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...

Research Report - June 25, 2018

The 2018 International Energy Efficiency Scorecard examines the efficiency policies and performance of 25 of the world’s top energy-consuming countries. We used 36 metrics to evaluate each country’s national commitment to saving energy as well as its efficiency policies and performance...

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...
