There are some topics discussing the carbon footprint of an email:
However, I found none about the carbon footprint of watching "IPTV": TV in streaming through a (DSL or optical fiber) box.
When you send an email, data goes to many data centers to be replicated and transmitted. Considering how many emails we daily send, this has a huge carbon footprint.
When you watch a youtube video, the data is also replicated in many data centers. Considering how many videos are hosted and watched daily, this has a huge carbon footprint.
When your Internet provider's box (like Free, Orange...) has a IPTV service, does it also have a huge carbon footprint? The data is transmitted in streaming, so I'm wondering if watching/not watching makes a real difference.
The main question I'm asking is: If you ignoring the carbon footprint of the boxe itself (power supply), does watching TV through the box have a significantly bigger footprint than watching TV through standard hertzian network (using TV tuner)?
