> The five-mile stretch of energy-saving street lights saves 2,100 kWH per week, which would amount to approximately 21 hours of ironing, or four hours of watching TV on a plasma screen.
Irons are rated at around 1 kW (and that's not continuous for all irons I've used). 21 hours of ironing is therefore 21 kWh max, probably a whole lot less (1/10 doesn't sound wrong). Plasma TVs (depending on size) use a couple hundred W.
It kind of seems like the article author is confusing "." and ",", so they were perhaps thinking the street lights saved 2100 Wh (which definitely doesn't sound right on a per-week basis). (In some European countries they use , for the decimal separator.)

Yeah, its an article about Norway, by a Norwegian, in the Daily Scandinavian, an outlet whose name is a pretty big clue as to its focus, and of which the aforementioned Norwegian is editor-in-chief. What do you expect it to use for the decimal separator?
