Before Thomas Edison’s commercial electricity systems, American factories were not powered by electricity. They relied mainly on mechanical power sources, especially during the Industrial Revolution (late 1700s to late 1800s).
The main sources of factory power were:
1. Water power (hydropower) — 1700s to 1800s
The earliest factories were built near rivers because flowing water could turn large water wheels.
- Water wheels powered:
- textile mills
- sawmills
- paper mills
- grain mills
- iron works
Example:
- The textile mills of New England (Massachusetts, Rhode Island, Connecticut) were often located along rivers such as the Merrimack River.
- Water turned mechanical shafts that ran machines through belts and gears.
2. Steam engines — from the early 1800s
Steam became the dominant factory power source in the 19th century.
Factories burned:
- coal
- wood (earlier)
- later petroleum products
to heat water and create steam, which moved pistons and powered machinery.
By the mid-1800s:
- large textile factories
- steel mills
- rail workshops
- shipyards
were increasingly using steam engines.
A typical factory had:
- a large central steam engine
- rotating shafts running through the building
- leather belts connecting the shafts to individual machines
3. Human and animal power
Small workshops and farms also used:
- workers turning cranks
- horses and mules
- treadmills
These were common before large-scale industrialization.
4. Wind power (limited use)
Windmills were used mainly for:
- grain milling
- water pumping
but were not a major industrial power source in the United States.
Timeline of American industrial power
| Period | Main factory power |
|---|---|
| 1700–1820 | Water wheels, human/animal power |
| 1820–1880 | Steam engines + water power |
| 1880–1900 | Steam engines + early electricity |
| After 1900 | Electricity becomes dominant |
What did Edison change?
When Thomas Edison developed practical electric lighting and power distribution systems in the late 1870s and early 1880s, electricity began replacing steam-driven mechanical systems.
His Edison Illuminating Company opened the first commercial central power station at Pearl Street Station in New York City in 1882.
However, factories did not immediately switch to electricity. For several decades they continued using steam engines because:
- electricity was expensive,
- power grids were limited,
- factories already had steam infrastructure.
The major factory transformation came around 1900–1920, when electric motors allowed each machine to have its own motor instead of depending on a central steam shaft.
So, before Edison:
Factories were powered mainly by rivers and coal-fired steam engines.
After Edison and the spread of electric grids:
Factories moved toward electric motors and modern industrial production.
Britain began using coal extensively in the Industrial Revolution, but coal use started much earlier.
Early use of coal in Britain
- Roman period (around AD 100–400): The Romans used coal in parts of Britain, mainly for heating and metalworking.
- Middle Ages (1200s–1500s): Coal mining expanded, especially in Northumberland, Durham, Yorkshire, and Scotland, as forests became depleted and wood became more expensive.
- 1600s: Coal became a major fuel in London and other growing cities for heating homes, brewing, brick-making, and metal industries.
Coal and the Industrial Revolution
The major transformation happened in the 1700s:
- 1709: Abraham Darby I successfully used coke (a coal-derived fuel) to smelt iron at Coalbrookdale, reducing dependence on charcoal.
- 1760s–1800s: Coal became the foundation of Britain’s Industrial Revolution, powering:
- steam engines
- textile factories
- iron and steel production
- railways
- ships
- 1776: James Watt improved the steam engine, making coal-fired steam power far more efficient for factories and mines.
Peak coal era
By the 1800s, Britain was the world’s leading coal producer:
- Coal powered factories, railways, and ships.
- Major industrial cities such as Manchester, Birmingham, and Sheffield grew around coal-powered industries.
- By the late 19th century, coal supplied the majority of Britain’s energy.
Simple timeline
| Period | Role of coal in Britain |
|---|---|
| AD 100–400 | Romans use coal locally |
| 1200–1500 | Coal mining expands |
| 1600s | Coal replaces wood for many urban uses |
| 1700s | Coal drives the Industrial Revolution |
| 1800s | Britain becomes a global coal superpower |
| 1900s | Coal remains dominant but gradually declines |
In summary: Britain started using coal over 1,800 years ago, but it became the country’s main industrial energy source from about 1700–1800, making it the fuel that powered the British Empire and the Industrial Revolution.
No. Hydroelectric power is older than wind-generated electricity, although wind power as a mechanical energy source is older than hydroelectricity.
The difference is between using wind/water to do mechanical work and generating electricity.
1. Wind power (mechanical use) — very old
Humans used windmills thousands of years ago:
- Around 1,000 years ago (and possibly earlier): Windmills were used in Persia and later Europe for:
- grinding grain
- pumping water
- other mechanical tasks
However, these windmills did not produce electricity.
2. Hydropower (mechanical use) — also very old
Water power is even older:
- Ancient Greece (around 3rd century BC): Water wheels were used for grinding grain.
- Later, medieval Europe used water wheels to power:
- mills
- sawmills
- metalworking
3. Electricity generation from water and wind
Hydroelectricity came first:
- 1878: The world’s first known hydroelectric power system was demonstrated at Cragside, England, using a water turbine to generate electricity.
- 1882: The first commercial hydroelectric plant in the United States began operation in Appleton, Wisconsin.
- 1895: Large-scale hydropower began at Niagara Falls.
Wind electricity came later:
- 1887–1888: The first known wind turbine generating electricity was built by James Blyth in Scotland.
- 1888: Charles F. Brush built one of the first large wind turbines for electricity generation in Ohio.
Timeline comparison
| Technology | First major use |
|---|---|
| Water wheels (mechanical power) | ~300 BC |
| Windmills (mechanical power) | ~700–1000 AD |
| Hydroelectric electricity | 1878–1882 |
| Wind-generated electricity | 1887–1888 |
Conclusion:
- If talking about mechanical power, water power is older than windmills.
- If talking about electricity generation, hydropower came first by about 5–10 years.
- Hydropower became a major industrial electricity source much earlier because rivers provided continuous, predictable energy compared with wind.
