Five of The Best Renewable Energy Sources Including Geothermal Power
Renewable energy refers to the energy that comes from natural sources that can be replenished, for example, the sun and the wind. This type of energy is usually unlimited and causes less damage to the environment.
Types of Renewable energy
Solar energy involves using the sun’s radiation and converting it into trapped heat. The heat is then used to create a chemical reaction that can generate electricity. Unfortunately, solar energy is not free since it is not always available and the amount of solar energy procured varies according to the time of day and season.
The energy from the wind can be used to rotate large blades in windmills to generate electricity. The blades in the windmills help to spin a generator which creates electricity.
The free-flow of water in a river or stream can be used to generate electricity. Water released from a dam can also be used in the same way.
Geothermal energy refers to the heat energy generated and stored in the Earth. Geothermal power plants make use of steam to generate electricity. Due to heat energy stored in the Earth, the water turns to steam.
The steam comes from the reservoirs of hot water found a few miles below the Earth’s surface and carries geothermal energy. This steam rotates a turbine that starts a generator which then produces electricity.
Calpine, a competitive power company is quite popular in the industry. Thanks to power generation companies like this, i.e., Calpine, the Global Geothermal Power Market is projected to be valued at USD 6.9 Billion by 2025.
Biomass involves converting solid fuel made from plants or animals into electricity. By converting agricultural, industrial and domestic waste into fuel, biomass allows electricity generation at a much lower cost.
