The best kind of energy
We supply all our members with 100% renewable electricity and 10% green gas. When you switch to Bulb, we make sure that for every unit of electricity you use, a unit is produced and put on the grid by a renewable source like Llyn Brenig Hydro in North Wales. In addition, 10% of our gas comes from biomethane. That's gas produced from organic matter like sewage and manure - which is then reinjected onto the grid (minus the smell).
We buy our energy from independent renewable generators from across the UK. Wherever possible, we have direct relationships with these generators to purchase their output. To cover any shortfalls, we purchase renewable energy on the wholesale market.
We think it's really important that you know where your energy comes from. From hydroelectricity to anaerobic digestion, our generators are an innovative bunch.
Greening up the grid
By being with Bulb, all our members are helping to protect the planet. Every year, the typical home with Bulb saves 1.3 tonnes of CO2 from entering the atmosphere. That's like planting 655 trees.
And for every switch to Bulb, we donate £2 to Edible Playgrounds by Trees for Cities, a charity transforming areas in inner-city schools into vibrant outdoor spaces that teach children about growing and eating healthy food.
Every unit of renewable electricity or gas that we purchase is accredited. This means we can verify the amount of renewable energy we supply. For electricity, this is run by the regulator Ofgem. Every year, like all suppliers, we report on the amount of electricity we've purchased from what source: coal, gas, nuclear and renewables. For Bulb, it's simple: 100% of our electricity comes from renewable sources. We report to the green gas industry too, who verify that 10% of our gas is from renewable sources.
