Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

My understanding of the Severn barrier project is that it is a useless white elephant project that's used as a "green"diversion to get nuclear plants under way.

Wind, both onshore and offshore, works, has a understandable price structure (with a cap on said price, increasingly a luxury these days) and no physical limitation.

Indeed.

The latest proposed version seems to be a 8.6 GW plant, which is supposed to meet 5% of the UK's needs (that would be roughly 20 TWh/year, or a capacity factor of around 25%). A single giant project, 1500 times bigger than the largest wind turbine; but it is not much overall - and not much even with all the other potential estuaries barraged.

The same amount of electricity would be produced by off-shore wind farms with a combined capacity of 5.7 GW, assuming a capacity factor of 40%. The cost to build that with all strings attached, even at today's increased prices is presently around £17 billion I believe (but Jérôme correct me).
