Energy () is one of the resources you can use in It Girl. It is used for shopping and flirting. It is also used in Las Vegas for gambling at the casino. With it you can even tan while on the Cruise. It regenerates over time, but can also be refilled with power-ups that can either be sent to you (Mini Candy Bar), bought with Facebook Credits, or given as a gift from your Boyfriend.
A player can increase their energy level with energy boosters (candy bar, hot cocoa and a variety of other boosters). Boosters can also be sold for It Girl cash. To see the list of known Energy boosters, click H E R E .
