Jeezuz your hard work, go troll somewhere else muppet.
Obviously the remedial English isn't working, you still can't string together a sensible sentence, let alone a sensible cohesive discussion.
So sending coal to Ukraine is corruption? What are you on about?

I used to get that back in 2010, in Perth, but it is good money.
You invest it wisely and you could retire at 55, like I did.

Energy Efficiency No 1
If you havn't heard of Amory Lovins this article is an excellent introduction. Amory was one of the earliest practical advocates of energy conservation. A number of very striking stories in this article. Check it out.

One of the leading advocates of energy conservation explains why this could be a turning point for climate economics
Sat 26 Mar 2022 08.00 GMT
Temperatures dropped far below freezing this week in Snowmass, Colorado. But Amory Lovins, who lives high up in the mountains at 7,200ft above sea level, did not even turn on the heating.
That’s because he has no heating to turn on. His home, a great adobe and glass mountainside eyrie that he designed in the 1980s, collects solar energy and is so well insulated that he grows and harvests bananas and many other tropical fruits there without burning gas, oil or wood.
Nicknamed the “Einstein of energy efficiency”, Lovins, an adjunct professor of civil and environmental engineering at Stanford University, has been one of the world’s leading advocates and innovators of energy conservation for 50 years. He wrote his first paper on climate change while at Oxford in 1968, and in 1976 he offered Jimmy Carter’s government a blueprint for how to triple energy efficiency and get off oil and coal within 40 years. In the years since there is barely a major industry or government that he and his Rocky Mountain Institute have not advised.
....The prize for governments wanting to be truly energy efficient is huge. Lovins and RMI have calculated that at least two-thirds – and probably as much as three-quarters – of all fossil fuel-generated energy could be profitably saved in most industrialised countries, and even more in developing countries because they tend to be less efficient to begin with and can more easily build things right than fix them later.
..The future must be in the mass retrofitting of buildings with insulation and heat pumps and what he calls “outsolation”. “You can design out the pipes by putting a sort of tea cosy around houses, like the Dutch Energiesprong exterior retrofit. They can superinsulate your house to net zero standard in a single day whilst you’re at work, and meanwhile they’ve dropped in a very efficient heat pump core for mechanicals, and put on a super-insulated solar roof. And when you get back, you pay them rather than your energy companies.”

And interview with Amory and Hunter Lovins in 1984. Well worth checking out.
I will post the refrigerator story.
Amory and Hunter Lovins: Spokespersons for a Sustainable-energy Future
STAFF PHOTO
While many of us dream about an America that runs entirely on efficient, clean, renewable sources of energy, Amory and Hunter Lovins are doing a great deal to help bring such a future about. Indeed, as authors of some of the most important works in the field and consultants to governments and utilities, they are without doubt our nation’s most effective spokespersons for a sustainable-energy future.
A PARABLE
Do you remember the pre-World War II refrigerators that had the motor on top? Those motors were close to 90% efficient. These days, refrigerator motors are more like 60% efficient. They’re also underneath, so the heat rises to where the food is. Thus, with the blessings of modern technology, refrigerators now can easily spend half their effort taking away the heat of their own motors!
Over the years, the manufacturers have also been trying to make the inside of the refrigerator bigger without making the outside bigger. (Given time, I suppose they would have had the inside bigger than the outside.) What they did, of course, was to skimp on the insulation, so outside heat comes straight in through the walls. They also designed the refrigerator so that when you open the door, the cold air falls out and the refrigerator frosts up inside. Most refrigerators therefore have electric heaters inside them which go on now and then to melt the frost. Many also have electric strip heaters around the door to keep the gaskets from sticking. Some even have electric heaters in their outer skin to keep humidity from condensing on it!
You can try if you like, but it’s hard to come up with a dumber way of using electricity. Yet if you don’t use electric water heaters or space heaters, refrigerators are probably the biggest single part of your household electric bill. Nationally, they use the equivalent of about half the output of all nuclear power plants.
Fortunately, there are smarter ways to build refrigerators. Consider how many kilowatt-hours it takes, for example, to run a typical refrigerator for one year. From 1950 to 1975 that electric demand nearly trebled to 1,800 kilowatt-hours per year. Then in 1976 California passed a law saying that you couldn’t sell a refrigerator there that used more than about 1,400. Within four years, virtually every refrigerator on the market met that standard, and the best — by Amana — did a third better. Meanwhile, the government was told by consultants that better motors, insulation, gaskets, and so on, could reduce the demand to 650 kilowatt-hours per year. Sure enough, by 1981 a typical machine on the Japanese market used only 700, and Toshiba’s best used only 550. The consultants now went back to the drawing board and concluded that by pulling out all the stops they could get it down to about 420; but a Danish engineer showed that 260 would be highly cost-effective. Upsetting all these theoretical estimates, a California engineering designer — Larry Schlussler — built a refrigerator in 1979 that used 288 kilowatt-hours per year; he is currently selling a handmade model that uses 175; he built a prototype in 1982 that used only 64; and his 1984 prototype uses 15. Furthermore, the passive refrigerator we’re building into our zero-energy house in the Colorado Rockies will use only about half a kilowatt — hour per year-to run the light that goes on when you open the door!

Energiesprong (‘energy jump’) is finding ways to make buildings more efficient without requiring major construction projects.
The problem in Australia houses are built for aesthetic appearance and not for energy efficiency, even the way a suburb is subdivided is done to maximise the land value, with no regard as to the block orientation to allow for the building to be constructed to face in the optimum direction.

We are living through a revolution in energy policy in Australia. I cannot recall when last I sat down to write a column with as much relish as this one.
On the other hand it's a 4 wheeled car with only two wheels and that's a fatal flaw.
9GW of wind farms will indeed generate rather a lot of energy over any given time period. No dispute there. What they won't do however is do it constantly. Offshore wind might be more reliable than onshore but it's still nowhere near constant.
Now for the problem.....
The author of the article admits that building onshore transmission lines is facing problems gaining a "social license" and he seems opposed to building additional transmission between Victoria and Tasmania at all.
So what's the plan for when the wind isn't blowing?
That's what frustrates many about all this. Glowing articles saying how great it all is but with a fatal technical flaw in the argument that's completely ignored.
In the absence of building deep storage in Victoria, or building transmission to such facilities to be built in NSW or Tasmania, that gives rise to a situation where Victoria's left with two basic choices - fossil fuels or darkness.
What saddens me most is that the Victorian Energy Policy Centre is based at Victoria University. So we have a rather lamentable situation of a university failing to pick up on something that the average high school student would identify, that wind does not blow constantly.

Frankly I just can't believe that the issue of sufficient energy storage in some form is not going to be a part of this development. As you point out ensuring effective use of all power and ironing out down time is non negotiable.
Let's see if there are additional plans along these lines. The article I posted at 5747/8 explores some options.

Advanced inverter technologies have taken centre stage in a detailed roadmap put together by the CSIRO and the Australian Energy Market Operator that plots a path to a zero emissions grid and a 100 per cent renewable electricity supply.
“The pace and scale of this transition is extraordinary,” said AEMO’s head of operations Michael Gatt. “It demands new approaches to power system operations including tools, technologies, process and platforms, which complement network planning, and market and regulatory reforms.”
Chief among these are advanced inverters, also known as “grid forming inverters”, which have the potential to provide many, if not all, the grid services currently the province of spinning fossil fuel generators.

AGL's Loy Yang power station. Credit: John Englart
Mike Cannon-Brookes certainly created headlines recently, teaming up with Brookfield to propose an unsolicited $8 billion joint takeover bid of AGL Energy, mooted as an effort to speed up the closure of the gen-tailer’s coal-fired power plants well ahead of schedule, from 2045 to 2030.
The prime minister came out and claimed that the early closure of the plant would increase power prices significantly, while reportedly reserving the right to block the move under a national interest test to protect Australia’s energy supply.
Talk of a potential blockage of the takeover, however, runs counter to the very notion of market mechanisms driving change. Furthermore, it ignores the economics which would drive someone like Cannon-Brookes, with the backing of investment behemoth Brookfield, to make a move of this size.
He’d crunched the numbers, as would have Brookfield, and seen that not only was this the right move, but one which would make money. The consortium believed it could accelerate the transition and make money at the same time, and in turn provide lower electricity prices for all.
The truth is that the economics make sense to everyone involved in the push, and the country’s energy supply would not be at risk. Furthermore, the closure of a coal plant is hardly anything new; in fact, it’s inevitable and, for many, just around the corner

It's pretty much the issue that's causing frustration among those looking at it professionally or otherwise in a serious manner.
It's a fact that the data's very clear, as per charts I've previously posted, that we do get periods involving multiple consecutive days of low wind + solar yield. It's not a hypothetical, there's an abundance of data from real wind farms and solar facilities, plus Bureau of Meteorology data, plus data captured by others and it all tells the same story.
In terms of data, there's more sources than many would assume.
Bureau of Meteorology is one obviously.
Existing wind and solar farms are another. Bearing in mind that includes operations on the Bass Strait islands which, whilst small scale, do provide data on performance at any given time.
Monitoring set up specifically with a view to wind farm development is another, noting that in the context of Victoria and Tasmania this goes back to the 1980's.
The oil companies have also collected weather data at some of their offshore operations, noting that some of these are reasonably close to the likely location of offshore wind farms.
Also shipping. Whilst not their primary function and not in a fixed position, apparently they have indeed kept records of weather conditions. That's still some useful information especially when it's the same ship sailing the same route at the same time each day.
Put it all together and there's no doubt as to the need to either store energy or have a backup, the only real question being how best to do it.

Not much solar would have been generated in Qld over the last few weeks.
This is the sort of climate change stuff that will have to be dealt with in a 'renewable environment'. That's the thing that most Greenies don't understand. There will have to be on call power to fill in large gaps that batteries can't.
