We rely increasingly on energy produced from renewable energy sources. For example, we have installed a modern wood cutting plant with flue gas scrubbing, which we use for the supermarket and the restaurant at the Muripark shopping centre in Muri. Compared with the use of conventional oil heating, we thus save 90 tonnes of CO2 each year.
We have also installed over 60 photovoltaic systems on our buildings, with a total output of 11 250 kilowatts. These systems produce around 15 million kilowatt hours of solar electricity each year: enough to meet the average annual electricity requirements of about 4 500 Swiss households. This environmentally friendly electricity has been used by our points of sale since 2016.
