Buying a hand crank or solar charger for your mobile devices helps you go green because
- Only 5 percent of the power consumed by standard wall chargers is actually used to charge a cell phone.
- Each year, the earth receives 6,000 times the amount of energy from the sun that people actually consume.
Cell phones charging through a wall outlet are highly inefficient as 10 to 16 times more energy is often drawn from the outlet than can be retrieved by the batteries. If everyone in the US unplugged their charger or used a more energy-efficient or renewably-powered charger, we could save 4.5 billion kWh of electricity use, 3 million tons of carbon dioxide from power plant emissions, and $380 million in end user electricity usage per year.
