This article that highlights the biggest coal-fired power plants in the United States, along with their mega-tonnage of carbon dioxide emissions:

• Carbon Dioxide Emissions From Power Plants Rated Worldwide

Here is the list:

• The Scherer plant in Juliet, GA — 25.3 million tons
• The Miller plant in Quinton, AL — 20.6 million tons
• The Bowen plant in Cartersville, GA — 20.5 million tons
• The Gibson plant in Owensville, IN — 20.4 million tons
• The W.A. Parish plant in Thompsons, TX — 20 million tons
• The Navajo plant in Page, AZ — 19.9 million tons
• The Martin Lake plant in Tatum, TX — 19.8 million tons
• The Cumberland plant in Cumberland City, TN — 19.6 million tons
• The Gavin plant in Cheshire, OH — 18.7 million tons
• The Sherburne County plant in Becker, MN — 17.9 million tons
• The Bruce Mansfield plant in Shippingport, PA — 17.4 million tons
• The Rockport plant in Rockport, IN — 16.6 million tons

That is 236 megatons of carbon dioxide emissions in these 12 power plants. The article states:

Globally, power generation emits nearly 10 billion tons of CO₂ per year. The U.S., with over 8,000 power plants out of the more than 50,000 worldwide, accounts for about 25 percent of that total or 2.8 billion tons. CARMA shows that the U.S.’s biggest CO₂ emitter is Southern Co. with annual emissions of 172 million tons, followed by American Electric Power Company Inc., Duke Energy Corp., and AES Corp.

Since the article was written in 2007, you might think that all of these would have been decommissioned in the last 13 years and replaced with something cleaner. You would be wrong. The good news is that two of them have closed, but the other 10 are still open, generating megatons of carbon dioxide every year. Each one has its own Wikipedia page:
