The us needs coal so if we found a way to burn it cleanly great! Coal is the cheapest energy source and plants can easily ramp up production unlike natural gas which is always at a max, wind and solar (we cannot control weather) and all other forms of energy besides coal.
Because of the volatility that exists with energy from other countries,"clean coal" would definitely be an option that the United States should utilize.With the technology that is available today,"clean coal" should be an option that could be used without harming the environment to the extent that it can't be reversed.
Clean coal is an oxymoron. All fossil fuels contribute to pollution and global warming. The only solution is to develop an energy source that is actually clean and renewable. Coal is a dying technology that will only lead to more problems. Now is the time to think of the future.
