The Rhode Island Department of Environmental Management (DEM) is partnering with local environmental groups to give away 1,000 free trees to residents. Starting April 7, residents can register for the Energy-Saving Trees program via an interactive tool on the DEM website. After mapping their home, residents can choose from a variety of available tree species and sizes. Trees can be picked up at four locations on specific dates in April and May, and each tree is about four to six feet tall. Planting just one tree in the right place can reportedly save homeowners up to 20% on energy bills by providing shade in the summer and protection from wind in the winter. Additionally, planting trees can improve air quality and reduce stormwater runoff.
