The most energy-efficient state is New York, according to a recent study, which measured the energy efficiency of continental United States.

To gauge energy efficiency,, a personal finance website, examined two key metrics: home energy efficiency and auto energy efficiency. Home energy efficiency was determined by calculating the ratio of total residential energy consumption to annual degree days. To determine auto energy efficiency, researchers measured annual miles driven per capital in a state and divided the annual vehicle miles driven by gallons of gasoline consumed.

Each calculation was weighted proportionally against national consumption patterns and graded on a 100-point scale; a 100 score is optimal energy efficiency. New York scored a 90.22, while the least-efficient state, South Carolina, scored 21.51. Alaska and Hawaii weren’t included in the study because of data limitations.

Here are the top five and bottom five states according to the study:
