6 before the time of Jesus.the famous Greek philosopher of the century Tales about his experiments with electricity the first studies amber chopsticks. This method is known as electrification by friction and can lift light objects, and stark. It is very inefficient. 18. century, galvanic batteries could not be invented and electricity became available after this date. Galvanic batteries, Electric batteries formed and stored as chemical energy. Batteries, can adapt to work with a lot in common. However, the amount of energy that can host is limited. Once empty, must be loaded again. Very large power requirements for the transit should continue as the conductor of electrical energy and should be created as.

Usually electrical power electro-mechanical generators with fossil fuels is produced. Is used or generated as a result of nuclear reactions. On the other hand, can be produced by using the kinetic energy of wind or water. Sir Charles Algernon Parsons steam turbine was invented in 1884 by Modern and produces approximately 80 percent of the electric power used in the world today. This kind of generators, generator-produced disk has nothing to do with the principles of Faraday in 1831, but these devices still is based on the principles of electromagnetic information. In the nineteenth century the invention of the transformer, electric power with a higher voltage but lower current is more efficient and has allowed moved. Efficient electrical transmission, built-in power stations can be created. The winners in the economic dimension. When the need arises may be carried to very distant places at the same time.

The increasing importance of wind energy in many countries
Since electrical energy is stored easily in sizes large enough to accommodate international needs, always needs to be produced enough to meet our needs. For this reason, the organizations offering to the public of electricity to be able to make accurate predictions about the accumulation of power stations need to maintain the coordination of

International modernlestik as the economy improves and as the demand for electricity also began to increase. In the first three decades of the twentieth century in the United States each year, the need for electricity increased by 12 percent. This increase the economy in developing countries such as China and India currently deneyimleniy't. Historically, the demand for electricity increase more than the need for other energy. .

Concerns about the production of electricity, caused the increase of interest in renewable energy sources, especially wind power and hydraulic power plants. The debate continues over the environmental impact of electricity production, although it is quite clear than it was the latest situation.
