Compared to “command and control” measures, pricing pollution provides greater incentive for innovation as it rewards for continual improvements (OECD, 201 lh). In addition, while feed-in tariffs could have had a positive impact on innovation during the creation of the RES market, this effect may decline as technologies become profitable under the current scheme. Incentives included in the system (i.e. the degression rates which encourage efficient gains) may not be sufficient to foster innovation. A broad R&D support is thus needed to develop breakthrough technologies which require basic research with long-term and uncertain payoffs.
