%0 Journal Article %J Science Advances %D 2020 %T Offshore wind: an opportunity for cost-competitive decarbonization of China’s energy economy %A Sherman, Peter %A Chen, Xinyu %A McElroy, Michael B. %X China has reduced growth in its emissions of greenhouse gases, success attributable in part due to major investments in onshore wind. By comparison, investments in offshore wind have been minor, limited until recently largely by perceptions of cost. Assimilated meteorological data are used here to assess future offshore wind potential for China. Analysis on a provincial basis indicates that the aggregate potential wind resource is 5.4 times larger than current coastal demand for power. Recent experiences with markets both in Europe and the US suggest that potential offshore resources in China could be exploited to cost-competitively provide 1148.3 TWh of energy in a high-cost scenario, 6383.4 TWh in a low-cost option, equivalent to between 36% and 200% of the total coastal energy demand post 2020. The analysis underscores significant benefits for offshore wind for China, with prospects for major reductions greenhouse emissions with ancillary benefits for air quality. %B Science Advances %V 6 %P eaax9571 %G eng %U https://advances.sciencemag.org/content/6/8/eaax9571 %N 8
