Background information for facilitator

Background Information(for facilitator)

  • Hydropower is the force or energy or moving water. It has been transformed to mechanical energy for centuries. Water wheels have historically been used to power mills for processing grains, lumber, and mineral ore, among many other things. Now, moving water is used to power turbines, which spin generators to produce electricity. How much electricity is produced depends on the available hydropower. In most cases, hydropower comes from the potential energy of water collected behind dams. The greater the volume or water behind a dam, and the greater the height difference between the intake (above the dam) and outtake (below the dam) of water, the greater the hydropower available. Waterwheels at the bases of dams are spun by the force of the water falling over the dam, or through pipes.

  • Hydroelectricity is considered clean energy because it does not produce any harmful emissions such as greenhouse gases. Hydroelectricity is the most commonly used form of renewable energy in the world. However, hydroelectric power has its drawbacks as well. Dam failures have killed thousands of people in catastrophic floods. Dams also have a huge impact on the environment both upstream and downstream of the dam. Large reservoirs form upstream of the dam, and people and cities must be relocated out of the area of flooding. Upstream flooding also destroys and divides habitats. Dams create obstacles for fish such as salmon that must swim upstream to spawn. Dams also trap sediment, which piles up behind the dam and reduces the amount of water that can be stored. Water emerging from a hydroelectric dam may also be warmer than the normal temperature of the river. This can lead to changes for the plants and animals that live below the dam, as well as changing the ability of the river to freeze during winter.
