Solar energy is the source of all the energy on the earth, and the sun shines on every part of the earth. Wind energy is another form of solar energy on the surface of the earth. Due to different forms of the earth’s surface (such as sand, ground, vegetation, ground and water), the absorption coefficient of solar radiation is different, resulting in the formation of temperature difference on the ground surface, and then the formation of air convection wind energy. Therefore, wind energy and solar energy have strong complementarities both in time and in seasons: During the day, the sun shines well, the wind is small, at night there is no light, the wind is stronger; In summer, the intensity of the sunlight is large and the wind is small, and the sunlight intensity is weak and windy in winter. The wind energy and solar energy resources in Inner Mongolia also have such complementary characteristics. The wind energy and solar energy resources in a certain place in Inner Mongolia are use...
