In 1752, Benjamin Franklin conducted his famous kite experiment, which expedited the process of understanding electricity. Franklin's work, along with that of other scientists in the 18th and 19th centuries, laid the foundation for the development of electrical technologies that we now take for granted.
In the late 1800s, hydropower became the first modern renewable energy generation source. In 1880, Michigan's Grand Rapids Electric Light and Power Co. generated DC electricity using hydropower, lighting 16 arc street lamps. By 1886, there were 40 to 50 hydroelectric plants operating in the U.S.
The invention of the incandescent light bulb in the 1870s marked another significant milestone in the history of electricity. Thomas Edison is credited with perfecting the light bulb, and lighting became one of the first publicly available applications of electrical power.
The War of the Currents marked the beginning of the modern age of electricity, with new technologies being introduced across America and the world. The demand for electricity led to the establishment of large-scale power generation and high-voltage transmission lines. Coal-powered steam turbines were commonly used in early power plants, and coal remained the primary source of electric power in the U.S. for many years.
Today, electricity is an integral part of our lives, with residential electrical services continuing to evolve and renewable energy sources gaining traction.

The War of the Currents marked the beginning of the modern age of electricity
The War of the Currents was a pivotal moment in the history of electricity, marking the beginning of the modern age of electrical power. This period of intense competition and innovation in the late 19th century laid the foundation for the widespread adoption of electricity as a convenient and versatile energy source.
The war of the currents refers to the rivalry between two competing electric power transmission systems: direct current (DC) and alternating current (AC). Thomas Edison, a renowned inventor, championed the direct-current system, which he had developed to power his groundbreaking incandescent light bulbs. Edison's system supplied electricity to high-resistance incandescent lights, but it had a significant drawback—it could only deliver current to locations within a mile of the power plant.
On the other hand, George Westinghouse and Nikola Tesla promoted the alternating-current system. This system had numerous advantages, including the ability to transmit power over longer distances from large central generating stations. Westinghouse opened the first alternating current plant in Buffalo, New York, and later received a contract to construct AC generators for a hydroelectric power plant at Niagara Falls, solidifying AC's dominance.
The competition between these two systems was fierce, and Edison resorted to propaganda campaigns to discredit AC, claiming it was dangerous. He publicly electrocuted animals using AC and even recommended its use for executions in the electric chair. Despite Edison's efforts, the benefits of the alternating current system were undeniable, and it ultimately became the standard method of transmitting electricity.
The war of the currents came to a close with financial mergers. The Edison company, along with its lighting patents, merged with Thomson-Houston, holders of AC patents, creating a powerhouse that controlled a significant portion of the US electrical business. This merger marked the end of the bitter dispute and the beginning of a unified effort to bring electricity to homes and businesses across America.

The first practical incandescent lightbulb was invented in the 1870s
The history of electricity is a long and fascinating one, with humans beginning to harness its power as early as the 18th century. However, one of the most significant developments in the history of electricity came in the 1870s with the invention of the first practical incandescent lightbulb. This invention was the result of decades of work by scientists and inventors from around the world and marked a turning point in how we use energy, changing the design of buildings, increasing the length of the average workday, and even jumpstarting new businesses.
The man behind this revolutionary invention was Thomas Alva Edison, an American inventor who would go on to transform life in the late 19th century with his various creations. Edison's genius lay in his ability to improve on existing technologies and make them more practical and accessible to the general public. In the case of the incandescent lightbulb, he focused on improving the filament, testing various materials before finally returning to a carbon filament.
By October 1879, Edison and his team at Menlo Park had produced a light bulb with a carbonized filament of uncoated cotton thread that could last for 14.5 hours. This was a significant improvement on earlier incandescent lamps, which had extremely short lifespans and were too expensive or energy-intensive to be practical for widespread use. Edison's lightbulb, on the other hand, burned steadily for hours and could be powered by an electric generator he designed, making it a truly practical lighting solution.
On December 31, 1879, Edison publicly demonstrated his incandescent lightbulb for the first time, lighting up a street in Menlo Park, New Jersey. The event was so highly anticipated that the Pennsylvania Railroad Company ran special trains to accommodate the public's enthusiasm. This demonstration showcased not just the lightbulb but also Edison's complete electrical distribution system, which included dynamos to generate power, wires and fuses, and switches to control the lighting.

The first coal-fired steam generators provided low-pressure steam for steam engines
Electricity has been around for centuries, with the ancient Greeks observing static electricity. However, humans began harnessing it in the 18th century, with the process expedited by Benjamin Franklin's famous kite experiment in 1752. Since the early 20th century, coal, petroleum, and natural gas have been the primary sources of electrical production.
Coal-fired steam generators played a crucial role in the evolution of electricity generation. The first coal-fired steam generators provided low-pressure steam for steam engines, marking a significant advancement in power generation. The steam engine, first recorded by Heron of Alexandria in 1st-century Roman Egypt, underwent various improvements and experiments over the centuries. In the 17th century, Thomas Savery developed a steam pump in England, and in 1679, Denis Papin created a working model of the steam digester.
In 1712, Thomas Newcomen's atmospheric engine became the first commercially successful steam engine, utilizing the piston and cylinder principle. Newcomen's engine revolutionized coal mining by efficiently pumping water out of coal mines. By 1735, over 100 of these engines were installed across England, and their impact extended beyond pumping water. The Newcomen engine's ability to power pumps at different levels throughout the mine and eliminate the need for high-pressure steam made it a versatile tool.
John Smeaton further enhanced the Newcomen engine by improving the seals, almost tripling its efficiency. He also introduced the use of wheels instead of beams for power transfer, making the engines more compact. The Corliss steam engine, patented in 1849, built upon these advancements with improved speed control and efficiency, making it suitable for a wide range of industrial applications.
The development of the steam engine continued to play a pivotal role in the evolution of electricity generation. During the Industrial Revolution, steam engines began to replace water and wind power, eventually becoming the dominant source of power in the late 19th century. The invention of the incandescent light bulb in the 1870s marked a significant milestone, as lighting became one of the first publicly available applications of electrical power.
The evolution of coal-fired steam generators and steam engines laid the foundation for further advancements in electricity generation, leading to the widespread use of electrical power in homes and industries.

Hydropower was the first commercial electricity generation source
Electricity hasn't always been available at the flick of a switch. Humans have been harnessing the power of water for thousands of years, but hydropower was one of the first sources of commercial electricity generation in the late 19th century. Hydropower, or hydroelectric power, is electricity generated from water power.
The ancient Greeks first observed static electricity, but it was in the 18th century that humans began to harness electricity, with Benjamin Franklin's famous kite experiment in 1752. Hydraulic power provided the energy source needed for the start of the Industrial Revolution in the late 18th century. Richard Arkwright used hydropower as an energy source when he set up Cromford Mill in England’s Derwent Valley in 1771 to spin cotton and create one of the world’s first factory systems.
In 1827, French engineer Benoit developed the first version of the Fourneyron reaction turbine, producing around 6 horsepower. In 1849, British–American engineer James Francis developed the first modern water turbine – the Francis turbine – which remains the most widely used water turbine in the world today. In the 1870s, American Inventor Lester Allan Pelton invented the Pelton wheel, an impulse water turbine patented in 1880.
Hydropower technology spread around the globe by the turn of the century, with Germany producing the first three-phase hydroelectric system in 1891, and Australia launching the first publicly-owned plant in the Southern Hemisphere in 1895. In 1895, the world’s largest hydroelectric development of the time, the Edward Dean Adams Power Plant, was created at Niagara Falls. By 1900, hundreds of small hydropower plants were in operation as the emerging technology spread worldwide. The 20th century witnessed rapid innovations and changes in hydropower facility design. Policies enacted by U.S. President Franklin Roosevelt, including the New Deal in the 1930s, supported the construction of several multipurpose projects such as the Hoover and Grand Coulee dams, with hydropower accounting for 40% of the country’s electricity generation by 1940.
Hydropower has continued to grow as a source of electricity generation, with global installed hydropower electrical capacity reaching almost 1,400 GW in 2021, the highest among all renewable energy technologies. Hydropower supplied 15% of the world's electricity in 2023, more than all other renewable sources combined and also more than nuclear power. Hydropower is expected to remain the world’s largest source of renewable electricity for years to come, with significant untapped hydropower potential, particularly in Africa and Asia.
