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.
What is the sun s energy source.
The sun s energy comes from thermonuclear fusion reactions.
In stars this energy source comes from gravitational compression which is the contraction of the star under the influence of its own gravity.
It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending.
Sunlight drives plant life via photosynthesis and animals survive by eating plants.
When they do so they release a tremendous amount of energy.
The sun s energy source.
Energy is required to initiate the process since it begins from fusing two hydrogen nuclei that repel each other due to their identical electric charge positive.
The energy that received is then absorbed by the earth s air and crust heating our planet and providing organisms with a source of energy.
It s a crucial question because light and heat from the sun are the basis of almost all life on earth.
The sun is an extremely powerful energy source and sunlight is by far the largest source of energy received by earth but its intensity at earth s surface is actually quite low.
This is essentially because of the enormous radial spreading of radiation from the distant sun.
Because the sun s gravity is so strong hydrogen atoms fuse together to form helium.
The sun is at the center of biological and chemical.
Almost all microscopic forms of life bacteria protozoa etc survive by using the energy of sunlight.
