100% of the energy entering earthâs atmosphere comes from the sun. ~50% of the incoming energy is absorbed by the earthâs surface i.e. the land and oceans. ~30% is directly reflected back to space by clouds, the earthâs surface and different gases and particles in the atmosphere (the earth's albedo is 0.3 on average). ~20% is absorbed by the atmosphere and clouds. The 70% of the sunâs energy that is absorbed by the earthâs surface, clouds, and atmosphere causes warming. Any object or gas that has a temperature emits radiation outward, and this is ultimately re-radiated back into space.
Only a small portion of the energy radiated by the sun into space strikes the Earth, one part in two billion. Yet this amount of energy is enormous. The sun provides more energy in an hour than the United States can use in a year! About 30 percent of the radiant energy that reaches the Earth is reflected back into space. About half of the radiant energy is absorbed by land and oceans.
