Dave Elliott: December 2014
http://delliott6.blogspot.com/2014_12_01_archive.html
Monday, December 1, 2014. In my last two posts I looked at the way changes in technology interacted with employment and at how green energy technology might create new jobs. That's part of a wider process of economic change. I want to round off this discussion with some more high kevel thinking, before I get back to my more usual focus of. Looking at what the technological options are. Maybe, for a while. But whether it can allow economic growth to continue unabated for ever is less clear. But there stil...

Dave Elliott: February 2015
http://delliott6.blogspot.com/2015_02_01_archive.html
Sunday, February 1, 2015. All change - as oil gets cheap. Being cut, the energy policy scene is getting increasingly fraught. Keeping OPEC oil production levels high has forced prices down as oil seeks to see off the boom in coal use. That in part has been due to the shale gas boom in the USA- which has been able to export more cheap coal. But these market manipulations are set in the context of climate change. That has had a big impact in Germany. Nevertheless, not everyone likes this trend anti-fossil ...

Dave Elliott: All change: new energy, new institutions
http://delliott6.blogspot.com/2015/05/all-change-new-energy-new-institutions.html
Friday, May 1, 2015. All change: new energy, new institutions. 8216;There needs to be some sort of regulatory overseer with clearly defined boundaries, given to it by, and answerable to, Parliament’. That’s one of the main claims of a discussion paper from iGov, the Exeter University based energy research group:. Http:/ projects.exeter.ac.uk/igov/working-paper-public-value-energy-governance/. 8216;better meets the technical and social needs of the evolving energy system’. They say they favour ‘a bo...

Dave Elliott: January 2015

Thursday, January 1, 2015. The Big issues: a communications revolution. Growing a peaceful, sustainable Earth through communications’. It’s good to start the New Year on a positive note! And the new revised edition of Gary Alexander’s. It is, as he says in the introduction, like the first edition. And in which all the other issues raised above were at least significantly better, if not fully resolved? What might it be like? What sort of jobs would people do? That’s a view that has been common in &#...

Dave Elliott: June 2015

Monday, June 1, 2015. Do you think there are many people of this kind, say, in England or in France? No; there are few who would be willing to break away from their employers and begin reconstructing the world.’. Joseph Stalin in conversation with H.G Wells in Moscow 1934 First published as a special New Statesman Supplement 27 October 1934. Recycled by NS 18/414. Is this the type of radical commitment that engineers must aim for? What are the practical implications? Thou shalt not use fossil fuels.

Dave Elliott: Nuclear in not the answer to climate change
http://delliott6.blogspot.com/2015/04/nuclear-in-not-answer-to-climate-change.html
Wednesday, April 1, 2015. Nuclear in not the answer to climate change. The land-use claim is familiar enough; but calculations like this often ignore the land use implications of uranium mining, fuel processing and waste disposal. Indeed, Amory Lovins has calculated that, when the fuel nuclear fuel cycle is included, the nuclear option overall may actually use more. Land than a renewable energy system with a similar output:.

Dave Elliott: Climate Changes again
http://delliott6.blogspot.com/2015/07/climate-changes-again.html
Thursday, July 2, 2015. It is incontrovertible that the climate is changing, and the cause seems clear- emissions of greenhouse gasses due to human activities including burning fossil fuels. However the scale, nature and pace of the changes, and their likely specific local impacts, are still. But that is not certain. There are problems with this. Will adaptation be enough and will it be cheaper than major mitigation measures? However there is another, arguably more nuanced approach- don't rely just on co...

Dave Elliott: September 2014
http://delliott6.blogspot.com/2014_09_01_archive.html
Saturday, September 13, 2014. There is a fascinating debate over whether long distance High Voltage Direct Current supergrids. Are the right way ahead for energy transmission. In theory they allow variable local supplies. And demands to be balanced across wide geographical areas and are much more efficient, in terms of energy losses over long distance transmission, than. However there are problems. It can get quite technical. At the extreme is the idea of local ‘island generation’, with each ...To shift ...
