I learnt that when we accelerate a charge we get EM radiation. If I have a universe with only 1 electron in it so that no other Electric Field exists, and I then procced to accelerate the charge, will I still get EM waves? (Neglecting mass of charge) Since there is no other force on this charge, because the Electric field cannot act on iteself, I need no external force to accelerate it. Therefore i can keep producing energy in form of em waves. If yes, then is the energy conservation not violated?
