The energy of a vacuum isn't zero. When you place conducting plates in it, there are electromagnetic modes that are excluded from the space between them, you reduce the vacuum energy in that space. The difference in energy manifests itself as a force pushing the plates together.

You Mean electromagnetic modes from the space between them?

 

Impossible much.

 

Only Matter can produce energy in any form like you said 'electromagnetic force' else impossible for vacuum to actually have energy.

 

Please correct me if i am wrong. I dont understand where the energy come from in vacuum?

If you solve the "particle in a box" you find that the electromagnetic modes have an energy of (n+1/2)*hbar*w. Even when n=0 (i.e. no photons) there is energy. This has been experimentally observed, i.e. you are wrong.
