In 2012, Hawaii had the highest electric bills in the US, registering an average monthly bill of $203; New Mexico, on the other hand, registered the lowest bill at $74. Louisiana has the highest consumption of electricity, while Maine has the lowest. This data was released by the US Energy Information Agency (EIA), which measures the average price and consumption of residential, commercial, industrial and transportation energy. The agency says that residential consumers account for the highest number of electricity sales and generally pay the highest prices for electricity.
