Does the Earth accumulate the energy it receives from the Sun, or does it reflect all of it back into space?

Question

I understand that the sun gives energy primarily in the form of sunlight, which contains various wavelengths of electromagnetic radiation. If the earth absorbs some of the energy, does the earth’s “total energy” accumulate?

Answer 1

The planet (on average) emits the same amount of energy it takes in, otherwise, it would eventually burn up or freeze over.

The Earth receives low entropy (concentrated) energy from the sun, and emits high entropy (dispersed) energy back into space as infrared.
