The UK government has signalled its plan for a green industrial revolution, and a target to increase the number of homes on heat networks from 2% to 18% by 2050. Geothermal energy from mines, combined with heat pump technology, could provide a sustainable energy source that is both local and low cost. With an estimated one-quarter of the UK's ...

The constant leaching of heavy metals from coal mining and coal plants leads to bioaccumulation in plants and animals, creating the danger of toxicity. Heavy metal toxicity can result in damaged or reduced mental and central nervous function, lower energy levels, and damage to blood composition, lungs, kidneys, liver, and other vital organs.

Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground. Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.
