Social benefits are primarily economic growth and improved flood control while negative social impacts are displacement adverse effects to human health and livelihood changes.

How is hydroelectric energy harnessed?

In an impoundment facility a dam is used to control the flow of water stored in a pool or reservoir. When more energy is needed water is released from the dam. Once water is released gravity takes over and the water flows downward through a turbine. As the blades of the turbine spin they power a generator.

How is the electricity produced by hydroelectric dams transferred to customers?

There it hits the blades of turbines with such force that they spin like a propeller. As they spin they create electricity which goes through cables up to towers on top of the dam. From there it is sent out on power lines for use.

How are hydroelectric power plants used for flood control?

Flood control dams capture floodwaters and can then release them under controlled circumstances to the river below or the water can be stored and utilized to meet other needs not only avoiding potential disaster but turning the event into a future benefit.

How does a run of the river hydroelectric dam work?

In general projects divert some or most of a river’s flow (up to 95% of mean annual discharge) through a pipe and/or tunnel leading to electricity-generating turbines then return the water back to the river downstream.
