Captain, My Captain

I took a carbon output test to see how environmentally friendly we are. My family scored a 348. I couldn't seem to find whether that is average, high, or low. I know we could score better. For instance, we don't have all halogen bulbs, just some. They are expensive, so as bulbs burn out, we replace them with halogen. So that one will get better.

As we settle in, I'm thinking more green. Growing up, we had rotating chores. One of the chores was the light captain. This person was responsible for going around to rooms and making sure the lights were out. I am going to do that here. That would help our green rating, besides saving on electricity.

I wonder what the average family can do to be more green without spending a ton of money?
