Adding doors to open fridges and freezers – a simple way to save energy?

Supermarket fridges are a regular sight in our weekly shop, but use a lot of electricity. Estimates suggest they represent 1% of the entire electricity output of the United Kingdom.

The open design allows us to easily pick up our shopping, but equally allows cold air to escape, meaning the fridges effectively have to cool down the whole shop. Research suggests that changes to these cabinets could save as much as 40% of the electricity they use.

Tackling climate change requires improved efficiency of appliances and it is the responsibility of organisations to take steps to improve efficiency. Supermarkets are reluctant to make a change as they feel it could impact sales. Pressure is needed to introduce legislation so that all are forced to improve the efficiency of these appliances.
