Renewable energy comes from sources such as the sun, water, wind and organic matter – all resources that are continually replenished by nature and can be converted into energy while producing fewer pollutants than traditional energy sources. In short, compared with our traditional sources of energy, they are more abundant, cleaner and can be produced locally.
Types of renewable energy:
- Solar energy
- Solar energy utilizes the light from the sun to produce power. Unlike fossil fuels, solar energy is available anywhere on earth. Solar energy is free, immune to rising energy prices, and can be used to provide heat, lighting, mechanical power and electricity.
- Wind energy
- Wind mills have been used for various purposes for hundreds of years, but modern wind turbines have only been used to produce electricity for about three decades. Marked advancements in recent years in wind turbine technology and wind mapping technology have greatly increased our ability to better locate and utilize this valuable renewable resource.
- Biomass energy is a renewable, homegrown energy source that includes trees, farm crops, animal waste, plants, and landfill gas.
- Hydroelectric power plants use dams to utilize natural flowing waterways to turn turbines in order to generate electricity. For the purposes of most green power programs, hydropower projects that are considered ‘low-impact’ minimize negative environmental impacts of the dams.
