Residential energy efficiency can benefit consumers through reduced utility bills, and support national environmental policy objectives by reducing the demand for electricity generated using fossil-fuels and reducing current strains on the electric power grid. Various policies to increase conservation and energy efficiency have been adopted since the 1970s, including tax incentives. Developing and deploying technologies that are consistent with the most efficient use of our nation's energy resources is broadly appealing. This book explores tax credits as a means of promoting residential energy efficiency. It also provides insight on energy conservation and climate changes.
