5 types of renewable energy sources and their advantages

The world focused on renewable energy for a few years. To combat some of the effects of global warming, various diverse disciplines such as architects, engineers and technologists have jumped on the bandwagon to make renewable energy sources more accessible and increasingly practical.

In our present day, we have many ways to live more sustainable lives. This article will define renewable energy and explain five different types of renewable energy sources and their respective advantages.

What is renewable energy?

Renewable energy is energy produced using the natural resources of the earth. Resources used must be infinite, which means you cannot exhaust these resources.

The opposite of renewable energy is traditional energy, which relies on fossil fuels. The use of these fossil fuels generally causes more damage to the environment than renewables, and fossil fuels are generally limited.

Let us take an example to explain the concept of infinite vs finite. Suppose you are bet online and you use the money. Money is not unlimited, which means it might run out, but if you use sunlight as a resource, you will be able to capture and use new sunlight every day.

This is the difference between infinite and finite resources. There are many analogies that one could use to explain. When it comes to renewable energy, we can use the resource every day without worrying that it will run out. Where, with traditional energy methods, the risk of running out of resources is every day greater.

5 types of renewable energies and their advantages

In this section, we detail five renewable energy sources, solar, wind, hydroelectric, geothermal and ocean. Each section will contain an explanation of energy source and its current advantages.

Solar energy

Solar energy use the sun as the main source of renewable energy. By placing solar panels on the roofs of homes or businesses, you can convert sunlight into heat, electricity, and hot water.

Solar energy is widely known and one of the biggest advantages of solar energy is the fact that the sunlight is endless. By using relevant technology to harvest this endless supply of sunlight, we can move away from traditional fossil fuels.

Wind energy

Where solar energy uses the sun, wind energy uses wind. To harness wind power, you will need to install wind turbines, driven by the wind flowing over the blades of the “windmill” spinning the turbine which will convert wind power into electrical energy.

The main advantage of harnessing wind power is the fact that it is a clean source of energy. This means that there is no air pollution as a by-product when harnessing wind power.

Hydroelectric power

Hydroelectric power is produced by the use of water. Hydraulic turbines are installed in the dams, and the flow of water through the dam’s turbine will generate electricity. Water turbines can also be used in a water channel or funnel.

The Hoover Dam is one of the best examples of a large-scale hydroelectric project. The advantage of hydroelectric power is its versatility. It can be used in large scale projects or small scale projects, like an underwater turbine in small rivers or streams.

Geothermal energy

Geothermal heat is heat that is trapped in the earth; heat is sometimes released to the earth’s surface. It is usually a volcanic eruption. The heat released in the form of to smoke can be captured and used to generate geothermal energy.

Geothermal energy is not a common source of renewable energy, but it can have a significant impact. Because the systems can be built underground, it will leave a small footprint, reducing the effect of carbon emissions.

Ocean energy

The ocean can produce two types of energy, namely thermal and mechanical. Thermal energy uses the warm water on the surface of the sea to generate energy, while mechanical energy uses the ebb and flow of the movement of tidal waves to generate energy.

The biggest advantage of using ocean energy is that it is a natural resource that can be planned and predicted. By predicting the tides, you can estimate the amount of energy that will be produced in a certain period.

In conclusion

The world is moving towards more sustainable goals. By using renewable energy sources, you can help achieve these goals.
