Our onshore wind power production is still more than offshore, which is catching up.
I read that one problem is that all developments are private. The developer gets the profits, so locals don't benefit.
The noise is a real problem, even if you can't hear it. Apparently sub-audible frequencies wake people up in alarm.
As a matter of interest GE's pic is this:
which doesn't account for sub-audible frequencies.
Onshore wind is still by far the cheapest to install and run of the green energies.
You can find stipulations for anything from 100m to 1km for distance from homes. They're also a risk to pipelines, it says in one article.
The distance betweeen is quoted as around 5 to 10 diameters.
Windswept moorland then, but people don't like the look of them.
Storage remains the elephant in the room. Sand batteries? Conversion to hydrogen?

Possibly me (although maybe I mentioned wave power). I covered this in Economic geography at school in the late 60s/early 70s and it stuck...
The figures bandied about for the Severn Estuary seem to be around the 720MW peak rating figure which in comparison to the La Rance station in Brittany, France (opened 1966, peak rating 240MW, average 96MW, annual 600GWh) and which is the second largest tidal power station in the world, is huge. In fact the proposed Swansea Bay project in the UK is the same peak rating as La Ranmce *(240MW). Maybe worth pointing out that the largest project in the world is the Sihwa Lake project in South Korea (2011, peak rating 254MW), so the Severn Estuary project is huge in comparison.
When you consider that the UK is estimated to have more than 10 gigawatts (GW) tidal power capacity, or about 50% of Europe's total tidal energy capacity, it seems to makes sense to at least investigate it. Build time for La Rance and Lake Sihwa was around 7 years - significantly less than completion time on a nuclear power station

Are you taking the p?Blimey all the tech that is being made available
Slash bags for example
Take a slash in said bag and you can charge yer phone with it
Way I see it this could be scaled up
To power yer house a sort of super slash bag
Perhaps advise should be taken from some attending the Glastonbury
Festival they normally have alternative energy displays and exhibits run by bombed out of there eads tree huggers with the latest pedal power leccy generation caper
Tis the new tech
Years ago they had telleys that you had to put money if you wanted to whatch it
Now there will be telleys with a funnel
Want to watch the telly you will have to take a slash in it
renewables make a lot less sense if you confine yourself to your local area.
for example, sometimes the wind blows in Cornwall, sometimes it doesn't
In the dUK as a whole, more often than not it is blowing in Perthshire, or Suffolk, or Cornwall, or Sussex, or Northumberland, or Gwynedd
People who are not Brexers will be aware that if it isn't blowing in UK, it is probably blowing in Finland, or Spain, or Sardinia, or Holland, or Algeria, or Ireland, or the Dogger Bank.
There;s a lot to be said for forming a co-operative group that includes others.

Of course, that's why we must send our gas to Germany and Hungary.
That’s a good idea as long as Josef from Slovakia doesn’t get automatic entry rights to the UK and access to our services without paying a penny in to the system just because we get a few volts of electricity from Belgium.
Luckily the EU, for example, does not have uncontrolled migration. There are rules that countries should enforce (unless they can't be arsed).
I bet you're glad you have to apply for a Visa when you go on your booze cruise to Calais.

Where do you think we send our surplus electricity, when we make more than GB can use?
Interconectors for electricity is a an obvious win for all parties. It reduces risk and allows electricity to be used instead of wasted in day to day use and allows both systems more resilience in the event something goes wrong.
Also, we do send our gas to the EU, and they send it here. It's a shared market.

We used to have Rough storage, which cost £75 million a year to keep safe, but the Tories closed it down.

I thought Centrica closed it down and the Tories are helping to finance the re-opening?

Obviously you misread. I didn't mention electricity. Obviously electricity goes both ways.
Gas does too though mostly we're buyers of course. It's not Britain's gas, it's privately owned and goes to the highest bidder.
'One reason for the exports is that the UK has very limited capacity to store gas compared with other European countries.
The Netherlands has nine times the storage, while Germany has 16 times.
This gas often flows back to the UK later when it is needed.
Britain produces about half the gas it uses domestically from fields under the North Sea and Irish Sea.'
I was referring to your comment:
"There;s a lot to be said for forming a co-operative group that includes others."
I suggested "Of course, that's why we must send our gas to Germany and Hungary.|"
If Putin gets really petulant, Germany runs out of gas.
So, does your enthusiasm for co-operation extend to sending them some of the gas which we would prefer to keep, so we can all share the pain?
