How to make your home more energy efficient
This page lists different home energy retrofits that can improve energy efficiency in standard US homes. Many people in the United States live in homes that were built in the last century. According to the EPA, homes built before the 20th century were generally more efficient.  There are many ways you can save money and energy in your home. The Homeowner's Guide to Saving Energy.
Start with a home energy Audit
A home energy audit is a way in which you can actually look at what areas of your home you are using, and possibly losing energy. While you could always hire a professional to do this, we recommend you learn how to do this yourself and learn how to do it right. It is your home we are talking about. Here is a good website that talks about a lot of the things you should keep in mind when doing a home energy audit.
