The concept of energy efficiency has moved in and out of favor with the public over the years, but recently has gained renewed broad-based support. The confluence of economic, environmental and geopolitical concerns around reducing America's exposure to disruptions in the supply of energy has moved efficiency to the fore. As a result, along with renewable energy legislation, a number of initiatives are now underway in the U.S. to improve efficiency in a variety of areas, but much more can and should be done.

Improving transmission capacity is also vital to the integration of renewables like wind and solar which are often located far from the loads they must serve. For that reason, the cause of efficiency in the T&D system is in perfect alignment with that of expanding renewable generation. As renewable energy technologies continue to grow in importance, the potential impact of energy efficiency cannot be overstated.
