Research Report E1501 - April 21, 2015

EPA’s Clean Power Plan allows states to pick from many pollution-reducing technologies and policies—including energy efficiency—when designing their compliance plans. What are the costs and emissions benefits of these various compliance options? ACEEE has developed the State and Utility...

Research Report A1501 - January 27, 2015

This paper describes recent advances in energy-saving elevator technologies and recommends a path for accelerating the uptake of these new capabilities. New building codes are stimulating the adoption of modern systems that can save more than 40% of current annual energy use. ACEEE recommends...

Research Report U1501 - January 14, 2015

This report analyzes ten categories of utility-sector energy efficiency programs that have achieved high participation among targeted customer markets. Despite issues with the nature and availability of participation data, the study draws on published data sources and interviews with program...

Research Report - June 30, 2015

In 1980, energy efficiency researchers formed the American Council for an Energy-Efficient Economy (ACEEE). As we turn 35 years old this year, we thought it would be useful to look at energy efficiency progress over the past 35 years and to also look at possible and recommended pathways for the...

White Paper - June 30, 2015

Although the relationship between water and energy is a close one, the energy intensity of water and wastewater systems is relatively undocumented. To advance the understanding of the water-energy nexus and bring attention to possible opportunities, the National Association of Water Companies (...

Research Report - June 24, 2015

This report details the wide range of benefits of energy efficiency to the electric utility system, including traditional avoided cost of energy as well as many other economic benefits. These benefits accrue to all utility customers, including those who have not participated in programs. The...

Research Report - June 16, 2015

This report describes the multiple benefits of energy efficiency in multifamily retrofit programs and discusses particular ways of establishing their value so administrators can include them in cost-effectiveness testing.  Multiple benefits are the impacts of energy efficiency improvements...

White Paper - June 10, 2015

This paper is one in a three-part ACEEE series on utility business models for energy efficiency. The two other reports examine state-by-state experience with utility performance incentives and ...

Research Report - June 10, 2015

White Paper - June 02, 2015

The Environmental Protection Agency’s proposed Clean Power Plan establishes state-specific targets for carbon dioxide emissions from existing power plants. This tool is intended to help states document and claim emissions reductions resulting from the adoption of combined heat and power (CHP)....

White Paper - May 27, 2015

The Environmental Protection Agency’s proposed Clean Power Plan establishes state-specific targets for carbon dioxide emissions from existing power plants. This tool is intended to help states document and claim emissions reductions resulting from the adoption of energy efficiency financing...

Regulatory Filing - May 27, 2015

The Tennessee Valley Authority 2015 Draft Integrated Resource Plan takes significant steps towards inclusion of energy efficiency on equal footing to supply side resources. However, there is still opportunity to improve the methodological approach related to the inclusion of energy efficiency as...
