Research Report U1907 - September 18, 2019

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 U1904 - 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 U1902 - 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 - 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

Updated March 2019. 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...

Testimony - February 06, 2018

Testimony delivered by Dr. Martin Kushler to the Kansas Senate Utilities Committee entitled "Information to Support Effective Energy Efficiency Policy in Kansas."

Research Report - January 24, 2018

Energy production and consumption require water, and water transport and treatment need energy. Researchers and practitioners are increasingly interested in designing integrated programs to manage energy and water in tandem. Utilities typically do not focus on the avoided costs and indirect...

Research Report - December 20, 2017

Commercial buildings have their own unique energy systems, ownership structures, and decision-making processes. They also have striking opportunities to save energy by installing smart technologies. Beginning where our previous Smart Buildings study left off, this report takes a deeper...

Research Report - December 13, 2017

Market transformation is a program model for achieving long-lasting changes in targeted markets to increase shares of energy-efficient products and services. This report examines recent market transformation efforts to identify keys to successful programs and the challenges they face. We...

Description of utility-sector energy efficiency opportunities in Virginia, using data from ACEEE’s 2017 Utility Energy Efficiency Scorecard.

Research Report - December 06, 2017

Regional transmission organizations use capacity auctions to ensure energy resources are available to meet future demand. This report synthesizes and analyzes data on energy efficiency in two annual capacity auctions: PJM and ISO New England. Focusing on results since the inception of both...

Research Report - November 27, 2017

In this report, we discuss how information technologies and communication networks are enabling new ways of tracking and analyzing the many benefits of saving energy. When stakeholders can quantify the coincident benefits of energy savings and put monetary value on them, they improve the...
