How is Electricity Generated, Transmitted and Distributed?

Electricity is generated or produced by turning or rotation of turbines. These turbines can be rotated by any means – coal, steam, nuclear energy, renewable energy such as solar energy etc. In most power plants, turbines are rotated by the pressure of steam. This steam is created by boiling water using burning coal in large boilers.
