Hi ,
It looks like you're using an ad blocker.



The revenue generated from the adverts on the site is a critical part of our funding - and it's because of these ads that I can offer the site for free. But using the site for free AND blocking the ads doesn't feel like a great thing to do, which is why this box is so large and inconvenient. Some sites will completely block your access, but I'm not doing that - I'm appealing to your good nature instead. Did you know that you can allow ads for specific sites, whilst still blocking them on others?

Thanks,
Ian Williams aka Fetch
or for an ad-free Fetcheveryone experience!

I had a poor experience with Octopus about 5 years ago by email which sounds like Chrisull's experience by phone - they simply weren't reading what I'd told them (I got others to check what I was writing by the end to make sure I was being clear as in theory it was simple!). Eventually they got it correct (it wasn't that they disagreed once they finally understood).

Ok - it's up it's and live. They wanted a photo of my export amount, which I have done.

So configurers (in particular @HappyG(rrr) ), what do I now need to be doing/setting up to get maximum bang for my exporting buck please?

It's a GivEnergy battery and it's on a "Out going, smart export guarantee tariff" with Octopus.

OK, you need to change your outgoing tariff to whichever suits you best - I'm on Flux export. 4-7pm is 27p, and same for import, I'm on flux import 2-5am 15p. Then charge battery during cheap rate and discharge during peak rate.

Tada. :-) G

And I don't know if that is the best way, but given the difference between 15 and 27p is better than at any other times, it seems like it should be.

Just went over last year's bills, and very roughly, ignoring £30 direct debit and roughly £25 standing charge, the actual usage is roughly £250-300 credit in summer, and £250-300 charged in winter, so it's probably net zero overall. But down from the £2,000 a year that it would have been for electricity. And that includes home charging an electric car (on cheap rate).

So roughly a 6 year payback on a £12K investment? Not accurately calculated though. :-) G

And for enviro thread - net giving to the grid during 16.00 - 19.00 which is peak demand which drives use of gas turbine and other on demand generation, net contributing to the grid during daylight hours generally (though not getting paid much for it!) and generally offsetting our electricity usage to off peak 02.00 - 05.00 for charging battery and car, when base load is lowest and almost entirely non-fossil fuel generated.

It's not perfect, but if every house was fitted with a battery (never mind solar), it would help to balance the grid much better. :-) G

You can buy *way* more solar and wind plus storage capacity for £14Bn pounds and it can be online quicker, than you get with a nuclear power station. Why are Labour/UK going with nuclear? I thought Ed Miliband understood this stuff?

It was already signed off, from the previous govt. They've even cleared the site. Not sure any point in cancelling it now?

Sunk cost fallacy Chris. It's literally the first one in the "how to debate well" diagram in your other thread?! ;-)

No. It was bad to sign it off. The only thing worse than cancelling it, is not cancelling it and wasting more money. :-) G

I've not studied how the grid is made up in any great detail, in fact barely at all.

If we are to switch off coal/gas generators at some point in the future, don't we need something else, like nuclear, to fill in the gaps when the renewables don't work, eg at night when there's no wind ?? Or is there already something else to fill this gap if there's no coal/gas ?

Apols if that's a newbie question :-)

About This Thread

Maintained by HappyG(rrr)
Hi
I've seen environment (whether emissions, power, climate change, access to countryside, whatever you think of as "environment") discussed in various threads: Politics (obviously), the Electric Car thread fetcheveryone.com/forum/electric-car-anyone-61481/ , run free's excellent "Competitive Running and Keeping The Environment Clean" fetcheveryone.com/forum/running-competitively-keeping-our-environment-clean-60907/ my own Greta Thunberg thread fetcheveryone.com/forum/greta-thunberg---jfk-for-the-climate-generation-61044/ etc. but I haven't seen a general one.

So here it is. For those interested in the science, the politics, the action for (and I'll state that for me, this is mostly pro-environment, anti-emissions, anti-pollution etc.) and the hope for the future of our planet.
