In 2007, Congress passed and the President signed into law the Energy Independence and Security Act that set new minimum efficiency standards for general service light bulbs used in both residential and commercial buildings. Similarly in 2009, the US Department of Energy passed new standards that will eliminate most of the least efficient types of linear fluorescent lamps typically used in commercial buildings. The impact of these standards – including their impact on electric ratepayer funded efficiency program portfolios – has been the subject of considerable debate. This November 1, 2011 webinar presentation, created by Gabe Arnold and Glenn Reed, is designed to inform regulators, advocates and others on the best current thinking regarding the implications of the lighting efficiency standards.
