The term "market transformation" was first coined in 1992 to describe the process which substantially increases the energy efficiency of all new appliances, buildings, vehicles, or other technologies over time. In the subsequent decade, dozens of market transformation initiatives have been operated in the U.S. This paper looks at 28 of the major initiatives, how they have fared in the market, and the lessons each initiative teaches. It concludes with a summary of lessons learned that should be kept in mind when developing and refining market transformation initiatives in the future.
