The latest high-efficiency turbines are impressive machines. In 2016, when EDF Bouchain deployed a high-efficiency H-Class turbine in a combined-cycle configuration—meaning it recovered waste heat to drive a steam turbine, instead of venting it into the atmosphere—the plant achieved 62.22 percent net efficiency, according to GE Power.

In most all cases, the efficiency of the wind turbine depends on the actual wind speed. For the three blade design the efficiency curve looks like this: The maximum efficiency of 44% is reached in a 9 m/s wind (18 mph) and falls sharply at higher wind speeds. For a reasonable range of winds, the average effiency is around 20%,
