When building windmills, people think about how to increase their effectiveness. To do that, they examine the mechanism. The most important parts of a windmill are, obviously, windmill blades.

The very first thing to take into consideration when talking about windmill blades is their number. The more blades a windmill has, the harder will be for it to work. The old ones used to have four extremely bulky blades. Most of them were use in grain grinding. Today, the most recent windmills have two or three blades.

The length is important as well. If a blade is longer, it covers a bigger surface when it rotates, so they can catch more wind with each rotation. This may lead to additional torque. To protect the windmill blades we mustn't forget about their surface. If we provide them with effective maintenance, they will last longer and will also be more productive.

Additionally, the shape of windmill blades influences their rotation. There're a number of different shapes of windmill blades: the flat, rectangular types, the wing shaped ones and the ones with both edges tapered to a slim line or both edges rounded like the ones of an airplane wing. In case of the horizontal axis windmills, the wing shape has proven to be by far the most efficient one. The vertical axis windmills works 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.

Regarding the material with which the windmill blades are made out of, if we think about the old ones, they were usually constructed from wood. Even though those windmill blades are made of wood, their structure changed over time. They're much lighter now so that they could spin faster. An usual material which brings a high performance because of its sharp edges and its light weight is carbon fiber. Another material that is light, but also economical is PVC. It's a synthetic material sometimes used for windmill blades. New substances are always being tested, in the hopes of finding a cheaper, more efficient solution.

Windmill blades are constantly developing, although they appeared a very long time ago. At their beginnings they were somehow inefficient, but people learned to develop them and to make the windmills a desired source of energy. A lot more shapes and materials have and will be for windmill blades and people begin using increasingly more this alternative source of energy that will not just save our money, but also our environment.
