NY: Efficiency standards for appliances such as ceiling fan and light kits; commercial washing machines; commercial refrigerators, freezers, and icemakers; torchiere lighting fixtures; and other commercial and household items became law on July 29, 2005. New York estimates that the standards will save consumers up to 2,096 gigawatt hours of electricity a year - enough energy to power 350,000 homes - and up to $284 million savings, while reducing carbon dioxide emissions by 870,000 metric tons.
