<br>A growing population and increasing energy demand have spurred investments in hydropower generation in Africa. At the same time, the cost of power from other types of renewable sources has continued to drop. Carlino et al. explored the ramifications of this trend on the economics of hydropower. They analyzed the African energy landscape from 2020 to 2050, and predicted that the declining cost of wind and solar power will make a large fraction of the current hydropower candidate installations economically uncompetitive over that period. Cooperation between countries could help to overcome the regionally unequal distribution of investment costs and potential energy deficits. (editor's summary)<br></p>
