How does wind spin those giant turbines? It seems like even high-speed winds wouldn’t move it very quickly with how heavy the turbine blades must be.

Already answered, but as a side note, wind carries an incredible amount of energy. You can feel the force on your hand (which has a very small surface area) when you stick it out the window of a car at highway speeds. I sail catamarans and you can easily break the rigging if you don’t reduce sail quickly when the wind picks up. The blades of those large turbines are around 40m so the surface area is huge.
