In 1879, Thomas Edison focused on inventing a practical light bulb, one that would last very long time before burning out. The problem was finding a strong material for the filament, the small wire inside the bulb that conducts electricity. Finally, Edison used ordinary cotton thread that had been soaked in carbon. These light bulbs worked, but they were battery powered and expensive.

The next challenge was developing an electrical system with practical source of energy to power these new lights. Edison wanted a way to make electricity both practical and inexpensive. He designed and built the first electric power plant that was able to produce electricity and carry it to people’s homes.

Edison’s pearl street power station started up its generator on September 4, 1882, in New York City. About 85 customers in lower Manhattan received enough power to light 5,000 lamps. His customers paid a lot for their electricity, though in today’s dollars, the electricity cost 5$ per kilowatt- hour. Today, electricity costs about nine cents per kilowatt-hour for residential customers, less for industry.
