Question

What is energy input and output on earth?

Answer 1

These are approximations but from NASA,
340 `W`/`m^2` is received by Earth 100 `W`/`m^2` is reflected by the clouds and ground collectively so about 240 `W`/`m^2` is absorbed into either the ground or the atmosphere.

The Earth emits around 400 `W`/`m^2`, to which 340 `W`/`m^2` is reflected back through greenhouse gases, the rest escaped through radiation. The clouds emit around 30 `W`/`m^2`, the atmosphere emits around 170 `W`/`m^2` and there is an atmospheric window which emits 40 `W`/`m^2`.

These figures were generated using average over a ten year period.

Hope this is useful.
