Here's an example of an expository text about "solar energy":
Solar energy is a clean, renewable energy source that is superior to the sun's light and heat. Solar energy has a wide range of applications, such as power generation, hot water**, lighting, and more. This article will detail the principles, benefits, and applications of solar energy.
First, let's understand how solar energy works. Solar energy is the process of converting sunlight into electricity through solar panels. Solar panels are usually made of semiconductor materials such as silicon, and when sunlight hits the panels, the photons interact with the electrons in the semiconductor material, creating an electric current. This process is known as the photoelectric effect.
Solar energy has many advantages. First of all, solar energy is an endless source of energy. The Sun is the most important energy in our universe**, and its lifespan is expected to be billions of years. Therefore, the use of solar energy can not only meet the energy needs of humans, but also reduce the dependence on other finite resources. Second, solar energy is a clean source of energy. Compared to fossil fuels, the development and use of solar energy does not produce greenhouse gases and pollutants and has less environmental impact. In addition, the operation and maintenance cost of the solar energy system is low, and it has good economic benefits.
Solar energy has a wide range of applications in many fields. For example, solar power systems can provide clean, renewable electricity to homes and businesses. Solar water heating systems can provide hot water to homes and reduce energy consumption. Solar street lights can provide illumination for roads and squares at night, saving energy. In addition, solar energy is also used in aviation, navigation and other fields. Expository text
