When building windmills, people think about how to increase their efficiency. In order to do that, they examine the parts. The most crucial parts of a windmill are, naturally, windmill blades. The very first thing to consider when talking about windmill blades is their number. The more blades a windmill has, the harder will be for it to rotate. The old ones used to have 4 extremely bulky blades. Many of them were use in grain grinding. Today, the most modern windmills have 2 or 3 blades. The length is significant too. If a blade is longer, it covers a larger surface when it rotates, so they can catch more wind with each rotation. This may result in additional torque. To protect the windmill blades we must not forget about their surface. If we provide them with effective maintenance, they'll last longer and will also be more productive. Also, the shape of windmill blades influences their rotation. There are a number of different shapes of windmill blades: the flat, rectangular types, the wing shaped types and the ones with both edges tapered to a slim line or both edges rounded like the ones of a plane wing. In case of the horizontal axis windmills, the wing shape has proved to be by far the most efficient one. The vertical axis windmills works very well with all the shapes of the windmill's blades, but optimum performance is given by the flat types and the ones with both edges rounded. About the material with which the windmill blades are made out of, if we think about the old ones, they were generally constructed from wood. Although those windmill blades are made of wood, their structure changed over time. They are lighter now so that they could spin quicker. An usual material that brings a high performance because of its sharp edges and its light weight is carbon fiber. One more material that is light, but also cheap is PVC. It is a synthetic material sometimes used for windmill blades. New substances are always being tested, in the hopes of finding a more affordable, more efficient solution. Windmill blades are continuously developing, although they appeared a very long time ago. At their early stages they were somehow inefficient, but people learned to develop them and to make the windmills a desirable source of energy. Many more shapes and materials have and will be for windmill blades and people begin using increasingly more this alternative source of energy which will not just save our money, but also our environment.
