What is "Clean Coal"?

I read, What the heck is “Clean Coal”?, by Jacob Leibenluft. It was about what exactly the “clean coal” that the presidential candidates are always talking about. Clean coal is not really changing the coal, but more of a way to catch the carbon dioxide that it created from the burning. The united states has previously cut down coal emissions by 70 percent in 1990, but coal is still the worst substance when it comes to the amount of emissions that it causes. The general idea that I got after reading the article is that this technology is quite expensive, but if used, it would drastically cut down coal emissions. What we, as a country, should really be focused on though is helping other, more coal dependent, countries use this technology, because coal is not our only source for power and we have the “cleaner” coal in the world. Although it was never said in the article, I think one country that should definitely have this technology is China, because of the terrible emissions in their air. The voice of the article is more of an informative formal voice. There are a few parts that are a bit relaxed, but the article is all about the facts and what would be a smart thing to do when thinking about this issue. The audience that the article is really trying to get is the more educated and those of voting age. There is a lot of reference to the candidates throwing around this term and what they are actually saying, so I think it is safe to assume that they are trying to inform voters.
