I have an investment in a windfarm
My model based on average wind speed etc predicts around 160kWh should be my average August production yesterday I hit 20 ( Theres only partial data for 1 hour and 1 hour missing too ) Maximum for a day is 30kWh, so we are looking at the sort of wind speed etc more normal for the winter period.
my prediction of 160kWh for the whole of August has been blown apart by an actual of 260kWh ( as at the 25th )

Wind and solar are the cheapest electricity, well for sure if ignore the need of backup for a dull still day. However over all I think it is still competitive and a dam sight cheaper than nuclear and oil. I am convinced that in the medium long term it will be the cleanest cheapest power the intermittency problem being resolved by storage, power transfer over long distance from places where the wind and sun are happening now. Plus of course time of day charging , it's coming, I hate it, that's why I have a clockwork meter.

The return Varies but for the first 3 months i get 3.2p per kWh ( Should go up to at least 4.3p from January ) My investment cost me £2273 I should get paid for 3900 kWh per year for 25 years, yes it's long term, and realistically it's a hedge. The first farm actually paid 27p per kWh last year and investors in that have had 50% of their money back in 2 years Running costs are taken out before my return. As at now my return for August is £8.40 for262 kWh

Thanks for the information sounds like for a few grand you could be pretty close to self sufficient with a wind turbine in the right location. The idea of being energy self sufficient has always appealed to me, although I guess you would need to have a way of storing it when it isnt windy. Maybe with a Solar/wind combination you could get close to achieving this - maybe with a gas generator for backup.

one issue is that anything above 120% of your usage is viewed by HMRC as a business to subject to tax. I use around 3000 kWh a year of which 1000 or so is self consumption from my solar panels Let's say I buy 2000 kWh at 15p £300 Plus £225 SC this year I should get 3900kWh of Kirk Hill at 3.2p £124 ( This cost me £2273 to buy) next year because we are paying for cost overrun this year and building up reserves we should get at least 4.3p ( £167.70) So £2273 pays 1/3 of my bill But for someone on SVT at 24p using the same 3000kWh 3000 * 25p £750 plus 225 SC £975 Ripple return £167 so around 20% IE it's much more beneficial to those with solar and battery than no tech.

Except that is complete and utter rubbish (garbage in the native parlance).
Herewith the current advisory from the same National Hurricane Center (sic).
In text, as I have problems with the technology:
BULLETIN Hurricane Milton Intermediate Advisory Number 13A NWS National Hurricane Center Miami FL AL142024 700 AM CDT Tue Oct 08 2024
...HURRICANE AND STORM SURGE WARNINGS ISSUED FOR PORTIONS OF THE EAST COAST OF FLORIDA... ...RESIDENTS IN FLORIDA ARE URGED TO USE TODAY TO PREPARE FOR MILTON'S ARRIVAL AND EVACUATE IF TOLD TO DO SO BY LOCAL OFFICIALS...
SUMMARY OF 700 AM CDT...1200 UTC...INFORMATION ---------------------------------------------- LOCATION...22.5N 88.8W ABOUT 100 MI...165 KM NE OF PROGRESO MEXICO ABOUT 545 MI...880 KM SW OF TAMPA FLORIDA MAXIMUM SUSTAINED WINDS...145 MPH...230 KM/H PRESENT MOVEMENT...ENE OR 75 DEGREES AT 12 MPH...19 KM/H MINIMUM CENTRAL PRESSURE...929 MB...27.43 INCHES
I have no doubt, whatsoever, that Mexico is currently experiencing an almighty storm and that Florida is next in line, but these idiots are inventing things to suit their own purposes.

mostlywrong interesting, and thank you. I make no claims to being a meteorologist, sailor, or anything such like, so thanks for calling that out.

As a fully paid up geek, I keep an eye on that website. A lot of our weather comes from that direction and it is fascinating, and time consuming, to watch it unfold.
My guess is that Milton will burn itself out somewhere near Bermuda and the wreckage will be drawn into the airmass that will be over us in 7-10 day's time.
In the meantime, the Hurricane Center (sic) has published another advisory:
BULLETIN Hurricane Milton Intermediate Advisory Number 14A NWS National Hurricane Center Miami FL AL142024 100 PM CDT Tue Oct 08 2024
...AIR FORCE RESERVE HURRICANE HUNTERS FIND THAT MILTON'S INTENSITY HAS REBOUNDED... ...TODAY IS THE LAST FULL DAY FOR FLORIDA RESIDENTS TO GET THEIR FAMILIES AND HOMES READY AND EVACUATE IF TOLD TO DO SO...
SUMMARY OF 100 PM CDT...1800 UTC...INFORMATION ---------------------------------------------- LOCATION...22.5N 88.2W ABOUT 125 MI...205 KM NE OF PROGRESO MEXICO ABOUT 520 MI...840 KM SW OF TAMPA FLORIDA MAXIMUM SUSTAINED WINDS...155 MPH...250 KM/H PRESENT MOVEMENT...ENE OR 65 DEGREES AT 8 MPH...13 KM/H MINIMUM CENTRAL PRESSURE...923 MB...27.26 INCHES
and:
Aircraft reconnaissance data and satellite images indicate that maximum sustained winds have increased to near 155 mph (250 km/h) with higher gusts. Milton is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. While fluctuations in intensity are expected, Milton is forecast to remain an extremely dangerous hurricane through landfall in Florida.
Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 105 miles (165 km).
The minimum central pressure based on dropsonde data is 923 mb (27.26 inches).
I would not like to be anywhere near that, at sea or on land.

Flightradar24 currently shows a big hole over the Gulf of Mexico around which all the airlines are routing.
Except for a NOAA registered Gulfstream IV trundling around the Category 5 hurricane at 44,000 ft AMSL.
Balls of steel...
NOAA is the American oceanographic organisation.

Living within a mile of Portland bill stuck out in the English Channel with no shelter from the prevailing sw winds I kind of know what happens in a big blow. I think the worst we have had is gusts to 115 mph and I am sure that wind pressure increases by the square of the wind speed. Sustained wind speeds of 155mph mean gust of 200mph , wow, that will rip some buildings to pieces would expect cars to be pushed around and any high sided van would be over. Hope we do not get the tail end of this one in a few days, may go and put a few extra mooring ropes on the boat got a long length of 3 inch dia nylon should hold it.

The energy in the wind is proportional to the cube of the wind speed so lets say a wind turbine can extract 1.25 kWh at 5 mph at 10 mph it should be able to extract 10 kWh. and of course in the winter higher air pressure also adds more energy to the wind
