The regional, national and global primary power supply in the future will not get along without a big share of renewable energies, besides any ecological or climatical problems. The biggest potential (in theory) as well as the biggest usable potential of the renewable energies have solar radiation and kinetic energy of the atmosphere (that is wind energy). Thus the focus of the renewable energy specialization will be the theoretical basics of converting these energies and respective limits, as well as the discussion of physical and technological concepts of mode of operation, limits and applications.
