You clearly have no understanding of German energy consumption. Natgas is being used by the industry and for domestic heating. Nuclear power plants were used for electricity generation. Even if we had 100% in spare nuclear capacity above baseline consumption, we would still be building these LNG terminals. Absolutely nothing would have changed regarding the current gas and oil situation.

Yes, and people are saying this is exactly the problem. There is no law of physics (or even economy) that demands industry and domestic heating must use gas. It is the result of 30 years of not building enough power plants.

Replacing a domestic heating system is significantly more difficult than adding new electricity plants. Domestic heating is a completely decentralized problem. If you wanted to change everyone over to electrical heat, yes it could be done. But not rapidly. And swapping out gas radiator boilers for electric options can be very difficult and costly.

There is no law that says that you must use gas for heat. But once you have that installed base, you can’t just switch from gas to electric heat overnight. It will take decades to make that change. Even if all of the equipment was available (and it’s not), it would take a team of 3-5 workers 2-3 days to convert each home. And that’s assuming a simpler gas -> electric boiler swap without needing to upgrade electrical service panels/etc. This type of change can get complicated quickly for just a single house. Multi unit homes would be more complex. Now factor that over all other homes/buildings and you can see that the number of workers required to do this rapidly don’t exist.

Even in the US, there is a push to phase out gas heat in many locations. But it’s a phased rollout with a plan decades long.

Could this be a longer term plan? Definitely. But with a quick turnaround? Not really.

I don't know what you are talking about. It's literally as easy as buying a $15 electric space heater from the next store and plugging it into an existing wall outlet. The rest is just aesthetics. Electric water heaters are also affordable, small and easy to install yourself.
Re:The five-year engineering feat Germany pulled off in months by dbrgn on Sunday December 11, 2022 @05:18PM (#33948197)
Are you saying that hot water based central heating systems with radiators should be replaced by throwing an electric heater in every room? You can't be serious.

There are quite a few things wrong with that, first of all the efficiency is terrible (that's why they're banned in Switzerland since 2009), secondly the house installations in a lot of homes would probably not be able to cope with the power required to heat all rooms (in my apartment in Switzerland, the fuse would pop out when I turn on two of those 2000W heaters). Third, it's far less convenient if you need to set the heat in every room separately, instead of turning on/up/down/off the central heating system when the outside weather changes.

Re:The five-year engineering feat Germany pulled off in months by jupp0r on Sunday December 11, 2022 @08:00PM (#33949546)
These $15 space heaters have thermostats, you set a temperature and they heat the room until that temperature is reached. I'm sure you can get a $50 version that speaks smart home protocols of your choice so you can program schedules if that's what you want. Not sure how turning valves on several water radiators per room is more convenient.
Re:The five-year engineering feat Germany pulled off in months by mbreese on Sunday December 11, 2022 @09:42PM (#33950244)
These cheap (seriously a $15 heater can’t produce enough heat to cover a room larger than a small bedroom) heaters also can’t be controlled with a central thermostat. Water radiators (or electric heat pumps, etc) can be controlled for the whole home, or by individual locations (without needing to manually turn valves).

In fact, at least in the US, space heaters aren’t allowed to be automatically turned on by any means. They require a person to start it manually each time you want heat. Because they aren’t permanently installed, it is a potential fire hazard. A pet/kid/etc could run past it and knock it over. If that happened near a blanket or pillow, the fabric could catch fire.

I can’t imagine being able to buy something less safe in Switzerland.

I’ve been waiting a couple weeks for my gas furnace to be repaired (everything’s slow in Canada these days) and ended up buying a couple similar little electric heaters since winter’s pretty much here.

I’ve got no dog in the Euro energy debates, but I can say that anecdotally it’s been fine staying warm with electric heat in the interim. Obviously having a single centrally controlled thermostat is preferable, but it is really a vanishingly negligible task to flip heater a switch on or off.

Re:The five-year engineering feat Germany pulled off in months by mbreese on Monday December 12, 2022 @01:41AM (#33951662)
I said a central thermostat. This is the context I was referring to. As in a remotely controlled heater where the thermostat is on the wall as opposed to on the device. This is what you’d need to use to keep a home heated while you aren’t there. I happen to have a space heater on right now next to me. It has a very nice remote app on my phone. And it is very clear that the heat function only works from the device itself (due to a legal requirement to support UL 1278). If your cheap heater has a built in thermostat that turns itself on, that’s great… while you’re there watching it. But I can’t say that’s something that I’d ever feel comfortable leaving always plugged in. They are only ever supposed to be used while attended - for a reason. The updated version of the product you linked to (2022 digital version) even has an automatic shutdown timer. You have to manually start it again after that shutdown.

I also have a permanently installed electric heater installed in the wall in a different room. It does have a permanent thermostat that can start/stop automatically. It’s quite a different beast from a $20 space heater with its own circuit back to my breaker box. It works pretty well, but portable, it is not. It was also much more than $20.

But, back to your original point — are you really suggesting replacing the entire German heating infrastructure with $20 ceramic heaters from Amazon? How is that a remotely viable solution? These are devices meant for heating a small office. If you want to heat an apartment or house or city, you need different options. And changing those over takes time and more consideration than buying a bunch of $20 space heaters.

Re:The five-year engineering feat Germany pulled off in months by jupp0r on Monday December 12, 2022 @02:38AM (#33951983)
My point was that replacing an existing central gas posered water circulation heater with electric heating is easy, cheap and fast (operating it might be more expensive, or cheaper depending on electricity prices). It's not "Replacing a domestic heating system is significantly more difficult than adding new electricity plants.". I have done so myself on a relative's house in a weekend including installing an electrical water heater (solar panels in roof make this very inexpensive to operate). Of course you wouldn't use cheap chinese portable heaters as a permanent solution, but it would totally work, they are 100% efficient in converting electrical to thermal energy.

Your point that you can't have central temperature controls with electric heating is just absurd, I learned how to build this in first semester of electrical engineering.

Replacing a whole country's infrastructure to go from electric heat to depend on community steam boilers or gas heating instead is infeasible due to the logistics involved as those are major infrastructure projects. The reverse does not seem true. Replacing whole house heating with cheaper per-room heating seems like a downgrade because, well, it is. But there's a war going on and sacrifices have to be made. If you don't think shitty electric space heaters is not luxurious winter living I'd largely agree, but the thing is poor Americans are able to survive through harsher winters than, say, Berlin gets with these terrible heaters.

We (specific subsets of humanity) just completed a massive government led undertaking to distribute a brand new vaccine to huge swaths of population, which involved an insane amount of logistics. And then also RAT kits. On the heels of that, you're telling me that distributing a small box that doesn't need to be stored at -20C or else it goes bad, to every household in a country is simply too hard and we shouldn't even bother, and just let people freeze to death? I mean, yeah it seems a bit late to start. The best time to start such a project would have been Friday, February 25th, 2022. The second best time though is now.

> Replacing whole house heating with cheaper per-room heating seems like a downgrade because, well, it is. But there's a war going on and sacrifices have to be made.

This would be pointless in Germany, though, since there isn't enough electricity in the European grid to make a short term switch for this many people. (Also the price for electricity is already still much higher than for NG).

For this year, it's already getting too late to act, apart from trying to make as much LNG as possible available to the public.

For the future, electrification of Eueope will need large investments in stable&affordable power production with incentives for homeowners to make the switch as it comes online. Typically such an incentive would be to gradually introduce a tax on NG that will eventually be high enough to squeeze it out of the market.

The best time to start this would have been 20-50 years ago.

I've heard a few people say this, but it's not true - the efficiency of electric heaters is 100%. They're only detrimental when they run off of fossil-fuel based power plants. Instead of making silly laws banning symptoms, our focus should be on removing the pollution at its source.

a) I think many people already have some heaters sitting around somewhere.

b) If a country like Germany can't, within a couple of months, produce something as simple as resistive heaters in significant numbers, something must be seriously wrong. They consist of a cheap case, resistive wire wound into a coil, a fan, and a couple of switches (main power switch, safety switch that turns it off when it tips over). If a design takes 3 minutes to hand-assemble after the easily automatable parts (e.g. stamped sheet metal case, coil) have been made in great numbers, then a single factory with 100 workers will churn out 16000 per 8-hour day, or a million in 3 months.

c) even if Germany can't, China can. Maybe not enough for everyone but enough to make a significant dent in gas consumption, together with the ones people already have

d) everything that uses electricity is an electric heater. Worst case, heat a large pot of water on the stove.

I don't believe your apartment in Switzerland only has one 16A circuit it can draw from, that wouldn't be up to electrical code in most European countries that require one 16A circuit per room. No expert in Switzerland electric code specifically though. The last apartment in Germany I lived in (1 bedroom 1 bathroom) had 4x16A circuits and separate 3x16A for the electric kitchen stove.

Re:The five-year engineering feat Germany pulled off in months by bcrl on Monday December 12, 2022 @02:28PM (#33959010)
No, that isn't a realistic option. My grandparent's place over in Germany is a huge 3 story place heated by a hot water boiler system and plenty of rooms. There's absolutely no way that you can heat that place with electric heaters in every room without blowing fuses constantly, and if you switch over to an electric boiler, there's a good chance the connection to the electrical grid is inadequate as it was installed 70+ years ago when life was very different. Europe is not like north American as older housing stock is not easily retrofitted without significant costs being incurred. Plus there are plenty of high density buildings as land is precious and expensive, so we're not talking about 1 story bungalows being the norm. This is what happens when towns have already existed in place for centuries.
Re:The five-year engineering feat Germany pulled off in months by trashtester on Tuesday December 13, 2022 @06:25AM (#33967392)
My house is similar to that of your grandparents. The house was built 70 years ago, and originally it had a coal fueld boiler, which was switched to a heating oil boiler (twice, I think) with the one in place when I bought it also having a 6KW electrical backup coil.

In 2020 my country (Norway) made it illegal to use fossil fuels for heating, so I had to upgrade my grid connection and buy a couple of space heaters to account for the days where 6kW is not enough.

At the time (2020), electricity was still very cheap here, due to Norway being self supplied with almost-free hydropower. Now that we're able to export all our surplus electricity (and then some), and we're seeing German electricity prices here, I suppose I need to get a heat pump.

TLDR; Given a couple of decades, it's perfectly possible to move the population away from fossil fuel heating IF you have large amounts of affordable electricity.

Re:The five-year engineering feat Germany pulled off in months by cycomanic on Sunday December 11, 2022 @06:20PM (#33948739)
As long as you are using fossil fuels to generate electricity using electric space heaters is counterproductive because you actually produce significantly more CO2 than just burning the gas directly (this applies to France as well btw). The space heater comment also let's me to believe that you never lived in a country that requires proper heating.

Now heatpumps are a different issue, however they require to upgrade insulation as well.

Re:The five-year engineering feat Germany pulled off in months by jupp0r on Sunday December 11, 2022 @07:53PM (#33949496)
The efficiency of electricity production has no influence on the amount of work it takes to convert heating from gas to electric.

Why would you want to use fossil fuels to generate electricity anyway nowadays?

I've spent several months above the polar circle and lived in Germany and Minnesota where it gets much colder than in France. Heating a 2 bedroom mountain cabin in winter in Sweden in -36C works fine with 3x2kW electric heaters. It's basic physics, there isn't any advantage to using gas given the same power ends up being transferred to the inside of the building as heat energy.

> The efficiency of electricity production has no influence on the amount of work it takes to convert heating from gas to electric.

Sure it does, it directly effects prices. Also the efficiency affects how much CO2 you generate, you don't win anything if the absolute amount of CO2 goes up.

> Why would you want to use fossil fuels to generate electricity anyway nowadays?

Because the system has a big inertia? AFAIK there are no western countries who generate 100% of their electricity fossil free, Norway and New Zealand come quite close but are not 100%. For most countries its still around 30% at least which is fossil.

OK then do the exercise, the price for electricity is ~0.28 kWh, how much would it cost to heat that cabin for the year (and we haven't heated water yet).

Most electrical codes only require updates (to bring the system into compliance) when there is work being done. So if you don’t need to add a circuit, your home may still be wired as if it were the 1950s (or earlier!).

This is part of the hidden cost and complexity. For someone like the parent, you’d have to rewire an entire home. How long do you think that will take? If you seriously wanted to move an entire country over to electric heating, you’ll have all sorts of these edge cases. There simply isn’t a way to make a switch like that in a rapid manner.

Re:The five-year engineering feat Germany pulled off in months by withinboredom on Monday December 12, 2022 @01:44AM (#33951677)
Yes, my home is wired from ancient times. Last year we had monthly blackouts in our home. It took multiple electricians to figure out that our home wasn’t wired to code, and finally to learn that two wires had melted together and were a fire hazard. It was easy to replace them but, impossible to rewire the house to bring it up to code. All the walls would have to be ripped out, which just isn’t feasible on a realistic budget.

The service coming in from the neighborhood is only rated for 25 amps too. They’ll have to lay new cable to get 50 amps and support a heat pump. There’s been some talk on the block about pooling money to pay for it, but nothing serious yet.

Re:The five-year engineering feat Germany pulled off in months by mbreese on Monday December 12, 2022 @02:27AM (#33951919)
Anytime you’re talking about a large population, outliers are going to be found pretty often. Even if only 5% or the homes in Germany are like the parent/sibling post, that’s still 2.1M homes (Google said Germany has 42.5M homes, so that’s what I used).

So, even if the average home could be switched over easily (which, I still think is wrong), that’s still would leave a lot of people without many good, financially feasible, options.

I think you're optimistic if you think we'll have zero carbon electricity production in a few years, at a scale that will allow us to replace all NG and oil heating with electrical, especially without heat pumps.

Even if we make it a primary priority, and try to maximally ramp up both wind, solar and nuclear production (+ storage as needed), I don't think we will be able to do it in less than 30 year, 20 at best.

Re:The five-year engineering feat Germany pulled off in months by yongjik on Sunday December 11, 2022 @04:20PM (#33947657)
Well, I don't think anyone's suggesting it can be done overnight. So, of course, we will need a stopgap measure (of LNG terminals). For now.

IMHO, what people demand is that Germany should recognize that the current crisis is the fruit of multiple decades of bad energy policy. If we don't, twenty years later, we'll still be saying "Yes, sadly, Germany is still burning gas, but you can't convert it overnight! What do you want?"

It's the result of cheap fossil fuels, provided by Russia.

There is no shortage of electricity in Germany, so there was no economic interest to build more nuclear power plants? Germny even exports electricity to France, which has a lot of nuclear power plants (many of which currently don't work).

We don't even know where to safely put the waste for the next million years. Germany doesn't have the huge inhabited areas like the US - and even they have not solve that problem yet.

Re:The five-year engineering feat Germany pulled off in months by Scea91 on Sunday December 11, 2022 @02:46PM (#33946745)
Germany export to France is an uninteresting information without context. Due to the energy mix the energy is exported in production peaks when it is cheap (sometimes prices are negative) and imported back when there is shortage for higher prices. Also the whole flow network needs to be taken into account and germany imports also from other countries.

You can’t currently build a reliable electric grid with wind and solar alone so you need either nuclear or fossil fuels.

> Yes, and people are saying this is exactly the problem. There is no law of physics (or even economy) that demands industry and domestic heating must use gas. It is the result of 30 years of not building enough power plants.

No but there are laws of chemistry.

The point the previous poster was trying to make is, that the industry needs natural gas as a precursor product, mainly for the chemical industry. Obviously, you cannot replace that with electricity easily. Over 12% of Germany's natural gas use is purely for the chemical reactions it provides within the chemical industry. A further 10% is for use in the metal industry where gas also has been notoriously hard to replace as it's not used for its energy value alone but for providing reduction reactions.

What you say basically is, not only Germany should have kept on building nuclear, it should also have developed new hydrogen based industrial flows for all these sectors alone, things that exist nowhere on this world on actual scale.

So LNG terminals would have been necessary in any case. Germany had none due to the over-reliance on Russian gas.

Otherwise I will not comment on the difficulty of replacing domestic heating, which IS a huge block of gas usage, on the scale of a whole country, as others have already done this.

Re:The five-year engineering feat Germany pulled off in months by merry_flame on Monday December 12, 2022 @09:46AM (#33955134)
No law of economics… are you that sure? France is the poster boy of nuclear energy and has been pushing very hard for electric domestic heating over the years and yet it simply has almost never made any sense for homeowners to opt for electric heating rather than natural gas. Indeed, though French electricity prices have always been probably the lowest in Western Europe, it still always comes up some 50% more expensive than natural gas. The only major reason property owners switch to electric is that it's cheaper to install, so using in it in rentals shifts higher energy prices onto tenants while property owners benefit from lower investment costs. Clearly, not building more power plants isn't really what went wrong here.

Norway banned fossil fuels for domestic heating in 2020. Which it could do due to having built out electricity generation 4-5x the GW/capita compared to most of Europe, 100% which is renewable (+some 10-20% extra available for exports).

Hydro makes this simple. Nuclear makes it possible. No other approaches have been demonstrated that allows this without fossil fuels at scale.

Re:The five-year engineering feat Germany pulled off in months by cycomanic on Sunday December 11, 2022 @06:16PM (#33948707)
There is a lot of industry that has absolutely no other way than to use gas. There was an article about a copper wires manufacturer in a German magazine a while ago. They need a lot of heat to melt the copper, and currently the only economically feasible way is natural gas. Electricity just can't get you the temperatures and alternatives like hydrogen just don't work yet (they actually have been running tests for years on this).

The issue is if they don't have gas, transitioning other things to electricity becomes difficult, because you need copper.

Isn't burning gas for heat more efficient than first produce the power to heat sthg?
Re:The five-year engineering feat Germany pulled off in months by gruturo on Sunday December 11, 2022 @04:24PM (#33947703)
Not if you use a heat pump, no. Modern ones have very high efficiency (above 300% as they're not actually using energy to make heat, just to "move it around") and work even in very, very cold temperatures. But you don't install tens of millions all over a country in a matter of months - you quickly run into bottlenecks like production, distribution, certified installers, etc.
Re:The five-year engineering feat Germany pulled off in months by trashtester on Tuesday December 13, 2022 @07:18AM (#33967898)
You're not likely to get 300% efficiency when it really matters, in colder climates. The temperature outside my house is around -10C now, and closer to -20C at night this week. Keeping my house warm requires around 6-10KW constantly atm, which I could perhaps reduce to 5-8KW with a heat pump (some heating will come from other appliances, like computers, fridges, etc).

Or I have used the oil boiler in the basement, if Norway didn't ban that in 2020. That would have freed up enough electricity for several homes in the UK or Germany.

Electrical heating is fine if all electricity produced is from hydro, nuclear or wind/solar, but it makes less sense if the grid relies too much on fossil fuels.

Re:The five-year engineering feat Germany pulled off in months by toast0 on Sunday December 11, 2022 @04:19PM (#33947641)
Depends. Better to burn gas for direct heat than burn gas to produce electricity and then use resistive heating.

But you do have to transport the gas or electricity to the heating site, and I don't know how that adds up.

Also, if conditions are right, you can use electricity to run a heat pump and move heat from the outside air to the inside air; depending on the details, you can move a lot more watts of heat then you spend operating the heat pump. This can be more economical than direct heating.

Re:The five-year engineering feat Germany pulled off in months by neltnerb on Sunday December 11, 2022 @04:19PM (#33947636)
In a sense, but if the worry is carbon and energy security then domestic renewables and nuclear look a lot more attractive.

Heat pumps are great and super cool but if you include the efficiency of generation it's unlikely to be more energetically efficient, yes.

It's close though, natural gas combined cycle plants are very efficient for what they are. And if the heater is electric, substitution for other electricity sources is possible... unlike now.

Re:The five-year engineering feat Germany pulled off in months by jupp0r on Sunday December 11, 2022 @04:27PM (#33947724)
It is, but why would we want to burn gas and invest in gas infrastructure instead of carbon free technology? Electric heating works great for any future technology we end up using.
Re:The five-year engineering feat Germany pulled off in months by sorenjan on Sunday December 11, 2022 @10:20AM (#33943883)
Why are you still burning fossil fuel to heat houses? If you had stable electricity you could use heat pumps instead. Seems like fossil gas has been too cheap for too long, which have incentivized dependency on it despite the CO2 external cost.

Are there any plans on using waste heat from industry combined with district heating anywhere? Biofuels? Subsidized insulation retrofitting?

Re:The five-year engineering feat Germany pulled off in months by HDThoreaun on Sunday December 11, 2022 @11:36AM (#33944644)
Heat pumps have only recently become economically in climates like Germany’s. Most people don’t want to replace their furnace until it breaks or needs expensive repairs.
Re:The five-year engineering feat Germany pulled off in months by ImprovedSilence on Sunday December 11, 2022 @11:48AM (#33944790)
It’s been economical for 30+ yrs for Germanys climate, they just have older housing that’s never been updated. Every heat pump has backup source of heat too. Which will be electric coils or gas usually, so you don’t even have to give up gas heat for the really frigid days.
Re:The five-year engineering feat Germany pulled off in months by pbhjpbhj on Sunday December 11, 2022 @11:55AM (#33944863)
I'd say in UK heat pumps are only just down to affordability domestically. If capital is cheap for you then perhaps they've been affordable much longer, but baseline costs are only recently noticeably low enough for me to consider it ... possibly when I look next time it'll be out of reach again given the weak pound and massive cost of living increase.

I'm hoping to get a heat pump next Summer.

Re:The five-year engineering feat Germany pulled off in months by jacquesm on Sunday December 11, 2022 @12:03PM (#33944955)
Supply is a real problem at the moment. If you really plan on getting one I would order it well before you have the installation planned.

Thanks for the advice. I was hoping to have time over Christmas to start looking, I've done a little preliminary research. There are, as ever, complications (possible extension?).
Re:The five-year engineering feat Germany pulled off in months by jacquesm on Sunday December 11, 2022 @04:46PM (#33947904)
It's tricky stuff, best to befriend a local installer so they can help you choose. In the end after doing all the numbers for our house the simplest solution for the next two years (as long as we still have netmetering) was to install ample solar and postpone the heatpump that way by the time we will buy the heatpump the solar installation will already be halfway towards being paid off, with the current electrical rates here the ROI on solar is incredible, and running a heatpump off the solar system in the winter isn't very effective, at a minimum you'll need a battery set up for that. But even in October we managed to be net positive with respect to the grid which helps to offset the cost of the gas.

But in 2025 it will be a completely different story which will likely require yet another investment. I'm kind of wondering how people that can't just do that kind of thing are going to cope, it is a worrying development. Of course it doesn't help that the measures to control the prices of energy here effectively benefit the large producers at the expense of the people that decided to go for heatpumps early on.

But as long as the countermeasures still split by gas and electricity usage it is to our advantage to get as close to the cap as possible on natural gas. Ridiculous, but the difference is too large to ignore.

Re:The five-year engineering feat Germany pulled off in months by ImprovedSilence on Sunday December 11, 2022 @11:59AM (#33944907)
Yeah there’s no denying that it definitely helps that electricity is a good bit cheaper in the US, making gas v. Heat pump heat pretty much on par in the northeast at least.
Re:The five-year engineering feat Germany pulled off in months by stefan_ on Sunday December 11, 2022 @12:59PM (#33945569)
It hasn't been, though - not for any particular technical reason, mind you. Yes, they are 3x as efficient, but meanwhile we have heaved so many taxes and other costs on private electricity prices (to keep industry use cheap) while natural gas had stayed dirt cheap that the upfront capex really made no sense.

If they weren't so impractical, everyone should have been buying gas turbines to make their electricity - that's the level of market failure we are talking about.

If the government can subsidize solar installations, can't they just as well subsidize furnace replacements? It's interesting which parts of this problem people are eager to tackle, and which parts they completely let their own side down on.

The incentives and the rhetoric are poorly aligned.

Until fairly recently heat pumps didn't operate at the temperatures regularly seen in the northern US and Canada. Hard to shift a lifetime of the choices being expensive resistance electric heating or (comparatively) cheaper burning fuel.

In rural Canada you'll find plenty of oil furnaces with their own tanks as well. Some of those are 30 to 40 years old and all of them are terribly inefficient.
Re:The five-year engineering feat Germany pulled off in months by hn_throwaway_99 on Sunday December 11, 2022 @01:54PM (#33946172)
And they are expensive AF to run. I had family members who had an oil-heated house on the Northeast US, and it was close to $2k a month to hear in the winter months (the house was large, something like 3000-3500 sq ft, but that's still an astronomical cost for heating)
Re:The five-year engineering feat Germany pulled off in months by jacquesm on Sunday December 11, 2022 @02:05PM (#33946297)

Re:The five-year engineering feat Germany pulled off in months by jacquesm on Sunday December 11, 2022 @04:55PM (#33947984)
Plenty of these old houses have much bigger problems than just the windows (which, in Canada at least in all but the very oldest houses always was double glass, even if it came in the form of an inner and an outer window).

Crappy foundations without insulation, roofs and walls with poor insulation, front door directly opening into the house instead of a separate space, almost all of them freestanding (especially rural ones) and relatively large for the number of people living there. Heating in Canada is an interesting problem. -40 Celsius on the other side of a 4" barrier is nothing to take lightly. One elderly couple that I'm aware of had begun to dismantle their house on the inside and they were burning it all up bit-by-bit to stay warm, the two of them sitting around a shitty old pot bellied stove that moved the bulk of the heat generated straight out the chimney. Stuff like that breaks your heart.

Re:The five-year engineering feat Germany pulled off in months by Spooky23 on Sunday December 11, 2022 @08:17PM (#33949683)
That is awful.

My post was a little too quick… one of my good friends was an energy efficiency expert and when I asked him for advice on replacing a boiler in our “new to me” home and he goes “don’t!”.

We did an audit and spent about $4000 on efficiency retrofit - it cut our heating bill about 25%. That was 10 years ago, and we’ll probably start looking at replacement boilers when incentives ramp up for new tech.

Re:The five-year engineering feat Germany pulled off in months by jacquesm on Sunday December 11, 2022 @09:49PM (#33950295)
That's the right approach though: any Joule you don't need to produce is one saved and even the most efficient furnace can not fix a leaky house. So the priorities are: economize (because it is free, and assuming you still can), insulate, high efficiency heat (depending on the age of the furnace, anything older than a decade is likely not HE+), self generated power in that order.
Re:The five-year engineering feat Germany pulled off in months by landemva on Sunday December 11, 2022 @08:49PM (#33949910)
I had the full energy efficiency report with infrared camera and expert's eyes and blower door test. It was enlightening. I strongly recommend first thing get the expert report and follow the recommendations.

A few years later I got another report and fixed a few more things. House cold spots mostly went away, bills went down, less outside noise, and have the same windows and furnace.

Re:The five-year engineering feat Germany pulled off in months by Spooky23 on Sunday December 11, 2022 @03:31PM (#33947156)
There are lots of options out there. My parents have a 95% oil burner that works great for heat and hot water.

The gotcha is that the efficient units require more maintenance so in some situation it’s cheaper to be less efficient.

Re:The five-year engineering feat Germany pulled off in months by jacquesm on Sunday December 11, 2022 @09:50PM (#33950306)
The latest generation (HE+) is a lot better than the ones before it which tended to erode the inner liner of the burner vessel into a nasty aluminum rich sludge that ended up clogging the drain. The newer ones do not have that (much thinner drains too).
Re:The five-year engineering feat Germany pulled off in months by twisteriffic on Sunday December 11, 2022 @12:59PM (#33945568)
Really depends on where you are. Parts of Ontario and BC you could probably get away with just a heat pump, but lots of places in the prairies you could only use a heat pump for maybe 1/2 of the winter months. It's just too cold the rest of the time, so you'd have to augment with electric or gas anyways.

With the amount of flak raised about infrastructure not being able to handle electric vehicles I can't even imagine the chaos if the prairies went electric heat.

I'd really like to see strong baseline energy efficiency standards put in provincially for new builds and a lot of investment in retrofit, but with the current political climate in the prairies that's impossible. Promoting anything that doesn't burn both oil and money is anathema.

Advocates usually don’t mention that the solution for the millions of houses with hydronic systems are usually mini-splits, which are both ugly and noisy.

Lots of people who don’t have heat pumps are rabid advocates of them. In some cases trying to ban gas heat.

In a disturbing chicken and egg problem, the heat pumps industry is not as installed and scaled up yet, which kinda refrain people from making the jump. Stories of heat pumps breaking up in November after less than ten years with no one left to fix them are not making the tech look good, whereas gas boilers routinely last 15/20 years while everyone forget them except once a year for maintenance - and once every couple decades because of geopolitics.

This will definitely change in the next few years, as heat pumps will replace "fioul" (petrol ?) boilers, which are being slowly banned.

Which will make our direct co2 emissions slightly better, and our electricity generation problems MUCH bigger...

(Full disclosure : I bought a house with a 5-year old gas boiler that I haven't had the heart to trash yet, instead investing in insulation, and a good wood furnace. My goal for 2022-2023 winter is to use it half as little as last winter.)

That's understandable considering the sudden demand spike that's ultimately because of the war. People aren't extra interested now because they want something more environmentally friendly, it's pure economics. Using fossil fuel wasn't expensive enough before since the external costs aren't factored in, so now when Putler has driven up the price of gas and oil people learn that there are alternatives, and now many of them are cheaper as well.

My question isn't "why aren't you switching now", it's "why haven't you switched during the previous 20 years, when we've all known about climate change"? And on top of that there's the strategic issue with relying on Russia.

>>Why are you still burning fossil fuel to heat houses? If you had stable electricity you could use heat pumps instead.

You do realize that in many countries - including the US - a very large portion of electricity is still generated from fossil fuels? Until there is enough electricity generated from wind/solar/nuclear, switching to an electric heat pump just switches where those fossil fuels get burned, i.e. it pollutes someone else's neighborhood instead of your own.

Re:The five-year engineering feat Germany pulled off in months by sorenjan on Sunday December 11, 2022 @04:33PM (#33947794)
Burning fossil fuel isn't primarily about polluting neighborhoods, it's about polluting our shared atmosphere. If 20 000 houses use electricity from one oil burning power plant it's relatively easy to capture the carbon emissions from that one plant, and to replace the plant with other power producers eventually.

Looking at electricity maps: Currently burning 28GW of very dirty coal, 46% of demand, 72% of emissions. 12GW of gas, 19% of demand, 17% of emissions. Wind+Solar combined is only supplying 7% of demand.

They decommissioned ~20GW of clean nuclear power over the past 20 years. Whatever way you cut it that’s a huge mistake for the climate (not to mention economy). That replaces most of the coal in that picture. Or replaces all of the gas and then some in that picture.

Why do you say nuclear is as clean as diesel? That is clearly not true.

CO2 emissions equivalent to wind and solar (actually slightly better). Safety (deaths per kWh) also equivalent to wind and solar. And land use much much better. Waste is tiny for the energy produced and easily contained unlike other industries, which is why no one has died from waste.

So basically you're rejecting the safest power source with the least environmental impact, and the only source along with hydro that has actually empirically (in the real world) accomplished deep decarbonization of an electricity grid (e.g. Ontario, France, Sweden).

Nuclear waste has a lifecycle of 1000s of years. The heat surplus kills river life. If things go southwards, whole regions are no longer livable for us humans.

Nuclear energy is climate change wise, surely a good deal but environment wise and human population wise, the thing is not that easy.

And nuclear waste is only easy contained if you are the US, Russia, Canada or Australia. Because otherwise you do not have a significant sized land area where you can burry that waste without creating massive problems.

The clean energy revolution was promoted by the Green party in 1998-2005 (including turning off the first nuclear power plants).

It was the string of conservative governments that followed it that neglected (and, at times, actively sabotaged) the build out of renewable power sources.

Re:The five-year engineering feat Germany pulled off in months by thomascarney on Monday December 12, 2022 @04:12AM (#33952582)
SPD (center-left leaning party) has been junior partners in every one but one of those conservative governments.

German politics are also very collaborative/compromise driven, so it's a mistake to think the outcome would have been drastically different, had we had a SPD/Green coalition rather than a CDU/SPD coalition the last 16 years.

This is especially the case, given that parts of the SPD were and continue to be on Russian payroll.

Ultimately, renewables are very challenging from a technical perspective for a densely populated country with energy intensive industries and limited offshore wind options.

Why? At that point resistive heating could be cheaper than gas, and remove at least some of the demand.

Re:The five-year engineering feat Germany pulled off in months by _visgean on Sunday December 11, 2022 @09:59AM (#33943726)
gas plants are used for short term electricity generation. If there is more demand than production can sustain the transmission operator will buy the extremely expensive electricity from gas sources. This price will be shared by everyone.. https://clouglobal.com/european-merit-order-energy-trading-o...

Energy use in the form of Natural gas for heating and industrial use dwarfs all electrical energy consumption in Germany - something like 8-10x at least if you measure it in joules.

It’s not an uncommon situation in northern climates. Natural gas has a LOT of thermal energy, is pretty cheap per BTU/joule, and thermal energy is very useful.

Re:The five-year engineering feat Germany pulled off in months by jeltz on Sunday December 11, 2022 @12:28PM (#33945222)
Hmm, not sure I agree with northern climates. Russia uses gas for heating but Finland, Sweden and Norway do not.
Re:The five-year engineering feat Germany pulled off in months by lazide on Sunday December 11, 2022 @02:30PM (#33946592)
Interesting - at least for Finland, biomass (aka wood), and oil are common for folks out in the sticks, and district heating and electric resistive or heat pumps are more common in settlements or cities.

My guess is the difference is due to infrastructure? Finland is widely dispersed, and it’s expensive to run pipelines for natural gas in frozen ground.

So something naturally present (wood), tankable/drivable (oil), or centralized in a settlement (district heat) wins? Similar with Norway and Sweden?

Russia is a bit different because it has a lot of oil and natural gas, but even then outside of a major city, probably wood wins?

Germany has a much milder climate, and is much denser, but not all centralized, and especially after the wars, centralized heating probably seems like a dangerous idea.

Was pretty cheap.

Re:The five-year engineering feat Germany pulled off in months by lazide on Sunday December 11, 2022 @02:25PM (#33946537)
Compared to freezing to death, still pretty cheap. It’s worth noting, that 10x current electrical consumption is assuming a conversion (with electric) using very efficient heat pumps to produce the heat when using electricity.

If doing resistive heat, it’s more like 30x.

Even if everyone somehow had enough heat pumps, installers, and capital to switch the entire country to heat pumps, the electrical transmission grid would collapse long before it could work, even if generation (historically an issue) wasn’t a problem during these coldest days. Which it tends to be, and has gotten worse with the switch to renewables.

This was a known issue that could have been addressed with several decades of prior notice, but at great expense.

So wasn’t.

Re:The five-year engineering feat Germany pulled off in months by jacquesm on Sunday December 11, 2022 @04:51PM (#33947937)
Agreed, this was entirely preventable. The grid is under significant stress already due to the electrification of transport (and likely to become much more stressed on account of that in the near future) so all this is beginning to add up to a perfect storm.

Big European cities have pretty crummy infrastructure and upgrading that is both costly and time consuming. The next years will give a massive boost to energy independence though, which in many ways is a good thing, it's just that we are no longer in control of the timetable and given the fact that until not all that long ago at least my country was selling their gas for wholesale prices that were pretty much a giveaway I really wonder why nobody seems to be doing much in terms of long term planning. Frustrating.

For the heating BHKWs (Blockheizkrafwerke) of many cities in Germany it's still cheaper to run on gas than switch to burning oil. Since the communal industry are legally structured as companies, the mayors aren't allowed by law to switch to oil if it is more expensive, even though it could ease the shortage.

In Poland, coal prices absolutely skyrocketed because Russian coal isn't available anymore & consumers directly interfer with the market.

Relatively, Gas is still cheap. If people all would switch to electric heating quickly, electrity prices would go up proportionally because we would need to buy more form neighbouring countries in close-border regions to keep the network stable.

Re:The five-year engineering feat Germany pulled off in months by jacquesm on Sunday December 11, 2022 @12:05PM (#33944967)
In the EU the electricity price is pegged to the price of natural gas. This results in a lot of weirdness, such as the price of solar and wind power energy being the result of what natural gas costs, even though they have nothing to do with each other.
Re:The five-year engineering feat Germany pulled off in months by bionade24 on Sunday December 11, 2022 @12:29PM (#33945227)
No (at least in Germany, can't speak for whole Europe) the price is settled by the most expensive electricity producer currently serving. Gas power plants are used regularly to stabilize the network, but they didn't drive the electrity price that high because Germany has way more gas power plants than usually necessary. Only the modern ones were used.

This year though, since France struggles so hard with their nuclear power plants, gas power plants are running 24/7, even older, less efficient ones.

This led to the price of electricity determined by gas power plant operation costs all day.

That seems even more broken. The annoying thing is that the case for renewables is polluted by these kind of price fixing measures.

Re:The five-year engineering feat Germany pulled off in months by markus92 on Sunday December 11, 2022 @02:20PM (#33946485)
The price set is the marginal price for the last MW of capacity required (which is the most expensive one). No other way to do it I guess: if you give the cheaper producers less than the most expensive ones, they have the economic incentive not to supply until they get the higher price.
Re:The five-year engineering feat Germany pulled off in months by jacquesm on Sunday December 11, 2022 @04:51PM (#33947951)
A cost+ model would make a lot more sense in a situation like that.
Re:The five-year engineering feat Germany pulled off in months by lazide on Sunday December 11, 2022 @07:10PM (#33949128)
Then all the cheap producers would be ‘down for maintenance’. Enron did a lot of tricks like that.
Re:The five-year engineering feat Germany pulled off in months by jacquesm on Sunday December 11, 2022 @09:45PM (#33950274)
I highly doubt that would fly in the EU. Privatization always was 'at arms length', piss off enough bureaucrats and I'm pretty sure you'd find yourself nationalized pdq. Telcos have had the sharp end of the stick pointed at them a couple of times now and have each and every time folded rather than to see how sharp it really was, I don't think energy companies would fare any different, especially not because energy is more or less a first level need and telco services a second or even lower level one.
Re:The five-year engineering feat Germany pulled off in months by lazide on Monday December 12, 2022 @10:42AM (#33955859)
They figured out Enron too, after tens of billions worth of damage. Didn’t stop them.

I do agree that the EU isn’t likely to be hands off enough to ever let it get to that point though. It was a particularly dumb set of regulatory decisions that let/encouraged Enron to do what they did.

But market forces are powerful motivators.

Re:The five-year engineering feat Germany pulled off in months by foepys on Sunday December 11, 2022 @10:08AM (#33943797)
France (which built out nuclear power like no other country) is a big importer of this electricity because their nuclear power plants are largely shut down due to urgent maintenance work. Paris is in the process of doing exercises to prepare for blackouts in the coming months.
Re:The five-year engineering feat Germany pulled off in months by panick21_ on Monday December 12, 2022 @12:04AM (#33951081)
Its also used for electricity at least on the graphs I have seen. Maybe I mixed up total electricity production or energy consumption.

Even so, not using any LNG for electricity and replacing coal is just if not more valuable.

And of course the reluctance to electrify heating for houses is linked to the bad overall energy policy.

Heating could have been switched to heat pumps (and will need to anyway at some point), had they not bathed in natgas for tens of years (thanks Schröder!).

That it wasn't done doesn't make it less needed?

Schröder wasn't around in 1969 when the first contracts for russian gas have been closed.

> Heating could have been switched to heat pumps

We have 12 million gas boilers. Last year, we had an install capacity of 165k heat pumps. The government is trying to up that to 500k per year. Even in this (somewhat optimistic) scenario, that would be 24 years of work.

So yes, we need to start doing that. But until last year, we had 16 years of governments that did fuck-all for renewables.

Running an electrical space heater would maybe not cost more than a flight to a warm country if we had any kind of (long term) cheap electricity generation like nuclear. I'm German and I visited Russia recently, and their energy is dirt cheap due to it all being nuclear—it's crazy how you can just run a space heater and now worry about being bankrupted by it.
Re:The five-year engineering feat Germany pulled off in months by mqus on Sunday December 11, 2022 @11:10AM (#33944384)
nuclear energy generation is "cheap"? Are you sure? According to e.g. [1], it's the most expensive power source and getting more expensive each year. It's probably "cheap" due to all the subsidies and the conditions on the subsidies setting certain prices.

Sure, it didn't help shutting down nuclear reactors prematurely but building new ones certainly is not the cheapest strategy.

[1] https://www.worldnuclearreport.org/IMG/pdf/wnisr2022-hr.pdf (Page 280, Figure 52)

Re:The five-year engineering feat Germany pulled off in months by morcheeba on Sunday December 11, 2022 @11:42AM (#33944721)
That's a great graph, thanks. But there is a whole lot factored in to those numbers. Check out this paragraph in the next page:

>The running of aging nuclear power plants generally leads to higher operating and maintenance costs. Only in the U.S., the nuclear industry has claimed a cost reduction of 35 percent since 2012 to US$29.4/MWh in 2020—the lowest since the collection of industry-wide data in 2002—in particular due to a 57 percent drop in capital expenditures over the period.

Here's the source they use - it explains this much better: https://www.nei.org/resources/reports-briefs/nuclear-costs-i...

So, what's the difference? Nuclear is different because it costs the same to run per hour no matter how much power is generated. So, when demand is down, costs remain the same - while coal and gas can just use less fuel, which is their major cost. The risk that nuclear won't be able to run at higher loads increases costs overall. If market forces could guarantee usage, then costs would lower.

There's definitely a lot to explore here... power pricing is complicated!

Re:The five-year engineering feat Germany pulled off in months by crote on Sunday December 11, 2022 @01:32PM (#33945900)
"Market forces" by definition do not guarantee usage, as they would use the cheapest form of electricity.

As it turns out, the industry is willing to build new nuclear if and only if 1) the government guarantees 100% usage of the offered capacity 2) the government is willing to pay for the difference between the market price of electricity and a (higher) fixed fee.

The fixed pricing of nuclear is often way higher than the market price - even with 100% capacity usage. It is simply not able to compete with dirt-cheap solar and wind energy. The free market is aware of this, so they are unwilling to take the risk without guaranteed government subsidies.

Re:The five-year engineering feat Germany pulled off in months by Archelaos on Sunday December 11, 2022 @04:03PM (#33947470)
There are a lot of hidden costs with nuclear energy. For example, I don't know of any country where the insurance costs for nuclear power plants are not capped. This means that in the event of a disaster, the costs have to be borne by the taxpayer. The same applies to the costs of final storage. No one knows how much this will cost over the next million years or so. If all these costs were included in the calculation, it would become clear that nuclear energy is extraordinarily expensive. Of course, this is not in the interest of the nuclear companies (the same ones that run fossil power plants, by the way), because the lower the more optimistic their believers are, the more money the companies make.

Not sure where you got this - nuclear gives only about 20% of electricity in Russia. 60% of electricity is produced from natural gas, and the rest 20% is from hydro stations.

Re:The five-year engineering feat Germany pulled off in months by jeltz on Sunday December 11, 2022 @12:23PM (#33945168)
So why is electricity cheap in France and expensive in Denmark? Denmark has the most expensive electricity in Europe and they are mostly wind and they often have to import from Sweden and Norway (which is also why electricity is expensive in southern Sweden). If we look at countries nuclear does not seem very expensive. Not the cheapest (that is probably Russian gas followed by hydro) but certainly less expensive than wind power.

The day-ahead price for Denmark seems to be very close to the price in Germany. Much of the high price is taxes.

(I don't know how much of the tax went to subsidising earlier wind power construction.)
