Fill Fridge:
A fridge full of food uses less energy than an empty one. That is because the food keeps the temperature from warming up too fast when the door is open. Chilled food= chilled fridge.
Power down:
Did you know that by powering down just one computer monitor and hard drive nightly and on weekends can save you up to $80 a year?
Unplug your chargers and other appliances when not in use. They are still drawing electricity even when not in use, so just teach yourself and your family to unplug and re-plug in your appliances when not in use.
Also put your devices into sleep mode settings when not in use to conserve energy, where ever you can.
