Energy efficiency can slash US energy use and greenhouse gas emissions by about 50% by 2050, getting us halfway to our national climate goals. We can achieve almost all these savings, worth more than $700 billion in 2050, by dramatically scaling up government policies and programs. This report...

Research Report - September 10, 2019

Programs that integrate energy efficiency and demand response (EE/DR) can yield multiple benefits. Not only can they fully capture these two value streams, but they offer a streamlined customer experience, greater grid flexibility, and more efficient administration. Despite these benefits, few...

Research Report - July 30, 2019

Energy efficiency resource standards (EERS) have been a key tool for delivering energy savings in states across the country. Now states are looking to their energy efficiency policies to do more. New approaches to EERS can help them meet aggressive climate goals, lower costs, improve grid...

Research Report - July 24, 2019

The City Clean Energy Scorecard measures the progress of city policies and programs that save energy, promote renewable energy, and reduce greenhouse gas emissions. It also focuses on efforts to embed equity in policymaking. We ranked 75 large US cities for their energy efficiency and...

Research Report - April 11, 2019

Tens of thousands of home energy assessments are conducted every year in the United States, but many recipients do not follow through on their recommendations. We studied 45 sample assessment reports by coding them for design and content elements, sending them for review by a panel of experts (...

Research Report - April 09, 2019

Energy efficiency programs have historically underserved multifamily housing for low-income households, largely because of the barriers this market presents to program administrators. This report examines 32 programs that target affordable multifamily buildings, focusing on energy savings,...

Research Report - February 20, 2019

The lifetime of energy efficiency programs and measures ranges from a few months to several decades. Nevertheless, most energy efficiency policies are designed around the first year of savings. This report describes recent policy changes in some states and Canadian provinces to measure the value...

Research Report - January 16, 2019

ACEEE has reviewed exemplary customer-funded electric and natural gas utility programs every five years since 2003. For this edition of the report, we solicited nominations nationally and analyzed them in collaboration with an independent expert advisory panel. We ultimately selected 53 models...

Research Report - January 09, 2019

Energy efficiency programs built around strategic energy management (SEM) can help the workforces of large organizations identify energy-saving opportunities, implement improvements, and track reductions in usage. Programs can also offer another tool, energy management information systems (EMISs...
