Electrical power + water = rocket fuel. You don’t have to use kerosene to launch to space - not that it’s the highest priority anyway.
Why do you equate renewables with primitivism? What exactly stops you from building a skyscraper in a renewable-powered world? We do have green steel, concrete and glass. Besides, most use cases do not require skyscrapers in the first place, and they are seen as undesirable by many urbanists.
Now, yes, switching to sustainable lifestyles is not without compromise here and there, especially on the first stages of green transition. We have to put our effort into this, and there’s no way around this. But with rational organizing, we can end up making something so much better!
- Properly developed public transportation minimizes time and comfort losses associated with this mode of commuting, while making streets and air cleaner, freeing up plenty of space for pedestrians and buildings.
- Comfortable high-speed rail minimizes the need for planes, enabling high-speed travel without all the airport controls and inconveniences and with plenty of amazing vistas.
- Locally sourced seasonal varieties bring back the sense of excitement and allow you to explore so much more than just apples and oranges - there’s a trove of underdeveloped cultivars waiting for their time to shine!
- Plenty of said cultivars are not particularly demanding; also, green fertilizers (for example, microbiological ones, alongside good old manure and compost) are available and can be produced at any scale you need without the need for fossils.
- Easily repairable (user-repairable wherever possible) tech removes financial and organizational anxieties about breaking your devices. Something broke? Just…take spare parts and an hour, and it’s good as new.
- Clothing can always be torn and reassembled in new creative ways! This opens up endless possibilities for creativity, and if you personally don’t like it, I’m pretty sure a local atelier will be happy to help you.
- Community is key to urban living! With more interaction between you and your neighbors and the culture of common responsibility over shared resources, you can turn any “box” into a sprawling place people love to live in. We need to combat the individualist culture to make it work, though.
In this age of sustainability, there’s no issue in having a smartphone, or laptop, or whatever you write this on. In fact, right now there are tech brands oriented at sustainability, long-term support, user repairability and more. Fairphone, Framework, you name it!
We can build our tools, appliances and toys in a post-fossil fuel world. And we can make use of the materials we’ve already extracted to make it even greener.








The thing is, there’s no need to rebuild the world from the 1850s.
We already have the required machinery and energy. We can make use of what we have, even fossil-powered, to speed up the green transition. Our only goal is to keep it going at a growing pace.
As per agriculture, there are sustainable solutions that I addressed in my other response to you. There are green fertilizers, and there are also genetically modified plants able to produce their own pesticides. There are also innovations in logistics and food sharing initiatives to make less food rot without use.
We have the knowledge, we have the energy. What we lack is the political will to shut down those standing in the way for their own gain over our collective future.
