A perfectly efficient blade would capture all the energy in the wind passing through it, which, sadly isn't possible in the real world. Physics, in the form of Betz's Law, dictates a theoretical maximum efficiency of around 59.

Transport of wind turbine blades, often exceeding 160 feet in length and weighing over 15 tons, demands rigorous compliance with U. Department of Transportation regulations, including securement rules under 49 CFR §393.

The tips of a modern wind turbine's blades can reach speeds of over 200 mph (322 km/h), although the actual rotational speed, measured in RPM (revolutions per minute), varies significantly depending on the turbine's design, size, and wind conditions.
