The Windmeter measures wind strength at the player's position when right-clicked. If a Wind Mill or a Wind Turbine is right clicked, it will instead provide the effective wind strength for the given generator, accounting for obstructions around it. This can prove useful for finding why a Wind Turbine is not spinning. Low wind speed is highlighted by having too many obstructions for the current wind, due to the variable nature of the wind this may not always be the case. Blocks completely blocking the rotor, or neighbouring turbines that are too close have a differing message to allow telling the situations apart.
