Current status and the future of the energy intensity and efficiency of various energy sources are considered and analyzed. Considerations of the Rosenfeld effect, the “energy cliff” and EROI are included. The energy efficiency ratio (EER), the coefficient of performance (COP) as the equivalent measure using SI units, and the ‘equivalent COP’ are also considered. Energy use per unit of PPT GDP (or general economic intensity of GDP) of selected countries in 2018 is shown, with GDP of the UK and Italy being (according to the Word Bank; expressed in kg of oil equivalent per US$), nowadays, the most energy intensive. The author uses methods of comparative and systematic analyses, which are implemented for assessing the energy intensity and efficiency  globally, in the USA, UK, and Germany. Also, investments in the global and German energy sectors are considered. The paper mainly concludes that the global energy intensity tends to decrease in real terms since the beginning of the 70s while energy efficiency also decreases as non-conventional fuels are more actively developed.
