When will hydroelectricity be accessible to the public?
Hydroelectricity has been available for public use for decades; hydroelectricity supplies around 20% of demand, and several countries have it as their main (in the case of Norway, almost only) source of power...
What are advantages and disadvantages of hydropower?
IT is renewable.
Aside from being renewable, the advantages of hydropower include:
- steadier, more consistent power.
- has 1,000 times more kinetic power than the wind.
- continuous production day and night regardless of the weather.
- smoother production of power than solar or wind power.
- higher power production than wind.
How is hydroelectric used in electricity?
when they build a dam they make it to where the water falls down and turns turbines. The turbines power generators that make electricity. it is actually pretty simple
How many people work at a hydroelectric powerplant?
the answer to your question is that OVER 9000! people work in a hydroelectric powerplant.
What programs of reduce reuse recycle support coal?
=what do you have to do to make me do my homework so that i could get question on recyclyed=
What are the hidden environmental and social costs of hydroelectricity?
Yes, because you have to make a river come to the area to make a dam work with make hydro power.
How many kilowatts a hour does a dam produce?
Most power plants produce several Megawatts of power. A Megawatt is one million watts.
Where did hydroelectricity come from?
Hydro electricity comes from two main power sources: the sun and gravity. The sun heats water and it becomes water vapor. The vapor rises and later precipiates at the source of a river or stream. Gravity pulls the water downwards along a riverbed. A hydroelectric power plant uses a wheel which turns as water travels past. The turning motion spins a turbine which powers a generator. Thus electricity is created
Is there an hydroelectric power plant in Ireland?
the following web site, www.hydroni.co.UK will give you information on hydro in NI and has a case study that may be of interest
also try Irish hydropower www.Irishhydro.com/ there is a list of all hydro electric stations and power generated
How much will hydroelectricity cost to use compared to the use of oil?
hydroelectriity costs 2 to 5 us cents and oil costs 100 dollars a barrel
Is hydroelectric energy sustainable?
Yes, in most cases. Wherever the natural water cycle continually replenishes the water source, power can be continually generated. There is no need ever to discover, mine, produce, or transport any additional water to the higher elevation from which it can generate energy as it moves under the effect of gravity through the generator turbines to a lower elevation.
How is hydroelectricity used to generate electricity?
Hydroelectricity works by harnessing the potential energy of flowing water. Gravity pulls water downstream, where it meets and turns the blades of a hydroelectric turbine. The turbine shaft turns the generator rotor, and that creates electricity in the same manner as with other electrical generators. While large hydroelectric plants that are part of a larger dam structure are common in the popular imagination, there are hydroelectric plants that use straight river flow and do not involve dams. Other models that are micro-generators and use ordinary streams to generate power.
Normally 5 to 10 years except for some really tiny ones 2 to 3 years.
When was hydroelectricity first used and where?
hydroelectricity was first used in 1878 in a goldfield. the inventors name is Lester Pelton.
