Hydroelectric energy. -electricity produced by the force of moving water. -water is a source of renewable energy. -produces energy with no pollution. Harnessing moving water.
What is hydroelectric quizlet?
Hydroelectric Power. Also known as hydroelectricity; a form of energy generated by the conversion of free-falling water to electricity. Electricity is generated using the motive power of water. River Discharge. The volume of water flowing through a river channel.
What energy is hydroelectric?
Hydropower, or hydroenergy, is a form of renewable energy that uses the water stored in dams, as well as flowing in rivers to create electricity in hydropower plants.
What is hydroelectric power short answer?
Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity.
How does hydroelectric energy work quizlet?
Hydroelectric power converts energy (from flowing water) into energy (electricity). Potential energy in settled water turns into kinetic energy when it starts to flow down. Kinetic energy turns into mechanical energy when the flowing water has entered the turbines.
What is geothermal energy quizlet?
Geothermal energy is energy extracted from hot subsurface rocks, magma or heated water/steam. It is used to heat buildings, provide hot water and drive turbines to generate electricity. … This energy is known as gravitational binding energy, the energy generated when mass accretes.
What is an advantage of hydroelectric power quizlet?
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.
What is hydroelectricity for 4th class?
Hydroelectricity is the term referring to the production of electrical power through the use of the gravitational force of falling or flowing water.
What is meant by hydropower?
hydroelectric power, also called hydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy.
What are hydroelectric dams?
A hydroelectric dam is one of the major components of a hydroelectric facility. A dam is a large, man-made structure built to contain some body of water. In addition to construction for the purpose of producing hydroelectric power, dams are created to control river flow and regulate flooding.
What is hydroelectric energy Wikipedia?
Hydroelectricity, or hydroelectric power, is electricity produced from hydropower. … The cost of hydroelectricity is relatively low, making it a competitive source of renewable electricity. The hydro station consumes no water, unlike coal or gas plants.
What is hydroelectric energy and what type of energy does it produce?
“A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity.
How do hydroelectric plants generate electricity quizlet?
Terms in this set (10)
modern hydro plants produce electricity using turbines and generators, where mechanical energy is created when moving water spins rotors on a turbine. This turbine is connected to an electromagnetic generator, which produce electricity when the turbine spins.
How is electricity generated from hydroelectric dams quizlet?
Electricity is generated at a hydroelectric dam because water is directed toward a turbine which causes the turbine to spin which generates electricity.
How do we use a dams to generate electricity quizlet?
1. (a) Explain how hydroelectric dams are used to generate electricity: When water from the dam passes through, the turbines spin and creates mechanical energy, this is then turned into electrical energy through a generator. Hydroelectric power is produced as water passes through a dam, and into a river below.
