The main source of energy for Earth is the Sun. Solar energy drives many processes critical to life and the planet’s climate system. Through photosynthesis, plants convert sunlight into chemical energy, forming the base of the food chain. The Sun also influences weather patterns, ocean currents, and other natural phenomena. Additionally, solar energy is harnessed directly through technology like solar panels, which convert sunlight into electricity. As a renewable resource, solar energy is vital for sustainable practices and reducing reliance on fossil fuels, making it central to both ecological balance and technological advancements.
