Why can't Massachusetts do this? http://online.wsj.com/article/SB125064722656442071.html I know a contractor who has started a business doing energy audits and I am going to ask him to guest blog. Now we just need local loan programs to defray the costs of doing energy-saving retrofits. At the end of the day, the homeowner is saving money by improving the environment, the contractors are getting much-needed work, and everybody benefits.
