Electricity generated from windmills is called windmill electricity.  Windmill electricity is a very cheap source of energy in terms of generation of power. But that’s only once the windmill is installed. Many experts believe that windmill electricity is very cheap, in addition of having the advantage of being pollution free. They believe that it is a very good choice for farmers and small home owners as they do not require a lot of power for their needs. But you can’t generate windmill electricity constantly because wind is not always blowing at a suitable speed. Sometimes its speed is very slow and sometimes it’s very fast. So this might not work for people who require higher amounts of energy for their usage. You will mostly experience windmill electricity in farms and ranches.

The basic component in the mechanism of production of windmill electricity is wind force. What wind does is it rotates the wings of the windmill which moves the turbines that are fixed inside the windmills. When the turbines start rotating, they start producing energy and electricity which is used to run home appliances and light the house. The blades of windmills are most commonly made of fiber glass. The body of the windmill is usually made of steel and painted in dim gray.

Windmill electricity is normally produced away from the populated areas. You will not find any windmills installed in the commercial areas. That is because the size of the windmills is very huge and they can be potentially very dangerous in a busy area. Wind is a very basic factor in producing windmill electricity because in open areas, wind usually blows at a much faster speed than in the commercial populated areas. That is why this concept will work much better in farms and ranches than in a city like New York. The electricity production depends on the speed with which the wind blows. It also depends on the height of the windmill at which it is installed. The higher the windmill the more windmill electricity will be produced. Windmill electricity is renewable energy and it has an unlimited source that can be used over and over again.

While getting windmill is still not an option for people who live in the city, it certainly is one of the best options of people who live in the country. They ceased to be incredibly expensive a while ago, and they have the advantage that they will eliminate or reduce electricity bills. And they help save our world.

When building windmills, people think about how to increase their efficiency. In order to do that, they analyze the components. The most important components of a windmill are, of course, windmill blades.

The 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 rotate. The old ones used to have 4 very heavy blades. Most of them were use in grain grinding. Nowadays, the most recent windmills are equipped with two or three blades.

The length is important too. If a blade is longer, it covers a larger surface when it rotates, therefore they can catch more wind with every rotation. This may lead to more torque. To protect the windmill blades we mustn’t forget about their surface. If we provide them with efficient maintenance, they will last longer and will also be more productive.

Also, the shape of windmill blades influences their rotation. There are a few different shapes of windmill blades: the flat, rectangular ones, the wing shaped ones and the ones with both edges tapered to a thin line or both edges rounded like the ones of an airplane wing. In the case of the horizontal axis windmills, the wing shape has proven 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 the best performance is given by the flat ones and the ones with both edges rounded.

Regarding the material with which the windmill blades are made from, if we think about the old ones, they were usually made from wood. Even though those windmill blades are made of wood, their structure changed over time. They are lighter now so they can spin faster. A common material which brings a high performance due to its sharp edges and its light weight is carbon fiber. Another material that is light, but also cheap is PVC. It is a synthetic material often used for windmill blades. New materials are always being tested, in the hopes of finding a cheaper, more effective solution.

Windmill blades are constantly developing, even though 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 desirable source of energy. Many more shapes and materials have and will be for windmill blades and people start using more and more this alternative source of energy that will not only save our money, but also our environment.
