Electric lighting came into wide use at the end of the last century with the development of the electric lamp by Thomas Edison. Then the transformer was invented, the first electric lines and networks were set up, dynamos and induction motors were designed.
Since the beginning of the 20-th century the successful development of electricity has begun throughout the industrial world. The consumption of electricity has doubled every ten years.
Today consumption of electricity per capita is an indicator of the state of development and economic health of a nation.
Electricity has replaced other sources of energy as it has been realized that it offers improved service and reduced cost.
One of the greatest advantages of electricity is that it is clean, easily regulated and generates no by-products. Applications of electricity now cover all fields of human activity. Truly electricity provides mankind with the energy of the future.
