太阳能(solar energy)，是指太阳的热辐射能(参见热能传播的三种方式:辐射)，主要表现就是常说的太阳光线。在现代一般用作发电或者为热水器提供能源。自地球上生命诞生以来，就主要以太阳提供的热辐射能生存，而自古人类也懂得以阳光晒干物件，并作为制作食物的方法，如制盐和晒咸鱼等。在化石燃料日趋减少的情况下，太阳能已成为人类使用能源的重要组成部分，并不断得到发展。太阳能的利用有光热转换和光电转换两种方式，太阳能发电是一种新兴的可再生能源。广义上的太阳能也包括地球上的风能、化学能、水能等。扭王块模具 高铁遮板模具 阶梯护坡模具 拱形护坡模具 卵形槽模具 保定室内设计培训 保定平面设计培训
Solar energy refers to the thermal radiant energy of the sun (see three ways of thermal energy transmission: radiation), which is mainly represented by the often said solar light. In modern times, it is generally used to generate electricity or provide energy for water heaters. Since the birth of life on earth, it has mainly lived with the thermal radiation energy provided by the sun. Since ancient times, humans also know how to dry objects with the sun as a way to make food, such as salt and salted fish. With the decrease of fossil fuels, solar energy has become an important part of human energy and has been developing continuously. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is a new renewable energy. In a broad sense, solar energy also includes wind energy, chemical energy, water energy, etc.
