The Best Residential Wind Turbine in 2024

You can’t see the wind, but you can feel it. You may even marvel at its power when it’s blowing particularly hard. One great thing about the wind is that it can provide electricity for your home if you harness its power using a wind turbine.

Home wind turbines are great ways to generate green energy because they produce electricity from a renewable source, the wind. Also, they don’t emit earth-damaging greenhouse gasses in the process. Thus, installing a small wind turbine provides you with an eco-friendly alternative for a backup or primary energy source.  

As power consumers strive to move away from fossil-fuel-sourced electricity towards more sustainable energy sources, they actively explore other power suppliers that don’t harm the planet. Wind turbines are just some of the alternatives some homeowners have adopted to push their goal forward since wind power is considered one of the most cost-effective renewable energy suppliers. 

Let’s determine whether home wind turbines can meet your home’s energy requirements and save you money on your electricity costs. 

What is a Residential Wind Turbine?

Residential wind turbines are smaller versions of the gigantic turbines you see dotting the sides of highways in the countryside. While those large turbines have blades of over 170 feet (52 meters, on average), a home wind turbine is more compact. It typically measures 1.5 to 3.5 meters (4 ft 11 in – 11 ft 6 in) in diameter. 

However, the two versions work the same way. They harness wind energy and transform it into usable electricity. The wind spins the turbine to power a rotor, which then turns a small generator into the wind turbine. This generator produces energy as it runs.  

A home wind turbine connects to the electrical system through an inverter, which converts the DC power from the turbine into AC electricity most homes use. Although small wind turbines are tinier than commercial wind turbines, they can produce enough energy to power your lights and electrical appliances. Depending on the wind speed in your area, they can help lower electricity bills by around 50 to 90 percent.  

Components 

An electrical system driven by wind power is made up of several components that work together to harness wind energy. Let’s see what comprises a home wind turbine and what those parts do. 

Wind Turbine

Small wind turbines come in two types; vertical and horizontal axis, with the horizontal axis being the more commonly used type. Two or three blades that are often made of fiberglass form the horizontal-axis turbine. Meanwhile, the generator, rotor, and tail are attached to the turbine frame. 

On the other hand, vertical-axis turbines consist of  2 kinds: Darrieus and Savonius. The Darrieus wind turbine has vertical blades and looks like an eggbeater, while a Savonius turbine is characterized by its S-shape design.

The amount of wind power a horizontal-axis wind turbine produces depends on the diameter of its rotor, which determines its “swept area.” This is how large an area the blades sweep, which is proportional to the quantity of wind it captures. 

Tower

When it comes to turbines that harness wind energy, the higher the tower, the more power the system can generate. That’s because the wind speed increases with height. Thus, a small wind turbine is installed on a tower to take advantage of greater wind speeds. 

Aside from exposing the blades to higher wind speeds, the tower also places the turbine above the air turbulence that can occur closer to the ground caused by obstructions such as hills, trees, and buildings.  

Two basic types of towers exist on the market. These are the self-supporting or free-standing type and the guyed, which is supported by wires. Each version of these tower types has a tilt-down version.    

Battery

A stand-alone home wind turbine is a system that’s not connected to the utility grid. This type of small wind turbine needs batteries to store the excess power generated during periods of high wind speeds. You can later use the stored energy to power your home when the wind speed goes down. The system also requires a charge controller to prevent battery overcharging.

Deep cycle batteries, like those used in golf carts, are designed to provide sustained power over an extended period and can discharge and recharge 80% of their capacity hundreds of times. This makes them excellent options for renewable energy systems. 

For safety, the batteries should be kept away from living areas and electronics because they contain corrosive and explosive substances. Lead-acid batteries should also be protected from extremes in temperature.  

Average Energy Production

If you intend to supplement your grid-sourced electricity with energy harnessed from wind power, you’ll need to size your system depending on your needs. The amount of energy a small wind system produces depends on several factors, such as the tower’s height, the blades’ size, the wind speed in the area, and the like. 

Small turbines that capture and transform wind energy into electricity range from 400 watts to 20 kilowatts. An average home in the US uses about 877 kWh per month (or 10,649 kWh a year). How significantly a turbine contributes to meeting your energy demands depends on the average wind speed in your area. 

For example, in a location with an annual average wind speed of 14 mile-per-hour (6.26 meters per second), a 1.5-kilowatt wind turbine can generate about 300 kWh a month.  

Types of Residential Wind Power Systems

You don’t have to live in a windy area to utilize wind energy for your home. In fact, some locations that enjoy a high average wind speed might not be suitable installation sites for a wind turbine. What matters more is choosing the type of equipment that will fit your situation and requirements. Let’s look at the kinds of wind power systems available to determine which will best suit your needs.

Stand-Alone Wind Power Systems

Also called an off-grid wind power system, this is a system that’s not connected to an electricity distribution grid. It’s most effective when situated in large, open areas, away from existing obstacles and turbulence. The top of a hill is the ideal site. Wide open spaces far from windbreaks, such as buildings or trees, often offer higher wind speeds which help maximize the benefits of wind energy. 

For a stand-alone wind power system to be worth your investment, your area should have an average annual wind speed of at least 9 miles per hour (4.0 meters per second). So while installing this type of wind power system in the city is possible, you’re more likely to have the required average wind speed if you live outside the city limits.  

Grid-Connected Wind Power Systems

You don’t need to go off-grid to benefit from energy efficiency. Even a grid-connected wind turbine can help with your goal as it will reduce the electricity you draw from the utility. A grid-connected wind power system may not be able to deliver all your power needs if the wind speed in your area isn’t ideal. Thus, the utility-supplied electricity will make up for the difference. Still, the contribution from your wind turbine is enough to lower your energy bills. 

Grid-connected systems are less expensive because you can install a smaller system than when you opt for a stand-alone turbine. Moreover, if the wind speeds in your area allow your grid-connected wind turbine to produce more energy than you consume, you may get cash incentives from the utility. 

Factors to Consider Before Getting a Residential Wind Turbine

Using renewable energy to power your home is an excellent way to reduce its environmental impact and lower your energy budget. Installing solar panels and wind systems can supply you with enough power for your appliances and lighting needs. In some instances, you can even enjoy energy independence if the electricity your system produces is sufficient for your requirements. 

With the country’s varied wind resources, installing a residential wind system can help you enjoy a reliable electricity supply. The power production of your system depends on several factors, so if you plan to install one, here are some considerations. 

Good Wind Resources

Even the most powerful wind turbine won’t produce usable power if there’s no wind to spin the blades. Thus, the prevailing wind speeds in your area are critical in determining if a wind system is the right renewable energy source for you. 

A wind turbine has what’s called a “cut-in,” or starting wind speed. It means that your wind system will not generate power until the turbine reaches the required speed. The starting wind speed ranges between 5 and 10 mph. Wind turbines also have a rated wind speed, which is the point where the wind system generates its maximum power. The rated wind speed is usually about 15 to 50 mph, depending on the turbine’s size. 

Installation Site

The installation site also influences how much energy you get from your wind system. Putting a turbine behind tall buildings or among a bunch of trees will naturally prevent the wind from spinning those blades at the required speed. Turbines should be installed in high areas with enough space to achieve maximum wind speed. Usually, they should be at a height between 25 to 60 feet to attain that. 

The ideal location for a wind turbine is an area free from obstructions within 250 feet to avoid turbulence created by trees, buildings, and other obstacles. Some turbine models can achieve maximum wind speed when installed in a body of water such as a lake or by the sea on a cliff face. 

Potential Legal & Environmental Obstacles

The last thing you want after spending time, energy, and money in mounting a wind turbine is to take it down because of complaints or legal technicalities. For example, restrictions regarding the height of the structures permitted in residentially zoned areas might exist in your locality. Also, your neighbor could complain about the turbine blocking their view or the noise it creates. Both situations could lead to a possible dismantling of your wind system.  

To avoid any hassles, check with your local planning department and any neighborhood associations for potential legal and environmental obstacles you could encounter in building a wind system. 

Tax Incentives for Wind Energy

Whether you install stand-alone or grid-connected systems, you stand to get tax credits for using a small wind system to power your home. In the country, small wind turbines qualify for a Residential Clean Energy Tax Credit associated with the cost of the wind system. The tax credit includes the purchase and installation expenses. The amounts for the prescribed periods are as follows: 

• 30% of the cost for property placed in service after December 31, 2021, and before January 1, 2033 
• 26% of the cost for property placed in service after December 31, 2032, and before January 1, 2034 
• 22% of the cost for property placed in service after December 31, 2033, and before January 1, 2035
