We have to keep most of our biological samples at -80°C which is much colder than the -20°C you’ll find (hopefully) inside your freezer in the kitchen. This does require a lot of electricity.
Valentina put in an application to the Freezer Challenge and we came 19th out of 115 teams and won a Recognition Award! By increasing the temperature slightly on our freezers we estimate we will save 48kWh each day which is enough to boil an astonishing 436 litres of water.
And yes, that freezer is called Oprah…
