External costs of coal - SourceWatch

{{#badges: CoalSwarm}} In economics, an external cost, or externality, is a negative effect of an economic activity on a third party. When coal is mined and used to generate power, external costs include the impacts of water pollution, toxic coal waste, air pollution, and the long-term damage to ecosystems and human health.

Energy profile (chemistry) - Wikipedia

For a chemical reaction or process an energy profile (or reaction coordinate diagram) is a theoretical representation of a single energetic pathway, along the reaction coordinate, as the reactants are transformed into products. Reaction coordinate diagrams are derived from the corresponding potential energy surface (PES), which are used in computational chemistry to model chemical reactions by ...

coal – Sankey Diagrams

The other coal Sankey diagram is for U.S. coal imports and exports in 2010. Here the unit is in 1,000s of short tons, hence the two must not be directly compared. Also, the inset of the yellow arrow for domestic production in comparison to U.S. import/export is not to scale with the other flows shown on the flow map.

Generating Electricity from Coal - Duke Energy

Duke Energy has been using coal to produce electricity in the Carolinas since 1911. Those first coal-fired plants (in Greensboro, N.C., and Greenville, S.C.) only supplemented the company's use of hydroelectricity. In the 1920s, the growing demand for electricity began to outstrip the availability of hydroelectric generation.

Coal Mining - Coalwood, West ia

Coal Mining. Types of Coal Mines. There are four main types of coal mines: shaft mine, slope mine, drift mine, and surface (open-cast) mine. The mine at Coalwood was a shaft mine; the coal was brought up in an elevator from 600 to 800 feet underground. The University of Kentucky has an interesting diagram showing each of the four types of mining.
