  • Dams: Falling water spins turbines to generate electricity.
  • Wave power: Ocean waves transfer their energy to moving machinery which generates electricity.
  • Tidal power: Tidal water rushes through narrow channels turning electricity generators.

gravitational energy


What term describes hydropower as an energy source?

renewable


Where does hydropower come from and how is it collected?

Hydropower comes from the energy of flowing or falling water, primarily harnessed from rivers, dams, and waterfalls. It is collected by diverting water through turbines in a hydropower plant; as the water flows or falls, it spins the turbines, converting kinetic energy into mechanical energy. This mechanical energy is then transformed into electrical energy through generators, providing a renewable source of electricity.


What is the process of operation of a hydroelectric power plant?

Worldwide, hydropower plants produce about 24 percent of the world's electricity and supply more than 1 billion people with power. The world's hydropower plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil, according to the National Renewable Energy Laboratory. There are more than 2,000 hydropower plants operating in the United States, making hydropower the country's largest renewable energy source.In this article, we'll take a look at how falling water creates energy and learn about the hydrologic cycle that creates the water flow essential for hydropower. You will also get a glimpse at one unique application of hydropower that may affect your daily life.


What is the correct energy transformation in a hydropower dam?

In a hydropower dam, the primary energy transformation occurs when the potential energy of stored water in a reservoir is converted into kinetic energy as the water flows down through turbines. This kinetic energy is then transformed into mechanical energy as the turbines spin. Finally, the mechanical energy is converted into electrical energy through generators, producing electricity for use.
