Buy those light bulbs that last forever at a store like home depot. I think they are called fluorescent and they are circular for lamps or they look like a stick for other appliances (compact fluorescent). I paid a lot of money for them years ago and they are still working after about 10 years. They also don't use as much wattage but throw as much light.
If you have an electric water heater, turn off the heater at the circuit breaker box when you don't need to use it. Flip it back on about 15 to 20 minutes before you want to wash the dishes or take a shower. I just put the kitchen timer on. The water stays warm for a long time and heats up fast. Saves about $10 on my electric bill each month. If you have company, leave it on all the time because there is too much confusion when they are there with showers and etc.
