"Wind generates more than a quarter of UK electricity" (Wikkipedia).. free from raw energy costs, free from imports from Russia... where is the farce?

How long does it take to overcome the in bedded carbon from the actual turbine, thousands of tonnes of concrete and rebar plus all the other guff.

 

If it's sooooo free why isnt it cheap then ?.

The UN 🤔 an organisation renowned for its integrity nowadays. 

Is the word venerable, like those weird lodge types. Fancy handshakes, brown envelopes and such 😉

Not sure but over the life the concrete is less carbon intense than oil... though running out of time today to check the figures

 

 

Cheap... because of the way the pricing works... the rate they get is based on the price that the gas generators get (I think it is based on the gas generators). The excess from their costs is pure profit but nothing the generators can do about it they are contracted to receive that amount. Likewise they are contracted to turn off the windmills if there is too much power - given a free market they should be able to lower prices a lot and given decent energy storage be able to generate whenever the wind is blowing... hopefully someone with a remit for renewable energy this next government can sort that pricing out to lower our costs... but I think that depends on more battery storage being available to maximise wind turbine generation... I can see in 10 years that our electricity costs won't depend on the price of oil but be more stable.

Quick Google 2MW is 30,000 tonnes

No concrete to talk of in an offshore wind turbine you dip shit, primarily Chinese steel manufactured using coal 🤷‍♂️

What do you think lubricates the working parts ?? Fairy dust

Laughing at you SP and the drivel you post 

Rapist eh, oh how you loved old Joe and his fondling of kids.

I watched a very factual Youtube about how wind and solar can only(as yet) follow national grid frequency, since they generate DC which must be changed to A.C with invertors, which must match the frequency they provide to the grid. Except when the grid goes down, these invertor sources muct switch themselves OFF. Which is so really really useful when the dammned grid is needing more juice. Etc etc etc

They actually require diesel generators for that reason, grid goes down and no power to furl the turbines or lock the blades and it's runaway and goodbye turbine.

 

They use gearboxes to shift gears and run motors, some are hydraulic due to the torque.

 

Mechanical gearboxes would probably explode with the levels of torque from the blades spinning.

Fair enough. I dont know what trumps or harriss policies are but surely there must be plenty of people who agree with trumps policies but think WTF is he going on about, I mean the immigrants eating cats and dogs thing was hilarious.

 

Anyway, I see nasa want to investigate musk for chatting to Putin.

The North Sea is a national asset and must be treated as such. Our offshore energy sector has...

Id suggest some on here read this  and a selection of the comments from people who actually know what they are talking about in regards UK energy. Rather than just looking up how much concrete is in an onshore wind turbine base ( everyone is different depending on the prevailing ground conditions) and presuming that’s how they are all built.
