Working from home and energy use
Heating and cooling
Around 40% of home energy use can go on heating and/or cooling.
Shut doors to unused areas. Only heat or cool the rooms you’re using.. Set your heating between 18°C and 20°C and your cooling between 25°C and 27°C.
For every degree you increase heating and cooling, you increase energy use between 5% and 10%.
Dress comfortably. You may need to look professional from the waist up for virtual meetings, but working from home means you can dress for the season.
Close any applications you’re not using.
Don’t use active or animated screensavers.
Ensure air vents on computer towers and laptops are kept clear and away from objects. Excess heat makes your computer work harder and can lead to system failures.
If purchasing new monitors, look for the
The more stars the better. Energy Rating Label. Laptops, ultrabooks and notebooks use less energy than desktop computers and can be battery-operated for extended periods.
Reduce screen brightness to the lowest setting that’s comfortable for your eyes.
Set your monitor to switch off/sleep after 10 minutes of inactivity.
Switch off Bluetooth and Wi-Fi when you’re not using them as they use a substantial amount of power by constantly searching for a signal.
Switch off when you’ve finished using your device, or set a timer.
Unplug any USB devices (like mice, keyboards, speakers and flash drives) when not in use.
Put the laptop charger on a powerboard that can be switched off, or turns off automatically. The charger draws power continuously, even when the laptop is not plugged into the adapter.
Delete unwanted applications. The more applications your smartphone has, the faster the power will drain.
Reduce screen brightness and turn off live (animated) wallpapers to reduce battery drain.
Set your notification alerts to check at 30 minute intervals (or longer) and close applications when you don’t need them. This can also make a big difference to your data usage.
Shorten the amount of time for the screen to turn off automatically—try 30 seconds.
Switch off Bluetooth, GPS and Wi-Fi connections when not in use as they use a substantial amount of power by constantly searching for signal.
Switch off chargers at the wall once charging is complete, and avoid charging overnight if you can.
Switch to aeroplane mode where applicable.
‘Think before you print’ and opt for a printer that prints on both sides of the paper—saving both time and resources.
Turn off your printer, copier, scanner and multi-function devices when not in use.
