I wonder how much energy could have been gathered recently if we had the technology to harness it, wind turbines are shut down in strong winds I think ?
IIRC Scotland gets about 40% of the entire wind energy that Europe sees. Unfortunately, as you're seeing, it tends to happen all at once.
The problem isn't really converting the energy, we can do that OK. Even if we converted all that wind energy (and you can't do that, physics limits you to about ten percent of it at best), nobody would want it all at once like that. The real problem is storing it.
Even in these days of high-fallutin' quad core processors, the best we can really do to store large quantities of energy is to pump water up a hill, and then when we want the energy back we let it run back down again.
"That sucks" you might say. Well it surely does.
Yes, they do shut turbines down when the wind exceeds their design ratings. If they didn't, the wind would destroy them. The power in the wind is proportional to the
cube of the wind speed. So if you design a turbine to produce its maximum rated output of one megawatt at, say, 20 knots (quite a stiff breeze which you don't get for much of the time, even in Scotland, and certainly not enough to warrant basing the turbine specs on it) then at eighty knots your turbine would be producing
sixty-four megawatts which would blow it to kingdom come if you let it even try. That's quite apart from considering things like tower, blade and bearing loads, blade flexing, vibration modes etc.etc.
It's a nice idea, and it's a small contribution, but basically wind power isn't the answer. I think it's more a political statement than a real attempt to solve any energy problems but I guess the moderators will step in if we go any further down that route...
