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?
Many decisions are made on the basis of the payback period: the time it will take through savings to equal the capital cost of an investment. Acceptable payback times depend upon the business or philosophy one has. (For some industries, a payback period is as small as two years.) Suppose you wish to install the extra insulation. If energy cost $1.00 per million joules and the insulation was $4.00 per square meter, then calculate the simple payback time. Take the average for the 120 day heating season to be 15.0C.
A 400 kg satellite is in a circular orbit at an altitude of 425 km above the Earth's surface.

At a certain location, the solar power per unit area reaching Earth’s surface is 200 W/m2, averaged over a 24-hour day.
