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...

Research Report - November 14, 2018

Municipal governments are increasingly using behavior change strategies to save energy in their communities. For this study we surveyed cities across North America and analyzed 50 behavior change programs offered by 40 local governments in 18 states and Canada. Our report provides an overview of...

Research Report - October 29, 2018

Energy efficiency supports the reliability and resilience of our electricity system. However, these benefits are typically not included in electric system planning, decision making, and cost-effectiveness analysis. This report examines energy efficiency's contribution to reliability in terms of...

Research Report - October 04, 2018

The twelfth edition of the ACEEE State Energy Efficiency Scorecard gives a progress report on state energy efficiency policies and programs that save energy and produce environmental and economic benefits. The Scorecard uses data vetted by state energy officials to rank states...

Research Report - September 19, 2018

Rural communities have unique energy needs that make it challenging for utilities, state energy offices, and other program implementers to deliver energy efficiency to customers. Infrastructure, energy use, and fuel mix in rural areas often differ from their metropolitan counterparts. Rural...

National appliance efficiency standards drive energy, water, and utility bill savings. They are also major job creators. Existing standards could help consumers save $2 trillion on energy bills by 2030, money that will create new jobs when shifted from utilities to other goods and services. This...

Research Report - July 18, 2018

In this report, ACEEE and the Energy Efficiency for All coalition examine residential energy affordability in rural and small-town America and identify energy efficiency as an underutilized strategy that can help reduce energy burdens by as much as 25%. We analyze how rural energy burdens―the...

Research Report - July 10, 2018

To achieve the ambitious worldwide goal of reducing greenhouse gas emissions 80% or more by 2050, consumers and businesses will increasingly need to use heat pumps powered by low- or no-carbon electricity for space and water heating. But does electrification make sense for homeowners considering...
