If you choose to pay with Energy, Begin a Dance of Decades lets you pay any amount of Energy – even more than the amount you'd normally have to pay. This may be advantageous if you want reduce the time it will spend impending. The impending card will then come into play on a future turn, like impending cards normally do. It won't automatically gain all elemental thresholds on that future turn, and it won't have an energy discount, since those effects of Unlock the Gates of Deepest Power expire when Time Passes this turn.

Do Dances Up Earthquakes' Impending Power Cards count as being in hand, play, or discard?
No, impending cards are set aside out of play until they accumulate enough Energy to be played. They can't be played (except by Rhythmic Powers Builds to a Cataclysmic Crescendo), can't be discarded, and can't be reclaimed. They also don't count as being in play for, e.g., Earth Shudders, Buildings Fall or Gift of Seismic Energy.
