Computer simulations of
annual cooling savings for an energy efficient
home in the Southwest show that a typical household
spends about $250 each year for air conditioning.
Shade from two 25-foot tall trees on the west
and one on the east saves $57 a year, or 23%.
Reduced energy use results in lower utility
bills, less consumption of non-renewable resources,
and fewer emissions released into the atmosphere.

California Energy Study
A recent study at the Center found that
planting shade trees could reduce the
need for power plants. Data from California
shows that 50 million shade trees planted
in strategic, energy-saving locations
could eliminate the need for seven 100-megawatt
power plants. "Shade tree programs
can be a very cost effective measure for
conserving energy, especially peak load
demand," says Dr. Greg McPherson.
"Strategically locating trees to
shade west walls and windows in climate
regions where the benefits are highest
will save energy dollars and postpone,
if not eliminate, the need for some power
plants."
