Why hydropower does not cause global warming?

Hydropower does not cause global warming because it generates electricity by harnessing the energy of flowing water, which produces no direct greenhouse gas emissions during operation. Unlike fossil fuels, the process of generating hydropower does not release carbon dioxide or other pollutants into the atmosphere. Additionally, hydropower can help reduce reliance on fossil fuels, further mitigating climate change impacts. However, it is important to consider that the construction of dams and reservoirs can have ecological consequences, which need to be managed responsibly.
