Do wind power generators work with centripedal force?

I know that the wind is what gets them moving.

But are there weights in the tips of the ‘windmill’ blades that keep them spinning?

Knowledgeable persons only, no rude responses or I’ll report you.

Centrifugal force is actually a detriment to a windmills efficiency. It forces engineers to make the pivots and blades heavier and more durable than actually needed for the intended purpose of the windmill. This is necessary to provide the strength to withstand the centrifugal forces on the spinning blades.

The blades work on the same principal as an airplane wing, except instead of the low pressure on top of the airplane’s wing providing an upward force or lift, the low pressure areas on the windmill blades provide a sideways force which causes the blade to rotate.
Any weights on the blades are for balance to minimize vibration and to ensure a long and dependable service life.
The wind, as you stated in your question, is surely what keeps them spinning, the weights add a certain amount of inertia between wind gusts, but that is not their primary purpose. The more weight, the more wind energy it takes to get them spinning up and performing their function inside the mill.
