This lecture covers the basics of Plasma Physics and Fusion Energy, starting with the distribution of energy consumption worldwide and the urgency of developing alternative energy sources. It then delves into examples from Germany, the concept of fusion versus fission, and the large energies required for fusion reactions. The lecture further explores fusion reactions, tritium breeding, advantages of fusion energy, plasma confinement methods, and the challenges faced in tokamak physics. It concludes with achievements in magnetic fusion, an overview of the ITER project, and the roadmap towards fusion energy, emphasizing the importance of innovation and research. The EPFL Swiss Plasma Center is highlighted as a key player in this field.
