In recent posts I have referred to a number of sites with interesting and useful content. Another one worth a look is by Energy Star, a government-backed program for promoting energy efficiency. I like the way the home page is divided into sections so you can easily find information of interest. The main categories are products, home improvement, new homes, business improvement and partner resources. From two to six sub-categories are listed under each main heading. There are interactive features, too, where you can analyze the efficiency of your own home or find a store that sells qualified products. I got all excited when I saw a button labeled "Solutions to common problems," but it turned out to be about "home" problems and didn't include a solution for inept and bumbling police inspectors.
