In this course, we pay attention to the different turbomachinery, alone or in association, used for energy production right now or in the near future. The available resources are analysed and are discussed dependent on the type, on the geometry and on the main dimensions of the different turbomachinery and their operating modes.A part of the electricity produced with turbomachinery came from direct extraction of the energies of the wind (wind turbines), from the rivers or from the water head (hydraulic turbines). The last part of the production came from an association of different turbomachinery (compressor, turbine and heat source), often called gas turbines or steam turbines. These systems producing both heat and mechanical power (converted to electricity power)
