I very much recommend reading this article http://www.europeanenergyreview.eu/site/pagina.php?id=3740&zoek=Vahrenholt on european energy review which features a (rather lengthy) discussion between climate scientists Rob van Dorland and Bart Verheggen and self-proclaimed climate expert Vahrenholt. While Vahrenholt was mainly backed by German Bild Zeitung (crappy German tabloid), van Dorland and Verheggen have a list of serious scientific papers […]

Read Morewind 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 […]

A 120 Nm³/h, with a max output of 50kVA/ 40kWe (120kWe), or 180kWth 2. A 180 Nm³/h, with a […]
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 MoreGREENING THE DESERT Andrew McKillop
In the real world, the non-polar deserts are growing at a rapid rate, totally overwhelming the small but valiant attempts at pushing them back. http://hqweb.unep.org/geo/GDOutlook/ One neglected cause among many includes the annihilation of tropical forests. These contain 600 billion tons of carbon, equivalent to about 4.6 trillion barrels of oil or 145 years […]
Read MoreBurning wood has worse carbon emissions than burning coal
Some thoughts about current Bio issues. Whilst there are some good reasons to produce biogas from wood when you analyse the process on an exergy basis it is inferior to the combustion of the wood in large scale CHP as practiced in Copenhagen. The reason the work done by the Carbon Trust signalled that AD […]
Read MoreClimate change discussion, OECD report, CCS
Hello all The OECD’s report on the global environment to 2050 (available to buy or read online free at http://www.oecd.org/document/11/0,3746,en_2649_37465_49036555_1_1_1_37465,00.html) includes a summary of where we are at with emissions trajectories at the moment. On the current path, 85% of energy will be provided by fossil fuels in 2050, with an estimated atmospheric CO2 concentration […]
Read MoreThe stupidity of mass burning of biomass to replace coal.
From the Claverton Gmail threads: Dear all, David Weight kindly copied me in to this thread. I hope you don’t mind me adding my thoughts. I am only going to comment on the use of biomass for electricity-only, and not the question of DH and or CHP. My position is that UK, EU and US […]
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 […]
