ACEEE State Energy Efficiency Scorecard: ID, FL, VA Three Most-Improved States, MA Still #1

Washington, DC—As more states struggle with extreme weather events, the 2017 State Energy Efficiency Scorecard gives state-level policymakers a road map for building stronger and more-resilient communities. This 11th annual report from the American Council for an Energy-Efficient Economy (ACEEE), released today, shows which states are doing the best on energy efficiency — a critical tool for withstanding and recovering from storms and economic shocks.

Can the US cut its energy use in half by 2050? Yes, but we will have to double down on our efforts.

Five years ago, ACEEE found that energy efficiency could reduce projected 2050 US energy use by 40–60%. As a result, ACEEE established a strategic goal to reduce projected 2050 energy use by 50%. We thought it was time to check on our progress and ask whether our goal still seems reasonable. We find that energy use has been stable in recent years, reversing historical growth, a very positive development that is due in significant part to increasing our energy efficiency.

Mobile homes move toward efficiency

Do you know which government in the United States is the biggest laggard on energy codes for homes? The federal government. But that’s about to change.

Manufactured homes and the “HUD Code”

Although building codes are mostly set by states, the federal government sets codes for manufactured homes (sometimes called mobile homes) because the factory does not always know where a home will end up. Manufacturers shipped 70,519 homes in 2015, more than the number of single-family homes built in any state except Texas.

Take a ride on the energy slide with building codes

Building codes have protected people with minimum health and safety requirements for buildings since the Code of Hammurabi in 1754 BCE. Energy provisions in US codes have protected owners and tenants from excessive energy waste since the 1970s. They set minimum performance levels for energy features in new buildings and renovations, notably insulation, windows, air sealing, and to some extent, lighting and heating and cooling equipment.
