当前,石油、煤、天然气等化石能源仍是世界的主要能源,在世界一次能源供应中约占87.7%,其中,石油占37.3%、煤炭占26.5%、天然气占23.9%。世界非化石能源和可再生能源虽然增长很快,但仍保持较低的比例,约为12.3%。以目前的消费速度,不到100年,世界的石油和天然气等能源资源终将枯竭。 Currently, fossil fuels such as oil, coal and natural gas are still the major energy sources in the world, accounting for 87.7% of the world’s primary energy supply. Among them, oil accounts for 37.3%, coal accounts for 26.5% and natural gas accounts for 23.9%. Although the world’s non-fossil energy and renewable energy are growing rapidly, they still maintain a relatively low proportion of about 12.3%. At the present rate of consumption, in less than 100 years, the world’s energy resources such as oil and natural gas will eventually dry up.
