THE SEVERN BARRAGE – IS THE TIDE TURNING?
A Severn Tidal Barrage could generate 8.6GW of renewable electrical energy and save up to 18Mt of CO2 per year. In addition, it would protect 140 miles of coast from flooding, it could provide road and rail crossings of the estuary, and it would stimulate investment in the region bringing employment and leisure benefits. Major studies of the project were carried out in the 1970's and 1980's and this paper concludes that a re-appraisal of the project should be carried out now.
