Saving on hot water

When you wash your hands, chances are that the water doesn't have a chance to get really warm before you're through. Since you're essentially washing in cold water anyway, don't even turn on the hot water. Traditional water heaters come on every time the temperature drops, and if the water in the pipes is cool, hot water replaces that awhile before it reaches the faucet, lowering the temperature and kicking on the water heater.

Leaking Electricity

TVs, microwaves, computers and anything else that has a clock or light that stays on (or an "instant on" feature) still use energy when they're turned off, so unplug them when not in use. If that isn't convenient, put them on a power strip and turn that off when you're not using the appliances.
