Declining cost of renewables and climate change curb the need for African hydropower expansion.

We built an integrated modeling framework that captures individual power project characteristics within an energy system model that simulates three socioeconomic scenarios that harmonize land-use change, climate impacts on water availability, final energy demands, and climate policy options. Yet, in the short term, especially in the transition to a net-zero emissions energy system, hydropower represents a cheap alternative to displace fossil fuels, especially coal. Cost-optimal hydropower expansion. [Extracted from the article]
