Solar energy—power from the sun—is a vast and inexhaustible resource that can supply a significant portion of global electricity needs. In the United States, over two million households already have solar panels on their roof; utilities and companies across the country are also investing in solar farms to capture the sun’s energy at a larger scale. Solar power is essentially carbon-free. A small amount of pollution is created during the manufacturing process, and disposal is an ongoing challenge; however, the fuel used (the sun) is free, is plentiful, and doesn’t pollute.
