The trump administration by refusing to admit the superior metrics of solar, they're just burying their heads in sand.

As admitting that solar is now a superior and cost effective means of energy means admitting that the US is no longer top dog.

As empires are built on mastering a source of energy.

the Portuguese | Dutch - mastered wind to power their ships.

the British mastered coal to power Industrial Revolution.

America mastered oil

now the Chinese have Solar.

even in places like Africa etc -- places were the grid was never available for $2k -- you can power your whole house with solar and lithium batteries. Panels are getting cheaper, same as batteries. Once the tipping point is reached for electric vehicles both personal and commercial - transition to fully electric mobility happens

I don't think I agree with this as it suggests they are doing it because they can't be bothered about it. Instead, they are doing it specifically because their (and/or their friend's) pockets are getting filled. To me, the latter is much more sinister.

You just slightly missed the crux of the issue here.

The big "problem" with renewables like solar is that once you've installed enough for yourself you are done for like 30 years. There is no monthly sun fee you need to keep paying. There is no solardollar, because there's nothing that needs to be extracted, transported, and sold every single day. A lot of billionaires are in an existential crisis over a world where fossil fuels are no longer the driving force of the economy. That's why we have incessant propaganda against renewable energy.

Even the solar panel market is self defeating. Once there is enough installed power the demand will drop off sharply as the refresh cycle is too long. The feedback loop of capitalism means we are likely to reach that point sooner than you would expect.

That said, don't think I'm like the nuclear power guys of the 50s who claimed that electricity would be so abundant that we wouldn't even bother to meter it. There are still costs with maintenance, repair, administration, debt servicing, and profits. If you look at your power bill today it will probably list generation, distribution, and taxes. Renewables only eliminate the generation costs, which are usually about half of the bill.

It's not going to happen soon - solar is still just 8% of world energy production. Even if solar will cover 100% of consumption on a sunny day it still would make sense to buy more panels to have enough output on a cloudy day or in the morning/evening. It's likely production of solar panels will be a good business till at least 2050 and oil business will start to decline before that unless will be propped by corrupt politicians.

An interesting prospect is the grids getting smaller. Becoming distributed again.

Why pay the enormous maintenance cost for a continental scale grid when you can in your neighborhood have a small local grid with solar, wind and storage followed by a tiny diesel/gas turbine ensuring reliability through firming.

When deemed necessary decarbonize the firming by running it on carbon neutral fuels.

More or less.

Adam Smith famously wrote that slavery was economically detrimental way back in 1776. It still took nearly 100 years to abolish slavery, and even to this day, people still equate slavery with prosperity (as implied by that controversial 1612 Project article, for example).

Another way to think about it, the South did not embrace slavery because it made them richer; the South embraced slavery because they opposed industrialization. Southerners would regularly complain about the hustle and bustle of the North, the size of the cities, and how hard regular (white) people had to work. The "Southern way of life" was a thing - a leisurely, agrarian society based on forced labor and land instead of capital.

In this regard it's a doubly fitting metaphor because much of the opposition to abolishing slavery was cultural and not economic.

Slavery had basically been a thing for all of human history up to that point, and based on my discussions on HN many smart people don't believe a lot of what Adam Smith said. There are still a lot of basic economic ideas that would make people much wealthier that struggle to get out into the wild. With that perspective the near-total abolition of slavery in a century seems pretty quick. And it can't really be a social thing because it is clear from history that societies tolerate slavery if it makes sense.

And we see what happened to the people who tried to maintain slavery over that century - they ended up poor then economically, socially and historically humiliated.

Slavery was already being abolished in the West when Adam Smith wrote the Wealth of Nations. But what was notable was that Adam Smith was really the first to make a strong case and prediction that it was not just the moral thing to do, but would lead to prosperity.

Adam Smith also differentiated between different levels of slavery - that Roman slavery was different than Serfdom was different from chattel slavery in the US.

It's worth noting that Adam Smith did not think total abolition was possible. One of his concerns about free markets was that people deeply desired control of other people, and slavery would increase as a byproduct of wealth.

And effectively it did: many people are kept in their place by the combined pressure points of debt and employment to stay (barely) afloat.

This is of course nothing compared to the cruelty of real slavery but the effect is much the same, a lot of people are working their asses of for an upper class that can ruin their lives at the drop of a hat. That there are no whips involved is nice but it also clearly delineated who was the exploiter and who were the exploited. That's a bit harder to see today.

Yes, they relied on the misery of others to drive their former wealth, but they are not the important people in that story. The important people are the ones that were no longer slaves.

And never mind that many of those former slave owners did just fine economically afterwards, after all, they already were fantastically wealthy so they just switched 'business models' and still made money hand over fist.

The full preamble of the Mississippi declaration is fascinating, and further shuts down doubters that the civil war wasn't about slavery and racism:

> Our position is thoroughly identified with the institution of slavery-- the greatest material interest of the world. Its labor supplies the product which constitutes by far the largest and most important portions of commerce of the earth. These products are peculiar to the climate verging on the tropical regions, and by an imperious law of nature, none but the black race can bear exposure to the tropical sun. These products have become necessities of the world, and a blow at slavery is a blow at commerce and civilization. That blow has been long aimed at the institution, and was at the point of reaching its consummation. There was no choice left us but submission to the mandates of abolition, or a dissolution of the Union, whose principles had been subverted to work out our ruin

Also, they clearly make the case that cotton was the most important good in the world, perhaps imploring the intercession of foreign powers.

I think it's worth pointing out though that these people were not being honest with themselves - nothing in their argument about the importance of cotton suggests it couldn't have been done with wage labor. They are dancing around the fact that only a very few benefit from slavery.

- The difference between Ben Franklin writing about farming in the 1770s and the civil war was that industrialization didn't hit the US until the 1810s/1820s when the first steel mills and steam engines were set up.

- "These people categorically did not want to start a farm; otherwise they would not have been facing famine." The vast majority of immigrants to the US at this time WERE farmers who were not allowed to own land in Europe. The reason they came to the North instead of the South is because they were largely not allowed to settle anywhere East of the Appalachians in the South. The South was staunchly anti-immigrant and barely had any cities at the time.

- At the outbreak of war, the Union army was almost entirely made up of American born volunteers. Later, immigrant brigades were enlisted, but most were highly regarded and commended and still made up less than half of the army.

Maybe - a lot of the material wealth of the South was having a lot of land divided amongst fewer people. Enjoying more leisure has a nasty habit of not making people richer in the end.

Here's specifically what Adam Smith had to say in the Wealth of Nations:

> But if great improvements are seldom to be expected from great proprietors, they are least of all to be expected when they employ slaves for their workmen. The experience of all ages and nations, I believe, demonstrates that the work done by slaves, though it appears to cost only their maintenance, is in the end the dearest of any. A person who can acquire no property, can have no other interest but to eat as much, and to labour as little as possible. Whatever work he does beyond what is sufficient to purchase his own maintenance can be squeezed out of him by violence only, and not by any interest of his own.

Later, to explain this trap of why people insist on owning slaves even if paying workers would be more productive in the long run:

> "The pride of man makes him love to domineer, and nothing mortifies him so much as to be obliged to condescend to persuade his inferiors. Wherever the law allows it, and the nature of the work can afford it, therefore, he will generally prefer the service of slaves to that of freemen."

Human slavery might be one of the few exceptions to this. People can reproduce and create more people provided they are given the bare necessities of life. As long as you could keep the enslaved under control, you would have new slaves you could constantly sell and they mostly took care of themselves.

Honestly it sounds like a great life for an unambitious, lazy person. Maybe we’ll all be able to experience something similar when humanoid robots are commonplace in the future. Find an isolated piece of land with a few robots. Make them grow food and commercial crops. Raise some animals. Live a life of relative self sufficiency and leisure.

The issue (for the masters, and besides any ethical issues) is being a slave master is a very tenuous position, and prone to revolts.

Too capable (but also valuable!) slaves tend to be self sufficient and strong enough to throw you off.

Too weak (and therefore non-valuable!) slaves tend to be easy to control - but are a huge drain on the system, including ‘master’ management, which is often the most constrained resource anyway in any hierarchical system.

Prior to the steam engine, what sources of energy you have?

The wind and the water, both rather limited to specific activities (milling, sailing). And the power of human and animal muscle. Where the animals are stronger, but also much dumber, so most of the actual hard work has to be done by human hands.

Basically all the settled civilizations used some sort of non-free or at best semi-free labour. Villeiny, serfdom, prisoners of war, slavery of all sorts, or having low castes do the worst work.

And given that humans are very good at rationalizing away their conditions, the cultures adapted to being comfortable with it, even considering the societal inequality as something ordained by the gods or karma.

"Oxen? Paid laborers? "

In other words, animal and human muscle, we agree on that.

I didn't claim that all human labour was non-free, far from that. Every classical civilization had paid artisans and employees as well.

But the paid professions tended to be the skilled ones, and the non-free ones tended to be the arduous, backbreaking ones.

"The South was notable in clinging to slavery long after it had been abolished elsewhere."

https://en.wikipedia.org/wiki/Timeline_of_abolition_of_slave...

They were about as delayed as Russia. (Serfdom in Russia was not quite slavery, but brutal and backward nonetheless.)

And the timeline of slavery abolition seems to dovetail with the expansion of the Industrial Revolution across the globe quite tightly, or not?

"it was at least in part cultural."

There were plenty of non-slave manual laborers throughout history. Doubly so for chattel slavery of the sort practiced in the South.

What we'd now call the developed world.

That article lists many restrictions and abolitions of the practices hundreds of years prior to the 1860s. The Russians you mention managed it in 1723; Massachusets deems it unconstitional in 1783. By the 1860s still having it as a properous nation was pretty weird.

"What we'd now call the developed world."

The developed world of now is much more extensive than the developed world of the 1860s, and the South was very backward until the 1950s or so. In the 1850s, it was seriously lagging behind the North in industrial power, which is one of the reasons why they lost the war. This would point to a yet another chicken-and-egg problem. Nonfree labour tends to cement premodern societal and economic structures, which perpetuate existence of non-free labour, unless disrupted from the outside. The Islamic world didn't give up slavery voluntarily either.

I am not sure if we can call the South of the 1860s "developed", even relatively to the rest of the Western civ. By what criteria?

"The Russians you mention managed it in 1723"

Serfdom in Russia was abolished after the Crimean War, and the Tsar used the money gained by the Alaska Purchase to pay off part of the due compensations to the nobles.

Yes, these institutions were not equal. Different cultural and historical development. Still, a Russian serf of the 1850s was a very non-free person, tied to the land and dependent on whims of his lord or lady. Few would care if a drunk noble whipped him to death, even though theoretically he should not be doing that. A rough equivalent in category.

That doesn't tell the whole story though. If you own 100 slaves, you need to spend nonzero resources maintaining them, or else they will starve and then you have zero slaves. So the owner has less wealth than the equivalent person in the North that has the same income but zero slaves. You can't directly compare GDP per capita excluding enslaved people.

It's a cute ideal, but you can't disentangle government from the energy sector. It's too big.

How do markets build infrastructure as large as an LNG terminal without the government tipping the scales with various guarantees? How do you build a literal coastline of refineries without government clearing the way with permissive regulations? How can you say "let markets figure it out" when the US military is the acquisition department of Halliburton's Iraqi joint venture?

Pretending "markets can figure it out if we just remove government subsidies" is hopelessly naiive. Geopolitics is mostly energy policy.

> belief that slavery was really ended by industrialization making abolition economically advantageous

On the contrary, historians broadly agree that industrialization (particularly the advent of the cotton gin) actually turbocharged the human trafficking industry in the US. The cotton gin moved the bottleneck for textile production onto enslaved people, since there was no automation available for planting, cultivating, or harvesting the cotton.

Re: slavery: I've wondered before if the arrow of causation might go both ways. Slavery has existed throughout history. With slaves, what's the incentive to industrialize? You have "free" and captive human labor. But take that away, and suddenly the idea of machines doing stuff for you seems a lot more compelling.

Slavery also displaces industry in the economy. Slave-driven industries compete with industrial development for investment funds and production driven by slave labor can compete with mechanized production. But if labor is suddenly expensive, mechanized production has an advantage, and if former slaves are now getting paid there are also more customers for the output of that production.

So industrialization may have played some role in abolition, but did abolition also drive industrialization? Slavery was abolished in Britain in the early 19th century and Britain was also the cradle of the industrial revolution, which started to hit very shortly after. America did not explode industrially until after it abolished slavery.

If we'd abolished slavery in Roman times we might have terraformed Mars by now.

There was even an economic incentive for this because lighter skinned slaves were more desirable for domestic labor. By the 19th century this had gotten so absurd that some slaves were almost indistinguishable from white people due to generations of repeated rape, basically.

There was a book whose name escapes me that analyzed the records of one of the largest slave markets and it found that the price of girl slaves went way once they started menstruating. This was advertised. Why do you think that was?

I really don't understand why you're bringing slavery in a discussion about hydro. Why not bring Gaza? And Iran? This is a tech site after all: so, sure, bringing slavery in a talk about solar energy makes sense.

Note that the abolition of slavery is unrelated to industrialization: the islamic republic of Mauritania was the last country to officially abolish slavery and they did it in the 1980s. And it's very well known that slavery still persisted long after that and there are still people owning slaves today (not too sure why the other comment mentioning it was downvoted).

At this point I think people are just insane: they'll use any excuse, on any unrelated subject, to bring it the issues of slavery, patriarchy, Gaza (but not Iran), etc. But as soon as you point out actual patriarchal societies operating today or actual slavery still happening today or people having actual sex slaves in western countries (e.g. several members of the UK parliament are now running an enquiry into a gigantic gang-rapes operation with thousands of victims and an attempted cover-up by the authorities and the findings are beyond belief).

That would be around 30kwh per day so probably not, but you could get close.

Assuming you're in the US, new solar modules go for about $0.28/watt.

If you dump the entire $1k into just modules, that will get you about 3.5kW of panels. Which will probably hit your target on sunny days during the summer.

But that doesn't include inverters if you want to do a grid tie, or batteries if you don't, or wiring, or whatever you're going to mount the panels on.

$1,000 is definitely too ambitious for that much energy. Even just the charging plug for the car is going to take a sizeable bite out of that.

Another way to think about this is that $1,000 is about 20 tanks of gas, assuming you get 400 miles per tank that's 8,000 miles, which is less than a year of driving for the average American. You can increase your budget and still come out way ahead.

The other consideration is that this scheme only works if you only drive at night, otherwise you'll need a battery to store that power while your car is out and about during the day, or you'll need to grid tie and use the grid as your battery.

then get a frame for your solar (or build a barn and roof it with solar, its cheaper than 12mm plywood at the moment.)

Have micro inverters, they are more expensive, but solid state, less likely to catch fire, do MPPT better, and are not a single point of failure.

You'll need backup for when solar doesn't cover your daily needs, so either grid or some other power source.

You will likely find that the least terrible way to do what you're asking is to build some sort of minimal cabin or something to get the whole project to be residential. Even then you will likely have to dial back your clearing a lot and structure the project in multiple phases over many years to not incur non-starter level costs.

You're gonna learn more about the clean water act than you ever wanted to know.
