Academic science, research and technology companies are currently working intensively on the possibilities of using cutting-edge information and communication technologies in practice. An example of the much-needed deployment of unmanned aerial vehicles (UAVs) is energy. This sector of the national economy requires the monitoring of large line and area objects at regular intervals in order to analyse the state of wear and damage of energy equipment. The Slovak Republic, as a modern European country, is working very intensively on the implementation of all available modern technologies in the energy sector. The text of the chapter aims to present and describe the current state of practical use of drones in the energy infrastructure in Slovakia.
