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.

∙ 6y agoWind Turbines are cheap to build from the low cost of materials it takes to build turbine.
ADDED: No, they are not very cheap to build, thanks to the relatively high total cost of materials, manufacturing, transport, labour and fuel involved; for a given electrical power rating of installation. They are relatively cheap to run because the "fuel" is free, but they still incur maintenance costs which can be high, especially for offshore installations. There is no such thing as a free lunch!

Why are wind turbines so high?
To get the maximum amount of wind. If they were low to the ground the wind levels would not be so high.
Why do wind turbines only have three arms and not many as in say a jet engine turbine Also why can't they be horizontal like the wind speed generators at airfields?
Yes, There are wind turbines with more than three blades... Basically that would only apply for the turbines which are not commercial like the turbines which are installed at home etc. and there are also wind turbines with horizontal axis, and again that would not apply to commercial wind farm. Usually Wind Turbines are BIG in size and mostly used to Generate Commercial Electricity so installing a Turbine with more than 3 turbines is not a viable thing.
Why are wind turbines built the way they are?
They are built so they have the maximum area possible to pick up wind, and the best quality so they last long, for the lowest price, so they are cheap to make. They have huge fan blades, that are tilted at the perfect angle.
Where to build wind turbines?
Well, its kind of obvisus to build one on a windy place for example: a hill, and some are built in the the sea. So mostly places where it is quite winddy, or where wind is likely to be.
What are the disadvantage of a wind turbine?
There Aren't many disadvantages only the cement used for the base and the cost for building and transporting it.AnswerThere are very few advantages. Wind turbines are one of the most expensive forms of energy generation, made affordable only because of enormous subsidies which are then passed on to consumers as elevated energy bills. They only produce a fraction of their rated capacity for most of the time. Their energy output is completely unpredictable. In the case of the UK, none is made in the UK, so taxpayers money is used to employ foreign workers to manufacture them and to increase the profits of foreign companies.On the other hand, if you are a landowner (paid to have them on their land), or a wind turbine manufacturer, or a wind turbine worker, then wind turbines are wonderful!
What are two negative things on wind energy?
1)Well sometimes there is no wind so the wind turbines that collect the energy are pretty useless (intermittent) 2) the turbines or wind collectors are pretty expensive. although the pay back is pretty quick 3) wind turbines to some are aesthetically unpleasing
What is downsides of wind energy?
Wind turbines are unsightly;Wind is not steady;Birds and bats are killed striking the blades of turbines;There is a large up-front investment;The return on investment is typically so long that subsidies are necessary to make instalation of turbines financially feasible;Wind turbines are prone to damage from storms.
Why are wind turbines so loud?
when wind gose threw the spikes on the the turbines it makes nosies , so faster louder it is.
How do wind turbines create energy if there is no wind?
They don't, there are brakes in the nacelle which is a part of the wind turbine. When there is no wind the brakes are on so that the rotors don't turn. In other words TURBINES DON'T MAKE ENERGY WHEN THERE IS NO WIND. They only produce power when the wind is between 14 and 28 mph.
Do wind turbines use radioactive substances?
So far there are no known reasons to use radioactive substances in wind turbines.
Would wind turbines be an option on north pole?
It depends if the people who make the wind turbines use batteries. Because without batteries, wind energy cannot be stored. They would also have to be very heavy duty batteries so that they don't freeze. Most likely wind turbines on the North Pole are not such a good idea
What does it cost to produce electricity using wind turbnes?
Wind turbines are enormously expensive to build and tricky to maintain. So far, they haven't really been a practical source of energy. New designs and more efficient turbines have been improving the prospects for wind power, but older turbines are prone to occasionally catastrophic and spectacular failures. The impact of wind turbines on bird populations has also been pretty bad; at least one pundit has described them as "eagle shredders".
Why are wind turbines not placed next to one another?
The wind farmers usually want to spread them out so the propellers do not collide. They also want to spread the turbines out so that they can catch the wind wherever it is.
How is water or wind energy renewed?
wind is renewed by its self but water energy can be renewed in many ways there is water turbines and wind turbines for wind so tecnicly yes it is renewed i guess
Why are wind turbines so high?
To get the maximum amount of wind. If they were low to the ground the wind levels would not be so high.
What are the bad things about wind turbines?
Unsightly. Dependent on the wind blowing. So electrical output is irregular and intermittant.
Why do you need wind turbines?
we need wind turbines because they give us energy i dont know really i am just so bored :P
