Research Report - 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 - January 07, 2015

Businesses that implement energy efficiency improvements often enjoy other benefits besides utility bill savings. However previous efforts to measure multiple benefits have been sporadic and far from rigorous. Still, evidence suggests that including non-energy impacts can reduce the payback time...

Research Report - December 18, 2014

A zero net energy (ZNE) building is a home or commercial building that on average produces as much energy as it uses, achieved through energy efficiency and renewable technologies.  Building energy codes can help us transition to ZNE construction for new residential and commercial buildings by...

Research Report - November 13, 2014

The U.S. economy shows signs of weakening. Among the reasons for less vigorous economic activity is the inefficient use of resources—and especially the inefficient use of energy. New information and communication technologies (ICT) make possible dramatically reduced costs and higher levels of...

White Paper - November 05, 2014

This paper shows a range of energy intensities for water and wastewater services and in residential hot and cold water. We draw from existing data to develop national estimates of energy savings associated with water savings, including energy used in water conveyance, water heating, and water...

Research Report - October 22, 2014

For the past eight years, the ACEEE State Energy Efficiency Scorecard has measured the progress of state policies and programs that save energy while also benefiting the environment and promoting economic growth. Using data vetted by state energy officials, we rank states in six...

Research Report - October 01, 2014

Combined heat and power (CHP) technologies, also known as cogeneration, generate electricity and useful thermal energy in a single integrated system. CHP projects can offer substantial economic, environmental, and energy benefits to their owners, including reduced overall energy costs, improved...
