The issue with offshore wind is that it isn't always windy. If you look at modelling with energy system with a high proportion of offshore wind, you need other sources of energy which often isn't factored into the economic return of the original investment.
We are doing this because, for some reason, we have decided there is political capital in paying out these huge subsidies to large companies to produce expensive energy. I would think that would be obvious when the UK has extremely high electricity prices and renewable production is very high...where do you think the money is going? It is going to subsidise inefficient and expensive supply.
Also, one of the primary issues with the UK is that the political system heavily incentivizes people to blame "the other side" for these issues. The Tories were extremely aggressive in moving towards green energy but people who vote for Labour, because they support green energy, will have to believe the opposite. There are other posts on this chain that also blame the Tories for things that didn't happen. In this system, it is very hard for anything good to happen and is how you end up with someone like Starmer who appears to have almost no opinions on anything other than staying in power and keeping the gravy train going for the lads. Not serious. Expect things to get significantly worse.
Our electricity prices are much higher than anywhere else. I remember reading research last year that the cost of government intervention in so high that if gas prices tapered to zero, electricity prices would not fall. It is going to get much, much, much worse.
The reason why Hinkley Point is expensive is completely solvable. The reason why it is expensive is because it is supposed to be expensive, that is the purpose. An A road near me has required two lanes, so far they have spent near £100m over twenty years and have not built anything. The basic premise of the UK political system is that people have no idea what the price of anything should be because it is all a political fiction.
When the costing was done for Hinkley 10 years ago the price was going to be, iirc, something like 50% above the price of gas which was at record lows. This was regarded as extremely expensive...electricity prices are up multiples and multiples since then. Since then, you have had armies of lawyers, consultants, lobbyists, planners working on the project full-time...and you are asking why it is expensive? Thinking this requires knowing so little about how much nuclear costs around the world and having literally zero idea about infra projects work in the UK (spoiler: there is massive corruption at almost every level, tens of billions in graft every year).
Any savings they make constructing or overruns don't affect that.
So if anyone is grifting they are grifting the French taxpayer via EDF.

And yes, as I explain above but which you seem to have not read...there was unbelievable levels of graft involved with Hinkley. EDF is not the victim, the reason why the CFD is there is to pay suppliers to EDF which are: lawyers, consultants, planners, etc. At some point, someone may get paid for building a nuclear power plant but that is a largely accidental outcome. If you compare to what other countries with functioning political systems, Korea for example, it is multiples. The costs and prices are so ludicrous, so out of control that no-one could think they make economic sense...and, of course, they don't. It is just corruption.
Also, for years CfD rates were actually lower than wholesale price and are currently generating at lower strike prices than average wholesale prices. The problem now is more inflation, capital costs, and commodity prices for materials. But then a lot of other things are more expensive also.
Tories do not back the free market. You said it yourself, the two parties are the same. Elections are irrelevant, both political parties pander towards orthogonal groups of voters, they tell them they are different, and they get in government and will do the same thing. Reform will do the same thing.
Also, the characterisation of what the government is able to do is extremely inconsistent. Able to lock down the whole country by fiat? Happened in an afternoon. Able to approve a 2-bed house twenty miles away from anyone? Sorry mate, need 26 forms, planning authority, need solar panels, need heat pump, etc. One of the big issues the UK has is with the understanding of government, it is the most bizarre mix of extreme libertarianism and extreme authoritarianism. It is a country where police will arrest someone from criticising a politician or the police AND a country where the police are unable to investigate almost all crimes (fraud investigations are outsourced to banks and private companies but there is action at multiple layers of government to control what happens on Twitter).
Storage is not possible. Everyone knows this. What game is being played here? Which other medium-sized country has large amounts of renewables with as much storage as we require. Electricity prices are already ruinously expensive. The solution is simple: do the stuff that works, that is it. The UK is a tale in being unable to do simple things that work.
Interestingly, the reality is that the "free market" is making this happen and its already here. 'The UK grid-scale battery storage market grew 45% by operational capacity in 2025, with 4GWh coming online during the year, bringing total operational capacity to 12.9GWh.'

Again, this is the issue. People suggesting that stuff that makes no obviously no sense for political or social reasons. Why? This is a very simple problem too, but there is massive political pressure to find solutions which produce more corruption.
This is currently called natural gas. You store it in the ground, and in "day tanks" on land connected to pipes.
Nuclear can also be seen in the same way in relation to renewables.
Batteries are currently much further than I ever thought possible, but still nowhere close to being cost effective enough for most areas.
If you forced every solar or wind installation to have at least 48 hours of nameplate capacity in storage, you would get closer to the true cost of deploying renewables. Right now there is a whole lot of cherry picking going on, where investors are taking the profitable easy stuff, collecting subsidies, and then making the hard expensive stuff someone else's problem.
Right now battery deployments cover the few hour duck curve at best, because that's the only profitable way to deploy them. Hopefully the trend continues though!
I'm wondering if really, the causality is reversed: it's not that the renewables make energy expensive in the UK, it's that energy is expensive in the UK, which incentivized construction of a lot of renewables, because they're an overall cheaper source of energy long-term since you don't have to either pay your neighbors to import them or build rigs in the saltwater ocean?
There is are also two relatively big offshore fields that were taken to a very late stage of development and then stopped because of opposition by local government.
I would research exactly how big the gap is with other countries (and, remember, retail price is subsidised). The Cameron government made the active decision to order companies to shut down power plants with no plans for replacement. To be clear, nothing about energy...this is jut electricity provision. There was no economic incentive, that is why tens of billions were given to energy companies to produce non-economic, expensive power with guaranteed payments.
There was some research done last year iirc: if the UK paid zero for gas, the price of electricity would not stop rising because of the government intervention.
It is reasonable that you assume something rational must be going on here. But that model does not apply in the UK. Politics took over from economics a long time ago.
The Tories granted a hundred plus drilling licenses and so far they’ve yielded a months worth of gas supply
The price of petrol at the pump is at least 50% Government direct tax - fuel duty, VAT (which multiplies the duty value - very cheeky). Then the other parts - wholesale price, retailer profit, delivery costs, have their tax implicitly priced into that. That probably makes the overall Government take something like 70% of the price you pay.
As for coal, there's apparently about 600 million tons of accessible usable coal left, which at current UK usage is good for quite a few decades if not more.
This would have been a factory to produce wind turbines, which would have benefited the country. And I thought net-zero was a priority.
Essentially all solar panels are made in China. All our car factories are foreign-owned, and even nuclear power plants are.
And all those things you mentioned. I'd rather they were all home-grown but I can live with the French having a chunk of our Nuclear - because I like the French.
