Expenditures on energy, particular electricity, are a necessity for most homeowners. In the City of Wilson, North Carolina, residential customers spend an average of approximately $146 each month on electricity. This equates to an annual electricity expenditure of roughly 4.8 percent of the City’s Median Household Income of $36,469, higher than the nation’s average of 2.7%. In order to assist the City of Wilson’s Utility Department in gaining a deeper understanding into their residential customers’ electric and gas usage and expenditures, the Environmental Finance Center at the University of North Carolina at Chapel Hill (EFC) used the City’s utility billing data, as well as tax parcel data from Wilson County, to analyze the utility’s residential electricity and gas accounts by usage and expenditure characteristics.
