The energy comes from "nuclear fusion". Stars like the Sun create helium from hydrogen by this method, and that gives out energy. That's how the Sun creates energy.

That is approximately the case; it would be more accurate to say that the energy content of the visible light of the sun is (in part) later radiated into space at night in the form of infrared radiation. Of course, not all of the energy is radiated into space, since some of it does other things such as driving photosynthesis or causing the evaporation of water.
Solar energy that heats the surface is re-radiated as infrared radiation, some of which is absorbed by the atmosphere in the process. Water vapor, methane, and carbon dioxide can all collect this re-radiated energy to some extent.
I don't think there is any energy associated with empty space.
The other stars are so distant that most energy is lost to space. Radiated energy uses the "inverse square" law- 2 x as far= 1/4 as much, 4 times as far = 1/16th as much, etc. 10 times as far=1/100th as much. The other stars are MILLIONS of times further away than the sun.

According to scientists, the balance between incoming solar energy and outgoing energy radiated into space is considered the earth energy budget.

It's lost to space

It will be radiated into outer space.
That is approximately the case; it would be more accurate to say that the energy content of the visible light of the sun is (in part) later radiated into space at night in the form of infrared radiation. Of course, not all of the energy is radiated into space, since some of it does other things such as driving photosynthesis or causing the evaporation of water.
It heats up the environment. Eventually, it will be radiated out into space.
It is radiated electromagnetic energy, the only sort that can travel through space.
This absorbed energy is then re-radiated as heat
Of course not. Energy is radiated out all the time. The hotter an object, the more energy will radiate away.
