Renewable energy is continuously produced by various methods and is replenishable. Some of these energy sources are hydropower, geothermal, solar, and wind power.
While using the power of nature has long been used for transportation, lighting, heating, and other purposes, renewable energy is frequently thought of as a relatively new technology. Renewable energy project
by various countries are being taken up for sustainability.
Ships have been propelled across oceans by the wind, and grain mills have also been powered by it. The sun warmed the day and assisted in starting fires that lasted into the evening. However, over the last 500 years, people have become increasingly reliant on dirtier, more affordable energy sources, including coal.
Types of Renewable Energy
- Solar Energy
Sunlight is one of the most readily available energy sources on Earth, ranking it as the top renewable energy source. Of course, location, season, and time of day all impact how much sunlight we receive.
The “photovoltaic effect” uses solar panels to convert sunlight into electricity through a chemical and physical reaction (or PV).
- Wind Energy
Turbines are used in wind farms to capture wind energy and convert it to electricity. The systems that are used to convert wind energy come in a variety of shapes and sizes. Single-wind turbines are used to support pre-existing energy organizations. In contrast, commercial-grade wind-powered generating systems can power a variety of different organizations that are undertaking renewable energy projects. The variations in atmospheric temperature, along with the Earth’s rotation and the planet’s geography, all contribute to the phenomenon that we refer to as “wind.”
- Hydroelectric Energy
Hydropower is among the most commercially successful sources of renewable energy. A large reservoir can generate a controlled flow of water that will drive a turbine, producing electricity by erecting a dam or barrier. The ability to store electricity for use at times of peak demand makes this energy source often more dependable than solar or wind power. Like wind energy, hydro can occasionally be a more economically viable energy source, depending on the type compared to other energy sources.
- Biomass Energy
Fuel from biomass in this process is solid energy produced from plant materials that are transformed into electricity. However, the core of biomass is burning organic materials to create electricity. This process is now much cleaner and more energy-efficient. Biomass generates power at a significantly lower financial and environmental cost by turning domestic, industrial, and agricultural waste into solid, liquid, and gas fuels.
- Geothermal Energy
Geothermal energy uses the heat trapped in the Earth’s core and is produced by the radioactive particles slowly decaying in the planet’s core rock. We can use highly heated water brought to the surface by drilling wells as a hydrothermal fuel source to run turbines and generate electricity. Pumping steam and hot water into the ground can reduce emissions, making this renewable resource greener.
Geographical location has a strong bearing on the availability of geothermal energy, with places like Iceland having a ready supply that is accessible.
Conclusion
Together with other clean energy sources like nuclear power, renewable energy will make up a sizable portion of the world’s energy mix in the future. The push for a more environmentally friendly lot in power generation by promoting renewable energy projects encourages job growth in the solar and wind industries.
