A coal power plant in Datteln, Germany. Per capita energy consumption rose by 33 percent between 1990 and 2005. Between 2005 and 2030, per capita energy consumption is expected to increase another 18 percent, meaning that global consumption will rise by 50 percent. The majority (86 percent) of the world's energy needs are met by fossil fuels. When burned, fossil fuels release nitrous oxides (NOx) into the air which can eventually be transported to surface waters through the process of wet and dry deposition.
