Trees can lower your energy bill

Planting specific types of trees can reduce utility bills, per the “Iowa Climate Statement 2022: The Many Benefits of Our Trees.” The statement said a Midwest electric utility explains that the proper placement of just three trees can save an average household between $100 and $250 in energy costs annually. 

“Attention to the species of trees we plant and their care will be crucial for their survival. Strategies are needed both to sustain the many benefits of existing large mature trees and to increase planting of appropriate new trees for mitigating and adapting to climate change,” said Jan Thompson, Morrill Professor, Natural Resource Ecology and Management, Iowa State University. 

Trees can provide shade, block the sun, and keep the interior of homes cool. In addition, through a process called transpiration, trees lose water vapor to cool the environment. These processes combined create a lower energy bill for homes. 

In the summer months, plant deciduous trees where direct light enters a home. Deciduous trees have leaves in the summer, but lose them in the fall, allowing sunlight to naturally warm a house in the colder months. During the winter, planting evergreen trees on the sides of houses can stop the wind from entering through a house’s gaps and cracks.
