Renewable Energy, Renewable Resources Types, 10 Examples of Renewable Resources



As a growingly significant topic, energy now touches everyone. The concept of “sustainable development,”, has become an issue that all societies around the world are focusing on today, with emphasis on efficient production and consumption of conventional energy resources while minimizing environmental effects, as well as clean and inexhaustible energy resources (such as sun, wind, biomass, in-ground heat). facilitated the transfer The problems of global warming and environmental pollution that have arisen because of increasing energy demand that is primarily met by fossil fuels, as well as the expectation that fossil fuels will run out in the not-too-distant future, has prompted the widespread use of renewable energy studies. Not being cut off from the rest of the world’s studies in these domains is contingent on both the availability of skilled personnel in these fields and the intensification of research in these topics at universities.


What is Renewable Energy?

Renewable energy is energy derived from the continual flow of energy in natural processes. Fossil fuels account for about 80% of world energy today. Renewable energy sources are critical for reducing our reliance on fossil fuels like coal, oil, and natural gas. Solar, wind, biomass, geothermal, hydraulic, hydrogen, and ocean energy are examples of renewable energy sources (Wave and Tide).

Renewable energy sources are just the resources utilized in the creation of other energy sources such as the sun, water, wind, and wave before they run out. Renewable energy comes from natural sources and is a long-term energy source.

Renewable energy sources, like fossil fuels, do not deplete themselves over time. Nonrenewable energy sources include coal, oil, and natural gas.


Renewable Energy Sources

The following are the basic categories of renewable energy sources. Below is a list of each resource’s specific details.

  • Solar Energy
  • Wind Energy
  • Biomass Energy
  • Geothermal Energy
  • Hydroelectric Energy
  • Hydrogen Energy
  • Wave Energy


Solar Energy

All the planets in the solar system get their energy from the sun. It is a vital resource for all living things, particularly in our environment.

Solar panels are one of the most popular renewable energy sources today, especially during the summer months, due to their ease of use and significant cost savings.

Water may be heated using solar panels, which are commonly seen on the roofs of buildings in towns and villages. The hot water needs of the house can be satisfied, or hot water can be provided to the house’s heating system and utilized to satisfy the heating needs.

Solar energy systems gather the sun’s rays to produce heat or power. Light, heat, and electricity are all forms of solar energy that may be measured.

Solar energy systems transform the energy gathered directly into electricity and may be installed on the rooftops of buildings, appliances, and automobiles. Concentrated solar power plants function on the idea of reflecting solar radiation to a limited area utilizing mirror and lens assemblies and may be used to generate electricity or heat.


Wind Energy

Solar energy is the source of wind energy. The wind is created by the pressure differential that occurs when solar radiation does not heat the land and water at the same pace. Wind turbines built in regions where the wind’s influence is felt the greatest transform the wind’s kinetic energy into mechanical energy, which is subsequently converted into electrical energy. The amount of energy gained from the wind is determined by the present wind speed and the length of time the wind has been blowing.

Today, wind energy supplies 2% of the world’s power. Wind turbine technologies have a low environmental impact when compared to other forms of power generation.


Bioenergy / Biomass Energy

This sort of energy is an infinite resource that can be found almost anywhere. It is regarded as a suitable and vital energy source, particularly in rural regions, because it aids socioeconomic growth.

All organic garbage (fruit and vegetable residues) thrown from houses is a source of biomass, as are specially grown plants such as corn, wheat, grasses, algae, algae in the sea, animal excrement, manure, and industrial wastes, as well as specially grown plants such as corn, wheat, grasses, algae, algae in the sea, animal excrement, manure, and industrial wastes.

Despite the depletion of fossil fuels (coal, etc.) and the pollution they cause, the use of biomass to solve the energy crisis is becoming increasingly significant.


Geothermal Energy

Ground heat is referred to as geothermal. Through fissures in the earth’s crust, the water created because of natural occurrences, particularly precipitation, reaches the magma layer. The magma layer’s heated fluids reach the surface as hot water and steam. Turbines may turn the water and steam that reaches the earth into various forms of energy. Geothermal energy is the thermal energy contained in the earth’s crust in general. The power plants that have been developed turn the energy taken from the ground into electrical energy. They may also be employed in central heating and cooling systems in homes and offices, as well as numerous physical rehabilitation institutions and tourist attractions.


Hydroelectric Energy

The basic principle of hydroelectric energy is to transfer the energy of flowing water into electrical energy. Hydroelectric power stations are a renewable source of energy. They provide nature with a clean energy source. These power plants will be more beneficial in these areas since the flow rate of water will be higher due to the higher altitude. Hydroelectric power plants are used to promote fisheries, facilitate transportation, irrigation, and, most importantly, energy generation since they are dependent on the energy of flowing water.


Hydrogen Energy

Because of the current technology and the difficulties of manufacture, it is not widely employed. However, as technology advances, it is one of the most promising prospects for meeting the world’s energy demands as a clean energy source. In the future, we can discuss the usage of hydrogen energy in the generation of power, heat, and fuel cells.


Wave/Ocean Energy

The oceans can be considered two distinct energy sources. The first is thermal energy, which comes from the sun, and the second is mechanical energy, which comes from waves and tides.

The seas, which cover 70% of the earth’s surface, are also the world’s greatest solar catchers.

Natural thermal energy is created by the temperature differential between the overheated water on the ocean’s top and the colder waters below. If it can be used effectively, even a small portion of this energy will suffice to fulfill the world’s energy demands.
