With all this land erosion down the East coast, could lagoons not be created off shore and the tidal rushes into and out of the lagoons harnessed to produce electricity?

I've suggested some time ago allying coastal erosion protection with wave energy generators to make both more efficient and affordable.

both wave and tidal power are possibilities.
A large lagoon could certainly be built, and power generated as water runs in and out of the lagoon via turbines.
Might not be economic though, remember that we already have a natural formation suitable for tidal power, namely the Bristol Channel, but the idea of tidal power there has been abandoned owing to costs and the NIMBY factor.

Protection against coasal errosion normally requires building large concrete structures, and these could indeed by fitted with wave power generators, IF a fair way out at sea, would not work on a normal sea wall as this is above the water level almost all the time.

And of course any large concrete structure could have wind turbines mounted on it. A wind turbine tower could serve also as a lighthouse.

...and solar panels on the structure.

And just think of all the sports and leisure industry possibilities!
