We live in “interesting times” as they say, and the world faces severe energy and climate challenges.

Renewable energy sources such as solar, wind, hydro, geothermal, and biomass, offer a clean and sustainable way to meet the world’s energy needs. 

In this article, we will explore the various types of renewable energy, how they work, their advantages, their disadvantages and their role in creating a sustainable future. We’ll also briefly touch on the future of renewable energy and where we see things going.

What is renewable energy?

Renewable energy refers to energy sources that are replenished naturally and can be used over and over again.

These sources of energy are considered renewable because they are not depleted when used, unlike fossil fuels such as coal, oil, and natural gas. Some of the most common forms of renewable energy include solar, wind, hydro, geothermal, and biomass energy.

Renewable energy is considered a clean and sustainable source of energy that can help reduce greenhouse gas emissions, air pollution and dependence on fossil fuels. It also has the potential to provide energy security, economic benefits and job creation.

We think this is a very cool idea!

types of renewable energy

What are the different types of renewable energy?

Solar energy is generated by harnessing the power of the sun, either through the use of solar panels or other solar technologies including solar water heating (solar geysers) and more. 

Wind energy uses the power of wind that blows and turns wind turbines. Moving wind turbines convert the kinetic energy (movement energy) of the wind into electrical energy.

Hydro energy comes from the kinetic energy of moving water, such as in a river, between dams or a tidal turbine in the sea. Hydroelectric power plants use the movement of water to generate electric energy at massive scale.

Geothermal energy comes from the heat deep inside the Earth. This heat comes from the core of the Earth and can be used in many ways to generate electricity or for heating. 

Biomass energy is produced through the burning of organic matter such as plant material and agricultural waste. Biomass can be converted into electricity, heat, or biofuels.

Tidal energy is produced by the movement of the tides, usually through the use of tidal turbines or barrages constructed in the seas and oceans.

Wave energy comes from the movement of ocean waves, usually through the use of wave energy converters which convert the kinetic energy of the waves into electricity.

Ocean thermal energy is generated by harnessing the temperature difference between the surface and deep waters of the ocean.

Why is renewable energy important?

Renewable energy is important for several reasons:

Environmental benefits: Renewable energy sources produce very little or no greenhouse gases (such as carbon dioxide), unlike fossil fuels, which are the main contributors to climate change. By using renewable energy, we can reduce our carbon footprint and help mitigate the effects of climate change.

Energy security: The world is experiencing an energy crisis with the forces of geopolitics throwing the usual energy supply channels into disarray. Renewable energy sources are locally available, which means that we are not dependent on other countries for our energy needs. This can help reduce our vulnerability to energy price spikes and supply disruptions.

Economic benefits: Renewable energy creates jobs and stimulates economic growth. It can also save money on energy bills, as the cost of renewable energy technologies continues to decrease. Renewable energy adoption will naturally have a negative effect on the fossil fuel companies and the people who work for them, but the net effect to society and the economy is positive.

Social benefits: Renewable energy can improve the quality of life in communities, particularly in developing countries where access to electricity is limited. This is particularly true in countries like South Africa and Zimbabwe where there is extremely limited electricity supply due to government mismanagement and corruption causing the national energy producers to fail. Access to clean, cheap, reliable energy helps reduce poverty and improves access to education and healthcare.

Reducing dependence on fossil fuels: Renewable energy sources are not finite like fossil fuels, and can be replenished naturally. By reducing our dependence on fossil fuels, we can help to ensure that these resources will be available for future generations.

As the world’s population and energy needs continue to grow, renewable energy will play an increasingly important role in meeting these needs in a sustainable way. It is important to invest in research and development of renewable energy sources, to advance the technology and make it more affordable, to help us move towards a more sustainable future.

Let’s dig a little deeper into how different types of renewable energy work and the pros and cons of each.

Solar energy

How does solar energy work?

Solar energy works by converting the energy from the sun into electricity or heat. The most common way to do this is through the use of solar panels, also known as photovoltaic (PV) cells.

Solar panels are made up of photovoltaic cells, which are made of semiconductor materials such as silicon. When sunlight hits a solar panel, the energy from the sun is absorbed by the semiconductor material, causing the electrons in the material to become excited and move around. This movement of electrons generates an electrical current.

The electrical current generated by the solar panel is in the form of direct current (DC) electricity, which is not compatible with the alternating current (AC) electricity that is used in most homes and businesses. To use the electricity generated by the solar panel, an inverter is needed to convert the DC electricity into AC electricity.

Once the electricity is in the form of AC, it can be used to power lights and appliances in the home or business or it can be sent to the grid, allowing the homeowner or business owner to sell any excess electricity back to the utility company (if this is applicable in the area).

Solar energy systems can also be used for heating, for example, by using solar thermal panels to heat water for domestic use or for space heating.

It is also important to note that solar energy systems require a certain amount of sunlight to work effectively, so they are more suitable in areas that receive a lot of sunlight. Additionally, the size of the solar panel system will depend on the energy needs of the home or business.

What are the advantages of solar energy?

There are many advantages to using solar energy, including:

Limited scalability: Solar energy systems are not easily scalable, making it difficult to increase the amount of electricity generated by a single system.

Limited by location: Solar energy systems are most effective in areas that receive a lot of sunlight, making them less suitable in areas with limited sunlight.

Environmental concerns: While solar energy is a clean source of energy, the production and disposal of solar panels can have environmental impacts. The materials used to make solar panels can be toxic and the manufacture of solar panels requires energy and creates waste.

Incompatible with the grid: In some cases the generated electricity may not match the demand or the grid infrastructure may not be capable of handling the electricity generated, which can cause technical problems and blackouts.

Solar energy is a promising and growing source of renewable energy, but it’s important to consider the disadvantages as well as the advantages when deciding whether to invest in a solar energy system. In most cases, these disadvantages can be mitigated with a proper design, planning and maintenance of the solar energy system.

How does wind energy work?

Wind energy works by harnessing the kinetic energy of the wind through the use of wind turbines. A wind turbine is a machine that converts the kinetic energy of the wind into mechanical energy, which is then converted into electrical energy.

The main component of a wind turbine is the rotor, which is made up of several blades. When the wind blows, the blades of the rotor rotate, causing the rotor to turn. The rotor is connected to a shaft, which is connected to a generator. As the rotor turns, it causes the shaft to turn, which in turn causes the generator to produce electricity.

The electricity generated by the wind turbine is in the form of direct current (DC) electricity, which is not compatible with the alternating current (AC) electricity that is used in most homes and businesses. To use the electricity generated by the wind turbine, an inverter is needed to convert the DC electricity into AC electricity.

Wind turbines can be used on a small scale, such as in a single home or small business, or on a large scale, such as in a wind farm. Wind farms can consist of many turbines, connected to the grid, to generate large amounts of electricity.

It’s important to note that wind turbines require a certain amount of wind to work effectively, so they are more suitable in areas that have a consistent and strong wind. Additionally, wind turbines can be quite tall, and their size and visibility can be a concern for some people.

Wind energy is a promising and growing source of renewable energy, but it’s important to consider the disadvantages as well as the advantages when deciding whether to invest in a wind energy system.

How does hydro energy work?

Hydro energy, also known as hydropower, is generated by harnessing the kinetic energy of moving water. This energy is converted into electricity through the use of turbines, generators, and other equipment.

There are several ways to generate hydro energy, the most common methods are:

Impoundment: water is held back by a dam and then released through a turbine to generate electricity.

Run-of-river: this method uses the natural flow of a river to turn a turbine and generate electricity.

Tidal: this method uses the kinetic energy of the tides to turn a turbine and generate electricity.

In the case of Impoundment, water is collected in a reservoir or lake behind a dam. When the water is released, it flows through a turbine, which turns a generator to produce electricity. The turbine is connected to a generator that converts the kinetic energy of the moving water into electrical energy.

Run-of-river hydroelectricity uses the natural flow of a river to turn a turbine and generate electricity, without the need of a dam. This method is suitable for rivers with a consistent flow.
