Over the last year, 50% of your electricity was used when the school was closed. The best schools use only 35% when the school is closed. Reducing out of hours electricity use is one of the easiest, and cheapest ways of saving lots of energy. Reducing your school's out of hours usage to 35% would save £760 per year.
What you should do
High out of hours electricity use is often caused by appliances which have been left on. These include:
- Old freezers and fridges running constantly
- Inefficient IT servers
- Security lights
- Electric water heaters
- Water chillers
- Air conditioning
- Computers, whiteboards and other electrical equipment left running when the school is closed.
Check to see what lights and appliances are left on at the end of the school day and get pupils and staff to switch off lights and appliances when they go home, and before the school holidays.
