for home for business Sign in Menu Our green energy The best kind of energy 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. Our generators From hydroelectricity to anaerobic digestion, renewable generators are an innovative bunch. We partner with UK generators to directly purchase their electricity. And we buy electricity on the wholesale market with renewable energy certificates to match. Explore our generator map and meet some of our partners. Get to know our generators Greening up the grid By being with Bulb, all our members are helping to protect the planet. The average member lowers their carbon impact by 3.2 tonnes of CO2 a year. That’s the hard work of around 1,590 trees. 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. Verification 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.
