" [L] Electromagnetic Jam (10) Flip a coin. If heads, your opponent can't attach any Energy cards from his or her hand to the Active Pokemon during his or her next turn."

Where does the effect lay? On the opponent or on the defending pokemon?

The effect is on "the active Pokémon" -- in this context the defending Pokémon. Here's the analogous attack:

== FREEZE LOCK (Dewgong - Skyridge Expansion)

Q. Skyridge Dewgong "Freeze Lock": the card text says "flip a coin, if heads your opponent can't attach energy cards from his or her hand to his or her active pokemon during his or her next turn". If the active pokemon retreats, does the effect wear off?
A. Yes, it does. (May 15, 2003 WotC Chat, Q1577)

So, if it can remove the effect (retreating, evolving, etc.) energy cards may be played.
