Wind power is frequently marketed as a “green” energy source, and it is true that the energy is derived from a renewable source, namely the wind. However, what about the turbines themselves? What color are they?

The answer is usually the same, whether it’s a large wind farm turbine or a little residential wind turbine: most wind turbines aren’t built sustainably. Because most commercially available wind turbines are now manufactured with a lot of plastic and fiberglass and coated with a variety of chemical protectants, none of my suggested models receive more than three leaves.

They’re also tough to recycle, if not impossible. However, certain models are superior to others, which is why they are listed here! Fortunately, several clever designers are working on ways to construct entirely recycled and recyclable wind turbines with a far smaller environmental impact during their lifetime.

What is the total number of wind turbines in the area?

The US Wind Turbine Database (USWTDB) has more than 70,800 turbines as of January 2022. Since 1980, more than 1,500 wind generating projects in at least 44 states have been built with these turbines (plus Puerto Rico and Guam).

What is the difference between a Type 1 and a Type 2 wind turbine?

A Squirrel-cage Induction Generator (SCIG) attached directly to the step up transformer distinguishes a Type 1 wind turbine.

The turbine rotates at a rate that roughly matches the frequency of the electrical grid.

When the turbine shaft rotates faster than the electrical grid frequency, a negative slip occurs; when the positive slip and power motoring conventions are applied, real power is generated.

A given wind speed will result in a near linear turbine speed, torque profile under steady conditions.

Sudden fluctuations in wind speed result in a limited rate of change in electrical output due to the system’s mechanical inertia.

What are the various wind turbine sizes?

The size of the wind turbine you’ll require is determined by your needs. Small turbines are available in sizes ranging from 20 to 100 kilowatts (kW). Smaller turbines, known as “micro” turbines, range in size from 20 to 500 watts and are used to charge batteries in recreational vehicles and sailboats.

Turbines ranging from one to ten kW can be utilized in a variety of purposes, including water pumping. Wind energy has been utilized to pump water and grind grain for ages. Although mechanical windmills are still a viable and cost-effective alternative for pumping water in low-wind locations, farmers and ranchers are discovering that wind-electric pumping is more versatile and allows them to pump twice as much for the same initial expenditure. Furthermore, mechanical windmills must be installed directly above the well, potentially limiting the use of available wind resources. Wind-electric pumping systems can be installed wherever there is the best wind resource and connected to the pump motor through an electric connection. Mechanical windmills, on the other hand, can provide more effective water pumping in locations with little wind.

Depending on the quantity of electricity you wish to generate, turbines used in residential applications can range in size from 400 Watts to 100 kW (100 kW for very heavy loads). Establish an energy budget for home applications and investigate if financial incentives are available. This information will assist you in determining the size of turbine you will require. Because energy efficiency is typically less expensive than energy production, making your home more energy efficient will likely save you money and allow you to minimize the size of the wind turbine you’ll need (see How Can I Make My Home More Energy Efficient?). Manufacturers, dealers, and installers of wind turbines can assist you in sizing your system depending on your energy needs as well as the characteristics of your local wind resource and micro-siting.

A typical home uses about 10,649 kilowatt-hours (kWh), or about 877 kWh each month on average. A wind turbine rated in the range of 5 to 15 kW would be necessary to provide a meaningful contribution to this demand, depending on the typical wind speed in the area. In a location with a yearly average wind speed of 14 MPH (6.26 meters per second), a 1.5-kW wind turbine will cover the needs of a home consuming 300 kWh per month. The projected yearly energy output of the turbine as a function of annual average wind speed can be obtained from the manufacturer, dealer, or installer. The manufacturer will also disclose any maximum wind speeds at which the turbine is designed to safely operate. To keep the rotor from spinning out of control in exceptionally high gusts, most turbines feature automatic overspeed-governing mechanisms.

This information, combined with information about your local wind resource (wind speed and direction) and your energy budget, will aid you in determining which size turbine will best fulfill your electricity needs.

What factors should I consider before purchasing a wind turbine?

Size, wind resource, availability, dependability, warranty, spare parts availability, and proximity of operation and maintenance teams are all factors to consider while choosing a turbine.


Wind projects, in general, are modular energy facilities with one to one hundred turbines or more. The amount of land available, the number of investors and the size of each investor’s contribution, the financing available for the project, the ability of the transmission or distribution grid to handle the additional energy from the project without significant system upgrades, and the number of turbines available are all factors that influence the overall size of a wind project. The scale of the project is often determined by a combination of one or more of these criteria.

For example, a project might start with a capacity of 10 MW. You may discover after going through part of the interconnection process that a project larger than 8 MW may incur considerable connectivity expenses. It could be prudent to create only an 8 MW project in this instance. In other cases, regardless of the project’s size, significant interconnection fees may be incurred. In these situations, it may be more cost-effective to build a much larger project to spread the interconnection and other associated expenditures among as many turbines as possible. The most important aspect here is economics. The size and number of turbines should be determined by maximizing the return while taking into consideration constraints.

The size of the turbine model that will be utilized at a project will be determined by the models that are available, the wind resource at the site, and the ability to undertake maintenance. Because there are few cranes capable of lifting huge cargoes to the top of tall towers, larger machineries on taller structures can result in more costs and delays when changing important components. Smaller turbine models may be easier to maintain, but they may produce less money due to a shorter tower or a less efficient machine.

Keep in mind that project and turbine size should be determined based on the possibilities that will deliver the best economic return for investors as well as the ease of obtaining and maintaining equipment.

Wind Resource and Climate

Wind turbines are classified by the International Electrotechnical Commission (IEC) into four classes based on wind resource and environmental criteria (I-IV). The highest wind and turbulence criteria are described by IEC class I, while the lowest wind and turbulence criteria are described by IEC class IV. Turbines with larger rotors are designed for high energy capture in low wind regimes. Turbines intended for high wind locations, on the other hand, tend to have bigger nameplate generator ratings and smaller rotors. In order to identify which turbine is best for your location, you may need to acquire gust data. Consider a wind turbine model that has a proven track record in locations with similar wind resources and climates to your location.

Availability for Purchase

The turbine you select must not only fit your project and site requirements, it also must be available for purchase within your time frame. Because many of the world’s largest wind turbine manufacturers are based in Europe, transportation and timing are crucial considerations. Furthermore, it is more cost effective for manufacturers to supply customers requesting large numbers of turbines, which can make finding a single turbine or a small number of turbines difficult.

Used Wind Turbines

On the market, used wind turbines are becoming more common. It’s best to proceed with caution when purchasing old wind turbines. They may be less expensive up front, but they are more likely to have operational issues. Because of the additional risk, lenders may be hesitant to finance older equipment. In general, if you’re thinking about buying used, you should make sure you know:

  • The machine’s operational history;
  • Why was it taken out of service?
  • What steps have been taken to restore the machine’s functionality?
  • If the machine is covered by a manufacturer’s warranty;
  • What kind of spare components are available; and
  • What kind of competent labor is available to repair the machine?

If you go down this road, you must consider these difficulties as well as all of the other turbine issues. A firm understanding of the risks connected with old equipment should be at the forefront of your project’s thinking.


Turbines that aren’t producing energy are a waste of money, and a machine that breaks down frequently will cut into your profits quickly. Take into account that the majority of projects are designed to be operational 98% of the time (“98 percent availability). This means that each turbine can only be shut down for about 7 days per year for scheduled and unscheduled maintenance.

Choosing a machine with a proven track record in the field, as well as a manufacturer with a reputation for high-quality equipment and prompt reaction when issues emerge, will help keep your project on schedule. To find out who is selling the best machines and which models to avoid, talk to as many different developers, maintenance business representatives, project investors, consultants, and others in the sector as possible. It may be worth considering if you have to wait a bit longer for a good equipment and can fit it into your project schedule.


Most wind turbine manufacturers provide a two-year parts and labor warranty, which may also include a power curve and availability guarantee. Manufacturers of turbines frequently offer to extend the warranty to five years for an additional fee. These warranties will cover design and manufacturing faults, as well as parts and labor replacement. For smaller projects, extending the warranty on the machines is usually a good idea, and financing institutions may require it before granting money to the project. While the project accumulates a contingency reserve for any major equipment failures after the warranty period expires, an extended warranty will give protection against major failure.

A contingency fund is money set aside in a separate reserve account for the project to access after the warranty has ended to pay for costly repairs or component replacements that are not covered by scheduled maintenance, and it is an important item to include in your project’s business plan.

The turbine sales agreement will include the machine’s delivery timetable (which is critical due to the tight building and connecting timeframes), components, and labor. It may also cover the power curve, guaranteeing that the machine produces as much electricity (and money) as you anticipated in your business plan, though the technological requirements for monitoring the power curve can be prohibitively expensive for smaller enterprises.

Proximity of Operation and Maintenance Teams

If your turbine supplier or another qualified vendor has active operations and maintenance teams in your area, your operations and maintenance costs will be greatly reduced. As a result, the cost of travel is decreased, as is the availability of the vehicle due to unscheduled repair.

Service Contracts

The major turbine manufacturers and a variety of approved third-party vendors offer service contracts. The size and proximity of your project to other projects employing the same manufacturers will affect the terms and costs of these contracts. If your project is tiny and/or far distant from other projects, certain turbine manufacturers may refuse to give service contracts or may offer inflated pricing to entice you to sign one. Third-party O&M companies may be used to service machines, but if they are not approved by the manufacturer, the warranty may be voided.
