The 1920s saw a rapid increase in the use of electricity, with electric power becoming an essential part of modern life. By 1929, nearly 68% of American homes were electrified, but there was a stark divide between urban and rural areas. While more than half of urban homes had electric lights and appliances, very few farm families had access to electricity. This disparity was due in part to the remote locations of farms, which made it costly for utility companies to connect them to the grid. However, experiments in the 1920s, such as the Red Wing experiment, demonstrated the transformative potential of electricity for farms, with increased productivity and improved health and happiness for farm families.

What You'll Learn
By 1929, nearly 68% of US homes had electricity
The 1920s saw a rapid increase in the use of primary energy, particularly electricity. This was driven by advances in technology, such as Bell Telephone Laboratories' mechanism for recording sound electrically and Westinghouse's de-ion circuit breaker. The electric industry in the US had begun with the 37 MW Tesla-Westinghouse Niagara hydroelectric plant in 1896, and hydropower continued to dominate new capacity additions until the 1930s.
During the 1920s, electric power became firmly embedded in the American way of life. In addition to lighting, electricity was increasingly used to power a range of appliances, including washing machines, irons, vacuum cleaners, toasters, and clocks. By 1935, the adoption of electric irons was nearly universal, and about half of American households had acquired various electric appliances.
The expansion of electrical service required the construction of thousands of miles of high-voltage transmission lines, which made it possible to send power to distant customers and tie together different service areas. This also allowed for smoothing out peaks in demand and sharing power during emergencies. By 1937, the miles of transmission lines above 70,000 volts in the US had increased to more than 35,000 miles from about 3,200 miles in 1914.
The Rural Electrification Administration (REA), formed in 1935, provided subsidised loans to newly established cooperatively owned utilities. This helped to double the number of farms receiving electric service and construct more rural distribution lines than private companies had in the previous 50 years. Economists have found that large-scale infrastructure investments, such as those made by the REA, tend to increase economic growth and reduce poverty.

Urban-rural divide in electrification
By the 1920s, electric power had become an essential part of modern life in the United States. However, there was a significant urban-rural divide in electrification, with most electrified homes located in cities. This disparity was due to several factors, including the higher costs of providing electricity to rural areas and the sparse population in these regions, which made it challenging for utilities to recoup their upfront investments.
By the early 1920s, more than half of all urban homes in the US were electrified, with access to electric lights and a range of electrical appliances. Electric power brought conveniences and efficiencies, improving the lives of city dwellers. Streets and homes were brightly illuminated, and modern appliances like electric stoves and heaters were now accessible.
In contrast, less than 10% of farm families had electricity during this time. By 1930, while nine in 10 urban and nonfarm rural homes had electricity, only about one in 10 farms did. This disparity was not due to a lack of interest from farmers; in 1923, a study in Red Wing, Minnesota, found that farms with access to electricity and electric appliances reported significantly higher productivity and happiness. However, the cost of building transmission lines to remote farms was prohibitively high, often exceeding $2,000 per mile.
The stock market crash of 1929 and the subsequent Great Depression highlighted the increasing poverty and challenges faced by rural America. It also shifted the conservative climate of power supply in the country, making it socially acceptable for the government to intervene and provide electricity to rural areas. President Herbert Hoover, who served during this time, favoured electrification and wanted to improve the lives of all Americans, including farmers. However, he took a hands-off approach, believing that private enterprise should accomplish this objective.
It wasn't until the Rural Electrification Administration (REA) was established in 1935 that significant progress was made in electrifying rural America. The REA provided subsidised loans for connecting farms to the electric grid, and by the mid-1950s, almost every farm in the country had electricity. The REA's efforts demonstrated that access to electricity improved agricultural outcomes and reduced the negative impact of the Great Depression in counties that received electricity.

Electric appliances in homes
By 1929, more than half of all urban homes had electric lights, and many of those homes had electric appliances. However, relatively few farm families had electricity. Electric appliances in homes were becoming increasingly common in the 1920s, with the development of vacuum sweepers, toasters, irons, refrigerators, and ranges. The 1920s saw great strides in both technical and decorative designs, with toasters, for example, being encased in sculptural deco shells. The market for household appliances, however, plummeted during the Great Depression following the 1929 stock market crash.
The Red Seal Plan, introduced in 1924, promoted adequate wiring for convenient electric service. Homes wired according to the plan were placarded with a Red Seal, and the homeowner received a certificate as evidence. Motor repair work grew tremendously in the 1920s, especially in larger cities.
The Tennessee Valley region, one of the most impoverished regions of the United States in the 1920s, had the potential to produce huge amounts of hydroelectric power. However, it was not until 1931 that the U.S. Army Corps of Engineers issued a report highlighting the potential for cheap electric power, flood control, and improved navigation and health conditions through coordinated development of the river system.
During the Great Depression, the Public Works Administration (PWA) provided funding for electrification projects, creating tens of thousands of jobs. The Rural Electrification Administration (REA), created in 1935, provided subsidized loans for connecting farms to the electric grid, improving agricultural outcomes and reducing poverty.

Electric power generation and transmission
By 1929, electricity had become an essential part of modern life. More than half of all urban homes had electric lights, and many of those homes had electric appliances. However, relatively few farm families had electricity. Electric power transmission, or the movement of electricity from its source to distant locations, had been in development since the late 19th century. The widespread transmission of electric power faced two major obstacles: the need for specialized generators with separate lines for devices with different voltage requirements, and the proximity of generators to their loads (within a mile for low-voltage devices).
The solution to these problems lay in efficiently transforming voltages from a single universal power line. However, early electricity was primarily direct current, which was challenging to adjust for long-distance transmission or sharing a common line with multiple device types. High voltage transmission offered a promising solution, as it allowed for the transfer of the same amount of power with reduced current, enabling longer-distance transmission.
The 1920s witnessed significant advancements in electric power generation and transmission. The decade saw the introduction of improved power transmission, better distribution, enhanced motors, new controls, and trans-Atlantic telephone service. The electrical industry benefited from innovations such as Bell Telephone Laboratories' mechanism for recording sound electrically, Westinghouse's de-ion circuit breaker, and Martin Hochstadter's three-core power cable, among others.
The California Electric Company in San Francisco, established in 1879, was a pioneering example of a utility selling electricity from a central plant to multiple customers via transmission lines. This business model, akin to the gaslight industry, marked the beginning of electricity delivery through flexible "pipes". Charles Brush's New York arc lamp systems, Edison's incandescent lights, and Siemens-Sprague streetcars were among the early electricity consumers, each requiring their own specialized lines due to varying voltage needs.
In 1929, Editor S. B. Williams highlighted the progress made in small circuit breakers for residential purposes, aiming to address issues with overfused circuits. The Red Seal Plan, introduced in 1924, promoted adequate wiring for convenient electric service and provided certification to homeowners ensuring their homes were wired according to the plan. The 1920s also saw the emergence of salary surveys within the electrical industry, revealing insights into the earnings and business structures of electrical contractors.

Electrification and economic growth
By the 1920s, electricity had become an essential part of modern life, with more than half of urban homes in the US having electric lights and appliances. However, electrification varied across regions, with rural areas lagging behind. For example, in the 1930s, fewer than 10% of farms in the US had access to electricity, and many farm families still relied on kerosene lamps for lighting.
The Tennessee Valley region, which was one of the most impoverished regions in the US during the 1920s, presented an opportunity for electrification. Its rivers held the potential to produce significant amounts of hydroelectric power. In 1931, the US Army Corps of Engineers issued a report highlighting that cheap electric power, flood control, and improved navigation and health conditions could be achieved through coordinated development of the river system.
Electrification projects, such as the Rural Electrification Administration (REA) in the US, provided subsidized loans to connect farms to the electric grid. Counties that gained electricity through the REA experienced smaller declines in agricultural productivity, land values, and increased retail activity compared to similar counties without access to electricity.
Additionally, large-scale infrastructure investments, including electrification, have been found to contribute to economic growth and poverty reduction. Studies have shown that electrification can stimulate agricultural production and improve economic outcomes in rural areas. However, there has been limited research on the impact of smaller, more targeted electrification projects.
