The power plants they are building today are far cleaner and more efficient than the ones being retired in the U.S., Mr. Clemente said.
"For a vast multitude of the human race, the world is a dark place," said Frank Clemente, a retired Pennsylvania State University professor. "Over 1.2 billion people lack any electricity and another 2 billion or more have inadequate access to power. A key goal of the Copenhagen accord of 2010 is to provide energy to these impoverished populations. Coal is the only fuel that can sustainably meet growing global demand at such a scale."
