You need calculus to design a windmill or an auto engine or an electric motor beyond the "just sort of works" level. Most of analog electrical engineering is defined by calculus. Althogh, yes, you can get LTSPICE to do most of that for you.

You can get LTSPICE to do the simulation for you, but it will be much harder to understand why an interesting circuit works (such that you can adjust it or implement it with real components) without understanding some of the calculus behind the simulation.

Windmills are older than calculus, so that's just not true.

		Inefficient windmills are older than calculus. Efficient windmills need aerodynamic theory to calculate a good blade design. It's quite difficult to do that. It took several decades to scale up windmills. (A small wind turbine is like a propeller in reverse. A large wind turbine is not, because wind speed varies across the blade circle enough that those stresses dominate the design. It took decades to debug this, and make large wind turbines stable under high winds.)
