Analysis of Primary Energy Consumption in the World in the Context of Energy Transformations

Abstract

The purpose of this article is to examine energy consumption broken down into consumption based on non-renewable sources, such as: coal, oil, natural gas and nuclear energy, and consumption based on renewable energy sources, such as: solar, wind, hydro, geothermal and biomass. The conducted research has shown that the consumption of primary energy is constantly growing, while the development of renewable energy still lags behind the pace of this growth (although its share in the total energy mix is growing year by year). The reason for this situation is mainly the fact that in many countries the economy is still based on conventional energy sources, and in some of them the consumption of primary energy is even significantly increasing (as is the case, for example, in China). For this reason, it seems reasonable to undertake various types of projects aimed at reducing the consumption of primary energy by individual countries, which, as 2019 showed, is absolutely possible.
