The researchers modelled how climate change would influence hydropower production for the tropical island of Sumatra and found a 40% increase in the ratio of hydropower production to demand at the 1.5˚C mark compared to 2.0˚C. The model used by the researchers included both climate, and economic factors which were used to explore how increased temperatures would influence hydropower potential. The study emphasized the importance of finding optimal locations for new hydropower plants considering the reality of a changing climate.
Hydropower is an essential resource for the world’s carbon free energy supply and is expected to be an important component for improving energy systems around the world. In Iowa, wind and solar energy make up a larger fraction of Iowa’s renewable energy than hydropower. In 2018, only 1.5% of Iowa’s electricity was generated from hydroelectric sources but it is thought that approximately 5% of the state’s electricity usage could come from hydropower if changes were made.
