物理学与工程技术有着密切的相互联系，能源工程技术与物理学的关系具有典型的代表性，物理学的应用可以对我国能源事业的发展做出重要的贡献。文章着重阐述了原子核物理学和核能工程（包括裂变核能和聚变核能），光电效应与光伏发电，风能、生物质能与物理学，物理化学与煤的多联产、洁净化技术，地球物理学与能源资源勘探等能源问题；讨论了物理学在节能中的三个应用：节能照明、建筑节能和交通节能；分析了中国能源的可持续发展前景。

There is a close correlation between physics and engineering technology, and the relationship between physics and energy engineering is a typical example. Applied physics could make significant contribution to China's energy development.This article discusses some energy problems, such as nuclear physics and unclear energy (including fission and fusion energy) , photoeffect and photovoltaic electricity, physics and wind/bio - mass energy, physicsal chemistry and clean coal technology, and geophysics and energy resource exploration. The article also discusses three applications of physics in energy saving in fields of illumination, building and transportation. Finally, the article analyses the prospects of energy sustainable development in China.
