Wind Turbine Payback in Wood County, OH

Wind turbine payback in Wood County

No. The turbine wears out before it pays for itself.

At 30 m, the height a home turbine tower usually reaches, the wind in Wood County, OH averages 5.93 m/s (13.3 mph). A 10 kW turbine there would make about 19,186 kWh a year, worth $3,609 at OH's 18.81¢/kWh. Against an installed cost of about $100,000, that is a payback of 28 years, and the turbine is built to last about 20.

What to do in Wood County

A home turbine is not worth buying for savings in Wood County unless your spot is far windier than the county average, 6.9 m/s at the hub against 5.93 m/s here. Per kW, solar panels would make about 1,121 kWh a year here against the turbine's 1,919, so get a solar quote first.

What would have to change

Against the rest of OH

Wood County is the 950th windiest of 3,144 US counties at turbine height; the national middle is 4.79 m/s. The windiest in OH is Lake County at 6.53 m/s, payback 23 years.

Month by month in Wood County

January is the strongest month here, at 6.82 m/s and about 2,190 kWh. August is the weakest, 4.50 m/s and 793 kWh, so the best month makes 2.8 times the worst. November to March brings in 52% of the year's output in Wood County.

What a taller tower would buy

Measured at 10 m the wind in Wood County averages 4.63 m/s; at 50 m it is 6.66 m/s. That gives a shear exponent of 0.226, typical of ordinary open country. Going from 20 m to 50 m takes output from 15,421 to 24,582 kWh a year, 59% more, before counting the extra cost of the taller tower. Why tower height decides it explains the shear behind these numbers.

2 of the 6 closest counties are windier at turbine height; the windiest, Sandusky County, averages 6.2 m/s.

Sun versus wind in Wood County

Wood County gets 3.84 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,121 kWh a year; one kW of the turbine above makes 1,919. This is one of the rare places where a kilowatt of turbine out-produces a kilowatt of panels, by 1.7 times. Panel output assumes an 80% system performance ratio. Wind or solar runs the same comparison for every county.

How this is worked out

Wind is NASA's Power climate record, the 2001-2025 average at 10 m and 50 m for the county's centre, carried to 30 m with this county's own measured wind shear and spread into hours with a Rayleigh distribution. The turbine is a generic 10 kW, 7 m rotor machine with 10% losses. Cost is $10,000 per kW installed with no tax credit, because the federal one ended in 2025. One county-centre number cannot see your hilltop or your tree line, so treat it as the starting point for a site survey, not a substitute. The full method and its weak spots are in how the numbers are made.
