About residential electricity price
What this measures: Average retail electricity price paid by residential customers, in cents per kilowatt-hour.
Why it matters: Electricity is a fixed monthly cost most households cannot easily reduce, so price differences directly affect what families have left for other spending.
Watch out: Series methodology changed before 1990. Within-state changes after 2000 are clean; older comparisons should be read carefully.
