Don't dismiss barrage schemes

Letters

The cover story (NCE last week) is a timely reminder of the state of the UK's energy industry and the challenges we face. Half of Europe's tidal resource is located around the UK; a barrage across the Severn estuary with the second largest tidal range in the world (first considered in 1910) could supply 7% of UK electricity requirements.

Tidal estuary barrages have the potential to meet around 20% of UK electricity requirements.

Can we afford to continue to decline the opportunity to develop durable barrage schemes based on proven technology? They offer reliable renewable energy independent of weather, with flood protection and supplementary road/rail links as side benefits.
