Here's a snippet from a New York Times article with the reassuring title: "With China and India Ravenous for Energy, Coal’s Future Seems Assured":
Coal remains a critical component of the world’s energy supply despite its bad image. In China, demand for coal in 2010 resulted in a traffic jam 75 miles long caused by more than 10,000 trucks carrying supplies from Inner Mongolia. India is increasing coal imports.
So is Europe, as it takes advantage of lower coal prices in the United States. …
Global demand for coal is expected to grow to 8.9 billion tons by 2016 from 7.9 billion tons this year, with the bulk of new demand -- about 700 million tons -- coming from China, according to a Peabody Energy study. China is expected to add 240 gigawatts, the equivalent of adding about 160 new coal-fired plants to the 620 operating now, within four years. During that period, India will add an additional 70 gigawatts through more than 46 plants.
