where:
Production¼ Production, distribution and end-of-life data for the
LCDTV (Fraunhofer Institute for Reliability and Microintegration,
2007a)
Life length ¼ 5 years
Active use time ¼ 5.5 h/day (the average time for watching TV in
a two-person household in Sweden (Zimmerman, 2009)
Electricity in active mode ¼ 150WElectricity in stand-by ¼2W
1 h part of standby ¼ 1.35 (7.44 h in standby/5.5 h in on mode
(Zimmerman, 2009))
The figures obtained from this calculation were then multiplied
by the use time of the system (2 h for both IPTV and P2P
systems).
