knowledge is the adornment and protection of the Empire: Motto of Imperial College London: scientia ipsa potentia est: knowledge itself is power: Stated originally by Sir Francis Bacon in Meditationes Sacrae (1597), which in modern times is often paraphrased as scientia est potestas or scientia potentia est (knowledge is power). scientia, labor ...
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current . [ 2 ]
In critical theory, power-knowledge is a term introduced by the French philosopher Michel Foucault (French: le savoir-pouvoir).According to Foucault's understanding, power is based on knowledge and makes use of knowledge; on the other hand, power reproduces knowledge by shaping it in accordance with its anonymous intentions.

From 2011 to 2021, renewable energy grew from 20% to 28% of global electricity supply. Power from the sun and wind accounted for most of this increase, growing from a combined 2% to 10%. Use of fossil energy shrank from 68% to 62%. [7] In 2022, renewables accounted for 30% of global electricity generation and are projected to reach over 42% by ...

Solar cells produce direct current electricity from sunlight which can be used to power equipment or to recharge batteries. The first practical application of photovoltaics was to power orbiting satellites and other spacecraft , but today the majority of photovoltaic modules are used for grid-connected systems for power generation.
Sunlight on the surface of Earth is attenuated by Earth's atmosphere, so that less power arrives at the surface (closer to 1,000 W/m 2) in clear conditions when the Sun is near the zenith. [100] Sunlight at the top of Earth's atmosphere is composed (by total energy) of about 50% infrared light, 40% visible light, and 10% ultraviolet light. [101]
But he makes a very important distinction, "sun is not sight" but it is "the cause of sight itself." As the sun is in the visible realm, the form of Good is in the intelligible realm. It is "what gives truth to the things known and the power to know to the knower". It is not only the "cause of knowledge and truth, it is also an object of ...
