What are three advantages of hydropower?

1. Renewable energy source: Hydropower is a clean and renewable source of energy that does not produce greenhouse gases or other pollutants. It relies on the natural flow of water, which is constantly replenished by the sun and rain.

2. Reliable and predictable: Hydropower is a reliable and predictable source of energy, as it is not affected by fluctuations in weather patterns like solar or wind power. This makes it a valuable resource for baseload power, which is the minimum amount of electricity needed to meet demand at all times.

3. Cost-effectiveness: Hydropower is a relatively cost-effective form of energy, with low operating and maintenance costs. Once a hydroelectric dam and power plant are constructed, they can generate electricity for decades with minimal input.
