Electricity Prices are More Stable than Gasoline Prices

All energy prices vary from month to month and year to year. However, when comparing the national average retail price for a gallon of regular gasoline and a kilowatt-hour (kWh) for residential electricity, the pricing for gasoline is far more volatile. In the two year period shown in the figure below, electricity prices varied by approximately 11% from 11.06 cents to 12.33 cents per kWh. For the same period, gasoline prices varied by approximately 40% from $2.80 to $3.91 dollars per gallon.
