一、概述太阳能是巨大的能源,是一种取之不尽,用之不竭的自然能源.太阳一年中辐射给地球的能量约152亿亿千瓦小时,这些能量比地球蕴藏的煤和石油的总能量约多一百倍,等于全球每年消耗各种能量的一至二万倍.我国幅员辽阔,太阳能资源丰富,全国三分之二的面积全年日照2000小时以上,是研究和利用太阳能的有利条件.自1973年能源危机以来,世界各国都在寻找新的能源,除继续勘探石油和煤以外,
I. Overview Solar energy is a huge source of energy. It is an inexhaustible source of natural energy. The annual radiation of energy from the sun to the earth is about 152 billion kilowatt-hours, which is more than the amount of coal and oil in the earth. The total energy is about one hundred times more than that of the world, which is equivalent to one to twenty thousand times of the annual consumption of all kinds of energy in the world. China is a vast country with abundant solar energy resources. It has more than two-thirds of the country’s total area sunshine for more than 2,000 hours a year. It is a research and use of solar energy. Advantageous conditions. Since the energy crisis in 1973, all countries in the world have been looking for new energy sources, in addition to continuing to explore oil and coal.
