International Energy Outlook (IEO) of the US Energy Information Administration and World Energy Outlook (WEO) of the <a href="https://www.sciencedirect.com/topics/engineering/international-energy-agency" rel="noopener noreferrer" target="_blank">International Energy Agency</a> publish widely used energy projections, whose accuracy for China – the largest energy consuming economy and carbon dioxide emitter – has been rarely explored. This study investigates accuracy of China's reference energy projections in the annual reports of IEO and WEO from 2004 to 2019. Results show that most projections in IEO and WEO underestimated China's total energy consumption, particularly over longer projection horizons. The use of coal, natural gas and renewable energy tended to be underestimated, and nuclear energy was overestimated. The errors of industry and transport sectors were comparable and higher than for the other sectors. WEO showed substantially better accuracy than IEO in projections of total energy consumption, <a href="https://www.sciencedirect.com/topics/engineering/primary-energy-resource" rel="noopener noreferrer" target="_blank">primary energy resources</a> (except for nuclear energy) and end-use sectors. Projection horizon, errors in projected population's size, oil price and gross domestic product per capita were four leading factors related to the projection errors and hence they require particular attention in future modeling. For policy makers, this study shows that, if IEO and WEO projections are used to guide the policy making, China needs more aggressive policies in order to achieve the carbon neutrality goal.</p> Energy projections Accuracy Energy system modeling Model evaluation International energy outlook World energy outlook Dewey 550 Dewey 333.7-333.9 Swiss National Science Foundation Accuracy of long-range national energy projections (ACCURACY) 186834 CH Careers 41 Département F.-A.
