A huge amount of electricity is wasted in non-cloud datacenter deployments which service limited geographies (time zones). For example, the US stock market is open from 4 AM to 8 PM, leaving one third of the day with literally no trading activity. Do you think the servers involved in this market sleep? They mostly do not, and moreover they typically have all power management disabled, including dynamic underclocking (Intel SpeedStep). Figure 200-300W per server and maybe 100K machines (not including desktops which also suffer most of this, but at least consume fewer watts). I guess that's at least 10 MW wasted, or about five wind turbines worth, just for the US stock market.

(The average wind turbine capacity factor in the Texas Panhandle is closer to 35% because it's windier there)
