RE: Have you ever wondered why wind turbines have 3 blades
You are right on that one. Wind turbines although they have been around for long, unfortunately do not have popularity as the solar panels. I guess one reason is because wind is quite unpredictable or not so reliable as the sun. What do you think?
In Nigeria, we have little wind compared to other countries. But what we lack in the wind, we have it triple in the solar insolation :)
