One of the important dimensions of the evaluation of society existence is energy security. Providing the right framework for the electricity sector is the basis for the operation of this type of security in its economic dimension, and so this issue can be seen as one of the top priorities of energy policies. This raises the need for an appropriate legal framework to enable proper interaction of administration bodies responsible for the overall relations, both inside and outside the state. Associated with this is also the issue of the appropriate rank of the fundamental – constitutional – norms. The Polish example of a system of constitutional law shows that, despite the lack of a reference to this issue in the Constitution, by means of interpretation of “sustainable development” (art. 5 of the Constitution of the Republic of Poland) one can find the relevant legislation, allowing the chief state authorities to carry out the activity in relation to the issue of “energy security”.
