Sims with the Social Powered Trait will steadily regen Energy Need while socializing with other Sims.
This includes both "chatting," where you can see them in a conversation and rabbit hole "careers," if a socializing option is picked (like "Socialize with Coworkers").
I realize this isn't exactly a realism trait (if you socialize enough, you'll never have to sleep!), but then, most of the "Reward Store" traits are kind of overpowered. It was inspired by the idea in personality that some people are "energized" by socializing with others.
