Renewable energy, or energy from renewable sources (RES), is energy generated from resources that can be replenished relatively easily and rapidly. Solar, wind, biomass, biogas, waves, ocean tides, and geothermal energy are examples of such tools. 

Fuel from non-renewable and non-renewable sources, such as crude oil, natural gas, hard and brown coal, or peat, is the polar opposite of renewable energy. Although solar and wind energy are practically limitless, and the willow field regenerates itself every few years, natural gas and oil take millions of years to develop, and it is unknown if these processes exist today.

Forms of Renewable Energy 

Wind Energy 

We definitely noted the clusters of tall, white, modern windmills as we drove through the open spaces. The energy produced by air movement is increasingly being used and converted into electricity.

It is not cost-effective to erect such structures all over the place. Since wind is produced by differences in the density of air masses, the proper conditions are required for the process to run smoothly.

It’s also important to remember that air movement can be unpredictable. As a result, wind turbines are unlikely to be installed in a densely populated, enclosed area in order to maximize this element’s performance. This renewable energy source was also valued in the past. Windmills, on the other hand, were much simpler in architecture, but the advantage of nature was obvious.

Solar Energy

Solar energy is not only used to generate electricity in photovoltaic cells, but it is also used to generate heat. Photocells can be used in a variety of areas, including single-family homes, calculators, phone booths, automobiles, aircraft, and even spaceships. Solar collectors are devices that turn sunlight into heat. The most common topic is heating water, which is a heat carrier.

Water Energy 

Water can be used to generate energy in a variety of ways. Flow-through hydroelectric power plants are the most common, but they are not environmentally friendly. 


They rely on the fall of water to generate energy, which drives the turbines that generate electricity. Huge dams are often constructed from this location, altering the environment and displacing people. Energy is often derived on a smaller scale from tides or sea waves.

Biomass Energy 

The term “biomass” refers to all of the matter found in living organisms. Biomass can be burned to produce electricity, which is normally done by turbines. Animal faeces, sewage sludge, organic waste, and vegetable and animal oils are all examples of biomass. Special species of plants, such as willow, corn, Jerusalem artichoke, and others, are cultivated specifically to generate biomass.

Fermentation occurs often during processing, resulting in the production of biogas, a fuel used for a variety of purposes, including heating water and powering CNG (Compressed Natural Gas) engines. Biomass is better for the environment than conventional fossil fuels because the carbon dioxide released during combustion is quickly absorbed by plants, resulting in a zero-emissions balance.

Geothermal Energy

Geothermal energy is based on the energy of the Earth’s interior, specifically the energy of water heated by an igneous intrusion. The water “returns,” but at a very high temperature, to the surface. This energy is used to generate heat or electricity. Geothermal energy accounts for up to 30% of Iceland’s total electricity supply.

Renewable energy cannot be considered completely ecologically safe since poorly designed and used devices for its production can damage the natural environment.
