  6. 6. Project Phases PHASE I: Issue Identification and Assessment (September – November 2011) GOAL: Meet with stakeholders to identify issues of concern regarding the siting  and management of land‐based renewable energy. Identify existing research and  data. Understand past renewable energy efforts. PHASE II: Information Synthesis and Communication (December 2011 – January 2012) GOAL: Provide technical responses to the issues of concern identified by the  stakeholders during Phase I. Communicate to stakeholders the findings and  opportunities for continued engagement.
