How does this generate EMFs?

How do you ground a light?  Some of my lamps have no metal which isn't 
carrying current, what am I supposed to ground?  What does grounding do 
anyway?

Why not use a wind up clock?

You think there is much shielding afforded by walls?

How does turning on the light re-energize the circuit?  Why not put the 
demand switch back at the panel?  How much EMF given off by the remote 
key fob?

Thank You Kindly,
