We estimated the effect of shade trees on the summertime electricity use of 640 single-family homes in Sacramento, California. Results show that trees on the west and south sides of a house reduce summertime electricity use, whereas trees on the north side of a house increase summertime electricity use. Current level of tree cover on the west and south sides of houses in our sample reduce summertime electricity use by 185 kWh (5.2 %), whereas north-side trees increase electricity use by 55 kWh (1.5 %). Results also show that a London Plane Tree, planted on the west side of a house, can reduce carbon emissions from summertime electricity use by 31% over a 100-year horizon.
