Not totally surprising. The way I've seen it working is people trade around where the price was yesterday and it goes up and down a bit. Then every so often - when not enough coal is being produced - the buffers at the mines and ports run out and the situation becomes a straight auction for the last scraps. That usually makes the price graph draw a ski-jump shape.

It is a pretty good time to be a coal mine. A lot of investment has been scared out of the sector, so not so much competition. But people still keep using coal.

Even though they really, really shouldn't. As you undoubtedly know, it's a terribly dirty fuel source that is destroying the planet. When I saw this headline, my gut reaction was actually "good -- I hope that makes other fuel sources more competitive". I then realised that I am not an economist, and that it would have the opposite effect -- increasing production.

One thing I'd love to see come out of COP26 is an internationally agreed minimum tariff per ton of CO2e, including electricity weighted by its means of production. We want coal to be very expensive to buy (and very cheap to sell).

Not a economist either, but those are not exclusive.

Also, this is not the case here, but ever lowering demands triggers structural prices increase at some point, due do scale cost reduction not working anymore, but you won't see investments in production either.

Welcome to the reality. People don't want to freeze in their houses. People will gladly listen to the talks how renewable energy sources are good for our planet, they will even go on "climate strike" marches... until temperature drops at home below 21 degrees.
A lot of people are also willing to invest in better isolation and sustainable ways of heating their homes.

Meaningful action does not require us freezing in our houses, not yet.

But you have a point, which is exactly why survival of our societies should not be a choice on the consumerist menu. The government, the justice system, the corporate world and finally the citizen should lead in the struggle to decarbonize the world, not the consumer.

> The government, the justice system, the corporate world and finally the citizen should lead in the struggle to decarbonize the world, not the consumer.

That always sounds like an excuse for doing nothing to me.

It's better than that, it's an excuse for doing nothing and blaming the other for nothing getting done.
No. It's the other way around: shifting responsibility from government and corporation to the individual is an excuse for doing nothing and blaming you for nothing getting done. This is how recycling and the carbon footprint is invented - by the softdrink and fossil fuel industry. You have just fallen perfectly into their traps.

Just listen to the rhetoric that Shell uses: this is literally what they say.

It's the reverse: it's pushing this responsibility to individual consumers that's the scam here. This shifts the blame to actors that cannot really do anything meaningful about the problem, and as a result diffuses it so that people who can do something don't have to.
You need pioneers, people who show it is possible to live a good life without destroying the planet. You won't ever convince the majority to change their ways without it.

Blaming the big bad corporations whilst we continue to consume their crap is a cop out. We've been doing that for decades now and nothing much has changed.

> You need pioneers, people who show it is possible to live a good life without destroying the planet.

The thing is, it isn't. People aren't islands. Our societies, our economies, are structured in a way that make it really hard to keep your impact on the environment low. It's hard to give up on a car in a car-oriented town or country. It's hard to give up on plastic where every single thing you buy has some in it. It's hard to give up on meat when it's the most cost-effective form of nutrition you have available. And then, when you add up all those sacrifices - the result is not living a good life. It's mortification on principle. It's not something you can reasonably expect everyone to follow.

(At a risk of bringing religion into the topic - Jesus has said, "If you want to be complete, go and sell your possessions and give to the poor, and you will have treasure in heaven; and come, follow Me."[0], and yet almost no Christian in history ever actually did that. No, these words are used as comfort for those already poor - an explanation, not a plan for life. Environmental self-sacrifice, which doesn't have a mainstream belief system backing it, can hardly be expected to fare better.)

Add to that, most people have no fucking clue what is or isn't destroying the planet. Hell, I consider myself somewhat broadly educated, striving for evidence-based, rational thinking, and I still admit I only have vague idea. There are some obvious things one can do, like "don't fly if you can avoid it", "don't use a car[1] if you can avoid it". Then there are plenty of wrong ideas, like "always unplug your chargers" (negligible gain for significant "I've made an effort" cost) or "use reusable bags instead of single-use plastic ones" (actually plastic bags come way ahead environmentally). Most other changes popular articles list tend to be hard to evaluate - they may or may not help, depending on various second-order effects and proper accounting of impact across product/behavior lifetime, which is often nearly impossible to do.

And all of that - all of that - relies on almost everyone making those same sacrifices simultaneously[2], so the effect is noticeable, all while people not making the sacrifice are visibly better off[3]. Meanwhile, corporations and governments are the ones making the most impact[4], and importantly, they hold the biggest levers. A single law, or a single contract change, can make much more impact than thousands or millions of people abandoning everything and moving to live in the woods as hunter-gatherers.

The way I see it, trying to convince everyone to make personal sacrifices is a fool's errand, and insisting on this as a solution is sabotaging our future. This is a systemic problem, we need systemic solutions.

Yet my grandparents led a low impact lifestyle without even thinking about it.

This is more of the same. Excuses.

What one must do as a citizen is put pressure on the government.

And, as a consumer, one should also make climate friendly choices, but it's not the most important thing and it should not distract us from where the real difference is made.

I never understand this point of view.

We decide what happens, collectively. We vote in governments, and we choose what products to buy. It needs to start with citizens because we're democratic.

The problem is that people's public speech doesn't match their behaviour. Carbon offsets for flights have been available for years. Despite ~75% of people saying "Climate Change is the biggest threat we face" [0] only 1-3% of passengers actually choose the carbon offset [1].

In startups, we know that people lie in surveys, and we need to measure their actual behaviour in order to correctly assess their actual feelings/intentions. From this, we can conclude that most people profess a public belief in climate change, but privately don't care and aren't willing to do anything about it. Companies are taking their cue from this: virtue-signal about changing the world, but don't actually do anything. Governments are likewise taking their cue from it: lots of conferences, lots of talk, no action.

We need citizens to stop driving in petrol-driven cars to marches where they protest about carbon emissions. To stop heating their homes with coal. To stop eating fish completely. To buy the carbon offsets, even if they're crap and not very effective. The mismatch between our public speech and our private behaviour is what's causing everyone else to do the same. It has to start with us, because if it doesn't it'll be ignored.

This attitude of "someone else has to take the first step" is what's causing our inaction. Stop blaming others for your footprint, and do something about it yourself.

The whole point of organized anything is to have common laws for everyone. That's why there exist laws regarding waste, otherwise some people would just dump them to random places. Or why do we have referees in sports? Because the teams have agreed together that it's the best way to enforce the rules for all of them.

Pushing "just personal action" for climate issues is a known delay tactic.

No, shifting blame and asking for individual action is a well-known tactic from the corporate propaganda playbook. Consumers have neither the necessary information, nor the necessary time to individually weigh all the different factors they care about whenever they purchase something. Very few problems are solved by demanding individual action. Leaded gasoline wasn't phased out because people started driving to boutique fuel stations that offered unleaded. Acid rain wasn't stopped because people started buying power from boutique power plants that installed sulfur filters. Our problems with the ozone hole weren't fixed because people chose not to use refrigerators.

These problems are why we invented governments and central regulation. At the very least we need to internalize the cost of pollution.

I definitely disagree.

What I don't understand, when I assume good faith, is why people disregard calls for political action as lazy or waiting for "someone else to take the first step"; while also have certain actors pouring millions on lobbying and campaigns to downplay the effects of global warming, to understate the viability of green energies and lastly, on pushing the idea of consumer responsibility.

Excellent reasoning, but I strongly disagree with the conclusion. The gap between action and belief is exactly why we need collective action, not individual action.

There's a difference between us as a citizen, and as a consumer. The pandemic has shown perfectly that leaving everything up to 'individual freedom' will result in a mess.

> Stop blaming others for your footprint

Did you know the very idea of a footprint is invented by BP as a mechanism to shift responsibility and place blame on the consumer?

Personally I spend a large part of my income on reducing my footprint by the way, but I have no illusions that this is where the required change will come from. In the country where I live, merely being registered as a citizen, paying taxes and everything that is legally required, will have am unsustainable footprint - before I even begin to take a breath I have consumed my share.

What we need to do is hold the actors who are responsible accountable and make a mass collective change that is non-optional.

In the reality I live in, there are alternatives to coal that are just as capable at heating your house but produce much less CO2.
They aren’t as cost effective, powerful, or as widely deployed.
Coal isn't cost effective if you price in the full costs of using it. As long as someone else will pay them for you, yes, it's very cost effective.
That's exactly the point of creating a CO2e tax : making cleaner energies more cost effective by subsidizing them.

Renewable energies are cheap (they are basically "free"). Deploying them is expensive. But you only have to subsidize the cost of deployment and after that it's cheaper for everyone.

It's the same thing with insulation : it's expensive, but once it's done correctly, you can basically heat your entire house with only the sun (if it's there) or really low energy consumption.

We're just missing the political will. The transition is possible and would create jobs for the decades to come.

> Renewable energies are cheap (they are basically "free"). Deploying them is expensive.

That just sounds like a half-truth, otherwise people wouldn't always be so impassioned about subsidising renewable. They'd jest buy land and build honking great renewable plants.

Now the situation may have changed in the last decade or so, because the growth in renewables is very real. But it takes no political will to deploy cheap energy. There would be queues of bankers trying to invest if they thought they could undercut market producers and make good returns. Every greedy person on the planet (so somewhere in the region of 8 billion of them) would be happy to get in on the deal.

You can't just buy land and build wind turbines and solar panels. You need expensive permits and then spend a couple of years in court battling various citizen groups who don't like renewables anywhere near their homes. You can't even put solar panels on the roof of an apartment building and then sell the power to the tenants, regulation prevents it.
Coal mines and power plants face the same challenges. They manage, somehow.
They manage mostly by being older than these regulations.
They manage because politics pushes these things through while creating new regulations for renewables.

E.g. in Germany one of the chancellor candidates was state MP and personally & illegally forced expansion of coal strip mining while enacting new rules making wind power essentially impossible in his state.

> You can't even put solar panels on the roof of an apartment building and then sell the power to the tenants, regulation prevents it.

At least in my country, AFAIK regulation explicitly allows for something like that: there's a net metering modality in which a group of consumers (for instance, a condominium) can split the credits from the net metering of a shared solar power plant. It's meant for precisely that scenario (power panels on the roof of an apartment building, each apartment has its own independent meter).

Awesome. I hope Germany fixes the legislation around solar too.
I don't think that heating with coal is a thing anymore. Power production is, though and that goes into electric cars or cooling buildings. Heating with electricity can be done quite efficiently via heat exchangers but is not used that often besides relatively new single-family homes.
Depends on where you live. Poland is burning more coal than it was in the 90s, and a significant amount of that is still for home heating
The world as a whole is burning more coal in 2020 than in 1990 (and 2020 was a big downyear because of covid).

But what's more surprising is that even in per-capita terms, global coal usage has increased since 1990.

However if you change your baseline year from 1990 to 2012, then global coal usage in absolute terms has declined, and will continue to decline over the long term even if there is a bump from the 2020 depressed levels (2020 is a terrible year to benchmark against).

Coal isn't just for electricity, it usually rises and falls with the price of steel because it's needed for the process. Also has use in a bunch of other things like water filters.
I thought water filters use charcoal, not coal.
It's going to have both effects simultaneously. Production is not going to increase very much overnight, because coal mines are not particularly elastic. However, most coal consumers are actually in the market for electricity, so high coal prices will encourage substitution with alternatives like solar.
High electricity prices also eliminate the cost of (some) subsidy schemes for sustainable energy. Which almost can't help but encourage more such schemes.

The UK's CfDs (Contracts for Difference) pay schemes like wind farms a fixed price for their output, allowing projects to go out to market saying look based on our plans we're going to make so-and-so-many MWh of electricity, the UK promises to pay so-and-so-much £££ for that electricity, therefore lend us (much less) £££ to build it and we'll pay you a nice return. This means investors only need to care about whether your wind farm proposal actually makes electricity, not guess what the price of that electricity will be when it's sold.

Normally these schemes cost the government money. Say electricity is selling for £50 per MWh, and your wind farm's CfD specifies £80 per MWh, the government hands over £30 per MWh extra to make up the difference.

But, when prices sky rocket the government actually gets paid the difference. When electricity sells for £200 per MWh and your wind farm's CfD said £80 per MWh, you only get £80 per MWh as promised, the other £120 per MWh goes into the general fund to buy missiles or feed orphans or whatever.

Part of the problem in the UK is that the amount of wind was at something like a 40-year low earlier this year, meaning that wind farms weren't producing that much at all. As the amount of renewable power increases and fossil fuels get phased out and become more expensive, we can expect high electricity prices to coincide more and more with times when renewables are producing very little power and low prices with times when they're producing lots of it. So even if CfD prices look good on paper compared to average electricity wholesale prices the government is still likely to lose a lot of money on the deal due to when that electricity is produced, which ultimately comes out of all our electricity bills.
How do you even heat a house with wind? Aren't most homes in the US and EU are heated with gas?
If a home has a heat pump (most AC systems), heating primarily with electricity isn’t that hard, at least in milder cold temperatures.

Most homes in the colder areas of the US heat with gas because the cost per joule of gas is a lot less than for the equivalent electricity. But a lot of homes can supply most their heat with electricity, and would if the economics made sense. And even more would build that capability if gas was 2x the cost per joule as electricity.

Also even ignoring the direct price of the fuel, unlike for most things for heating it makes practical sense to burn gas in your house to make it hotter, not burn gas in a power station, then ship the power to your house and use that to make it hotter.

A modern home boiler is very efficient, because what you wanted was heat, which is exactly what you get by burning gas. The gas turbine at a power station has to do the same conversion (burn gas to make heat) but then also convert the heat into electricity, and that's before transport loss.

In the ideal world, the choice is between "Burn gas in your home" (bad, accelerates climate change) and "Use renewable electricity" (good, although maybe expensive depending on policy decisions). But for many people today there is no choice, resistive electrical heating would still burn gas in a power station and just cost them a lot more.

Heat pumps tilt the scales, if they're practical for you, it really is possible that a heat pump running on electricity that's actually produced by burning gas works out cheaper and more environmentally friendly than just burning the gas yourself. And of course a heat pump powered by wind is entirely practical and potentially quite cheap.

> A modern home boiler is very efficient,

A gas-driven heat pump could be even more efficient; that is, it could deliver > 100% of the thermal energy content of the fuel to your home (in the form of low grade heat). This is a consequence of avoiding, at least partially, the large second law loss in a typical furnace where very hot flame transfers heat to rather cool air. Any time you see a large entropy generating process like that in a system it's an opportunity for improvement.

But for example this week electricity prices are very high, and yet it's somewhat windy. Something like 4GW plus or minus of wind power over the weekend. Not enough that the high price of gas doesn't dictate the market price of electricity, but enough that a clawback of £100 per MWh (not at all unlikely with current prices) would be something like £20M to the exchequer.

> we can expect high electricity prices to coincide more and more with times when renewables are producing very little power and low prices with times when they're producing lots of it.

Yes to some extent that's true, and we should expect demand management to play a big role in reducing the impact on ordinary households. Alec Watson (Technology Connections) did a video about how his home is set (in summer) to cool over night when power is cheap, so he wakes up in a cold but not yet uncomfortably so house, and during the day the cooling is off, so it gets warmer but unless the day is especially miserable it still isn't actually hot inside until the evening, at which point electricity is cheaper again and it begins cooling back down. This way he gets air-conditioning, in a climate where it's not entirely essential but certainly desirable, yet doesn't pay peak prices for it like his neighbours. Imagine if more people did that!

The UK could use a lot more storage. What it has is mostly black start capacity re-purposed as normal storage, but it is a bit short on non-picturesque mountains to modify. It also, of course, decided it didn't want to be part of the EU, where there's an entire continent of renewable energy sources to trade with, several hours difference in dawn time and considerable variation in weather - the UK is still connected to their grid with several Gigawatts of ties but now trades as an outsider.

>It is a pretty good time to be a coal mine.

Not in EU where Germany decided we should all use Russian gas from pipeline bypassing other EU states.

https://edition.cnn.com/2021/09/20/europe/poland-coal-mine-t...

According to the linked chart, that mine should be making on or about $(240-100)=$140/t in profit - since they were breaking even at $100 and now the price is $240.

That $600k/day fine is therefore about 4,000 tonnes of coal (ie, nothing). The mine produces ~ 76,000 tonnes a day. That is what the free market thinks of the EU's fine.

The situation isn't that simple since the export price is for black coal and the Polish mine would be producing lignite, but ski jump prices are no joke.

Article unclear: Thermal coal or coking coal? If this is for all coal, I would expect the price to go up as demand for thermal coal decreases (as coking coal is higher quality and therefore costs more). Although some cursory googling indicates that the prices of both have recently increased.
Piece rise was mostly to metallurgical coal, over the last year. However the 25% spike in natural gas prices in Europe in the last month, are now affecting thermal coal prices.
it will go down again soon. these things happen. it cant keep going up, capitalism will fix it.
This is not just a coal story. Natural gas prices started rising a few months earlier, which put upward pressure on other energy commodities like coal and oil.

https://tradingeconomics.com/commodity/natural-gas

Divesting of oil, coal, and natural gas is premature. We can't meet our needs with clean energy alone. Fossil fuels will still be needed for many years to come.

China needs more coal, Europe needs more natural gas. Winter is coming.

This will stay true until we start divesting from fossil fuels and investing in clean energy.
Some here appear to disagree, as if fossil fuels are taboo now. You can't say no to nuclear and fossil fuels, that's just reality for the next few decades. After mid 2030's I can see coal dying and oil dwindling like coal is now. Even if somehow everyone adopted electric cars in the next 10 years fully that still leaves giant ships, planes, trucks and so much more applications that are simply uneconomical to displace within a short time even if the replacement's value is the old use's current market value.

Fossil getting expensive long term means all those natural gas sites that covid shattered could now reopen because it is becoming profitable to take them out of ground. This benefits oil companies, but it also creates an opportunity for alternative energy conversion. Why heat houses in winter using expensive/price-unstable natural gas when solar and wind exist, except saying no to nuclear meant it can't even be used as a backup to solar/wind which they need for obvious reasons. Unless of course there is a new revolution in battery tech I don't know about

I'd say some don't like to hear the truth. But I get it. It's painful and unpleasant to hear especially when it comes to having any sort of empathy for the demise of fossil fuels and all of the related industries.

In addition to all the fossil fuel vehicles that you mentioned, you have also consider all of the industries and livelihoods as well (I'm sure you meant this implicitly). Those who work in oil-fields/sea-platforms, ICE factories, refinement equipment, and so on... If such a transition could happen over night, it would be devastating to so many industries, individuals... even entire economies and countries.

While it's difficult to have any sympathy for the incumbent/legacy/ICE car manufactures being "unable to compete" with Tesla and new wave of Chinese EV manufactures, it can't be easy for any of them to transition without significant pain. Esp with all of the incentives, laws, etc... that have set up over the last century. You have billions of dollars of oil subsidies, franchise laws, worker unions, and so on.

This where the government needs to step in. Fossil fuel subsidies need to be phased out. Training citizens with the knowledge and experience to work in these new industries needs to be provided. New incentives for manufactures to transition to sustainable methods of transportation need to be created. Old one eliminated.

Ties to and influence of lobbies associated to legacy industries and fossil fuels need to be dismantled, even if the only way to go about that is through the creation of new, more powerful and influential lobbies that represent clean and progressive alternatives. I have my doubts that Tesla would be what it is today if they had played by the book, no matter how superior their technology is.

Clean tech can't fill the void left by fossil fuels? Start promoting and evangelizing the advantages of nuclear options.

I guess my point is it's going to be painful no matter how much people fetishize clean tech. Everyone is going to suffer in one way or another, but it has to happen and it needs to start now. I know that there are things being done about it already, but it's not enough.

> Fossil fuel subsidies need to be phased out.

Fossil fuel subsidies are a social stability measure. There are going to be hard times when people can't afford fuel to heat their homes in winter, and have to endure lectures by the private-jet-to-next-climate-conference-crowd on how morally flawed they are for still affording to light up a candle at night.

There’s a pretty simple solution there: move the fossil fuel subsidies to subsidize people directly. For instance by paying the first $N of their fuel bills (where N is determined based on something like the expected required energy for the month). This way people in smaller-than-average and more energy efficient homes don’t get slammed by high prices, but they can still save even more by reducing their energy needs.
Frankly, I wonder if we will ever be completely free from fossil fuels. Renewables have a few problems that need solving.

What do you do when the sun isn't shining and the wind isn't blowing?

Storage would fix that except we don't have a storage solution that scales to the levels we need and is widely implementable yet.

What do you do if the sun decides not to shine and the wind decides not to blow for a long time? What do you do when you exhaust your energy stores?

The only thing I can think of is restarting the natural gas and coal plants. Fossil fuel plants will have to be maintained (and staffed) as a backup. Nuclear will work too I guess but same problem, maintenance and staff.

The only scenario I can see where we rely totally on renewables only is when we have a huge excess of renewable energy generation and a lot of extra energy storage such that it will buy us enough time to look for alternatives if the weather decides to go weird and deny us solar and wind power.

Power2Gas scales, it's just a bit expensive right now.
The solution to those things is long-range transmission capability and an adaptive grid. The wind is always blowing somewhere, the sun is always shining somewhere, and at least one of those somewheres will have excess in a properly built out grid.

None of that is beyond our capability, the issue is getting the will and dollars to build it. The way it's currently going we're organically building small clumps here and there where capital is available with no overall direction. That can work in the long run, but it means the build-up period will be marked with unequal outcomes by region and gluts/shortages.

Where the sun is shining/wind is blowing might be too far away. There are limits to how far we can draw power from technically, economically, and politically.

Also other regions need power too so you would be straining their supply - unless you have, again, huge excess in generation capacity.

The cost of a simple cycle gas turbine power plant is maybe 4% of the cost of a new nuclear power plant (and combined cycle just 10%), so backing up the entire grid with turbine capacity isn't that expensive. You need fuel for those turbines, but that's where hydrogen comes in.
To clarify: I meant cost per unit of rated power output.
I completley agree. Being able to designate remote arid locations for power generation and being able to transmit that power elsewhere will have a huge impact on society and the environment.

My crazy idea is high power lasers and satellites reflecting the sun (magnified beam/laser for minimal night sky disruption??) to the other side of the planet. I wish I had the right education to come up with good ideas, if it was up to me there would be arrays of satellites that convert the sun's light to laser or just a focused beam and literally boil the ocean to generate power! (Good thing there are smarter people working in these problems)

> What do you do if the sun decides not to shine and the wind decides not to blow for a long time?

I always see this argument in these kinds of discussion, but does anyone have real statistics as to how often that actually happens? And how widespread these disruptions actually are, keeping in mind that solar and wind power are often distributed over a wide area?

(Keep also in mind that, unless there's a solar eclipse, photovoltaic panels can still produce some power even when it's very cloudy, so that might not lead to a total loss of generation.)

If you need a grid that has, say, three 9s of reliability (US grid) or four 9s reliability (European grid), then it can only happen for like 15 minutes per year in Europe or 150 min per year in the US.

Now if you are only using wind for 10% of your power needs, a 10% drop in wind is not a big deal. But when you are using wind for 30% of your power needs, then the same variability becomes a bigger deal and might start to impact reliability, even though the wind itself is not more variable than before. Same for solar.

Well just last month …

https://www.wsj.com/articles/energy-prices-in-europe-hit-rec...

Renewables like solar and wind depend on the weather - which we cannot control at all. Non-renewables have dependencies too like politics and economics but at least it’s something we have some control over.

If solar and wind is to completely replace non-renewables, their intermittency is going to have to be dealt with somehow - and huge excess in generation and storage capacity is only way that comes to mind at the moment.

You can play with designing a renewable + storage system to supply "synthetic baseload" using actual historical weather data at this website:

https://model.energy/

(The handling of transmission is greatly simplified, but that's ok for what that is.)

> Frankly, I wonder if we will ever be completely free from fossil fuels.

One way or the other, this is inevitable. There's only so much fossil fuel that can be burned before the environment becomes too hostile for civilization to survive.

> What do you do if the sun decides not to shine and the wind decides not to blow for a long time? What do you do when you exhaust your energy stores?

Power2Gas gets you to 100% at a reasonable cost. Batteries act as short term storage, with most of the stored energy going through them; the gas provides long term storage and back up generation, with most of the energy storage capacity there (with a much longer average residence time). There may also be room for intermediate storage on the timescale of a week or so (pumped hydro, thermal, for example).

Multiple levels of storage like this is analogous to the cache hierarchy of a computer, in that combining different storage technologies with different properties can provide a solution that is better than any of those just by itself.

Even setting aside the environment, there is only so much oil and natural gas. IIRC, there is only enough to last through this century.
One solution: build enough nuclear to cover your nighttime load and run that 24/7, add enough solar to cover just the extra load during the day, and for remaining discrepancies with demand use either batteries or load-following by the nuclear plants, whichever is cheaper.

A while back MIT had an electric grid cost simulator online, and that was the cheapest fossil-free combination I could find.

Did the simulator include hydrogen? In many places, hydrogen reduces the cost of a 100% renewable grid, vs. just using batteries for storage.
Don't remember. Is anyone doing that in production? If so, what does it cost?
There is some underground hydrogen storage (used to smooth output to ammonia synthesis, for example), and some hydrogen pipelines (about 1000 miles in the US), and combustion turbines have been available for 30 or more years that will burn hydrogen. So all the parts are available. Electrolyzers need to be sufficiently cheap to work well with intermittent renewables, but their cost is dropping rapidly.

Integrating preexisting technologies is the easiest and surest kind of innovation, even if they haven't all been brought together yet.

There are cost estimates at the reference link at https://model.energy/ , along with projections of future costs.

> We can't meet our needs with clean energy alone.

Nuclear energy does that just fine - as a result, France is the lowest-carbon major nation.

The jury is still out. We have not gone through a handful of construction/decommission cycles of nuclear power plants, simply because the lifetime of a nuclear power plant is over half a century or more, and France started its nuclear push as late as the '70s.
The U.S. has had stagnant energy production since 2008

https://www.eia.gov/energyexplained/electricity/electricity-...

The U.S. generates about as much energy from renewables as it does from nuclear. Combined (nuclear + renewables) only produces around 40% of the energy the U.S. consumes.

In 2008, the combined nuclear + renewable energy accounted for 29% of the energy consumed by the U.S. (green energy production is only up 100% in 10 years). Mostly there was just a swap from Coal power to Natural gas power.

Put another way, it'll be decades with no energy growth to replace the natural gas and coal energy production; baring some massive changes.

At the end of the day, renewables are not going to cut it. We need a massive increase in nuclear, it's the only clear way. If the goal is to switch off coal and natural gas (which IMO, we should just keep using coal + natural gas). Cheaper energy, is the quickest way to reduce poverty.

This argument is incoherent. Renewables did not force out existing fossil capacity on their own, so they are inferior to a nuclear plan where we do force out fossil capacity? Why not build renewables and also force out that fossil capacity?
The gas hike is mostly the outcome of Putin's squeeze onto Western Europe to adopt NS2 on his terms.
Who would of thought? Didn't some US Administration hint at this, that Russia would leverage the pipe to fuck Europe? Unfortunately the current US Administration actually gave Putin the green light to fuck the Euro poors, sad.....

Clown world....

I can think of 2 instances where Trump publicly questioned EU members' reliance on Russian energy. Once when he visited Poland and then later at a G7 summit.
Yeah, that was what I was referring to. Trump was correct, Russia will fuck the Euro Poors like it is doing now.

Biden who has dementia has no plan and basically gave Putin the green light.

Many companies have confirmed that Gazprom actually adheres to the existing contracts and prices. Gazprom is not, however, offering short-term sales at the currently negotiated long-term prices; in other words, Gazprom is not selling gas over the counter at 1/5 the market rate.

This seems to me like one of these opportunities where some EU gov'ts are blaming Russia for something in a way that doesn't make too much sense once you look at it for more than five seconds, yet sounds superficially convincing. Things like that are always unfortunate when you could leverage more substantial criticism instead; hardly a tall order with Russia.

See e.g. https://www.reuters.com/business/energy/russias-gazprom-feel...

This is a piece from TASS, written by two Russians. The golden rule of reading TASS bulletins applies now just as it did in the 20th century.

https://www.reuters.com/article/rpb-tass-connect-idUSKBN2381...

The facts are: Russia cuts off transit via Ukraine in advance of the winter to force commissioning of Baltic Sea pipeline. It's everything that East Europeans were telling the outcome of NS2 deal is going to be, but what do these jaded people know, right.

Another point for using nuclear power to replace fossil fuels as soon as possible and after that replacing nuclear with renewables.

Now we're replacing nuclear with renewables, which is just ass-backwards.

Nuclear is ridiculously more expensive than renewables. Now is when you replace the fossil fuels with renewables, while you still have fossil fuels in the mix to provide base load capacity, and once we’ve hit the threshold where we need more base load, and if storage hasn’t gotten cheap enough, is when you start bringing a few nuclear plants online.
Maybe in the US it's ridiculously expensive, but not in the civilized world.
Where is this civilized world where nuclear is cheap and fast to build?
In Finland, brought from Areva-Siemens.

https://en.wikipedia.org/wiki/Olkiluoto_Nuclear_Power_Plant#...

Total cost to owner (TVO) for this 1600 MW EPR will be little less than 6 billion euros and the rest of the cost (5 billion euros) will be paid by Areva i.e. French citizens as taxes. Building of the plant started 2005 and after the latest delays the reactor is supposed to go critical for the first time during January 2022. It was supposed to be ready during 2010.

As you can see: Cheap and fast to build.

Areva figured that this was an easy way to open the European nuclear power plant markets after the political damage to the industry due to Chernobyl. They did not take into account the fact that a lot of the professionals required were already retired and at the same time the safety regulations were much tighter than before.

> After the construction of the unit started in 2005, Areva began constructing EPRs in Flamanville, France, and in Taishan, China. However, as of 2019, the construction of the EPR in France is ten years behind schedule.[35] Taishan 1 in China became the first EPR to start power generation on 29 June 2018,[36] and the second one (Taishan 2) came online in 2019.[37]

Sounds like it has a lot to do with the regulations/regulators.

It has a lot to do with the regulations and probably more to do with the fact that in Finland they require the regulations actually to be fulfilled. This was written in the contract and Areva-Siemens was aware of the requirements at the time of the signing. They gambled and lost.

Interestingly the City of Helsinki is now considering compact nuclear reactors as a replacement for the energy source required for district heating.

https://yle.fi/uutiset/3-12098463 (in Finnish only)

Currently they are running on coal which is to be replaced by a bio fuel (wood chips) based power plant by year 2024. Many are not happy about the projected increase of traffic from trucks bringing in the bio fuel. The nuclear option will not happen due to too many diehard Green party voters in Helsinki but it is a sign of the times. Even the Green party in Finland is at least partly supportive to nuclear power.

We probably agree that the reactor in Taishan might be less safe than it is designed to be, might have some critical stress parts made of cast pot-metal, and so forth.

Do you believe the regulations/regulators in Europe are acting reasonably? You could try to argue that extreme risk aversion is the better failure mode, but that’s hard to prove in the long term.

Extreme risk aversion is costly and probably causes on average more damage to the people than operating based on a realistic risk assessment. Problem is the out of proportion fear of ionizing radiation fuelled by the campaigns of the various Green movements.

I am pro nuclear power due to the fact that producing the same amount of energy using coal power causes more loss of human lives. This has been true even when comparing just the real radiation exposure from the fly ash of an operating coal powered plant and the maximum allowed radiation exposure from a nuclear power plant. It is still true when comparing the loss of lives per produced energy when both the Chernobyl accident and the Fukushima accident are accounted for.

> [...] Building of the plant started 2005 and after the latest delays the reactor is supposed to go critical for the first time during January 2022. It was supposed to be ready during 2010.

How is 17+ years (with a 12+ year delay) "fast"?

It is not. And the total cost of 6+5 billion euros for the nuclear power plant is not cheap.

Due to the Chernobyl and Fukushima accidents any nuclear power projects today are always an uphill battle with the increasingly difficult to fulfill regulations. At the same time there will be strong political pressures from outside sources like Greenpeace.

If the safety regulations for cars were as stringent with respect to the risks involved there would be no cars at all. Even walking on the streets would be forbidden without using a helmet.

Russia ? Floating nuclear power station
Russia probably does not count as being a part of the civilized world. Even Finland is a questionable case due to the polar bears walking all over the streets of the capital Hell-sinkit.
> Russia probably does not count as being a part of the civilized world.

From the rest of your comment I gather you were joking, but please don't post nationalistic flamebait to HN. It's really easy for it to turn into nationalistic flamewars, which are particularly tedious and nasty and also relatively avoidable.

I like Renewables but, on a simplistic napkin math, nuclear is stabler, produces more and for longer, something like 2x or even 4x cheaper.

That said, if people consumed less we would not need that much energy / impact.

As more people buy electric cars they will consume significantly more electricity than they did before. There’s also many on here talking about switching home heating to electric heat exchangers.

Reducing electricity consumption is not going to happen. The bulk of the green movement today hinges on tons of net new clean electricity generation.

There may be differences about mobility in the future. Also I read that house insulation was the way to go. Semi passive temperature control.
Once you reach the point where renewables cannot be added you have no base load left. The fossil fuels weren't there to supply base load, they were there to fill in when the renewables weren't producing. Adding nuclear at that point would make no sense.
Other way round: since it takes 5-20 years to get a nuclear plant built, the rollout of renewables needs to happen as fast as possible, and maybe the nuclear industry can catch up.

If nuclear made economic sense it would get VC funding.

> If nuclear made economic sense it would get VC funding.

This isn't the next unicorn startup, we're talking about energy sovereignty and the future of humanity. If the only thing we care about is the economy we'll never get out of this....

Well 20% of US uranium production capacity was sold for charitable donations to the benefit of a certain former Secretary of State. I’m not sure how much has been plundered during more recent administrations, but I wouldn’t count on anybody with real authority to do the right thing. Time to join team Visigoth.
More accurately a sale was approved by the Committee on Foreign Investment in the United States (CFIUS), chaired by the Secretary of Treasury and requiring the signatures of the Secretaries of Defense, Commerce, State, Energy, Homeland Security, Justice, as well as the Office of the U.S. Trade Representative and Office of Science & Technology Policy. All signatures being equal. It is impossible for any Secretary of State to approve of a sale like that alone.

https://home.treasury.gov/policy-issues/international/the-co...

Right? strange to assume nuclear power plants could be built over night! while discrediting that renewable on components production levels could be easily scaled.
No, correct way around. Rollout of renewables to the scale that nuclear can achieve in 5-20 years is practically impossible.

The best time to plant a tree was 20 years ago. The second best time is now.

> the scale that nuclear can achieve in 5-20 years

This is just fantasy. "Can" is a very long way away from "will". And almost all of the reactor projects currently under construction have time and cost overruns.

The best case for the UK in five years is that we manage to finish constructing one (1) reactor that is currently under construction.

Worse yet, it is the only one of eight plants announced by the government in 2010 to have actually begun construction (which started at the end of 2018). And 2010 wasn’t even the first government announcement about wanting a new reactor.
“Can” is a very long way from “will”. But “impossible” is even further. That’s my point.
Wind and PV grew by roughly 200-240 gigawatts in 2020. Total current worldwide civilian nuclear reactor electrical capacity is about 400 gigawatts, with another 60 GW under construction and about 100 GW planned.

Even if renewables stop their current exponential growth and only grow linearly, even assuming a mere 25% capacity factor for renewables and 100% for nuclear (neither of which is true), even assuming all currently planned and under construction reactors are completed and no existing reactors are turned off, renewables still exceed nuclear by about 2028. I’m expecting it to be a lot sooner than that because I expect the two (different) exponential trends in PV and wind to continue for at least another doubling period.

I’m still in favour of expanding nuclear power: it’s much safer than generally believed, it saves on storage requirements and intercontinental HVDC (we might get enough battery factories or extra copper/aluminium mines in time but I don’t want to count chickens before they’re hatched), and while it’s expensive it is (currently) still cheaper than batteries.

But I’m not expecting nuclear to be a big player, I just like diversity of supply for its own sake.

> If nuclear made economic sense it would get VC funding.

Of course it wouldn't, VCs only care about things that have a potential for rapid growth. A nuclear plant doesn't (and neither do most businesses that provide value in a sustainable way).

A nuclear plant can grow rapidly, but when they do it tends to make a lot of people very angry and is regarded as a bad move.
Smartest thing to do would be to allow the US Navy to run and operate land based nuclear reactors based on their technology. Build good will for the Navy and maybe use the money to finance their operations. They've operated miniature nuclear reactors for decades without a single incident. They seem to be decades ahead of the public sector in terms of technology
The US Navy Nuclear Propulsion program more or less self-regulates.

I'll add that naval reactors are small and floating - one of the advantages of the "small modular reactor" designs is that the production time and cost are both much less than that of large plants, which makes the risk calculus much more palatable for investors.

Everything bad for the climate is having price surges lately. See also Bitcoin.
It’s almost like we thought that coal- and nuclear- shaming was all the planning that we needed to switch to renewables and avoid an energy crunch.

We mock Bitcoin, but China isn’t just shutting down Bitcoin, but also its steel and aluminum foundries, its semiconductor fabs, and adjacent industries to cut power demand. They need to limit blackouts during winter to stave off popular uprisings.

Hadn't connected the Bitcoin ban to the power shortages but in retrospect it seems obvious
Do you have a source on that? Not that I doubt it but if that is true, then we will see some serious market issues in the near future.

Steel is already high and the chip issues are bad too.

I agree with you, and I think that they're preparing for the season as they need energy. Loss of further resources might greatly affect China.
Isn't all inflation exponential?
Mathematically, yes. (More-or-less.)

Commodity price fluctuations usually are not.

But "rising exponentially" seems to have become a way to say "going up very fast, and you should get excited about it!".

It is compound growth (because we dont really allow deflation for various social and economic reasons) therefore it grows exponentially
This is going to be a major problem this winter because this is due to supply. And NG/oil supply is low too. Investing in coal is not considered a good look anymore and so mines have closed.
Price instability in fossil fuels is a big boost for renewables. The industry has always been boom and bust, but now consumers have a choice.
Ah, so it looks like coal still has a use after all, like Bitcoin.
People fail to realize that modern economic activity is a small veneer on top of vast energy consumption. Coal & gas prices exploding will reflect into exploding inflation, which will reflect into imploding purchasing power before long.
It's been a good run all in all :cheers:
