I don't know where you live, so it's impossible to say what you actually mean. But if you are referring to the choices for electric power, these are almost certainly new developments that have been forced by legislation mandating giving consumers a choice, which is only a small walkback of the past century of promotion and even subsidizing energy producers that use fossil fuels. Energy production is a deeply non-free market. Even in recent times with the rise of solar, it's often the case where it's illegal (or sometimes merely inconvenient or uneconomical) to sell power back to the grid.
