@dalias @karppinen just look at the router at home. It maybe condumes 11,5 W base load and when you download 2 GB over 1 hour it increases to 11,6 W. So if you don't turn it off, the 11,5W are used anyway. The 2 GB caused maybe 0,1 W extra electricity. I don't think that it's much different in internet routers (except them having more throughput). The big factor with Netflix is your screen. A Projector causes more emissions than a TV > computer monitor > laptop > smartphone.
