What is an electricity generator? 

    An electricity generator is a device for converting mechanical energy into electrical energy. The process is based on the relationship between magnetism and electricity. When a wire or any other electrically conductive material moves across a magnetic field, an electric current occurs in the wire. The large generators used by the electric utility industry have a stationary conductor. When the magnet rotates inside the stationary conductor it induces a small electric current in each section of wire as it passes. Each section of wire constitutes a small, separate elastic conductor. All the small currents of individual sections add up to one current of considerable size. This current is what is used for electric power.

          The electric generator was first invented by the Hungarian inventor and engineer Anyos Jedlik between 1827 and 1830. Jedlik invented the generator, a simple dynamo, at least six years before Werner von Siemens in Germany and Charles Wheatstone in Britain, whose names are usually associated with the device’s invention. Though the electrical generator was invented around 1830, it wouldn’t be until Nikola Tesla’s pioneering work  on rotating magnetic fields around 1882 that generators would become suitable for industrial use. Today exist electrical generators of all imaginable sizes, from 3 – 6 watt generators to power bicycle lights to the hydroelectric generators in the Three Gorges Dam (дамба «Три ущелини») in China, which provide 22, 5 gig watts of power when they were fully installed in 2012. The current worldwide production of electricity is about 20.000 terawatt – hours, with about 66% generated through nuclear, and 2% through renewable such as wind or solar power converting.
