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.

To put that into perspective, consider this: it takes about 6 tons of coal to produce 7200-kWh, which would be required to power one home for a year using 10 kW of solar panels.
