[13] main article WebApr 11, 2024 · An MIT study shows that if U.S. nuclear power plants are retired, the burning of coal, oil, and natural gas to fill the energy gap could cause more than 5,000 premature deaths. Nearly 20 percent of today’s electricity in the United States comes from nuclear power. The U.S. has the largest nuclear fleet in the world, with 92 reactors scattered ...
WebAlong with being clean and long burning, anthracite is used because it has a very high energy density —33 MJ /kg—the highest of any type of coal. [3] When burned, anthracite can reach very high temperatures, making this fuel exceptional at heating up quickly, releasing immense amounts of energy and burning very hot. [4] For Further Reading
