The primary source of energy on Earth is the Sun. Solar energy drives various processes, including photosynthesis in plants, which enables them to convert sunlight into chemical energy, forming the base of the food chain. Solar energy influences weather patterns and ocean currents, affecting climate and ecosystems globally. It is harnessed using various technologies, such as solar panels, to generate electricity or heat. While fossil fuels have long been the dominant energy source for civilization, a significant shift towards solar and other renewable energy sources is essential for sustainability and combating climate change.
