I am new to it, so please help. As I know, AC current is back and forth motion of electrons, which radiates electromagnetic waves, so there is energy radiation from power line to our home. But in case of DC, if the magnetic field and electric field are static then how does energy radiate. I have searched that drift velocity of electron is slow, so DC flows at the same speed as of AC which is C. So, how does this happen if there is no radiation of DC? Please answer.

Electrons encounter a resistance as they flow through a wire. The energy used to overcome that resistance $(E=I^2R)$ is converted into heat, which is radiated in electromagnetic (infrared) radiation.
