A surface with high albedo reflects a large percentage of light. A snow field has high albedo. Most of the energy that reaches the Earth''s surface comes from the Sun Heat at Earth''s Surface. About half of the solar radiation that strikes the top of the atmosphere is filtered out before it reaches the ground. This energy can be

Solar Energy, Albedo, and the Polar Regions

Once the sun''s energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun''s energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun''s energy is reflected back to

The Sun''s Energy: An Essential Part of the Earth System

This energy travels about 150 million kilometers (93 million miles) through space to reach the top of Earth''s atmosphere. Waves of solar energy radiate, or spread out, from the Sun and travel at the speed of light through the vacuum of space as electromagnetic radiation. By the time the Sun''s energy reaches Earth''s surface, it has a

Approximately What Percentage of Solar Energy Is Lost Before

Solar energy is dispersed and lost before it even reaches the Earth''s surface, mainly due to factors like reflection back into space.Approximately 30% of solar energy is reflected back, preventing it from being absorbed by the Earth. This loss through reflection is a significant component of the Earth''s energy budget and plays a vital role in climate regulation.

Earth''s energy budget

This energy plays no role in Earth''s climate system. 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.
