Solar Energy

Solar technologies are broadly characterized as either or depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable or light dispersing properties, and designing spaces that Solar energy, radiant and rom the has been harnessed by humans since using a range of ever-evolving technologies. Solar along with secondary solar-powered resources such as and and account for most of the available on earth. Only a minuscule fraction of the available solar energy is used.

electrical generation relies on and Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through via and, and high temperature process heat for industrial purposes

.To harvest the solar energy, the most common way is to use Earth's land surface, and atmosphere absorb solar radiation, and this raises their temperature. Warm air containing evaporated water from the oceans rises, or When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the he of water condensation amplifies convection, producing atmospheric phenomena such as and Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14  By green plants convert solar energy, which produces food, wood and the from which fossil fuels are derivedThe Earth receives 174  W) of incoming solar radiation) at the upper Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses.

Solar technologies are broadly characterized as either passive or active depending on the way they capture, convert and distribute sunlight. Active solar techniques use photovoltaic panels, pumps, and fans to convert sunlight into useful outputs. Passive solar techniques include selecting materials with favorable thermal properties, designing spaces that naturally circulate air, and referencing the position of a building to the Sun. Active solar technologies increase the supply of energy and are considered technologies, while passive solar technologies reduce the need for alternate resources and are generally considered demand side technologies.
