Hydroelectric power is generally considered to be a cost-effective energy source in the long term due to low operational and maintenance costs once the infrastructure is established. However, the initial capital investment for building dams and plants can be high. Additionally, economic viability can be influenced by factors such as location, environmental impacts, and regulatory challenges. Overall, while upfront costs may be significant, hydroelectric power often results in cheaper electricity over time.
