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 […]

Effect 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 […]

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 […]

The value of electricity storage to the UK power system

Dave,   I’ve got around to looking at the value of storage and have prepared a simple model to assess this for the GB system, copy attached (in Excel 2007 containing a couple of macos).    I’ve taken some sample days of historic price profiles from the www.bmreports.com website – two for each month of […]

A manufacturer claims "the pulsed meter output facility is an essential part of meter technology and should be preserved, not blocked as OFGEM is permitting the Energy Companies to do".

CAMPAIGN TO SAVE THE PULSED OUTPUT METER  FOR THE SAKE OF UK PLC Summary: 50% of electricity and gas used in building is used in small quantities and metered through low volume non Half Hourly registering meters – as per your house which are read every 3 months roughtly, and hence are  quarterly year metering .
