The greenies are the ones who wanted a load of f*ck usless windmills and PV systems installed, instead of looking towards innovative nuclear development.

Your PV is not going to work once the mains goes off.

I'm not suggesting riots, but I think once this all hits home to the electorate (most of who couldn't care less until it's *their* TV/lights/cooker that stops working), there might well be some hard reshuffling of what sort of people are voted in to form government.
No, but the wind will be reduced. There's a limit to how much power you can take out of the wind before you stop it completely and new wind with extra energy can't get to you. It has a name, but I forget it.

Especially when the locals come round and see the roof structure as a legitimate source of firewood.
Judgment day for solar PV parasites is coming, chuck another Green on the fire.
like those who can't even spell incompetent you mean?
Explain to me how solar PV will keep your lights on after dark?
just watch the tactics in yacht racing. the expression 'taking the wind out of his sails' wasn't invented for no reason..
There is a scientific paper somewhere about the power reduction on windmills placed too close together.
And its the reason why the accepted average power density of a windfarm is only 1-2W/sq.m.

You only use it if you have to. You have your own fuel source to hand. No-one can cut it off dopey.
Utter bollocks.
Are there actually any people with the appropriate skills?
And during a power cut. Don't the invertors shut down without mains to prevent backfeeding the grid? From both the safety of any line workers and to protect the invertor from trying to power the entire neighbourhood.
True but I can run my home with no electricity. The PV is to save on my electric bills and get my stolen money back.
You have six months to get yourself a wood/coal burning stove (before next Winter). Get one you can cook on too. Get yourself a pile of wood in.
Stop whinging. You have had fair warning. Get off your arse.
Quite right. But see previous post. Stand alone invertors are available.
I haven't seen a gasometer/gas holder with any significant stored gas for ages. Do they get used at all these days or just for "bare minimum" storage?

I thought they were designed more to keep the grid at a constant pressure ? They were busy dismantling them in the 90s - Both South Harrow and Southall went - they used to have massive letters painted on them, pointing to Northolt and Heathrow airports respectively.
To be honest, given the bomb-happy nature of every disgruntled citizen nowadays, I'm rather glad there isn't a huge store of flammable gas[1] in densely populated areas.
[1]I vaguely recall it would be unlikely to "explode" as we know it.On Friday 22 March 2013 12:13 Dave Liquorice wrote in uk.d-i-y:
Yes. They have to by design.

I thought most gas storage was done by pressurising the UK main "grid" gas lines (not the street supply obviously).
Yes.
Some of them. But standalone ones are available.
Linepack. They pump the grid up to 75Bar overnight, and let it "bleed out" during the day (gas tends to be cheaper after 6pm). Many years ago I worked on the program which took all the individual contracts (negotiated individually - there were nearly 100) with the gas companies and had lower and upper limits, plus cost bands, plus rig shutdown dates, and weighed the supply against the demand (produced by another program, feed with telex data from the Met Office) and generated a list of orders which minimised compressor usage (most grid compressors are RB211s that can use enough gas in a day to supply a small town).
But that's the national high pressure grid. Local pipes won't have anything near that pressure - presumably there's a regulator where the offtake plugs into the main grid.
The other method of storage was LNG - but apparently it took a week to liquify a days worth of gas (or something like that). However there was an LNG port on Canvey Island where imported gas (in those days from Algeria) could be bought into the grid. There may have been another near Liverpool ... BICBW. However I know the Canvey site got sold off.
