Research Report - January 06, 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...

This report surveys transportation-sector strategies that use information and communications technologies (ICT) and have the potential to save energy. These include car and bike sharing, real-time transit information, in-vehicle ICT applications, vehicle-to-vehicle (V2V) communications, and...

Research Report - November 12, 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...

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...

Research Report - August 14, 2014

In this report we focus on the development and role of energy efficiency potential studies. The primary objective of our report is to better understand the nuts and bolts of these studies and how their various methodological approaches and assumptions influence energy efficiency potential...

Smart manufacturing is the use of information and communications technology to integrate all aspects of manufacturing, from the device level to the supply chain level, for the purpose of achieving superior control and productivity. A more efficient manufacturing processes is a more energy-...

Research Report - July 17, 2014

In this second edition of the International Energy Efficiency Scorecard, we analyze the world’s 16 largest economies, comprising more than 81% of global gross domestic product and about 71% of global electricity consumption. We looked at 31 metrics, divided roughly in half between...
