- 摘要:
受新冠肺炎疫情影响,能源行业受到重大冲击,为梳理能源供需变化情况,在“碳中和”背景下,对2020年全球能源供需资料进行分析。分析结果表明:2020年,全球一次能源消费量下降4.5%,碳排放量下降6.3%,均为1945年以来的最大跌幅;全球石油、天然气和煤炭的产量及消费量均不同幅度降低,其中天然气消费量在一次能源中占比持续上升至24.7%,创历史新高,煤炭仍是发电的最主要能源;可再生能源增长9.7%,在全球总发电量中占比11.7%；在全球能源消费量下跌的情况下,中国是2020年为数不多的各种能源消费量都呈上升趋势的国家之一。分析结果以期为全球能源发展向净零排放提供参考。
Affected by the COVID-19, the energy industry has been greatly impacted. In order to sort out the energy supply and demand changes, this paper analyzed the data of global energy supply and demand in 2020 under the background of “carbon neutrality”. The results show that in 2020, global primary energy consumption decreased by 4.5% and carbon emissions decreased by 6.3%, both of which are the largest decline since 1945. Global production and consumption of oil, natural gas and coal have all declined by varying degrees. Despite the drop in production and consumption, natural gas consumption as a proportion of all non-renewable energy sources continuously rises to 24.7%, hitting a record high. However, coal is still the main energy source for power generation; and renewable energy increased by 9.7%, accounting for 11.7% of the total global power generation. With global energy consumption falling, China is one of the few countries with rising energy consumption in 2020. The analysis results are expected to provide reference for global energy development towards the target of zero net carbon emission.
