Cool Things Off with a Thick Lawn
Can your lawn help you keep cool this summer? To find out, try a little experiment. After
the sun goes down, put your hand on your driveway or a sidewalk and feel how warm it is. Then,
to compare, put your hand on your lawn. It will be a lot cooler. While you think your lawn just
sits there looking pretty, in reality, it's a powerful cooling engine.
How Your Yard Cools Things Off
Grass helps block about 50% of the sun's rays from reaching the ground, keeping it much
cooler than pavement. The air above your lawn can be as much as 30 degrees cooler than it is
above your driveway. Add some landscaping around your house, and your yard can help you save a
whopping 50% on your air conditioning bills.
What Happens When There's No Lawn or Landscaping
If you ever watch the weather report on TV, you might notice that temperatures in town are
usually higher than they are in outlying areas. Cities have more pavement, so they bake,
creating what's called the Urban Heat Island Effect. This effect costs cities about $ 1 million
an hour in extra cooling costs during the summer. Putting more lawns and landscaping in town
could help everybody save money and feel more comfortable.
Feel Good About Working in the Yard
Next time you wipe your brow when you're mowing your lawn, remember how much it's really
cooling you off.
