We've all known for quite a while that trees that shade our homes can lower our utility bills, but now we have proof. A study by the US Forest Service has determined how and where to plant trees for the greatest benefit on energy savings. Find out more and see an informative video after the jump.
The Mother Nature Network sums up the findings of the study:
He found that trees placed on the south and west side of a house, and no more than 60 feet away from the actual building, could lower a homeowner's utility bills by about 5 percent between May and September. However, trees on the north side actually raised their bills by 1 percent. Why? Because on that side of your house, trees act more like blankets than shade. "They slow radiant cooling of the house at night," Donovan says, "and they don't cast any house-shading shadows." So they cost you some cooling after the sun goes down, without sparing you some heat during the day.
