Passive Solar Lighting
One of the easiest ways to save money is by using passive solar lighting. Too many times we enclose ourselves in homes that provide shelter but then need an additional means to provide the light required to see what we are doing. By using the light from the sun, you can have the additional light required for your home to allow you to accomplish simple tasks during the day.
It won't help you very much when it gets dark as the sun goes down but it may help you from flipping that switch during the day that will cause the little dial on your utility meter to spin like crazy.
