Frequently Asked Questions

What is the rebound effect in energy efficiency?

The rebound effect refers to the phenomenon where increased energy efficiency leads to an increase in energy consumption. It suggests that when individuals or households become more energy-efficient, they may be inclined to use more energy or adopt new energy-intensive behaviors, offsetting some of the energy savings achieved.

What is the Weatherization Assistance Program?

The Weatherization Assistance Program is the largest residential energy efficiency program in the United States. It aims to improve energy efficiency in low-income households by providing funds for weatherization measures such as insulation, air sealing, and furnace improvements. The program helps reduce energy bills and make homes more comfortable.

What were the findings of the study on the Weatherization Assistance Program?

The study found that the upfront investment costs of the Weatherization Assistance Program were approximately double the actual energy savings achieved. The model-projected savings were also more than three times higher than the actual observed savings. This suggests that the program may not be as cost-effective as initially believed.

Did the study find evidence of significantly higher indoor temperatures in weatherized homes?

No, the study did not find evidence of significantly higher indoor temperatures in weatherized homes, which would indicate an increase in energy usage. This finding challenges the notion that increased energy efficiency leads to a rebound effect and suggests that other factors may contribute to the observed discrepancy between projected and actual savings.

What is the energy efficiency gap?

The energy efficiency gap refers to the disconnect between the projected energy savings and the actual energy savings achieved in energy efficiency programs or investments. It highlights the difference between the expected benefits of energy efficiency measures and the realized outcomes, and can help identify areas for improvement in energy efficiency policies and programs.

What does the study suggest about energy efficiency investments and their benefits?

The study suggests that energy efficiency investments may not be as beneficial as commonly believed. Despite the positive private returns and environmental benefits associated with energy efficiency, the costs of the Weatherization Assistance Program outweigh the benefits. The study challenges the conventional wisdom that energy efficiency investments pay for themselves and lead to emissions reductions.
