Oui, pourquoi ce réflexe de passer à la trappe les solutions d'envergure ?Film preview of A Crude Awakening
Yesterday my mate Jeremy Smith (former editor of the Ecologist - so, a guy who knows his megawatts from his terrawatts) phoned on spec to see whether I'd be interested in joining him for a preview screening of a Peak Oil film and Q&A with the directors afterwards. Excellent, I said, I'm on my way. The film, A Crude Awakening, is to be released nationally on the 9th Nov. (...)
(..) But - it's a big but - the film then moves onto possible solutions, and wham! it seems to literally run out of energy. A slow trot through the (valid) problems with hydrogen, biomass, nuclear. Weirdly no mention of coal, and a petering out with a passing reference to solar. All a rather bleak picture which left most of the audience depressed and feeling rather hopeless. So this was strange - a film made by a journalist who had clearly done his homework (after all that's what you do, isn't it, when you go off and make a film?) - to a certain extent, then stopped short of examining what possible solutions there out there. Well, if you have been following my blog, you know that one of my passions is Concentrating Solar Power, which to me seems to provide a huge solution. This wasn't touched on at all and I wanted to know why.
Before I even did so, it came up, and to my surprise a stock answer was given that I have often heard given before - one that often comes from oil men and nuclear supporters: that solar is the key, it's just too expensive and will take forty years of research and development. [Commentaire : c'est exactement la position de Tiennel] This is strange, simply because it is not correct.
Firstly, I pointed out, the technology is out there. It is mature, tried and tested technology that has been around for 30 years. Commercial-scale plants have been operating in California since the mid 1980s and are still supplying electricity to about 100,000 homes. (In fact, versions of CSP have been tried since the late 19th century, not counting Achimedes' attempts to set the Roman navy ablaze). There are also sites here in Europe (in Spain) and plants are due to be rolled out in various sunbelt countries. Electricity can be transmitted economically for three thousand kilometres or more via a Supergrid of HVDC of lines (on pylons or laid underground or under the sea). With this technology, transmission losses are no more than about 3% per 1000 km. Cost wise it is already looking to be cost-effective against the soaring oil prices (which as I write have now hit $96 per barrel - they say it will reach $100 by end of next year, but it looks set to be far sooner than that). It has been estimated that only 113 km x 113 km of desert covered in mirrors would supply all the electricity needs for the whole of Europe - that is, in desert terms, a tiny fraction of available space (and available sun). You can find out more at concentratingsolarpower.infoand on the TREC-UK website.
"Well, hey what do I know, I'm just a journalist" was the response I got.(...) Well, if they aren't prepared to do something about it I am. I leave for Seville today and the reason I am going there is to attend a conference on CSP. I want to know just how viable CSP is, just how big it can go and how soon. We need big solutions as well as small, and CSP could be just that. Watch this space - I will be reporting back live from the conference. (...)

Cela serait-il fun et excitant d'imaginer l'effondrement de notre société, la fin du monde, l'apocalypse ? Cela serait-il au contraire déprimant de prendre conscience qu'il y a de vraies solutions diponibles ici et maintenant ? L'excitation apocalyptique ferait-elle perdre à certains la capacité de calculer, de penser ? ...Etrange, en effet.
Je vous invite vraiment à lire intégralement cet article (du peak oil au Concentrated Solar Power). Je le trouve vraiment excellent.
