How reliable is a hydroelectric dam?

Hydropower is Reliable. Because hydropower plants are the only major generators that can dispatch power to the grid immediately when all other energy sources are inaccessible, they provide essential back-up power during major electricity disruptions such as the 2003 blackout.

What are the pros of hydroelectricity?

Hydropower is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Hydroelectric power is a domestic source of energy, allowing each state to produce their own energy without being reliant on international fuel sources.

Why hydroelectric power is bad?

It does not pollute itself. Only the construction of power plants can be potential sources of pollution. It is a domestic source of energy. It is a renewable resource.
