This Interim Report provides the results of process evaluation activity undertaken to review the MAPC's Clean Energy Division's first year of operation (July 2011-June 2012). MAPC proposed to support cities and towns within the MAPC region to focus on clean energy and energy efficiency. Their theory of change involves recognizing that cities and towns are interested in developing their own clean energy solutions but lack the internal technical and logistical capacity to identify, develop and implement best practices and programs. MAPC proposed to fill this gap with a range of technical assistance, collective procurement, regionalization and policy projects. The evaluation found that the MAPC intervention identified significant potential energy savings and greenhouse gas reductions, and strategies to realize these savings.
