The best kind of energy
Bulb is the UK's biggest green energy supplier. We provide all our members with 100% renewable electricity. For every unit you use, we make sure a unit is produced and put on the grid by a renewable source including solar, wind and hydro. Plus, our gas is 100% carbon neutral. We offset the emissions from the gas we supply by supporting carbon reduction projects around the world. We’re also one of the biggest buyers of green gas for homes in the UK. So a chunk of our gas mix comes from renewable sources, too.
We buy our energy from renewable generators 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
And for every new member who joins Bulb we donate £2 to Bulb Foundation which makes grants to charities and social enterprises tackling the climate crisis head on.
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.
Our carbon offsets are all verified by the Gold Standard, the Verified Carbon Standard, or the UNFCCC's Clean Development Mechanism. A chunk of our carbon neutral gas is produced from renewable sources, too. These are verified by the Green Gas Certification Scheme or Green Gas Trading Ltd.
