What is the meaning of Gross head in hydro power projects?
it is the difference in elevation between head and tail water
Why is hydroelectricity reusable?
Because water is always flowing, therefore making hydroelctricity (with the help of humans)
What is a sustainable energy source?
sustainable energy is the kind of energy that will never run out. example: solar energy, wind energy,etc.
Is Hydro electricity non renewable?
as long as the flow is not interupted, it is long-living and not directly polluting- one can imagine ( in the wake of Deep Horizon horrors) accidents like drums of paint used to coat the generators falling into the water, leaking, etc- but in normal operation Hydro power is in a sense ( once built) cost free and does not pollute. it has the drawback of being stationary, true of all powerhouse applications. Does that answer your question?
When was hydroelectricity first used?
- The first hydroelectric power station was built in 1878 in Northumberland, England. It could power one single arc lamp.
- Niagara Falls began producing electricity in 1881.
- Edison opened the next plant in Wisconsin, USA, in 1882. It produced 12.5 kW.
Well...first you need to get a motor(brushless, about £15 pounds on eBay), li-po batterys (2-3 cell) (£10 on eBay) and a receiver with crystal. you will also need a servo(s). the design is up to you! the shassy could be made out of plexiglass to PVC to baulsa wood. anything really.
How does the technology of hydroelectricity work?
Believe it or not, nuclear fission reactors function in much the same way - the nuclear fuel is used to produce a huge quantity of heat that boils a huge quantity of water, and the resulting steam pressure is used to drive steam turbines.
How does hydroelectricity harm us?
by the rain and by not going green even by littering on ground and the most is by gases in the air
What uses Hydroelectric power?
Hydroelectric power plants. They have dams and generators. Water flows through a dam, which spins generators that produce hydroelectric electricity. (Fun Fact: The Hoover Dam is the biggest hydroelectric power plant.)
Is money a nonrenewable resource?
the presses are there to print money when they are supposed to so I think it is clear that is a renewable resource.
What is the history of hydro-electric power?
1881- Niagra AFalls City street lamps powered by hydropower 1882-First hydroelectic power plant was built in Appleton, Wisconsin, on the Fox River. 1886-About 45 water-powered electic plants in the US and Canada 1887-San Bernardino, California, opens first hydroelectic plain in the west 1889-Two hundred electic plants in the US use waterpower for some or all generation 1901-First Federal Water Power Act 1907-Hydropower provides 15% of the US electrical generation 1920-Hydropower provides 25% of the US electrical generation. Federal Power Act establishes Federal Power Commision authority to issue licenses for hydro developement on public lands 1937-Bonnevill Dam, first Federal Dam, befins operation on the Columbia River. 2003-About 10% of the US electricity comes from Hydropower
What are the bad uses about hydroelectric power?
there are no bad uses of hydro electricity and cant be
What are the uses of hydroelectric energy today?
Hydroelectric energy is electricity and is put on the national grid for use by the public. It is used for pretty much every modern process of anything, in some way or another.
How is most of the electricity in the US produce?
Most of the electricity in the US is produced by burning fossil fuels such as coal, natural gas, and oil in power plants. Nuclear power and renewable energy sources like wind, solar, and hydroelectric power also contribute to the electricity generation mix.
What energy is produced when water is released through dam turbines?
Electrical energy - the turbines drive generators
Which country first used hydro-electric power?
How does hydro energy generate electricity?
Hydro energy generates electricity by using the kinetic energy of flowing water to turn turbines connected to a generator. As the water flows over the turbine blades, it causes them to spin, which then activates the generator to produce electricity. This process is clean and renewable, with minimal impact on the environment.
How does hydroelectric energy produce electricity?
The water from a river/dam is allowed to plunge into a depth below to create potential energy, this potential energy is harnassed and converted into kinetic energy when the at the bottom of the drop the water fell into there are turbines (propeller shapes) which the water will crash onto and drive the turbines into motion, and in the process converts the potential energy into kinetic energy. This energy from the turbines can then be saved and stored for use on the national electricity grid for later use.
A:IN A HYDROELECTRIC GENERATOR THE POWER PRODUCED IN THIS MACHINE IS DIRECTLY PROPORTIONAL TO THE TORQUE PRODUCED BY THE WATER TURBINE.i.e.,BY VARYING THE WATER FLOW THROUGH THE TURBINE WE CAN INCREASE OR DECREASE THE POWER OUTPUT AFTER THE SYNCHRONISATION OF GENERATOR TO THE GRID. BEFORE SYNCHRONISATION THE TORQUE WILL CHANGE THE SPEED OF GENERATOR.THE POWER PRODUCED WILL VARY ACCORDING TO WATER FLOW UPTO THE MAXIMUM CAPACITY OF GENERATOR.Is hydrothermal energy the same as hydroelectric energy?
No. Hydroelectric power is any power coming from water, usually from its movement, but also from its heat (thermal).
Hydrothermal power is power generated only from the temperature of the water (hot springs, ocean thermal, geothermal).
Why is hydro power good for the environment?
Because hydro means water
So it is power made from water
Water is and infant resource so there won't run out
