Energy sources<\/strong> have always played a very important role in the development of human society. Since the industrial revolution, energy has been a driving force for modern civilization development. Technological development and consumption of primary energy and<\/strong> the increase of the world population are interdependent. In the past 20 years, the world around us has changed significantly. Technology has become one of the main drivers of economic and social development. The rapid advancement of Information Technology (IT) worldwide has transformed the way we think and the way we act. It must be noted that practically all technologies run on electrical energy<\/strong>. Therefore,\u00a0the share of electricity is increasing rapidly, faster than Total Primary Energy Supply<\/strong> (TPES – \u00a0the sum of production and imports subtracting exports and storage changes.).<\/p>\n

At present, fossil fuel is still the world\u2019s predominant energy source. Its extraction, production, and use are not considered efficient regardless of the new technologies available to improve its use and extraction. When studying energy resources, we have to distinguish the primary energy sources<\/strong> and secondary energy sources<\/strong>.<\/p>\n

Primary energy (PE)<\/strong> is an energy resource found in nature that has not been subjected to any conversion or transformation process. It is the energy contained in raw fuels<\/strong> and other forms of energy received as input to a system. Primary energy sources take many forms, including nuclear energy, fossil energy — like oil, coal, and natural gas — and renewable sources like wind, solar, geothermal, and hydropower. These primary sources can be converted<\/strong> to secondary energy sources, so-called energy carriers<\/strong>. Primary energy sources can be divided into:<\/p>\n
