Abstract: There is a strong correlation between net energy yield (NEY) and energy return on investment (EROI). Although a few studies have researched the EROI at the extraction level in China, none have calculated the EROI at the point of use (EROI POU ). EROI POU includes the entire energy conversion chain from extraction to point of use. To more comprehensively measure changes in the EROI POU for China’s conventional fossil fuels, a “bottom-up” model to calculate EROI POU was improved by extending the conventional calculation boundary from the wellhead to the point of use. To predict trends in the EROI POU of fossil fuels in China, a dynamic function of the EROI was then used to projections future EROI POU in this study. Results of this paper show that the EROI POU of both coal (range of value: 14:1–9.2:1), oil (range of value: 8:1–3.5:1) and natural gas (range of value: 6.5:1–3.5:1) display downward trends during the next 15 years. Based on the results, the trends in the EROI POU of China’s conventional fossil fuels will rapidly decrease in the future indicating that it is more difficult to obtain NEY from China’s conventional fossil fuels.
