Unplug your chargers when you're not charging. Every house is full of little plastic power supplies to charge cell phones, PDA's, digital cameras, cordless tools and other personal gadgets. Keep them unplugged until you need them.

Laundry
Adjust the water level on the machine so it is appropriate for the size of the load. Try to wash only
