All You Must Know About Renewable Energy In 2021

Renewable energy, also termed as alternative energy, usually derives from the replenishable resources. Replenishable resources are termed as the non-living resources which can be restored on a repeated occasion with the help of natural processes. The replenishable resources can be recharged numerous times and are in-exhaustible in nature.

Different Types Of Renewable Energy

Renewable energy is produced from natural sources and is constantly replenished. There are different types of renewable energy. They are:

  • Solar energy;
  • Wind energy;
  • Hydro energy;
  • Tidal energy;
  • Geothermal energy;
  • Biomass energy;

Solar Energy

Sunlight is the most profuse, freely and easily available energy resource on our planet. Solar energy is derived from solar power, i.e. sunlight. The energy that is produced from the sun is termed as solar energy and it is the transformation of heat. For thousands of years, people have used solar energy in many possible ways, such as heating, cooking and drying. Solar energy is produced by way of artificial photosynthesis, molten salt power plants, solar heating, photovoltaics, solar thermal energy and solar architecture.

Wind Energy

Wind energy explains the process by which wind is used to generate electricity. Wind turbines metamorphose the kinetic energy present in the wind into a mechanical power. It is one of the fastest growing renewable energy technologies.

Hydro Energy

Hydropower became an electricity source in the late 19th century. World’s first hydroelectric power plant started operating in the United States. Hydroelectric power is produced with the help of moving water. Hydro energy is also termed hydro power or hydroelectric power, generating the power from dams or rivers.

Tidal Energy

Tidal energy is another form of hydropower that transfigures the energy procured from the tides into a useful form of energy. The world is covered by the sea approximately about 36 crore square kilometers, which is about 70% of the total area. Due to the gravitational effect of the moon and the sun on the earth, creating a cyclical movement of the seas, the tides are created. Tidal power is currently located in South Korea, the United Kingdom, France, Russia, China and the Netherlands.

Geothermal Energy

Geothermal energy is the type of energy derived from the core of the Earth. When the planet was originally formed, the heat came from the same and also from the radioactive decay of materials. From such heat, the said geothermal energy is produced. The thermal energy is stored in rocks and fluids in the center of the Earth.

Biomass Energy

Biomass energy is the energy which is generated from living organisms or once living organisms. This energy is said to be organic energy, which means it is produced from plants, woods and wastes. Biomass can be converted into energy like methane gas, ethanol, biodiesel.

Conclusion

Renewable resources will never ever run out, at least not for a million years. They are the alternative to non-renewable resources, like fossil fuels. It is the desire that one day renewable resources will take the place of fossil fuels and to take place fully, continuing innovation of new renewable sources is highly recommended.
