The government can design the energy future in two ways: Either by a defining energy plants and their organisation in a concrete manner and dictating the measures and regulations accordingly, or, by setting an abstract aim such as reduction of emissions without spelling out the necessary measures. The first model I should like to call the 'regulation model' the second as 'deregulation model'. The difference in method and performance of both models is comparable to the difference between a socialist planned economy and a social market economy. (orig.).
