A kilowatt-hour (kWh) is a unit of measure equal to one thousand watts of electricity being used in one hour. Power companies use this measurement to determine your home energy bill. Consider using a bike for power: It takes 6 minutes pedalling at 24-26 volts consistently to produce just 1/10 (0.1) of a kWh. An average home uses about 25 kWh a day. How long would someone have to pedal at 24-26 Volts to power an average home?
