Answer
Approximately 120,000 TW (terrawatts)

That is 120000000000000000 joules per second!

More energy hits the Earth from the Sun in one hour that the whole world uses all year.
(The world uses 15 terrawatts of power per year.)

About 51% of solar energy reaching the earth is absorbed by the Earth's surface.

  • Incoming solar radiation: 100%
  • Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%
  • Continuing incoming solar radiation: 78%
  • Reflected by clouds: 20% : Absorbed by clouds: 3%
  • Continuing incoming solar radiation: 55%
  • Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%

I don't believe any Earth is used in solar energy since solar energy is when the light of the sun is converted to energy used on earth.

How much of the Earths land surface do plains regions cover?

Deserts cover 33% of the land surface of the earth.


Does the land area or water area of Earth's surface absorb more solar energy?

Short Answer:Since there is so much more water than land, one expects that most of the solar energy absorbed by Earth is absorbed into the oceans. That is correct.Crudely, twice as much energy is absorbed by the oceans as the land since there is roughly a bit more than twice as much ocean as land.More Technical (Albedo):The characterization of how much solar energy is absorbed by a portion of the surface of the Earth is something called the albedo of the surface. Some surfaces, like dirt, forests and the ocean absorb most of the Sun's energy. Others, like Snow reflect most of it. Deserts are in between.The albedo of a surface is the fraction of light it reflects. (The term "reflects" does not mean like a mirror but rather means scatters or causes to light bounce back to distinguish "reflection" from the process where light is absorbed.) Normally, one refers to sunlight when quoting an albedo, but if a different or specific wavelength range is being considered, there are different values of the albedo that are defined for different parts of the electromagnetic spectrum.On average, the ocean surface has a low albedo meaning it absorbs most of the light that gets to it.The same is true for bare soil and most forests.Though the albedo is variable, 70 or 80 % of the light is absorbed.Desert areas typically have high albedos and can reflect most of the light.Most land areas are in an albedo range of 0.1 to 0.4, so 90% to 60% of the light is absorbed.The average albedo of the Earth is about 0.3, somewhat higher than typical of oceans or much of the land area primarily because of the contribution of clouds.Clouds reflect light very effectively, absorbing little.


How much of earths surface is covered by salt water only?

Approximately 67.8% of earth's surface is covered by salt water while only 3% is covered by fresh water. In total, the earth's surface is covered by 70.8% of water.


What types of lava eruptions cover the largest area on earths surface?

Sheiks volcanos because they usually have not that much silica but iron and magnesium making it like a liquid that runs and spreads out... I could be wrong...


How much of the earths water is fresh water and how much is for drinking?

3% is fresh, but 1% is for drinking.

Why is only 50 percent of the solar energy that reaches the outer atmosphere absorbed by Earths surface?

The Earth looks bright - thus much of the light reaching Earth is reflected back into space.


How much of earths oceans cover earths surface?

70% or 80% of water covers the earths surface


What does the absorption of thermal energy from the ground do to earths surface?

The absorption of thermal energy from the ground heats the lower atmosphere and keeps Earth's surface much warmer than it would if there were no atmosphere. :)


What prevents all of the sun energy from getting to earth surface?

Much of it is absorbed by the atmosphere. The ozone layer absorbs a lot of it.


How much is absorbed by the Earth's surface?

How much of earths surface does not have water on it?

about 30%


What influences the amount of solar energy absorbed at the earths surface?

There are many factors associated with the absorption of solar energy based primarily on the wavelength or nature of the solar energy under consideration. For example, neutrinos are mostly not absorbed at all. "Albedo" is used to express how much incident radiation from the Sun is reflected or absorbed, and the albedo changes for different wavelengths of light (electromagnetic radiation); it is a specific term of "reflectivity." In turn, albedo is determined by the cloud cover, terrestrial terrain, composition of the atmosphere etc. Longwave (red-shift) radiation absorption may be very different than UV (shortwave), and some wavelenghts may "bounce" completely, and very little of the incident radiation may be absorbed on the Earth's surface.


How much more is Earths surface of gravity than the Moon's?

Earths surface of gravity is 4.6m/s2 more than moons.


Does radiant energy produce heat energy when it strikes matter?

To the extent to which the energy is absorbed, yes. Reflectivity and color determine how much energy is absorbed, but no matter can reflect 100% of the energy striking it. Some will be absorbed by the molecules.


How much of the earths surface is covered in garbage?

28 %


Where is the earths energy released?

Earths energy is released when there is too much heat inside of Earth and volcano's erupt.


Which is hotter the sun or the earths crust?

The Suns surface is about 6,000K much hotter than the Earths crust. The hottest lava can get at the surface is about 1,400K
