Investigation of usage potentials of global energy systems

Throughout history, mankind has made progress in social and technical areas by finding many energy sources and developing energy systems. For this reason, energy is a necessary and indispensable issue. Today, due to the increasing demands, the energy requirement has increased even more than in the past. In order to increase this energy capacity, researches and studies have been carried out on the use of energy systems more efficiently. They will be also carried out in the future. In the new global world, great progress has been made in the energy systems technology and very different systems have been found. It is clear that these systems provide high benefits in many sectors, especially in the industrial and transportation sectors. In order to use the energy for their internal consumption, and also export it, the developed countries have power plants with large production capacity. For this reason, the developed countries are competing with each other in energy issues. Producing mechanical and electrical energy, using underground energy sources and alternative energy sources are the major factor which keeping pace with the changing world. In this study, it has been tried to give technical and statistical information about the use of natural energy, natural gas, coal and nuclear energy sources and renewable energy systems such as wind, solar, hydro and biomass. We emphasized which energy system the world head toward for certain years. In addition, the advantages and disadvantages of these systems have been demonstrated.
