Frequently Asked Questions

What is the cost per kW of CWC’s turbines compared to conventional power technology?

The CWC 36kW cost is $2013 per kW of power production capacity. According to the AWEA, the average cost for electricity production capacity in the USA is $6096 per kW —- 303% higher.

Who is CWC’s competition?

We are aware of 334 companies in the small wind turbine space. Most of them only produce very small turbines (under 10kW).  None of them price their electricity production capacity anywhere as low as Change Wind’s price ($2013 per kW,  i.e. $72,440 per turbine).

Is the CWC 36kW competitive with 3-blade horizontal axis turbines? 

Yes, very much so.  On a cost per kW basis, the CWC 36kW sells for 72% below the competition in small and medium turbines.  It pruduces electricity using turbulent air only 10 meters over the surface, cutting in at just 6 mph, and reaching optimal efficiency at 12 mph.  Since it captures wind from any direction it does not have to be mechanically turned into the wind direction.

Are there any service issues I should be concerned about?

The CWC 36kW comes with a 10 year warranty which can be extended an additional 10 years as long as the annual maintenance has been carried out. The turbine needs an inspection, oil change, lubrication, electronics check, and power wash every 100,000 kWh, approximately once each year, costing roughly $500 in most areas.

How is Change Wind able to price its turbines so low?  

Change Wind passes along to customers the benefit of high efficiency and low cost manufacturing.   Production is performed at a re-purposed New England wire factory building obtained at below market cost, with on-site hydro-electric power at 66% below market cost.  The company uses state-of-the-art CNC and robotic machinery, extracting its craftsmanship from the sophisticated machinery and tools, not from expensive workmen.


Are there tax incentives for on-site wind systems?

On October 3, 2008, the Emergency Economic Stabilization Act of 2008, H.R. 1424, was enacted into law.  It includes a federal-level investment tax credit to help consumers purchase wind turbines for home, farm, or business use.  Owners of systems with 100 kW of capacity or less can receive a credit of 30% of the installed cost of the system.  It is available for equipment installed through December 31, 2016.  Source:
