我国到2050年的一次能源需求预计高达50亿吨标煤/年,这使未来能源发展面临国内常规能源资源供应不足、石油供应缺口巨大、城市需要大量清洁能源以及全球气候变化问题上巨大的国际压力等一系列严峻挑战。该文在对解决上述问题的各种可能途径进行研究分析后,提出了我国未来能源可持续发展的以煤为主多元化的清洁能源战略:一次能源结构中煤仍将占40%以上,大力发展核能和可再生能源以填补国内常规能源资源供应不足,采取以合成燃料为中心的清洁煤战略,实现城市能源以清洁能源为主。——编者 China’s primary energy demand by 2050 is estimated to reach 5 billion tons of standard coal per year, which will confront future energy development with a shortage of domestic conventional energy resources, a huge oil supply gap, a large amount of clean energy in cities and a huge international climate change problem Pressure and a series of harsh challenges. After studying and analyzing various possible ways to solve the above problems, this paper proposes a coal-based diversified clean energy strategy for the future sustainable development of China’s energy resources: coal will still account for more than 40% of the primary energy structure, The development of nuclear power and renewable energy to fill the domestic supply of conventional energy resources, to take a synthetic fuel-based clean coal strategy to achieve urban energy based on clean energy. --editor
