Motion (current) is not required; for example, if there is a voltage difference in combination with charged particles, such as static electricity or a charged capacitor, the moving electrical energy is typically converted to another form of energy (e.g., thermal, motion, sound, light, radio waves, etc.).
The fundamental principle of electricity generation was discovered during the 1820s and early 1830s by the British scientist Michael Faraday.
His basic method is still used today: electric current is generated by the movement of a loop of wire, or disc of copper between the poles of a magnet.
[2] Electricity is most often generated at a power station by electromechanical generators, primarily driven by heat engines fueled by chemical combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind.
There are many other technologies that can be and are used to generate electricity such as solar photovoltaics and geothermal power.
