Solar Energy
Solar energy is created by nuclear fusion that takes place in the sun. It is necessary for life on Earth, and can be harvested for human uses such as electricity.

Solar energy - Electricity Generation: Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.
Solar power works by converting energy from the sun into power. There are two forms of energy generated from the sun for our use – electricity and heat. Both are generated through the use of solar panels, which range in size from residential rooftops to 'solar farms' stretching over acres of rural land. Is solar power a clean energy source?
A solar photovoltaic system produces electricity directly from the sun's light through a series of physical and chemical reactions known as the photovoltaic effect. Let's examine each of these systems in more detail.
In most places on Earth, sunlight's variability makes it difficult to implement as the only source of energy. The Agua Caliente Solar Project, in Yuma, Arizona, United States, is the world's largest array of photovoltaic panels. Agua Caliente has more than five million photovoltaic modules, and generates more than 600 gigawatt-hours of electricity.
