Do the traditional pleats in curtains serve any useful purpose?

Curtains are traditionally made about 50% wider than the window opening, so they are thrown into folds or pleats. My friend says this is necessary to obtain optimum heat insulation. I say that the folds will just provide more surface area for air and heat to pass through. Who is right? What is the optimum configuration for a set of curtains?
