What You'll Learn
The evolution of electricity generation
In the 1700s, scientists such as Francis Hauksbee and Benjamin Franklin conducted early experiments with electricity, leading to the discovery of the link between lightning and electricity, as well as the invention of the glass friction generator. These developments laid the foundation for further advancements in the field.
The 1800s saw the emergence of modern renewable energy generation, with hydropower becoming the first commercial electricity generation source. Michigan’s Grand Rapids Electric Light and Power Co. generated DC electricity using hydropower in 1880, marking a significant milestone in the transition to renewable energy. By the late 1800s, there were numerous hydroelectric plants in operation, powering homes and industries.
The 1900s witnessed a broader range of energy sources being adopted, including oil, gas, and nuclear energy. The first commercial nuclear power plant in the US came online in 1957, and the industry experienced rapid growth in the 1960s and 1970s. However, this expansion was short-lived due to various challenges, including slower electricity demand growth and regulatory requirements.
In recent years, there has been a growing trend towards renewable energy sources, such as wind, solar, and hydroelectric power. The development of photovoltaic technology and the declining cost of solar power have made it a major driver of the renewable energy transition. Additionally, advancements in computer chip technology and the emergence of smart devices have further transformed the way we generate and use electricity.
As we move forward, it is expected that renewable energy sources will continue to play an increasingly important role in electricity generation, with improvements in technology and a growing demand for sustainable practices.

The electrification of the home
The electrification of homes has come a long way since the earliest days, when electricity was carried by bare copper wires with minimal cotton insulation, and sockets, switch handles, and fuse blocks were made of wood. The first American home to be powered by electricity was in Appleton, Wisconsin, in 1882, using hydroelectricity and Thomas Edison's direct current (DC) system. However, it took several decades for electric lighting to be adopted in homes outside of the very wealthy. By the late 1920s, about half of U.S. households reported using electricity.
Early residential electrical systems had limited capacity, requiring household members to use appliances one at a time to avoid overloading the system. Knob-and-tube wiring, which was standard from 1890 to 1910, involved running hot wires and neutral wires separately, with porcelain knobs and tubes protecting the wires through the framing. This wiring method had safety hazards and degraded over time due to the use of rubberized cloth insulation. From the 1920s to the 1940s, flexible armored cable offered improved protection from wire damage, and electricians began using metal conduit to enclose multiple insulated wires.
The introduction of electricity into homes brought about significant changes in daily life. Electric lighting replaced gas lights and candles, altering the daily rhythm of life. Electric stoves, which gained popularity in the 1950s, reduced the risk of fire compared to wood-burning stoves. The use of domestic appliances, such as washing machines, refrigerators, and vacuum cleaners, revolutionized household work, particularly for women, as professions like maids and domestic servants declined.
Today, modern electrical systems have evolved to include NM cables with copper wire conductors or PVC. Safety features like GFCI outlets provide individual grounding capability, and AFCI (arc-fault circuit interrupters) help prevent fires. As homes and appliances become "smarter," the demand for electricity and new innovations continues to grow. Renewable energy sources, such as wind, solar, and hydroelectric power, are increasingly being adopted, and direct current (DC) is making a comeback due to its efficiency in transmitting large volumes of electricity over long distances.

The shift from fossil fuels to renewable energy sources
Renewable energy sources, such as wind, solar, and hydropower, emit little to no greenhouse gases and are readily available. They are also, in most cases, cheaper than coal, oil, or gas. The cost of electricity from solar power has decreased significantly, falling by 85% between 2010 and 2020. The prices of onshore and offshore wind energy have also dropped, by 56% and 48% respectively. This makes renewable energy more attractive, especially to low- and middle-income countries, where most of the additional demand for new electricity will come from.
The transition to renewable energy offers several benefits beyond addressing climate change. It helps reduce air pollution, which caused $2.9 trillion in health and economic costs in 2018, and improves public health. It also contributes to sustainable economic growth, job creation, and greater equality, particularly for vulnerable communities. Additionally, renewable energy sources are available in all countries, reducing import dependency and providing energy security.
However, the transition is not without its challenges. It requires a multifaceted approach that considers infrastructure, technology, policy, and equity. There is also resistance from some countries, particularly those that have not been major contributors to greenhouse gas emissions and are still developing, as they believe it may hinder their economic growth. To accelerate the transition, significant international coordination is needed to expand and diversify manufacturing capacity and ensure widespread access to renewable energy components and raw materials. Additionally, domestic policy frameworks must be reformed to streamline and fast-track renewable energy projects and catalyze private sector investments.

The development of electrical appliances
The first documentation of electricity dates back to 500 BC when Thales of Miletus discovered static electricity by rubbing fur on amber. However, it wasn't until the 1600s that English physician and physicist William Gilbert published the first theories about electricity in his book, "De Magnete". In the early 1700s, English scientist Francis Hauksbee experimented with electrical attraction and repulsion, creating a glowing glass ball bright enough to read by, which eventually led to neon lighting.
The 1800s witnessed significant advancements, including Alessandro Volta's invention of the battery and Humphry Davy's creation of the first effective "arc lamp". The world's first central DC hydroelectric station powered a paper mill in Appleton, Wisconsin, in 1882. This marked the beginning of domestic electrification, and by the 1960s, most basic functions in Swedish homes were electrified, including washing machines, refrigerators, cookers, vacuum cleaners, and irons. Electric stoves, which gained popularity in the 1950s, reduced the risk of fire and made homes safer.
The 20th century brought breakthroughs with wind, nuclear, and tidal power, and the development of solar panels and electric cars. Today, renewable energy is the fastest-growing source of electricity, and solar power is now the least expensive source of electricity. As technology advances, a transition to renewable power sources as our primary producers of electricity is expected.
The evolution of electrical appliances has had a profound impact on society. It led to the disappearance of certain professions, such as maids and domestic servants, and empowered women to work outside the home. Additionally, organisations like Föreningen för Elektricitetens Rationella Användning (FERA) in Sweden played a crucial role in spreading information about the benefits of electricity use, particularly targeting women through courses in electric cooking.
