Environmental/Economical benefits of not transmitting parts of a video?

Are there any potential environmental och economical benefits (in terms of infrastructure) derived from not transmitting video packets unless absolutely necessary or requested by the client for Media-Streaming services?

Skipping parts of the video: Lets say video quality isn´t an issue, and video packets are sent just in time. Segments that could remain unsent include: commercials, intro, outro, etc.

I´m thinking most of the energy consumption used is passive, that is, used to just keep the lights on. But some part must be active, when the individual video packets are transmitted.
