Wind Power
Wind power is derived from the conversion of wind energy to become a useful form of energy to propel ships, make electricity or pump water. Wind is a renewable source of energy that is widely available and produces no harmful emission during operation.

What is the salary for wind energy jobs in the wind industry?
Wind energy jobs have a salary range averaging from $55,000 to $80,000 per year. Compensation depends on experience and position within a small, medium, or large company. Those classified as Wind Technicians are frequently compensated on a per diem pay schedule that contracts a daily payment for work in the field in addition to a base salary which is received regardless of field work. The Bureau of Labor Statistics indicates that the demand for new wind technicians and new support staff is projected to outpace supply over the next 10 years and average salaries are expected to climb each year from 2010 through 2020. Due to this increase in demand, wind tech training programs like California Wind Tech offer entry level training certifications for careers the wind industry. See www.californiawindtech.com
What was involved in GE's turbine recall?
In total, 22 GE turbines in the United States and overseas had to be shut down to be fixed; an additional 28 being shipped or installed required retrofitting with new components.
What energy change takes place in wind turbines?
They turn mechanical energy into electricity. The wind impacts the turbine blades causing them to rotate. The rotating blades turn a generator which produces electricity.
It is NOT tides. I did this on study island, and the CORRECT ANSWER: WAVES
How long has wind energy been used with wind turbines?
Vertical axis windmills were also used in China more then 2000 years ago The earliest documentation of a Chinese windmill was in 1219 A.D. by the Chinese statesman Yehlu Chhu-Tshai. Its main use was for grain grinding and the punping of water.
What is the name of the famous holland windmill?
If you mean the Kinderdijk, there are the most windmills in a row.
But we have more windmills, they're mostly located in the middle, top and west of the Netherlands, 'cause they were used to suck away the water, so that the land underneath it could be used.
The largest windmills (of the world) are located in Schiedam. They are called Schiedamse molens They are so large because they are made out of different layers.
If you are speaking of the windmill in Holland, Michigan: the 230 year old DeZwaan windmill is located on windmill island in the city of Holland Michigan.
What is used indirectly when winds and ocean currents are used to do work?
Thus, solar energy is used indirectly when the wind and some types of moving water are used to do work.
wind energy can be transformed into mechanical energy by wind mills .
How much power is used by a 35w bulb with 12v supply vs 110v supply?
it also depends on what meter you have, is it a KWH METER or a AH METER.
IF ITS A KWH METER(KILO WATT HOUR) IT COUNTS IN WATTS (35w PER HOUR.)
Does water turbines affect the environment?
Yes, water turbines effect the environment they turn kinetic energy (the waves energy) into mechanical energy, then to electrical energy so we can turn our lights on and off and use the computer you are using now. There are also wind turbines or windmills that do the same but instead of using waves they harness the energy of the wind. Environmental science will be very helpful in the future and everyone needs to do more to go green!
Where can you find wind turbines?
In Illinois, the north central part of the state, near Mendota. Usually you can find the mounted on tall, white, post-like towers. They're hard to miss, you can see them for miles.
When were the first wind turbines set up in the U.S.?
Small wind turbines were set up in rural areas of the Midwest during the early twentieth century, but power from utilities largely displaced them during the 1930s.
How long do wind turbines last for?
The turbine companies generally claim 20 to 25 years. Recent studies have shown that the life span is probably more likely to be around 10 to 12 years.
This is due to the electronics within the turbine itself.
Most electronics are build to last for 10 years as after this time it is thought they will be obsolete (which in most cases is probably true).
The wind turbines electronics are no different, while the blades and outside may well be build to last for a far longer time, the components are build to standard electronic component levels and are generally not build to last longer than the average 10 years (that's not to say that in some cases they wont though).
So there is a fair possibility that after 10 or so years the complete inside of a wind turbine will need replaced, effectively meaning the whole wind turbine will need replaced.
Should wind turbine blades be straight or on an angle?
If the wind turbine is generating, then the blade angle will be angled. The only time the blades will be feathered (turned so that they face straight into the wind allowing the wind pressure to be equal on both the front and back side of the blades) is when the generator is being serviced. In this position the blades will not try to turn.
This angulation of the blades is a variant of the wind speed, the stronger the wind the finer the pitch on the blade. The lighter the wind the more course the blade pitch will be. It is mandatory that the blades have to have variable pitch. When the generator is operational, the blades are in a constant state of pitch adjustment allowing the generator to remain at a constant rotation speed.
As more amperage load is required from the generator, the generator will slow down in rotation. This reduced generator speed is sensed by the generator's governor. The governor sends a signal to the variable pitch control circuitry that the generator is slowing down and to increase the pitch of the blades to bring the generator's speed back to its correct operational speed.
Why axial flow turbines blades are twisted?
The blades of an axial flow turbine have the aerofoil shape...
Also,for the axial flow turbines... Vf1=Vf2
The water strikes the blade surface at the same time from the root to its tip and a stream of water will leave the water at the correspondin trailing edge.
Therefore,for inlet to outlet,the radius and blade velocity will be the same,BUT the blade velocity will be different at different sections of the blade due to variation in the radial distance,which implies that the velocity triangles for each section of the blade will be different.In order to achieve shockless flow,the inlet and outlet triangles of a blade must vary from root to its tip,and therefore,axial flow turbine blades are twisted...
Wind is processed by farting cows attached to wind machiens! So never ever breath in wind, ITS TOXIC!
How much does a wind wurbine cost?
The cost of a wind turbine varies greatly depending on the size. A small turbine can be purchased for around 1200 dollars while large turbines can be several hundreds of thousands of dollars.
How do wind turbines affect people?
Wind turbines produce electricity for businesses that hire people.
Is wind power abundant or scarce?
Wind power is abundant.
There are 165,000 working wind turbines in the world in early 2012, and wind power world-wide is expected to have more generating capacity than nuclear in 2015 or 2016.
Wind is an abundant, free resource. Brazil alone has a projected wind potential generating capacity of 140 gigawatts.
Good onshore wind sites are fairly common across the world. Offshore wind farms, typically erected within a few kilometres of shore, add enormously to the potential sites for wind power generation.
Would a 600 watt wind generator be a good buy if you use 1200 kWh per month?
At 1200 kWh per month, you are using an average of 1600 watts. A 600 watt wind generator might seem to be a good buy, because it could supply one third of your energy.
You do have to consider total cost, including maintenance, and the storage and conversion system that would be needed to capture the wind energy when you are not actually using that amount of load.
You then estimate the potential savings. 1200 kWh, depending on your local electric rates, may be around $200US. Saving one third of that might take a long time to recoup the cost of the generator installation.
