SaveOnEnergy has been in business since 2003 and specializes in the Texas energy market. Because Texas has a deregulated electricity market, there may be dozens of providers to choose from in your area.  SaveOnEnergy.com doesn’t list every energy provider in Texas, and some providers may operate in other states, too. But most of the information they provide is aimed at residents who live in areas covered by the Texas power grid.  Searches for ZIP codes outside of Texas will redirect you to ChooseEnergy.com, a similar comparison site that covers other deregulated markets.
