We are installing interactive energy boards in our stores in the UK and Ireland.
The boards have an interactive touchscreen to show where the store is using energy in real time, allowing staff to take action.
They are projected to save 15,000 tonnes of CO2e, equating to a cost saving of £2 million, every year.
The energy boards won Best Energy Reduction Project of the Year at the Energy Event 2010, and helped Tesco win the Platts Global Energy Award for Best Energy Reduction Programme.
