...Coal, the nation's favorite fuel in much of the 19th century and early 20th century, could become so again in the 21st. The United States has enough to last at least two centuries at current use rates — reserves far greater than those of oil or natural gas. And for all the public interest in alternatives like wind and solar power, or ethanol from the heartland, coal will play a far bigger role.

But the conventional process for burning coal in power plants has one huge drawback: it is one of the largest manmade sources of the gases responsible for global warming.

Many scientists say that sharply reducing emissions of these gases could make more difference in slowing climate change than any other move worldwide. And they point out that American companies are best positioned to set an example for other nations in adopting a new technique to limit the environmental impact of the more than 1,000 coal-fired power projects on drawing boards around the world.

It is on this issue, however, that executives of some of the most important companies in the coal business diverge. Their disagreement is crucial in the debate over how to satisfy Americans' growing energy appetite without accelerating climate change.

One of those executives, Michael G. Morris, runs American Electric Power, the nation's largest coal consumer and biggest producer of heat-trapping carbon dioxide emissions from its existing plants. He is spearheading a small movement within the energy industry to embrace the new technology. His company plans to build at least two 600-megawatt plants, in Ohio and West Virginia.

The company says these plants are not only better for the environment but also in the best interests of even its cost-conscious shareholders. While they would cost 15 to 20 percent more to build, Mr. Morris says they would be far less expensive to retrofit with the equipment needed to move carbon dioxide deep underground, instead of releasing it to the sky, if limits are placed on emissions of global warming gases.

"Leave the science alone for a minute," Mr. Morris said in an interview at the Columbus, Ohio, headquarters of his company. "The politics around climate issues are very real. That's why we need to move on this now."

But most in the industry are not making that bet. Among them is Gregory H. Boyce, chief executive of Peabody Energy, the largest private-sector coal producer in the world thanks in part to its growing operations here in Wyoming and with aspirations to operate coal-fired plants of its own. Mr. Boyce's company alone controls reserves with more energy potential than the oil and gas reserves of Exxon Mobil.

"We're still not convinced that the technology or cost structure is there to justify going down a path where we're not comfortable," Mr. Boyce said.

Mr. Boyce's view has prevailed. No more than a dozen of the 140 new coal-fired power plants planned in the United States expect to use the new approach.

The decisions being made right now in industry and government on how quickly to adopt any new but more costly technologies will be monumental.
