A study by DOE 's Oak Ridge National Lab found that radioactive emissions from coal combustion are greater than those from nuclear power production. 10. A 500 megawatt coalfired electrical plant burns 1,430,000 tons of coal, uses billion gallons of water and 146,000 tons of limestone a year.
Most of the coal deposits are about 300 million years old. The recent coal deposits of the Tertiary Age are generally of inferior quality. Depending upon the percentage of carbon present, the coal can be grouped in four types, such as peat, lignite, bituminous and anthracite.
Bituminous coal, on the other hand, is the type of coal most commonly used in America to produce electricity. The chemical makeup and creation process is what makes these types of coal so distinct from each other. In general, anthracite is harder than bituminous coal. This is .
The five largest coal users – China, USA, India, Russia and Japan – account for 76% of total global coal use. Different types of coal have different uses.
West ia's coal markets have historically been divided into northern and southern regions, as they produce different types of coal that depend on different types of customer demand.

The increase in coal consumption across the globe has predominantly been due to demand for greater electricity generation in China, India and other nonOECD countries which have seen total power generation double since 2000. Well over half of this new power generation has come from coal. China alone now uses as much coal as the rest of the world.
Canada's coal industry has been able to maintain its production levels despite the country's decline in consumption. But now a decrease in global demand is hurting business.
Another impact of coal mining and extraction on regional water quality is the runoffcalled Acid Mine Drainage (AMD)from active and retired coal mines, and is the most common nonpoint source pollutant in the Mid Atlantic region.
