How much energy does the sun give off in one day?

Answer 1

The average total energy output of the sun each second is about 3.8×1026 J (i.e. J/s)

The power flux reaching the top of the Earth's atmosphere is about 1400 Watts/m2 (1400 J/s per m²)

Sensors aboard NASA's satellites over the 1979-99 interval suggest it varied by only about 0.2%.

Answer 2

It is derived from the nuclear fusion of hydrogen nuclei to make helium, energy is released as heat and is then radiated outwards in all directions, the earth intercepts a small amount of this total. It actually comes to us as EM radiation in the infra-red, ultra-violet, and visible light frequencies

Answer 3

The sun shines on half of the Earth at all times and delivers an enormous amount of energy in the form of light energy. If the sun is directly overhead, there is about a thousand watts of light energy delivered to each square meter. As the angle of the sun changes, the amount of energy changes as a matter of basic geometry so that at sunset the energy approaches zero.

Most of the energy (53%) delivered by the sun is in the form of infrared and longer wavelengths that can not be seen by the human eye and that energy is largely absorbed and results in heat. A large amount of energy arrives as visible light (44%) with about 3% of the energy in the higher frequencies of ultraviolet.

The effect of the Earth's atmosphere is to decrease the light hitting Earth directly. There is about 30% more energy that arrives at the top of the atmosphere and is either absorbed, scattered before it reaches ground level.

Answer 4

The average total energy output of the sun each second is about 3.8×1026 J (i.e. J/s)

The power flux reaching the top of the Earth's atmosphere is about 1400 Watts/m2 (1400 J/s per m²)

Sensors aboard NASA's satellites over the 1979-99 interval suggest it varied by only about 0.2%.

Answer 5

The sun gives off about 4 x 10^26 watts of energy every second. Multiplying this by the number of seconds in a day (86,400) gives a total energy output of approximately 3.5 x 10^31 joules in one day.

Answer 6

how much energy does the sun give off in a day?

Answer 7

0.000000014% of its energy on an average day

Answer 8

The same amount that the USA uses every year in one second.

Answer 9

Electromagnetic radiation in the infra red, visible, and ultra violet frequency ranges

Answer 10

According to the Wikipedia, 3.846×1026 Watts. (Watt is a unit of power, equivalent to joules per second.)
