如果说,能源主要都源于核能,您会相信吗?太阳能太阳能非常巨大。理论计算表明,太阳每秒钟辐射到地球上的能量相当于500多万吨煤燃烧时放出的热量,累积一年下来约合170万亿吨煤的热量,现在人类活动一年消耗的能量还不及它的万分之一。太阳能到达地球表面后,被植物吸收的只占千分之一二,并转变成化学能贮存起来,其余绝大部分都转换成热,散发到宇宙空间去了。
If you say that the main source of energy from nuclear energy, you believe it? Solar energy solar energy is very huge. Theoretical calculations show that the sun radiates energy to the earth equivalent to the heat emitted by more than 5 million tons of coal burning per second, accumulating about 170 trillion tons of coal a year, and the amount of energy that human activities consume for one year now Less than one ten thousandth of it. When solar energy reaches the Earth’s surface, it absorbs only one-twelfth of a million plants and turns it into chemical energy for storage. Most of the rest is converted into heat and emitted to the universe.
