Why do modern windmills only have three blades?
The main reason was not yet given in any of the above answers.
It's the limit of the hub.
Each blade has to be attached. The attachment has to carry the four forces a) weight b) outward force due to rotation c) bending moment due to wind load d) torque = the force we really want to have.
So all this has to be strong and requires a good size.
Then each blade must have a mechanism to rotate the blade around its long axis to optimize the efficiency in various wind speeds. It even turns the blade to "feather" position to idle it in case of hurricane force winds.
It is not feasible to have enough space available to fit more than three such strong mechanisms into a small hub.
