我国主张以非化石能源替代化石能源。在非化石能源中,能够真正成为替代能源的是核能和太阳能(指太阳能直接利用)。核能和太阳能的数量都很大,如果不考虑安全和经济性,那么核能优于太阳能,因为:(1)核能的能量密度大,大于煤炭、石油和天然气;(2)核能是连续的发电能源,而太阳能属于间歇性、随机性能源;(3)核能可以成为替代能源,而太阳能属于辅助性能源,需要化石能源联合运行或者与蓄能装置配合运行才能成为替代能源。但是核能有热堆、快堆和聚变堆,真正能源数量大的是核聚变,所以我们希望核聚变能早日成为可行性能源。
My country advocates replacing fossil fuels with non-fossil fuels. Among non-fossil fuels, nuclear energy and solar energy (referring to the direct use of solar energy) can really become alternative energy sources. Nuclear and solar energy are large in number, and nuclear energy is superior to solar energy if safety and economy are not considered because: (1) the energy density of nuclear energy is greater than that of coal, oil and natural gas; (2) nuclear energy is a continuous source of electricity , While solar energy is an intermittent and random energy source. (3) Nuclear energy can become an alternative energy source. Solar energy is an auxiliary energy source and needs fossil fuels to operate jointly or with energy storage devices to become an alternative energy source. However, there are thermal reactors, fast reactors and fusion reactors in nuclear power. Nuclear fusion is the major source of energy. Therefore, we hope nuclear fusion will soon become a viable energy source.
