What are disadvantages of coal?
The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
How much coal is left in the world?
There are 1,139,471 tons (short tons, st) of proven coal reserves in the world as of 2016. The world has proven reserves equivalent to 133.1 times its annual consumption. This means it has about 133 years of coal left (at current consumption levels and excluding unproven reserves).
Who first discovered coal?
Coal was one of man’s earliest sources of heat and light. The Chinese were known to have used it more than 3,000 years ago. The first recorded discovery of coal in this country was by French explorers on the Illinois River in 1679, and the earliest recorded commercial mining occurred near Richmond, Virginia, in 1748.
