I have a project on wind energy... How much does it cost to set up and maintain windmills?
Extra (optional): what are the pros and cons of obtaining wind energy??

Pros/Cons- I would think that the windmills could always be made, yet natural resources will someday be depleted.
Try http://www.wikipedia.com
Roughly 1MW costs 1 million.
Cons: Expensive initial cost, environmental protection
Pros: Environmental protection, no pollution
prz Clinton shut down all the testing and development of this years ago..
but it is one of totally FREE sources we all need to make them get into.. because it is totally free ( well after they build them that is)
and solar to give even more electric..
good luck
great question
There’s also lots of info at http://www.windpower.org/composite-52.htm.
Quick estimate, they cost about $1000 per kW of peak power, and about 2-5% of that in annual maintainance.
Really depends on the size of wind capture device and power output you wish to achieve.
Now it has been 20 years but when I was 16 my mom and I both worked for a company that fabricated wind mills for power on Altamont Pass in California one of the first and largest wind farms for power Originally backed by the Best corporation in the 70’s The wind mills we made had blades 20 feet long and 3 feet wide attached to 1 kilo watt generators.
but they only ran at about 80% the Fayette corporation who sub contracted the work payed $21,000 per mast in 1986 and the last time I drove past they were still spinning that was Jan 2000.
Some where on those blades and masts My initials should still be there I welded them into the metal My mom made the generator housings and machined many of the parts.
I think with basic skills you could make a small one that could produce 60-80 amps 12 DC and with an interface inverter convert to 120-240 volts AC You can use old car generators pick them up cheap from a recking yard or even reconditioned or new from a parts store. Cheap enough.
They work great because they are already made to be exposed to the elements.
and are also made to last 8-10 years in a car.
use props from a ultra light aircraft carbon fibre just change the pitch so they will spin better with less wind.
Grease everything well to prevent drag and unwanted friction
Pros: in the US excess energy can be sold back to the local grid at market value, free power, help reduce the carbon footprint, save fossil fuels, reduce dependency on the grid.
Finally help start a trend that will reduce all our dependence on oil reserves.
Con: you will have to invest a bit of money, to be effective you will need to store energy for when the wind is not blowing or going too slow to provide adequate power, if it breaks you have to fix it, and you have wind mills around your house ( I think they are wonderful but some see them as an eye sore)
I am proud to have been a part of clean energy, I run my car on Bio diesel and am converting my van to run on alcohol, renewable energy source cleaner as well is the way of the future. also I live in the UK now and petrol and diesel are $8 per gallon
Wind turbines cost roughly $1 million per megawatt to build. They also need a support network and have to be maintained at a decent price.
Pros: Obviously it is a clean energy source, competative pricing.
Cons: Expensive to establish, can only be established where there are high winds (which isn’t where most of the population is), and there is a lot of concern as to what happens when you pull a lot of energy out of jet streams. No one is really sure what might happen. Bird strikes aren’t a real concern though as one might think.
