Alternative Energy
What are alternative energy sources?
Alternative energy sources are things that you can use over and over again
Why do we need alternative energy?
Renewable energy is generated from natural resources such as sunlight, wind, rain and tides. These sources are considered renewable because they quickly replenish themselves and are usually available in a never-ending supply.
Wind Energy
Pros: Recently wind has been harnessed as a clean, safe source of electricity.
Cons: Concerns have been raised over the noise produced by the rotor blades, visual impacts, and deaths of birds and bats that fly into the rotors.
Geothermal Energy
Solar Energy
Wind energy is a type of energy that uses wind turbines to generate electricity

Geothermal energy is formed from the heat inside the Earth that causes hot springs,geysers and volcanoes.
Cons:The primary impacts of geothermal plant construction and energy production are gaseous emissions, land use, noise and potential ground disturbances.
Pros:Some countries have used it for thousands of years in some as a source of hot water, cooking and heating.
Pros:Solar collectors and modules are designed to capture some of the sun's energy and change into more usable forms such as heat or electricity
Cons:The main concerns with solar energy include land disturbance/land use, visual changes to the landscape, impacts associated with hazardous materials and potential impacts on water and other resources
Solar energy is energy collected from the sun
