ENERGY STAR is a government program (public/private partnership) that gives
people the power to protect the environment in a cost effective way and without
sacrificing quality or product features. Products that earn the ENERGY STAR
prevent greenhouse gas emissions by meeting strict energy efficiency guidelines
set by the US Environmental Protection Agency (EPA) and the US Department of
Energy (DOE). In the average home, 75% of all electricity used to power home electronics is
consumed while the products are turned off. ENERGY STAR qualified home electronic
products in the off position use up to 50% less energy than conventional equipment. More
