一、太阳能的利用在我们国家实现四化的同时,尚面临着一项严峻的能源和环境问题。据科学家们测算,地球上非再生能源的储量只够用数百年了。但太阳能却是分布极广而取之不尽。在我国每年从太阳获得的能量已相当于12000亿吨标准煤具有的能量,并且太阳能没有任何污染,也不影响生态平衡。因此,世界各国以节能和保护环境为目标,非常重视太阳能
First, the use of solar energy in our country to achieve the four modernization, is still facing a serious energy and environmental issues. According to scientists’ calculations, the earth’s non-renewable energy reserves are only enough for hundreds of years. However, solar energy is widely distributed and inexhaustible. In our country, the annual energy obtained from the sun is equivalent to the energy of 1.2 billion tons of standard coal, and there is no pollution of solar energy and it does not affect the ecological balance. Therefore, all countries in the world aim at energy conservation and environmental protection and attach great importance to solar energy.
