Every year, much of the energy the U.S. consumes is wasted through transmission, heat loss and inefficient technology -- costing American families and businesses money, and leading to increased carbon pollution.

Energy efficiency is one of the easiest and most cost effective ways to combat climate change, clean the air we breathe, improve the competitiveness of our businesses and reduce energy costs for consumers. The Department of Energy is working with universities, businesses and the National Labs to develop new, energy-efficient technologies while boosting the efficiency of current technologies on the market.
