A new leaf: Scientists turn carbon dioxide back into fuel. Researchers have found a way to convert carbon dioxide into a usable energy source. Carbon dioxide is produced by the burning of fossil fuels in power plants and car engines and it continues to accumulate in the atmosphere, warming the planet. The trees and other plants do slowly capture carbon dioxide from the atmosphere, converting it to sugars that store energy. Scientists and policymakers around the world try to combat the increasing rate of climate change, they have focused on the chief source which is carbon dioxide.In a new study from the U.S. Department of Energy's Argonne National Laboratory and the University of Illinois at Chicago, researchers have found a similar way to convert carbon dioxide into a usable energy source using sunlight. more
