No concern for tomorrow. The electromagnetic spectrum is disrupted in many ways as it is emitted from the sun. We'll deal with the "fate" of all the energy eventually. For now, appreciate that very little reaches the Earth (but just enough for life), and that when it arrives produces rather inefficiently store it in glucose. Then, most of that is wasted as heat by the fourth trophic level (2nd Law of Thermodynamics)! Great question. No concern for tomorrow.
