April 26 is National Arbor Day
Beautify your world: Plant a tree
Arbor Day is a nationally celebrated observance founded by J. Sterling Morton of Nebraska in 1872.
Trees are an energy-saving home improvement. They can be as important to energy conservation as insulation or weather-tight windows and doors. They save energy by cooling with shade in the summer and providing a windbreak in winter. Three strategically placed shade trees can reduce air conditioning costs by as much as 30 percent.
Deciduous trees shed their leaves during the winter. They provide shade and block heat during hotter months. By dropping their leaves in the fall, they admit sunlight in the colder months. Place these trees on the south and west sides of buildings. Shade hard surfaces such as driveways to minimize heat load.
Evergreens retain their leaves or needles throughout the year. As windbreaks, they can save a significant amount of the energy a home uses for heating. Place them on the north side of your home. Evergreens also provide shade in the summer.
