12 Nuclear Energy Advantages More efficient than coal Large supply of fuel Disadvantages Radioactive Waste Nuclear Meltdown http://www.youtube.com/watch?v=c0kE0Bm-f6M

13 Renewable Resources Resources that are naturally replaced in a short time. Examples: sunlight, wind, & trees

14 Solar & Wind Energy Sun gives off energy as heat & light Sun is the ultimate source of energy Wind farms

15 Other Alternatives Hydroelectric Tidal Biomass Geothermal Hydrogen
