So all houses will be powered entirely by green offshore wind. What if we get a dead calm day and fog so no wind and little solar ? It's like the lets all get rid of gas boilers brigade, lets get everyone using gas for starters, I live in the south Wales valleys we have a percentage of properties here where that still use coal as the primary (and sometimes only ) heat source, and of course because coal is expensive they burn any old wood they can get their hands on. Electric cars great idea but you can only park one side of my street how do the other side charge cars up ( indeed how would I, at times I end up parking on waste ground 400 yards away ) I asked the guy installing my solar panels if he could install a charge point for electric car he said he couldn't as if it tried to run from mains I could pull so much power I'd melt the cables ! Labour want all properties to use solar, again great I have these, from a 4KW system on a good day I could put 20KW into the car, on Sunday my maximum output was 400 Watts ( and will be lower as we get into the winter ) External insulation of old stone solid walled properties, I've seen the nightmare in some, of the walls getting damp and the insulation making it worse.

Don't worry, according to the debate on Sky news this morning BJ may not be around for the long term (suggestion was that Gove would take over as a stand in PM and then Rishi would take over before the next election).

I suppose if total annual house heating requires x MW and offshore wind provides x or more MW then it has been achieved, even if it doesn't balance out each day.

<snip> Electric cars great idea but you can only park one side of my street how do the other side charge cars up ( indeed how would I, at times I end up parking on waste ground 400 yards away ) I asked the guy installing my solar panels if he could install a charge point for electric car he said he couldn't as if it tried to run from mains I could pull so much power I'd melt the cables !<snip> What exactly did you ask the solar installer for? Depending on your home power set up and if you are looking to connect directly or via an extension point then yes you can certainly melt cables. Ask me how I know! But if your home power set is sufficiently up to date, and the National Grid will come out to sort this free of charge in some cases, you just need a purpose-built electric vehicle charger (gov't grants cover about 40% typical cost). EO Mini Pro 2 has an add-on that will link to your solar panels and do a parallel/solo low-level grid pull in case you're interested.

I see the Daily Mail readers are back in force.
I have solar and externally insulated stone house. No damp, no power bills, nothing, nada, well a small income. ' In the same way as all the oil and gas plants in the UK require storage to spread the energy from one part of the day to another (and to get it from Saudi to the UK, and to hold it in tankers etc etc so will wind and solar. A fantastic opportunity to store more wind power is just, by storing it.
Energy is also stored in car batteries and will be plumbed in to release energy.
Come on guys the options is Climate Change. Choose your options
1) Well what about china?------have a look at how much China is investing in Hydrogen and Green Industry, lots
2) Well I don't believe in CC.---- so stop reading the Daily Telegraph 3) But that means I can't fly to cheap holidays as is my perfect right---- sure but 1) your are not paying your share, 2) look at Airbuses technology
Basically grow up, the world isn't as you just want it, it as it is.
I find Boris a lazy fool, but thankfully there is someone in the pot of dumbos who gets it.

I stopped flying for 10 years at the start of the century, I try to make things last and avoid buying unnecessary stuff. I have used only 100% renewable electricity and fully offset gas for many years, I have solar, electric car, and installing more solar and battery storage in two weeks time. I am fascinated by some of the advanced storage systems such as Highview LAES and simpler ones such as Gravitricity. I think that we could have done much more over the last few decades particularly in making new builds more energy efficient. However, I don't feel the need to preach to or berate my fellow human beings, dig up college lawns, or glue myself to railings and I don't mind perusing the Daily Mail from time to time.

The aim is to create a surplus of renewable energy on good days (Days other than those ever so frequent nationwide dead calm and foggy days the naysayers like to go on about). This surplus energy can then be used in a huge variety of economically productive ways when it is available. I'm not sure exactly how anyone can spin cheaper, cleaner electricity as a bad thing?
The 'powering x households' quotes you always get is just a reference point; like how area is in football fields, or weight in passenger jets/elephants.
Like bobo said, the alternative is more climate change. The world is just waking up to the economic cost of the ever more frequent storms, floods, wildfires, damage to health, etc it is causing.

I stick the e-Kangoo into a normal house socket via it's charging cord. Nothing melts. The plug socket doesn't even get more than slightly warm. Bobo's right, the electric cars can function as battery reserves to smooth peak demand. en.wikipedia.org/wiki/Vehicle-to-gridwww.ovoenergy.com/electric-cars/vehicle-to-grid-chargeraj, surplus energy would be ideal for producing hydrogen, which is first a storage medium and secondly has wider applications than current battery powered tech.

I have used only 100% renewable electricity ... for many years
Unless you only use electricity you've generated personally, and are off-grid, then... no, you don't. The "100% renewable tariff" lark is one of the biggest bits of greenwash of recent years. You get EXACTLY the same electricity as everybody else. It's just that there's some behind-the-scenes jiggery-pokery with generator funding. Except for the minor detail that if the green tariffs don't use all the renewables that are generated, they don't stop generating... They sell them to the grid anyway. These tariffs were probably a good incentive back in the day, when renewable generation was fringe lunacy... but those days have long gone, and the generation is mainstream and staying. www.gridwatch.templar.co.uk/ - National Grid power sourcing, live and historical. Renewables are right now producing somewhere around 25-30%+ of the UK's electrickery (depending on if you view Biomass as "renewable"*). There is no way that anything even remotely close to that proportion is sold via bunnyhug tariffs. * - the jury is, AIUI, out because of the amount of oil-intensive transportation involved in a large percentage of the fuel - as well as much of it being better used for more productive uses. Don't get me wrong - more renewable is most definitely a VERY good thing... But, yes, there's going to need to be backup generation or serious storage for becalmed days. And, frankly, I don't trust BJ Piffle to get this right any more than I trust him to get anything else right. If he promises 100% renewable, then I'm starting looking for where the new coal power stations are going... But I suspect this is no more than "Oh, look, a squirrel. La la la."I'm sceptical about vehicle-to-grid demand levelling. If I've had an electric car plugged in for a day, and I want to go now... I damn well want it to be fully charged. I do not want to have it say to me "Sorry, mate, but there was a bit of a local spike in demand, so if you wouldn't mind just stopping for a recharge at the services..."

From the outset, it was quite obvious that BJ was the best available tool to get rid of JC. Now this has been achieved and they don't want Boris anymore. I think Murdoch prefers TB/DC type of characters for the role.

The only thing saving his backside right now is that nobody else wants to get their hands dirty with it. Rishi? He'd do it least badly of any of the current mediocrities, but there's no escaping that he's ultimately the wrong shade for the party to get behind as leader/PM.

Yes, I'm sure Rishi won't be given that role. There is one that would do anything for the role and the "donorship" seems to be keen on his flexibility, but that will require a snap election, which in current circumstances is not an attractive options for those who invest their cash in politics.

I use a supplier that provides electricity backed by REGOs and I am satisfied that OFGEM provides efficient, effective, and transparent administration of the European REGO scheme. It is possible that I am mistaken, however, I have seen no evidence that the scheme does not operate as intended.

I do not want to have it say to me "Sorry, mate, but there was a bit of a local spike in demand, so if you wouldn't mind just stopping for a recharge at the services..."My understanding is that peak grid demand is around 16:00 to 19:00, EVs could help to support this demand and still easily be recharged for the next day by using electricity during the low demand window of 00:00 to 05:00, indeed an attractively priced tariff from Octopus does something very similar to this but currently only using battery storage rather than V2G EV batteries. Most EV owners charge their batteries to 100% only when they are going on a long trip, the usual routine is to top up each night to about 80% which is more than enough for the average day.

Who are you thinking of? An election would require all those "red wall" Tory turkeys to vote for Xmas, and (wivbreggzitduninnit) their primary attraction to the electorate is gone.
