A cute animated firefly flying through a city at night.

The ad opens with a cute, animated firefly character flying through a nighttime cityscape. The firefly then enters a house through a window, revealing a family inside. The first scene shows a man cooking in the kitchen, and the firefly zips around him. The next scene shows a couple relaxing in the living room, watching TV, with the firefly dancing nearby. The final scenes show the exterior of the houses with wind turbines visible in the background, and the Green Mountain Energy logo and tagline appear. The animation is bright and cheerful, with a focus on the firefly's playful movements.
