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?

Each week, you have the chance to share your thoughts on a question about energy efficiency or renewable energy for consumers. Please comment with your answers, and also feel free to respond to other comments.
