How it helps
Use it for a focused task
This page helps you estimate real-world energy output from a small wind turbine before you spend money on equipment. Pick a rotor size, enter your average wind speed or choose a US region, set your tower height, and see estimated monthly kilowatt-hours.
The results panel compares that output to common household appliances so you can picture what you could actually power. Below the calculator you'll find explanations of the math, common mistakes people make when sizing a turbine, example scenarios for different property types, and answers to frequent questions.
Start by selecting a rotor diameter from the common DIY sizes listed, or enter a custom diameter in feet. Next, either type your average wind speed in miles per hour or pick a US region preset to auto-fill a typical value.
