Energy consumption is the most important indicator of a country's economic activities. The
changes in primary energy consumption can be analysed as an indicator of the temporal variation of the
economic activities of the countries. In this study, statistical analysis of Global primary energy
consumption and the primary energy consumption of Turkey, Italy, USA, Brazil, Egypt, Saudi Arabia,
China and South Korea were performed. In the selection of the countries to be analysed, the development
level, geographical locations of the countries, diversity and comparability were considered. The longterm trends of change of primary energy consumption data between 1966-2021 were analysed empirically
using Innovative Trend Analysis (ITA), Mann Kendall (MK) and Sen's slope prediction tests. The annual
data of the total primary energy consumption of the countries were used in the analyses. Analysis results
and graphics were examined and it has been determined that there is a statistically significant and
increasing trend (p<0.05) for primary energy consumption in all countries and globally. The results
obtained were also supported by the Innovative Trend Analysis results. In addition, a strong correlation
(r2
=0.998) was found between slopes of ITA and Sen's slope estimator. As a result, because of the increase
in population, industry and people's welfare and technological developments it is predicted that the
primary energy consumption of countries will increase in future.
