A typical modern turbine will start to generate electricity when wind speeds reach six to nine miles per hour (mph), known as the cut-in speed..
A typical modern turbine will start to generate electricity when wind speeds reach six to nine miles per hour (mph), known as the cut-in speed..
It’s not the speed, but the consistency of wind that produces the most wind power. Wind turbines will generally operate between 7mph (11km/h) and 56mph (90km/h)..
The quick answer to the first part of this question is:Small wind turbines spin at up to 100mphLarge turbines spin at up to 180mph.
The short answer is that if they move slowly, they produce less power. But if the wind speed doubles, then a windmill could produce eight times more power under the appropriate conditions. [pdf]
