Read the full story from U.S. DOE.
A working paper released in June by academics with the E2e Project wrongly suggested that the federal Weatherization Assistance Program (WAP) and other energy efficiency programs are not good investments. This result contradicts many past studies and was so surprising that the media was set abuzz.
Two new major, peer reviewed, national evaluations of WAP from DOE’s Oak Ridge National Laboratory (ORNL) provide fresh evidence that WAP is indeed a good investment with energy savings exceeding the costs by a factor of 1.4. The evaluations also show that under the Recovery Act, while achieving economic stimulus goals, the benefit cost ratio for WAP energy savings measures is estimated at just below 1, substantially better results than found by E2e.
