Investment in renewable energy sectors in many developing countries has grown significantly in the last decade. Developing countries now seek to attract investment in the renewable energy sector. Foreign investment in developing countries hinges on factors such as security of investment, entry barriers, cost of doing business, repatriation of profits, dispute resolution, etc. This is where the role of the government and policy-makers becomes critical.
