An Auburn University study sheds new light on just how valuable shade trees are in reducing homeowners' electricity bills in hot weather.
Professor David LaBand in the Auburn University School of Forestry and Wildlife Services says electricity usage and costs will be 11.4 percent less if a house has just 17.5 percent heavy shade coverage. This is compared to a house with no shade.
LaBand said the 11.4 percent savings would equal $31 to $33 per month.
He added that for each degree you lower your thermostat you will save 3.3 percent on your power bill.
