The John Lewis Partnership is to ramp up its green credentials by getting all of its electricity and gas from renewable sources by October 2007. The decision will cover energy usage in its 26 department stores, 183 Waitrose supermarkets and its head office.

EDF Energy will supply the retailer. Around half of the energy is expected to come from small-scale hydro-electric generation, with the other 50% coming from a combination of biomass, landfill gas, tidal power and on-shore wind.

JLP currently gets around 40% of its energy from renewable sources.
