1. Alternative Energies

2. Solar Energy Energy received by the earth from the sun. This is in the form of solar radiation which then make solar electricity possible.

3. Solar Energy Advantages Independent of power outages Saves money Environmental safe Low or no maintenance

4. Disadvantages of Solar Energy High start up cost Large area needed to put panels in Location of sun is important No energy is created at night

5. Wind Energy Kinetic energy of the wind is turned into electricity

6. Wind Energy Advantages Environmental friendly Wind turbines take up less space than a power station Wind is free Good for remote locations

7. Wind Energy Disadvantages Wind is unreliable Produce less electricity- need more than one turbine Start up very expensive Noise pollution

8. Geothermal Energy To capture the heat under the surface of the earths crust to produce electricity

9. Advantages of Geothermal Environmental friendly No fossil fuels are consumed Little to no maintenance is required Self sufficient

10. Disadvantages of Geothermal Surface of earth must be easy to drill into Start up cost is high Run out of steam- no water May release harmful gases

11. Energy provided by falling or moving water Hydropower

12. Advantages of Hydropower No pollutants Save on natural resources Predictable source Dam is a water reserve and economic draw

13. Disadvantages of Hydropower Disturbs the habitat High start up cost Emits carbon dioxide Diverts natural waterways
