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
