Wind Power System Sizing Calculator for the USA

Is wind power right for you? Find out quickly with our wind power calculator. Simply provide the data requested and you'll instantly know how practical a wind turbine system would be for you.

Simply provide the information requested below. All links will open in a new browser tab or window.

#1 Determine the speed of the wind available in your area.

To determine the average wind speeds for your area, first perform a quick View of Nationwide Wind Speeds to determine if your geographic region has any wind energy potential.

If your area does have wind energy potential, you'll want to zoom in for a closer view of your state and obtain more specific data by selecting your state listing below:

Note: If your state is not listed, it is because there is insufficient wind data available at this time.

> Enter Your Potential Wind Speed: mph

#2 Provide Information About Your Power Needs

To help you estimate what size wind turbine will work best for you, you first must have an idea of how much power your home uses during a typical year.

It is necessary for you to get your electrical utility bills so that you can get your last years values of total KWH (kilowatt hours) used, or possibly review your most recent billing statement which may provide your monthly average which you can simply multiply by 12 to get the yearly use rate.

> I use KWH per year.

It will also be helpful to know what you are paying your current utility company for each kwh. To do this as accurately as possible and to factor in their varying time of day rates, volume rates, taxes and fees, it's best to simply take a current bill and divide the total amount due by the amount of kwh's used. This will provide you with the true amount you pay per kwh.

> I pay an average of $0. per KWH.

#3 Select the wind turbine size to meet your home energy needs.

The capacity of your wind turbine to generate eletricity is directly related to the diameter of its rotor. Most wind turbine manufacturers have this information available online.

To assist you in determining the size of wind turbine that would suit your needs, we have assembled a few basic types that fit most home needs. You can click any image to get more information.

When reviewing this data, please consider whether you are looking to offset your current electrical use by generating some of your own power or are looking to create all the power you generally consume... and quite possibly sell the excess to your utility company.

When satisfied with the choice, simply select the unit that most likely meets your needs.
