Prices are averages reported to the U.S. Energy Information Administration and the Bureau of Labor Statistics, not quotes from a specific station or utility. Your price depends on your provider, rate plan and usage. Power plant, utility and charging station details come from EIA, EPA and the Department of Energy and can lag behind changes on the ground.
