Alternative Energies

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

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

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

Wind Energy Kinetic energy of the wind is turned into electricity

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

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

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

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

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

Energy provided by falling or moving water Hydropower

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

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