MSc. AEES Unit Presentation


Published on

The main thrust of this brief presentation, prepared for a module that counted towards my MSc. Architecture: Advanced Environmental & Energy Studies, was to question the wisdom of defending the coastline using large scale engineering defences, and to work with the changing coastline, questioning - should be laying the foundations for offshore wind farms, on shore in areas that we know are prone to flooding, when they are easily accessible. Discuss.

  6. 7. How the map of the UK could change in the next 30 years. Source: The Scotsman
  7. 8. <ul><li>Sir David King, the governments chief scientist was quoted saying to the BBC that “There are currently around £200bn worth of assets and 1.7 million properties in flood risk areas in England and Wales,&quot; </li></ul>
  8. 9. <ul><li>DEFRA [formerly MAFF at the time of publication] (2000) puts this in real terms as “1.8 million residences and 140,000 commercial properties equating to 4 - 5 million people that could be affected”. </li></ul>
  9. 11. <ul><li>Dr Tim Osborn Senior Research Associate from the University of East Anglia was quoted as saying : &quot;In terms of the science, the values are approximately right if the ice sheets do melt, with the exception of the last prediction. The question is whether these things are likely to happen or not.&quot; </li></ul>
  10. 12. <ul><li>“… there is often a public misconception that change at the coast can be halted through engineering works. There is often a demand to continue to “hold the existing defence line”, in order to protect assets, but this is coupled with an expectation that the shoreline will continue to look exactly as it does now. Due to the dynamic nature of our shoreline, this is incorrect in many, if not most, instances.” (ACAG 2004). </li></ul>
  11. 13. <ul><li>There is a tremendous difference in cost between “on-shore wind” and “off shore wind”. Currently On-Shore wind can be costed at $750 per kW whereas the cost for off-shore wind is $1800 kW (Anderson& Winne 2004). </li></ul>
  12. 14. <ul><li>Experience gained from Tuno Knob indicates that actual offshore wind energy output is 20-30% higher than from wind speed prediction models. …availiability has been higher than expected with an average of 98% being achieved. </li></ul>
  13. 15. <ul><li>AMEC Border Wind prepared a study that said we can produce 40% of UK energy needs by offshore wind power by 2030 by installing 2500MW each year. This would require 20 dedicated crane barges. </li></ul>
