“If the world continues to use coal the way it has been—I mean China, India, Russia—then it is a pretty bad dream,” Dr. Chu said. China has yet to tackle even coal’s basic particulate pollution problem, he said. But coal is also a “very abundant resource,” Dr. Chu added, making it “imperative” that the U.S. learns to capture carbon-dioxide emissions from coal-fired power plants.
“If confirmed, I will work very hard to extensively develop” clean-coal technology, he said. Nodding to widespread environmental opposition to continued use of coal—clean or otherwise—Dr. Chu said, “Even if we turn off coal, China and India will not.”
