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. What is the source of the sun s energy. 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. 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. 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.

It s a crucial question because light and heat from the sun are the basis of almost all life on earth. Sunlight is earth s predominant source of energy. In stars this energy source comes from gravitational compression which is the contraction of the star under the influence of its own gravity. The sun s energy comes from thermonuclear fusion reactions.

Sunlight drives plant life via photosynthesis and animals survive by eating plants. 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. Because the sun s gravity is so strong hydrogen atoms fuse together to form helium.

When they do so they release a tremendous amount of energy. The sun s energy source.
