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
