<<With each Web device draining as much as a megawatt-hour a year>>

I thought this estimate seemed high but look at this data. bethel.edu for the Macintosh 6500/250 shown on the plot towards the bottom of the page. They calculated 19.872 megawatt-hours per year for 23 computers or 864 kilawatt-hours for 1 computer. Assuming as Gilder did a billion always on internet computers (I did not check this estimate) would consume (864)(10^9)= 0.864 trillion KWHR's. Today the total world energy demand has been estimated at around 13 trillion KWHR's = 13(10^12) KWHR. eia.doe.gov. Therefore computer use would require (0.864/13)= 6.6% of the worlds projected energy demand in 2000. Still a big number although Gilder projects on Internet computers--together with the factories that build them would close to half of the world's current electricity use. Amazing stuff.
