Energy efficiency is the cheapest method of providing Americans with electricity. Energy efficiency programs aimed at reducing energy waste cost utilities only about three cents per kilowatt hour, while generating the same amount of electricity from sources such as fossil fuels can cost two to three times more.

Our existing housing stock is an underutilized energy efficiency resource. We’ve only scratched the surface of its potential to save energy. Decades of research and thousands of retrofits show that even the most basic home retrofits can cut energy use by 15-20% while more comprehensive retrofit projects can double or even triple the energy savings. Residents benefit not only from lower energy bills, but also from improved comfort, better health, and safer, more durable homes. Despite the widely-documented benefits of whole home retrofits, demand for retrofits lags.
Approximately 518,000 retrofit projects were completed through the Home Performance with ENERGY STAR program from 2002-2015, according to DOE. Add to that the roughly 75,000 homes retrofit through the Better Buildings Neighborhood Program and the total number of home performance retrofits completed through the leading program efforts approaches 700,000—less than 1% of US single-family homes. While this number doesn’t include retrofits completed outside of programs or those conducted through weatherization efforts targeted to low- and moderate-income households, it does illustrate the need to scale up retrofit activity to capture the energy savings available.
Specific challenges include:
- Calculating accurate project-level savings estimates,
- Ensuring that upgrades are installed and perform as expected, and
- Encouraging public buy-in and participation in programs.
