the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source.
note:s
Considering the strong correlation between copper and electricity use, electrification in its two meanings, bringing electricity to a region or fuel switching, is a strong driver for copper demand. Over the past decades, a ratio of ~ 1,000 tCu/TWh electricity demand has been observed though that correlation may well be spurious.
Historically, electrification was the build-out of the electricity generation and electric power distribution systems that occurred in Britain, the United States, and other now-developed countries from the mid-1880s until around 1950 and is still in progress in rural areas in some developing countries.
