Quick tips for reducing usage
- Turn off computers or use “sleep mode” when not in use. It is a common misconception that the equipment will last longer if
it is never turned off. This incorrect perception carries over from the days of older mainframe computers.
- Unplug laptop battery chargers when not in use. Even after being fully charged, laptop adapters continue to draw power.
- Many appliances continue to draw power when they are switched off but still plugged in. In the average home, 75% of the electricity
used to power home electronics is consumed while the products are turned off. Unplug the appliance or use the switch on a
power strip.
