4% is enough to power NY every year. This is a lame article, with some big TV envy going on. Where's the wattage information? The average large screen will increase your electric bill $3 per month, but you could save that by turning off a light while you use it.
That's exactly it. And I'd bet that the 4% is from homes where the TV is left on throughout the whole day. TVs may be big but they really don't use that much electricity. I could be wrong but I'd guess hairdryers and toasters use more power in the few minutes per day that they are used than a tv does all day.
