States lead by example (LBE) by establishing programs that achieve substantial energy cost savings within their own buildings and operations, and demonstrate the feasibility and benefits of clean energy to the larger market. This EPA guide identifies best practices and state examples of clean energy activities; highlights the benefits and costs of taking action; and identifies issues, strategies, and resources for implementing key steps in the development of a comprehensive LBE program. The appendices provide additional examples and information resources. The guide was created as part of EPA's State Climate and Clean Energy Program, which assists states in developing and implementing clean energy policies and climate change solutions.
