Factors to keep in mind while Building a Windmill
The most important things to keep in mind while building a windmill are
The energy of the wind is usually on the higher side and is more useful to generation of energy on the seashores or at the sides of large lakes or water bodies thus making these places ideal for setting up of a venture. Areas with wide terrains and no surface features, i.e. flat grasslands and such like terrain also has a lot of wind energy potential and that can be harnessed successfully
The wind characteristics also to be taken into account while building of a windmill are:-
1) The mean of the wind speed and all its variations occurring seasonally.
2) The distribution of the wind speed and the winds. The wind speed should be high so that the distribution is the same at all the points of collection of energy.
3) The height is also very important as the wind cannot be afforded to be too high or too low as then it become a difficult energy to harness, also the wind energy too close to the ground is less than the energy higher up, but the stability of the infrastructure higher up always has a question.
4) The frequency of gustiness should be avoided as they are usually harmful.
5) The general direction of the wind should be the same and should change direction only infrequently.
6) The density of the air should be another concern, because the denser the air, the more harmful it is for the windmill.
7) If there is a catch to the trade winds then it is specially beneficial to the windmills and energy production.
Terrain Characteristics
once the location for a prospective windmill has been decided upon, other requisites, different from the wind criterion have to be met. These are consisting of:-
1) The terrains must be in all a flat terrain, because the elevation difference between the terrain and turbine site is not more than 60 meters for a radius of 12 km.
2) All hills have to have a small height to width ratios: h:l must be < 0.016.
