Severn Barrage Payback Less Than Six Months

When I saw that headline in Building Talk, I had to force myself to not spin into a hysterical laughing fit; the UK's record at large scale civil engineering projects is not, well, exactly what you could define as top notch. But, reading the article, it does not mean payback in the usual ROI sense of things; what they are claiming is that the carbon costs incurred during construction will be paid for in just six months of operation.

Now that is an equally strong claim, and one that I find a little difficult to believe; but I'm no expert in these things, and if the barrage does eventually produce something like 5% of the UK's entire power requirements, then maybe they are correct.

We may have to wait more than a few years before the actual benefits, both in terms of ROI and in terms of carbon saved are realised, however, as the downside to the Severn Barrage concept is almost certainly going to be the environmental arguments that will inevitably hold the project up for another decade or so before construction even begins.

Tides of Opinion

I am aware on various issues regrading the controversial Severn Barrage tidal proposal; too much to hope our national news will help clarify matters sensibly.

I have written:

I have just watched the BBC Breakfast News 'report' on the Severn Barrage. Being already aware of the ecological objections I was keen to learn more objective information on the claim that it makes no economic sense, but this only amounted to a member of the RSPB saying so (if based on a 'report'). Hardly in depth. Or objective. 'Balance' was provided by an 'expert' who was quoted more on what the alternatives, specifically wind, would involve... to wildlife. What about the economic arguments we were promised? Or any hint as to this scheme's potential in reducing greenhouse emissions effectively?

I am also intrigued at the comment passed that governments should not be involved in huge energy projects. Er... do what?

Is the BBC just a mechanism to read out press releases, or can we ever hope to get news and analysis in forms these days that allow sensible understanding of the issues?

Having it all ways?

No, I am not trying to get banned.

It's just what popped into my head when the ever-excellent Ecologist quoted the usually excellent Friends of the Earth on the matter of the Severn barrage (I'll pop in a link if I can find one):

"To seriously damage and important wildlife site to generate less than 1% of the UK's energy is not the way to lead the world in sustainable development'.

Hmnn. I can see a literal point being made here, but surely it is outweighed by a host of practical ones.

The big issue is nature vs. man (as if we are not part of the ecosystem as an organism, and were designed by...?). Yes, this will trash yet more green and pleasant to provide a less than essential commodity to feed such must-haves as the PC upon which I write.

But I am darned if I can see what the FoE expect. Even without Global Warming polar bears would eventually be consumed by Club Nome, as our population expands without check.

I'm afraid that, on a a pragmatic basis at least, if there is going to be a demand for energy that is currently fulled by carbon, I fear 99 more wildlife reserve may have to be sacrificed to meet it.

Or... we could just cut back. Odds?

Barrages and other obstacles

For a long time I've been following in the local papers a discussion about a proposed Severn Barrage. Now it has hit the big time: Inventive compromise may be the answer to dilemma

Coincidentally the man vs. nature has already sparked a small piece already in another blog, this time from waaaay over in California.

There are a few potent causes fighting here. I am afraid that if 'we' are not prepared to do much/anything about our expanding population's (global and national, no inference on certain points made about on this topic recently ) calls on land and resources, the area will be toast (or a shopping centre) one day anyway. And this does not seem to be a trade-off deal. This is (very broadly) free energy as a substitute for carbon-emitting ones. I don't see the birdies winning.

BBC - New study for Severn energy plan - I have to say the Civ. Eng in me thinks this is waaaay cool. And I can see the enviROI shaping up well. But as to the birds... better this than Prescott's heirs sticking a condo on it?

Indy - Some worthwhile views

Indy - 'Strong case' for Severn barrage

Guardian - Barrage of turbines across the Severn could provide 5% of UK's electricity - Could? How can they not know? All the figures must be available.

Guardian Letters (ta, Dave) - very useful input!
