NO1122 : A wind turbine for your store

From the Tesco website:

We’re doing more to use less energy
As part of our pledge to cut our carbon footprint, we have to cut our energy use. So we’ve made an important commitment: by 2020, we plan to have halved the carbon footprint of our global business compared to 2006.

We’ve halved our energy use since 2000!
Our UK stores use 50% less energy than they did in 2000. This year alone we have invested £86 million in energy-saving technology for our stores, including low-energy lighting, energy-efficient bakery ovens, wind turbines, combined heat and power (CHP), trigeneration and hanging curtains on freezer doors. These measures saved 66,000 tonnes of CO2 emissions.
