First of all, "kilowatt" is a rate of energy flow, like miles-per-hour and dollars-per-month.
It's not something that builds up if you let it go for a longer time.
In an on-line search, we found the solar constant ... the total amount of solar power
that the earth receives ... listed as 1.740×1017watts, plus or minus 3.5%.
With 8,765.6 hours in a year, that multiplies out to a total incident energy of
(1.740 x 1017) x (8,765.6) = 1.525 x 1021 watt-hours, or 1.525 x 1018 kilowatt-hours.
That's the amount of solar energy that hits the earth in a year, within a ballpark.
We'll leave it to the questioner to figure out how much of it gets soaked up and
stays here, and how much of it bounces off and is lost.

Where does Earth get its energy from?
The Sun. Earth receives 1370 Watts per square meter of area of solar energy
What is the name of the energy that gets released from the sun?
The energy is called solar energy / power.
How is solar energy made useable?
Solar energy is powered by light emitted by the sun. The sun gets it's energy from nuclear fusion at it' score.
How does Earths Atmosphere Gets Energy?
by the earth's energy being reflected to the atmosphere
How does solar eclipse works?
Solar eclipseThe Sun shines on both the moon and the earth, right? You can perhaps imagine that every once in a while the moon gets between the earth and sun, and blocks the sun out for awhile. That would be a solar eclipse.Lunar eclipseIt is also easy to imagine that sometimes the earth gets in the way of sunlight shining on the moon, and blocks the sun out for awhile. That would be a lunar eclipse.
From were does the earth get solar energy?
The Earth gets its solar energy from the sun. We are the perfect distance away to harvest this resource.
What will happen if earth gets less solar energy?
we don't have power
What type of energy is collected from the sun?
The energy collected from the sun is called solar energy. The energy gets to the earth from the sun by radiation that has been affected by the earth's atmosphere.
How do you define solar energy?
Solar energy can be the suns rays, or it can be space weather. But mostly it's the energy Earth gets from the sun for radiation or it can be reflected back into space.
How is earth atmosphere affected by solar energy?
The earth's atmosphere is affected by solar energy because the energy creates a greenhouse effect. When the radiation of the sun makes the earth too warm, there will be too much greenhouse gas that gets trapped in the atmosphere.
What happens to solar energy that encounters earth and its atmosphere?
Our atmoshere can protect Earth from solar energy,but the atmoshere gets weaker every time it happens.Most of the solar energy doesn't pass ,so does and that's how we get sun burns and skin cancer from ultra violet rays.
How will solar energy improve?
solar energy will improve by not using any coal or oil so that it does not pollute the earth and you will heat your house by using solar energy. <><><><> Possible improvements include lower costs of solar energy system components, higher efficency in the conversion of solar energy, and improvements in storing solar energy (it gets dark at night, y'know?)
Where does Earth get its energy from?
The Sun. Earth receives 1370 Watts per square meter of area of solar energy
When the solar energy reaches the earth where does it go?
Some gets absorbed and converted into other energy forms. Most of the energy will eventually get radiated back into space.
What happens to the energy from the sun when it reaches earth's surface?
What happens to Solar Energy is that some of it gets absorbed into air, land and water while the rest gets reflected back to space.
Why would the earth be cold if it was where Uranus was in the solar system?
Earth gets our energy and heat from the sun. Uranus lies further away from the Sun than Earth which means it does not get as much energy and is thus colder.
Which of the earth receives solar energy at a 90 degree angle?
When sun is overhead its 90 degree. But equatorial region on earth gets more effect.
