Galaxies and clusters of galaxies show remarkably tight scaling relations between their global properties. These cannot be explained by purely gravitational processes, and are instead attributed to the feedback effects of massive stars and supermassive black holes on the surrounding baryons. In this talk I will summarize how stars and black holes provide feedback. I will then outline the construction of a global inventory of the amount of energy released by massive stars and supermassive black holes over cosmic time. Finally, I will assess the impacts of these two energy sources, identifying which one is most important for the specific observed scaling relations.
