The invention of light bulb by Thomas A. Edison in 1879 created a demand for a cheap, readily available fuel with which to generate large amounts of electric power. Coal seemed to fit the bill, and it fueled the earliest power stations (which were set up at the end of the nineteenth century by Edison himself). As more power plants were constructed throughout the country, the reliance on coal increased.

In 1620, the settlers, or pilgrims, sailed to America on the Mayflower seeking a place where they could have freedom of worship.
