At the International Conference for Renewable Energies in Bonn in 2004 Spain and Germany decided on an exchange of experience regarding their provisions for feed-in fees for electricity from renewable energies (International Feed-In Cooperation). This also aims to further optimise this successful model for increasing the use of renewable energies in the electricity sector, to raise greater awareness of its effectiveness and efficiency and to support other countries in optimising their provisions.
