The new rules could have a big impact on emissions and public health.
In the U.S., one-fifth of the coal fleet is at risk of retiring. In the rest of the world, coal demand is soaring.
In recent years, Kentucky and West Virginia's coal industries have been facing a painful decline. Here are all the reasons why.
Large pension funds are now pressing oil, gas, and coal companies to explain how the prospect of carbon regulations might hurt their business.
Since 2008, the world has committed $25 billion to carbon capture — with little to show for it so far.
China currently has plans to build synthetic gas plants to curtail air pollution in the cities. Scientists warn that could have huge unintended consequences.
The new EPA rules will make it very hard to build a new coal plant in the U.S. But cheap natural gas was already making that difficult anyway.
The EPA is unveiling a rule that could make it impossible to build new coal plants in the U.S. for years to come.
As much as 65 percent of the U.S. coal fleet could find itself under threat in the years ahead, thanks to cheap natural gas and stricter air-pollution regulations.
China's current policies to curtail pollution and reduce its coal dependency are failing badly. So here's a look at what the country could do differently.
The decline of coal has left hundreds of thousands of retired miners, many of them with severe ailments, at risk of losing their health and pension benefits.
China's coal use grew 9 percent in 2011, rising to 3.8 billion tons. At this point, the country is burning nearly as much coal as the rest of the world combined.
A new report finds that nearly 1,200 coal plants have been proposed around the world. If a significant portion of those plants got built, it would be extremely difficult to avoid drastic climate change. But for countries like India, deciding whether or not to build those plants is an agonizing question.
John Lotterio, 63, Pennsylvania. "[Obama's] killing people over energy by bottling over all the sources of energy, other than green energy. I saw on TV he said that if you want to invest in coal, go ahead, but you’re going to go bankrupt. What kind of attitude is that from that guy?"
For decades, the U.S. has leased coal on public lands to mining companies at generous rates. But now that more and more of America's coal is getting shipped to countries like China rather than burned at home, critics wonder if U.S. taxpayers are simply subsidizing Asia's coal use.
A look at how the U.S. power sector has evolved over time. Coal and nuclear power used to dominate the landscape. But lately, natural gas and renewables make up the vast majority of new power plants being built.
