Truly green energy

Welcome to Britain’s greenest energy company. All our electricity is certified green, and also certified vegan. Our gas is a mix of carbon-neutralised natural gas and sustainable green gas.

What makes us different is that we have no shareholders. So, instead of paying dividends we invest your bills in building new forms of green energy. And, you can be absolutely certain that the energy we supply will not be greenwashed.

Joining Ecotricity is one of the biggest things you can do to help fight climate change.

We've been fighting climate change for 25 years

When we launched in 1995, we were Britain’s only green energy company and we founded the global green energy movement.

Since then we’ve grown and grown, building wind and solar farms to power homes and businesses across the country. As we celebrate our 25th anniversary we continue to lead the way with pioneering innovations in green energy.

In 2001 we helped Sainsbury's switch to green energy by building a wind turbine to power its distribution depot in East Kilbride, Scotland.
The first wind turbines we built on the North Sea Coast were situated near Mablethorpe in Lincolnshire. We've added many more to our collection.
It's always a proud moment when a new windmill is erected and we can start supplying renewable energy to nearby homes and businesses.
The wind turbine generators Ecotricity has built at Ford's Dagenham plant power not just the office complex, but also supply the diesel engine production line with green energy.
We have added significantly to our wind park near Mablethorpe, Lincolnshire, where we capture the energy of the wind blowing off the North Sea and use it to power homes and businesses across Britain.
Former US Vice President Al Gore hands Ecotricity founder Dale Vince the Ashden UK Award for Ecotricity's work in generating sustainable energy.
The credit crunch didn't hold us back. In 2008 we moved forward boldly with our construction plans and also introduced our Green Union Jack.
This image gives you an idea of the scale of the wind turbines we build. This one was built to power a B&Q distribution centre using renewable energy.

Climate Clock

The Climate Clock is a version of the Doomsday clock that has been running since 1947 - this tracks the risk of global man-made disaster, through man made technology (like nuclear weapons) - displaying the minutes and seconds left before midnight, when disaster strikes. The climate crisis is a small part of the calculations made.
The climate clock uses a similar approach, but, focuses only on the climate crisis - which is the biggest and most urgent existential threat we face.
"The Climate Clock is a countdown to the biggest man-made disaster we face - but also a measure by which we can track our progress - moving from fossil to renewable energy. It shows we have no time to lose - the clock is ticking…" Dale Vince, OBE.
Ecotricity is a sponsor of the Glasgow Climate Clock that will run every night until COP26.
