Ah sure, since I've invested more than half a million euros in the "green tech" studying it and draw my conclusions and they are far different from the current propaganda I have to shut my mouth. I can help actually, those who want that help, for instance suggesting to ARREST for crime against humanity top neoliberals in chiefs from G8/T20 to "World Government" [1] to top companies CEOs from pharma to energy stating…

Will be much cheaper by then provided society does not collapse first. If it does, replacing them will be among the least of your problems. Roving bands of supersonic aluminum Nazi hell zombies from beneath the hollow Earth may figure prominently among the latter. (Maybe they do already?) But securing dietary calories would probably present more frequent difficulty.

So your theory is "let's try and HOPE we will be able before the society collapse to make the new deal works"? If so consider a thing: that's a CRIMINAL act even in case of desperation. A society MUST never act without basis.

A company can, and individual can because there is a society around to help, the whole society can't because if something goes wrong there is exactly no one around to help.

In desperate cases desperate measures are meant to still reach a probable, defined outcome, like deciding to leave many alone, facing unrest etc BUT never hoping for something new to arrive in time: science and industry do not work like that and in general do work only when there are comfort condition for a long period of time.

Personally in case of a society collapse, knowing well we can't live in nature anymore, more than dietary calories I would seek revenge in the meat of those I consider guilty, the topmost figure I can reach with the most inhuman and fierce sentiment BTW...

Apart of that my point is simple: we have something that work, but is not sustainable since we consume resources more than natural reintegration rates. We DO NOT have alternatives so far. The answer must be try to discover them NOT try to push something we know can't scale nor work on scale nor reproduce itself.

With oil you can re-create oil industry. With nuclear you can't but at least you can made tools needed to re-create it. With p.v. and wind power you can't and you can't also create tools needed to re-create panels, inverters etc.

So far we know that we do not have nor we can't have in time a global superconductive hypothetical mega-grid to get stable enough energy supply because on enough part of the world Sun always shining and wind always blows. We do not have no viable solution for energy storage except for small scale needs for limited applications. Let's say we probably even can't have enough batteries to power modern homes for even a small fraction of the total population.

So the theory is: well, at least we can reduce energy consumption. YES, we can, with p.v. (wind provide too little and too inconstant power) BUT we can't connect it to the grid keeping the grid stable without a big and hyper-fast backup (lithium) and that's why originally BEVs was designed: to be always connected in large enough batches to compensate p.v. oscillations quick enough. UNFORTUNATELY so far:

- BEVs on sale have NO integration features for such use case, even for a personal scale like a domestic p.v. + the car as an extra battery talking to home inverters sucking power when the Sun shine, offering power when it's needed;

- nothing is even designed for a nation-wide smart grid;

- no electric appliance on sale is designed to be smart for p.v. integration, even those who actually claim the contrary.

So far we have NO smart-car battery chargers who talk a common and open protocol (let's say via canbus) allowing a human at home or in the car to state:

- charge car battery at {maximum,minimum} SOC {ONLY from p.v,also from grid to reach a minimum SOC at $TIME}

- car, do provide high voltage standard DC power to the home battery-charger/p.v. inverter as demanded not going below $SOC except in case of outage mode where the minimum SOC descend to near-zero.

Nothing is even debated about how to use privately owned cars to backup the grid providing relevant compensation for the service to their owner (please do not cite Tesla, they made proprietary stuff, innovative in general but of a so crappy quality that's a crime asking more than their production costs on sale).

So far no home appliance embed a standard protocol to be centrally controllable by a home server/solar inverter to do the ONLY current reasonable thing: p.v. self-consumption as much as possible.

Essentially anything on sale, sold as a commercial product, is more a dumb prototype made by some who do not even have clear ideas about it's usage. And you thing that's a "tremendous effort the humanity actually made for a better future"? Are you kidding? Let's start outline a real, resonate high-level overview plan instead.

I was giving a solution to the obstacle you pointed out. It doesn't get more relevant than that.

Sorry for my tone. Op mentioned someone doing a simulation that claimed that scaled up solar+wind+hydro generation with only 5 hours of storage capacity would be sufficient to meet the needs of Australia. That seems odd given that cloudy, windless conditions can last for days in many cases. You would at least need sufficient storage+hydro capacity to cover several days worth of shortfalls from wind+solar. Battery sys…

Green storage at scale does not exist yet because the equipment to do it has not been built yet.

The equipment has not been built yet because the factories to build it are still under construction, and because money is still overwhelmingly better spent building out renewable generating capacity needed to charge it from. Storage you cannot fill up is wasted money.

People responsible for keeping the grid operating are not at all worried about their ability to continue, using renewables and storage that will be built.

In places and times where renewable generation falls short for longer than local storage can cover, energy will be imported from places with an excess, via transmission lines or shipments of synthetic fuel, most likely liquified anhydrous ammonia. Until that is available in sufficient quantity, they will burn NG during those shortfalls. The amount burnt will be much, much less than is today.

Producing and then storing hydrogen underground takes very little of "hydrogen infrastructure". H2 may be generated, stored, and drawn down all within a single facility built over or near the underground storage cavity. The power involved may be moved in or out by transmission lines.

You are absolutely correct. Supply Chains are primarily fossil based and can NOT be substituted with low density sources like Green Energy or even electricity at all. For example, you can't efficiently make steel or most other metals with electricity alone. Even primarily electrically refined metals like copper or aluminum REQUIRE inputs that can not be made or refined or extracted with electricity. Often this is abo…

You can make steel with just electric heating - Swedish steel companies are making a lot of progress here https://www.reutersevents.com/renewables/renewables/sweden-l... Oil and petrochemicals have many uses and they will be with us for decades but at some point this century we will get the vast majority of our energy needs from fusion (the sun), hydro, wind and nuclear. It will likely take longer than we think and b…

however bad we will handle it, thee planet will be just fine.

global warming is problem not for the planet or nature, but for humans.

if all humans will die, and 99% of species die, planet will still be ok the nature will still live on.

just that our last record of existence for anybody else to find will be "we were stupid".

Jesus it's nice to read an informed comment on here. Yes, it's difficult to try to get these facts across to folks without them thinking you're a shill for big oil. It's especially sad/frustrating when people who claim to be engineers don't understand the engineering involved in the process of transitioning to green energy.

software engineer is not same as civil engineer. (i gues the capacity/abiltiy to learn is there, but still.. there is quite a difference)

If copper price is down, that means we have too much copper, not too little.

reading the post is essential. here is the bit adressing this: > that may be due to previous hoarding in China coupled with economic slowdown and/or disruptions in their metals markets

If you look at the copper futures chart the current price is below a few peaks but it is still quite high, historically speaking. That is in the face of a real estate crash in China and impending global economic slowdown(a significant portion of which is due to energy malinvestment).

On a related note, the majority of new home construction does not use copper these days(both for cost reasons and performance reasons).

+1000%

I'll admit to falling into the trap of thinking I'm smarter than everyone else, including domain experts outside my field of expertise, because I did well in a field very much devoid of actual, uh, engineering.

I thought the other poster's comment was relevant, so I didn't answer (I posted an earlier comment being replied to). FWIW, I instead would have suggested that natural gas could cover any shortages, since this type of power is easy to turn on and off, and fits more with the theme of "this is potentially possible today".

The simulation over produced energy from green source. Looking at the chart - looks like the wind power alone was enough to satisfy the grid if available. Given that, I do think it's possible that a mere 5 hours of backup can keep the grid 98% renewable, turning to hydro when solar + wind is not enough. Also solar / wind may be somewhat inversely correlated and north / south Australia also may have different weather patterns.

Given a large enough sampling of the world, I'd imagine it would be easier to find the wind / solar power you want, although politics could potentially make that harder.

The point is, they got the money, and were able to invest it. The same thing happens to wealthier people - if they invest the money unwisely, they lose it.

So if you started off poor, you have nothing to invest and you will be poor forever. Nice.

Are you even arguing in good faith? Do you think this encourages hard work?

You know what you are encouraging? Crime. Or a revolt.

Because thats what people do when they realise that playing fair won't let them get ahead.

> Nobody saves money in Scrooge McDuck cash vaults. All the money is invested, all of it. Russian oligarchs invested vast amounts of money into super yahts and luzury London real estate, which sits empty 360 days a year. Is that productive investment?

I bet you own some toys you don't use, too. A yacht and a luxury apartment ain't worth spit in the context of the global economy. Besides, they might be good investments.

The original question was - is the money in corporate warchests being used productively or is it lost to the economy.

Noone has demobstrated it is beong used productively. O am illustrating that some investments are terrible for the economy.

Google "climate change". Google "green energy". Google "decarbonization". Read up on them at Wikipedia. In the time you wasted typing up complaints, you could have become informed. Wasting your own time is foolish. Wasting others' time is an offense.

Offense is taken, not given. If you take offense to questioning the problem is yours and yours only. Why is it the replies to my questions do not answer the questions, instead saying 'google it'. How can google answer what is mean in that context, in that article? I have asked here on hackernews, and I have still not gotten an answer - only piffle: nobody has forced you to engage here, so don't spout nonsense such as…
