In the first half of the last century Romania was one of the main European primary energy producers and exporters (of oil derivatives, especially). Unfortunately, this is no longer the case.For about 30 years Romania has become a net energy resource importer, and the expectations are not optimistic.The paper presents quantitative information (data) on the primary energy resources production at the international level and by geographical zones, as well as at the national level.The conclusion that can be drawn is that traditional autochthonous primary energy resources may run-off at the life horizon of the present generation. That is why it is necessary to use energy as efficiently as possible.
