Is hydroelectricity carbon neutral

Answer 1

Hydroelectricity is often considered a renewable energy source and is generally viewed as carbon neutral during its operation because it does not emit greenhouse gases while generating electricity. However, the construction of dams and reservoirs can lead to significant carbon emissions due to land clearing and the decomposition of submerged organic matter. Additionally, the impact on local ecosystems and communities can raise environmental and social concerns. Overall, while hydroelectricity has a lower carbon footprint compared to fossil fuels, it is not entirely without environmental consequences.
