  2. #World2: The End of the World

    It's done. I have finished my series of posts about climate change. I spawned three Storylines. This one about [Energy as a whole](/storylines/world-2), one about [traffic](/storylines/traffic) and a [vegan series](/storylines/vegan). I've found out a lot along the way. But it's not enough. ...

  3. #World2 #Vegan Edition: The Inevitable

    Veganism is no religion, as many claim. I think it's two things: a set of rules that help you easily navigate through the giant stream of consumption. When you follow them, you most likely do the right thing for your body, the environment and in any case for the animals. And it's a mindset. It's the thought that we evolved from other animals and therefore we can't draw a line. ...

  4. #World2 #Vegan Edition: Personal Health

    The reason why I became a vegan in the first place was my personal health. I was not sick, but I felt my veins getting plugged with cholesterol and my metabolism getting enriched with poison. And then, one day, I took the decision to stop. At that point, I didn't know all the details. But I felt better day by day. ...

  5. #World2 #Traffic Edition: A Future Vision of Transport

    In this series, I've collected facts and figures about our transport system and possible alternatives. Cars as we know them are not the future. Flying and moving goods around contributes to the bad reputation of that sector. So what could sustainable transport look like? ...

  7. #World2 #Vegan Edition: Pandemica

    This storyline about veganism started with the climate crisis and already came to its centre, animal rights. But there's one more field to cover: health. Let's start with a part that is mentioned less often. Most of the recent pandemics are caused by transmission paths that involve meat. ...

  8. #World2 #Traffic: Travelling the World

    Cars are everywhere. I guess they are by far the most visible means of transport. But they cover only parts of the emission. Public transport and trains form another sector. But we have that under control. The one that is left is flying. ...

  10. #World2: Special: Coal

    I had to change my publishing schedule a bit for a pressing topic: Coal! Coal is currently the dirtiest of all energy sources. Therefore it's obvious that so many people fight against sacrificing whole villages like Lützerath for lignite open-cast mining. ...

    Going vegan has three pillars. In the last episodes, we have covered some ground on one of them - sustainability and climate protection. In the next posts, I'd also dive into the other aspects. So let's start with speciesism and animal rights. ...

    We seem to have usable solutions for electricity and transport, as it seems. But the third column, heating your living room, seems to be the biggest challenge for carbon neutrality. There are a lot of buildings with a lot of shitty technology built in. So the problem is highly decentral. ...

  13. #World2 #Traffic: Intelligent Taxis

    Yesterday, we had to use a bus from the public transport system as well as a taxi. The bus was almost empty - four passengers only, so both rides were not very sustainable and also not cheap. In Hamburg and some other cities in Germany, there are more intelligent systems now - intelligent hybrids between those two. ...

  14. #World2 #Vegan Edition: Footprint

    Time for a small recap session regarding the vegan lifestyle. In the last post, we found out that meat and dairy have a 14% share in climate change. That brings the average German down from 539% of the available budget to 464%. Solid but apparently only a part of the equation. ...

  15. #World2: How Much Do We Need to Save?

    We know now that we're overshooting more than five times. But also the budget is gone by 2050. At that point, we are not supposed to emit anything anymore. What is left is what the trees, moors and oceans absorb. ...

  17. #World2 #Vegan Edition: Our Behaviour

    The previous article points out the inevitable. We will develop into a vegan world. It's not an option to choose from in the future. It's the opposite. It will be a very expensive option to eat meat, eggs or dairy products from time to time. And as it has no additional value, people will just stop doing it. ...

  18. #World2 - Transport: Electric Cars

    The problem with classic cars powered by petrol for the environment is obvious. For every 100 km, in an average Diesel, you spend 1% of your budget. So after 10000 km your whole annual CO2 budget is blown into the air.

    Also, cars with combustion engines are incredibly inefficient. They use only 20% of it efficiently on average. The rest is heat. Fuel Cells are at about 30% and pure EVs are 64% efficient.

    But EVs carry another problem: their batteries. The production also uses energy. A lot. And it uses resources that are not mined sustainably at the moment. So also EVs carry their burden. Probably even similar in size - breaking even after about 100.000 km.

    So the only sustainable way out is to drive less or more efficiently. And throughout the rest of this series, I'd like to dive away from these facts, that most of us already know. I rather want to explore other possibilities and models and look a bit into a possible future.

  19. #World2: Energy Sources

    Now we know that we in Germany emit four and a half times more than we are supposed to (539% of the budget). We also know that energy is the single most important source of greenhouse gas emissions. But where do we lose that much CO₂? Here are some case studies.

    The primary energy consumption in 2020 was 143 GJ/Person*a. The coal power plant Niederaußem contributed about 0,7% to that energy but it uses up 22,2% of our annual CO₂ Budget.

    In comparison, an average gas turbine emits 670 g/kWh. In Germany, we consume 65 TWh/a through gas, which is 12,6%. This uses up 32,7% of our budget.

    Another scenario: An average person needs 47,7 m² of living space in Germany. A 20-year-old house has a standard of 75 kWh/m²a. If you use gas, this equals an emission of 2,3 t/a or almost 150% of the budget. Gigantic. If you live in a passive house, you can reduce that to 30%.

  20. #World2 #Vegan Edition: The Future

    I'd like to start my journey into veganism with a look into the future. We are on a camping ground, mainly because I'm writing this from the side of a camper van. 50 years fast forward.

    The old couple next to us is classy. They drink their red wine from proper glasses. And they sit in front of a miniature screen watching TV shows each evening. I haven't seen such a thing for a long time. But they enjoy it. He, a man with a white long beard and a lot of tattoos, is a smoker. But he's not into cigarettes. I haven't seen that for decades either. No. He's smoking his food.

    For the whole day, he's following a ritual. He prepared a seitan dough with dozens of spices, precooked it and now it's under the smoker. Soon, it will be roasted on the grill for the final touch.

    What you get in the market, he said, is all fake. You have to do it yourself. It's as cheap as flour, dead simple and the tastiest thing you'll ever eat.

    Then they invited us for dinner.

  21. #World2: Dimensions

    A problem that I have with the climate catastrophe lies in the magnitudes of numbers. When someone says "this emits 5 kg of CO2 equivalent", what does that mean? It's totally abstract.

    So I think, we should make it more concrete. When the IPCC, the main organisation that tracks climate change, released their reposts, they came up with a budget that we have if we want to stay below the 1.5°C. It's 420 Billion tons. For the world in 30 years.

    Divided by 30 and the average expected population of 8,73 Billion People, this makes 1,6 tons per year for every one of us. This is my new reference.

    What we actually emit:

    - Germany: 539%
    - China: 536% (astonishing, right?)
    - USA: 1091%
    - World average: 400%

    In comparison:

    - the german forest absorbs (-) 46,4 %
    - Flight Hamburg - Malaga (Spain) 48,1 % (by train: 4,9 %)
    - Flight Hamburg - Sydney 675 %
    - Niederaußem (a single lignite power plant) 12,5 % (per capita)

  22. #World2: Problem chain

    In the past posts connected in this chain here, I had a short glimpse of the three topics (Traffic, Food and Energy). But I've already seen that any of these fields is utterly complex and never black and white. So before I go into more details on each of them, let's go back to the basic problem.

    Earth thankfully has a greenhouse effect. It would be a cold dead place of -18°C if it wasn't there. This effect is caused by gases in the atmosphere that are transparent in visual light and opaque in infrared light. Mainly water vapour (with short term effects) and CO₂ (with complex long-term lifecycles).

    We have increased the amount of CO₂ dramatically in the last 100 years - from 320 to 420 (by 30%) in the last 60 years alone. We have seen that Earth is significantly heating up. CO₂ pollution is coming from burning fossile fuels - like coal (C) or gas (CH4).

    We use the energy coming from there for global wealth, so we can't just stop it.

  23. #World2 - Energy

    Energy consumption and management is the third train of thought, I want to talk about in this series.

    Energy, on the one hand, is by far the biggest driver of the climate crisis. On the other hand, the world in central Europe faces another crisis fired by heat and drought and by the war in Ukraine and our dependency on Russian gas and oil.

    For the climate, the complex topic splits up into four interdependent areas:

    - electricity (43%)
    - industrial consumption (24%)
    - traffic (21%)
    - heating (12%)

    More detailed numbers with sources will follow. This touches only the energy
    part, the whole climate crisis is much more complex because it entails other
    more efficient greenhouse gases, deforestation and tipping points.

    I have the feeling that I have to increase the frequency of these posts because
    every day something new happens in that sector and I need to get behind that. So
    much for the short kickstart into the energy topic.

  24. #World2 - Veganism

    People usually don't believe that our current food consumption is a major player in the climate crisis. I have to say that the connections are very complicated. They're going from Methane in the digestion cycle of cows through transport to rainforest clearing in Brazil. I'd like to get a grip on that myself. That's why I'd like to dedicate part two of my posting series to this topic.

    On top of that, the climate is only one of many plagues meat consumption causes. It's the main driver of the decline in biodiversity. It causes serious health issues driven by lies triggered by a cruel meat and milk lobby. and by the way, it's completely unethical.

    I myself chose to be a vegan eight or nine years ago and I've learned a lot about the other topics along the way. The possibilities for a vegan diet have increased ever since. The topic is booming. I'm sure it's not a trend that will go away anytime soon.

  25. #World2 - The Problem with Cars

    From the previous post, the problem becomes obvious. While with traditional combustion engines, the amount of kilometres is the most destructive part for our environment, the new electrified vehicles have batteries. And they cause the most damage while they are produced. That means many cars standing around is a highly inefficient way to use such a resource. Even more so with battery-driven cars.

    There are already some approaches:

    Using the battery while the car is standing to store e.g. solar energy produced by a building roof for the night. That seems interesting at the first glance, but unflexible in the long run.

    Recycling batteries gives them a slightly better eco-balance, but it doesn't cover enough.

    The only sustainable solution is a change in our mindset. Why do we have to own cars? Why don't we share them? Why are we willing to stay in traffic jams day-in and day-out?

  26. #World2 - Traffic & Transport

    During Corona, many of us were bound to our homes. From time to time, we had to move our muscles somehow. What I did was go out for walks. Because we also moved into another, new district everything was new and had to be discovered.

    By the end of the lockdown, we knew all of the streets and alleys and secret green pathways of our hood. Funnily we didn't know any of the shops, pubs and restaurants around us, because they were closed.

    But there is one depressing view that follows you when you go through the streets of a city. Millions of parking cars. Gigantic immobile unneeded mountains of metal standing around. Some of them are three times as large as needed. Their design cries "Attention, the boss is now on the road".

    Ever since I can't get this picture out of my head again. Some cars are on the road again. But still, any parking space is filled with such a tin man.

    So why are we doing this to ourselves?

  27. #world2 - The Start

    I'd like to start a new posting series that I call "World 2". It's all about the Seldon'esque crisis we're facing at the moment. The Climate Catastrophe. I'd especially like to go into three different streams:

    Transport: I guess even besides its damage potential for the world climate (and this includes traditional cars and EVs), owning and driving so many cars harms us in many other ways. So it's worth a look on its own.

    Diet: Food and food production is one of the big columns of reasons for the climate crisis. Everyone knows that. But it's also the hardest to give up.

    Energy production: Another topic with hundreds of side effects. We wage wars and fraternise with despots to get resources to produce energy. And we're ahead of another round of exploitation of the African continent.
