What i do trust is evidence, particularly an actual track record of delivering cheap and secure energy in sufficient quantities. Whilst there are issues with gas prices since the Ukraine war,
This is a bit like saying that whale oil had an actual track record of delivering cheap and secure energy for Victorian England, so we should continue using whale oil. Whilst there are issues with whales being hunted to extinction...mumble mumble carry on using whale oil.
Energy markets are always changing on a decade+ scale - the move from town gas to natural gas is perhaps the most recent example before the current one, as North Sea gas came onstream. These things take time, and money, but you end up with a better system - at least, as long as North Sea gas is flowing. But it's running out, we're now importing over half of our requirement, so it's time to look for a more secure replacement.
Ukraine is not the problem, it's more a symptom of how gas markets have changed. Previously gas was almost a waste product of oil extraction, and it was delivered point-to-point on long-term "take or pay" contracts - you had to pay for it whether there was demand for it or not. And if you wanted a level of protection against problems, you had to build underground storage.
But in the last 20 years a truly global market has developed thanks to the development of a spot market for LNG, and in our wisdom the UK decided that as we became more dependent on imports we would rely on the LNG market for emergencies rather than building underground gas storage locally. Which is fine until you have a crisis, as the spot LNG market responds to demand in a way that pipeline gas doesn't, and also all gas in the system is priced off the marginal therm.
So wholesale gas is currently about a quid per therm, but when we were exporting gas it was around 10p/therm (when you will have got your idea that gas "had a track record of cheap energy in sufficient quantities") but as we started importing increasing amounts it moved to about 40p/therm, and the first great crisis of the LNG era it went up to over 450p/therm.
- what i really dont understand about renewables is this (and I promise it is a sincere question). If they are so much cheaper then why is so much subsidy and incentivisation required to drive a transition ?
We're starting to get into questions that deserve a whole essay, but the short answer is that it's only quite recently that all that investment has started paying off so we're only just starting to see the benefits. So if you assumed 40p/therm gas as we had for much of the 2010s, that needs electricity at around £50-60/MWh to justify investment. Now look at the orange dots in the following graph, the auction prices for British renewables. You'll see that offshore wind hit £57.50 for the first time in allocation round 2 in 2017, but for instance one of those projects is Moray East which
produced first electricity to the grid in June 2021 and did not reach full capacity of 950MW until the end of 2021. Another was Hornsea 2, the largest offshore wind farm in the world at the time, which did not reach full production until August last year.
It's probably no coincidence that the highest subsidy under the current system (£10.97/MWh on line 14 of tab 7b) came just before Moray East came on stream, and the highest rebate (£16.82/MWh) came after Hornsea 2 came on stream. Hopefully the round 3 and 4 windfarms will boost rebates further, it just takes time to build them.
You're also seeing real-world windfarms choosing to opt out of the subsidy system altogether (and as a result have been making bumper profits under recent prices, as they don't have to pay back a rebate), SSE's first was built in 2021 :
https://www.sse.com/news-and-views/...-energy-opens-gordonbush-extension-wind-farm/the first wind farm development to be built by SSE Renewables on a merchant basis, which means no subsidies or CfD support were used to finance the project.
Another element you don't hear so much about is the huge sums the Treasury (via the Crown Estates) has been taking out of the industry in seabed rent and licence fees. For instance
BP are paying £462m per year for the Mona/Morgan area off North Wales, before a single turbine has gone in the water (and as an aside are talking about taking all 3GW outside the subsidy mechanism). So that's over £16/year per household that is going to the Treasury just for that one windfarm, that ultimately gets paid either by BP or the electricity consumer. Who do you think will win that battle?
Following on from that, is a question about the time horizon - i can see they may be cheaper since the utility bill spike caused by the Ukraine war - but would they be cheaper when gas prices return to historic levels ?
Gas prices are not returning to the 10p/therm of 20 years ago, and they're probably not coming back to the 40p/therm we saw through the 2010s - the globalisation of the gas market via LNG means there's now a single global gas market and the gas goes wherever the demand is highest. The commodities markets think that the UK will see prices around current levels or a bit higher, 80-110p/therm, for the next three years at least :

The recent reductions in the cost of renewables means that even without any carbon costs, gas-fired electricity would need gas to be down below 50p/therm at least to be competitive - and even then would need a hedging strategy that is unaffordably bulletproof to protect against a Ukraine-style spike. Given that they have to pay carbon costs in the real world, I'd guess they would need gas below 30p/therm maximum and I (and the futures markets!) just can't see that happening any time soon. Probably the only way to do it is via the capacity market which is what Eggborough are trying to do, but there's not too much confidence in the current iteration of the capacity market, it seems to have scared off Tees for one.
And why are utility retail prices taking so long to come down then - according to ofgem - wholesale prices have long since dropped? Clear and transparent answers to these questions will be vital to convince the wider public on this.
I have a feeling the an answer may lie in your reference to row 14 in tab 7b above (!) but i'd be really grateful if you can explain in laymans terms.
It's a really complicated area, that would need an essay or two to address in full. Some of the factors are as mentioned above, current gas prices are still double what they were pre-2020 and on the futures markets they look set to stay at that level for the foreseeable. Utility company balance sheets were generally a mess beforehand and were put under even more strain by having to buy gas at spot rates in the last 2 years. That meant a ton of them went bust and effectively consumers of the other companies are paying for them, whilst also seeing their (already considerable) interest bills on their debt cope base rates going from
0.1% to 5.25% since December 2021. And yes, there's a lot of capex associated with the energy transition - but the status quo of producing electricity from gas at £1/therm isn't financially sustainable either. You almost feel sorry for them. Not quite, but almost...
To go back on topic - there's an analogy here with the electric car debate after Sunak pushed back the deadline. The zealots argued absurdly that this would make life more expensive for consumers because electric cars are (or perhaps, will soon be) cheaper than ICE equivalents. If that is true then the govt deadline wont really matter as the transition will surely happen naturally, driven by market forces.
The main trouble is that something can be "cheap" and "unaffordable" at the same time, depending on the timescale, and this area tends to have a lot of "spend to save" decisions. So you might have a "project" (EV, solar panels etc) which might cost £6k and save you £2k/year over a 10 year lifespan. If we ignore finance costs for the time being, that looks dirt cheap - you make £14k profit over 10 years. But it's not much good if you don't have £6k to put up front. Now one answer might be for a company to come in and offer to pay the £6k for you, if you can split the savings 2:1 in their favour. That way you get £6,667 for free, they get £13,333 minus £6k = £7,333 less finance costs, everybody's happy. That's how capitalism works.
Except that's not really been working in the energy efficiency world. There's been some projects like that, but not nearly as many as there should have been, for various reasons. Partly because government has been unable to work out what it wants, because it's been distracted by Other Things and also just because things like insulation aren't very sexy. But that's the kind of social and market factor that I was referring to in my earlier post - but that's a whole other area, which again has been the subject of far more detailed analysis than you get on a homebrew forum!!!!
