You asked: What is total amount of solar energy received by earth and atmosphere?

How much solar energy does Earth receive?

The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses.

What is the total amount of solar energy absorbed by atmosphere?

About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.

How much energy does the Earth receive from the sun per day?

Each hour 430 quintillion Joules of energy from the sun hits the Earth.

How much energy is absorbed by the atmosphere?

In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface. The Earth radiates energy at wavelengths much longer than the Sun because it is colder.

How much of the sun’s energy do we use?

Human beings only use about a 10,000th of the amount of power the sun provides to the Earth. The people of Earth turn around 20 kg, or about 44 lbs, of mass into energy per day. At 4.5 lbs per second of solar power, we would have all the power we need for an entire day in less than 10 seconds.

What happens to solar energy if only 50 penetrates Earth’s atmosphere?

Roughly 30 percent of the total solar energy that strikes the Earth is reflected back into space by clouds, atmospheric aerosols, snow, ice, desert sand, rooftops, and even ocean surf. … The remaining 46 to 50 percent of predominately visible light penetrates the atmosphere and is taken in by the land and the oceans.
