Getting the assessment of technology right: Severn Barrage or other tidal energy extraction methods for instance

No comments:
Its now emerged that alternatives to the 10 mile long Severn Barrage proposal will also be examined as part of the 'barrage' feasibility study. This is good news, though its a concern that the big barrage, and all the profit-loaded development that comes with it, is what is obviously being favoured - boosting renewable energy supply and energy security, with minimal impacts should surely be the uppermost consideration. Interesting that Labour's Cabinet Minister for Business...John Hutton chose to announce the barrage study in the middle of a party conference, getting lots of media coverage and 'green' kudos, instead of waiting for the Sustainable Development Commission to report (which it will this Monday!!).

Its vital that we get the technology assessment right, to establishment the proposal with the best combination of benefits, especially renewability, security and low impact (they could do a lot worse than seeking OU advice !). The assessment should, for all alternatives, look at: cost-effectiveness now and on into the future; technical capabilities and limitations; impact on the economy and working lives now and on into the future; impact on the natural environment and other system environments now and into the future.

I'm strongly of the opinion that we are far too 'energy generation obsessed' and are seriously under-investing in far less sexy but much more sensible energy efficiency and conservation. This, as the cheapest, quickest and most effective way to fight climate change, by orders of magnitude, should really be the basis of energy policy.

Disease spread - a not so widely discussed aspect of climate change, until now...

Climate change has a wide range of serious health implications both for people and other animals, including enabling diseases to spread more easily.

A worrying story about African Horse Sickness in todays Bristol Evening Post (in a section where I dont usually find that much to read). This sickness is related to Bluetongue disease which has just arrived in the UK for the first time, and which we so far have seen 11 confirmed cases of. Horse owners are understandably concerned that we should be prepared for the imminent arrival of African Horse Sickness, which is spread by midges as Bluetongue is.

Climate change is certainly in the picture as one reason why Bluetongue has spread northwards across the globe, through Europe to the UK. The virus is transmitted by midges more effectively in warm, moist conditions. (A cold winter might drastically reduce the virus but we dont have many these days).

Its also possible that globalisation is a contributory factor, helping virus-carrying midges to spread as people and goods travel more and more across the globe more and more frequently.

The consequences for animal welfare are significant, as are the costs and stresses on farmers, particularly as we still have foot and mouth problems. The appearance and spread of African Horse Sickness could be devastating to the equine industry.
