If you live in an area exposed to wind, for instance, in a hilly area, a small wind turbine can help you shed up to 90 percent of your electricity bills. Wind power is one of the most cost-effective and environmentally-friendly ways of producing electricity at home. You can produce electricity with zero emissions and no pollution at all.
Besides the monthly cost of electricity, a small wind electric system helps you avoid the high cost of extending power lines to a remote area – and all you need is wind in your area. Besides, you will not be affected by power outages in your area, seeing as you produce your electricity.
People in urban and rural areas can benefit from a wind turbine. A small system not only lights your home, but can also be used for other applications such as water pumping in farms and ranches.
How do These Systems Work?
Simply put, wind turbines turn the kinetic energy of wind into electricity. The system consists of blades, a rotor, and a generator. As the wind blows, it spins the blades. The rotor captures the kinetic energy of the wind from the blades and converts it into a rotary motion that drives the generator.
Most of the modern wind turbines on the market have an automatic system that protects the rotor from spinning out of control in strong wind areas. You can connect your small wind system to the mains electricity grid, or you can have it stand alone. If you produce more electricity than you need at home, why not sell some and make some money? If your neighborhood is not connected to the electric grid, a small wind electric system might be a great choice.
Below are our reviews of the top wind turbines for home use.
1. Missouri 2000-Watt General Freedom II Wind Turbine
This Missouri wind turbine comes with a 50-year guarantee. You do not have to paint it or perform any special maintenance. Over the 50 years, the blades stay in operation, they will not rust, thanks to the fact that they are hot-dipped galvanized.

Why Do You Need a Residential Wind Turbine?
The move towards clean energy and a cleaner world is gaining traction. Everywhere around the world, governments, non-governmental organizations, international organizations, and even corporations are pushing for cleaner power in homes and in businesses.
Solar power has, for a long time, found its place in many homes. Although most people are still connected to the grid, solar and other cleaner sources of power complement the power from the grid. Wind turbines have their benefits:
• The power is clean and renewable: You only need wind to generate electricity with a small wind generator. The wind is abundant, and you do not need to destroy the land or exploit natural resources. The wind is always present, and you will, therefore, never run out of power.
• Cut power bills: Once you have installed a wind turbine, there are no extra power costs. You can produce enough power for your home, depending on the size of the turbine you choose. Larger wind turbines can even power more than one homestead. If you produce enough power, you can disconnect from the main grid and escape bills for good.
• Simple Installation: Most of the kits feature 5 or fewer components that easily connect. Residential wind turbines are small and most even connect to small poles on top of your house. Manufacturers offer all the installation materials, so, all you have to do is follow the manual. Depending on the model, you can install a wind turbine in an hour or less.
• No Pollution: Wind turbines do not produce smoke, smells, or chemicals in their operation – zero pollution. Most units do not even vibrate or make noise.
What if the wind Doesn't Blow?
Most homeowners are concerned about what will happen if the wind stops blowing. It can be devastating that just when you disconnected from the main grid, the wind stops blowing as hard in your area. Some periods throughout the year, the wind will not blow as strong as you'd want. Does that mean that you have to reconnect to the grid?
If you're going to have power every day, you can use your wind turbine in conjunction with a solar panel. Even if you live in a high wind speed area, there are days the air is calm. Besides the solar panel, you can buy large capacity batteries that will store power for you to use later.
When shopping, ensure that you pick a wind turbine that operates even when the speed of wind is as low as 2mph. This way, even a breeze can charge your batteries.
Pre-Purchase Considerations
How do you know you have the right residential wind turbine? You should go for the best affordable device to ensure your home has enough power at all times. For the most part, your home power needs will determine the unit you go for.
• Height Restrictions: Most manufacturers recommend that you install the wind turbine at least 20 feet above any obstructions. However, many neighborhoods, especially in urban areas, have height restrictions. If you live on a farm, you can install the unit as high as the manufacturer recommends, but that cannot happen if you live in the suburbs or an urban area. You can check with the local courts, neighborhood associations, or zoning committees, the highest you can place your wind turbine.
• Where to Mount: Determining where and how to install a wind turbine will help you choose the best options for you. If, for instance, you need a vertical wind turbine, you need to ensure that you have the space for that. However, if you are pressed for installation space, you can install the unit on top of your roof.
• Power Output: How much power do you need and what is your budget. Most residential units offer between 500W and 2000W power output. If you need a system that complements other power sources, or you live in a small cabin, you can pick one with 500W output. However, if you are not connected to the main grid and you rely solely on wind power for energy, you need to pick the most powerful unit, and that is the 2000W wind turbine.
• Safety and Durability: Does the unit you are going for have over-speed and over-charge protection? These two features protect your battery, the generator, and the blades. Besides, the unit should feature quality construction to last long. No one wants to spend top dollar on a unit that will break after a few months.
• Warranty: Some units come with a promise to serve you for more than 50 years, but that is not as good as a warranty. If you can get a unit with a lifetime warranty, that would be the best. However, aim to get at least 3-year warranty for a wind turbine.
• Buy from a reputable company: Buying from a reputable company guarantees you the availability of service parts, good customer support, and reputably quality products.
You should also check whether the unit can generate power from a breeze. Generators with a low torque can produce power even when the speed of wind is 2mph.
Are There Drawbacks to Using Residential Wind Turbines?
Even when you are connected to the grid, there are always a few drawbacks. For instance, if you are connected to the main grid, you will have power almost all days, but you will have to pay for that every month.
The wind turbine is the same; you get what you pay for. Low-cost wind turbines have come a long way and they have more features than they did a few years ago. However, these units can be very problematic for you. If you look at the warranty details of these low-cost units, you will see that the warranty may or may not be valid when your system breaks down.
You might want to stay away from turbines that appear on approved lists for rebate programs. Such products are from manufacturers who test and rate their products, giving them very high ratings. Note that, wind turbines will not last as long as solar panels; you will constantly need to replace parts
Wind turbines are almost maintenance-free. However, you need to inspect them annually or bi-annually to ensure they are always in top shape. You do not have to call a professional to maintain your unit as long as you have a few handy tools at home.
Lastly, you might not have power when the speed of wind is low. This means you need another source of power to complement, or large capacity batteries to carry you through the wind-less period.
Will a Wind Turbine Work in Your Home?
As long as you live in an area that experiences moderate speed of wind throughout the year. If you live in an area with so many obstructions, forget about a wind turbine. The U.S. Department of Energy recommends that you should be living in at least an acre to make the wind turbine efficient and avoid running into problems with homeowner's associations.
People living in suburbs will have challenges installing a wind turbine, thanks to the zoning requirements and other restrictions. Once you have ensured the restrictions do not block your efforts to have a wind turbine, and you are in an area with enough wind, you can go ahead and install a wind turbine.
Wind turbines come in handy to people who live in remote areas and are not connected to the grid. They are also ideal for people who need to cut bills and people who are conscious of the environment by producing clean energy for home use.
Conclusion
Whatever reason you may have to want a wind turbine, it is valid. A wind turbine will not only save you money, but will also help you reduce your carbon footprint. Understand that you do not have to use the wind turbine electric generator as the primary source of power in your home. You can install a wind turbine to complement the power from the grid or from your solar system.
Some people install a wind turbine to provide power in case of an outage, or to light the home and reduce bills. If you use a wind turbine to light your home and the power from the grid for other energy needs, you will have lower bills. For homes that use solar energy, a wind turbine comes in handy when the sun doesn’t show up and you need energy.
You can also use the residential wind turbine as a standalone unit, especially if you live in an area with no connection to the power grid. Again, if you find the cost or connection to the power grid to be unaffordable, you can result to a wind turbine. If you are using it as a standalone system, ensure you get the best quality with a high power output to keep your home lit at all times.
Some wind turbines are less costly, but they may not generate enough power. Some generate enough power, but they are very costly. Shop according to your budget while ensuring you pick the best affordable system for your home needs.
