As I suspected - pedantics not science Suspected? Well, you are really quick! Of course I was referring to the abuse of language - that is qute clear from my first posting. |

"Current transmission connected renewable generation: 4,950 MW" Gosh, only 24,150 MW to go! |

At 25% load factor.
100,000 MW to go!
Dammit!

There is some confusion about the level of subsidy paid to wind turbine operators. Opinion seems to vary quite considerably. I have a suspicion that in the weird world of renewables they count a MW/hr as 100Kwhrs. It's the only explanation I can find. I know all about the feed in tarrifs for smaller turbines but the ROC's are strange. 1 ROC is worth about £45 but many of these bigger turbines receive 40 - 50p per kWhr?  ? What's that all about? |

At 25% load factor. 100,000 MW to go! Dammit! The irony of the whole situation is that the targets are for installed capacity, not output. The 'poor' load factor of wind turbines is conveniently ignored as far as the targets go although obviously the ROCs payments are affected by the load factor. |

"One ROC is issued for each megawatt hour (MWh) of eligible renewable output generated." "Suppliers meet their obligations by presenting sufficient Renewables Obligation Certificates (ROCs). Where suppliers do not have sufficient ROCs to meet their obligations, they must pay an equivalent amount into a fund, the proceeds of which are paid back on a pro-rated basis to those suppliers that have presented ROCs. The Government intends that suppliers will be subject to a renewables obligation until 31 March 2037." |

"Every wind turbine has a magnet made of a metal called neodymium. There are 2.5 tonnes of it in each of the behemoths that have just gone up to spoil my view in Northumberland. The mining and refining of neodymium is so dirty (involving repeated boiling in acid, with radioactive thorium as a waste product), that only one country does it: China. This year it flexed its trade muscles and briefly stopped exporting neodymium from its inner Mongolian mines. How’s that for dangerous reliance on a volatile foreign supply?"

Marchesa The sad thing is that many that support wind energy were the very people who were against nuclear. Had they not been so effective in their campaign, I am certain that by now we would be using thorium as a nuclear fuel in what would have been our "state -of-the-art" nuclear power stations. Just another example of the green movement shooting itself in the foot and of the dangers of running around like headless chickens to pacify such people.  P BTW: Do you sleep during the day or are you an early riser? As your posts seem to be posted at some pretty strange hours! Has anyone else noticed that the clock on this website uses CET and not GMT? |

I am busy and pre-occupied with a conversion project at the moment, principled, so I have had to deprive myself of the pleasures of doing climate duty! My sleep patterns have changed a bit lately, too. and I sometimes wake up at 2, 3 or 4am. Often I have a look at the climate blogs to see what's going on and I may make the odd comment here.
It's quite a long time since I was engaged in doing and overseeing practical work and the change from message-boarding is welcome. One can get addicted!
Board time is one hour ahead of us at the moment. I suppose that's a slight improvement on one of the US time zones!

Trent Brome writes on his Facebook page: Arlington, WY – avg annual wind speed of 31mph, gusts above 110mph, seems like a great place for a wind turbine ….right?   Photos from Feb 1, 2011 as the cold air mass that formed Snowzilla barreled through. The wind chill in the area from yesterday was extreme, -54F !! Combine cold temperatures that make steel brittle along with gusty winds, and you have a Titanic recipe for disaster. For those that will argue that I’m being unfair to the promise of wind power, I welcome you to provide photos of any power plant in the USA that has been collapsed due to weather. Downed power poles sure, but power sources? h/t to Eric Nielsen for the photo wattsupwiththat.com/2011/02/02/wind-power-gets-bent-out-of-shape-in-wyoming/#more-33030------- I welcome you to provide photos of any power plant in the USA that has been collapsed due to weather, challenges Trent. Coal frozen in the power station hoppers, perhaps? Natural gas pipeline valves frozen? |

C ustomers face huge bill for wind farms that don't work in the coldBy TOM MCGHIE Last updated at 1:20 AM on 9th January 2011 Jeremy Nicholson, director of the Energy Intensive Users Group, which represents major companies employing hundreds of thousands of workers in the steel, glass, pottery, paper and chemical industries, said the failure of wind power had profound implications. He was speaking after new figures showed that during the latest cold snap wind turbines produced less than two per cent of the nation’s electricity. Now Mr Nicholson predicts that the Government will encourage power companies to build billions of pounds worth of standby power stations in case of further prolonged wind failures. And the cost of the standby generation will be paid for by industry and households through higher bills – which could double by 2020. Industry regulator Ofgem has already calculated that the cost of achieving sustainable energy targets – set by Brussels but backed by the British Government – will amount to £200 billion, which will mean that annual household fuel bills will double to about £2,400 on average within the next ten years. In the last quarter ending December 23, wind turbines produced on average 8.6 per cent of our electricity, but the moment the latest bad weather arrived with snow and freezing temperatures, this figure fell to as low as 1.8 per cent. The slack was immediately taken up by efficient, but dirty, coal-fired power stations and oil-fired plants. ‘What is so worrying is that these sort of figures are not a one off,’ said Mr Nicholson. ‘It was exactly the same last January and February when high pressure brought freezing cold temperatures, snow and no wind.’ In fact last year, the failure of wind power to produce electricity was even more profound.
