In recent years, governments in East Asia1 have seized the opportunities of foreign capital inflow in the renewable energy market and have taken policy measures to stimulate investment in renewable energy. According to a report by Greenpeace Japan, there will be renewable energy investment opportunities worth 205 billion U.S. dollars in Southeast Asia over the next decade. However, as green energy supply increases, many multinational companies and manufacturers have publicly pledged to achieve 100 % renewable energy by a certain year and further required supply chains to go green. In East Asia, the center of original equipment manufacturing, demand for green energy becomes increasingly urgent, while the current renewable energy market is significantly in short supply. Against these backdrops, is it possible for such a market situation to turn around by 2030?
