The report, which is the product of qualitative research carried out in eight countries, assesses the extent of the finance gap for clean energy in developing countries and the barriers to scaling up private sector investment in low-carbon energy solutions. Overall, the report points to the need for an investment partnership between the public and private sectors with three equally important key elements: using developed country public funds strategically; ensuring stable long-term policy is in place in developing countries, and; addressing the incremental costs of clean energy technologies.
