由于工农业对热能及动力方面的需求量越来越大,如何更有效地利用和节约有机矿物燃料(煤、石油、天然气等),积极开发、研究和利用新的能源(核能、太阳能、地热、氢、水力、潮汐、风能等),已成为当前不少国家关心的问题。巨大的太阳是人类最基本的能源。地球从太阳一年能获得相当于5.8×10~(17)瓩-小时的能量,要比目前人们利用的各种能源所产生的全部能量约大1～2万倍。太阳能源能提供无公害的动力和热能,它的寿命和太阳本身一样长久。太阳能的利用今天所以在世界各国受到特
As the demand for heat and power in industry and agriculture is increasing, how to more effectively use and save organic fossil fuels (coal, oil, natural gas, etc.), and actively develop, research, and utilize new energy sources (nuclear, solar, geothermal) Hydrogen, hydropower, tides, wind energy, etc. have become issues of concern to many countries. The huge sun is the most basic human energy source. From the sun, the Earth can obtain energy equivalent to 5.8×10 17 瓩-hours a year, which is about 1 to 20,000 times greater than the total energy generated by various energy sources currently used by people. Solar energy sources can provide pollution-free power and heat, and its lifespan is as long as the sun itself. The use of solar energy is today in many countries around the world.
