Our Fuel Mix

It will come as no surprise that our electricity is 100% green – there’s no coal, nuclear, or any other brown energy source in our fuel mix.

Here’s the data for the last year (April 2014 - March 2015), showing you how we stack up against the national average for energy suppliers.

Fuel Supply Ecotricity National Average
Natural Gas 0.0% 29.7%
Coal 0.0% 26.7%
Nuclear 0.0% 22.2%
Other 0.0% 2.1%
All Brown 0.0% 80.7%
Renewable 100.0% 19.3%
Environmental Impact
COemissions 0.0 g/kWh 368.4 g/kWh
Radioactive waste (high level) 0.00000 g/kWh 0.00155 g/kWh

The greenest energy

Not only is our electricity 100% green, it was also the greenest energy in Britain by a long way according to the latest available figures*. You can read all about how we work this out on our Britain’s Greenest Energy page – it’s a simple calculation that looks at the lifecycle carbon emissions of all suppliers in Britain. As you’ll see, no one else comes close...

We generate around 30% of the green electricity we supply ourselves through our own growing fleet of wind and sun parks – the rest we buy from other green generators.
