The electrification of homes in the United States began in the late 19th century, with a pivotal moment occurring in 1878 when Thomas Edison installed the first private electric system in his own residence. This sparked a wave of electrification that spread across borders, with the first Canadian private electric system following in 1882. In the early days of electrification, electricity was carried by bare copper wires with minimal insulation, and sockets, switch handles, and fuse blocks were made of wood. Over time, electrical wiring and insulation improved, and by the 1940s, electricians began using metal conduits, enclosing multiple insulated wires in rigid metal tubes. While half of American houses had electricity by 1925, it was mostly in urban areas, and rural electrification lagged. Thanks to the Rural Electrification Act of 1936, 85% of American homes had electricity by 1945, and by 1960, virtually all homes were electrified.

Electric lighting in homes
The history of electric lighting in homes is a fascinating one. Before the advent of gas and electric lighting, the primary source of indoor lighting was usually a fixed fire in the hearth, with candlelight or oil lamps providing additional, but dim, light. Candles were expensive, so home activities were centred around the hearth.
The development of lighting technology on an industrial scale in the late 18th century brought about the first gas lighting. This was initially used in the street and in factories, with home use becoming popular among the middle classes in the 19th century. However, gas lighting had its drawbacks, including choking fumes, smoke, blackened walls, and the risk of explosions.
Electric lighting began to emerge in the mid-19th century, with huge electric arc streetlamps appearing in the 1870s, providing intense illumination. These arc lamps were far too powerful for homes, so inventors began working on a way to produce a less powerful electric light for indoor use. This led to the development of the incandescent lamp bulb, with early experimenters like Joseph Swan and Thomas Edison trialling materials for a durable filament as early as the 1840s.
In 1875, Henry Woodward patented an electric light bulb, and in 1879, Thomas Edison and Joseph Swan patented the carbon-thread incandescent lamp, which lasted 40 hours. In 1882, Thomas Edison's Pearl Street Station introduced large-scale direct current-based indoor incandescent lighting.
In September 1882, a house in Appleton, Wisconsin, became the first American home to be powered by hydroelectricity, using Thomas Edison's direct current (DC) system. However, it wasn't until FDR's Rural Electrification Act of 1936 that electricity became widespread in American homes. By 1945, 85% of American homes had electricity, and by 1960, virtually all homes were electrified.
The introduction of electricity transformed everyday life, providing illumination at the flick of a switch. Over time, the demand for electricity grew with the popularity of appliances like vacuum cleaners, refrigerators, and washing machines. Today, modern homes have safety features such as grounded wires and circuit breakers to protect against electrical hazards.

Early electrification
The electrification of American homes has been a gradual process, with significant developments occurring over the course of the late 19th century and early 20th centuries.
In the years before electrification, homes relied on fire in the hearth, candles, and oil or gas lamps for lighting. These traditional methods had drawbacks, including fire risk, soot deposits, and poor indoor air quality.
The earliest days of electrification in American homes can be traced back to the late 19th century. In 1882, a house in Appleton, Wisconsin, became the first American home to be powered by hydroelectricity, using Thomas Edison's direct current (DC) system. This marked the beginning of the ""Battle of the Currents," where Edison's DC was promoted as "safe" compared to the "dangerous" alternating current (AC) championed by George Westinghouse. However, by the early 1890s, AC had emerged as the winner due to its ease of long-distance transmission, allowing for the use of inexpensive hydroelectric power.
From about 1890 to 1910, knob and tube wiring was used for early electrical installations. During this period, hot wires and neutral wires were run separately and insulated using rubberized cloth. As electrification expanded, it brought about significant changes in how communities were constructed. The introduction of electric streetcars enabled people to travel greater distances, leading to the development of suburban layouts. Electrification also made skyscrapers possible through the invention of the electric elevator, allowing buildings to exceed previous height limitations.
In the early 20th century, lighting accounted for most of a home's energy usage, and gas lamps remained common. By 1925, only half of American houses had electrical power. The Rural Electrification Act of 1936, part of President Franklin D. Roosevelt's New Deal legislation, aimed to provide cheap electricity to the masses. As a result, by 1945, 85% of American homes were powered by electricity, and by 1960, virtually all homes had electricity.
The expansion of electrification brought about improvements in wiring and safety measures. From the 1920s to the 1940s, flexible armored cable offered some protection from wire damage. Electricians began using metal conduit in the 1940s, enclosing multiple insulated wires within rigid metal tubes. Grounded wires, introduced after 1965, further enhanced safety by directing stray electrical currents back into the ground.

Rural electrification
The Rural Electrification Act of 1936 (REA) was enacted on May 20, 1936, to provide federal loans for the installation of electrical distribution systems in isolated rural areas across the United States. This was one of many New Deal proposals by President Franklin D. Roosevelt to address high unemployment during the Great Depression.
Prior to the Act, electricity was commonplace in US cities, but largely unavailable in farms, ranches, and other rural areas. By the 1920s, electric power had become an essential part of modern life in cities, with more than half of urban homes having electric lights and appliances. However, rural electrification was not considered economically feasible, and private utility companies were reluctant to invest in the necessary infrastructure due to the low population density in these areas. As a result, by 1932, only about 10% of rural America had access to electricity, and this disparity in access to electricity fueled a growing divide in living standards between city and farm life.
The REA provided loans to electric cooperatives that were repaid over 30 years. These cooperatives were member-owned and purchased power at wholesale prices, distributing it through their own transmission and distribution lines. The Act also provided low-cost federal loans to consumers for wiring houses and purchasing electric appliances. This encouraged electricity consumption and helped bring down electric rates.
The implementation of the REA had a significant impact on the lives of rural Americans. For example, Louisan Mamer, a Home Electrification Specialist, traveled around the country teaching people how to use and maintain electric equipment and appliances, and how to use electricity safely. The REA also improved access to water pumps, electric stoves, and washing machines, drastically improving the quality of life for many rural Americans, especially women.
