25.01.2022 The LNP has been calling for regions with no active coronavirus cases to be fast-tracked through the recovery roadmap and eased out of restrictions for weeks no...w. Queensland is a big state and a one-size-fits all approach doesn’t cut it. Annastacia Palaszczuk’s blanket restrictions across the whole state are killing jobs and closing businesses in Cairns, Townsville, Mackay and the Whitsundays. The Premier needs to back down before she delivers a devastating blow to our tourism industry. Annastacia Palaszczuk is the biggest roadblock to Queensland’s economic recovery.

22.01.2022 95 kW Grid-Connect PV project underway

22.01.2022 COVID-19: The JobKeeper will be useless to most WA businesses. The income test is based on comparing to the previous period 12 months ago. After slowly coming out of very low trading in Western Australia most businesses will have an increase in business compared to the appalling low turnover one year ago.

21.01.2022 JustFYI: This is a link to the Google "open letter" to you and me - concerned about changes to laws in Australia. I present this without further comment. https://about.google//ALL_au/google-in-au/an-open-letter/

21.01.2022 How much longer before this stupid dangerous Roof Top Isolators rule is FULLY REMOVED. -- There is no technical way to safely house and seal these RTIs for 25+ years. -- there is NO BENEFIT to safety having RTIs -- RTIs are a stupid dangerous fantasy... https://www.abc.net.au//solar-fire-safety-concer/13115618

20.01.2022 end of report: "there is no way to RECYCLE lithium batteries! we are WORKING ON IT !! " NOW THEY TELL US!!

17.01.2022 Always useful information on Solar Quotes website. Useful reference material if read carefully. We do not endorse Solar Quotes, but it is a useful source, a great way they have used the net. https://www.solarquotes.com.au/inverters/

12.01.2022 Is anyone else having problems with the Australian Standards DRM (document rights management) ??? Buying through SAI Global - their support people have been unable to solve - "paid-for" files will not open HELP

05.01.2022 Keeping the Lights On - with renewables: (some common sense, a semi-technical article) QUOTE:... Power system design can be extremely complex but there is one simple number that matters. It is a big, bad number. To my knowledge this big number has no name, but it should. Let’s call it the minimum backup requirement for wind and solar, or MBR. The minimum backup requirement is how much generating capacity a system must have to reliably produce power when wind and solar don’t. For most places the magnitude of MBR is very simple. It is all of the juice needed on the hottest or coldest low wind night. It is night so there is no solar. Sustained wind is less than eight miles per hour, so there is no wind power. It is very hot or cold so the need for power is very high. In many places MBR will be close to the maximum power the system ever needs, because heat waves and cold spells are often low wind events. In heat waves it may be a bit hotter during the day but not that much. In cold spells it is often coldest at night. Thus what is called peak demand is a good approximation for the maximum backup requirement. In other words, there has to be enough reliable generating capacity to provide all of the maximum power the system will ever need. For any public power system that is a very big number, as big as it gets in fact. Actually it gets a bit bigger, because there also has to be margin of safety or what is called reserve capacity. This is to allow for something not working as it should. Fifteen percent is a typical reserve in American systems. This makes MBR something like 115% of peak demand. We often read about wind and solar being cheaper than coal, gas and nuclear power, but that does not include the MBR for wind and solar. What is relatively cheap for wind and solar is the cost to produce a unit of electricity. This is often called LCOE or the levelized cost of energy. But adding the reliable backup required to give people the power they need makes wind and solar very expensive. In short the true cost of wind and solar is LCOE + MBR. This is the big cost you never hear about. But if every state goes to wind and solar then each one will have to have MBR for roughly its entire peak demand. That is an enormous amount of generating capacity. Of course the cost of MBR depends on the generating technology. Storage is out because the cost is astronomical. Gas fired generation might be best but it is fossil fueled, as is coal. If one insists on zero fossil fuel then nuclear is probably the only option. Operating nuclear plants as intermittent backup is stupid and expensive, but so is no fossil fuel generation. What is clearly ruled out is 100% renewables, because there would frequently be no electricity at all. That is unless geothermal could be made to work on an enormous scale, which would take many decades to develop.
