Sinossi
«Non sono né un pessimista né un ottimista, sono solo uno scienziato che prova a spiegare come funziona davvero il mondo». Su cosa si regge un sistema globale in cui per fare arrivare un pollo in tavola è necessaria una quantità di energia pari a mezza bottiglia di greggio? Tra i massimi esperti di scienze ambientali, Vaclav Smil descrive con straordinaria chiarezza i meccanismi complessi che permettono il nostro benessere e immagina, per noi, un futuro possibile. Il mondo in cui viviamo consuma 370 milioni di tonnellate di plastica l'anno, 150 milioni di ammoniaca, 1,8 miliardi di tonnellate di acciaio e 4,5 miliardi di tonnellate di cemento. Il lavoro ormai decennale di Vaclav Smil si fonda su una certezza incrollabile: per affrontare qualsiasi problema in maniera efficiente è necessario conoscere i fatti e partire dai dati. Accompagnati nell'esplorazione di principî e macrosistemi ci scopriremo di volta in volta sorpresi, indignati, fiduciosi. E, a lettura ultimata, certamente più informati e consapevoli.

Recensioni
This was an extremely frustrating book. For someone who claims that we need to have humility when thinking about the future, Vaclav Smil comes across as arrogant and surprisingly poorly informed. Where do I even start... 1). Decarbonization. While Smil is correct that we can't decarbonize as fast as Leggi tutto
How Society Works (minus Capitalism) ... Preamble : --I was eager to read Bill Gates’ favourite author explain “how the world really works”, to unpack their ideology. While Gates is a liberal (i.e. cosmopolitan capitalism, see later) technocrat with more enthusiasm towards technocratic fixes (he made hi Leggi tutto
Same as his old books. Vaclav is good at numbers, he connects the numbers and constructs a narrative; at the end of the day its a statistics book masqueraded as a coherent english book. Is the book interesting NO Will you read this book again NO Why did you pick this book in first place? It's near to Leggi tutto
Vaclav Smil is a realist. When most people talk about carbon neutrality, what they have in mind is that the electricity grid of a country will be powered by mostly energy from renewable sources. However, the production of the four pillars of our material world - food, plastic, steel and concrete - r Leggi tutto
I am not a pessimist or an optimist, I am a scientist. There is no agenda in understanding how the world really works. How the World Really Works could be considered the capstone to Vaclav Smil’s impressive career in interdisciplinary research and analysis: having written over 40 books and 500 papers Leggi tutto
I've been sitting here looking at the screen thinking how to write this review. While I read this book, I did related research and have spent weeks on it, more than the dates listed. I am laughing, because I read this book because it was attacked by two very good scholarly friends of mine. As a Left Leggi tutto
I eat fossil fuel. I live in fossil fuel. I commute in fossil fuel. Fossil fuel is God. Period. If I elaborate, I eat(cheaply and abundant) because of the higher yields in rice, wheat and many vegetable crops with advent of fertilisers. why higher yield is a precondition? With normal yields - land, wat Leggi tutto
This is a gripping and intense book, one which will leave most readers more knowledgeable and less happy. How the World Really Works has one clear point to make: that transitioning the world away from fossil fuels is much, much harder than it seems. To make this case Smil presents a torrent of resear Leggi tutto
