The history of electricity is a long and fascinating one. While the concept of electricity has been known for millennia, it was not until the 19th century that it began to be used to power homes and communities. The first true battery was invented by Italian scientist Alessandro Volta in 1800, and English scientist Michael Faraday invented the electric motor in 1821. Thomas Edison, an American inventor, is often credited with pioneering the world's first electric power distribution system, which marked the beginning of widespread electrification. By the early 20th century, electricity was still mainly used for lighting, but by the 1950s, the demand for electricity had soared with the popularity of appliances like vacuum cleaners, refrigerators, and washing machines.

What You'll Learn
Early electricity milestones
The ancient Greeks first observed static electricity, but it was not until the 17th century that the English scientist William Gilbert made a careful study of electricity and magnetism, distinguishing between the lodestone effect and static electricity produced by rubbing amber. He coined the term "electricus" to refer to the property of attracting small objects after being rubbed. This gave rise to the English words "electric" and "electricity", which first appeared in print in 1646.
In the early 1700s, English scientist Francis Hauksbee made a glass ball that glowed when rubbed, demonstrating electrical attraction and repulsion. This discovery would eventually lead to neon lighting. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles.
In 1800, Alessandro Volta invented the first battery, or voltaic pile, made from alternating layers of zinc and copper. This provided scientists with a more reliable source of electrical energy than previous machines. In 1819-1820, Hans Christian Ørsted and André-Marie Ampère discovered electromagnetism, the unity of electric and magnetic phenomena. Michael Faraday invented the electric motor in 1821, and in 1827 Georg Ohm mathematically analysed the electrical circuit.
In 1832, Frenchman Hippolyte Pixii invented the first rudimentary dynamo. By the 1860s, the construction of the first transcontinental and transatlantic telegraph systems allowed electricity to enable communications across the globe in minutes. In 1870, Belgian inventor Zenobe Gramme devised a dynamo that produced a steady direct current (DC) source well-suited to powering motors, generating enthusiasm about electricity's potential to light and power the world. In 1882, a house in Appleton, Wisconsin became the first American home to be powered by hydroelectricity, using Thomas Edison's DC system.

The first battery
Following Galvani's findings, Volta performed a series of experiments on electrochemical phenomena during the 1790s. He believed that observed electrical phenomena were caused by two different metals joined by a moist intermediary. He verified this hypothesis through experiments and published the results in 1791.
The invention of the voltaic pile was significant as it led to new discoveries and experiments. For example, it allowed for the first electrolysis of water by English surgeon Anthony Carlisle and English chemist William Nicholson. It also led Michael Faraday to derive the quantitative laws of electrochemistry, which established the exact relationship between the quantity of electrode material and the amount of electric power desired. These laws formed the basis of modern battery technology.
The voltaic pile also played a role in the naming of batteries. Colonial American inventor Benjamin Franklin is credited with possibly being the first to use the term "electrical battery", drawing from the military term for weapons functioning together. Franklin created an early capacitor by linking "Leyden jars", which were glass jars filled with water (or another conducting material) and lined with metal foil.
While Volta is credited with creating the first true battery, there is evidence of earlier battery-like technology. The "Baghdad Battery", a ceramic pot battery discovered in the remains of a village on the outskirts of Baghdad, is over 2,000 years old. It is believed to have been used for metallic plating rather than generating electricity, with a voltage of about 1.5-2 volts.

Electric power distribution
The history of electricity generation and its distribution is a fascinating one. For millennia, electricity was little more than an intellectual curiosity. The English scientist William Gilbert wrote 'De Magnete' in 1600, in which he studied electricity and magnetism, distinguishing between the lodestone effect and static electricity produced by rubbing amber. The words "electric" and "electricity" first appeared in print in 1646.
However, it was not until the 19th century that electricity generation and distribution began to be explored in earnest. The electrical telegraph, demonstrated commercially in 1837, was one of the earliest applications of electricity, enabling global communication in minutes. The first rudimentary dynamo, which generates electric currents, is credited to Frenchman Hippolyte Pixii in 1832. This was improved upon over the next few decades, and by the 1870s, dynamos were being used to power arc lighting in cities around the world.
The mid-1880s saw a breakthrough with the development of functional transformers, allowing alternating current (AC) to be "stepped up" to a higher voltage for transmission and then reduced for the end user. This made it possible to supply electricity over long distances, and large AC generating plants could supply whole cities and regions. The first power-distribution systems were used to supply lighting in European and US cities.
Urban distribution is mainly underground, while rural distribution is mostly above ground with utility poles. The final circuit in an urban system is typically shorter than in a rural system, which may be over 91 metres.

Electric lighting
The history of electric lighting is a long and fascinating one, spanning centuries and involving numerous inventors and scientists across the globe. The development of electric lighting can be traced back to the early 19th century, with the first constant electric light demonstrated in 1835. However, it was not until the mid-19th century that electric lighting began to be used in practice, first in street lighting and factories, and later in homes.
One of the earliest forms of electric lighting was the arc lamp, which was demonstrated by English chemist Humphry Davy in 1806, with the first persistent electric arc developed by Vasily Vladimirovich Petrov in 1802. Arc lamps were used experimentally in Paris in 1841 and became a common form of street lighting in the 1870s, providing intense illumination. The first public use of arc lighting in the US was in 1878 in a department store in Philadelphia. By the early 1900s, arc lamps were largely replaced by incandescent light bulbs.
The incandescent light bulb was a significant development in electric lighting. While Thomas Edison is often credited with its invention, he was preceded by British inventors demonstrating the electric arc lamp and English chemist Humphry Davy, who invented the carbon arc lamp around 1805. In 1879, Englishman Joseph Wilson Swan produced the first viable incandescent bulb, and Edison and Swan later merged their efforts, forming the Edison and Swan Electric Light Company. Edison's practical design and focus on distributing electricity from centralized power stations contributed to the widespread adoption of incandescent bulbs.
The incandescent bulb underwent further improvements, such as the introduction of the tungsten filament in 1904, which increased bulb longevity and brightness. By the 1910s, neon lighting and fluorescent lamps were being demonstrated, and fluorescent lighting became commercially successful after World War II. The first practical LED was introduced in 1962, and LED technology experienced a boom in the 1990s.
The adoption of electric lighting in homes was a gradual process. Gas lighting became popular among the middle classes in the 19th century, but it had drawbacks, including fumes and the risk of explosions. Electric lighting in homes became a viable alternative, offering brighter interiors and giving rise to decorative lampshades, switches, and bulbs. By the 1930s, new homes in urban areas of Britain were being lit by electricity, and the number of wired homes increased significantly over time.

Electric cars
The history of electricity is a fascinating one, with many pioneers contributing to its development over the centuries. One of the earliest known applications of electricity was in the form of the electrical telegraph, demonstrated commercially in 1837 by Cooke and Wheatstone.
Now, let's delve into the history of electric cars, a significant innovation that has built upon the foundation laid by these pioneers.
The concept of electric cars is not new, and they have been around in some form for over a century. The first electric cars appeared long before their gas-powered counterparts, with innovators in Hungary, the Netherlands, and the United States creating some of the first small-scale electric cars in the early 19th century. Scottish inventor Robert Anderson developed a crude electric carriage between 1832 and 1839. Around the same time, in 1835, Professor Sibrandus Stratingh of Groningen, the Netherlands, and his German assistant, Christopher Becker, created a small-scale electric car powered by non-rechargeable primary cells.
In the United States, Thomas Davenport, a Vermont blacksmith, built a similar vehicle that operated on a short, circular, electrified track in 1834. The first electric locomotive was also developed during this period in 1837 by Scottish chemist Robert Davidson.
The late 1800s saw the emergence of more practical, commercially available electric vehicles. The first battery rail car was introduced in 1887, and French inventor Gustave Trouvé tested what was likely the first human-carrying electric vehicle with its own power source in 1881.
By 1900, electric cars were at their peak, accounting for around a third of all vehicles on the road. However, in the early 20th century, their popularity declined due to the high cost, low top speed, and limited range compared to internal combustion engine vehicles. Despite this, electric vehicles continued to find use in public transport and for loading and freight equipment.
The turn of the 21st century brought renewed interest in electric cars due to rising gasoline prices and environmental concerns. The Toyota Prius, introduced in Japan in 1997 and worldwide in 2000, became the world's first mass-produced hybrid electric vehicle. Nissan Leaf, introduced in 2011, became the world's top-selling highway-capable electric car, with over 200,000 units sold as of December 2015. Tesla, a Silicon Valley startup founded in 2003, also gained traction with its luxury electric sports cars, and by August 2020, the Tesla Model 3 became the world's all-time best-selling plug-in electric passenger car.
Today, electric vehicles are experiencing a resurgence, with a growing demand for hybrid, plug-in hybrid, and all-electric cars. As of 2020, cumulative sales of light-duty plug-in electric cars reached 10 million units globally. This trend is expected to continue, with electric vehicle sales projected to grow worldwide.
