Regional Variation in Gasoline and Electricity Prices in the United States
Less often discussed is the fact that electricity prices in the United States vary vastly more than do gasoline prices. Here, political correlations are weak to non-existent, while variation within some states is profound. Price differentials here are partly rooted in the source of electrical power. Low prices in Washington state in the northwest, for example, reflect the cheap and renewable power generated by massive dams on the Columbia River.
Electricity price differences across Texas are especially notable, a topic that would merit further exploration.
