أستخدام طواحين الهواء او التوربينات الهوائية في العراق ملائم جدا للأستخدام في المنطقة الغربية من العراق بسبب أرتفاع معدلات سرعات الرياح في تلك المنطقة فمن خلال مراجعتي لمعدلات سرع الرياح المسجلة في العراق على مدى 30 سنة تبين ان المنطقة الغربية هي الأنسب لتركيب هذه المراوح الكبيرة والتي يمكن ان تنتج الواحدة منها 2ميكا واط وهي كافية لتغذية 400 الف منزل بكهرباء بمعدل 25 امبير لكل منزل وهي أرخص من الطاقة الشمسيةفلو فرضنا ان وزارة الكهرباء استخدمت الـ 15 مليار دولار التي هدرت من دون ان نلاحظ تحسن ملموس في الكهرباء الوطنية فسيكون مجموع المراوح الهوائية4285 مروحة وهي سوف تنتج 8.5 الف ميكا واط وهي أعلى من الأنتاج الحالي للكهرباء الوطنية والميزة الأخرى لهذه المنظومة انها سريعة التركيب جدا فخلال اقل من شهر يمكن تركيب الوحدة الواحدة بعدد فنيين لايتجاوز العشرة فأبمكان فريق مكون من 100 فني تركيب 120 وحدة في السنة.How much do wind turbines cost?Wind turbines come in many shapes and sizes, but here is a general guideline on how much they cost:Total costs for installing a commercial-scale wind turbine will vary significantly depending on the cost of financing, when the turbine purchase agreement was executed, construction contracts, the type of machine, the location of the project, and other factors. Cost components for wind projects include wind resource assessment and site analysis expenses; the price and freight of the turbine and tower; construction expenses; permitting and interconnection studies; utility system upgrades, transformers, protection, and metering equipment; insurance; operations, warranty, maintenance, and repair; legal and consultation fees. Others factors that will impact your project economics include your financing costs, the size of your project, and taxes.
The costs for a commercial scale wind turbine in 2007 ranged from $1.2 million to $2.6 million, per MW of nameplate capacity installed.
Most of the commercial-scale turbines installed today are 2 MW in size and cost roughly $3.5 Million installed. Wind turbines have significant economies of scale. Smaller farm or residential scale turbines cost less overall, but are more expensive per kilowatt of energy producing capacity. Wind turbines under 100 kilowatts cost roughly $3,000 to $5,000 per kilowatt of capacity. That means a 10 kilowatt machine (the size needed to power an average home) might cost $35,000-$50,000.
