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...

Fact Sheet - November 08, 2017

Millions of people work to save energy in the United States. They work in every state, across industries and technologies. To show the diverse arc of this growing workforce, we visited North Carolina. This fact sheet tells the stories of some of these workers—from manufacturers to builders,...

Fact Sheet - October 25, 2017

This fact sheet summarizes and illustrates the findings of a more detailed ACEEE study that looks at 13 packages of energy efficiency measures that together can reduce US 2040 energy use by 34% and US carbon emissions by 35%, putting us on a path to 50% savings by 2050. The packages cover...

Research Report - October 24, 2017

Energy efficiency is a powerful tool for lowering the disproportionate energy costs faced by low-income customers. Unfortunately, lack of capital, lack of credit, and aging housing stock that may need health and safety improvements often prevent these consumers from taking advantage of low-...

Research Report - October 18, 2017

EM&V (evaluation, measurement, and verification) plays many critical roles in planning, developing, and deploying energy efficiency utility system resources—and those resources are evolving. This report identifies the states that are showing policy and institutional leadership in EM&V...
