Energy security is not a modern concern and is a common and strategic issue for every economy in the world. It consists of complex tasks with variety of solution targets, which can be based on short- and long-term conceptual approaches. On the other hand, nowadays the problem has significant differences among various countries and regions and can change its content even in a short term period. The paper begins with alternative concepts of energy security and concludes with personal conceptual view of the author to the problem and its solution. Dependencies between energy security and various other factors are analyzed. Based on the conclusions, the paper finally proposes an optimal conceptual control model for energy security for efficiency and sustainability. As a result, an “open energy” concept is offered for achieving a near-perfect energy security.
