What Is Renewable Energy

If you’re wondering, what is renewable energy, then you’re in the right place. Put simply, renewable energy is created from naturally replenished sources such as water, wind and the sun. These sources are very different to non-renewable sources like oil, coal, and natural gas.

What Can Renewable Energy Be Used For?

Electricity generation

One of the most common uses of renewable energy is to create electricity. The great news is that all renewable energy sources can be and are utilised to generate electricity.

The most commonly used source for electricity generation is currently wind, whereas previously, hydroelectric power was the most popular source.


Many commuters are concerned about their carbon footprint. Changing the transport sector to run using just renewable energy resources is essential for a more sustainable planet.

Solar vehicles are electric vehicles that are powered either largely or entirely by direct solar power. Typically, the PV cells that feature inside solar panels transform energy from the sun into electric energy.

The name “solar vehicle” generally implies that solar power is used to power part of or all of the vehicle’s momentum. Solar energy can also be used to supply power for controls or other additional functions.

Solar vehicles aren’t sold as practical everyday transportation options at the moment as they’re typically reserved for demonstration purposes and engineering exercises, usually sponsored by government departments.

Heating and cooling

Energy from the sun can be used to heat buildings, both residential and commercial. It can also be used to heat water and to power devices and appliances.

Furthermore, people can also make use of feed-in tariffs, which means homeowners can get money back by putting energy back into the grid. Renewable energy can also be used for cooling purposes.

The easiest way of doing so involves pumping water from cold reservoirs or cooling it by pumping the water into pipes laid underground.

The Importance of Renewable Energy

One of the biggest human causes of global warming is CO2 being released into the atmosphere, such as greenhouse gas emissions. These emissions produce an insulation layer around planet Earth, causing temperatures to rise and thus making the planet less habitable.

Renewable energy can help to meet the demands for power around the world without adding to global warming, unlike fossil fuels such as coal, oil, and gas.

The Different Types of Renewable Energy Sources

The Challenges Faced By the Renewable Energy Industry

The initial cost of installation

Greenhouse emissions are one of the leading causes of global warming. Although great effort has been taken to increase the integration of renewable energy into society, the initial costs are very high. One of the biggest challenges in developing renewable energy is the high installation expenses.

Insufficient infrastructure

The energy systems on this planet were originally built to work with fossil fuels. This means changing the national grid will be difficult, and the installation of renewable energy sources will be expensive.

But, as knowledge grows on how to build, manufacture, and operate these new renewable systems, the expenses of launching should drop.

Power storage

Traditional plants that are powered by fossil fuels work on a pre-mitigated basis, meaning they supply a predictable and consistent amount of energy. On the other hand, renewable energy is less reliable.

To prepare for this, investment, research and development into power storage systems is starting to increase.

Financial and economic challenges

Challenges will always emerge when implementing new sources of energy. The impacts of expanding the use of energy sources will come with financial and economic challenges including the unsightliness of power plants, high set-up costs, and the disruption of the environment.

Political challenges

Another big challenge of using renewable energy is political concerns. Key concerns include outdated infrastructures, political paralysis, the denial of climate science, and government and financial restrictions.

Lack of understanding and awareness

Lack of awareness and understanding of renewable energy means that people are hesitant to use it. Plants that utilize fossil fuels are typically built in highly-populated areas, making them a valuable source of employment for local people.

This means people are reluctant to move away from these plants because of the current stable work that fossil fuel plants offer.

What Impact Does Renewable Energy Have On Climate Change?

How Can Businesses Use Renewable Energy?

Businesses can use renewables in similar ways to residential properties. This includes using solar panels, wind turbines, and geothermal pumps.

Plus, if your business has an energy production system installed and it creates more energy than it uses, you can typically sell that power back to the grid. This is not only a money saver but a source of income too.

The Future of Renewable Energy

Ultimately, renewable energy looks like it will become a big part of energy mixes in the future. The journey towards a greener, cleaner future for energy generation is creating more job opportunities in renewable energy industries, such as wind and solar.

Final Thoughts

In conclusion, renewable energy is likely to be used more and more in the coming years. It’s no secret that fossil fuels can harm our planet and renewables are valuable tools in reducing global warming.

Supporting the use of renewables, or even utilising them in your business or home, can speed up the journey to a cleaner energy future.


How can renewable energy benefit the environment?

Just a few of the environmental benefits of renewables include:

  • They create energy that doesn’t produce greenhouse gas emissions and reduce certain air pollution types.
  • They diversify energy supplies and reduce the dependence on imported fuels
  • They create jobs and economic development in installation, manufacturing and other sectors

How does renewable energy affect the economy?

Renewable energy brings many benefits to the economy. Firstly, it creates many job opportunities, including positions in engineering, sales, manufacturing, and installation.

It can also increase the value of properties, create stable energy costs, help reduce the impact of climate change, and provide additional income for landowners.

What is the cheapest form of renewable energy?

Generally, solar and wind are considered the cheapest forms of renewable energy. However, onshore wind farms are more affordable than offshore farms.

Solar electricity generation is typically the most widely used and it’s one of the easiest forms of energy to implement in homes and businesses.

Do renewable energy sources produce greenhouse gases?

Although renewable forms of energy don’t produce carbon dioxide on their own, the manufacturing and installation processes can produce small amounts of greenhouse emissions.

However, compared to traditional fossil fuels such as coal, oil, and gas, the carbon dioxide levels released by these processes is extremely low and generally not harmful.
