Newtonian point of view: As the universe gets bigger, there is more energy from dark energy. However, as the universe gets bigger, PdV work is done on it by sources of pressure. Since dark energy has a negative pressure, this work is negative, and so the two energies exactly cancel out to conserve energy.

Thanks for clarifying that up for me, I really appreciate it. I'm interesting that tensor equation you showed me. I'm not really familiar with tensors, I do know partial derivatives though can you explain that equation more throughly for me.
