What Is The Sun S Energy Source

Almost all microscopic forms of life bacteria protozoa etc survive by using the energy of sunlight.

What is the sun s energy source.

Learn the basics of how the sun serves as the ultimate energy source for much of the energy we use including fossil fuels from the national academies advisers to the nation on science engineering and medicine. The sun s energy comes from thermonuclear fusion reactions. This is essentially because of the enormous radial spreading of radiation from the distant sun. Sunlight drives plant life via photosynthesis and animals survive by eating plants.

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. 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. It s a crucial question because light and heat from the sun are the basis of almost all life on earth.

It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. The sun is at the center of biological and chemical. Sunlight is earth s predominant source of energy. 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.

In stars this energy source comes from gravitational compression which is the contraction of the star under the influence of its own gravity. What is the source of the sun s energy.
