Abstract :The energy needs, which started with the history of humanity, have gained vital importance especially in parallel with the development of technology. The increasingly high amounts of energy consumption for the production and use of everyday technologies drive communities to find and develop different energy sources. Indeed, the energy supply is one of the main issues of modern society. Many solutions are proposed to solve the problem of energy supply, including the effective use of traditional resources, increasing the use of alternative sources, and diversification of energy sources. However, access to energy resources and energy generation require significant investments. Therefore, energy investments are one of the important pillars of energy supply.
