I recently took a class called Sustainable Solutions in school and I learned a lot about the importance of going green. Ever since then I been trying to change things around the house.
Some stuff I have changed are the water faucets, I changed them with WaterSense faucets and I am hoping my next water bill will be lower. I also bought a new energy star refrigerator from a free classified ads website and it's really amazing.
I am looking for some more ideas to go green, if there is something you changed about your house or you got an idea, please post it.
