NEW YORK, March 26 (Reuters) - As U.S. power demand rises, utilities are planning to build more than 150 plants fired by coal, a plentiful but dirty fuel.
The United States is the world's top emitter of carbon dioxide, the main gas scientists link to global warming, but does not regulate the emissions.
Utilities are coming under greater pressure from some green organizations to capture C02 with expensive equipment and bury it underground. But the technology, which is not yet commercially available, could boost power bills by 20 percent, according to scientists that advise the United Nations, as well as a recent report from the Massachusetts Institute of Technology.
Below is a list of power plants that are being built. If completed they will add about 7.6 Gigawatts of capacity to the grid. Also listed are plants that have completed permitting and are expected to begin construction soon.
Many of plants will burn plentiful coal from Wyoming's Powder River Basin as Appalachian output in the East begins to decline.
The remaining plants of the 150 being planned are mostly in the permitting process, and it is not certain how many of them will be built.
