A division of the U.S. Department
of Energy (DOE) known as the U.S. Energy Information Administration (EIA) is
reporting that Americans used less energy to heat and cool their homes in 2009
than they did in 1993, and energy efficient windows have contributed to
the reduction.
New survey results show the
energy used to heat and cool American homes dropped from 58 percent in 1993 to
48 percent in 2009. The amount of energy used for space heating alone
dropped from 53 percent in 1993 to 42 percent in 2009.
