Well I think a part of this is caused by us refusing to grasp the nettle earlier and spend the time and money required to get these other forms of energy generation to a point where they are viable. Now we're all going to be hit in the pocket massively because of it.
I agree we have serious short term challenges in changing this but it's made geopolitical sense to make this shift anyway, given how the main exporter of gas in europe is now well up for starting ww3. It's a difficult question with no easy answers but I think would be fair to say simply continuing as we are is emphatically not the best course of action.

Maybe we better start drilling again

And with tidal It's also really expensive at this moment and while they say it can supply 20% of our energy needs how many of them do we need at this high cost to get that figure especially as the techs still pretty new so will be inefficient? I know the proposals in the Severn saw something like 5 proposals with the cheapest costs £2.3bn. It's like with wind where the current turbines would take the whole of the Isle of Wight to be covered in them to produce the same electricty as a single coal power plant (assuming they could run 24/7 which they can't) and that many turbines would cost way more than a coal powered plant.Stop hovering to collapse...

It depends on the size of the wind turbines. There's just been a couple of huge ones built in Europe that are capable of 14-15MWatts so if you had 130-150 you'd get the same capacity as Ratcliffe power station which will be the only coal fired power station in England by the end of this year. Also, rather counterintuitively to my mind, the larger the wind turbine, the less wind you need to create energy.
Personally, I do wonder if giant "centralised" energy production is an outdated concept, whether it's from a traditional power station or from large wind/solar farms. Domestic energy production and storage is getting much cheaper so I can see a shift to a more decentralised system of lots of homes producing their own (probably solar) power and storing it in a domestic battery for personal use with the excess being sold back to the national grid. Obviously we're a long way off that at the moment and not every home would be able to be self sufficient but I think that this type of energy production will provide a decent percentage of the UK's production capacity in the next 20-30 years. -

@StaffordBantam how are you weighing up the pros and cons of switching to a heat pump and how ready is your house for it in terms of underfloor heating and insulation etc?
I know that current fuel prices might end up being a paradigm shift when it comes to switching to heat pumps but they are still relatively expensive to install and the cost is likely to come down dramatically (especially with the planned phasing out of gas boilers that's just over the horizon) so do you think potential savings on gas will cover potentially "overpaying" for being an early adopter of the technology before it becomes more mainstream?
Obviously I know that there are good ethical reasons for the switch beyond just £'s! -

They have installed a ground source heat plan in a local block of flats at an enormous cost drilling down hundreds of feet and most are unhappy with it as the heat produced has to be bolstered with an electric heat source to bring it up to a usable temperature. Most are now using oil filled portable radiators as cheaper to run

Often larger 'radiators' are required and use of a heat pump central heating system needs to be operated on an 'anticipatory' basis. It lends itself to smart technology very well.
Over the 2021/22 winter I've been trialling using my gas boiler at much lower temperatures than previously, to try and identify where radiator upgrades may be required if/when I switch to a heat pump system.
It sounds like the system in your local block of flats has not been installed correctly and/or the residents don't understand how to fully use the system. A modern heat pump system should be operating at efficiency of 400% plus, so if people are finding oil filled portable radiators (which are typically just over 99% efficient) cheaper, then something has gone badly wrong.Stop hovering to collapse...

In respect of the size of the radiators, we have ours mainly located under windows. We would struggle to fit in larger ones if they were substantially bigger. Finally I had been told that you virtually had to have insulation to such a high level, that most houses build before WW2 would not meet the requirement. If air doesn’t circulate, then the potential for mould and indeed dust build up allergy enhancing conditions could become more prevalent. I am interested on both an environmental/moral basis as well as cost.
