This week, you read about Chris' experience with frozen pipes, and how he saved money with a simple do-it-yourself (DIY) project. While not every project is suitable for do-it-yourself (some of them really do require experienced professionals), sometimes DIY really is easy and can amount to significant savings.

What do-it-yourself projects have saved you energy and money?

Each Thursday, 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.
