California OKs Energy Efficiency Rules for Battery-Charged Devices
January 18, 2012
The California Energy Commission on January 12 approved a first-in-the-nation energy efficiency standard that will reduce wasted energy by battery chargers used with cell phones, laptop computers, power tools, and other devices. The proposed standards can save nearly 2,200 gigawatt hours (GWh) each year, enough energy to power nearly 350,000 homes.
Because nearly two-thirds of the 8,000 GWh of electricity consumed in California by battery charger systems (or battery chargers) is wasted by inefficiency, the Energy Commission proposed appliance efficiency standards requiring battery chargers to consume less energy while providing the same performance. Consumer chargers used in cell phones, personal care devices, and power tools will be required to comply with the new standards by February 1, 2013. Industrial charger compliance (e.g. forklifts) is required by January 1, 2014. Compliance for small commercial chargers (such as walkie-talkies and portable barcode scanners) is required by January 1, 2017. See the California Energy Commission press release.
