How high are wind turbine blades above the ground?
Wind turbines are usually 100-120 m high above the ground.The height is usually fixed based on the diameter of the blades.But if the height increses the available wind power increases yielding more power.But the cost also increases.So based on the diameter of blades height is decided.usually for a 80m dia blades the height ranges between 100-120m
What are the bad reason for wind turbines?
Wind farms are bad because it can bring down value of peoples house when tryin to sell them. Wind farms also require a huge amount of space,make a tremendous amount of noise and can kill wildlife. Such as birds of flight, they can come tumbling down with one strike of lightning hitting those blades and that would mean a lot of work. Bird in flight can also damage the turbine and thy would mean passing over lots of money.
The average 2 mw wind turbine produces a sound eqaul to 45 decibels
How much approxaitely does it cost to set up a wind turbine?
Wind turbines are a form of renewable energy that are powered by the wind. The amount of time it takes for a turbine to start up depends on the wind speed on the day, on a very windy day they can be up to full speed within 2 minutes.
The short answer is yes. BUT, if you do not turn off the breaker on the circuit you plug into, it will back feed the breaker box and the line going into the house. This can be very dangerous to the utility workers trying to repair the lines outside the home. At the very least turn off the main breaker until the electric has been restored. Also make sure you do not over load that circuit with too many appliances. If it is a 15amp circuit, look at the devices you will have connected and running and make sure the total amps used does not exceed that capacity. That would be a possible fire hazzard. I did this today, but I used and outside outlet and was able to run our furnace blower and a few lights without any problems.
How does a turbine and generator work?
The turbine converts pressure & heat energy (in steam turbine & gas turbine), velocity energy (in hydro turbine) into mechanical energy which produces rotation of the turbine. This mechanical force is used to rotate the rotor(which is coupled with the same shaft as that of turbine) of the generator which converts this mechanical energy into electrical energy.
Why are wind turbines so expensive to make?
because the government cant fund for the research and the utilities needed to make wind turbines and because even though they help the environment it still cost workers to make and place and move them to where they needed to be.
The Francis turbine is an inward flow turbine that is the most efficient and widely used water turbine in the world today. It works best in higher head (pressure) applications, and hydroelectric power plants at big dams use these guys to make lots of watt-hours. The term "inward flow" means that the turbine itself (the thing with the blades that the water "presses on" to make the thing turn) has the water directed from the outside of the turbine wheel in onto the blades, and through them to a "center area" for the water to exit. The unit is darn efficient. Pictures are a mouse click away. Use the link to surf on over to our friends at Wikipedia (from which some of the data here was gathered) for more information and the cool pics that really show a viewer how the unit works.
How big is the biggest wind turbine in the world?
I think they go up to 2 Megawatts
Wrong, GE recently purchase a company called ScanWind who manufactures a 4.5MW off-shore wind turbine. Look for larger units to come soon some up to 6MW!
How is wind energy used to produce electricity?
According to the American Wind Energy Association, the forces of wind are converted to electricity through the use of a wind turbine. In a standard modern wind turbine kinetic energy from the win's moving air molecules is turned into rotational motion by the rotor. A rotor is a three-bladed device (looking like the rotor on a household fan except much larger) that sits at the front of the wind turbine. Wind causes the rotor to turn a shaft that transfers the motion to a nacelle, the large housing at the top of a wind turbine tower. Inside the nacelle, the rotating shaft enters a gearbox that increases the shaft's speed of rotation. The fast rotating shaft is connected to a generator that converts the movement into electricity and medium voltage.
Once the wind has been converted into medium voltage electricity, equivalent to a few hundred volts, that electricity goes down through heavy electric cables in the tower to a transformer which is able to increase the voltage up to a few thousand volts - the distribution voltage. This voltage power, which flows more easily through electric lines, travels through underground lines to a collection area where the power can be combined with other wind turbines.
This electricity from wind power is usually sent to nearby farms, homes and towns for usages. If it is not sent to towns and homes is it sent to a substation where the voltage is increased greatly to a few hundred thousand volts (called transmission-voltage power) to be sent through very tall transmission lines to distant cities and factories.
Where are wind turbines most found?
That would be China.
Here is the list of top 10 countries by wind power production:
What does it cost for large installation of wind turbine?
THE ANSWER IS GOING TO BE EVASIVE. there are blades 50' long and there is blades 10' long. Unless you are specific nobody knows. And the actual cost is hidden usually from state to state because of taxes breaks.
What are some of the different designs of wind turbines?
country side wind turbines and modern turbines
How many people use wind turbines?
people are starting to turn to Wind Turbines because they are finding that they are economically safer and there cattel are not interested in the wind powered stations. i hope that answers your Question ifnot contact me on 0405072422
Winds are the result of air moving from areas of high pressure to areas of low pressure. They play a crucial role in redistributing heat and moisture around the Earth, affecting weather patterns and influencing climate. Winds can range from gentle breezes to powerful storms, such as hurricanes and typhoons.
One way is to cut a piece of construction paper, staple equal-sized streamers on one side in a row ( ten is a good amount), then form a circle with the paper and staple it. Make at least 3 (6 would be better), equally spaced holes, with a hole-punch. Attach a string to each hole, tie a knot in all the strings at once, so that all the strings are equal in length and attach it to a pole (the taller, the better).
What is inside a wind turbine?
A wind turbine generates electricity by converting its kinetic energy into electric energy. The kinetic energy of the wind transfers to the turbine, and the kinetic energy of the turbine converts to electric energy as it spins within an electromagnetic field.
Usage and advantage of tertiary winding?
A teriary winding is useful for many things. A delta tertiary will help balance voltage/currents to some degree. It also traps third harmonics. In substations, the substation power is often taken from the tertiary. It can also be used as a lower voltage connection for inductors (much cheaper, due to the lower voltage vs. primary connected inductors).
What is a wind turbine used for?
Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun. The wind turbines spin round and produce electricity. This is a good way of producing electricity as the wind will never go.
How can a 5mph wind turn a wind turbine?
With a new kind of wind turbine called a vertical axis wind turbine (VAWT) that can produce electricity in winds as low as 5 mph.
Wind energy is made by spinning turbines. The wind spins the wind turbines and they generate energy.
How are wind turbines transported?
Energy can not be created or destroyed but only changed from one form to another. Wind energy is changed to mechanical energy of the turbines. The turbines can then generate electricity.
How does a wind up torch work?
all windup watches work by a mainspring that is wound up really tight, the spring wants to let go as soon as it is wound up tight. as you wind up the mainspring that parts in the watch start to move and the watch starts to keeps time. this is called a balance action. the balance wheel has a hairspring under it that returns the balance wheel to its main position as you wind the mainspring the force of it puts tension on the parts and that is how the windup watch works.
Wind turbines have been around for 124 years.
It has been around from 1888 - 2012.
Texas and California are the leaders in wind generation in the United States.
