Parker estimates that by eliminating wall outlets for charging the cellphone, a single person a can save nearly 0.144kW a day, or 52.560kW a year. Push to charge could also be implemented in other button-tap devices like laptops, keyboards, or other computing devices. Furthermore, it could potentially reduce the amount of wattage pulled from fossil fuels, wall outlets, and other non-green resources to a great extent.
