Why do we mine coal?
Given the environmental and safety issues, why do we still mine coal? In a world where carbon emissions are not taxed, coal is a very inexpensive and efficient way to generate electricity. Coal is also one of the most abundant energy sources in the entire world, and it’s relatively efficient for generating electricity.
How many years of coal do we have left?
Based on U.S. coal production in 2018, of about 0.76 billion short tons, the recoverable coal reserves would last about 332 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.
How was coal used in the past?
The use of coal as an energy source dates back to second and third century Rome, with archeological evidence suggesting it was mined from outcroppings and used as a heating source. By the 1700s coal was widely used because it burned cleaner and hotter than wood charcoal, helping to fuel the Industrial Revolution.
