U.S. coal consumption decreased 4.0% from the 2017 level to 688.1 MMst. The electric power sector accounted for about 92.6% of the total U.S. coal consumed in 2018.
The term Peak coal is used to refer to the point in time at which coal production and consumption reaches its maximum, after which, it is assumed, production and consumption will decline steadily. The term was originally used in connection with M. King Hubbert's Hubbert peak theory, in which the finite nature of the resource determines a constraint on production.
Vast areas of wildlife habitat, the most biologically diverse forest in North America, have been obliterated. Roughly 2000 miles of streams have been filled or severly degraded by mining waste, all in pursuit of coal. And coal is a lousy way to power a society. From mining to burning to disposing the combustion waste, it's a dirty business.
COAL DEPLETION ALLOWANCE The depletion allowance deduction is one of the more complex mysteries of mineral taxation. This article will explain in detail the rules governing the depletion allowance deduction as applied to coal mining. The prime focus of this article is the coal operator's depletion allowance deduction. However, the
