Something else for the UK to be proud of. "The world's largest offshore windfarm, which cost over £750m to build, is poised to open off the coast of Kent, with 100 turbines producing enough electricity to supply heat and light for 200,000 homes." Normally wind power only contributes about 3% to our electricity supply but this comes at a time when the national grid confirm that in one 24 hour period at least 10% of the UK's electricity came from windfarms and 4% from hydro. "Maria McCaffery, chief executive of RenewableUK, said the figures underscored the contention that wind and renewables were no longer "alternative" but core parts of the power sector." www.guardian.co.uk/business/2010/sep/12/thanet-wind-farm-energy |

"at one stage last week 10% of the UK's electricity came from windfarms." says the Guardian.
Lazarus says " in one 24 hour period at least 10% of the UK's electricity came from windfarms".
Spot the difference between the two statements.
I would like to see the figures, please.
I take nothing on trust, unlike Lazarus, who stops reading when he gets to the conclusions he likes!

Oh I see, I supposed that you read it that 'for a 24 hour period' at least 10% of the UK's electricity came from windfarms. I apologise, I only meant to suggest that it happens during a day, not for an extended period, that is why I included the 3% figure. |

You've beaten me to it Marchesarosa, my point too:
I’m finding different reports about when this event occurred; some seem to be saying that it was “at one point” and that this point was at “8.30pm on Monday 6th September”.
Can you provide an accurate statement from a reliable source please Lazarus?.

There's a huge difference between "up to" and "at least" Lazarus.
Might I suggest the use of copy and paste to avoid such misquotes.
Are you sure you don't work for the BWEA?

Just to clarify my point above:
The Guardian stated:
"that over a 24-hour period up to 10% of electricity came from wind"
Lazarus stated:
"that in one 24 hour period at least 10% of the UK's electricity came from windfarms"
(The Guardian does also state as per Ms post:
"at one stage last week 10% of the UK's electricity came from windfarms.")

But the guardian and £azarus also failed to mention that the thermal stations had to keep burning in case the wind dropped....so no actual reduction in emissions.

I was going to suggest it happened from 3.15am to 3.30am one breezy morning! But thanks for explaining that it was not for a 24 hour period! How could it be?
Well done, gang. Another crock cracked.

Wind yealds about 7000 GWh per year out of a demand of 400,000 GWh. = 1.75%
7000 GWh would supply about 1.2 Million homes.
Supplying 200,000 homes from just 100 turbines sounds a bit optimistic.

Pumbles, now you raise it, yes I agree; by my admittedly rather rough calculations, the 100 turbines would each have to be 3.85MW, pretty large as turbines go and they certainly would not be onshore ones where 2MW are considered the max. |

A friend of mine has a 1MW wind turbine. He tells me it produces, on average, £80/day. I think he's on the 10p/unit tarriff since turbine was built a few years ago. It cost £800,000. So payback time is around 27 years. I asked if he'd been on the laughing fags.  You can see a rather pleasing picture of it on google earth. Look at Burray Island in Orkney. Zoom in on the Northeast part of the Island. You'll see a white squiggly road (motocross track) It's just to the north of that. |

Well done, gang. Another crock cracked. Hardly a crock. It was poor wording from me which I immediately apologised for. I never post about such things with out sources inviting all to check and it is good to see you have at least read the link. |
