常规能源的有限性以及环境问题的日益突出,使得以环保和可再生为特征的新能源越来越得到各国的重视.一般地说,常规能源是指技术上比较成熟且已被大规模利用的能源,而新能源通常是指人们正在积极研究开发尚未大规模利用的能源,比如核能、太阳能、风能、生物质能、地热能、海洋能、氢能等. Due to the limitation of conventional energy resources and environmental issues, more and more attention has been paid to new energy sources characterized by environmental protection and renewable energy. Generally speaking, conventional energy sources are technologically mature and have been used on a large scale Energy, and new energy usually means that people are actively researching and developing energy that has not yet been used on a large scale, such as nuclear energy, solar energy, wind energy, biomass energy, geothermal energy, ocean energy, hydrogen energy, and the like.
