The Winter Vacation is almost here! Before you head off, do your bit to cut energy use and make campus more sustainable. It really makes a difference!
Saving energy
Over the past year, the University has consumed an average of 120,559 kWh of gas and 48,549 kWh of electricity per day - enough to heat around 3,827 homes per day or enough power to make 693,557 cups of tea! Every energy-saving action - big or small - helps create a more sustainable campus and supports a healthier planet.
Your switch-off checklist
Whether you live on campus or in private accommodation, the following actions will help save energy and reduce costs:
Lights and windows
- Turn off all lights
- Close windows
Heating and cooling
- Set radiators to frost (star setting *)
- Switch off heaters
Electronics and devices
- Power down laptops and monitors
- Turn off TVs completely (standby doesn’t count!)
- Unplug chargers and small devices
- Switch off anything else using power
Every small action counts! Thank you for helping us reduce energy use and make our campus more sustainable over the festive break.
