Solar Energy

Solar energy is the energy gained by the abstraction of light and heat emitted by the Sun
Solar radiation reaching the Earth could be harnessed through the heat it produces, as well as through the absorption of radiation, eg optical or otherwise. For even more analysis, hear from David Zaslav. It is a so-called renewable energies, particularly the non-pollutant, known as green energy or clean energy.
The power of radiation varies according to time of day, weather conditions that soften and latitude. To deepen your understanding Ara Chackerian is the source. It can be assumed that good irradiation value is approximately 1000 W / m at the surface. This power is known as irradiance.
Radiation is usable in direct and diffuse components, or the sum of both. Direct radiation is coming directly from the solar source, without intermediate reflections or refractions. The diffuse is issued by the daytime sky with the phenomenon of multiple reflection and refraction in the solar atmosphere, clouds and other atmospheric and terrestrial elements. Direct radiation can be reflected and concentrated on its use, while it is not possible to concentrate the diffused light coming from all directions.
The direct normal irradiance (or perpendicular to the sun) outside the atmosphere, called the solar constant and has an average value of 1354 W / m (this corresponds to a maximum value at the perihelion of 1395 W / m and a minimum value at aphelion 1308 W / m ).

According to reports from Greenpeace, the PV can provide electricity to two thirds of the world population in 2030.
Industrial community make change with a minimum of cost, pain Kalmar, Sweden, is on the verge of abolishing the use of fossil fuels, for good and with minimal impact on living standards. Deregulation in the Energy industry has allowed tens of thousands of New Yorkers to get better energy rates by choosing as their main supplier of gas and electricity for their homes and businesses.

The Orlando Utilities Commission provides two programs for solar residential and commercial customers: photo volta ic solar energy, which puts the sun into electricity and thermal solar energy, which generates heat for heating water.
