Technological and tectological practice in energetics

Two design ways transformation practice are considered as an example of energetics. Hydrogen and nuclear energetics are shown asa technological practice. Hydroenergetics and energetics, based on the processes of rotting, occupy an intermediate position and are named «technologies with the elements oftectology». Solar, hidrogen, geothermal energetics and energetics based on the wind energy are shown as a tectological practice.
