranium Unlimited Solar Wind Gravitational Tidal Geothermal Fusion Renewable Wood Biomass Glasification Biomass Fermentation Animal power Human Muscle Power

17. Nonrenewable source

18. Kinetic Energy of a motion of a body.

19. Potential The ability of a structure to do work.

20. Conservation of Energy Energy can neither be created nor destroyed. Examples: water being used to produce electricity, a block sliding down an incline plane, and a ball bouncing.
