Research Report - June 13, 2017

This first edition of the Utility Energy Efficiency Scorecard assesses the 51 largest US electric utilities across a range of energy efficiency metrics. The metrics fall into three categories critical to utility-sector efficiency: (1) quantitative savings and spending performance, (2)...

Fact Sheet - March 01, 2017

How large is the energy efficiency “industry”? At least 2.2 million people work in whole or in part on energy efficiency in the United States. If supporting jobs and jobs due to energy savings are included, the total is at least three times as large. The jobs are spread in multiple sectors and...

Research Report - April 20, 2016

Energy burden is the percentage of household income spent on home energy bills. In this report, ACEEE, along with the Energy Efficiency for All coalition, measures the energy burden of households in 48 of the largest American cities. We find that low-income, African-American, Latino, low-income...

Fact Sheet - October 27, 2015

Lowering the amount of energy we waste reduces our need to burn coal and other fossil fuels to generate electricity. Those reductions in pollution mean big gains for health, as pollutants from fossil fuel combustion contribute to four of the leading causes of death in the United States: cancer,...

Research Report - June 14, 2018

Local governments across the United States are increasingly enacting policies and offering programs to drive energy savings, but the success of these activities is inextricably linked to a strong, capable energy efficiency workforce. To ensure that trained workers are available to capitalize on...

Fact Sheet - June 05, 2018

Highly efficient air conditioners and heat pumps use superior mechanical efficiency and advanced controls to save building energy. This equipment can provide energy efficiency program administrators with long-term energy savings. In these technical briefs, ACEEE provides an analysis of the...

Testimony - May 31, 2018

The comments refer to a May 18 Science Advisory Board Work Group memo. 

Research Report - May 02, 2018

A growing number of housing providers, utility-sector program administrators, and investors are working to combine energy efficiency improvements with solar systems in affordable multifamily buildings. Pairing energy efficiency with rooftop solar systems can reduce energy costs for these...

White Paper - April 25, 2018

In this paper we examine how decision makers can more precisely assess the costs of disruptive weather events and the value of resilient distributed energy systems such as combined heat and power (CHP). CHP makes up a small percentage of the energy infrastructure in the United States despite its...

Research Report - April 16, 2018

Homeowners and renters are increasingly using technologies like smart thermostats and smart lighting, appliances, and outlets to enhance comfort and convenience. But these are not the only benefits. Smart technologies can also optimize a home’s energy use, reducing waste and lowering utility...

Research Report - April 16, 2018

State air regulators can rely on energy efficiency to help meet specific pollutant reductions required under the EPA’s National Ambient Air Quality Standards (NAAQS). However many states are not incorporating this compliance strategy into their state implementation plans (SIPs). This report...

Research Report - April 10, 2018

Wholesale energy prices have historically been volatile, and this can impose significant costs on electricity buyers and sellers. This report examines these costs in electricity markets and demonstrates the value of energy efficiency as a low-risk supply option. It estimates the value at risk in...

Regulatory Filing - April 09, 2018

Comments delivered to the Virginia Department of Environmental Quality RE: Rev. C17, 9VAC5 Chapter 140. 

Research Report - March 26, 2018

ACEEE’s Health and Energy Linked (HELP) Awards recognize programs that simultaneously improve human health and save energy. This report highlights the six exemplary programs chosen by a panel of expert advisors to receive the first awards. Case studies describe funding, communities served, and...
