What are 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.
Does coal have a future?
The current administration favors coal, but that policy may not continue in future administrations. Displacing coal-fired power generation is a very cost-effective way to reduce U.S. energy-related greenhouse gas emissions, and thus could be targeted by a future administration more concerned about climate.
How many years of coal is left?
Based on U.S. coal production in 2019, of about 0.706 billion short tons, the recoverable coal reserves would last about 357 years, and recoverable reserves at producing mines would last about 20 years. The actual number of years that those reserves will last depends on changes in production and reserves estimates.
