The industrial revolution and the beginnings of a global liberal trade order pretty substantially changed the shape of the world's economic system, even if sometimes people call predecessor systems like mercantilism a kind of capitalism. But if you want to extend the time horizon to 400 years (ie. to the beginning of the end of feudalism) that's still not that long in the grand scheme of things. That said I don't rea…

Mercantilism definitely is NOT a kind of capitalism. Adam Smith and other thinkers during the Scottish Enlightenment were specifically arguing against mercantilism. The Cron Laws in England were even successfully repealed by on of Smith's students.

I mean, I agree with you (I just said sometimes people call it that, not that it is that) but I don't think anything you said really contradicts it being a kind of capitalism. After all Lenin and Stalin and Trotsky disagreed literally violently with each other but Soviet Communism is still a label that contains all their efforts and systems.

I'm honestly tired about PR positions written or referring some beancounters ideas of the world, regularly completely detached from the real world.

Personally, smelling rodent early enough I've built a new home, airtight as needed/possible, well insulated, with a (still rare these days) heat-pump VMC, other heat-pumps for heating (water-water) and hot sanitary water (air-water), a small p.v. plant with lithium storage enough to being fully autonomous when heating is not needed and partially autonomous in winters months: the result is simple autonomy is not achievable, nor real economy to pay back the huge investment.

I mean, I do not invest to earn in money but to guarantee comfort of life in "bad water" expecting unreliability and high services prices, but in monetary terms it's a TOTAL FAIL. Heat pumps can potentially last around 10 years, lithium battery being used very little (daily 15% authorized DOD + eventual blackouts) perhaps the same. Inverters probably can last more, so solar panels, but they'll probably be not much interesting to keep after that amount of time. Long story short ~60k€ for just 10 years of usage. Even with ARTIFICIALLY skyrocketed prices (which is a crime against humanity than in Democracy demand justice, like life-long sentences, outside Democracy demand simple brutal revenge) economically is a total fail.

If I add a BEV to the mix is even worse: so far NOTHING is really designed to work on p.v. so even being a WFH worker, so able to recharge a car at home when the Sun shine witch might be most of the time, NO DAMN VEHICLE on sale offer a standard data port to talk to a p.v. invert and get ONLY available power from the Sun like stationary BMS/batteries do (so something we already have at commercial level of evolution), equally almost no vehicle can act as a battery to the home, very few offer a 240V AC inverter with 3kW maximum but NOTHING really integrated nor integrable. Similarly the same happen for hot water where only few systems offer modbus PARTIAL control of the system from a central energy management device witch is normally something home-made since on sale there is again essentially ZERO to really try the self-consumption route. Why such route? Because is the only meaningful choice technically speaking.

Yes, you are reading correctly: keeping a national grid stable with big p.v. plants it's simply IMPOSSIBLE until we get superconductive global grid (and I'm not sure if it's possible in that case either). AC national grids are designed to sustain a slowly changing mean load, when the load change fast controlling the grid frequency is a nightmare. That's why the big push to BEV dreaming an surrealist scenario of soooo many connected batteries on wheel that keep regulating the network frequency or offload such tremendous costs to individuals.

Those who really think we can run NOW/in a decade the world on renewable can be classified in two categories: dreamers completely outside the real world, not much different than children dreaming Star Trek or CRIMINALS who try a hyper-big scam fully know the outcome. You do not have to believe but to know, so since we are on HN just try to design/outline such renewable economy being honest.

Garbage comment from an uninformed SW engineer: How, in the current economic and geopolitical environment, can they project that production costs will continue to decline? Green tech requires massive amounts of dirty energy to produce. It also has been benefiting from globalization which is now going in reverse. I would add at least 5 years to any timeline given because of the recalibrating global energy and material…

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 about chemical reductions that required carbon or other reductants that can't be effectively or efficiently made with electricity. The most obvious one is silicon - carbon reduction of SiO2 is the only and best efficient refining method (1st stage only - you need further far more energy intensive refining to make semiconductor-grade silicon).

Recently brought up in Congress was questions of how petrochemicals are to be produced if the Green goal of eliminating oil is accomplished. Stuff like plastics. All sorts of things depend upon plastics and plastics require petrochemicals. The most obvious one is plastic sterilization aids and sterile materials like syringes, packaging for needles, etc. ALL 20th century medicine is largely destroyed without petrochemicals. Also all pharmaceuticals deeply depend upon petrochemicals.

The respondent had no answer and she simply tried to resort to high-intensity angry BS. Clearly she'd never thought ANY of this through and didn't care because she was living off the anger of hating oil but knew nothing about how oil is used or how dependent all supply chains are on oil.

You are underestimating the good faith of the political class. In fact, they are borderline psychopathic with high levels Dunning-Kruger delusion about the correctness of their decisions/beliefs.

The additional issue: PVs have finite lifespan. Lithium batteries have extremely finite lifespans. So you have to replace them and have ALL the supply chains to do that forever. Which are fossil fuel dependent at fundamental chemical/physical levels. So most of those supply chains can NEVER be made green.

Green Energy is primarily a Cargo-Cult Religion not based on facts. That is a major problem because if you shutdown fossil fuels, we will end up with nothing - we will not even manage to have the levels of civilization and technology seen in the last 300-500 years. Basically a dark age.

One thing I've not seen a decent discussion of is what industries benefit from enormous amounts of almost free electricity? Other than the manufacturers of wind, solar, etc systems, how does this effect the economy? Obviously that effect is going to be significant, but what exactly does it look like?

it looks like most cities in the world -- excessive, 24-hour, advertising and safety with electricity.. the external costs of everything fossil-fuel are not at all inline with the reality of what is happening with Climate now

The quick answer is that we are not short of any of those materials. We might not be producing enough right now, but there's far more than enough that can be mined or recycled inexpensively. Increased prices will cause more mining and recycling, eventually the price will settle at the cost of production + something for profit. The something for profit is quite small, the coast for low risk capital is ~5% a year. Ther…

Right. Reserves are really just a measure of "things people bothered to look for at the current price." High prices can and do induce more searching. Part of the whole hullabaloo about "peak oil" is that people stopped looking for oil reserves in an environment with low oil prices. Once prices started rising you saw fracking come into play that regenerated areas previously thought dead for oil production.

That's not the argument of peak oil. It's not about price or quantity of oil available in the planet. It's an argument about thermodynamics.

The argument is that in order to extract oil, you need to spend energy, and, logically, the most easier oil to extract is extracted first.

That means that oil extraction is every year more expensive (energetically not financially). Because technology can make extraction more efficient but not indefinitely, at some point, in order to extract oil, it will be necessary to spend the same energy than burning it creates.

I suppose we could say that it's kind of an inversion of what's going on with fusion research.

Some commenters say that we already pass that point and that's the reason oil companies CaPex have fall in the last years.

I don't know if that's the case, but I can't avoid to ask myself about solar.

Is the energy that a solar panel generate in its life enough for its normal use, plus extracting the minerals that it's made of, plus push the panel, through the ocean all the way from China? or are we fooling ourselves using oil for all that?

I would like to see some numbers and expert discussion about that.

> we are not short of any of those materials For the most part you are correct. But building the mines, refining, supply chains, etc takes time. So you are perhaps missing one of the main points I was trying, maybe unsuccessfully, to make: we need to deal with the 'right now' and not just worry about how we'll be fine in 50 years. Lithium is a perfect example. We have plenty in the ground. We don't have plenty of min…

> We should be allocating Li carefully until those issues are resolved in 5-10 years.

Well intentioned policy like this can have the reverse effect.

If you limit lithium usage you will limit demand, which can reduce the effort expended to build new mines.

Complete BS. Green Energy has radically lower thermodynamic efficiency and energy density than ANY other currently used energy source (especially fossil and nuclear). These two qualities of an energy source have a direct relationship to economic efficiency and utility. Economics and Energy are 1:1 causal - economic growth ONLY occurs with energy growth. Lowering the quality of energy means lowering economic productiv…

No. Fossil fuels may be more energy dense But they need to be extracted, refined, transported and warehoused. The costs of greenhouse gas emissions through their environmental side effects are not even part of that calculation.

In the meantime, a wind turbine keeps generating energy as long a there is wind. We can't deplete wind or ocean waves as a resource.

The more we invest in renewable energy, the more efficient per follar speny it becomes.

That's not reality but a dream. So far we still have to find a sustainable lithium recycling on scale, there are various startups with various solutions, who actually prove to be just like most startup: PR scam for money or childish dream of someone who sold the cat before capturing it.

It's not better in mining estimation: we have estimations of different kind but they are nothing than dream, we do not really know how much lithium is accessible on earth.

You can buy stock in those companies and get your share of the profits.

On the one hand, the ability to usefully interact with the stock market is very limited for the majority of people, as they do not have the extra income to invest. It's very much a system in which the lower class do not get to meaningfully benefit from most the time. On the other hand, the companies will be made of people, expand by hiring new people, and pay these people with those profits, so much of the money will…

> Companies saving vast amounts of it in war chests is, IMO (depending on how they save it), as it's effectively removing it from the economy.

Nobody saves money in Scrooge McDuck cash vaults. All the money is invested, all of it. Even money in a checking account is invested. (The banks invest it, that's why they offer free checking accounts. They're not a charity.)

The majority of people do invest in the stock market.

> the lower class

is not the majority. Even so, brokers like Robinhood have made it easy for anyone with a phone to invest.

I downvoted because the first paragraph is dead wrong and needs correcting.

Carbon accounting for fossil fuels absolutely includes extraction, refinement, and transportation costs. Saying that it doesn't undermines everything else you say, because this is easily checked.
