When properly planted and well cared for, trees can trap and hold rainwater in their leaves, branches, bark and root systems. This allows the water to filter slowly into the ground so it can percolate (seep) down and replenish groundwater supplies.
In addition to their water conservation benefits, trees can reduce your electric bill and the need for imported electricity from coal (or gas)-fired power plants. (Read more about the benefits of trees.)
TreePeople recommends planting trees on the east and west sides of buildings to shade air conditioners. When planted on the south side, deciduous trees (trees that lose their leaves in the fall) shade buildings in the summer and let the sun's warmth come through in the winter.
