Even a few years ago, renewable energy played only a small role in most countries’ energy planning. While governments and publics were eager to increase the share of renewables in their energy systems, the economics of doing so were challenging. There were also serious concerns about the impact on the electricity grid of adding too much capacity from variable renewable energy sources, such as solar and wind.

"Renewables are no longer a marginal business. We are talking about levels of energy that can bring light to thousands of households, grow businesses, meet the needs of cities, and drive entire economies." — Anita Marangoly George, Senior Director, Energy and Extractives Global Practice, World Bank Group
