That's the big charge regularization problem, officially still unresolved, requiring deformation of standard EM energy density.

No you don't have to integrate energy density to get total energy. I already have total energy mc^2 without integrating. We have resolved the regularization problem. It's simple. You don't have to regularize. The electron is cut off at a finite length near Planck length. No more regularization, no more renormalization is required!!!!
