Yes, wind turbines typically pay for themselves in the long run through energy savings and revenue generated from selling excess electricity back to the grid.

Are wind turbines nonrenewable?

The wind blows when it blows, but we assume it will continue from year to year. The turbines themselves are completely renewable, when they come to end of life. This would be when maintenance and repair is becoming uneconomic. ( that point is before installation) They never pay for themselves in their rated lifetime. They provide almost zero power when you add in the standby costs for fossil fuel backup. They kill birds and bast proving to be an environmental nightmare.


Is wind safe clean and will never run out?

Yes but it is not very competitive. People are not willing to pay the extra price in their bills required to have electricity from wind. Second disadvantage while wind generation is ecological the construction of the wind turbines isn't. You have to look at the whole life cycle of the turbines


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


Is there such thing as a air powered generator?

Yes, there are air-powered generators known as wind turbines that convert wind energy into electricity. Wind turbines have blades that rotate from the force of the wind, which powers a generator to produce electricity. These generators are commonly used in wind farms to generate renewable energy.


Are wind turbines feasible?

Yes, wind turbines are very feasible. There are approximately 165,000 wind turbines generating electricity world-wide. The wind industry world-wide is expected to have more generating capacity in 2015 or 2016 than the nuclear industry. Wind turbines last 20-25 years, and while they have high up-front costs they typically pay for themselves in 2-4 years, generating profits for the remainder of the time. As fuel costs are zero and maintenance requirements are lower than for fossil-fuel generating plants, they can be a very profitable investment. Wind energy in the best locations is currently coming in at 5-6 cents US per kilowatt hour. In a December 2011 energy auction in Brazil -- an auction where companies bid to build generating capacity -- wind farms won just under a gigawatt of the 1.2 gigawatts requested, with 39 out of the 42 winning bids. This is particularly relevant as the Brazilian auction was a completely level playing field; wind generation receives no subsidies of any kind in Brazil.


What is the difference between wind turbines and bigger wind turbines?

bigger wind turbines spread out larger and colect more energy A larger wind turbine is more efficient than a small one, and costs less to operate per KWH. For example, if you had two 750KW turbines, your total output of energy would be 1.5MW. You would have to have enough area to erect them and they can't be too close together. Then, you would have to pay for maintenance on two units as well as any repairs that may have to be made. Now, if you had just one 1.5MW turbine, you would require less space to erect it, and only have to maintenance and repair one unit. It would cost more to purchase initially, but would save expenses in the long run. And, you could get more energy from the same area as well.


Do the french have to pay for themselves?

As long as I understand the question, that's a yes.


Do wind turbines produce enough power to pay for their installation?

Over time, yes, the cost of the installation and ongoing maintenance of a Wind Power Turbine can be recovered from the sale of the electricity produced. However, the length of time required is dependent on the location (available wind) and the price you receive for the power generated.


How much approxaitely does it cost to set up a wind turbine?

Wind turbines are a form of renewable energy that are powered by the wind. The amount of time it takes for a turbine to start up depends on the wind speed on the day, on a very windy day they can be up to full speed within 2 minutes.


Is wind expensive or cheap?

Wins systems are extremely expensive and produce roughly 10% of the power they are rated at. A wind system I visited yesterday in Michigan will pay for itself in just under 200 years, unles it has a breakdown. Fossil fuel plants must also run to supply backup power to these wind systems. This fuel consumption is ignore to maintain a "green" status for the wind turbines. If we included this fuel into the overall power used to build, maintain and run wind turbines, the numbers would come out worse then a coal plant.


How many kilowatt's are in a wind turbine?

The Enercon E-126 has a rated capacity of 7.58 MW, has an overall height of 198 m (650 ft), a diameter of 126 m (413 ft), and is the world's largest-capacity wind turbine since its introduction in 2007. At least five companies are working on the development of a 10MW turbine.In the United States, residential wind turbines with outputs of 2-10 kW, typically cost between $12,000 and $55,000 installed ($6 per watt), although there are incentives and rebates available in 19 states that can reduce the purchase price for homeowners by up to 50 percent, to $3 per watt. The US manufacturer "Southwest Windpower," estimates a turbine to pay for itself in energy savings in 5 to 10 years.The American Wind Energy Association has released several studies on the small wind turbine market in the U.S. and abroad, showing that the U.S. continues to dominate the Small Wind industry. According to another organization, the World Wind Energy Association, it is difficult to assess the total number or capacity of small-scaled wind turbines, but in China alone, there are roughly 300,000 small-scale wind turbines generating electricity.The dominant models on the market, especially in the United States, are horizontal-axis wind turbines like those manufactured by UGEDo it yourself or DIY-wind turbine construction has been made popular by magazines such as OtherPower and Home Power, and websites such as Instructables, and by TV-series as Jericho and The Time Machine.DIY-made wind turbines are usually smaller (rooftop) turbines of ~ 1 kW or less. These small wind turbines are usually tilt-up or fixed/guyed towers. However, larger (freestanding) and more powerful windtubines are sometimes built as well. In addition, people are also showing interest in DIY-construction of wind turbines with special designs as the Savonius, Panemone, wind turbine to boost power generation. When compared to similar sized commercial wind turbines, these DIY turbines tend to be cheaper.Through the internet, the community is now able to obtain plans to construct DIY-wind turbines.and there is a growing trend toward building them for domestic requirements. The DIY-wind turbines are now being used both in developed countries and in developing countries, to help power homes, residences and small businesses. At present, organizations as Practical Action have designed DIY wind turbines that can be easily built by communities in developing nations and are supplying concrete documents on how to do so.Source : Wikipedia.
