Sainsbury's has pledged to power 100 of its supermarkets with underground renewable heat, after signing a deal with E.on and Geothermal International as part of efforts to slash its carbon emissions by 2020.
The supermarket chain announced two partnerships today that will see car parks in 100 of its larger stores kitted out with both geothermal power plants and ground source heat pumps designed to provide heating, hot water and cooling to stores.
