The purpose of solar energy is to harness the power of sunlight and convert it into usable forms of energy such as electricity or heat. Solar energy is considered a renewable and sustainable source, aiming to provide an environmentally friendly alternative to traditional fossil fuels. By capturing sunlight through technologies like solar panels, solar thermal systems, or solar cells, the goal is to generate clean energy, reduce dependence on non-renewable resources, and mitigate the environmental impact associated with conventional energy production.
