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.
Waste heat. Much of the heat produced from burning coal is wasted. A typical coal power plant uses only 33-35 percent of the coal's heat to produce electricity. The majority of the heat is released into the atmosphere or absorbed by the cooling water.aste created by a typical coal plant includes more than 125,000 tons of ash and 193,000 tons of sludge from the smokestack scrubber each year. Nationally, at least 42 percent of coal combustion waste ponds and landfills are unlined.
