地球上的各种能源,有的已被大规模开发和广泛利用,如煤炭、石油、天然气、水力等,称常规能源;还有一些能源,如太阳能、风能、地热能、海洋能、氢能、生物质能等,是正在研究开发和利用的能源,被通俗地称为新能源。其实太阳能、风能等,人类很早就已开始利用,这里把它称作新能源,是指在新技术的基础上进行大规模开发利用而言。新能源与常规能源的区分也是相对的,今天的新能源将来也会成为常 Some of the earth’s energy sources, some of which have been extensively exploited and widely used, such as coal, oil, natural gas, water, etc., are called conventional energy sources. Some energy sources such as solar energy, wind energy, geothermal energy, ocean energy, hydrogen energy , Biomass energy, etc., are energy resources that are being researched and developed and are commonly referred to as new energy sources. In fact, solar energy, wind energy, etc., humans have already begun to use very early, here called it a new energy, refers to the new technology in the context of large-scale development and utilization of terms. The distinction between new energy and conventional energy is also relative, and today’s new energy will become a regular
