Before electricity was utilized for this purpose, other natural sources such as coal and water were used. This is rather an unconventional way of fueling up factories because the said energy sources are not readily available for industrial use. With the discovery of the incandescent bulb by Thomas Edison, a series of other discoveries and inventions gave way for instant sources of energy. Electric utilities were ushered in during the late ? Although these utilities had a low transmission range and limited power, wide residential use became possible.
These utilities were further developed by George Westinghouse that made it possible to supply both residential homes and power-hungry industries the energy that they needed to perform daily business tasks.
