Study: Shade trees lower bills, emissions
Sacramento (UPI) Jan 6, 2009 Shade trees on the west and south sides of a house in California can reduce summertime electricity use and reduce carbon emissions, a study indicates. The study conducted last year on 460 single-family homes in Sacramento, is the first large study using utility bill information to demonstrate that trees can reduce energy consumption, the U.S. Agriculture Department's Forest Services said in a news release. "Everyone knows that shade trees cool a house. No one is going to get a Nobel Prize for that conclusion," says study co-author Geoffrey Donovan. "But this study gets at the details: Where should a tree be placed to get the most benefits? And how exactly do shade trees impact our carbon footprint?" Donovan, a research forester with the Forest Service's Pacific Northwest Research Station, co-authored the report with economist David Butry of the National Institutes of Standards and Technology. Their findings have been submitted to the journal Energy and Buildings. Related Links Powering The World in the 21st Century at Energy-Daily.com
