The benefit of hydroelectric power is **it has low operating costs once built**. Once the dam and infrastructure are established, the ongoing costs for maintenance and operation are relatively low compared to fossil fuel energy sources. Additionally, hydroelectric power is a renewable energy source that does not pollute the air in the same manner as fossil fuels.
