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 - 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...

Research Report - February 28, 2018

Many state regulatory commissions are engaged in proceedings to modernize the electric grid. These proceedings include a heavy focus on updating system planning processes to reflect growth in distributed generation and other technological advances. Our report examines current distribution system...

Regulatory Filing - February 27, 2018

The comments submission references the docket EPA-HQ-OAR-2017-0545, and urges EPA to consider energy efficiency in state guidelines for greenhouse gas emissions from existing electric utility generating units. Attached are seven ACEEE documents demonstrating the value of energy efficiency in the...

Research Report - February 21, 2018

Pollution from power plants harms public health, contributing to heart attacks, respiratory conditions, asthma attacks, and premature death. Energy efficiency can benefit health by reducing power plant pollution. This report estimates the health and environmental benefits that would come from a...

Research Report - February 13, 2018

Electric vehicles (EVs) have the potential to reduce US transportation-sector energy use and associated emissions, as well as to support the transition to a more sustainable transportation system. Large-scale EV adoption will also create opportunities and challenges for the electric power sector...

Fact Sheet - February 12, 2018

Federal energy efficiency programs have played a key role in reducing energy use and saving consumers hundreds of billions of dollars a year in energy bills. But, like many other federal efforts, these programs have come under budgetary attack. This series of fact sheets estimates some of the...
