This document summarizes a study examining the economic benefits of investing in low-income energy efficiency programs. The study finds that for every $1 million invested in low-income energy efficiency programs across Entergy jurisdictions, there is an increase in economic output of $23 million and 216 jobs are created. In comparison, a $1 million public investment to attract manufacturing yields $8.6 million in economic output and 71 jobs. The study concludes that investing in low-income energy efficiency is a powerful source of economic development that is almost three times more effective than alternatives like attracting manufacturing and should be a key part of economic development strategies.
