2021年全球水电发展现状与开发潜力分析

为全面了解全球水电发展现状、分析全球水电开发及国际水电市场发展潜力,基于国际水电协会发布的年度报告,通过分析近几年全球水电发展现状发现,全球水电总装机容量持续增加,受各国疫情防控与2050碳中和目标双重影响,2021年增量虽未达到预估的2%但较2020年增速仍有回升。结合全球水电资源开发情况,分析了全球水电开发的潜力,发现亚洲、南美洲、非洲、北美洲开发潜力较大,中国、巴西、俄罗斯、加拿大、美国水电总体发展潜力名列前茅,不丹、冰岛、巴布亚新几内亚、圭亚那、加蓬人均水电潜力较大。

Global hydropower development status and potential analysis in 2021

In order to comprehensively understand the current situation of global hydropower development, and to analyze the development potential of global hydropower and the international hydropower market,the current situation of global hydropower development in recent years was analyzed based on the hydropower annual reports released by the International Hydropower Association. It is found that the total installed capacity of global hydropower continues to increase, and affected by the continuous COVID-19 and the 2050 carbon neutrality target,the increaserate was still rebounded although it did not reach the estimated 2%. Combined with the development of global hydropower resources, the potential of global hydropower development was analyzed. The results show that Asia, South America, Africa, and North America have great developmentpotential. China, Brazil, Russia, Canada, and the United States are among the best in overall hydropower potential. Bhutan, Iceland, Papua New Zealand Guinea, Guyana, and Gabon have relatively large hydropower potential per capita.
