Hello,

Suppose I have a charge at rest, my question is, since the electric field of this charge will "go" to infinity for eternity, where does the energy come from to maintain that field.

We all know that the charge value and the field "strength" are time independent, and since the field propagates at finite speed, we must be loosing energy to fill the yet unfilled space with this field.

Thank you in advance
