The accelerated development of RES requires anticipating investments in infrastructure, in particular for the adaptation and the extension of the electrical grid. On the one hand, this will encourage innovation and the development of more advanced technologies in particular because the government will reinforce support to energy research, and thus this may create a “first mover” advantage for Germany. On the other hand, as the technological progress may take time to appear and to adapt to specific needs, anticipating investment also risks deterring the use of more advanced and more efficient technologies (IEA, 2007).
