Work package 1: Benefits of RE expansion

Technological change

The term “Technological change” covers the phase of innovation on the one hand, in other words, applied research and development as well as the early commercial application of new technologies or processes. On the other hand, it also describes the phase of diffusion during which clear advances to a technology can be observed with regard to cost reductions and efficiency or quality improvements (“learning by doing”). 

In this project, an assessment is made of how promoting RE expansion influences the technological change of RE technologies. The primary question here is how to quantitatively estimate the influence of policy measures on technological change. The analysis focuses on innovation effects in the fields of photovoltaics, biofuels and wind energy by observing the dynamics in patent applications, public R&D spending and exports. In addition, the cost development of these technologies is presented for biofuels in detail including the learning effects.
