Energy Star (1992)
The Environmental Protection Agency launched a voluntary label for energy-efficient computers, then expanded it to appliances, buildings, and homes. The label became the accepted mark of efficiency in the marketplace.
Manufacturers competed to earn the label, and efficiency became a selling point.
Energy Star is now nearly universal in appliances and commercial buildings, with consumer recognition above 90%.
Shows how a voluntary, incentive-based program can turn efficiency into a market norm, the same path NYSERDA's competition is trying to create for low-carbon housing.
