4. Low Impact Living

The focal point of this well designed site is its Impact Calculator. The quiz-styles calculator helps you get a fix on your energy goals and design it around your lifestyle with the aim of reducing your total environmental impact. The calculator uses regional default values and gives you a customized profile that reflects the specifics of your home. The other resources on the site are on recommendations on green products and services. One of my favorite sections is Lowdown which tells us how people are living in green homes around the world.
