For climate change activists and those hoping for an energy future dominated by renewables or even less-polluting natural gas, the death of coal cannot come quickly enough. But with coal still the dominant form of cheap electricity throughout the world, it is unlikely the bogeyman of climate change will disappear anytime soon.
That's because the price of coal, compared to other fuels, is just too good to refuse. Just look at China, where the country's double-digit economic growth has largely been fueled by coal, which fulfills 60 percent of its energy mix.
According to a chart [14] showing the levelized cost of energy -- the price at which electricity must be generated from a source to break even -- coal is the second-cheapest form of energy behind hydropower, at $40 per megawatt hour.

Every now and then a valve opens up in the atmosphere allowing impurities to escape into black space.This is an entirely naturally occurring phenomenon that acts like a release valve when our environment has reached it's maximum storage capacity.No planet atmosphere is designed for or capable of amassing pollutants beyond a certain level.Science will soon "discover" this amazing fact.When they do,act surprised.
