Hydraulics, a false good idea?

Renewable energies except solar electric or thermal (seeforums dedicated below): wind turbines, energy from the sea, hydraulic and hydroelectricity, biomass, biogas, deep geothermal energy ...

Obviously there is everything else ... I just wanted to say that it was surely not the small hydro mills that were causing harm to the aquatic fauna ...

There is no quick fix, only compromises.

Have you seen the "madness of men"? It's not about fish but dams and "big idiots": https://www.econologie.com/la-folie-des- ... -2495.html

Hello

Normally when we make a dam, we make a fish pass
some place is a salmon winder.
Almost all of Quebec's electricity comes from large dams.

A pass for a unique kind of endangered fish
the Copper Redhorse .. so that it circulates on each side of the dam.

it's obvious !
we are a bit of a stranger on this planet and it doesn't have
need us to "be" ... moreover she has already "been" ... without us.
many other species are much more essential than us, the little bees for example.
therefore any energy solution can only be a compromise.
I believe, like many others, that local solutions
are essential, whether solar, hydraulic, geothermal
we can always equip a dam, it will never know as well
although without dam, you just have to change your way
to see things and give less importance to the "dough" side
of the case ...
you who dig Canadian wells, did you think of
moles? : Cheesy:

And it will surely be without us also to complete your reasoning ... But sorry but I do not see how the man would be, by birth, a less honorable species than the others !!!

It is OUR western (but also eastern: japan, south east asian, china and india ...) societies of overconsumption that do not respect their environment or little (however essential to life) not man in itself!! This is not the case for all men on earth, some "tribes" still live in perfect harmony with the planet ... but our society makes them look like ... savages! While they are probably wiser than us on many points! Here it deserves a new shite!

Fallacious for the time, the argument seems to me today much more valid given all the rest, of course!

And for the big one ... well yes I think you're right (unless a bunch of eco-terrorists blow it up!).

Good night!


voui voui i see ......

and if not where did the turbines that were removed go?

to say that before all the villages were autonomous with their local electrical production!

to return from there to the disappearance of the fish, it is to blind oneself not to recognize that the chemistry contributed for much there, with the absence of prohibition to discharge everything in the water courses in "all at the l 'sewer' as has happened everywhere ...


then all that compared to local electricity production, it joins wind turbines and should be mandatory ...

in the series "you want current"? -)

Hello!

But, there were no turbines! It was grain mills ... as Christophe said. We've converted them to µcentrals since then, that's all.

Yes, Jonule okay! But like all complex problems, there is no one cause and one solution. I am also convinced that chemical pollution has been "potentiated" by "physical" pollution (storage of effluents in the sediments trapped upstream of the structures).

then all that compared to local electricity production, it joins wind turbines and should be mandatory ...

in the series "you want current"? -)


Mandatory ! Ah but NO! We must let the people concerned decide in their soul and conscience .... Otherwise hello the "green" dictatorship. Personally I prefer to live more "roots" and be able to go fishing and eat my catches with my family ....

The central idea is that anyway, our current energy expenditure (for our techno-military-commercial civilization) is not sustainable in the long term and that therefore we must review our consumption standards down ...

So, believing that we can maintain ourselves at the current level (or even just a little lower) with µcentrales and other wind turbines or even PHRSD is, in my opinion, an act of faith and not an objective analysis of the situation.

Good day to all !

Hum! I come back quickly on this post.

It seems to me (to verify) that the arrival of man on new continents for him each time took place according to the same scenario: Population explosion, disappearance of large animals, major ecological changes and taking collective awareness of the damage committed in the form of spiritual precepts .....

Well, that hasn't worked with us (yet?), But I think it will inevitably come (see La belle verte). The question is when? and after how many major ecological disasters? Because obviously, the more we "wait", the more difficult and traumatic it will be.

well the turbines of the micro power plants where did they go?

someone has taken them all off, until everyone forgets that there were!

except the old ones, to bet ;-)

: Cheesy: Definitely, it's a hobby!

"We" did NOT take them all off those turbines! There are still many in operation. (see Castorbarbu's post earlier in this same subject)

ah!
OK!

no i was not talking about mechanical turbines, but electric generators!

of course !

so "they" would have left the turbines, but not the generators?


it would be nice to find a period document!
