Louis Armstrong was one of the most influential artists in the history of music. Born in New Orleans, Louisiana, on August 4, 1901, he began playing the cornet at the age of 13. Armstrong perfected the improvised jazz solo as we know it. Before Armstrong, Dixieland was the style of jazz that everyone was playing.
The nation's fleet of over 100 coal plants is responsible for 57 percent of the electricity generated in the U.S., more than any other single electricity fuel source. Coal is typically burned to create steam, which is then piped at high pressure over a turbine, causing it to rotate, producing electricity.
Coal is primarily used to generate electricity and is responsible for 39 percent of the electric power supply in the United States in 2014 (down from half in 2007). The United States produces around 11.5 percent of the worldâs total with Wyoming, West Virginia, Kentucky, Pennsylvania, and Texas leading in production.
