Energy News: "Los Angeles and Pittsburgh provide examples of what to do — and not to do — about China's severe air pollution in the face of surging energy use from rapid economic growth," according to this AP report  of U.S. and Chinese scientists' joint research. They added: "The study released Thursday compared the world's two biggest energy consumers, the United States and China. One of the most important lessons? It makes more sense to try to prevent pollution, rather than clean it up afterward." Also, "We're not saying we're the best example. We're saying, Learn from our experience, look at our successes, but also our failures," said Derek Vollmer, an associate program officer for the National Academy of Sciences, who oversaw the study. "But we have a longer history of dealing with air pollution."
