manufacturing and operation are dependent on the electricity mix
used for the latter.
The carbon footprint related to watching a movie using P2P
could be lowered through higher uplink bandwidth or through
decreased movie size. Production of end-use devices, especially
TVs, is a main contributor to the environmental impact of a system
and therefore it is essential that such equipment be utilised efficiently.
For example, a longer life time of the TV would decrease the
climate change impact considerably.
