You have acknowledged that wind power needs energy storage. If not you should account for the cost of idle conventional plant in the cost of the wind energy.
Except I made extensive care to
not say that but you'll insist I did anyway to further your points. Wind power is economically viable without storage, if you want it reliable you need wild over provisioning across a wide geographic area which may be impossible for the UK. But without any of that simply as a unreliable generator its a profitable enterprise without the need for storage.
lookie here, its an entirely separate clause....
In a fluctuating electricity market such as the UK
or Australia has, storage systems are already able to profit and/or improve the security of supply.
entirely distinct and separate operations that do not require each other in the current market today or the predicted market into the future.
You have proposed that tidal barrages can be used to store energy. They can - but only for a short period, not the periods necessary for blocking high zones.
If you try to store energy for more than a few hours with a hypothetical Severn barrage (the best candidate in the UK), then you would have to raise water levels and create floods.
Except you jump straight to straw man arguments which we have previously addressed to try and make outlandish claims, while I never said tidal energy storage would carry over long periods. Its a storage system which happens to have a few hours of practical storage time, which could be part of a mix of storage systems. But you continue to make plainly ridiculous statements that it can't do this or that, or it will be a huge disaster when the opposite is true.
A tidal power system is a unique generator and storage capacity that is inextricably linked to the tides 745 minute cycle but it can deliver reliably scheduled power at any time during that cycle as the operator determines is appropriate. Tides have been able to be predicted for hundreds of years, electricity demand can be predicted with surprising accuracy, combine the two and you can predict when is the best time to deliver power and when it should be absorbed for pumping.
I refer you to your comments above, which show you know that is an overly rose-tinted viewpoint! You are trying to have your cake and eat it.
I'm willing to point out and discuss the real drawbacks such systems have but you seem unable to move from your entrenched position of straw man arguments and rubbishing any suggestion from others that renewable energy might be the only way the UK can achieve energy security and independence. You're welcome to point out other energy resources which the UK could use to power themselves into the future but relying on imports and world markets is what caused the blackouts you brought up as the horrible situation that must be avoided.
You evidently haven't read/understood "Without Hot Air". The second page of chapter 1 contains this important point describing a primary motivation for MacKay writing the book in the first place
Other than conversing with the Author and contributing to the work,
Interesting. What was your contribution?
The contribution today is pie, meeting your face, and the world is a slightly better place for it. Some of us actually contribute, learn, and share ideas, rather than trying to squash discussion and I'll make no assumptions about your lack of understanding on the topic so you should be polite and make no assumptions about others knowledge and experience.
