Are the supportive policies adjusted in view of progress? This is all the more important given that renewable technologies have shown a high learning rate. During 2011, prices of PV modules dropped by another 45%, reaching USD 0.90/W installed at the start of 2012 (BNEF, 2012).20 Overall, this amounts to a 75% drop in prices since 2008 (UNEP FI, 2012). On the one hand, lower cost of production for clean technologies is an opportunity to increase the ambition of the overall long-term clean energy objectives.
