## Electric light arrives, but only a few streets at a time

In the late 1800s, most Americans still lit their homes with gas or oil lamps and candles. Horses pulled much of the traffic through town. Electricity was beginning to appear, but for most people it was something they might see on a city street rather than use at home.

Things were starting to change. In 1882, Thomas Edison opened [the first commercial power station in the United States built to supply incandescent electric light](https://www.nps.gov/edis/learn/kidsyouth/timeline-of-edison-and-his-inventions.htm?utm%5Fsource=chatgpt.com). His Pearl Street station sent power through underground cables to nearby homes and businesses. But “nearby” was the problem: customers had to be within about half a mile of the station. If electricity was going to spread much further, someone needed to work out how to deliver it across a city and beyond.

Other companies were putting up lights too, including the bright lamps that lit city streets. Their electricity came from their own generators, often travelling along wires strung overhead. Electric light was beginning to make an impression. So were the wires needed to bring it to people.

## Edison vs Westinghouse: two ways to power a city

Edison had built something people could see working. His power station supplied nearby customers with [direct current (DC)](https://www.energycrewhq.com/ac-dc-more-than-a-band-what-actually-powers-your-home/?utm%5Fsource=chatgpt.com), and his companies knew how to build more stations like it. The problem was how to reach everyone else. At the voltage Edison’s system used, serving the next neighbourhood meant building another station, with its own generators and cables. Expanding across a city meant repeating that expense again and again.

[George Westinghouse](https://guides.loc.gov/this-month-in-business-history/october/george-westinghouse?utm%5Fsource=chatgpt.com), an inventor who had made his fortune in railways, saw an opportunity. His company backed alternating current (AC), which could be sent at a higher voltage and brought down again near customers. [Transformers made that possible](https://americanhistory.si.edu/collections/object/nmah%5F705959?utm%5Fsource=chatgpt.com), offering a less costly way to serve places farther from a station. Westinghouse also bought the rights to Nikola Tesla’s AC motor, giving businesses a way to use that electricity to run machinery as well as lights.

The promise was enormous. One system was already lighting buildings; the other offered a way to take electricity much farther. But as more wires appeared above the streets, the question of how to reach people became tangled with another one: how safely could it be done?

In October 1889, [John Feeks](https://erenow.org/common/edison-and-the-electric-chair/17.php?utm%5Fsource=chatgpt.com), a lineman working above a New York street, touched a telegraph wire that had come into contact with an AC electric-lighting wire. He was killed in front of the people below. The rivalry had begun before Feeks died, but his death gave the argument over safety a face. Edison had already warned about high-voltage AC. Now he had a tragedy he could point to, while Westinghouse had to defend the system he wanted people to trust.

## How safety became a weapon in the Current War

The danger was real. Poorly managed high-voltage wires could kill people, whatever the commercial claims made for the electricity they carried. Edison believed those wires had no place over public streets. He also had a considerable business interest in persuading customers and city officials that Westinghouse’s approach was the wrong one. Both things can be true.

The campaign was already taking a grim turn before Feeks died. [Animals were electrocuted in experiments and demonstrations](https://edison.rutgers.edu/life-of-edison/essaying-edison/essay/the-current-wars?utm%5Fsource=chatgpt.com) intended to show what AC could do, and New York State had adopted electricity as a method of execution. A Westinghouse generator was obtained for the electric chair despite Westinghouse’s refusal to supply one. When William Kemmler became the first person executed in the chair in 1890, Westinghouse’s company was caught up in an association he had fought to avoid.

Westinghouse could argue that AC would bring electricity to many more places. Edison could ask what price people might pay if it was installed badly. Newspapers carried the argument, but neither man could settle it there. Westinghouse needed the public to see his system doing something useful, safely and on a scale Edison’s early stations could not match.

## The 1893 Chicago World’s Fair puts AC on show

That opportunity came at the 1893 Chicago World’s Fair. The contract to light the fair was a contest between Westinghouse and General Electric, the company formed after Edison’s electrical business merged with another rival in 1892\. [General Electric reportedly bid $554,000; Westinghouse bid $399,000](https://teslasciencecenter.org/pivotalmoments/columbian-expositions/?utm%5Fsource=chatgpt.com). The organisers chose Westinghouse. Edison’s name remained central to the public story, though he was no longer running the company competing for the job.

When the fair opened, its buildings and grounds glowed with electric light. Visitors did not need to understand a transformer or Tesla’s motor to see the attraction. Here was a vast public space lit by the system they had been told to fear. For Westinghouse, it was the sort of demonstration no newspaper argument could quite equal.

The fair showed that AC could handle a spectacular job. The next challenge was less theatrical and more important: could it deliver electricity from where it was made to a city some distance away?

## Niagara Falls proves AC can go the distance

![An engineer stands beside the large generators inside the Niagara Falls power station, where AC electricity was produced](https://storage.ghost.io/c/f6/c8/f6c8c43e-7a52-4694-bbc3-80def3debbe5/content/images/2026/10/1895-Niagara-Power-House-Generator-Hall.png)

At Niagara Falls, a new power station was being built to turn the force of the water into electricity. Westinghouse supplied generators, using a system shaped by Tesla’s work and built by a much larger team of engineers. [The first generator began operating in 1895](https://americanhistory.si.edu/collections/object/nmah%5F1281694?utm%5Fsource=chatgpt.com). The following year, electricity from Niagara reached Buffalo, about 20 miles away.

Chicago had shown people what AC could do. Niagara showed the electricity industry how far it could go. Power made at the falls could serve customers in another city, rather than requiring a new station in every neighbourhood. That was the advantage Westinghouse had been arguing for all along. AC did not win the entire country overnight, but Niagara made its case much harder to dismiss.

## What happened to Edison and Westinghouse?

Winning the argument over distance did not mean Westinghouse kept control of the business he had built. The [financial panic of 1907 cost him control of his companies](https://guides.loc.gov/this-month-in-business-history/october/george-westinghouse?utm%5Fsource=chatgpt.com). He continued to invent and died in 1914\. Edison had moved away from the lighting business years earlier, while Tesla carried on pursuing electrical ideas long after the commercial battle that made him famous.

There was one last twist. In 1911, [Westinghouse received the Edison Medal](https://guides.loc.gov/this-month-in-business-history/october/george-westinghouse?utm%5Fsource=chatgpt.com) for his contribution to alternating current. The honour bore the name of the man who had spent years warning people against it.

## Why DC still matters in a world built on AC

![	A modern home with rooftop solar panels and battery storage, showing how DC generation works alongside the AC electricity network.](https://storage.ghost.io/c/f6/c8/f6c8c43e-7a52-4694-bbc3-80def3debbe5/content/images/2026/10/Quiet-Solar-Home-at-Dusk-8.png)

AC became the usual way to deliver electricity across networks, but DC never disappeared. [Solar panels produce DC and home batteries store it](https://www.energy.gov/cmei/systems/articles/solar-plus-storage-101?utm%5Fsource=chatgpt.com), often right where that energy will be used. Your home may draw AC from the grid in the evening, then use energy made on its own roof the next day. The two currents now work together in places Edison and Westinghouse could scarcely have imagined.
