Nothing is very essential on the planet than the Sun. In absence of heat and light of Sun, our planet Earth would be an ice-coated lifeless rock. The Sun stirs our atmosphere, warms our seas, produces different weather patterns, and provides energy to the growing plants that in turn provide the oxygen and food for survival on the planet. Sun benefits all the living creatures on Earth in numerous ways.
How does Sun impact our daily life?
Photosynthesis: When the rays of the sun pass through the atmosphere of Earth, its energy is received by plants as infrared light radiation and visible light. They convert this energy into the form of chemical energy (starches and sugars) via the method called photosynthesis. To perform this process, they also use carbon dioxide gas, photons, and water. The green pigment present in the leaves is known as chlorophyll that traps the energy of the Sun.
Solar Energy: It is the process of transformation of the Sun’s energy into electricity. Solar energy is used in rural areas, remote regions, and space where power supplies are not present. Due to the affordability of renewable solar energy, it has now been seen as a competitive source of energy in comparison to other energy sources such as oil or coal.
Several technologies help in accomplishing this task. Solar power plants are used for the conversion of sunlight into electricity. Photovoltaic cells use concentrated solar power for the same purpose.
Uses of solar energy:
- Many households use this natural form of energy in heating, drying, and cooking purpose.
- Solar cookers are nowadays used to cook food with the help of Sun’s energy.
- To produce electricity via heat engines or solar cells
- To remove salt from seawater.
- To use the heat of the sun’s rays to dry towels and clothes.
- Used by plants for performing photosynthesis procedure.
Health Benefits of Sun
Besides the above benefits, there are many ways in which sunlight benefits the human body.
