http://en.wikipedia.org/wiki/Coal#World_coal_reserves[1] Running one 100 watt computer for one year requires 876 kW·h (100 W &tim24 h/day ×365 {days in a year} = 876000 W·h = 876 kW·h). Converting this power usage into physical coal consumption: It takes 438 kg (966 pounds) of coal to power a computer for one full year. One should also take into account transmission and distribution losses[2] caused by resistance and heating in the power lines, which is in the order of5–10%, depending on distance from the power station and other factors. It also generates about 800 lbs of CO2 Moral: Turn you laptop off when you are not using it. --- Links --- 1 http://en.wikipedia.org/wiki/Coal#World_coal_reserves 2 http://en.wikipedia.org/wiki/Power_line#Losses -- Binary/unsupported file stripped by Ecartis -- -- Type: image/png -- File: 541a6f12f0b495022ce2949aea4a5057.png ---- Husker Linux Users Group mailing list To unsubscribe, send a message to huskerlug-request@xxxxxxxxxxxxx with a subject of UNSUBSCRIBE
