What are 5 Renewable Resources?: The Complete Guide

So in this article, we will discuss 5 renewable resources if anyone is confused about 5 renewable resources what happens after all? And hopefully after studying the article all your confusion will end. So Study this article carefully.

What are 5 Renewable Resources?

1. Solar Energy

Solar energy is produced by nuclear fusion taking place in the sun. Fusion occurs when the protons of a hydrogen atom violently collide in the core of the sun and fuse together to create a helium atom.

This process, known as a PP (proton-proton) chain reaction, emits enormous amounts of energy. At its core, the sun synthesizes about 620 million tons of hydrogen every second. The PP chain reaction occurs in other stars the size of our sun and continuously supplies them with energy and heat. The temperature of these stars is about 4 million degrees on the Kelvin scale (about 4 million degrees Celsius, 7 million degrees Fahrenheit).

In stars about 1.3 times larger than the sun, the CNO cycle leads to the generation of energy. The CNO cycle also converts hydrogen to helium but relies on carbon, nitrogen, and oxygen (C, N, and O) to do this. Currently, less than 2% of solar energy is generated by the CNO cycle.

Nuclear fusion by the PP chain reaction or the CNO cycle releases huge amounts of energy in the form of waves and particles. Solar energy is continuously flowing from the sun and throughout the solar system. Solar energy warms the Earth, creates wind and weather, and sustains plant and animal life.

2. Wind Energy

Wind energy, or wind energy, refers to the process of using the movement of air to convert it into mechanical energy or electricity. So then, wind energy is classified as a form of solar energy because it is generated by air passing over the Earth’s surface.

The Technique of Using Wind Energy

An explanation of how a wind turbine produces power is provided below.

Automatic orientation

Wind turbines rotate automatically to face the wind. They may then utilize the kinetic energy of the wind to its fullest potential.

The blades turn

When the wind speed reaches 3.5 meters per second (m/s), the blades begin to rotate. It reaches its maximum power when it reaches a speed of 11 m/s.

For example, if the wind is blowing at 25 m/s, the “feather” blades will slow down. Thus, the turbine avoids excessive stresses.

The gearbox

The gearbox converts the slow rotation of the rotating blades into high-speed motion. It spins the shaft fast enough to power the generator.

The gearbox increased the rotational speed per minute from 13 to 1500.

The generator

The alternator is like a giant enlarged version of a bicycle alternator. When we ride a bicycle, the alternator rotates when it hits the rear wheel. As it spins, it generates enough electricity to turn on the bike lights.

The same thing, but on a much larger scale, happens in a wind turbine. The gearbox transmits its power to the generator, where electricity is produced.

3. Hydroelectric Power

The term “hydroelectric power” refers to electricity generated by turbines that use the potential energy of falling or swiftly flowing water to power generators. The most popular renewable energy source in the early 21st century was hydroelectricity, which in 2019 accounted for more than 18% of the world’s total power producing capacity.

In hydroelectric power generation, water is collected or stored at higher elevations and directed down through large pipes or tunnels (pressure pipes) to lower elevations; The difference between these two heights is called the head. At the end of the journey through the pipes, the falling water turns the turbine. The turbines in turn run the generator, converting the mechanical energy of the turbine into electricity.

Transformers are then used to convert AC voltage suitable for generators into higher voltages suitable for long distance transmission. The structure containing the turbines and generators, as well as the intake pressure pipes or tubes, is called the power plant.

4. Geothermal Energy

Geothermal energy is a type of renewable energy extracted from the earth’s core. It comes from heat generated during the planet’s early formation and radioactive decay of the material. This thermal energy is stored in rocks and liquids at the center of the earth.

Geothermal energy – Eruption circuit High temperatures above 4000°C melt some of the rocks at the center of the Earth and form molten rock called magma. These heats also cause the mantle’s plastic behavior and the upward convection of its parts, since it is lighter than the surrounding rock.

Rocks and water in the earth’s crust can reach temperatures around 370°C.

The thermal energy contained in rocks and liquids can be found from shallow depths to several kilometers below the Earth’s surface.

What are the Advantages and Disadvantages?

As a renewable energy source, the main advantage of geothermal energy is the environment. It produces only one-sixth of the carbon dioxide emitted by a clean natural gas power plant.

Geothermal energy is also cheaper than conventional energy, saving up to 80% compared to fossil fuels.

Unlike other renewable energy sources, such as solar and wind energy, are always available.

Although cheap, durable, and environmentally friendly, geothermal energy is not without its downsides. First, production is limited to areas near the boundaries of tectonic plates. Additionally, after years of use, some locations can become frigid.

Although they are cheaper than fossil fuels once plants have been built, drilling and exploring these sites is expensive. This is partly due to the wear and tear of drills and other tools in such harsh environments.

Geothermal power plants can emit hydrogen sulfide, a gas that smells like rotten eggs. Finally, some geothermal fluids contain low levels of hazardous materials that must be disposed of.

5. Biomass (Organic Material)

Biomass, the total weight or number of living organisms of an animal or plant species (specific biomass) or of all species in a biome (biomass), often referred to as a single the area or volume of the habitat. The weight or number of organisms in an area at any given time is the growing crop.

The total amount of organic matter produced by organisms living in a particular area during a specified period, is called primary or secondary yield (first for plants, second for animals) , usually measured in units of energy, such as grams of calories or kilograms per square meter per year. Weight measurements, for example tons of carbon per square kilometer per year or gigatons of carbon per year, are also commonly recorded.

In a different but related sense, the term biomass refers to plant matter and animal waste specifically used as a fuel source.
