Energy security in the context of the energy transition

The article analyses the content of the term of energy security from the point of view of assessing the state of the environment and the energy transition to broad use of renewable energy sources (RES). The vast majority of world energy production still comes from fossil fuels, and energy policy of each state requires a deep understanding of the interconnection of complex issues, such as the continued demand for traditional hydrocarbon resources, the environmental problems caused by their consumption and the need for the transition to green economy. The author argues that the energy transition significantly affects the transformation of the content of energy security.
