How does coal mining affect the environment?
As previously mentioned, coal mining and processing is responsible for contributing a significant amount of pollution to the environment. In addition, extraction techniques, such as mountaintop removal, change the surrounding landscape. In this extraction process, seams of coal are removed from the mountainside by using explosives to remove the top of the mountain, making the coal below easier to access. The excess land and debris, that was once the top of the mountain, is generally pushed into the valley below, a practice known as valley fill. This permanently alters the topography of the land, leading to obstructed waterways and increased flooding.

What are the external costs of coal?
A 2001 EU-funded study known as ExternE, or Externalities of Energy, over the decade from 1995 to 2005 found that the cost of producing electricity from coal would double over its present value, if external costs were taken into account. These external costs include damage to the environment and to human health from airborne particulate matter, nitrogen oxides, chromium VI and arsenic emissions produced by coal. It was estimated that external, downstream, fossil fuel costs amount up to 1–2% of the EU's entire Gross Domestic Product (GDP), with coal being the main fossil fuel accountable, and this was before the external cost of global warming from these sources was even included. The study found that environmental and health costs of coal alone were €60/ MWh, with the energy sources of the lowest external costs being nuclear power €1.9/MWh, and wind power at €0.90/MWh.
