7 Types of Renewable Energy Sources

Green energy or renewable energy that can be used to power homes, businesses, and whole communities. Recently the renewable energy landscape has changed drastically with more and more people choosing solar power as their main source of electricity.

Renewable energy is an important topic as we increasingly rely on it. It can be difficult to find the answer to “what is renewable energy?” because there are many different definitions of what it means. This article will help you understand what renewable energy is and how it works.

What is Renewable Energy?

Green energy, also known as renewable or clean energy, includes any power source that can be harnessed without harming the environment.

The key to using ecological energy sources is that they do not hurt the environment. They release less greenhouse gases than other types of energy. The goal of renewable energy is to create sustainable sources of electricity without relying on fossil fuels. 

All around the world, countries are looking for ways to reduce their dependency on traditional sources for generating electric power. Some have already increased their reliance on green energy while others still rely primarily on coal or natural gas-fueled plants for electricity production.

Countries who have invested in this type of technology will likely be able to avoid the worst effects of climate change that come with burning fossil fuels like oil, gas and coal.

However, there is still much debate over whether investing in renewable technologies will actually help stop climate change from happening or if it’s just a waste of money.

How Does it Work?

Renewable energy often comes from sources like wind power, solar power, and geothermal energy.

Wind turbines make electricity with wind or water. Solar panels take in the sun’s light and turn it into electrical power. With geothermal energy, the Earth’s heat is used to produce electricity. Biomass converts organic matter into fuel that can be burned, producing a useful heat source or generating electricity when burned in an engine that turns a generator.

Benefits of Renewable Energies

Besides the fact that they put fewer carbon emissions into our environment, these sources can also be more affordable in the long run.

Renewable energy is a growing industry because it’s good for both people and nature.

The future of Renewable energies is bright thanks to developments such as solar panels becoming cheaper over time; new technologies being invented all the time; and governments around the world investing more money into research and development each year.

Different Types of Renewable Energy Sources

There are many different types of renewable energies and this blog will discuss 5 of them in depth.

Solar Power

The first type is solar power. Solar panels use sunlight to produce electricity for homes and businesses around the world.

Solar energy is a benefit because it is endlessly renewable thanks to the sun. Solar energy has a limitless supply. It could make fossil fuels obsolete. When we use solar energy, it helps the public and the environment.


Wind turbines convert wind into usable power through kinetic motion. Biofuel uses plant material to create heat and electrical energy with little negative impact on the environment.


Hydroelectric produces clean electricity by using water flow from rivers or oceans to turn a turbine generator.

Pumped-storage hydropower is when water flows through the dam and powers the turbines to produce electricity. Run-of-river hydropower uses a channel to funnel water through without going over a dam.


This technology requires combining with other sources such as water, coal, natural gas or biomass to provide heat and power. When you separate the hydrogen from another element, it can be used for both electricity and fuel.

Hydrogen can be a clean burning fuel. It doesn’t pollute the environment because it is just water and hydrogen, and that’s what people drink. It can also be used to power electric motors.


Geothermal plants use steam created by natural underground hot springs to generate electricity for homes and offices nearby.


The ocean has two types of energy. One is thermal, and the other is mechanical. Thermal energy relies on warm water surface temperatures to generate energy through many systems. Mechanical energy uses the movement of tides to generate energy created by earth’s rotation and gravity from the moon.

Wave energy is different than other types of renewable energy. Wave energy is more predictable. You can estimate how much you will get with wave energy, but this is not true for other types of renewable energy like sun and wind.
