1. Risk

2. Social Acceptance 3. Cost

–  Profitability of shale gas? –  Environmental impacts? –  Water? –  Energy pay-back? –  Carbon price?

1.  Three challenges to extending the energy status quo 2.  Renewable energy: A case of disruptive innovation 3.  Integration of a high share of renewables in the electricity

market: issues and solutions 4.  Conclusions

37 Conclusion –  The world is at a crossroads – we are facing the transition from

non-renewable to renewable energy supply. –  Risk, social acceptance and cost are three important challenges to

extrapolating the energy status quo –  With countervailing cost trends and increasing internalization of

external cost, “grid parity” has started to transform markets – renewable energy is a case of disruptive innovation.

–  Experience in Germany shows that solar and wind are profoundly transforming the electricity market, with expected and unexpected effects. This has resulted in a creative destruction of established business models, and opened up opportunities for new players.

–  Building up a balanced portfolio of renewables allows to diversify key risks of current energy supply.
