Photovoltaic energy is the result of the physical principle of the photoelectric effect. Under the effect of the solar radiation the photovoltaic cells produce an electric current.
This photovoltaic energy produced is renewable because the source “the sun” is said to be inexhaustible on a human scale. Unlike nuclear energy photovoltaic energy produces very little waste and does not emit pollution.
The countries that produce the most photovoltaic energy in 2014 in the world are China (15.4%) and the United States (11.6%), compared with France at 3.1% photovoltaic on a global scale.
