First, you have to understand that it depends on how high the sun is in the sky ...

the lower the sun is, the thinner the sun's power gets spread out when it hits the

ground. That means it all depends on where you are on earth, and what time of

day it is.

All of this is a big part of the reason why it's usually cooler at night and warmer during

the day, and also why it's hotter on the equator and colder in Alaska ... all because of

how high the sun is in the sky.

So maybe the best number we can give you is the average number for the whole earth.

That way it's easier to remember.

If you average it out over all the hot places and cold places on earth, the Tropics, the

deserts, the oceans, the poles, etc., you get one number called the "solar constant",

which is exactly what you're asking for.

The number is roughly 1,160 watts ... about 1.56 horsepower ... on every square yard.

That's not only the light from the sun. It's everything ... light, heat, UV, etc.,

all the energy we get from the sun. Everything you could get and use for free

if you had a way to collect it.

The majority of the sun's radiation output occurs as?

The majority of the sun's radiation output occurs as visible light. This visible light is what we see and feel as sunlight.


What is plasma in the sun?

Plasma in the Sun is the fourth state of matter, consisting of ionized gases. It makes up most of the Sun's mass and is responsible for the nuclear fusion reactions that power the Sun's energy output. Plasma in the Sun has extremely high temperatures and densities, allowing for the continuous release of light and heat.


Why no fission on sun?

The core of the Sun is not dense or hot enough to sustain nuclear fission reactions like those in nuclear power plants. Instead, the Sun undergoes nuclear fusion, where lighter elements are combined to form heavier ones, releasing vast amounts of energy in the process. This fusion process sustains the Sun's energy output and keeps it shining.


A change in Earth's total isolation would be caused by?

A change in Earth's total insulation can be caused by variations in the Sun's output, changes in Earth's orbit, or alterations in the composition of Earth's atmosphere such as increased greenhouse gas concentrations.


Does the sun's energy output remain constant overtime?

Solar output is nearly, but not quite, constant. Variations in total solar irradiance were too small to detect with technology available before the satellite era. As the Earth rotates, the energy from the sun is distributed across the entire surface area. At any given moment, the amount of solar radiation received at a location on the Earth's surface depends on the state of the atmosphere, the location's latitude, and the time of day.

Total power output of the sun: 3.86 x 1023 kilowatts (386,000,000,000,000,000,000,000 kilowatts) Total solar power received on Earth: 1.74 x 1014 kilowatts (174,000,000,000,000 kilowatts) Solar power falling on 1 square meter of ground: 750 watts (0.75 kilowatt) Output of a 1 square meter solar panel: 120 watts (0.12 kilowatt)


How much energy is being used by the sun?

The Wikipedia lists the luminosity - basically the power output - as 3.846×10 to the power 26 Watt (which means, that much joules are output every second). Due to conservation of energy, and assuming the Sun works more or less continuously, that's also the power which is used up inside the Sun.

Would a blue star still be able to possess a habitation zone like our own Sun?

As far as I know, the "habitable zone" is defined in terms of the expected temperature. So, what matters mainly is not the star's color, but its total power output (brightness). In any case, whatever the star's brightness (power output), it is to be expected that there is a certain distance from the star at which the temperature is appropriate.

How does the sun maintain its energy output?

The sun maintains its energy output through nuclear fusion, where it fuses hydrogen atoms into helium in its core. This process releases a tremendous amount of energy in the form of light and heat, which is what sustains the sun's energy output.
