Background: Literary sources contain contradictory information about energy release. Some authors describe the trend of rapid growth of this indicator, others believe that this growth is gradually subsiding.
Objective: Authors have considered a problem of worldwide consumption of energy and its effects on economic development.
Methods: The necessary parameters were determined by data of various literary sources.
Discussion: It is shown that the direct approximation of dependencies of energy release per capita, population size and inhabited territory to calculate the energy release density is inexpedient.
It is established that the energy release density first decreases with time, and then begins to grow.
Conclusion: The main sources of growth are industrialised countries. The lack of energy leads to an increase in poverty, and therefore, to difficulties in building up intellectual capital and, as a result, to the inhibition of economic development.
