Solar power is energy captured from the sun and converted into electricity or heat. Photovoltaic panels turn sunlight directly into electricity, while solar thermal systems use the sun's heat. Because sunlight is free and renewable, solar is one of the fastest-growing clean energy sources worldwide, cutting reliance on fossil fuels.

Solar energy is widely considered environmentally friendly because it produces electricity without burning fuel or releasing carbon emissions during operation. It is renewable, quiet, and needs little maintenance. Manufacturing panels does use resources and energy, but over their lifespan solar systems typically offset far more emissions than they create.
