Speaking of simple ways to make your home more energy efficient - consider your lights.  Proper lighting as well thoughtful care and selection of your lights can make your home even more energy efficient.  When it comes to lighting in your home, consider the following:

1) Avoid opaque light shades that require stronger bulbs.

2) Use light paints and flooring to reflect light.

3) Clean and dust light fixtures so their light will shine through. 

4) When reading or performing tasks requiring focused lighting, turn off background lights and rely instead on a small focused lamp.
