Unfortunately this question is a trick question... The sun is NOT the source of ALL energy on the earth.
Some bacteria do not need sunlight to survive. They live next to
hydrothermal vents in the deep sea, far below a depth which sunlight can penetrate. Hydrothermal vents release superheated water with dissolved minerals and sulfur into the ocean. The bacteria use the oxygen and carbon dioxide in the seawater along with the sulfur from the vents to produce food. This process is known as chemosynthesis.
Volcanic activity under the surface of the earth has the potential for extreme amounts of energy. But to this day it has been difficult to harness that energy.

The sun isn't the source of all energy on the earth. There are two sources actually. The sun and the turning of the earth due to the gravity pull of all of the planets in the solar system.
The turning of the earth by itself creates the incrediable gravity and friction that cause the high heat in the earth's core. The sun has little to do with that.
The combination of those two energy sources are what create all living conditions on the earth.

If you trace back all the energy sources that we have on earth, they are all a direct influence of the Sun's energy.
Fossil fuels for example - oil, gas, coal, were formed from decayed plant matter. The energy in this fuel was the energy stored by the plant, which came from the sun.
Wind power is caused, by, well, the wind. Winds are caused by convection, or differences in temperature. These differences in temperature have to do with the sun.
Hopefully this gives you the bigger picture!

dont really know but it gives plants and other things energy and widout the sun certain things cant produce r do anythin really so its pretty much the source of energy plus u can even get solar energy to do certain things...i aint sure science isnt really my strongest subject srry i cudnt b of more help

its light is for fotosyntheses
its warmth is for you
