Where does my energy come from?

Bulb supplies 100% renewable electricity to all its members from solar, wind and hydro. Every unit of electricity we supply can be traced back to a renewable source. There are different ways to buy this renewable electricity. At Bulb, we partner with generators across the UK to directly purchase their electricity. And we buy energy on the wholesale market with renewable energy certificates to match.

We also supply 100% carbon offset gas. We offset the emissions from the gas we supply by supporting carbon reduction projects around the world. And a chunk of our gas mix comes from renewable sources, too.

Why is it special?
The area around Loch Awe in Argyll is beautiful but wet. Perfect for small-scale hydro power. The people behind Beochlich are pretty special too. Thrive Renewables has a mission to make it easy for people to invest in clean, green energy projects, and they in turn invest in local communities. Here they've helped fund the nearby village hall, a great resource for walkers on the stunning West Highland Way.
