UPCOMING PROJECT

A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain, but the term is also extended to wind pumps, wind turbines and other applications. The term wind engine is sometimes used to describe such devices.

What is a Windmill?

Up until recently, people still only had visual impressions of what a windmill is, often associating it with the past and particularly before the industrial revolution. Today, things have come full circle, if you will and there is now a growing demand for large, technologically advanced windmills across the world. The term wind energy or wind power describe the process through which wind turbines convert the kinetic energy in the wind into electrical energy by the use of generator.

What this introductory guide seeks to do is describe the apparatus in laymana€?s terms and also outline how they work and what they were intended for originally and the purposes for which they are used today. We begin with a brief definition of what a windmill is.

  • It was originally a structure with sails, much like that on pre-industrial ships, and was originally used to produce flour from corn. In order to do this, the wind would have to prompt the sails to turn. They were also originally built by master craftsmen.
  • The dictionary expounds this definition further by relating it to a human physical exercise technique which replicates the symbolism and movement of the original windmill. It is also famously symbolic in Cervantesa€? classic of Don Quixote. This definition reminds readers that the original mill was also used to pump water and generate power.
  • In modern terms, the advanced windmill operates with just three blades mainly to generate sustainable sources of electricity and energy. Today, these windmills are also referred to as wind turbines.
  • According to Wikipedia, a€?A windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades.a€?

More from Wind energy: Fixed speed windmills run at one speed no matter what the speed of wind is and use gearbox (gearbox has gears which convert the slow speed of the spinning blades into higher-speed rotary motion) to generate electricity at the right frequency for the grid whereas variable speed windmills speed up and down as the wind speeds up and down

Main Purpose of Modern Wind Turbine

By now, most readers will know that modern windmills (turbines) primary purpose is to produce electricity from wind with as little impact on the environment as possible. These next few notes simply highlight this sustainable initiative. The minimal impact on the environment is, however, controversial. Wea€?ll mention this briefly too.

  • Whether located in rural or urban sectors, it is often people on the lowest level of the socio-economic scale that are faced with looking at these hegemonic structures every day. Also, nature lovers continue to voice legitimate concerns on how these turbines impact migratory patterns of bird species.
  • Already mentioned, the basic function of a wind turbine is to utilize the power generated from wind and convert it into usable (renewable) energy. On a smaller scale, home users can install their own turbine and produce their own power at little or no cost.
  • As renewable energy, it can be reproduced continuously until there is enough power to feed its designated locations. It is also promoted as a clean source of energy and while not yet widely used, it is ideal for the worlda€?s least developed nations as an affordable source of producing electricity.
  • Most importantly, the turbine contributes greatly to reduce fossil fuel consumption. It goes without saying that the more countries that use them, the greater the reduction in fossil fuel use because it has been proven to be a reliable driver of energy.

Positive Effects of the Wind Turbine

Finally, it is incumbent to emphasize the importance of wind turbines where environmental sustainability is concerned and as a rapid but highly effective response to global warming and climate change.

The exponential benefits are not only crucial but already evident where wind turbines are used increasingly, mainly in developed and developing nations. To finish this guide on windmills and its natural successors, wind turbines, we highlight some positive effects they have on humankind and the environment.

  • No more greenhouse gases Turbines do not emit carbon dioxide.
  • Power is free No government agency can presently regulate wind. So they cannot charge fees to those who choose to use it as an alternative source of life-sustaining and life-saving energy.
  • Versatility There is a perception in some areas that the only modern day wind turbines you are likely to see are giant monstrosities hovering over your home. Not the case, because smaller wind turbines, small enough and perfectly equipped, are being manufactured for you today. All you need do is talk to the farmers who are already utilizing customized turbines for their own agricultural needs.

Positively speaking, this may have been a whirl-wind tour of processes, purposes, features and just causes along with some historical anecdotes on ancient windmills and the modern day equivalent of the wind turbine. The main purpose here was also to stimulate increased awareness and interest in this important piece of humankinda€?s legacy for the future.
