By now, the German regime has undergone multiple stages of development. In its earliest stages in the 1990s, however, the German FiT had relatively little impact on the overall mix of electricity production. This changed with the introduction of the Renewable Energy Sources Act(“EEG”) of 2000. Three main phases of the EEG history can be identified (see also table below): 22 22 Fulton et al.(2012), pp. 1 sqq. 11
