In the fifties the ESB built two big dams on the river Lee. They flooded thousands of acres of land,roads and houses etc for good.Must have cost fortune at the time and the whole thing is considered a failure in terms of what power it generates. They also flooded Cork City badly a few times through its mismanagement. The whole thing was one big mistake.
We got the Gearagh wildlife sanctuary from it though. Something for the birds ! Good few swans and geese are happy enough about it anyway. Not to mention other nature of the after hours variety
They destroyed 90% of the Gearagh when they damed the Lee which is probably the biggest damage of all that the scheme did.We got the Gearagh wildlife sanctuary from it though.

Very controversial choice of words (almond milk alert).
Where are them wind turbines being put up? I see them passing west on the N22 some nights. The size of them is out of this world.
There is one wind farm in ballingeary/ renaniree area. alot of the locals think there are out of this world too ! Would love to get the real facts and figures of the ground work 'not sales spin'. 1 local person said 100 lorry loads of concrete per turbine. Havent heard how much rock breaking went on but all the usual tearing necessary involved to get into mountainy site
The ones here are 86 metre masts and 45 metre blades so topping out just under 130 metres, 20 loads of readymix in each base, each blade weighs 9 tons so a fair bit of momentum when 27 tons is rotating at 15 rpm, a bit of maths. 90m diameter x 3.142 = 282.78 circumference x 15 =4242 metres /min x 60 =254,520m/hr , 254 kmh/hr tip speed or 158 mph.
I wonder was 20 loads the figure qouted for getting planning purposes? Or else ground must ve been spot on. The the figure of 100 loads per turbine in ballingeary sounds alot more realistic from local info here. Would love to here final figures/costings when the job is completed
I would not think it was generating a huge amount of electricity but I think it is financially viable . The fisher men are always bellyaching about it but what is new there . It is an unusual setup in that it generates more power when the river level is low due to a bigger fall .
But that's still 400ish tons of concrete under the windmill
A long way short of the 2000+ suggested in a previous post, no denying wind turbines are carbon hungry, concrete, steel, cabling, transport, construction etc are all big consumers.
I thought @bagenal bought it as I was only poling it up for the vendor who is a big Tillage farmer.
I wish.
That may be what they are saying in public, but the massive advantage of an interconnector is the French supply of cheap clean (from a CO2 stand point) nuclear power. It is an Irish solution to an Irish problem. We want the nuclear power, but don't want it here.
A supplier was questioned on a local wind project here. Couldn t give final figure but said 1000 tons plus of concrete alone per turbine would be a minimum and very conservative figure back there..the wind company will always give low figures publicy for obvious reasons. They are trying to look envir friendly and get planning. I would be all for wind turbines if they could be successfully married to another system like hydro or gas.
How's the new tank coming along
It's watertight anyway
