Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such
as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial
photosynthesis.
It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or
active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar
techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the
energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal
mass or light-dispersing properties, and designing spaces that naturally circulate air.
