https://mail.google.com/mail/?shva=1#inbox/1384c714ccc80b76 takes you to mail with file attached… ——– Original Message ——- I am wondering if you all might be interested in a proposal I am pushing in Australia that might also be relevant to other places with renewable energy resources in remote areas such as in North Africa, the Middle East, desert areas in China […]
Read MoreAre large thermal stores and Combined Heat and Power District Heating (CHP) with District Heating (DH) pipes to deliver heat to buildings is more likely to be a better solution to de carbonising the building heating sector than relying on large-scale electricity storage of renewable or nuclear electricity (the “all electric solution”) delivered to buildings via cable?
One of the most intractable energy problems in Europe is how to deal with the heating load of buildings, (11 EJ/y), which is the largest user of primary energy and is presently met largely with gas. This heat load will not go away due to the expense of insulating the legacy buildings beyond quite modest […]
Read MoreEffect of brutal cutoff of wind capacity – Spanish Wind ramping, intermittency back up
http://www.carboncommentary.com/2009/11/15/853 Spain’s variable wind and stable electricity networks Sunday 15 November 2009 in uncategorized by Chris Goodall One of the frequent criticisms of wind energy is that national distribution systems (‘the grid’) cannot cope with large number of turbines because of the variability and unpredictability of their output. Grids need to match supply and demand […]
Read MoreIs nuclear power flexible, does it have load following capability?
Some Notes on the Flexibility of Nuclear Units What is “Flexibility”? What does “flexibility” mean for a generating technology? I guess that most people would think about the ability to increase or decrease active power output (Megawatts) either on instruction, or automatically, in order to help balance generation and demand on the system. But the […]

Read MorePapers in Energy Policy from Mark Delucchi and Mark Jacobson, Stanford / California University USA – 100% renewable energy at reasonable prices and timescales
Mark Jacobson and Mark Delucchi recently published two papers in Energy Policy expanding upon our article on 100% wind, water, and solar power for the world, published in Scientific American in November 2009. I am attaching corrected in-press proofs of the articles. Mark and I continue to work on various aspects of this, so we […]

Note: Some notes have been added, via the comment field which originate from the Claverton emails, from authoritative persons, which inter alia indicate that the maintenance and operating costs for a plant such as this are slightly less than 0.4p/kWh. Background and Location Didcot A is was built as a coal fired steam power station […]

Prospects for Trans-Atlantic Undersea Power Transmission harryc@ontarioeast.net Submarine Power Cable Precedents: For several decades, submarine power cables have carried electric power across short distances under bodies of water within the same nation. Some examples include the cable from mainland Italy to the offshore Mediterranean islands of Corsica and Sardinia. Similar cables were installed in Sweden, […]

Extract from Claverton Energy Group Archives, by Paul Frederik Bach, ex director Danish Western National Grid. On 12 May 2010 21:13, Paul-Frederik Bach <pfbach@profibermail.dk> wrote: Dear all, The debate on the economy of wind power seems to be never ending. Observations of wind power output and spot prices indicate that wind power creates low prices […]
Read More"Electric power from offshore wind via synoptic-scale interconnection" – using HVDC interconnectors to smooth intermittent power
Abstract World wind power resources are abundant, but their utilization could be limited because wind fluctuates rather than providing steady power. We hypothesize that wind power output could be stabilized if wind generators were located in a meteorologically designed configuration and electrically connected. Based on 5 yr of wind data from 11 meteorological stations, distributed […]
