Sainsbury’s announced today it will power 100 of its stores with underground renewable heat as part of its efforts to cut carbon emissions by 2020.
The supermarket chain signed agreements with E.ON and Geothermal International, in which both companies will install geothermal heat pump technology at the stores to provide energy efficient heating, hot water and cooling. It claims this will reduce each stores’ carbon emissions and energy consumption by up to 30% each.
The scheme is part of Sainsbury’s 20 by 20 Sustainability Plan renewables commitment, which includes reducing its carbon emissions by 30% and delivering a fully renewable heat strategy for its supermarkets within the next two decades. The company also aims to deliver up to 100MW of renewable energy sources in its stores by 2016.
Neil Sachdev, Sainsbury’s Property Director said: “The roll out of this technology with our partners is an important milestone in our renewables commitment. It supports job creation in the renewable energy sector and our goal to reduce our absolute operational carbon emissions by 2020, as well as delivering energy cost savings for our business.
“We’ve also reduced our absolute electricity usage in supermarkets by over 9% in the past four years despite an increase in space.”
The company is already using geo-thermal technology at its Crayford store, which it claims supplies 30% of its energy from on-site renewable sources.
