What Are Electrical Generators?

Electric generators are devices which create electricity from mechanical energy, normally by an electromagnetic induction method. Electromagnetic induction is done by forcibly moving a piece of wire around a stationary bar which then provides an electrical field, either via a permanent magnet or an electromagnet. This creates a current within the rotor which is used to power machinery etc. Some sources of mechanical energy are steam engines, water through a turbine, internal combustion engine, a wind turbine, solar energy, compressed air. The electrical generator is the creation of today’s electrical generation. If electrical generators cease to operate, then most of the worlds economy would grind to a halt.

The electrical generator was invented by Anyos Jedlik who was Hungarian, somewhere between 1827 and 1830. Anyos created the generator which was a simple dynamo, six years before Warner von Siemens and Charles Wheatstone, whose names are linked with this device’s invention. Although it was invented in 1830, it was not until 1882 that Nikola Tesla’s work on rotating magnetic fields would make it possible for generators to be used for industrial use. The electrical revolution in the United States happened in the 1890s, helping to start the Second Industrial Revolution.

Today, there are several different variations, ranging from 3 to 6 watts which can power everything from bicycle lights to hydroelectric generators in China, which provide 22.5 gigawatt’s. The worldwide production of electricity is around 20,000 terawatts, with approximately 66% created via thermal burning of fossil fuels, 16% via hydro, 15% from nuclear, and 2% from renewable energy like wind or solar power. For environmental reasons, worldwide efforts are being taken to expand electrical production to more Eco friendly ones. Many homeowners now are taking full advantage of the likes of solar panels installed on their roofs to not only reduce their energy bills but to be more Eco friendly also.
