Why is renewable energy called green energy?

Widespread use of renewable energy has become a worldwide goal to reduce our carbon footprint and protect our planet. But why is renewable energy often referred to as "green energy"?  

What is green energy compared to renewable energy? 

While the terms "green energy" and "renewable energy" are often used in the same context, there are significant differences in their meanings in terms of sustainability, as described by the National Grid. Renewable energy refers to energy sources that are naturally restored, such as solar, wind, and hydro power. As these sources are naturally formed, they can be relied on to continuously provide energy, though the processes used to generate this energy aren’t always clean.  

On the other hand, green energy specifically refers to renewable energy sources that have the least environmental impact. Green energy has the ability to produce power without releasing harmful pollution or greenhouse gases into the atmosphere, making it a cleaner and more sustainable option of the two. 

Types of green/renewable energy sources 

Solar energy: Solar energy uses the power of the Sun to generate electricity. Solar panels, typically installed on rooftops or in large solar farms, convert sunlight into electrical energy and are the most common renewable energy source in the domestic sector within the UK. This process produces no emissions and has minimal environmental impact, making it one of the cleanest energy sources available. 

Wind energy: Wind energy, currently the most common commercial renewable energy source in the UK, is generated by converting the kinetic energy of wind into electricity using wind turbines. These turbines can be found on land or out at sea, where wind speeds are typically higher. Wind energy is a highly efficient and sustainable source of power, with the added benefit of taking up relatively small land areas compared to other energy sources. 

Hydro energy: Hydro energy, or hydropower, uses the energy of flowing water to produce electricity. This is typically achieved through dams built on large rivers, with the movement of water spinning turbines in the dam to generate electricity. Hydropower is a reliable and consistent source of energy, though large-scale hydropower plants can have significant impacts on the local environment if not managed properly. 

Geothermal energy: Geothermal energy uses the heat stored beneath the surface of the Earth's to generate electricity and can directly provide heating. As it’s not weather-dependant, this energy source is incredibly efficient and leaves behind a low environmental footprint. Geothermal plants can operate continuously, providing a stable and reliable energy supply, though they are limited in the area they can be used due to the feasibility of the geological conditions available.  

Biomass energy: Biomass energy is produced from organic materials such as plant and animal waste. These materials are burned or converted into biofuels to generate electricity or heat. While biomass is considered a renewable energy source as it’s more sustainable than using fossil fuels, it’s not seen as green energy due to the emissions produced during energy conversion. 

The transition to green energy is crucial for achieving sustainability and reducing the effects of climate change. By using renewable energy sources like solar, wind, hydro, geothermal, and biomass, we can significantly reduce our reliance on fossil fuels and decrease our carbon emissions.
