The study you have linked is completely wrong.

There is no international market for gas because export/import is physically complex. This is why gas is priced very differently despite it being chemically similar (unlike oil). Anyone who says anything different should be immediately disregarded as someone who should not have an opinion.

This is technically true for oil but there are two other factors. One, importing oil is environmentally-intensive and relies upon the assumption of free and open trade in oil...hopefully, the last few weeks have demonstrated why this is untrue. Two, the assumption is that mix of imports is not changing, because of high energy costs and reduction in North Sea production, UK refineries are shutting down so we are completely losing domestic capacity across the whole space. Lower jobs, lower tax revenues, more reliance on imports.

The above take would be somewhat funny if we weren't ten years into seeing the consequences of this. At this point, we could be back to the stone age and you would have the same people screeching that inventing fire is dangerous.

Also, Roughs storage facility is in the sea...so I am not sure what "real estate" development was done here (the UK has been building 10-20% of the required growth in housing stock for something like two decades...again, the same people will be screeching about developers if we lived in caves). The reason it was closed was due to economics.

For some reason, you deny that producing more gas would be useful but are outraged at a storage facility closing when the primary function of a storage facility is to allow energy producers to arb derivatives markets effectively. I have no idea how this makes sense to you based on all of the above...perhaps you just want to complain about the Tories? I have no idea.

The current tax rate on North Sea production is 75%, there was ample opportunity for public benefit but multiple governments took that money and spent it on benefits. The reason why Norway has worked is because they incentivized exploration (again, something that you imply later would have no benefit...but okay). The policy of the last fifteen years has been to tax the industry heavily and disincentivize exploration. Revisiting this approach is extremely unpopular amongst all politicians which is why production has dropped. Even with this limitation, we have large gas fields that have been blocked (by the Tories btw) for environmental reasons.

This isn't complicated: if you want more oil and gas, produce it and create more incentives to produce it. The reality is that people want to have their cake and eat it: North Sea production is both very pointless but paying huge amounts of carbon to import from the Middle East is a good idea and we have to pay subsidies of 30-40% electricity bills to subsidies green production...which is also very profitable but requires subsidies because of Tory developers or something.

The UK isn't a serious country. What is happening to the UK is a reflection of phenomenally poor political leadership. It is deserved.
