The main source of energy for the planet is derived from the Sun. Solar radiation provides the energy essential for life on Earth, driving weather patterns, photosynthesis in plants, and maintaining the planet's climate. This energy reaches Earth in the form of sunlight, which is captured by plants for photosynthesis, producing oxygen and organic materials essential for food chains. Additionally, solar energy influences ocean currents and atmospheric conditions, playing a vital role in the water cycle. Beyond its ecological importance, solar energy is increasingly harnessed for human use, offering a renewable resource for electricity and heating.
