Webb8 nov. 2024 · Wind energy, coincidentally, has a theoretical maximum efficiency of 59.3%, known as the Betz’ Limit. The best wind turbines reach about 95% of that, which is pretty awesome, but still isn’t that much different from a combined cycle gas plant. The wind is still free, however. Solar and wind have another factor which is important for economics.
