double slit experiment - why do peaks the representing the interference pattern become sharper when increasing the number of light sources?



My question is related to young's theorem and the double slit experiment.


The more light sources we add the sharper the peaks of the interference pattern become. However when we add more light sources, more energy is being radiated. So my question is if the peaks become sharper where does all this extra energy go?
