The Life Cycle of Coal - Pearson Fuels Pearson Fuels

Nov 05, 2018· The Life Cycle of Coal. As one of the most important fossil fuels around, coal takes around 300 million years to come about during a process known as coalification. In fact, there are many different varieties of coal that can be repurposed for a range of different uses depending where in its life cycle it is when it is excavated.

Mining Coal, Mounting Costs: The life cycle consequences ...

But, from extraction to combustion, coal, oil and natural gas have multiple health, environmental and economic impacts that are proving costly for society. We estimate that the life cycle impacts of coal, and the waste stream generated, are costing the U.S. public a third to over one-half a trillion dollars annually. Coal carries a heavy burden.
