The document discusses sustainable development and financing renewable energy projects. It describes how many parts of the world have experienced economic growth but at the cost of environmental balance due to overusing fossil fuels. The COP21 objective is to limit global warming by switching energy sources from fossil fuels to renewables like solar power. As an example, the document summarizes the installation of Rwanda's first utility-scale solar field in 2015 that boosted grid capacity by 6% and will produce 8.5 MW of power. The $23.7 million project was completed in 12 months using a "blended finance" model with public and private funding.
