Hydropower is the best
By:diego
WHAT IT IS
This is called hydroelectric power or hydropower. The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
Hydropower dams
Hydroelectric power is produced as water passes through a dam, and into a river below. The more water that passes through a dam, the more energy is produced. Once a dam is built, an artificial man-made lake is created behind the dam. Electricity is produced by a device called a turbine.
What's Good about Hydropower
- It is a renewable resource
- It is considered to be a green source of energy. It does not pollute itself.
About Hoover Dam
Hoover Dam, once known as Boulder Dam, is a concrete arch-gravity.Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power.
What they are doing to Stop floods
In addition to helping farmers, dams help prevent the loss of life and property caused by flooding. Floodcontrol dams impound floodwaters and then either release them under control to the river below the dam or store or divert the water for other uses.
