GREEN TARIFF ELECTRICITY

TECHNICAL & PRACTICE

This is electricity generated from renewable sources - i. e. wind, waves, tidal, hydro-electric, photovoltaic and biomass. There is an embodied-energy cost of the plant to each of these. Some suppliers also include electricity from CHP (combined heat and power) plants - these need checking for whether they are fuelled by renewables. Some suppliers are essentially marketing this 'green' electricity but others are investing in new generating sources, such as Ecotricity, which mainly sells electricity from wind, and Green Energy UK, which says that 50 per cent of generating plant is newly commissioned since it started in 2001. We couldn't find a tariff, though suppliers don't hide the fact that tariffs are higher than from conventionally generated electricity. These suppliers may also purchase surplus electricity where your own projects include electricity generation, e. g. from photovoltaics, wind or CHP. (Onsite electricity storage is usually very expensive. ) Jestico + Whiles and Feilden Clegg Bradley use Good Energy at www. good-energy. co. uk Architype uses Green Energy UK at www. greenenergyuk. com Atkins uses Ecotricity at www. ecotricity. co. uk which it sourced via British Gas at www. house. co. uk
