"Evidence of Rational Market Valuations for Home Energy Efficiency."

Study conducted by the United States Environmental Protection Agency showing the value of a home increases anywhere from $10 to $25 for every $1 reduction in annual fuel bills resulting from energy efficiency steps or the installation of solar energy equipment.

October, 2010 Update: Because this material was becoming dated, we contacted The Appraisal Journal to check on the validity of the information. The Appraisal Journal and the article authors confirmed this information is still as applicable today as it was when the study was conducted, and even more so given the increased cost of energy since the study was published.
