There is no such thing as an independent anything anymore (if there ever was!). All reporting, all research, and everything else is driven by some person or group with an axe to grind. It takes a...

But why does the price go negative? Oversupply reduces the price, but in no other market that I can think of does the price go negative. The answer, I suspect, is twofold. Firstly, unlike any other...

I don't really understand why this is the case. I realise that during the day there is an abundance of energy, but the concept of having to pay to stay online seems like an artificial construct - how...

That building is fabulous. Most countries would have built the cheapest, ugliest building possible. Not Norway!

And even though we never get snow, I want a set of those tracks for my quad bike!!

I've never been to Norway, but much of what I've read, and discussed with various people over the years, suggests that they have a very different outlook from much of the world. I have postulated...

There is a fuel tax rebate (20c/L ish, depending on the situation) for commercial road use of diesel. If we regard that as a rebate against the excise, which is 50c/l odd, surely that knocks nearly...

This ABS page, in the total fuel used graph, suggests that passenger vehicles use more total fuel than haulage, whilst I have no doubt that trucks do far more damage. The road on which I live has...

Indeed. But they might get photographed planting a tree. That'll help.....

I don't know what the Tesla semi will cost in Australia, but normally we can more or less double the US price for most things (at least that is my experience). On that basis, the Tesla might cost...

Whilst I have no doubt that everything you have said is correct, have you calculated how much it would cost to replace all the trucks that currently carry that freight with (for example) Tesla semis?...

The Rav4 has a similar system, it's very useful but also relates to what I was saying about the life of these modern vehicles (EV or ICE). The front camera on the Rav4 is very exposed to stone chips,...

It probably varies with route and driving style, and they drink more at higher speeds - I've seen figures as poor as 160l/100km quoted. The guy I was talking to has several trucks and we were...

I must admit that I do like the sound of a sporty petrol engine, but it wouldn't stop me buying an EV. Apparently I'm not alone in that "like", because I saw an ad for an EV yesterday on the TV, and...

For commercial transport, you require abundant energy to drag a 55tonne B-double hundreds of kilometres across the country, and you can't sit around waiting for it to recharge. You also need to...

Absolutely, but the "bottom line" is ongoing - a short term loss is often a required and acceptable penalty to ensure future profitability. At present I'm struggling to see any effort being put into...

This is not strictly true. The Directors of a company can do pretty much whatever they like, if it's "in the best interests of the company". They can be removed by the shareholders, but that requires...

Is this denial of the way the world is going, or some hope/belief that there will be a U turn, or have they simply made a decision to "take the money and then walk away"? Or something else entirely?...

I'm confused by this. The problem is that a coal fired plant can't be switched off, so in times of oversupply it remains running. During that time, it's releasing the same amount of CO2 whether its...

Sabine Hossenfelder has a video on Youtube about hydrogen. If I remember correctly she wasn't massively hopeful, though it was a while ago that I watched it.

Just a thought.... I believe Amber has an API to access their current price (and historical, forecast etc.). If the prices are now regularly going -ve, could you not leverage that API, using Home...

I understand. What I don't understand is how we will ever transition to renewables under those circumstances. As you say, solar is for a limited time each day, and (from experience) on a cloudy day...

Indeed. OTOH, do we have any real idea of what storage capacity might be required?

My assumption has always been that we'd have a massive oversupply of renewables, such that (very simplistically)...

Yep.

And in addition to these, ahem, less upfront processes, some fairly major projects have been undertaken worldwide. My point was that in a city faced with the need to build desalination plants and...

I do have an Australian Army Perentie in my collection, and if I could buy an ex-military underground bunker in the middle of nowhere, I'd be living the dream! It'd be even better if Woolworths and...

In the eastern suburbs of Sydney we know people who have done "renovations" (basically knock down your house a build something waaaay bigger) that cost, in some cases, millions. The new houses have...

Surprisingly, yes. Not just the chemistry (soil balancing etc., I actually did some extra courses), but also simple analytical thinking. After being an industrial chemist, I moved into IT and ended...

By the way, for anyone new to the thread, I am not a climate skeptic. I use zero grid power or water, and grow an increasing amount of my own food (now that I have time!). I do not have an EV,...

Twofold, I guess.

Firstly I think it is wise for all of us to THINK about things. Not just climate, but everything. It is very easy to be led around, to believe what we are told without ever...

I'm not really defending a position, I'm simply having a conversation and, in part, questioning blind obedience to a cause.

The difficulty with things like declaring an increasing number of...

I'll continue to play Devils Advocate......

Is it really the case that the weather is getting wilder? Or is it that we notice things far more when our attention is drawn to them by outside...

Absolutely! So now we're back to my original issue - if profit is the motive, how can we tell what is genuine as opposed to what is in the interests of the person "telling the story"? This applies to...

Ouch!

I found the number of REC Registry notifications to be quite alarming at times, and it's one of the main reasons why I'm sceptical about "profit" being a good driver in this area. That, and...

From that article it appears that they have a higher energy density than lithium, but a very low power output. From what I can see, a Tesla 5.3kW module is rated at 1000A for10 seconds (or maximum...

I'd really prefer to think it wasn't true either, but everything I see suggests that it is. How many people have actually given something up, or changed their lifestyle to adopt a better approach?...

It's a very interesting question, isn't it? The climate scientists with "very little power". Really? 40 years ago nobody had heard of "climate scientists", and indeed they had zero power. These days...

It has been mooted in conversation several times that this is conclusive proof that climate change is a con. The logic goes that if the people in power, those with all the knowledge and wealth, do...

I wonder how long that will continue to be the case. Presumably (?!) there will come a time when imminent death trumps the profit motive..... or maybe we simply fry, choke on fumes or whatever whilst...

Jumping, yes absolutely.

I never had any problems with goats chewing wires, possibly due to our extensive usage of electric fences - they learnt very young to keep away from the fences!...

I've worked sheep with both Kelpies and Collies, but never in an area where I 100% can't see what is going on. I've never been in a solar farm on foot or bike, but from the outside it looks like...

I suspect that making the co-existence easy would require the system to be designed that way in advance, rather than simply shoving sheep under existing panels. I also suspect that the optimal...

1/ Both sides seem to always conclusively "prove" that they are correct, yet both seem to cherry pick and ignore reality. For example, the CSIRO report mentioned above - does anybody really think...

Is "Fedferal Government" (third paragraph in the document) a political statement or a typo, do you think?

Only if we assume the required changes don't involve "us" making changes directly. The generation, storage and transmission of power are controlled by the government and large corporations, but the...

I have absolutely no doubt that the earth will survive. Whether humans (or our current civilization) survive is an entirely different matter, and one in which I suspect climate is only a small part.

Tongue firmly in cheek.....

Another way of saying that, is that on a planet that is 4.5billion years old, we've taken measurements for 40 years and decided to panic......

It's not that I don't...

That was the way I was trained, and I fully agree with the sentiment. Sadly, at the present time, when "you can't argue with the science" seems actually to mean "if you disagree you'll be ridiculed...

I'm starting to think that my experience with science and scientists is very different from that of other people! I was trained as a chemist a long time ago, and that training included various...

Playing Devil's advocate for a moment, I'm always a touch sceptical of these temperature numbers. When I was trained as a scientist (industrial chemist) many years ago, we were taught that for...
