what's happened to your idea of opening all the pits back up :rolleyes:

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

We could do that as well, as long as it involved carbon capture and clean coal

With the locations used for wind turbines, it is very rare that there is no wind. Also they usually generate more than is needed to allow for any drops at one site.

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

Ironicaly they will always be suceptible to wind though ,they work between speeds of 10-30 mph when th ewind gets upto 40-50 mph they have to shut down requiring back up stations to generate for them

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

If that was the case, then I doubt that there would be so many on the top of the hills in the middle of the pennines, or off the coast, as both areas often experience far higher wind speeds.

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

It is the case ,that's why in medium to high winds you will never see a wind turbine turning .It's logical realy because if you think about the speed that the gears and generator inside the nacelle will be turning with a max speed of 30mph wind speed they would just burn out ,and then think about the g force at the tips of the blades they would tear apart

There's a interesting report here about accidents involving wind turbines one of the biggest problems is blade failure.

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

Cut-out speed is typically 55mph, apparently ...

The thing to understand about Green policy is that it is essentially anti-development. They moan about renewables as much as they moan about fossils because renewables still allow the possibility of a continuing increase in energy consumption and economic output. I wouldn't pay an excessive amount of attention to them. Society has always had luddites and always will.

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

To tell you the truth I don't know. Maybe that report is talking about early models, because I've seen some turning in very high winds.:confused:

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

You know, about 3,000 years ago the elites of the ancient societies of the Middle East were engaged in a strikingly similar discussion about the relative merits of bronze and iron.

Bronze was seen as a superior material; it was harder to come by than iron, which was to be found just about everywhere, but nobody had quite mastered the efficient use of iron in making anything you might actually want to own (such as a really good sword, or a nice sharp-tipped spear).

Unfortunately, tin, a key component of bronze, is not to be found everywhere. It had to be brought great distances by hazardous sea routes. Its supply was vulnerable to disruption. Such disruption is most likely what led to the switch to iron - much as people wanted to go on using bronze, the raw materials became too rare and expensive.

Three millennia on, and necessity has once again been proved the mother of invention. We are extremely good at using iron as an ingredient in all sorts of stuff you wouldn't want to try to use bronze to make. In fact, try to tell anyone that there was a time when iron was considered too troublesome to bother using at all, and you might get a quizzical or disbelieving look in response. But now it's oil and gas, the key raw materials of our energy-hungry economy, whose supplies are limited and vulnerable.

The point ... our current renewable technologies are in their infancy. wind turbines are big and not very efficient. But if we don't build them and learn from them, that's all the technology will ever be. We need to be brave and, I believe, take as given that if the human race is still here in another 3,000 years, they will find it bizarre and ever-so-primitive of us that we would ever have wanted to hang on to fossil fuel power generation instead of exploring the alternatives.

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

No it is a fact ,there are serious limitations with wind turbines in high winds simply because of the enormous stresses generated even at operational speeds .That is not to say they don't serve a purpose though ,they can supplement a small percentage of the national grid but will never replace traditional power stations as nuclear generation can do and it is very short sighted of any government to think so

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

Which is why we need to explore alternatives, like wave pawer, tidal power, geothermal, etc...

Do you know how much of the UK could be made uninhabitable by a disaster at one of our nuclear power stations? Where would the population from that area go??

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

Indeed we do need to explore alternatives i agree ,but we need new sources of power generation now not in 20-30 yrs or more .Actually we needed it 20 yrs ago but the governments of the time didn't see the urgency .Serious research should have been done on tidal ,wind ,solar, etc long before now and maybe then we wouldn't be stuck with a half developed technology that cannot generate our power requirements and we wouldn't be faced with the risk vs reward choice we now face with nuclear power.I agree that a accident on the scale of chernobyl would be catastrophic for the UK but ,because of our shortsightedness we have have i feel left ourselves with no other choice .

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

Apart from the fact that we still have plenty of coal

Re: UK nuclear plans 'put energy in French hands'Government plans for nuclear power r
 

which is getting harder to get as this proves

There were loads of pits that were closed down by Maggie, that still had loads of coal left.

She destroyed the British coal industry because she wanted to destroy the NUM.
