Electrification is the process of powering by electricity and is
usually associated with changing over from another power source.Broadly speaking, electrification was the build out of the electrical generating
and distribution systems which occurred in the United States, Britain
and other countries from the mid-1880s until around 1950 and is in
progress in rural areas in some developing countries. This included the
change over from line shaft and belt drive using steam engines and water power to electric motors.

In the 1830's Michael Faraday discovered the operating principle of electromagnetic generators. The principle, later called Faraday's law, is that an electromotive force is generated in an electrical conductor that is subjected to a varying magnetic flux, as for example, a wire moving through a magnetic field. His innovations, like the first electromagnetic generator (seen below), offered vast contribution to the fields of electromagnetism and electrochemistry, and kick-started a series of experimentation and invention in electric power.

Faraday disk, the first electric generator. The horseshoe-shaped magnet (A) created a magnetic field through the disk (D).
When the disk was turned, this induced an electric current radially
outward from the center toward the rim. The current flowed out through
the sliding spring contact m, through the external circuit, and back into the center of the disk through the axle. source

Parson's generator lead to a revolution in marine propulsion, and was a predecessor to today's turbo-generators. source | | | | |

By the 1930's, 90% of urban dwellings were powered by electricity, but in rural areas, only 10% had access. Electric power was controlled by private business, and thus much of the rural population either could not afford or were too isolated from urban power lines to get power. In 1935, the Rural Electric Administration (REA) was formed in the hope that government involvement would provie elctricity, and thus improved lifestyles for rural peoples. By 1939 the REA had helped to establish 417 rural electric cooperatives,
which served 288,000 households. The actions of the REA encouraged
private utilities to electrify the countryside as well. By 1939 rural
households with electricity had risen to 25 percent. While the REA undoubtedly had its benefits in rural areas, they were not able to stop the large amounts of families relocating to the cities, or the evolving culture of family farms.
