Solar energy utilization and energy crisis and environmental issues

Solar energy utilization and energy crisis and environmental issues

Basic way of using solar energy The basic ways of using solar energy can be divided into the following four categories. 1. Light and heat utilization Its basic principle is to collect solar radiant energy and convert it into heat energy through interaction with matter for use. At present, the most used solar energy collectors

2. Air quality Due to the presence of the atmosphere, solar radiation energy will be greatly attenuated before reaching the ground. The magnitude of this attenuation is closely related to the length of the solar radiation energy travel through the atmosphere. The longer the distance the sun’s rays travel through the atmosphere, the more energy is

The seventh and eighth stage of the brief history of solar energy utilization

1. The seventh stage: 1981~1991 The upsurge of solar energy development and utilization that started in the 1970s began to ebb shortly after entering the 1980s, and gradually entered a trough. Many countries have drastically reduced solar energy research funds one after another, of which the United States is the most prominent. The main reasons for

The sixth stage: 1973~1980 Since oil replaced coal in the world’s energy composition, it has become an important factor in the world economy and the survival and development of a country. The Middle East war that broke out in October 1973 forced the Organization of the Petroleum Exporting Countries to use oil as a weapon
The first few stages of the brief history of solar energy utilization

The first few stages of the brief history of solar energy utilization

Although mankind has used solar energy for more than 3,000 years, the use of solar energy as an energy and power source has a history of less than 400 years. According to the development and application of solar energy, the development process of solar energy utilization in the modern world can be divided into eight
