Don't overlook the value of landscaping in summer energy savings. About 60 percent of the heat entering a home in the summer is through the roof. Provide shade to the roof, walls and driveways to reduce heat absorption and save energy and money. Take advantage of windows in the spring for fresh air and natural ventilation. In the summer,keep the drapes drawn to reduce radiant heat from the sun.
Ventilation is especially important to reduce summer energy costs.
Make sure attics are properly ventilated. Change air conditioner filters regularly. Insulate air conditioner ducts that are exposed in the attic or in other areas. If you buy new appliances, look for energy saving features. Check the energy guide on appliances for energy consumption.
