As of 2002, there are 240,000 community associations–condominium associations, cooperatives, and homeowners associations–in the United States, representing nearly 20 million homes and 45 million people. Currently, the average U.S. family spends nearly $1,300 a year on energy bills, with much of that energy being wasted due to air leaks, inefficient appliances and a general lack of attention on this important issue.
