Solar power is defined as the energy produced by converting sunlight into heat or electricity. It is one of the most abundant and affordable sources of energy available. However, it is difficult to harness (and even impractical) in some parts of the world, so it is important to explore the process of converting sunlight to power. Shows three primary ways to produce solar power on a large scale: solar power–generating plants, photovoltaic cells, and solar thermal heaters. Accessibility options on the DVD are: (1) expanded description, (2) English subtitles in a black box, (3) subtitled description.
