In this completely revised and expanded edition, the advances in science and technology shine brightly to walk homeowners through the many solutions for basic energy, airflow problems, heating and cooling systems, appliances and lights, mixed climate issues and alternative energy strategies that are doable and extremely efficient. With "Insulate & Weatherize" at hand, home energy costs won't soar through the roof, especially if there's a solar panel on it.
