In Work package 1, benefits of technological change and the security of supply which have not yet been quantified are examined in more detail. First, relevant positive effects of RE deployment on technological change in the field of RE technologies are identified, with the focus on the dynamics of innovations and technology costs. Second, the security of supply is examined in a system with and without RE.
The focus in Work package 2 is on the identification of the distributional effects of energy and environmental policy measures, the microeconomic cost burdens and cost reductions of different actors differentiated by structural criteria like economic sector, income group, household type and region. First, an overview on methodological foundations as well as on the main distributional effects of RE deployment is given. The analysed measures include market support policies in the power sector, RE expansion in the heat sector, RE use in transport, funds for research and development (R&D) and for market development, electricity price effects, taxation and grid expansion.
Work package 3 tackles the analysis of technical, economic and instrumental interactions using the examples of RE expansion and electric mobility. In particular, possible synergies in the power sector are examined quantitatively and qualitatively.
In Work package 4, the macroeconomic gross and net effects on employment and growth are determined, including the distributional effects of RE expansion. The effects are shown differentiated by socioeconomic, sectoral and regional criteria.
In Work package 5, the costs and benefits of expanding renewable energies are shown for the three categories of effects: system-related, distributional and macroeconomic as well as further developing the methods used to estimate these effects where required.
