How much Wind Turbine’s Costs?
Wind turbine cost will be a major factor when investigating if it is economical to install and use wind power. There are several different parts to a turbine and you will need everything installed in order to harness the power of wind. The cost is generally determined by the tower height, generator size and rotor diameters. Basically you are collecting the energy needed for the wind to turn the rotor blades.
There are several wind farms around the world that use wind turbines to create electricity. Over 3, 000 MW of wind power is produced in Denmark by several wind farms that they have in the country and offshore. This takes over 5, 500 wind turbines to collect this amount of energy. If you drive over the mounts in to San Francisco you will see them on the mountains. There are also some wind farms around Palm Springs that collects wind power. The more kW you are interested in collecting then in general the more expensive the wind turbine costs associated with it. A single wind turbine that produces 700 kW can cost around half a million dollars. Smaller wind turbines can cost between $150, 000 to $200, 000 dollars though many companies are looking to design smaller more economical wind turbines that can be used for residential homes. A smaller wind turbine can produce 100 to 200 kW of energy.
With the expense involved with purchasing a wind turbine it is more cost efficient to install a larger one as the cost needed to produce a larger turbine is not much more expensive then a smaller one. If you are interested in produce 600 kW of energy rather than 150 kW, so quadrupling the power, the cost only triples, it does not quadruple.
A slight guide for the cost of a wind turbine is that it will cost you $1, 000 per kW power. Collected wind power is measured by kW per hour and your cost will be based upon kW per hour. The most wind turbine competition is found at the 1, 000 kW per hour range as this size is built by many different companies.
Besides purchasing the wind turbine there are other costs that are involved with the wind turbine installation. All of these additional costs need to be take account of as they can dramatically increase the cost of your wind turbine. Some additional costs include cabling, connection to the electrical grid, transformer, road construction, and turbine foundations.
The soil where you want to install the turbine will dictate the type of foundation you will need to keep it upright and steady. If you are installing your turbine in a remote area then you may have to build roads in order to get all of the equipment and the wind turbine to the site. Actually getting your turbine to the site will accrue some steep transportation costs, particularly if you are installing many turbines or very large wind turbines.
With all of these costs it actually makes more sense to install several rather than one wind turbine. Ultimately this means you are doing everything in bulk. It is less expensive to install 12 in one area rather than building multiple roads to several different locations and then connecting each of those wind turbines to an electrical grid form several different areas.
Man wind turbines are being installed off shore as individuals in urban areas can also take advantage of the power created form wind turbines. Offshore wind turbines are perfect for those communities that do not have any land that can be used for wind farms. One of the largest wind farms is located of the shore of Denmark at Horns Rev.
Wind power has been used for years. The very first types of wind turbines were in the form of wind mills. Wind mills were used to grind grain into flour and much more. Wind power is the cleanest and most efficient form of energy as it does not produce pollution and wind will always be available.
