This article provides information on the following six methods of producing electric power.[1]
Friction: Energy produced by rubbing two material together.
Heat: Energy produced by heating the junction where two unlike metals are joined.
Light: Energy produced by light being absorbed by photoelectric cells, or solar power.
Chemical: Energy produced by chemical reaction in a voltaic cell, such as an electric battery.
Pressure: Energy produced by compressing or decompressing specific crystals.
Magnetism: Energy produced in a conductor that cuts or is cut by magnetic lines of force.[2]
