Chinese businessmen visit an international natural gas equipment exhibition in Beijing

Chinese businessmen visit an international natural gas equipment exhibition in Beijing on April 1, 2011. China just completed its first horizontal shale gas well, after 11 months of drilling, as the world's biggest energy consumer seeks to tap its reserves of the cleaner-burning fuel. China plans to triple the use of natural gas to about 10 percent of energy consumption by 2020 to help cut reliance on more-polluting oil and coal. UPI/Stephen Shaver
