That's not the context that everyone else is referring to. They are referring to this: "[NERD NOTE: A terawatt is a trillion watts. The entire planet’s electrical consumption is right around 5 terawatt-hours. One TWh (terawatt-hour) is a constant flow of a trillion watts of electricity for a period of one hour.]" The argument others are making (which I think is correct) is that it is meaningless to say "The entire planet’s electrical consumption is right around 5 terawatt-hours" without specifying a time frame over which that consumption occurs.
