ALAN Sangster (Letters, May 27) makes several excellent points on the subject of international co-operation to help combat the problem of intermittency when discussing renewable energy production.
In his listing of the various forms of renewables and in his analysis he fails to mention that the one source that has been singularly ignored by successive governments is tidal barrage or lagoon schemes. No country in the world is better suited to investing in such renewable technology.
It uses proven turbine technology, for it is nothing more than a hydro electric power station but set within tidal waters.
The station has in any one day four periods of generation and these periods are entirely predictable by the tide tables for the location. What's more there is a 12-hour difference between Cornwall and Caithness.
What is lacking is Government taking an overall strategic view of electricity generation in this country but sitting back and letting the generation companies go for the easy short-term solutions, none of which is going to provide us with a dependable sustainable and carbon friendly electricity supply for centuries to come.

Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
