This week, Erin shared the results of a major energy efficiency retrofit at her local library. Efficiency improvements over several years include installing 250 solar panels  on the roof, upgrading to energy-efficient lighting , and others. The library has been saving over $57,000 per year in electricity costs, and expects to save even more in the future.
After discovering a renewable energy project in our blogger's own community, we're curious: What energy-saving, innovative projects have you come across in your neighborhood?
