Bolji, bolji u čemu? A članak i istraživanje su Quote In that same span, however, battery EVs could drop to around 125 grams, and perhaps even down to 50 grams if the price of renewable energy were to drop significantly. “Once we decarbonize the electric grid—once we get more and more clean sources to the grid—the comparison is getting better and better,” Paltsev says.

Sestre Bronte Posted July 19, 2023 Posted July 19, 2023 ali čemu uopšte ta dilema? to je kao da raspravljamo da li je lepše da me ubije metak u glavu ili srce ne valja ni jedno ni drugo, električni malo manje ne valja i to je sve 5

Desmond Bojčinski Posted July 19, 2023 Posted July 19, 2023 (edited) Besnilo na stranu, to je sigurica da ginemo, nego što me pored državnog zdravstvenog osiguranja tera gljivice da lečim kod privatnika sa najfinijim kremicama.

Ne promeni, reda veličine da nam se prosečan životni vek ne prepolovi? Ili da nas ne ugine 4 milijarde na primer? Možemo. Na primer, naučnik Vaclav Smil smatra da može da se prepolovi potrošnja energije i materijala na nivo 60ih ili 70ih i ništa se bitno ne bi izgubilo. Quote You debunk overly rosy projections by techno-optimists, who say we can solve all our problems with smarter computers, and economists, who promise endless capitalist growth. In many countries, the downside of material growth now seems greater than the upside, which leads to what you call “anthropogenic insults to ecosystems”. Is that a fair summary? Yes, I think so. Without a biosphere in a good shape, there is no life on the planet. It’s very simple. That’s all you need to know. The economists will tell you we can decouple growth from material consumption, but that is total nonsense. The options are quite clear from the historical evidence. If you don’t manage decline, then you succumb to it and you are gone. The best hope is that you find some way to manage it. We are in a better position to do that now than we were 50 or 100 years ago, because our knowledge is much vaster. If we sit down, we can come up with something. It won’t be painless, but we can come up with ways to minimise that pain. So we need to change our expectations of GDP growth? Yes, the simple fact is that however you define happiness, we know – and we have known this for ages – that the amount of GDP is not going to improve your satisfaction with life, equanimity and sense of wellbeing. Look at Japan. They are pretty rich but they are among the unhappiest people on the planet. Then who is always in the top 10 of the happiest people? It is the Philippines, which is much poorer and smitten by typhoons, yet many times more happy than their neighbours in Japan. Once you reach a certain point, the benefits of GDP growth start to level off in terms of mortality, nutrition and education. Is that point the golden mean? Is that what we should be aiming for rather than pushing until growth becomes malign, cancerous, obese and environmentally destructive? Exactly. That would be nice. We could halve our energy and material consumption and this would put us back around the level of the 1960s. We could cut down without losing anything important. Life wasn’t horrible in 1960s or 70s Europe. People from Copenhagen would no longer be able to fly to Singapore for a three-day visit, but so what? Not much is going to happen to their lives. People don’t realise how much slack in the system we have. https://amp.theguardian.com/books/2019/sep/21/vaclav-smil-interview-growth-must-end-economists Edited July 19, 2023 by eumeswil 1 1
Sestre Bronte Posted July 19, 2023 Posted July 19, 2023 Naučnik Vaclav Smil nije u pravu, on samo posmatra jednu stranu - našu sposobnost da nešto uradimo. Potpuno zanemaruje drugu stranu - našu želju da nešto uradimo. igrom slučaja mi je klip izmamio bled smešak pre par minuta
Venom Posted July 19, 2023 Author Posted July 19, 2023 (edited) Iako su zorglub i desboj otporni na podatke, samo da ostavim da je transport oko 20% svih emisija, a od toga putnički saobraćaj skoro pola. Poznat sam ovde kao ljubitelj automobila, pa tako i električnih, ali prelazak na električne automobile bi bio napredak. U stvarnosti nam treba drugi sistem, ali u međuvremenu ima razlike da li će se problem smanjiti ili neće uopšte. Ni u jednom aspektu života ne postoji sve ili ništa rešenje, to je tačno i za banalne stvari kao što su skidanje viška kilograma, pa do rešavanja teških problema koje još uvek ne umemo da rešimo kao što je ovaj. Do sad je sve bilo sranje, od sutra okrećemo novi list - to ne uspeva nikad. Svi ovi izmišljeni argumenti su uglavnom iz iste kuhinje kao i recimo za obnovljive izvore energije - za električne automobile se uzimaju najgore moguće procene, za ostale najbolje moguće procene. Baterije u automobilima ne traju samo 10 godina. * trebalo je da piše "more CO2" Cilj svega toga je da baci ljude u depresiju i dignu ruke od bilo kakvog pokušaja da bi ljudi koji po danu mlate milijarde nastavili to da rade. Problem postoji i nema mesta ni pesimizmu ni optimizmu, nijedno od ta dva neće rešiti problem. Postoje mnoga rešenja koja su moguća već danas i koja će problem učiniti manjim.

U svakom slučaju, za tako važno pitanje, vrlo je karakterističan manjak istraživanja sprovedenih od strane nacionalnih institucija, ili u združenom pokušaju više država. Tabelu koju si ostavio bukvalno je kompajlirala jedna osoba, tako da...
Sestre Bronte Posted July 20, 2023 Posted July 20, 2023 ne postoji manjak istraživanja i ne postoji statistika koja mi odgovara, sve su loše 1
