Light (particularly sunlight) can be used to create heat or generate electrical power. This is referred to as solar energy.It is a clean form of energy production, which doesn't pollute the environment as some other forms of energy production do.There are two forms of solar energy. The first is solar thermal conversion, which uses sunlight to create heat and then electrical power. The second is photovoltaic conversion, which uses sheets of special materials to create electricity from the sun. "Photo-" means "light," and "voltaic" means "producing electricity."
