With only a limited supply of oil and gas available on Earth, it is extremely important to find alternative sources of energy or else with the depletion of these natural resources, humans will be unable to fulfill a number of basic requirements.
Renewable energy can be defined as any form of power that is derived from a source that cannot be depleted. Wind, solar, geothermal and tidal are examples of renewable energy.
There are several benefits of using renewable energy. It has some dominant environmental, economic and societal advantages. Renewable energy sources do not need any fossil fuels to generate power, which makes them environment friendly. Following are the main sources of renewable energy.
1. Wind
Wind energy commonly used to generate clean power, through the use of wind turbines that harness the power of offshore or land-based wind and convert it to electricity.
2. Solar
Solar energy can be utilized with the use of solar panels that allow us to use the enormous power of the sun to heat and lighten up our homes. Being made of photovoltaic cells, solar panels can easily be applied to roofs and even cars, to transfer sunlight to electricity.
3. Geothermal
The Earth’s core is the home to huge amount of heat. With geothermal power, the heat generated by the Earth can be used to by pulling it up to the surface using pumps.
4. Tidal
As the Earth comprised up to 70 percent of water, tidal energy presents a great source of renewable energy. Imagine the amount of power that many waves can produce. Tidal power uses the natural ebb and flow of the waves to generate electricity.
