German energy giant RWE has begun dismantling a wind farm to make way for a further expansion of an open-pit lignite coal mine in the western region of North Rhine Westphalia.

I thought renewables were cheaper than coal. How is this possible?

I think this headline is misleading.

A better headline might read: “Coal found beneath wind farm. Turbines dismantled to make room for mining operation.”

[–] youRFate@feddit.de 53 points 1 year ago (2 children)

Still, its lignite, they should cease all mining operations.

[–] KSPAtlas@sopuli.xyz 34 points 1 year ago (3 children)

Lignite is the worst coal, most polluting and least energy dense afaik, why would you bother mining it

[–] youRFate@feddit.de 15 points 1 year ago

Because they get subsidies from the govt bc they employ a whole region and are a super big energy company. They need to be dismantled.

Delete this InfoWars-level bs misinformation meant to smear clean energy.

One small privately owned wind farm is being disassembled, this is not a general new policy or anything signalling a shift away from clean energy.

Ban straws! (even though disabled people need them and they create negligible pollution)

Replace your car with an electric one! (even though it still works fine and will end up in landfill, never mind the environmental cost of producing the new one, or the source of the electricity it uses)

Reduce your carbon footprint! (even though its a term we invented ourselves to shift responsibility to you, while we fly our private jets around creating more pollution than you ever could in 10 lifetimes)

Recycle! (even though 90% of it ends up in landfill anyway because we don't want to pay to actually recycle it)

All equates to

Look the other way while we continue to rape the planet and blame it on you!!!

Never forget - capitalists (and the governments they're co-dependent on) only want more money, they don't car about you or me or the planet, only about themsleves and the numbers in their accounts, and they will never willingly stop doing whatever it takes to make more.

[–] corsicanguppy@lemmy.ca 66 points 1 year ago (9 children)

or the source of the electricity it uses

Oh, quit this noise. In the same countries where electric cars are becoming common, wind/water/sun-produced energy is also on the rise. Electric cars decouple the energy used from the means of production in ways that gasoline will never have, and the potential outweighs the temporary conditions of power generation in socially backward areas like Darfur and America.

While I partly agree with your argument at the end of your comment, I think your examples are really unfitting.

Only single-use plastic straws are banned. There is also an exemption for straws that are necessary for medical reasons. The needs of disabled people are included in the exemption. https://www.europarl.europa.eu/doceo/document/E-9-2021-003536-ASW_EN.html

If people buy a new car, the old one (if still functional) typically enters the second-hand market, not the landfill. There is no reason why this would be different if the new car is an electric vehicle.

The carbon footprint is a perfectly fine concept on its own, the problem is just that some people shit on it with their private jets, which are a legitimate concern. Some people also argue that "most of the pollution is done by corporations, not individuals", completely ignoring the fact that these corporations only do it while producing goods for the people. That does not mean that we can just blame the people for it, but everybody has the responsibility to vote for policies that keep the corporations in check.

Recycling is really bad in some countries, but works pretty well in others. For example in Germany 56% of plastic waste is recycled, 44% burned. 90% of paper is recycled. https://www.quarks.de/umwelt/muell/das-solltest-du-ueber-recycling-wissen/#l%C3%B6sung4

[–] AngryCommieKender@lemmy.world 11 points 1 year ago

We've made electric powered airplane jet turbines. If the rich want private jets, we should require those to be EVs. I don't give a shit that the tech is untested, and neither do they judging by that "submarine."

A new EV breaks even with a used car in less than a decade. It does not matter if it is getting its energy from coal, it still will emit less carbon within a decade.

Recycle! (even though 90% of it ends up in landfill anyway because we don't want to pay to actually recycle it)

90% of plastic recycling. That is thanks to the oil companies who saw backlash against the ridiculous amount of plastic in the 70s and decided to invent a resin code whose symbol mimicked the recycling symbol. Recycling centers were flooded with a ton of plastic which they did not have infrastructure to actually recycle. China took it for a couple decades and then it became unprofitable for them. Basically only resin codes 1 and 2 are recyclable. But most people think all of it is. Absolutely recycle metals. If your city has recycling pickup and you are not recycling stuff like aluminum, you kind of suck.

[–] MightEnlightenYou@lemmy.world 11 points 1 year ago

I'm from Sweden, we're among the best in the world at recycling. We have closed all our landfills and even import combustible trash to burn for energy (we clean the fumes extremely well).

Every time I see a discussion about trash anywhere in the world I get sad that people are so uninformed about what's possible.

One Swedish company, Swedish Plastic Recycling, is currently building a recycling plant that will be able to handle ALL of the country's plastic waste and automatically recycle almost all of the kinds of plastic there are.

This is even profitable if done right.

I live next to this coal mine and the wind farm is on my monthly Autobahn trip right next to me. Maybe to shed some light on the "why":

The coal mine was scheduled to be mined until 2038. The plan was to extend the mine to the west, the wind farm is to the east of the coal mine. RWE of course has big investments into mining this lignite until the very last possible day. There are problems with extending to the west though: old towns still exist there and the residents would of course love to stay in their homes the family had for generations. To the east, where the wind farm is, there is nothing but fields and some wind turbines. There are about 150 turbines in the wind farm and ~15 of them are standing where the mine is extending to now. Those 15 also were the first to be built for the wind farm and they are nearly at the end of their lifespan, some of them are even deemed structurally unsafe.

Of course it would be better to stop mining the lignite but decades ago the contracts with RWE were made and just forcing a company out of a contract that is worth billions of Euros is extremely bad precedent and would hinder future investions. Buying out the contract to cease mining faster also was not possible, because RWE was unwilling to settle for a reasonable sum of money.

So, if I'm reading this correctly, this is the Konigshovener Hohe wind farm which is built on the site of the Garzweiler open-pit lignite mine. According to this article, the site was inaugurated in 2015 with 21 Senvion turbines.

The problem is, Senvion went out of business in 2019, and customers have been struggling to support their turbines. Apparently the Senvion design is exceptionally dependent on software access. Siemens and others have stepped in to offer support contracts to Senvion turbines in good working order, but with the opportunity to mine more lignite at the site, maybe RWE felt that it was time to spin down the Senvion turbines.

It seems like there may be many factors in this decision.

[–] teeps@feddit.uk 14 points 1 year ago

Thanks for providing this context. From what you say it sounds like a bad initial decision from RWE - tieing themselves in to 'wind turbine as a service'doesn't seem sensible.

[–] BilboBargains@lemmy.world 14 points 1 year ago (1 children)

We should be using open source solutions for things like energy security. It's not like our civilization can run without energy generation. The control ought to be in the hands of people, not corporations.

It's about density. Renewables Are great, but not on terms of value add per square foot. The coal under the wind mill is worth orders of magnitude more than the windmill.

And, it's not as bad as it sounds. In general, the number of windmills keeps increasing.

[–] UlrikHD@programming.dev 30 points 1 year ago (6 children)

If you care about energy density, nuclear is the best solution, not coal. I guess Germans don't care though

[–] Hyperi0n@lemmy.film 18 points 1 year ago (2 children)

Germans literally shut down all thier nuclear power in favour for coal power.

[–] mineapple@feddit.de 16 points 1 year ago (2 children)

It was meant to be replaced by renewables but our minister of economics dumped the whole solar and wind turbine industry. Additionally his party made up bullshit rules about a minimum distance for turbines to households, which was apparently 10x of the reasonable distance and which made it very hard to find spots in densely populated Germany. And to this day, the federations with a renewable energy surplus have to pay more for electricity than those who give a shit about renewables. -it is discussed to be changed now but idk

That's an old wind farm that would be due being taken down. Wind turbines have a finite life span, they oscillate slightly and this loosens the ground around the base, so after around 30 years they're taken down. Typically they end up being sold to poorer countries where they're installed on a new base.

The linked article is two sentences long and offers no context or understanding of the situation. It might as well be a headline. The only useful part of it is the photo of the wind farm being dismantled, which also shows a completely different wind farm in the background, on the other side of the expanding mine, that is not being dismantled:

But you wouldn't realize that just from reading the article.

My understanding based on this much better article from Recharge News is that the following information is critical to understanding this decision:

First, the wind farm being dismantled is the Keyenberg-Holzweiler wind farm, which consists of 8 turbines built over 20 years ago in 2001, totaling just over 10 MW of capacity (1.3 MW each). Recently constructed wind turbine power outputs are estimated at a 42% capacity factor, which is to say they generate about 42% of the peak power they're rated for because wind isn't always blowing; this would likely be lower for the older wind farm, but we'll use the current amount. The 10 MW wind farm would have made 3 GWh per month, which based on an average of 893 kWh per month per household is enough to power... 3386 homes [edit: corrected my horrible math]. Not nothing, but not a lot by modern standards considering the Chinese just built a single wind turbine that outdoes the entire Keyenberg-Holzweiler wind farm by half and then some.

Furthermore, as the turbines were built 20 years ago, they were always going to be decommissioned around this time, and that's documented in the agreements back then under which the turbines were built. RWE continues to construct many turbines elsewhere, claiming 7.2 GW of turbines are currently under construction, 720 times the rated output of the Keyenberg-Holzweiler wind farm. They've also built 200 MW of wind capacity in that locality, likely what we see in the background of that image.

If RWE were to replace the turbines that are being decommissioned, the coal underneath them will be worthless by the time the new turbines are decommissioned, and it's supposedly the last of the coal they will be allowed to dig up. They've clearly made huge investments in building out wind power, so this represents the last vestiges of cleaning up their act.

I could not advocate more strongly that coal should be left in the ground, but this all comes down to corporate investors who care more about money than the environment, and agreements made 20 years ago, as well as the fact Germany and much of the EU is still desperate for any source of energy to maintain their current level of industry right now while they're still building out carbon-free generation to fully replace coal/oil/gas. Reality is complex, and to me this isn't as big of an insult to clean energy advocacy as the microscopic EUObserver "article" could lead one to think it is.

Coal is still dying in the West, so let's not go thinking this one last gasp means that trend has changed. If we're lucky, and demand for coal falls quickly enough, they might even scrap this mine before they've gotten everything out of it. Keep pushing!

Didn't the green party in Germany have power in government right now? And weren't they the same guys who dismantled their nuclear plants?

I'm not very informed on German politics but if the answer to both was yes they should really rename their green party to the coal party.

[–] napoleonsdumbcousin@feddit.de 12 points 1 year ago* (last edited 1 year ago) (4 children)

The original contract with the company RWE was made in the 1990s and included destroying whole towns for the coal mine, which was planned to be in use until 2038.

What we see now is a compromise between RWE, the state of North Rhine-Westphalia and the federal government to save the remaining towns and close the mine earlier (in 2030). The wind turbines are from 2001 and are nearing the end of their lifecycle.

I thought renewables were cheaper than coal. How is this possible?

The value is simply more densely packed in the coal under the wind farm than in the surface area of the wind farm.

[–] zkfcfbzr@lemmy.world 20 points 1 year ago

Expanding on this: OP seems to be conflating wind power being cheaper than coal power, with... What? A wind farm being more profitable per unit area than a coal mine?

[–] IHeartBadCode@kbin.social 24 points 1 year ago (1 children)

I thought renewables were cheaper than coal. How is this possible?

This is one of those in general vs in particular things.

In general, yes coal is way more expensive versus renewable energy. In this particular instance, they’re just expanding the site, all of the really expensive stuff like logistics and transportation are already paid.

This is the same reason just keeping old nuclear plants running is cheaper than building a new one. Each industry has expensive parts and cheap parts. If you’re doing something that only expands the cheap parts then you’ll be able to beat out competitors.

[–] DrM@feddit.de 13 points 1 year ago

Additionally those turbines are at the end of their lifespan. They would need to be dismantled and rebuilt anyways, since they became structurally unsafe

12ft paywall removed link

The demolitions are part of a deal brokered last year between Robert Habeck, the Green party's minister for economy and climate action and Mona Neubaur, who is the economy minister for North Rhine Westphalia, to allow the expansion of the mine.

In return, RWE had to agree to phase out coal in 2030, eight years before the previous deadline. "It's a good day for climate protection," Habeck said at the time.

What’s the timeline for getting this expansion built? And what’s the lifecycle of the plant? I understand there are energy scarcity concerns, but how is this the most economical option when it’s ~7 years until they’re supposed to phase out coal?

[–] andrai@feddit.de 13 points 1 year ago

The wind turbines are already at the end of their lifespan and they knew RWE had the license to expand the mine there when the wind turbines where build.

Of course it's economical for RWE, they are not building a new mine. Just continuing their mining operation there for another 7 years.

RWE has no conscience left at all (doubt they ever had one). Coal is scheduled to be faded out by 2030 (recently rescheduled from 2038) and I do wonder if there really was no other option than to demolish those 8 windmills (and the nearby village).

That being said: This is a singular incident caused by long-time contracts of the fading industry. It’s not some paradigm shift in Germany. Coal will be gone soon and new windmills will be build.
