Hopefully! The key requirements for a wind turbine are wind, adequate ground space (half an acre or more) and zoning laws that allow a structure at least 40-50’ tall.
Residential wind turbines are smaller versions of the wind farms you see all over the coutnry. They are incredibly and therefore do not require regular maintenance. They operate automatically and are designed to work smoothly for over 20 years.
Wind turbines convert wind into electricity. The blades of a wind turbine are attached to a rotor/shaft that generates electricity when it spins. For most wind turbines the process of generating energy is identical to the alternator in a car – electromagnetic induction.
For residential wind turbines, about 10 mph is required to start generating electricity.
No. Your wind turbine will provide electricity into your home just like your utility company provides you electricity. Of course, you have to pay your utility company – you don’t have to pay for your wind power.
Small wind turbines make about as much noise as an average washing machine. They are difficult to hear over the wind itself unless they are in very close proximity to your home. Wind turbines do not interfere with TV reception.
Generally, the wind tower is 30-60’ tall. In some cases, they can be taller.
Most single family residential homes have wind turbines rated for 5-10kW.
How much did you pay for electricity last month? As a rule of thumb, assume that a wind turbine will account for 70% of your electric usage. So if you spent $200 last month, you might save 70% or $140 each month. That’s a savings of $1,680 per year. Don’t forget that electricity costs have historically gone up 2-3% each year – that’s means you will saving about $2260 on your 2020 electric bill! Some wind turbines save more, some save less, but you are guaranteed to have a lower electrical bill from the day you install your wind turbine.
It depends on the size of your system. One thing is certain – wind turbines are much less expensive than they used to be. The rebates and incentives offered by the US government and most states can cut the cost of the system by nearly 50%. These rebates and incentives will not last forever, so it’s important to take advantage of them before they expire. For most single family residential homes your wind turbine may cost you $6-20K after all the rebates and incentives.
This depends on your electric bill, your location, your current utility rates and other factors. Many new systems pay themselves back in 5-10 years.
Some wind turbine installers provide financing options. Many homeowners have taken out a home equity loan to finance their wind power investment.

There is a 30% federal tax credit that is applicable to nearly everyone in the United States. Talk about a sale – 30% off your new wind turbine thanks to our government. Many states have additional rebates and incentives. These rebates and incentives can reduce the cost of your system by nearly 50% but they won’t last forever. Our advice – take advantage now.

Now is the right time for a couple reasons. The existing rebates and incentives are too good to pass up. In many states, the rebates go down over time and eventually expire.
Most importantly, the longer you wait, the more money you keep throwing away on electric bills. Do you want to keep paying $100, $200, $300 or more per month to your utility company? Probably not!
No. Your wind turbine provides the exact same type of electricity that your utility company does.
If you already get electricity from a utility company, then you can (and should) remain tied to the utility grid. This means that any electricity you need that is not generated from your wind turbine will come from your utility company.
In most cases, if your wind turbine generates more electricity than you are using then your meter will run backwards and you will get credit for the electricity you produce!
This is the most common method of installing a residential wind turbine system. A “grid-tie” system means that you are connected to both the utility and the wind turbine. This is the most common way to install a wind turbine as the utility can provide energy when your system is not producing (e.g., when there is no wind).
In many states, including California and New Jersey, your property tax will not increase. Another great reason to invest in a wind turbine!
Most wind turbines have a 5-10 years manufacturer’s warranty.
Battery back-ups are only recommended for homeowners that are not connected to an existing utility grid. Generally speaking, however, battery systems are expensive and not recommended for homes that have access to the utility grid (i.e., “grid-tie” systems) – this is the case for most homeowners.
Small residential wind turbines do not require regular maintenance. They operate automatically and are designed to work smoothly for over 20 years. Many wind installers provide options for additional maintenance guarantees.
It depends on where you live. You need to make sure your zoning laws allow for a structure at least 30-50’ tall. Your wind installer will generally help you take care of this.
