If you live in California, charging your electronics will soon be getting a little cheaper. Last week, the California Energy Commission approved new rules governing efficiency for battery chargers, including those used for phones, laptops, and even vehicles like forklifts or golf carts. Since the Commission estimates that only about 36 percent of electricity used by chargers actually makes it into batteries, companies will have until next year to provide the same performance with improved efficiency in consumer electronics, either by reducing the amount of power needed for a full charge or by no longer drawing electricity once the battery is full. Currently, many chargers continue to use power even after a device is done charging or has been unplugged, a phenomenon known as "vampire" or "no-load" power.
