Using trees to beat the heat, naturally.
Can shade trees lower energy bills?
Yes, say the experts, and by quite a bit.
One study showed that mature trees properly placed around buildings can reduce air-conditioning needs by 30 percent and heating needs by 20 percent. Another study showed that planting one young tree on the west side of your home can cut energy costs by 3 percent within five years, and nearly 12 percent within 15 years!
