With ‘Monumental Triumph’ at the Paris COP 21, the Paris Agreement for the New Climate Regime presents new opportunities for renewable energy. According to the International Energy Agency (IEA), more than $12 trillion is expected to be invested in the energy industry, and $8 trillion will be allocated to the renewable energy sector by 2030. To facilitate and coordinate energy transition around the world, collaboration among countries, as well as public and private, is inevitable to scale up the market opportunity. In that regard, Korea has embarked on 'The New Energy Industry's strategy as the core of the Creative Economy and is trying to make Jeju Island its showcase. Under the 'Green Big Bang,' Jeju will make itself a 'Carbon Free Island' by 2030 by using 100% renewable energy for electricity and 100% electric vehicles for transport, all of which will be linked to the smart grid system. What are the chances for private-public partnerships not just at the domestic but also at the global level to make Jeju Green Big Bang successful?
