Reorganize your refrigerator.

Let cold air circulate between items in your fridge, but pack things tight in the freezer.

Consider a cold wash.

Switching your temperature setting from hot to cold can cut energy use in half for washing one load.

Give your computer a rest.

Set your computer to go to “sleep” after 20 minutes of inactivity.

Use your dishwasher wisely.

Run full loads, avoid special cycles, and air-dry or towel off clean dishes.

Beware of vampire voltage.

Many electronics continue to draw power even when they’re turned off. Be sure to unplug devices when you’re done.

Switch off unneeded lights.

Lighting accounts for nearly 15% of energy costs. Last to leave? Turn off the lights on your way out the door.
