Authorization for wind measurement mast?

[chatelot16]

a hill creates ancestry! fully agree ! but it doesn't necessarily make a good wind for a wind turbine at the top of the hill

on a flat desert or at sea we have good laminar wind at low height ... on a hill of 20m you need a mast of 20m more to have good wind

A good wind for paragliders is a good wind for wind turbines;)
A flexible sail is much more capricious than a pale wind turbine ... It is precisely the kelp that we are looking for in a paraglider!

After never being downwind it is valid in both cases, except that a wind turbine (unlike a paraglider) is installed (if the installation is not made by fun ... this is the case for example the gable wind turbine scam) to NEVER be downwind from the weather wind ...

I thought we had made a subject on the solar mountains but obviously not, so I just made one: energies-renewable / solar project-mountain-elioth-the-eolien-de-breaker to-valley-t14512.html

ps: don't forget to put an avatar please ... thanks ...

don't confuse Chamonix and Angoulême!

in the alps of large slopes and the weather conditions can produce wind, but it is not in the mountains that we see large wind turbines

in Angoulême there is no drop! there are just little hills that break the wind and make it pass higher

there are some large wind turbines and they are not installed anywhere: they are visibly installed where it is the flattest

I'm not just talking about Chamonix!

The slope breeze phenomenon is valid, obviously less strongly, for more reasonable slopes ... provided that the sun "hits" ...

Yes, current projects are mostly installed on the flat, because it is not only the wind that must be taken into account in an industrial wind turbine project: earthworks, access and (power) connection strongly prohibit or limit wind turbines projects on the ridges but if there was only the wind to take into account then all the wind turbines would be on ridges!

Although in the black forest there are many wind turbines on the ridges (some are visible from the plain of Alsace on the French side so ...)

Alsace is the poorest region in France in terms of wind ... however the peaks of the Vosges are there ... Is the German wind so different from the Alsace wind?
