ASU faculty member Phillip Stafford challenges his colleagues to implement clean energy at home. Stafford shares how he’s achieved a $12 annual electricity bill for his 5,000-square-foot, Phoenix home. To get off the grid, Stafford recently upgraded the photovoltaic (PV) solar panels on his home that generate more than 12,000 watts of electricity. He also uses LED lights, has two hot water heaters, uses mostly battery-powered lawn tools and has planted dozens of desert shade trees around his house. Stafford says that the high, upfront costs definitely are paying off. Have questions for Stafford? Visit his ASU directory page.
