Re: Tidal?
Why would you take tidal energy from Scotland down to Birmingham? That seems wasteful to start with. There are massive sections of coast far closer to Birmingham than Scotland and it's likely some of those would be more likely but generally Tidal energy would like be used for the closest areas first meaning the coastal towns first and then further inland with excess. However this energy reduces the total amount of energy needed in the UK completely. Somewhere like Birmingham which is nearing the point furthest away from any coast possible, would likely be on a different type of energy source but you don't need to use that same type of source for coastal areas powered by tidal power.
