July 21, 2025 EEVblog 1696 – TUTORIAL: Wind Power 101
A short tutorial on the maximum efficiency and power you can get from a wind generator. Also applies to water turbine generators.
Also deriving the industry standard wind power formula from first principles: Power (W) = 1/2 x ρ x A x v^3
Don’t let any wind power marketing scams fool you, you canna’ beat the laws of physics Captain, or Betz’s Law.
