The end of gas boilers....

and also consider that today ( very strong winds ) many if not all wind turbines are at a standstill Blades feathered with brakes on to prevent the unit over revving and destroying gear box and / or generator,

Surely not, https://gridwatch.co.uk/Wind

Nonsense

They were making 11GW last night and they're making 10.28GW now.

Gas is making 9.3

Nukes are making 5.8

 

[JohnD]

Happy to, where do you get your info and I can take a look?

I still want to see that thousand-year calculation.

Always interested to learn.

50-55 mph

Most of what you would call large-scale wind turbines typically start turning in winds of seven to nine miles per hour. Their top speeds are around 50-55 mph, which is their upper safety limit. Large-scale wind turbines normally have a braking system that kicks in around 55 mph to prevent damage to the blades.

yet the winds are stronger now than they were last night 11GW last night

 

[JohnD]

Yes, they are. And you still think that "many if not all" of them are stopped?

Rubbish.


BTW your website is severely out of date.

 

[denso13]

yet the winds are stronger now than they were last night 11GW last night

Wow, 10GW and most, if not all, are at a standstill! Even more efficient than I thought!

 

[JohnD]

10.95GW now. About the same as last night.

 

[JohnD]

Bernard has certainly convinced me that severe storms affecting most of GB are not the threat that he thought.

From Wikipedia
Wind power in the United Kingdom

Wind power delivers a growing percentage of the electricity of the United Kingdom and by the end of December 2019, it consisted of 10,267 wind turbines with a total installed capacity of over 22 gigawatts: 13,532 megawatts of onshore capacity and 8,483 megawatts of offshore capacity.

They were making 11GW last night and they're making 10.28GW now.

Installed capacity more than 22GW yet on a very windy day they only produced 11GW, which suggests that about 50% of the installed turbines were not operating. Or is there another explanation ?

 

[denso13]

Or is there another explanation ?

No idea. The average daily output over the past year was just over 5GW. There is obviously a lot more going on than just wind speed.

You still haven't explained how power was generated from wind today with most if not all turbines at a standstill.

Onshore Turbines
8,412 Onshore Operational Projects 2,395 Onshore Operational Capacity (MW) 13,575.315
Offshore Turbines
2,016 Offshore Operational Projects 37 Offshore Operational Capacity (MW) 8,483.420

Operational Capacity (MW) 22,058.735 22GW

Energy Produced (MWh/p.a.) 59,516,232 59 GWh

~~~~~~~~

In a year there are 8760 hours

If all that 22 GW capacity was operating continuously then 529,416 ( 8760 x 22 ) GWh would be produced in a year.

But the actual Energy Produced per annum is given as being 59,GWh

If my calculations are correct then only 11.24% of capacity was produced.

I do realised that no matter how many turbines there are installed without wind they are not going to produce any energy.

 

[bernardgreen]

if not all turbines at a standstill.

Perhaps "if not all" was a bit too far

 

[JohnD]

Windpower is not expected to be running at peak in every location at all times.

At any time there will be places that are windy; places that are not windy, and places that are too windy.

This is no surprise to anybody.
