MARCH 2010 SOLAR ANN ARBOR A PLAN FOR ACTION ACKNOWLDGEMENTS Funding for this project was provided by the U.S. Department of Energy. This Solar Plan was written in 2009, and published in March 2010 by Clean Energy Coalition authors Lisa Dugdale, Robyn Skodzinsky, and Greg Vendena. Additional writing and research was completed by Clean Energy Coalition volunteers Anika Fassia, Parvathi Krishna Kumar, and Matt Miller. Cover design was done by Invisible Engines. ABOUT THE U.S. DEPARTMENT OF ENERGY’S SOLAR AMERICA CITIES PARTNERSHIP The U.S. Department of Energy Solar America Cities partnership supports 25 U.S. cities com- mitted to making solar a mainstream energy source. DOE provides financial and technical as- sistance to expand innovative efforts to accelerate the adoption of solar energy technolo- gies. Cities, the nation’s centers of electricity consumption, are uniquely positioned to re- duce global climate change, strengthen America’s energy independence, and improve air qua- lity by converting to solar energy sources. From installing solar on city facilities to up- dating zoning codes and permitting processes to providing financial incentives, Solar America Cities demonstrate comprehensive, city-wide approaches that encourage and facili- tate solar as a viable energy solution for residents and businesses.

Through implementing this plan, policy changes to be most effective. The benefits Ann Arbor will serve as a model for other communi- described in this Plan include: ties looking to solar energy as an answer to rising en- • Environmental Benefits ergy costs, unstable energy supplies, stagnating local • Public Health economies, and the negative environmental impacts of nonrenewable energy
