How much is that cup of coffee? The answer depends not just on the price of the beans, but the electricity used to brew them and keep the pot warm. In Denmark, for example, running a drip coffee maker every day costs nearly $60 a year; in the United States, about a third as much.

The difference from country to country stands out in the graphic above, which shows average annual electricity costs for a coffee maker, television, and refrigerator. It's worth noting, though, that the numbers must be taken in context: Mexico's electricity prices rank as the cheapest among countries listed in a recent International Energy Agency report, but its median household income is less than one-sixth that of the United States.
