Wind Energy

Australian idea for ammonia transmission of wind energy

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 Chin... »

wind turbine kW input when the wind isn't blowing, maximum output capacity, annual load factor and the

Dear Claverton, Below is a table of the complete fleet of eastern Australian wind turbines showing the maximum output capacity, annual load factor and the kW input when the wind isn’t blowing.  Some farms apparently have their own auxiliary power and don’t draw from the grid but in any event the drain on the grid is quite small. Regards, Leith Prof Leith A Elder BE PEng Principal Engin... »

Are 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 levels and the new build rate of new low energy buildings is too low to have any significant im... »

Offshore Wind Technology conference, 12 – 13 December, Birmingham, UK

 The Institution of Engineering and Technology (IET). The IET is one of the world’s leading professional institutions with over 150,000 engineers and technologists as members worldwide.  We are organising an Offshore Wind Technology conference, 12 – 13 December, Birmingham, UK and we would appreciate your support in promoting this event to your members. http://conferences.theiet.org/offshore-wind/... »

Effect of a step change in wind output or load on in grid frequency and control mechanisms

Fred, The frequency is system-wide. That is, all parts of an A/C system will have the same frequency. Any change in frequency is a reflection of a change in the balance between supply and demand. So a drop in frequency is a reflection either of a loss of generation, or an increase in demand. Actual demand at any time is a aggregation of many millions of demands, with all of us making changes, ever... »

Papers 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 welcome comments on these papers. (Please do not distribute them system... »

Didcot A Coal Fired Power Station – and potential impact of large wind energy on maintenance costs of two shifting power stations

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 over a ten year period with the last units coming on line in 197... »

Wind Energy Reduces Electricity Prices,Says Independent Study"….NOT

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 during periods of high wind. It is a sim... »

"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 over a 2,500 km ... »
