The great thing about the UK is that's it's all publicly available.

https://www.gov.uk/government/publicati ... -framework

CfD strike price of £85.05/MWh for solar, £89.23 for onshore wind, £101.78 for offshore wind and £245.38 for floating. Market reference price of electricity about £63MWh this year, and historic norm is about £45/MWh.

Existing CfD contracts;

https://dp.lowcarboncontracts.uk/datase ... -emissions

£160/MWh for offshore wind, £111 for onshore wind, and £100 for solar — running costs about £200 million a month. Current CfD is only about 17% of RE, the RO scheme https://www.ref.org.uk/generators/group ... p?group=yr
is 60% of RE via a £31/MWh charge on electricity supplied to consumer. In the 2023/24 financial year, these subsidies cost consumers approx £7bn – resulting in a subsidy top-up of around £110/MWh, on top of the market rate, for each renewable generator lucky enough to have signed up to the scheme before applications closed in 2017.

This year, the scheme is set to cost £7.9bn.

This doesn't even count FIT which is probably about 300% over market rate, someone looks it up, nor balancing mechanism or capacity market which are network side costs.

All im pointing out are the figures. It's expensive.

If it could cry, im sure id be awash with tears.

Didnt Joeboy say leccy in Turkey was 3p a unit the other day?

Me thinks we get well and truly stiffed by the 'market'.
That 3p per kWh is set by the govt. I don't know the mechanism for the advisory roles played in this. Certainly to ourselves it seems very cheap but the Turks see the percentage when there is an increase and bemoan it. That is coupled with huge inflation and largely static wages over the last five years or so.

Bread is now 10tl(23p) per loaf, again this is a set price by govt but it's not that long ago that the price was 2.5tl per loaf. Bear in mind what I said about static wages...

For power itself I'm very much for reduce use via better home appliances and tech in both homes. Insulate and gapseal as much as possible, then generate all we can within the home space for power and heat in a responsible fashion (thinking seasoned wood on wbs).

No silver bullet that I can see but we do what we can.

My current fave and likely closest to a silver bullet is the A2AHP. A 75% drop in power bought to heat the space, with air con and moisture control as an extra bonus.

No probs mate, just me being silly as usual, especially when it comes to visits from bridge dwellers. According to a certain individual on this thread, there is a silver bullet, and it involves ice cubes, yes ice, ice baby!

I thought we were already getting gert big ice cubes dropping naturally into the oceans at an increasing frequency and size.

That concepts not going to end well though :facepalm:

I too noticed it's a bit dark, I've just been out with my torch to the rear garden with my tape measure. SWMBO, said "where are you going with that tape measure, its nearly midnight". :fight:

Been on the city plumbing website again and I'm plotting how I can take up the headroom left on my Victron DC charge controllers. :mrgreen:
