The German Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz
EEG) promotes the generation of electricity from renewable energy
sources by a feedin tariff scheme. In general, renewables are considered
to be environment-friendly with respect to climate change and other
environmental harm associated with fossil-nuclear energy provision. In
fact, renewables themselves cause new environmental costs regarding
space requirements, related land-use conflicts and the need for scarce
raw materials. Therefore, support policies should not only take into
account economic but also ecological criteria. The objective of this
study is to assess whether or not environmental criteria are reflected
in the German photovoltaic support scheme stipulated by the EEG. It
thereby aims to establish a connection between the economic investment
stimulus of renewable electricity support schemes and the environmental
performance of their supported technologies taking photovoltaic as an
example.
