Ships, trains, houses, manufacturing and power plants—each have used, or currently uses, coal as its main fuel source.  Coal has long been one of the world’s top energy sources, acting as the base of nearly 30 percent of the energy created across the globe and almost 40 percent of global electricity production.  However, after Murray Energy Corporation became the eighth coal company on October 29th, 2019 to declare bankruptcy in the past 14 months, there appears to be a significant downturn occurring within the industry.  Murray Energy is the largest privately held coal company in the United States and joined seven other companies within the industry, including Cloud Peak Energy and Westmoreland Mining, in filing for bankruptcy.
