Since most of the insulation is provided by the surrounding air, overhead power lines are generally the least costly method of power transmission for large quantities of electric energy.
The electrical transmission system combined with power plants, distribution systems, and sub-stations to form what is known as the electrical grid.
The grid meets society's electricity needs, and is what gets the electrical power from its generation to its end use. Since power plants are most often located outside of densely populated areas, the transmission system must be fairly large.
