Why do accelerating electrons not emit electromagnetic radiation? I've read at many places that accelerating charged particles emit electromagnetic radiation, but on this article on Bohr's hydrogen atom, at the end part, it's written under Limitations of the Bohr Model that:

The Bohr Model does not account for the fact that accelerating electrons do not emit electromagnetic radiation.

I'm getting confused, can anybody explain this?
 A: It is a misfortunate (and possibly ungrammatical) phrasing. Under the headline Limitations of the Bohr model the linked article states that.

The Bohr Model does not account for the fact that accelerating electrons do not emit electromagnetic radiation.

What is meant is that electrons rotating around an atomic nucleus are accelerated, and therefore must radiate and lose their energy. However under the Bohr model they do not emit any radiation. Thus, this is a shortcoming of this model.
A: The Bohr model was invented so as to explain the spectrum of light from the Hydrogen atom,. By classical theory the spectrum should be a continuous radiation  and the electron should fall on the proton and neutralize it, thus no atoms. With his quantization of angular momentum postulate the model reproduces the spectrum, and the energy levels seen.
The free electrons when accelerated radiate.
It is one of the set of data   that necessitated the theory of  quantum mechanics , together with the black body radiation and the photoelectric effect.
