List of Green Energy Suppliers in the UK

Wind farm

As winter approaches and temperatures drop, our thoughts naturally turn to keeping our homes light, cosy and warm.

In the past, most of our energy was generated by burning fossil fuels, resulting in harmful carbon emissions.

However, attitudes and behaviours are beginning to change, and research into green energy has exploded over the past 30 years, with new technologies available that can reduce our use of fossil fuels such as coal, oil and natural gas.

Green energy comes from renewable natural sources including wind, rain, sunlight, tides and geothermal heat, and has a much smaller impact on the environment and climate change than fossil fuels.

Green energy is also no longer the expensive option that it once was, with many energy supplies offering inexpensive ‘green’ tariffs in an attempt to attract new customers, which means cheaper energy bills for environmentally conscious consumers.

One thing to note is that green energy is often more focused on greener electricity using technology such as wind turbines and solar parks.

Green gas is much more difficult to generate from renewable sources right now, although some green energy suppliers do offer green gas, such as bio-methane generated by decaying food, animal and plant waste. Other green energy suppliers ensure any non-green gas is carbon neutral, offsetting any emissions by investing in carbon reduction schemes.

Although there’s no way to separate the electricity that comes out your plug socket as coming from renewable or non-renewable sources, suppliers of renewable electricity usually take part in the ‘Renewable Energy Guarantee of Origin’ scheme certified by energy regulator Ofgem, and are awarded certificates representing each unit of renewable electricity that’s been put into the Grid.

In 2015, the UK Government stated that it planned for at least 30% of the country’s electricity to come from renewable sources by 2020 (source). If you want to make the switch to greener energy in your home right now, there are now plenty of green energy suppliers to choose from.

Here’s a list of green energy suppliers in the UK.

  1. I’m really happy about this post, since I’ve been considering changing my Supplier. This is a great website. Most eco-friendly living websites in English are from the US and being a foreigner in the UK is a little harder to find out local things. Great, great website.
