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 information refers to
