Our fuel mix

wind turbines and solar panels

Where does our energy come from?

At Bristol Energy we offer the greenest electricity we can, at the best price we can. And we're helping Bristol to tackle social and environmental challenges such as fuel poverty and climate change – so you can go green, and give back.

Overall our fuel mix for the period between April 2019 and March 2020 was 100% green.

The UK average is 37.9%, so we’re pretty proud of this. Despite being just over four years old, we’re already well above the national average. And we’ll stay green as we grow, by continuing to support renewable generators.

Fuel mix comparison graphs showing Bristol Energy's electricity fuel mix is from 100% renewable energy sources. The UK average fuel mix is made up of 3.9% Coal, 39.4% Natural Gas, 16.6% Nuclear, 37.9% Renewables and 2.2% Other fuels.

Want to go even greener?

Switching your energy supplier to one which provides renewable energy is one of the easiest ways to tackle climate change.

With a strong mix of direct power purchase agreements, local renewable generators across wind, solar and hydro, green energy certificates and lower carbon solutions, we are committed to only offering green tariffs which benefit the environment and our communities.

What is our environmental impact?

As we have become greener, our electricity carbon emissions have lowered to 0%. And we are pleased to say these are below the national average for the year 2019 to 2020.

Carbon Dioxide Emissions

Bristol Energy - 0 g/kWh

National Grid Average – 198 g/kWh

Radioactive waste?

As we buy more renewables direct from our generators, we’re able to buy less power from the National Grid, which means the amount of radioactive waste we produce has comes down to 0% too.
