About
100Green were the first energy supplier to provide only 100% green gas to domestic and business customers. To this day they are still the only supplier who provide 100% green gas to domestic customers.
They were the first and only private company in the UK to give free shares to its customers.[3] Whilst this scheme has now ended, some customers remain shareholders, and can make suggestions at any time to improve the business and help it grow, and they can attend its AGM and put questions to the board.
100Green's customer base has grown through customer recommendation, sponsorship and social-marketing activities.
Fuel mix
100Green was the first UK energy supplier to offer a choice of green-only tariffs including 100% green gas. All their tariffs are made up of 100% green sources – solar, wind, hydro and biomass and biomethane (green gas).
The EKO Energy Tariff offered by 100Green is independently certified by EKOenergy a global, nonprofit ecolabel for renewable energy. The ecolabel proves that the consumed energy fulfills extra sustainability and quality criteria, set by a network of environmental NGOs. Using the ecolabel also helps consumers make a concrete and additional impact through our Climate Fund and Environmental Fund.
100Green launched the UK's first time-of-use tariff, TIDE in January 2017. Tide encourages customers to vary usage and consume electricity in periods of lower demand when the price is cheaper using an electricity smart meter.[4]
Generators
Only a few of 100Green's 650 generators were making electricity before 100Green was set up. The company's generators are all approved by Ofgem and have a large range of sources including energy from waste, biomass, photovoltaic-solar, small-scale hydro, wind, CHP and anaerobic digestion.
The company only buys green-sourced electricity and gas from within the UK and has no brown energy or nuclear in its business. 100Green facilitates investment into renewable technologies by creating demand for this green energy.
