9. © OECD/IEA - 2008 Main Lessons Learnt and Conclusions

10. © OECD/IEA - 2008 Effective policies only in a limited set of countries Sometimes depending on specific technology Perceived risk, more than profit, is key to policy effectiveness & efficiency Price support can not be adequately addressed in isolation; non-economic barriers must be addressed concurrently Grid barriers Administrative barriers Social acceptance issues Other barriers (e.g. training, information, financial, etc.) Effective systems have, in practice, frequently been the most cost efficient Technology-specific support is key for both effectiveness and cost-efficiency Main Lessons Learnt (1)

11. © OECD/IEA - 2008 Main Lessons Learnt (2) Move beyond Feed-In Tariff vs. Quota Obligation System/ Tradable Green Certificate debate Both systems show success and failures depending on specific country and technology Precise design criteria and fine-tuning are key Signs of convergence: Feed-In Tariff: Premium tariff option, time digression Quota System/Tradable Green Certificate: Technology banding

12. © OECD/IEA - 2008 1. Remove non-economic barriers to improve market functioning 2. Establish predictable support framework - to attract investments 3. Set up transitional incentives decreasing over time – to foster and monitor technological innovation and move towards market competitiveness 4. Ensure specific support in function of technology maturity to exploit potential of large RET range 5. With increasing mass-scale RET penetration impact on overall energy system must be taken into account Continuity Certainty Key Principles for Effective Renewable Energy Policies

13. © OECD/IEA - 2008 Fostering REs transition towards mass market integration Niche marketsMass market Low cost-gap (e.g. wind onshore) High cost-gap (e.g. PV) Mature tech (e.g. hydro) Prototype & demo stage (e.g. 2 nd gen biofuels) Time Market Deployment Development 1. Development RD&D financing, capital cost support, investment tax credits, rebates, loan guarantees 2. Stable, low-risk, sheltered FIT, FIP, Tenders 3. Shared/imposed market risk, guaranteed minimum but declining support FIP, TGC (technology banding) 4. Technology-neutral competition TGC, Carbon trading (e.g. EU ETS)

14. © OECD/IEA - 2008 1. Realise urgency to implement effective policies to exploit major potential of RETs in terms of energy security and climate change mitigation 2. Remove and overcome non-economic barriers first 3. Exploit substantial potential for improvement of policy effectiveness and efficiency: learn from good practice 4. Focus on rigorous and coherent implementation of key policy design principles with regard to long-term cost efficiency and national circumstances 5. Create level playing field by pricing in GHG emissions and other externalities 6. Allow a combination framework of incentive schemes in function of technology maturity level Urgent action for Energy Technology Revolution Recommendations
