We know that accelerated charges radiate energy in form of electromagnetic radiations. Since acceleration is frame dependent, is the radiated energy also frame dependent? Is that why energy radiated is different in different frames?

Acceleration is the same in all inertial reference frames, so all inertial observers agree on the energy radiated by an accelerating charge.

    That’s complicated. Here is a related question: https://physics.stackexchange.com/questions/21830/does-a-charged-particle-accelerating-in-a-gravitational-field-radiate – G. Smith Feb 03 '19 at 18:18
