Shade trees can save you
money on your energy bill. Now,
for the first time, researchers
have figured out just how much.

Economists looked at utility bills of homes in California on the hottest days
of the year.

Geoffrey Donovan is with the Forest Service Research Station.

He says, if you have shade trees on the south or west sides of your home,
those trees reduce your electricity use by five percent.

“So putting a tree somewhere it’s going to cast shadows at the warmest time
of the day. The other thing you want to think about is winter sunshine.
Particularly on the south side of a house you may want to put a deciduous
tree as opposed to an evergreen tree so in wintertime you’ll get some
sunshine through that.”

Donovan says how close you put those trees to your house matters too. For
the most energy savings, shade trees should be within 40 to 60 feet of your
home.
