How Lagoons Work
There are a number of them at various states of water levels. There will always be power generated. Think of one large dam wall in a circle in a shallow sea, split it into three sections. The centre section could be 30 foot below the outer two and the high tide level, and fill up via the other two or the high tide.
It is a matter of having the lagoons filling and emptying at different times to ensure full power production 24/7. A test lagoon is being suggested at Swansea in South Wales.
This is different to tidal only at La Rance, France. La Rance is just one power station. It only generates when the tide is running one-way. It is quite old now - 1966. Pioneering it is.
Political Spite Makes Matters Worse
Hard nosed cost/benefit eliminated the British coal industry (or more political spite by Thatcher hating miners). Middle Eastern oil was buttons to buy and the North Sea was full of cheap gas. Mrs Thatcher was told to reserve the gas for primarily domestic use and not use it to generate electricity - use the masses of coal we have under the country to only generate electricity. She never. The coal industry disappeared with amazing stocks still under our feet. The North Sea is running out of oil and gas.
Fuel Poverty is a major Problem
Domestic gas prices went through the roof because of world market conditions - the Uks gas is mainly imported. Fuel poverty is now a major problem.
Long Term Political View is Important
We are now are semi-dependent on Russian gas as we used a lot of our own reserves needlessly. Russia refused to supply gas to the Ukraine a few years ago, so alarm bells rang. We need stable fuel supplies. We get oil and gas from the politically unstable Middle East and Russia - which is a political concern over cost/benefit. They have to look at the long term and stability, not short term gains of utility companies. Then there is the important eco angle too. Tidal lagoons are both the long-term practical answer and politically acceptable.
25 Year Project
It will take 25 years. However benefits will come quicker than expected.
To meet 100% of Britain and Ireland's need for energy, this is clearly possible and mostly involves hauling rock from mountains and valleys to the sea on an unprecedented scale.
Fuel poverty and pollution will be a thing of the past.
Cheap Fast Transport
The EU has a transport dept that looks at transport for the EU 20, 30, 40 years hence. The aim is super fast intercity trains between all major cities/centres. One idea is a tunnel between Liverpool and Dublin. As Holyhead is the halfway point between the two cities that appears a dumb suggestion and a loooooong expensive tunnel. But a tunnel from Ireland to North Wales at the shortest point and then a fast link to Liverpool, Manchester, Birmingham, London is feasible.
However, damming in the Irish Sea to make lagoons to produce all the power for the UK and Ireland would create maybe two land links anyhow and maybe one to the Isle of Man. This gives high speed transport bridges. Super fast Maglev trains between major centres and to Ireland become feasible as running cost are low.
All cars can be electric, and the auto industry is currently moving that way.
Overall the lagoon project is well worth looking much deeper into, and clearly looks highly feasible when all points are viewed.
