I remember growing up in a small town in Western Colorado where the snow was black. Anyone with any type of lung problems had to move out of the area. Small children had to be kept indoors when it got bad. It was from the local Sugar Beet Factory. They were told that they had to go to Natural Gas to stay in business so they tore out all the coal feeders from the burners (they melted them down) and installed Natural Gas Jets. Then Natural Gas went sky high for a few years and they said they couldn't stay in business. In order to keep using Coal, they had to install the proper scrubbers that made Coal unprofitable. The Factory closed down and it devistated the community. It was the main source of income and labor. Today, the town has about the same population and the air is fit to breath. England and China have yet to figure that out and you can see what it's doing both places.
The only way that coal is viable is if the proper scrubbers are used.
I will say this is a good post, Where I grew up it was the same. Coal has to be burned in an efficient way to be viable, But the BTU return per dollar is better than any fuel. The waste also has to be handled properly. The coal from Powder river absin is some of the cleanest burning in the continental US with proper mixture it can be used with the eastern mined coal to achieve almost the same BTU and much less output of sulfur Dioxides too. The process of pulverizing the coal to minute particles and high pressure introduction and extreme burn temperatures made the burn much cleaner too. As stated the oshit-ma administration regulated the coal industry out, Probably so he could set up the "Green energy initiative" to funnel billions of taxpayer dollars to his comrades, and the dnc. slime ass gore took 100 million dollars (NET 98 good return on 2 mil) out of JUST one of the companies that got a billion or so when it went belly up as it was designed to do by the dnc and the government thieves in office. Don't you figure That paid the bill for all of the next elections and put lots in the pockets of the players.
