Energy security is not only an economic category. Energy sources are often used as a means for accomplishing foreign policy goals. Therefore, energy security is also an important political issue which is strongly intertwined with the protection of national interests. The Republic of Croatia has the geo-political preconditions for regional and European positioning and can capitalize on its geographic position by increasing energy security and by becoming a major energy hub.

Every country strives to achieve a satisfactory level of energy security that would enable it to maintain regular supply at affordable prices. In their attempts to avoid dependence on a single source of energy or a single supplier, countries engage in attempts to diversify sources and routs of energy supply.

Such dependence on a single source of energy or a single supplier renders countries vulnerable to disruptions in supply chains. These disruptions might be caused by problems with infrastructure or accidents, but they might also be the result of deliberate activities stemming from particular political, security or economic motives. Monopolistic energy suppliers may take advantage of their monopoly and extract political and economic concessions from countries where they hold such positions.
