<P> Greenhouse gases are not the only emissions of energy production and consumption . Large amounts of pollutants such as sulphurous oxides (SO), nitrous oxides (NO), and particulate matter (PM) are produced from the combustion of fossil fuels and biomass; the World Health Organisation estimates that 7 million premature deaths are caused each year by air pollution . Biomass combustion is a major contributor . In addition to producing air pollution like fossil fuel combustion, most biomass has high CO emissions . </P> <P> Total primary energy supply of 13,699 mega-toe by source in 2014 (IEA, 2016) </P> <P> The twentieth century saw a rapid twenty-fold increase in the use of fossil fuels . Between 1980 and 2006, the worldwide annual growth rate was 2% . According to the US Energy Information Administration's 2006 estimate, the estimated 471.8 EJ total consumption in 2004, was divided as given in the table above, with fossil fuels supplying 86% of the world's energy: </P> <P> In 2000, China accounted for 28% of world coal consumption, other Asia consumed 19%, North America 25% and the EU 14% . The single greatest coal - consuming country is China . Its share of the world coal production was 28% in 2000 and rose to 48% in 2009 . In contrast to China's ~ 70% increase in coal consumption, world coal use increased 48% from 2000 to 2009 . In practice, the majority of this growth occurred in China and the rest in other Asia . China's energy consumption is mostly driven by the industry sector, the majority of which comes from coal consumption . </P>
