Energy counters are a kind of counter that a player may have. They're not associated with any specific permanents.

energy is the energy symbol. It represents one energy counter.

Keep track of how many energy counters each player has. Potential ways to track this include writing theme down on paper or using dice, but any method that is clear and mutually agreeable is fine. (At higher levels of tournament play, dice may not be allowed for tracking counters that players have.)
