Answer 83 - Mass of carbon dioxide emitted by natural gas-fired electric power generation for every megawatt hour generated = 2000 / 2 = 1000 pounds = 1000 pounds x (0.4536 kg / pound) x (metric ton / 1000 kg) = 0.4536 metric tons. Total energy generated by natural gas in the world for year 2012 = 6799 million metric tons x (megawatt hour / 0.4536 metric tons) = 14988.977 million megawatt hour = 14988977 gigawatt hour, approximately.
