The school purchased plug-in monitors to check the daytime and overnight power consumption of appliances and equipment. Each item was monitored over 2 days and readings taken at 9am and 3pm for each item. Items monitored included fridges, freezers, photocopiers, laptop and IPad chargers.
Freezers and photocopiers were the heaviest users of electric, even overnight. Laptop and IPad chargers used very little power, some were so low they did not register.
