\"walney<\/a>Could wind power the world?\u00a0 That’s the claim made in a new report from the International Energy Agency (IEA).\u00a0 The IEA got Imperial College London to do the analysis.\u00a0 They reckon that that offshore wind could meet more than 18 times our current electricity demand worldwide, that is 420, 000 TWh per year.\u00a0 The IEA also claim that offshore wind matches the capacity factor of gas fired plant for electricity generation, is less variable than solar PV and therefore is suitable for baseload generation.<\/p>\n

There does seen to be something in this.\u00a0 Offshore wind even a couple of years ago was regarded as extremely expensive.\u00a0 Costs have plunged and the generation levels have proved better than thought.\u00a0 In our book<\/a> we were relatively cautious about the technology, largely due to the costs at that time.\u00a0 These have fallen.\u00a0 David MacKay was very cautious in his book “Sustainable Energy \u2014 without the hot air”.\u00a0 He lowered the resource to a third of the area available.\u00a0 The Centre For Alternative Energy have given offshore wind a higher total than us or David MacKay.\u00a0 It does seem that we may have underestimated the potential.\u00a0 The IEA have ignored places with windspeeds of less than 5m\/s and large chunks of offshore capacity where there are other uses such as marine parks.\u00a0 There is one however one change that might explain some of the increase the capacity.\u00a0 That is floating turbines.\u00a0 These are tethered to the seabed and not fixed.\u00a0 This increases the potential ocean areas massively where turbines can be sited into deep water.<\/p>\n

A few caveats.\u00a0 No one least of all the IEA is suggesting we just use windpower to electrify our world.\u00a0 There are times when the wind drops and the resource may not always be in the right places.\u00a0 Nevertheless this does show that even if only a half or a quarter of the potential capacity could be utilised the resource is huge.<\/p>\n
