3. Expanding the Urban Forest and Saving Energy
Washington DC needs 40,000 more acres of healthy tree cover to meet climate goals and federal air and clean water agreements. Residential yards are among the most promising available land for new canopy. In addition, siting new trees correctly near buildings reduces energy use. When building owners reduce energy use, power plants can lower emissions and fight global warming.
How to plant trees to save energy
For most shade, plant trees on the southwestern and western sides of buildings.
Plant on southeastern and southern sides for shade from morning sun.
Evergreen trees on northwest and northern side can shelter building from winter wind.
