Find it! Helpful tools for cutting phantom loads from cell phonesWant to ensure that you're not wasting energy unnecessarily? Buy an ENERGY STAR charger, or consider a solar charger, or a device that includes audio alerts that remind you to unplug the charger when your battery is full.
Unplugging your charger helps you go green becauseA typical US household uses between five to ten adapters/chargers, and each year, more than one billion new adapters are shipped worldwide.
Only five percent of the total power consumed by a charger is used to juice up a cell phone, smartphone, or PDA. Even while charging, 10 to 16 times more energy is often drawn from the outlet than can be retrieved by the batteries, which means the efficiency for many cell phones is as low as six to 20 percent. The US Environmental Protection Agency (EPA) estimates that if every phone sold in the US in 2007 used ENERGY STAR qualified chargers, which are 40 percent more efficient than standard chargers, the energy saved would prevent over one million tons of greenhouse gas emissions, which is the equivalent emissions of more than 200,000 cars, and could light 760,000 homes per year. Additional national annual savings include 4.5 billion kWh of electricity use, three million tons of carbon dioxide from power plant emissions, and $380 million dollars on the end users' electricity bill.
