ChinaThe primary energy sources in China are shown in Fig. 14. The importance <strong>of</strong> coal use can easily be seenfrom the figure. The increasing use <strong>of</strong> coal has had a distinct impact on the CO 2 emissions as well as theincreasing use <strong>of</strong> oil especially in the transport sector. It seems that until 2007 there has not been muchincrease in the use <strong>of</strong> renewable energy.2500Primary energy sources in China (Mtoe)200015001000500Combustible renewablesHydroNuclearNatural gasPetroleum productsCrude oilCoal <strong>and</strong> coal products01971 1980 1990 2000 2007Figure 14. Primary energy supply in China. Data source (IEA 2009).The results <strong>of</strong> the decomposition analysis <strong>of</strong> factors contributing to the CO2 emissions is shown inFig. 15. Again here the percentage figures are remarkably large due to the very low starting level <strong>of</strong>emissions in the year 1971, which serves as the reference value. The shift to fossil fuel dominated energysystem can be seen in the factor CO 2 /TPES. Also the shift to increased electricity share <strong>of</strong> final energyconsumption is observable in the component TPES/FEC: On the one h<strong>and</strong>, the energy intensity <strong>of</strong> theChinese production system has decreased considerably contributing to the reduction <strong>of</strong> emissions but onthe other h<strong>and</strong>, the huge economic growth <strong>and</strong> population growth have contributed in increasing theemissions.483
