Clean Energy vs Renewable Energy: Understanding the Difference [2023]

As we try to reduce our carbon footprint and tackle climate change, the terms "clean energy" and "renewable energy" are often used interchangeably. But are they really the same thing? Let's find out.

How Are Clean Energy and Renewable Energy Defined?

To start with, clean energy is defined as energy generated from natural, renewable sources that do not pollute the environment. Renewable energy, on the other hand, is defined as energy that comes from sources that are replenished naturally and can be used repeatedly without depletion.

While there is some overlap between the two, not all clean energy is renewable, and not all renewable energy is clean. For example, nuclear power is often classified as clean energy because it has low emissions, but it is not renewable because it relies on uranium which is finite. Similarly, burning biomass is a renewable energy source, but can produce air pollution that makes it not entirely clean.

What Are the Differences and Similarities Between Clean Energy and Renewable Energy?

The main difference between clean and renewable energy is the source of the energy. Renewable energy comes from sources that are replenished naturally, such as solar, wind, hydropower, and geothermal. Clean energy, on the other hand, refers to any source of energy that does not produce greenhouse gas emissions or other harmful pollutants.

However, there is certainly overlap between the two. For example, solar power is both renewable and clean because it uses the sun's energy to create electricity with no emissions. Hydropower is generally renewable, but dams can have significant environmental impacts on waterways and wildlife.

Why Is It Important to Differentiate Between Clean Energy and Renewable Energy?

It is important for us to understand the differences between the two types of energy because they have different environmental impacts. Renewable energy is generally considered to be the best option for reducing our carbon footprint and combating climate change because it does not produce greenhouse gas emissions.

However, not all renewable energy sources are equally clean. For example, a biofuel that is made from crops grown using chemical fertilizers and pesticides may be renewable, but it is not entirely clean.

How Do Clean and Renewable Energy Benefit the Environment?

Clean and renewable energy have many benefits for the environment. Here are just a few:

Clean Energy

• Reduces greenhouse gas emissions and air pollution
• Reduces reliance on fossil fuels
• Helps to protect public health by reducing toxic air pollution

Renewable Energy

• Reduces reliance on fossil fuels
• Reduces greenhouse gas emissions and air pollution
• Supports agricultural and rural economies
• Creates jobs in the renewable energy sector

FAQ

Is clean energy a renewable energy?

Not all forms of clean energy are renewable, but all renewable energy sources could be considered clean.

Why is renewable energy called clean energy?

Renewable energy is called clean energy because it produces no greenhouse gas emissions or other pollutants that can harm the environment.

What is clean energy but not renewable?

Clean energy that is not renewable includes nuclear power and carbon capture technologies, which can reduce emissions from fossil fuel power plants.

Quick Tips and Facts

• Renewable energy sources accounted for nearly 25% of global power generation in 2018.
• China is the world's leading investor in renewable energy.
• Solar energy is the fastest-growing source of renewable energy.

Final Thoughts

In conclusion, while the terms "clean energy" and "renewable energy" are often used interchangeably, they are not the same thing. Clean energy refers to any source of energy that does not produce greenhouse gas emissions or other harmful pollutants, while renewable energy refers to energy that comes from sources that are replenished naturally.

It is important for us to differentiate between the two because they have different environmental impacts and benefits. Renewable energy is generally seen as the more sustainable option, as it does not produce emissions, but some forms of renewable energy are not necessarily clean.

So, as we strive for a healthier planet, let's push for a transition to renewable, clean energy sources. It may take some investment and effort, but the long-term benefits will far outweigh the short-term costs.
