Coal is the largest source of electricity supply in the world with 41% of the global power coming from the burning of coal.The Pros of Coal have made the growth of Thermal Power Plants accelerate in developing countries like China and India.This has made Coal Stocks run up by more than 150% in 2010 and another 30% in 2010.However Coal is also the greatest contributor to Greenhouse Gas Emissions.Coal is also responsible for thousands of deaths directly and indirectly due to Coal Mining and Coal Combustion which leads to waste products like Mercury,Arsenic etc which are extremely toxic to human health.To solve the twin problems of cheap energy and global warming, a number of technologies have been been proposed which would reduce the harmful effects of Coal Combustion.

Despite a number of Clean Coal Technologies being developed and employed,carbon emissions from Coal Ming and Use can only be partly reduced and will not make a major impact on the problem of Climate Change.Clean Coal Technology is not a Green Solution to the Disadvantages of Coal.Saying that implementing Clean Coal Technology will result in Climate Change Mitigation is Greenwashing.That said these technologies need to be implemented till the world is ready to move away from its addiction to cheap energy provided by Coal even though it has a deleterious long term affect.

Coal is the Biggest Contributor to Global Warming generating billions of tons of carbon dioxide during combustion.Coal is one of the most abundant fossil fuels available on earth and it is expected that Coal will last another 200 years.The mass usage of Coal and its deleterious effect on the environment makes Coal a controversial choice of Energy.Coal is responsible for 25% of Human Energy Consumption and is the largest producer of Electricity in the world.
Coal causes Human Deaths in the Thousands each year directly through Mining Deaths and Indirectly through Human Diseases like Lung Cancer,Mercury and Arsenic Poisoning.The costs of Coal are artificially low because these costs are passed onto society and not explicity added onto the cost of coal powered electricity or coal products like Steel and Cement.Reducing Coal Usage gradually is a big necessity but given the growing hunger for energy by India and China and lack of a Climate Agreement that looks unlikely in the near future
