As the map and table indicate, many homes and businesses in the US are still operating within regulated energy markets. In regulated markets there is no competition — you pay your local utility directly for the electric/gas they provide you, whatever that (high) cost may be.
Deregulated Natural Gas Markets
As of 2025, nearly half of US states have introduced some degree of energy deregulation and retail energy choice to homes and businesses within their borders.
Approximately two dozen states — states like Georgia, Massachusetts, and Illinois — operate a deregulated natural gas market. As is the case with electricity, deregulated natural gas markets are where the buying/selling of natural gas is not monopolized and controlled by a single utility. Instead, suppliers are allowed to enter the market to create competition and and hopefully lower the cost of natural gas rates for homes and businesses in that area.
